What's New in Release 3.14.4?
Release 3.14.4 brings additional streaming functionality through Wowza Cloud to VGADVI Recorder Pro.
New Streaming Functionality
Live Streaming via Wowza Cloud
Using a simple connection code, the power of VGADVI Recorder Pro can easily be combined with the flexibility
and worldwide accessibility of the Wowza Streaming Cloud to universally stream from any live video source. See
Stream your video.
Resolved issues
Along with many smaller bugs fixed in release 3.14.4, the following issues have been resolved:
l A blue line appearing on the right side of the captured image when capturing from an SDI source at
720p
l Inconsistent/inaccurate status results shown when attempting to extract a subset of a large, multi-track
file
Limitations and known issues
This section includes known issues or limitations that affect functionality or usability and ways that you can
work around these limitations.
Affecting encoding
l Encoding with MPEG-4 sometimes results in poor quality.
Workaround: From the channel's stream setup, increase the video bitrate to improve picture quality.
l Video bitrate for MJPEG streams are approximately one and a half to two times the configured value.
Workaround: Verify the actual bitrate on the channel's channel status page and adjust until the correct
value is achieved.
l In multiple source channel layouts, sources cannot overrun the top or left edges of the screen.
Workaround: Avoid using negative values for x and y axis coordinates.
l Encoding is unavailable if a branding logo is placed outside the frame size. (i.e. if the frame is 1024x768
and the logo is placed with an x-axis margin of 1200.)
Workaround: Always keep the branding logo within the frame.
l For VGA sources only, some wide-mode resolutions are not correctly identified and result in a slightly
squished image (e.g. for a 1360x768 source, the detected resolution may be 1024x768).
Workaround: This issue is related to the video output hardware. Test your source to see if it exhibits the
iii
issue. If possible, avoid using wide-mode for VGA displays that exhibit this issue.
l When changing a channel's source from a local encoder source to an external encoder source, it's
possible to have an AAC audio encoding bitrate that is higher than the VGA Grid HD Encoder supports.
The resulting stream or recording may be unplayable and you may encounter a warning about variable
audio bitrate.
Workaround: When changing from local to external sources, delete the channel rather than changing
the source(s). Or, if re-using channels, ensure audio encoding bitrate for VGA Grid HD Encoders is set to
no more than 160 kbps.
l Recordings made with encoded streams from VGA Grid HD Encoders, using AAC audio and AVI file
format are not playable via VLC.
Workaround: Use another media player, such as Windows Media Player; choose a different audio codec;
or save recordings as .MP4 or .MOV files.
l Some cameras are sensitive to EDIDs and are not captured at optimal settings. When capturing from
these cameras, the HD signal may be down-sampled by the camera to an SD signal because the Epiphan
system doesn't share the EDID the camera expects for its HD signal.
Workaround: Contact Epiphan customer support for a custom EDID to resolve this issue.
l Limitation: When audio is enabled on an SDI source where video is already being captured, it takes up
to 15 seconds for the system to detect the audio. Once detected, the audio is properly synchronized
with the video.
Workaround: Start the SDI signal with audio enabled, or check to ensure audio is detected before
streaming or recording.
Affecting streaming
l You may see video artifacts when creating multiple source layouts where sources are partially
overlapped.
Workaround: Avoid overlapping sources in multiple source channels or disable the Keep Aspect Ratio
parameter.
Affecting recording
l You may see video artifacts when creating multiple source layouts where sources are partially
overlapped.
Workaround: Avoid overlapping sources in multiple source channels or disable the Keep Aspect Ratio
parameter.
Affecting the web interface
l It is possible to name two or more channels with the same value. Use of automatic file transfer and UPnP
is unpredictable if this occurs.
Workaround: Ensure each channel has a unique name.
l The automatic file upload (AFU) file queue shows a maximum of 15 files, Newer 15 and Top of the list
buttons do not work. All files are transfered, even though they are not lists.
Workaround: Wait for the queue to have fewer files in the list.
iv
Affecting other areas
l Limitation: Pearl fails to restart after improper shutdown (power cable removed or rapid power cycle).
LED and touch screen blink.
Workaround: Restart Pearl by removing the power cable for 20 seconds, then reattaching the cable and
powering the system back on.

What's in the Box?
What's in the Box?
The VGADVI Recorder Pro is a 2U rackmount server.
Latest Hardware Revision:
VGADVI Recorder Pro can now capture more HD content than ever before. The newest VGADVI Recorder Pros
comes with four HD inputs. Half the inputs are for capturing from DVI/HDMI/VGA sources while the other half
are for SDI sources. As before there are also two S-Video ports.
With this combination of available input ports and applicable DVI, SDI or S-Video adapters/converters you can
bring in signals from nearly any source. This hardware upgrade also provides audio capture support for HDMI
and SDI in addition to pre-existing support for 3.5 mm analog audio input ports.
Previous Hardware Revisions
Previous versions of VGADVI Recorder Pros came with two HD inputs. Many, although not all, previous
rackmount hardware revisions can support the latest software release. Compact versions do not support the
firmware upgrade due to hardware limitations. Use the Firmware Upgrade feature to see if your device is
upgradeable. Note previous hardware revisions do not support HDMI audio capture.
Unpacking the box
The following list applies only to new devices with the latest hardware revision.
1. One "Big Red Button"
2. Two VGA to DVI-I cables
3. Two HDMI to DVI-I adapters
4. Two DVI-I to DVI-I cables
5. Two composite to S-Video cables

Quick Start
Quick Start
This section helps you get up and running quickly with your VGADVI Recorder Pro.
l Step 1: Physical Setup and Power On
l Step 2: Admin Discovery and Login
l Step 3: Setup the Video Source
l Step 4: Configure the Channel
l Step 5: Testing the Stream
l Step 6: Recording the Stream
Before you get started, make sure you have:
l an HD source (i.e. a computer, a tablet, or a phone)
l the appropriate cables or adapters to convert the output to DVI or SDI (if needed)
l ideally, a network with Dynamic Host Configuration Protocol (DHCP)
l a computer with a web browser connected to the same network (this is referred to as the “admin”
computer in the steps below)
l optionally, an audio source such as a microphone or the headphone jack from a laptop . Note that audio
signals sent over HDMI and SDI are supported in the latest hardware revision(s). If you have SDI ports,
your system supports HDMI and SDI audio.
These instructions include steps for setting up and configuring audio. Skip these optional steps if
you do not want to configure an audio source at this time.
Step 1: Physical Setup and Power On
Complete the following steps to prepare and power on the system. Refer to the Front and Back Panel View
section for your system to locate the appropriate input ports.
1. Turn on your HD source and connect the output cable to a DVI-I or SDI port on the back of the system.
2. (optional) Attach a 3.5 mm audio cable from your audio source to the system’s motherboard audio input
port(blue port on the back of the system).
3. Connect the Ethernet cable to the VGADVI Recorder Pro. Connect the Ethernet cable to your network.
4. Attach the power cable to the system and plug it into a power source.
5. Unlock the front panel and press the power button to turn on the system.

VGADVI Recorder Pro User Guide
Quick Start
6. Wait for the VGADVI Recorder Pro to complete the power up sequence. The power LED illuminates and
the hard drive LED flashes during start up.
Step 2: Admin Discovery and Login
The VGADVI Recorder Pro is managed from a web interface. This interface acts as a configuration utility and
system monitor. The first time you access the web interface you will not know the IP address of the system.
The steps below use DNS-based service discovery (a type of zero-configuration networking) to access the
system. Depending on the operating system on your admin computer you may need to install some software
before you can used DNS-based discovery.
This quick start is meant for systems that support DHCP and DNS, however if your system does not
support these mechanisms, refer toConnect to the Admin Interface and Connect via the Epiphan
Discovery Utility for alternative discovery mechanisms. Return to step 3 below you have
completed setting a static IP address for the VGADVI Recorder Pro.

DVI ports are listed with the suffix .vga, SDI ports are listed with the suffix .sdi, S-Video inputs listed with the
suffix .video, and analog audio inputs are listed with the suffix _analog or, for the audio port on the
motherboard: Analog. Digital audio inputs (for systems with SDI ports) are listed with the suffix .hdmi-audio or
.sdi-audio, depending on their source.
The serial numbers for your system will not be the same as the examples shown below.
1. From the web interface, scroll to the Sources section. (You will see more sources than shown below.)
10
VGADVI Recorder Pro User Guide
Quick Start
2. Find the DVI (or SDI) source that you have connected by selecting each DVI (or SDI) source (named .vga
or .sdi as the suffix) and verifying if the preview on the right side of the screen reflects your source
material.
3. Make note of the name of the source, or optionally, change the source name to reflect the data it is
capturing.
To rename the input source:
a. Click on the source name at the top of the source configuration window. The name text becomes
red.
b. Edit the name. The following characters are supported: a-z; A-Z; 0-9; + (plus); - (hyphen); _
(underscore); , (comma), . (period); ~ (tilde); # (hash); [ ]; ( ). Although spaces are also supported, it
is suggested you use underscores to separate words.
c. Press Enter on the keyboard. The name is updated at the top of the screen and in the list of
sources at the left side.
4. Optionally, configure the audio source (if connected):
a. Scroll to the Sources section again and select the motherboard audio source. It is prefixed by the
word audio and suffixed Analog (i.e. aduio ALC892 Analog). The audio configuration page
appears.
b. From the Input source drop-down list, select Line for the blue port at the back of the system.
c. Click Apply.
Source setup is complete. The system automatically detected and adjusted the image capture settings at start
up and will continue to adjust every 60 seconds during operation (interval is configurable). The system’s goal is
to produce the best quality captured image given the source equipment used. Generally no further
configuration tweaks are needed.

Step 4: Configure the Channel
Now that you have confirmed the system sees your source it is time to add and configure a channel for output
of your source. Channels expose your sources to your streaming users and prepare the sources for recording.
By default, when you add a channel, the system names it the same name as its source. If you changed the
source name in previous steps, your new channel's name will reflect the new name.
To add a channel for your source:
1. In the web interface, click Add channel from the Channels section; a new channel is created and the
channel configuration page opens.
2. From the Use video source drop-down list, select your source.
3. Click Apply.
To review and configure the channel:
1. From the web interface, scroll to the Channels section
2. Click the link for your channel; the channel expands.
3. Click Encoding for your channel
4. No need to change anything right now. Review some of the default settings. The four most useful
settings to know about are codec, frame size, frame rate and bitrate.
a. The codec is set to H.264 by default.
b. The frame size should reflect the resolution provided by your source. You can set it to something
different by typing in the fields or selecting an option from the different sizes shown. Scaling the
image (making it larger, smaller, or different aspect ratio) takes some processing power, so it’s
always best to leave this at the value detected by the system unless you know it is wrong or know
you need to scale the size.
c. The frame rate limit is set to 30. This means the system won’t spend extra computing time to
attempt to receive more than 30 frames per second. For perspective, NTSC TV signals use 24
frames per second and most hand-drawn animations show only 12 unique frames per second.
d. The bitrate is set to automatic, and the system will determine the best value.
5. Click Status for your channel.
6. Notice the Stream Info section has an item named Video that reflects the four settings reviewed in prior
steps (the frame rate is specified as <resolution size>@30 for 30 frames per second). It also provides an
indication of the current actual frame rate.
12

You may now optionally add audio to your channel:
7. Click Sources for your channel; the media source page is displayed.
8. Select the audio source to which you connected your 3.5mm audio cable. If you connected to the blue
line-in on the back of the system, the audio source is the audio source without a frame grabber serial
number.
9. Click Apply.
10. Click Encoding for your channel; the Encoding page is displayed.
11. Scroll to the bottom of the Encoding and click the Enable audio checkbox.
12. Leave the default AAC format and audio bitrate.
13. Click Apply.
Step 5: Testing the Stream
The Status page contains a link to the live broadcast stream for your channel.

1. From the web interface, scroll to the Channels section.
2. Click the link for your channel.
3. Click the Status link for your channel.
4. Right-click on the Live broadcast link for your channel and select Open in a new tab or Open in a new
window.
5. The new tab or window opens with the stream displayed.
a. If the signal is not detected, reseat the DVI cable connections and try again.
Your stream setup is complete. Since most of the steps are pre-configured; you are up and running with a
stream very quickly. You can share the live broadcast link with your users.

1-2 User Administration
The VGADVI Recorder Pro has three configured users:
l admin
l operator
l viewer
By default, none of these users have passwords. For security purposes you should add passwords to the admin
and operator accounts.
This section describes the following user administration topics:
l Understanding User Privileges
l Setting and Changing User Passwords
l Removing User Passwords
l Overcoming Lost Passwords
l Configure LDAP
l Changing the logged-in user
Understanding User Privileges
VGADVI Recorder Pro's three user accounts are admin, operator and viewer. The user account names cannot
be changed and the accounts cannot be disabled. By default, none of the accounts have passwords.
Admin
The admin account is the main operator used for all system configuration. This user has access to all options in
the web interface.
Operator
The operator account is a subclass of the admin account. The operator can log in and view all configuration
items but may only make changes to a small number of options. This account is intended for an operator to
start and stop recordings, download recordings, or perform network diagnostics.
Viewer
The viewer account is for all end-users who are permitted to view the streamed channels. By default, when
there is no password, users are not prompted for a username and password when viewing a channel. The
20
VGADVI Recorder Pro User Guide

viewer username and password prompt appears only when there is a viewer password set.
In addition to the global viewer account, each channel can set a viewer password that overrides the global
value. See Restrict access to streams for viewers.
Current User
When logged in to the web interface, the current username is displayed at the top right corner of the screen.

Setting and Changing User Passwords
By default, admin, operator and viewer have no assigned passwords. Both the admin and the operator user
have access to the web admin interface, so you should always set a password for both admin and operator
accounts. Refer to your system administrator for your organization’s specific password requirements.
In addition to setting global passwords for viewers, you can also set access passwords and IP restrictions on a
per-channel basis from the channel's Streaming page. See Restrict access to streams for viewersRestrict
Viewers by IP Address.
Passwords are case sensitive and can use all alpha-numeric keys in the ASCII range. Your password can be up
to 255 characters long, but should not include any spaces.
Setting a user’s password causes the user to be logged out. Be ready to log back in with the new
admin password or have operators and viewers log in with the appropriate new password. Viewers
may need to refresh their browser window or press play in their media player.
If you lose the admin password, refer to the section Overcoming Lost Passwords.
To set a user password:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Highlight and delete the current password for your selected user (the password is currently masked as
dots).
23
VGADVI Recorder Pro User Guide
1-2 User Administration
For security reasons, the current password appears as eight dots regardless of password
length, and even if there is no password set.
5. Highlight and delete the confirmation password for the selected user.
6. Select the user’s password field and type a new password for the user.
The new password must have between 1-255 alpha-numeric characters or special characters
with no spaces. Passwords are case sensitive.
7. Select the user’s password confirmation field and confirm the new password.
8. Click Apply.
9. If you were logged in as the user whose password you just changed, you are logged out and must log
back in with the new password. If you added or changed the viewer’s password, all viewer’s stream will
pause until they log in with the new password.
If desired, you may specify multiple account passwords on the same page before clicking Apply.
Removing User Passwords
If you want to remove passwords for one or more user accounts, you may do so via the web interface. If you
don’t remember the admin password, refer to the section Overcoming Lost Passwords.
Note that viewer passwords can be set on a per-channel basis.
Clearing a user’s password will cause that user to be logged out. Be ready to log back in with the
new admin password. If viewers are watching the broadcast when the viewer password is cleared
they will be logged out. Viewers may need to refresh their browser window or press play in their
media player to trigger the login prompt.
To clear a user’s password:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Highlight and delete the current password for your selected user (the password is currently masked as

To clear a user’s password on a specific channel:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Click the Streaming link for the channel; the channel's Streaming configuration page opens.
4. From the Access control section do one of the two following things:
a. clear the viewer password field; or
b. select Use global settings from the access control drop down.
5. Click Apply.
Overcoming Lost Passwords
If you have lost the password for the operator or viewer account, you can log in to the web interface as admin
and reset the password using the procedure described in Setting and Changing User Passwords.
If you have lost the admin password and you have remote support enabled on the system, you can contact
Epiphan support to request a remote password change. See Support. If remote support is disabled, you will
need to return the system to Epiphan for password recovery. Contact Epiphan support to discuss this option.
Configure LDAP
You can use the Lightweight Directory Access Protocol (LDAP) for authentication into the system. Specify user
roles by using group DNs for users who log in as the administrator, operator, or as a viewer.
The system has only one admin user and one operator: LDAP users log in as either the admin or
operator, they do not have their own private profiles.
25
VGADVI Recorder Pro User Guide
1-2 User Administration
When enabled, LDAP authentication is an alternative to the regular system usernames and
passwords. You may still login as admin, operator or viewer using the passwords for those
accounts. Furthermore, any LDAP users with the name admin, operator or viewer are ignored. The
local accounts are used instead.
For security reasons, you should configure passwords for the local accounts. See Setting and
Changing User Passwords.
These instructions assume you have a pre-configured LDAP server. The server must support anonymous
binding or have a special bind account with search access priveleges. (Note that Active Directory does not
support anonymous binding.)
LDAP referrals, restrictions and failovers are not supported.
To configure LDAP authentication for your VGADVI Recorder Pro:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Scroll to the LDAP authentication section.
5. Click the Enable LDAP authentication checkbox to enable LDAP authentication (or uncheck to disable).
6. Specify the server IP address and (optional) port for your LDAP server (i.e. 192.168.1.101:389) in the
Server address[:port] field.
7. Use the Connection encryption drop-down to specify the type of encryption, if any used by your LDAP
server.

SSL
SSL encryption is used to connect to the LDAP server. The default port is 636.
TLS/STARTTLS
The connection is initially unencrypted then upgraded to TLS encryption is used.
The default port is 389.
8. Specify the fully qualified DN and password for LDAP bind in the Bind DN and Bind password fields.
(The password masked as dots on the screen.) These fields are only needed if your LDAP server does not
support anonymous binding.
9. In Base DN, specify the baseObject in which to search for entries. The system will search this object and
the whole subtree starting at the base DN.
10. By default the search attribute is uid, which is suitable for a unix environment. Specify a different value in
the Search attribute field, if needed. For Active Directory environments, specify userPrincipalName. The
value of this attribute must be unique in the Base DN.
11. In the Administrators (group DN) field, specify the distinguished name of the group users must be part
of to be logged in as the administrator. Users must have the member or unqueMember attribute for the
specified group to be granted Administrator access.
If left blank, LDAP is not supported for Administrators (but can still be used for Operators and Viewers).
12. In the Operators (group DN) field, specify the distinguished name of the group users must be part of to
be logged in as the operator. Users must have the member or unqueMember attribute for the specified
group to be granted Operator access.
If left blank, LDAP is not supported for Operators (but can still be used for Administrators and Viewers).
13. In the Viewers (group DN) field, specify the distinguished name of the group users must be part of to
be logged in as a viewer. Users must have the member or unqueMember attribute for the specified group
to be granted Viewer access.
If left blank, LDAP is not supported for Viewers (but can still be used for Administrators and Operators).
14. Click Apply.
When a user of the LDAP server visits next visits the admin or viewer page for the system, the system prompts
for use the username and password. For ActiveDirectory servers, the user needs to enter his the fully qualified
username (i.e. [email protected]) in addition to his LDAP password.
Users are required to authenticate once to the system and one time per channel they view.
Therefore users see a prompt to log in to the system (the system name is shown) and a second
time to log in to the channel (the channel name is shown).

In one case, LDAP replaces the local viewer account instead of working side-by-side with it.
When LDAP is enabled and the viewer account has no password (either there is no global viewer
password or the channel overrides the global password with a blank password), the viewer must
authentication with LDAP, he may not alternatively use the viewer account with a blank password.

The domain name system server (DNS server) translates human-readable hostnames
into corresponding IP addresses. Specify the system’s IP address if you don’t have a
DNS server on your network. This value cannot be blank unless you are using DHCP.
MTU Size
The maximum transmission unit (MTU) specifies the maximum packet size for transfer
on the network. The default value is 1500, which is the largest value allowed by
Ethernet at the network layer. It’s best if all nodes in your network use the same value,
so only change this value if you know other nodes use a different value.
Configure DHCP
Occasionally, such as when moving your system to a new network, your VGADVI Recorder Pro must switch from
static IP address allocation to dynamic allocation via DHCP. You can accomplish this three ways:
l Restore factory settings, clearing all your custom settings. See Perform Factory Reset.
l Load a configuration file that uses DHCP networking. See Load a saved device configuration.
l Apply a configuration preset that uses DHCP networking. See Apply a configuration preset .
l Change the network settings. See the procedure below.
To configure use of DHCP for networking:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Network link in the Configuration menu; the network configuration page opens.
4. Select the radio button use DHCP, if not already selected.
5. Change the MTU Size value only if needed. See the table below for information on maximum
transmission unit (MTU) values.
6. Click Apply to save the changes; the changes are saved and a message appears asking you to reboot.

value if you know other nodes use a different value.
Tether to a Mobile Network
The VGADVI Recorder Pro supports tethering to a mobile device via USB. Tethered networking can work sideby-side with Ethernet routing and either networking system can be a back-up for the other.
When the system falls over to the backup network type (i.e. from Ethernet to mobile, or vice versa)
all streaming sessions with clients or servers directly connected to the system are closed and the
clients will need to reconnect. You may need to provide a new stream URL (containing the new
IP address) to your viewers. See the channel information page to get the new stream URL.
By contrast, actively published streams are closed and reconnected via the secondary network
(mobile or Ethernet) automatically, permitted the required publishing server is accessible from the
new network.
To configure tethering to a mobile network:
1. Configure the mobile device to allow tethering via USB.
2. Connect the mobile device to the VGADVI Recorder Pro with a USB cable.
3. Connect to the admin interface using your preferred connection mechanism. SeeConnect to the Admin

Configuration presets overview
Configuration presets make it easy to use your VGADVI Recorder Pro in a variety of situations without needing
to reconfigure it. Configuration presets divide the system's settings into the following configuration groups.
(For a complete list of what is included in each group see Configuration groups.)
System
Sources
Network
Channels
Automatic file uploads
Using the Configuration presets section of the Maintenance page, you can create configuration presets using
any number and combination of the configuration groups. Mix and match the settings groups saved together
to create sets of configuration settings needed for each situation. You also always have a special Factory
default configuration preset (which cannot be erased) to help you return to factory configuration without
destructively erasing files saved to the system hard drive. (See Apply the Factory default configuration preset
37
VGADVI Recorder Pro User Guide
1-3 Configuration presets
It's important to note that configuration presets are applied over existing settings. They affect only the settings
groups included in the preset, all other settings are unaffected. Read the Configuration preset considerations
section carefully to understand caveats around using configuration presets.
Example of configuration presets in action
A recording and streaming company brings VGADVI Recorder Pro to a conference as part of a portable rack.
Each conference session needs to be streamed and recorded with a picture in picture layout that includes
identifying information about the presenter in the metadata and the background image for the stream.
Automatic file upload is needed to make sure the files are uploaded right after each session is complete.
The company could bring VGADVI Recorder Pro in a factory configured state and get it ready between each
session, but this requires a trained operator and doesn't allow much time to get multiple operations
completed.
Instead, the company could connect the system to their own corporate network before the show, upload the
required backgrounds, and create channel configuration presets for each conference track. They can also
create network and automatic file upload (AFU) presets for each of the home and remote locations. Once at
the conference, the only changes necessary are to apply the network and AFU preset upon arrival, and the
channel configuration presets between sessions.
Note: channel configuration presets include links to background files used, but do not include the files
themselves see Branding content
Internal network and AFU preset
The company uses this preset when configuring and testing from their corporate network. It uses a static IP
address on their corporate network and AFU that uses ftp to upload to a local ftp server.
Conference network and AFU preset
The company applies this preset to the VGADVI Recorder Pro when they arrive at the conference. It changes
only the network and AFU settings (using a conference-specific IP address and secure file transfer to an ftp
server).
When applying this configuration preset, all other information including passwords, date/time, channels and
source configurations, remains the same.
38
VGADVI Recorder Pro User Guide
1-3 Configuration presets
Conference session 1 preset
The company applies this preset from the corporate office when testing and at the conference prior to
conference session 1 starting. All other preset groups remain unchanged, this preset only affects the channel
(s) and their configuration. This preset includes a channel with a link to the correct background filename (the
background file was uploaded during pre-show configuration at the corporate office) and has metadata
specifying the speaker's name.
Conference session 2 preset
The company applies this preset from the corporate office when testing and at the conference prior to
conference session 2 starting. After applying this preset the files recorded from session 1 remain present on
the system and continue to upload via sftp (if not yet complete), but the channels reflect the session 2
background file name and presenter name.

Apply a configuration preset
When you apply a configuration preset, the system settings for all included configuration groups are updated.
Other settings on the system are not affected. For example if you apply a preset that includes the configuration
groups channnels and automatic file upload, your network settings, passwords, time server, source
configurations, etc are not modified. Similarly if you apply a configuration preset that has only network
settings included, only the network settings change.
If you apply a preset that has the network or system configuration group, a reboot is required.
You can verify which configuration groups are included in a preset by looking at the list to the right of the
configuration preset name. The term 'all' means all groups are included. Otherwise groups are listed
individually.
You may apply multiple presets one after another. If you apply two (or more) configuration presets
that include a particular configuration group, the settings (for that group) from the last applied
preset are the active settings. In short, last in wins.
To apply a configuration preset:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Maintenance link in the Configuration menu; the maintenance page opens.
4. Scroll to the Configuration presets section.

Configuration preset considerations
Configuration presets are groups of settings applied to the system, leaving other settings intact. The following
considerations will help you get the most from your configuration presets.
Channel and recorder index number behavior
Each channel and recorder has an index number. The first channel created on a system is channel 1,
subsequently channel 2, 3, 4, etc. Recorders are also created starting at index 1 with numbers incrementing as
new recorders are created. The channel (or recorder) index number is found to the left of the channel or
recorder name in the web interface:
46
VGADVI Recorder Pro User Guide
1-3 Configuration presets
Configuration presets that contain the channels configuration group specify the channels in the preset by
their index number. This means if you have channels 1, 2, 3 and 4 when you save your preset, applying that
preset will overwrite the configuration of your current channels with indexes 1, 2, 3 and 4. If prior to applying
that preset you also had channels with indexes 5 and 6, the configuration settings for those two channels are
when the preset is applied (because the preset only has 4 channels).
There are three areas where channel (and recorder) index numbers affect what happens when applying
configuration presets. Read Recording StateRecorded files (in channels and recorders) and Deleting channels
for more information.
Recording State
The Configuration groups section of this chapter shows that each channel and recorder's recording state is
included in the channels configuration group. This means that if a channel (or recorder) is recording at the
time you create a configuration preset, it will immediately start recording when you apply that preset. Similarly,
if a configuration preset is saved when channels or recorders are not recording, those channels and recorders
will not be recording when the preset is applied (this means a channel or recorder may stop recording as a
result of applying the preset).
For example, when applying a preset with channel 3 set to record:
l If channel 3 exists prior to applying the preset and is already recording, the file will continue recording
uninterrrupted unless the recording file type is different in the preset (in which case a new file is started).
l If channel 3 exists prior to applying the preset and is not already recording, it immediately begins
recording.
l If no channel with index 3 exists prior to applying the preset, the channel is created and it immediately
begins recording.
Recorded files (in channels and recorders)
Channels and recorders keep a list of files recorded in their Recordings section of the web interface. These files
remain on the system even if the channel or recorder configuration is changed or removed as a result of
applying a configuration preset.
47
VGADVI Recorder Pro User Guide
1-3 Configuration presets
For example, prior to applying your configuration preset, you have channels with indexes 1, 2 and 3; each of
these has five recording files. When you apply a configuration preset that has channels with index 1 and 2 only,
you'll notice those channels each still have the same 5 recording files. Channel with index 3 is no longer
present, but the files are not lost!
Overwritten channel files are still available. To access and download/delete these recorded files, enter the
following into the address bar: http://<deviceIP>/admin/channelN/archive or
http://<deviceIP>/admin/recorderN/archive, where N is the index of the removed channel/recorder.
For example, if a Channel with index 3 is no longer present, its corresponding files can be accessed by
entering the following into the address bar:
l http://192.168.0.183/admin/channel3/archive
If you now create a new channel with index 3 (or load a preset that contains a channel with index 3), you'll find
it starts with five recorded files in the Recordings section. These are the same recorded files that existed at the
start of this example.
Furthermore, if you delete any of the recordings, you are deleting the only instance of those files. Using our
previous example, if you delete one of the five recordings from channel index 1, you'll find that even after
applying different presets channel 1 will have only four recorded files.
Deleting channels
Recorded files are stored on the system based on their channel or recorder number. All files saved for channel
index 1 are in one folder, and all files for recorder index 2 are in another. When you delete a channel (or
recorder), you permanently delete all recordings for that channel (or recorder) even if those recordings were
made while a different preset is applied.
Note applying a configuration preset with a different set of channels or recorders is not the same
as deleting a channel.
When deleting a channel or recorder that has recorded files, the web interface warns you of other
configuration presets that use the same channel or recorder index numbers. When you see this prompt, we
recommend you take a moment to look through the Recordings list to make sure you're OK to proceed with
permanently deleting all the recorded files.
48
VGADVI Recorder Pro User Guide

Branding content
The channels configuration group includes the filenames for logos and backgrounds used in the currently
configured channels. It does not include the image files. Therefore it is important to make sure that between
uses of different channel-related configuration presets you do not delete or replace files listed in the Branding
Content section of the web interface. There is currently no configuration group that includes the Branding
Content files.
EDIDs
EDIDs are uploaded and immediately applied to a specific source. This change remains in place until the user
uploads a new EDID or requests the factory EDID is applied by using the Restore default EDID button (see
Force the capture card to use a specific EDID
If you apply a preset that needs a special EDID, be sure to remember to upload that EDID after applying the
configuration preset.
Configuration presets are not user profiles
Configuration presets should not be confused with the concept of user profiles. Specifically, the following
issues arise from trying to use configuration presets as user profiles:
l recorded files are not removed between application of configuration presets (users could see each other's
files)
l configuration presets can be overwritten and deleted with no password (users could affect each other's
presets)
l branding and recorded files can be deleted, affecting more than just the currently applied configuration
presets (users could erase branding or recordings belonging to other users)
l applying a configuration presets does not clear the settings from groups not part of the preset (user
information is not private)

1-5 Restrict Viewers by IP Address
The VGADVI Recorder Pro permits you to restrict which computers can access broadcasts by building a list of
allowed and/or denied IP addresses. You can do this at a global level for the system and can also override these
settings on a per-channel basis. Both global and per-channel configuration procedures are described below.
IP address restriction is valid for the viewer only and does not affect the web admin interface or the
mobile configuration interface.
If your viewer account has a password, your viewers must connect to the system from a computer (or gateway)
with a permitted IP address and must also supply the username (viewer) and password before they can view
the broadcast.
IP Address restriction is not configurable per channel. Restrictions affect all broadcasts / streams
from the system.
To restrict access by IP address you need to know the IP addresses, or range of addresses for your viewers. By
default all IP addresses are allowed to connect to the broadcast.
If you’re not familiar with creating allow/deny lists, refer to the examples below this procedure for assistance
with crafting your lists.
To restrict viewers by IP address:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin

Table 13 IP Based Restriction Fields
Label
Description/Options
Allow IP's
Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are permitted to view broadcasts from the
system, provided their IP address is not in the Deny IP’s list.
To allow all (except IP addresses in the deny list, if any), leave the field blank.
You can use the Allow list by itself, or in conjunction with the Deny IP’s list as an exception
to a rule in the allow list.
Deny IP's
Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are not allowed to view broadcasts from the
system, unless their IP address is in the Allow IP’s list. If a specific IP address is in both lists,
access to the stream is denied.
You can use the Deny list by itself, or in conjunction with the Allow IP’s list as an exception
to a rule in the allow list.
Examples
Allow List with Distinct IP Addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All
other addresses are denied access to the broadcast.

1-5 Restrict Viewers by IP Address
For example if your system is accessible on your local area network (LAN) and you want to make sure only the
CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow List with a Range of IP Addresses
Sometimes you’ll want a range of computer IP addresses to connect to your system. This may happen when
you have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to
192.168.1.100) and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to
192.168.1.250). If you only want the boardroom computers to connect to broadcasts from the system you can
specify the range of boardroom IP addresses rather than needing to type in each individual address. The allow
list looks as follows:
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous example as a range.
Allow List with a Range of IP Addresses and One or More Specific IP
Addresses
Putting the first two examples together, we want to permit access to IP addresses in the range of boardroom
computers (192.168.1.200-192.168.1.250) and also want to add the desktop, laptop and tablet computers of the
CEO (IP addresses 192.168.1.50, 192.168.1.51, and 192.168.1.75, respectively). Note the first two IP addresses are
consecutive, so they can be added as a second range. Add these IP addresses to the list as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Your list can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny List with Distinct IP Addresses
Another simple allow/deny list is to use the list of known IP addresses to list specific denied IP addresses. All
other addresses are allowed access to the broadcast.
For example imagine your system is accessible on your local area network (LAN) and you want to allow any
computer on the LAN can access the stream except your publicly-accessible boardroom (with IP address
192.168.1.211). You can use the following deny list (leave the allow list empty) to permit all computers except
the boardroom computer:
56
VGADVI Recorder Pro User Guide
1-5 Restrict Viewers by IP Address
Deny: 192.168.1.211
As with Allow lists, your deny list can specify a range of IP addresses, and can specify multiple ranges or distinct
IP addresses in a comma-separated list.
Allow List with a Range of IP Addresses, Distinct IP Addresses, and an
Exception
Building on the previous examples, consider the situation where you want the CEO’s computers (192.168.1.50,
192.168.1.51, 192.168.75) and all boardroom computers (192.168.1.200-192.168.1.250) to access the broadcast,
with the exception of the public boardroom computer (192.168.1.211). Use both allow and deny lists to create
the rule as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny List with a Range of IP Addresses
Converse to the previous examples, consider the situation where you want every computer on the network to
access the broadcast, with the exception of the CEO’s desktop, laptop, and tablet computers. Additionally,
boardroom computers should not be permitted with the exception of the cafeteria computer (IP address
192.168.1.222).
The deny list is an "exception" list for the allow list. So to craft the rule described above we need to allow all the
computers in the local subnet, then deny specific sub-ranges including two groups of boardroom computers
ensuring the cafeteria computer's IP address is not in the deny list:
Allow: 192.168.1.1-192.168.1.250
Deny: 192.168.1.200-192.168.1.221, 192.168.1.223-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75

VGADVI Recorder Pro User Guide
2-1 Identify sources
2-1 Identify sources
A source can be an image, video, or audio from a camera, a computer screen or any device that provides a VGA,
S-Video, SDI, DVI or HDMI video signal and audio signal output.
This chapter covers the following sections:
l Connecting sources
l Previewing captured stream from sources
Connecting sources
You can connect sources to the VGADVI Recorder Pro at any time, either before or after the system is powered
on. Similarly you can disconnect a source from a port and even connect a different source at any time.
Changing the source connected to a port that is being streamed or recorded can result in the
recording stopping or the stream frame size changing depending on how your channel is
configured.
If the frame size changes, viewers may be disconnected and need to re-connect to the stream.
Connect the input sources to the following input ports on the system:
Table 14 Cable and port connections

Audio Input port
The web interface automatically discovers all input source ports and displays them in the Sources section of the
web admin interface.
Each video input on the back of the system is a frame grabber. Input sources are identified by their frame
grabber serial number. Each frame grabber has one DVI port, one SDI port, one S-Video port, and one audio
port. DVI ports are listed with the suffix .vga, SDI ports with the suffix .sdi, S-Video inputs are listed with the
suffix .video, and audio inputs are identified by the word audio. Video sources include a preview of the images

they are capturing. It is a good practice to view the images from each source to confirm what is captured. See
below.
When a source is connected, the system automatically detects and adjusts the image capture settings at start
up and continues to adjust every 60 seconds during operation (interval is configurable). The system’s goal is to
produce the best quality captured image given the source equipment used. Generally no further configuration
is needed.
Previewing captured stream from sources
You can preview the images captured from your sources in the web admin interface. No extra configuration is
needed.
To preview the captured stream/images:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin

2-4 Fine-tune source configuration
In addition to fine tuning channel settings such as frame rate, resolution and bit rate to ensure optimal use of
resources while streaming a quality video, there may be circumstance when you must fine tune the video input
source.
Changing how source images are displayed may cause undesired results, for example
experimenting with the PLL setting may result in the image not being displayed properly. It is a
good practice to backup your configuration settings so that you can revert back to a good
configuration if the changes that you made are not desirable. See Save and Restore Device
Configuration.
This section covers the following fine tuning topics:
l Video is not centered on the screen (VGA sources only)
l Video is too bright, too dark or washed out (VGA sources only)
l Video looks squished (VGA sources only)
l Remove the combing effect on images

Remove the combing effect on images
When frames are interlaced, artifacts from one frame may appear on the next frame. This occurs when a fast
motion video is interlaced. Since each frame is captured from a different point in time, the action captured in
one frame is carried over to the next frame. The result is a blurred image and horizontal lines running across
the video.
To convert an interlaced source signal to a non-interlaced signal.
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin

Force the capture card to use a specific EDID
Extended display identification data (EDID) is data provided by a video display device (usually a monitor) to
describe its capabilities to a video source (usually a graphics or video output card in a PC or another device).
The video source uses the EDID to determine the capabilities of the monitor to determine the resolution, color
depth and other settings that the monitor can support.
EDID is crucial for DVI sources but mostly ignored by VGA sources.
75
VGADVI Recorder Pro User Guide
2-4 Fine-tune source configuration
Like monitors, each video capture card in theVGADVI Recorder Pro contains an EDID. When you connect a VGA
or DVI video source (such as a laptop or video camera), this source sees the VGADVI Recorder Pro's capture
card as a monitor and uses its EDID to negotiate which video signal to send.
Generally the capture card's DVI input correctly emulates a monitor that supports your video source. However
sometimes, particularly if your source uses a custom set of display properties, you need to help VGADVI
Recorder Pro by uploading a custom EDID to force the capture card to report that it emulates a resolution,
color depth, etc needed by your laptop, camera or other video source.
Upload a new EDID
In most circumstances the factory installed default EDID, is sufficient. However, there may be some cases where
a video source uses resolutions that you do not want to use. In that case you can choose an EDID that forces
the VGADVI Recorder Pro's capture card to use a specific set of attributes.
The uploaded EDID is permanently installed on your system and this capture card (a "Source" in the web
interface) will always share the uploaded EDID with the connected video input source.
EDID changes are permanent until you replace them with another EDID or specifically choose to
restore the facotry EDID for a given source. Not even a system-level factory reset removes the
configured EDIDs.
1. To download a new EDID file, go to the Epiphan support web page. The support page opens.
2. Select the support page for VGADVI Recorder Pro.
3. Scroll to the EDID section.
4. Click on an EDID from the list. The file is saved to your downloads folder on your hard drive.

channel can be set up to display the content from one input source, or may capture, stream and record
content from multiple input sources. You can identify your channel by adding a corporate logo, company
information, corporate color and time stamps.
Through channel configuration and fine tuning you can maximize your stream quality, minimize your
processing requirements and bandwidth and specify how the video is presented and streamed to a sharing
destination/viewer.
This section discusses the following topics related to channel configuration:
l Create and configure channels
l Identify a channel
l Preview a channel
l Fine-tune channel configuration

3-1 Create and configure channels
Channels make your sources available for viewing and recording. You choose how you want to configure your
sources to make channels.
VGADVI Recorder Pro gives you a lot of control over how your sources are streamed. You are not limited to
creating a Channel list that is a one-to-one reflection of your Sources list.
You can add the same source to multiple single-source or multi-source layout channels.
For example, you could use the same source in all three of these situations, concurrently:
l as the only source in Channel 1 at 1080p, 30fps, 10,000 kbps;
l as the only source in Channel 2 at 720p, 15 fps, 2,000 kbps;
l and added to Channel 3 as part of a multi-source layout with picture in picture.
All channels, even if they re-use a source, can be streamed and recorded simultaneously. Using the example
above, you could record any combination of those three channels, and stream one, two, or all three of them
using any available streaming methods.
This section covers the following topics for creating channels:
l Create a single source channel
l Create a multi-source layout
l Delete a channel
l Rename a channel
While configuring channels, consider opening a live preview of the channel in another tab or browser window
so you can see the changes as they are applied, refer to Preview a channel.
Create a single source channel
A single source channel displays the output from one source in one viewing screen. By default, channels are
automatically configured with the same name as their source. If you change the name of a source, the channel
name will reflect the new source name. Best practice is to rename the sources as required and leave the
channels to reflect the name. If you wish to change a channel's name directly, see Rename a channel.
In this section you can choose settings that maximize your stream quality, while minimizing your processing
requirements and bandwidth by adjusting frame rate, resolution and bit rate.
Procedures to select a codec for compression, add a time stamp to the stream, and select a layout when two or
more sources are configured are described in separate procedures.

11. If you're not sure what Codec to pick, keep the default, H.264. For help selecting a codec, refer to Finetune channel configuration.
12. Keep the default video encoding preset and video encoding profile for help selecting these values,
refer to Fine-tune channel configuration.
13. Perform one of the following steps:
a. Check the Use current signal resolution as the frame size check box. Typically you want to
broadcast at the same frame size as the source.
Enabling this feature greys out the fields to change the frame size. Changing the
input signal resolution may lead to interrupted streaming and recording. Enabling
this feature may not be suitable for systems where input resolution is changed
frequently.
b. Change the frame size, follow the steps below.
14. Set the Frame size to reflect the same dimensions as your source or as sharing destination. Default
values cover popular resolutions of cameras and display devices such as monitors or choose one of the
following:
a. Type a frame size in the field; or
b. Select an option from the sizes shown, the dimensions will appear in the frame size field.
82
VGADVI Recorder Pro User Guide
3-1 Create and configure channels
Making the dimensions larger, smaller, or a different aspect ratio than the source takes
some processing power, so it’s always best to leave at the value detected by the system
unless you want to specify a particular size.
15. Click the Key frame interval drop-down box to choose how often a key frame (a frame that contains all
the pixels) is used when streaming the video. The longer the key frame interval the smaller the video file
size, and vice versa. The higher the value the faster a user moves through the frames of the video when
using the search function of their media player. For more information on adjusting this feature to
reduce bandwidth and system resources, see Fine-tune channel configuration.
16. If desired, change the Limit frame rate. The default should be adequate in most applications. While
decreasing the limit may improve system performance, you may need to test different values to balance
video smoothness and processing power.
17. Increase or decrease image quality by increasing or decreasing the target Bitrate value when H.264 and
MPEG4 codecs are used. Video with a high level of motion and high resolution, such as a sporting event,
requires a high bitrate.
Raising this value uses more system processing power and bandwidth.
18. To configure the Show time label, see Creating a time stamp in the Customize your channel
19. Use the Background color drop down to select a background color for bars that appear at the
top/bottom or left/right side of the frame if the source doesn't fill the frame.
20. If your channel has audio, check the Enable audio check box and select and audio codec and audio
bitrate from the drop down boxes. For digital audio sources (HDMI or SDI), 48 kHz is often the best value
to select. For more information on audio configuration, see Configure audio encoding settings. For
information on selecting audio codecs, see Choose a codec to maximize your stream quality.
21. If you've selected Motion JPEG as the channel codec, you can configure the Page refresh time. Specifiy a
time in a seconds.
22. Click Apply.
Create a multi-source layout
A multi-source layout channel displays the output from multiple sources in one viewing screen. When a
channel displays multiple sources you can specify how video streams are positioned on the screen. You can
display each source side by side, or position one over the other in a more traditional picture in picture layout.
To create a multi-source layout:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin

d. Enter the position coordinates. Position coordinates are based on where the source’s image will
appear. Each axis represents 100 percent. The first value is the image’s position along the x axis
(horizontal axis). The second value is the image’s position along the y axis (vertical axis).
Coordinate 0,0 is the top left corner of the stream. The x axis continues along the top
to the right side. The y axis continues down to the bottom. The right side is 100 % on
the x axis and the bottom is 100 % on the y axis.
See the examples below to learn how to create side by side and picture in picture layouts.
10. When you have added and positioned all your sources, click Apply.
Example: Side by side sources
You can arrange the sources so they each occupy a part of the screen, but none overlap. Using this option, the
background matte (image or color) will be visible if the sources don't occupy the full size of the frame.
To place sources side by side:
1. Add the source by clicking Add Source, then selecting the source from the drop down list.
2. Enter the size of the image based on the percent of the x and y axis the image will span.
In the example above the left image is positioned at the 0 on the x-axis (left side of the
frame) and 30 on the y-axis (starting approximately one third of the way down the frame).
It spans 50% of the x axis and 50% of the and y axis.
The right image is positioned at 50 on the x-axis (half way into the frame) and 30 on the yaxis (about one third of the way down the frame). It also occupies 50% of the x axis and
50% of the y axis. The black background matte is visible where the sources don't occupy
the full frame.

In addition to adjusting typical features such as frame rate, resolution and bit rate to reduce bandwidth and
system resource usage, choose the following settings to maximize your stream quality, while minimizing your
processing requirements and bandwidth:
l Choose a codec to maximize your stream quality
l Codec and file format compatibility
l Adjust video quality
l Upscale or downscale your video image
l Control the matte (black bars) in the video output
l Unstretch the output video
l Limit the frame rate
l Adjust key frame interval
Choose a codec to maximize your stream quality
Before you begin recording and streaming content from a channel, you must select the codec that will be used
to compress the channel’s video and audio content. Deciding on which codec to use depends on how you
prioritize the following criteria:
l Compatibility with streaming formats and file playback options
l Size of the compressed file
l Compression speed
l Image quality
l Number of simultaneous channels recorded and/or streamed
For example, if you require a high quality image, the trade-off might be a larger file size, or slower compression
speed. If you require live streaming and therefore cannot tolerate slow compression, the trade-off might be a
lower resolution.
The table Select a video codec, below, highlights the advantages and disadvantages of supported codecs.
Once you select video and audio codecs a list of available video format and standards specific to the selected
codec is generated and displayed. You can provide the URLs and files to participants to view the broadcast, see

Value
Description
MP3
MP3 provides a common audio format for audio storage.
Supported values are 22 kHz, 44 kHz and 48 kHz. Most digital signals (HDMI
or SDI sources) use 48 kHz audio. Matching the encoded level with the source
level provides the best sound quality by avoiding audio resampling. For analog
signals, 44 kHz provides higher sampling.
Flash (FLV) doesn't support 48 kHz MP3 audio. When selecting this
value you'll need to use a media player (or install ASF browser
plugins) to preview your channel.
PCM
Pulse Code Modulation (PCM) is a standard for digital audio in computer and
other devices such as, digital telephone systems.
Most digital signals (HDMI or SDI sources) use 48 kHz audio. Matching the
encoded level with the source level provides the best sound quality by avoiding
audio resampling. For analog signals, 44 kHz provides higher sampling.
Flash (FLV) doesn't support 48 kHz PCM audio. When selecting this
value you'll need to use a media player (or install ASF browser
plugins) to preview your channel.
AAC
AAC is the default audio codec.
This codec is comparable with MP3, and may have better sound quality with a
similar bit rate. Supported values are 16, 22, 44 and 48K kHz. Most digital
signals (HDMI or SDI sources) use 48 kHz audio.
Matching the encoded level with the source level provides the best sound
quality by avoiding audio resampling. For analog signals, 44 kHz provides
higher sampling.
The maximum bitrate for mono encoding of a 44 kHz signal is 264 kbps. For
stereo, 320 kbps is supported.

Adjust video quality
After sources are connected and channels are created, adjustments can be made to address the different
bandwidth and devices used by the sharing destinations. Ideally you want to choose formats that will reach the
majority of your participants.
Default values have been carefully selected to provide maximum performance in most
environments. In most cases it is not necessary to change the encoding settings.
To encode your video stream:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, select a channel; the menu expands.
4. Click Encoding ; the Encoding page opens.
5. If the selected codec is H.264, click Video encoding preset to define how a video stream is encoded.
Choose one of the following:
Value
Description
Hardware
Accelerated
This is the default H.264 encoding preset. Choose this setting for best
performance.
Software
This matches the default from previous generations of Epiphan products. Choose
this only if you need software encoding or X.264 encoding to match results
created with previous generations of Epiphan products or firmware.
6. If the selected codec is H.264, click Video encoding profile to limit or include video formats that are
supported. Choose one of the following:
Value
Description
Baseline
Choose this option when streaming to an application that requires robustness
and cannot tolerate data loss, for example video-conferencing.

Video encoding profile and preset can be set only when the H.264 codec is selected.
7. Click Apply.
Upscale or downscale your video image
If your source input is larger than your desired output frame size or if you want to stream a less bandwidthhungry version of the content, you can downscale the source by specifying a frame size that uses the same
aspect ratio. By contrast you can also enlarge the image by selecting a value that is larger than the source
resolution.
It is less resource-intensive to upscale or downscale your video at the source (i.e. at computer,
camera, etc). If that isn't feasible, or if you are scaling for multiencoding, follow the steps below to
scale your video.
The VGADVI Recorder Pro conveniently provides a list of common aspect ratios and different frame sizes at
each ratio on the Encoding page.
For example:
l input signal resolution is 1920×1080 (a 16:9 aspect ratio)
l select another 16:9 frame size such as 1280×720
The smaller frame size will downscale the image and use less bandwidth to transmit.
If you select a frame size that is not the same aspect ratio as your source, the result is one of having a matte (bars) appear around the image, or the image is stretched. See Control the matte (black bars) in the video
output for details.
Resizing a video can be more resource intensive than leaving the video at the native resolution.
Although you can change the resolution output by the VGADVI Recorder Pro, it is less of a burden
on your system resources if you change the resolution incoming from the source.

8. Click Apply.
Control the matte (black bars) in the video output
By default, the VGADVI Recorder Pro makes sure that the aspect ratio of input signals is preserved when the
output is streamed. If an input video signal doesn't match the encoded frame aspect ratio, bars are added to
the sides or top and bottom of the encoded stream when the output is streamed and recorded. The color of
the bars is defined by the Background color selected on the Encoding page. See Select the background color
for your channel.
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 640×480 (a 4:3 aspect ratio that is narrower than the input resolution)
96
VGADVI Recorder Pro User Guide
3-3 Fine-tune channel configuration
Borders are added to the top and bottom of the image to preserve the wider ratio of the input.
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 1280×800 (a 16:10 aspect ratio that is wider than the input resolution)
Borders are added to the left and right of the image to preserve the narrower ratio of the input.
If you are seeing bars on your image but would rather have the image fill the whole screen you have to options:
1. Change the output frame size to match the aspect ratio of the input.
2. Stretch the image to fit the output frame size aspect ratio.
These two options are described below.

Unstretch the output video
By default, the VGADVI Recorder Pro makes sure that the aspect ratio of input signals is preserved when the
output is streamed. If this default was overridden or if the channel was created in a version of the software
earlier than 3.11.0, the image is stretched to match the output frame size. The effect may be subtle and may not
be problematic for you, but if you want to resolve this it is very simple to do.
To preserve the source aspect ratio:
1. Connect to the admin interface using your preferred connection mechanism. SeeConnect to the Admin

5. Click Apply.
Unstretching the image causes a matte (black bars) to appear on the sides or top and bottom of
the output. To remove these see Control the matte (black bars) in the video output.
Limit the frame rate
Limiting the frame rate sets a frame rate value that is lower than the maximum frame rate at which the device
can encode images. Reducing the frame rate reduces the number of images captured by the device and
reduces bandwidth usage.
The device's ability to maintain a set frame rate is based on several factors, for example:
l overall system load affects the ability for the device to process pixels;
l available bandwidth;
l the resolution value;
l the type of motion that is captured; and
l number of users accessing the stream.
When adjusting the frame rate, you may need to try different values to achieve the best outcome. The following
table provides the performance expectations when typical settings are used.
To change the frame rate:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, select a channel; the menu expands.

Adjust key frame interval
The key frame interval feature specifies how often a key frame (a frame that contains all the pixels) is used when
streaming the video. This setting also impacts how quickly a video moves through the frames when a viewer
uses the search function of their media player.
Increasing the number of seconds between key frames can significantly reduce your bandwidth and system
resource usage with minor impact to your video quality. A good rule of thumb is to keep the interval between 2
to 3 seconds and decrease the key frame interval as the motion increases. Try different settings and note
changes in the video quality. If your video quality is poor and jittery you may need to decrease the interval
between key frames. If you have unlimited bandwidth and system resources you can choose an option to
stream key frames only.
To adjust the key frame interval:

Choose a streaming option
Each method of streaming media has strengths and weaknesses depending on your audience location,
hardware resources and bandwidth. To help you decide how to publish your content, you must first identify
the number of viewers and how viewers will access your content. Are you streaming live video, or recorded
video. Do you need to stream the content to one client (peer-to-peer), deliver a single stream to multiple clients
(multicast), or provide web-based streaming where multiple clients can access the broadcast (Content
Distribution Network).
Your VGADVI Recorder Pro can stream to individual viewers through HTTP, HTTP Live Streaming, UPnP and RTSP
and can also simultaneously stream to a server such as a multicast server or CDN.
The following tables provide a brief outline of the distribution options. A procedure to configure each
distribution option follows the tables.
Streaming for viewers
Streaming for viewers allows viewers to connect to your VGADVI Recorder Pro and view the live stream.
You can configure whether or not streaming is enabled for viewers. See Disable (and enable) streams for
viewers.
Publishing Options
Use this option to...
HTTP
Quickly stream content to viewers simultaneously. No set up is required. The
VGADVI Recorder Pro is ready to stream content as soon as it is has power
and a configured channel. No other settings are required. Your audience
need only access the URL of the broadcast and they are instantly connected.
This viewing method is ideal for a small number of viewers since streaming
uses your system resources and bandwidth. However a small amount of
overhead is used for each viewer. For more information about using a HTTP
streaming, refer to Stream content using HTTP or RTSP.

Publishing Options
Use this option to...
RTSP
Quickly stream content to viewers. No set up is required. The VGADVI
Recorder Pro is ready to stream content as soon as it has power and a
configured channel. No other settings are required. Your audience need
only copy and paste the URL of the stream into a media player. For more
information about using a RTSP and HTTP streaming, refer to Stream
content using HTTP or RTSP.
HTTP Live Streaming
(HLS)
Stream live over the standard HTTP port 80, making it possible to cross
firewalls and proxies that are normally accessible to other HTTP traffic and
facilitates content delivery to CDNs.
There is approximately a 30 second delay when streaming using HLS.
Stream to a server
Your VGADVI Recorder Pro streams to a server when you want to use a CDN or Multicast. By default, this is not
configured. See Stream content using a Content Distribution Network and Stream content using multicast
streaming for details on configuring one of these two options.

Publishing Options
Use this option to...
Content Distribution
Network
Stream web content to many viewers simultaneously to any geographical
location. A viewer accesses the broadcast from a website using a user name
and password, if required. Using a CDN to host your broadcast is highly
scalable and makes financial sense to website owners since you do not pay
for additional server hardware or routing should your network traffic
increase or decrease.
Using a CDN to stream live content allows you to reach a large
geographically diverse audience and because CDNs perform format
conversion, the stream is platform independent.
For more information about streaming to a CDN, see Stream content using a
Content Distribution Network.
The following options are available to stream video to a CDN:
Epiphan TV - test your video stream using Epiphan’s portal
using RTSP announce - stream live video to a content delivery network
using RTMP push - stream live video to a content delivery network
RTSP and RTMP streaming provides the following advantages:
l viewers can watch the action as it unfolds;
l video quality automatically changes to adjust to changes in
bandwidth;
l reduced bandwidth usage since the player maintains a smaller buffer;
and
l viewers can scroll back through later sections of the video while the
video is streaming.

Use this option to...
Multicast Streaming
Stream content to a multicast IP address where it can be shared with
multiple viewers within the same LAN. All viewers receive the same stream at
the same time. Similar to turning on a radio station, all listeners hear the
same music at the same time.
This delivery method relies on network equipment that supports
multicasting and is usually used in high bandwidth corporate LANs and not
on Internet-based architectures.
This delivery method is useful for training sessions, when there is a specific
timeframe when the audience will view the content. For more information
about using multicasting for streaming your content, see: Stream content
using multicast streaming
l RTP/UDP transport standard is used to stream H.264 video when
unicast or multicast streaming is used. Each viewer retrieves an SDP
file. SDP files can be stored on a streaming server, or opened by a
media player. For multicast, the destination address is where the
broadcast can be viewed.
l MPEG-TS UDP transport standard is used to stream MPEG-4 video
when unicast or multicast streaming is used. Each viewer retrieves a
UDP address to add to their media player.
l MPEG-TS RTP/UDP transport standard is used to stream video when a
single port is used to stream video and audio via unicast or multicast.
Each viewer retrieves a RTP address to add to their media player.
This option can be used to stream video and audio to an IP TV or set top box
playlist.
To stream video outside of your LAN, use a CDN or configure port forwarding on your router. Refer
to your Network Administrator; network configuration is beyond the scope of this guide.
The Streaming feature, used for CDNs and multicast streaming, is available only when the H.264
codec is selected.
Disable (and enable) streams for viewers
When you create a channel it's available by default for viewing by stream viewers who have the stream URL. You
can choose to disable streaming to viewers through the channel's streaming configuration.

Stream content using HTTP or RTSP
The quickest and simplest way to deliver your content is to send the broadcast's URL to your viewers. You can
provide separate URLs for each channel being streamed.
The format of the URL provided to you by the admin interface depends on the method you used to access the
system, either through network discovery using the serial number or IP address.
The system must be accessible on the viewer's LAN for the viewer to use access by serial discovery.
If your system is behind a firewall and you wish to share with remote viewers, you will need to set
up port forwarding on your network. See your IT administrator.
Table 16 URL options

Stream content using UPnP
Using the Universal Plug and Play (UPnP) networking protocol, your VGADVI Recorder Pro can be discovered
and can stream to software and hardware media players, set-top-boxes and Smart TVs with ease. If UPnP is
enabled, the system automatically establishes communication with media players on the network.
UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding (or no audio). You can
only access live streams or recordings that meet these requirements.
For security reasons the default behavior prevents UPnP access to live streams and recorded files.

Stream content using a Content Distribution Network
A Content Delivery Network relies on geo-diverse CDN servers to receive and disperse web content to the CDN
server closest to the user. The closer the server is to the user the faster the content is delivered. Streaming your
content through a CDN allows you to stream any time, anywhere, regardless of the viewing device.
You can test how your content is streamed by sending your content to Epiphan’s CDN or choose one of
Epiphan’s preferred CDN providers http://epiphan.tv/cdn-partners.php.
Stream content to a CDN provider
Publish to any CDN provider that supports incoming streams sent via RTSP announce or RTMP push. Both RTSP
and RTMP can be used for live streaming, however not all CDNs or media servers support both formats. Choose
the streaming format that your CDN or media server supports. Epiphan has tested with the CDN providers
listed here: http://epiphan.tv/cdn-partners.php. Contact your CDN for a list of supported audio codecs and
ensure your configuration uses one of the supported codecs.

When choosing your stream settings it is important to consider the stream content. When streaming fast
moving video it's best to choose a higher bitrate and frame rate versus streaming a slide presentation where
you can save on bandwidth and system processing by lower the bitrate and frame rate. Stream setup is a
matter of balancing quality and system resource usage.
To help you to achieve this balance the following tables list the recommended settings when streaming video

Your VGADVI Recorder Pro can record the output from each channel. (See Recorders for information on
creating multi-track recorders using multiple channels.) Recordings are very robust and crafted so that even in
the case of accidental system shutdown, recording files are closed off and playable.
This section describes the following topics for creating and configuring recordings via the web interface.
l Record a channel via the web interface
l Record with a recorder via the web interface
l Configure the type and length of recording files
l Close the current recording file while recording
l Control recording with a mouse
l Control recording with the big red button
See Control with HTTP Commands and Control with RS-232 / Serial Port for information on controlling
recordings with third party tools. See File Maintenance to learn how to download the recorded files.
Recording can also be controlled via the tablet interface. See Control recording via the tablet
interface.
Recording basics
While recording a channel or recorder, a new file is created each time the maximum time or size limit is met.
Additionally, when recording a multi-channel recorder or a multi-source layout channel, a new file is created if
an additional source is added to the recorder.
Physically removing the source (e.g. unplugging it) or otherwise interrupting the signal to the source does not
affect recording, and the recording will include the configured No Signal image. Recording is stopped if the
channel, or all channels in a recorder, are made inactive by changing the channel configuration to "no source"
via the admin interface.
Each channel that has a source present uses some CPU power to encode the stream. You can avoid CPU
overload by setting up channels you intend to use but setting the source to "No Source" in the admin
interface. When you are ready to use the channel again, simply set the source and all your other configuration
is already set. This doesn't apply for multi-source layout channels which always need at least one source to
keep their configuration settings.
You can choose to create AVI, MP4, MOV or MPEG-TS recordings. See Configure the type and length of
recording files to learn how to change the recorded file type.

c. The system continues to record this channel (and any concurrent recordings) until it is stopped. If
the system runs out of storage space, the oldest recorded file is deleted to make room for the
new recording. The recording is broken into multiple files as defined by the channel
configuration. See Configure the type and length of recording files.
6. To Stop Recording:
a. Click the Stop button on the given channel’s Recording page. The channel number changes to
black next time the web interface is refreshed (by clicking a link or refreshing the page).
Record with a recorder via the web interface
Recorders are stopped and started via their configuration page. Multiple recorders and channel recordings can
occur concurrently.
A new recording file is generated each time a configured source in the recorder comes online. For example if
the recorder has two configured sources but when the recording starts and only one source is active, it will
start a single-track recording. When a second source starts sending signal, the first recording file is closed and
a new multi-track file is opened. If a source that is being recorded becomes inactive, the recorder continues to
record the source with the no signal image.
The number of active sources is displayed above the recording stop/start buttons during recording.
To start and stop recorder:
1. Connect to the admin interface using your preferred connection mechanism. SeeConnect to the Admin
Interface.

Configure the type and length of recording files
By default, recorders and channels record to AVI files. When the recording reaches 30 minutes in length or a
file size of 500 MB (whichever occurs first), the system closes the current recording file and opens a new one.
This is done seamlessly with no loss in recorded data.
You may find it useful to have recordings divided this way for ease of download, but you may also want to
change the recording limits to be larger or smaller to meet your individual situation.
Additionally you can configure the prefix for all recordings (the suffix is the date and time of the recording) and
you can exclude a channel or recorder’s recordings from automatic upload.
To change the recording configuration:

l FAT16
l FAT32
l XFS
l EXT2
l EXT3
l EXT4
Only the first attached USB drive is used for automatic file upload. If more than one USB drive is
attached before system power up, behavior is unpredictable.
File transfer to a USB drive occurs in one of the following ways. This section describes the procedures.
l AFU to a USB drive (part 2 of 3)
l One-time copy/move of all recorded files to USB drive
l Manually copy recorded files to USB drive

Using a software or hardware media player, you can browse for files or streams with Universal Plug and Play
(UPnP). UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding (or no audio). You
can only access live streams or recordings that meet these requirements.
For security reasons the default behavior prevents UPnP access to live streams and recorded files.
To enable UPnP, see Stream content using UPnP
202
VGADVI Recorder Pro User Guide
6-1 View your video
Some players cannot access the stream or saved recordings if a viewer password is set. If needed,
see Removing User Passwords to clear the viewer password.
When browsing via UPnP your VGADVI Recorder Pro is displayed by the server name you set, or it's product
serial number.
For example, when browsing from a Windows computer, you will see a list of media devices that includes the
VGADVI Recorder Pro:
Live Streams
When you open the device from Windows Media Player, you'll see a list of the available channels you can stream
under the Videos tab. The channel names are the same as they are in the admin interface. From other digital
media players, the channel list can be under a Live Streams folder.
With Windows Media Player, double click to open any channel and press Play to start the stream. Using your
digital media player, select a live stream and press play.
Recorded Files
Recorded files are shown in the Recorded Files folder. Files are organized by the channel or recorder from
which they were recorded. Windows Media Player shows the recorder files side by side with the channels and
other digital media players show the recorded files in a file tree format, see below.
203
VGADVI Recorder Pro User Guide

UPnP can also be used to directly play a recording to the digital media player, or to set a media player to
automatically play a particular live stream after reboot of the VGADVI Recorder Pro. See Stream content using
UPnP and Auto-restart playback to a UPnP device.
Viewing with Session Announcement Protocol (SAP)
When SAP Announce is configured for a stream that uses UDP streaming, the stream is advertised over the
local network. Local viewers can view the stream using a software or hardware media player. Viewers are
presented with a list of available channels, similar to a television menu. Viewers need only click on a stream and
the video is streamed to their desktop, mobile or tablet. To configure SAP announce, go to Stream content
using multicast streaming.
Your stream is advertised by the metadata title, if one was configured under Branding, otherwise it is identified
by it's channel identifier. For a description of how to set the metadata, refer to Add your logo and company
information to your channel.
When browsing from a VLC media player, streams are advertised by their channel identifier and are organized
by the group name. When browsing from an XBMC media player, streams are advertised by the stream's
metadata title, if configured, otherwise streams are advertised by their channel identifier.
1. Ensure the stream has SAP announcement enabled, otherwise it is not advertised in the media player's
playlist.
2. Ensure the SAP announcement IP is a multicast IP address.
3.
Some media players, for example Exterity receivers, listen for SAP announcements on a
specific multicast address 239.255.255.255. If your audience is using Exterity to view your
stream, you must change the SAP announcement IP address to 239.255.255.255.
4. Launch a media player. The following steps are based on a VLC media player and may be different for
other media players.
5. Click View from the menu; a drop-down menu opens.
6. Select Playlist. A Playlist window opens. The right-hand panel indicates the playlist is empty.
7. From the side menu, click Network streams (SAP). The playlist is populated with all streams in your
network that are SAP announcement enabled. If you specified a Group Name when you configured the
publish stream the stream will be listed in folder identified by the group name.
In the example below, two streams D2P83658.vga and D2P83658.video are organized in a folder by their group
name.

7-7 Storage Disk Maintenance
7-7 Storage Disk Maintenance
Your VGADVI Recorder Pro is equipped with one or more hard drives for storage of recordings. Occasionally,
maintenance is required for these disks. This section describes procedures for the following topics:
l Check disk storage space
l Schedule disk check
l Perform disk check
l Rebuild or replace storage disks
l Verify RAID storage
l Read data from removed storage disks
Check disk storage space
VGADVI Recorder Pro has a finite amount of storage This storage space holds a lot of recordings, but it can get
full. It’s a good idea to monitor your current disk usage.
If available storage is low, consider removing some unneeded recordings or setting up an automatic file
transfer with deletion after transfer. See File Maintenance and File and recording transfer.
Disk space can also be checked via the tablet interface. See Verify disk space via the tablet
interface.
To check disk storage space:
1. Connect to the admin interface using your preferred connection mechanism. SeeConnect to the Admin
Interface.
2. Login as admin or operator.
3. Check the Internal Storage section at the bottom of the menu column. The bar will be mostly green if
there is lots of space left, or mostly red if storage space is nearly full.

VGADVI Recorder Pro User Guide
7-7 Storage Disk Maintenance
4. If available storage is low, take action to remove files as discussed in File Maintenance and File and
recording transfer.
Schedule disk check
A disk maintenance schedule is used to check the system storage drives for errors. Two values are supplied,
one to specify the number of system restarts that should occur before disk check, and the second to specify
the number of months before performing a disk check. The disk check happens based on whichever event
occurs first.
For example, the restart setting is set to 50 and the months setting is set to 6. If six months pass and less than
50 restarts happened, a disk check will occur on the next restart. However if you do 50 restarts in one month,
the disk check will happen after the fiftieth restart.
Disk check occurs during start up and can cause a lengthy delay in starting up the system.
To set the disk check schedule:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Disk Check link in the Configuration menu; the disk maintenance page opens.
4. Set the number of restarts to occur before the next check. Set to 0 if you don’t want to force a disk
check after a specific number of restarts.
5. Set the number of months to pass before the next check. Set to 0 if you don’t want to force a disk
check after a specific number of months.
6. Click Save.
Perform disk check
A disk maintenance schedule is used to periodically check the system storage drives for errors. If you prefer,
you can run the disk check manually at a time that is convenient for you.
Running the disk check manually resets the timers for the scheduled disk check (i.e. next check won’t happen
automatically until either the number of restarts or months passes).
If the system is recording when you start a disk check, it will stop recording and resume after the
check is complete. Frames presented during the disk check are not part of any recording.
To start a manual disk check:

Rebuild or replace storage disks
The rackmount VGADVI Recorder Pro can be optionally configured with storage configured in a RAID array.
Periodically you may wish to clean the RAID array to start from scratch, or you may want to introduce new disks
in place of the old ones.
When working with RAID arrays it is important to keep the disks in sets that contain the same data so the RAID
will continue to perform. For that reason you should name your disk sets, i.e. set A, set B, etc.

Read data from removed storage disks
The latest hardware refresh for VGADVI Recorder Pro includes removable disk drives. VGADVI Recorder Pro
storage drives use an ext4 file system and can only be read with a computer running Linux.
These steps describe how to read the recorded files from the removable storage drives using Ubuntu.
237
VGADVI Recorder Pro User Guide
7-7 Storage Disk Maintenance
Depending on your exact version of Linux, the steps you follow may differ slightly from the steps
below.
To read the recorded files:
1. Install Linux on a workstation where the drives will be installed (Ubuntu or Debian are recommended.
RedHat/CentOS/Fedora are also supported).
2. Confirm mdadm tool is installed, if not, install it. For Ubuntu/Debian use apt-get, for RH/CentOS use
yum.
3. Turn off the workstation and connect the storage drives (if using RAID 1 you can attach just one drive).
4. Start the workstation.
5. If only one drive of a RAID 1 set is connected:
a. Open a terminal window and enter the following in the command line to determine the name of
the disk:
sudo fdisk -l
b. Issue this command to build the disk:
(In the example, the disk name is /dev/sbd1. Your disk name may be different.)
sudo mdadm —assemble /dev/md0 /dev/sdb1
c. The following message appears:
mdadm: /dev/md0 has been started with 1 drive (out of 2).
6. Verify that RAID is started. At the command line, enter:
sudo mdadm -D /dev/md0
7. Verify that the output is similar to this, with the disk in a clean state and the correct RAID level indicated:
(Only one disk is used in the example. If you are using multiple disks, the output will be a bit different.)
/dev/md0:

in the command line, substituting the name of your device instead of /dev/md0, if needed:
sudo mkdir /mnt/raid; sudo mount /dev/md0 /mnt/raid
9. If using a graphical interface in Linux, browse to the location of the drive in File Manager. Otherwise, use
a terminal window to change directories (cd) into the drive.
10. Browse to the /mnt/raid folder (or the appropriate folder name) in File Manager.
11. All recordings are kept in a folder hierarchy matching the channels and recorders you created via the
web interface. Channels are listed by their channel number as video<channel number> (i.e. video1 for
channel 1) and recorders are listed by their recorder number with the videom prefix (i.e. videom2 for
recorder 2).

7-8 Control with RS-232 / Serial Port
VGADVI Recorder Pro presents an RS-232 / serial port control interface for integration with existing control
room and board room equipment. This section covers the following topics:
l Connect and configure the RS-232 cable
l Control the VGADVI Recorder Pro with RS-232
l RS-232 / Serial port command examples
Connect and configure the RS-232 cable
To connect your control equipment to the VGADVI Recorder Pro you will need a standard RS-232 null-modem
cable and a USB to RS-232 serial adapter cable. Adapter cables are not included with the VGADVI Recorder Pro.
Only certain adapter chipsets are supported, Epiphan recommends this adapter cable from Startech.
To connect the serial port cable:
1. Attach the null modem cable to the control interface.
2. Connect the null modem cable to the serial port on the back of the system.
The only configuration available for the serial port is flow control. Flow control changes the rate of data
transfer over the cable. Some communication settings are static and cannot be changed. The static settings
are:
l Baud rate set at 19200
l Parity set to none
l Stop bits set to one
To configure serial port flow control:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Serial Port link in the Configuration menu; the serial port configuration page opens.
4. Select Hardware, Software, or None from the drop-down menu. Refer to the table below for a
description of the options.
240
VGADVI Recorder Pro User Guide
7-8 Control with RS-232 / Serial Port
Table 30 Serial Port Flow Control Options
Label
Description / Options
Hardware
A hardware handshake mechanism is used for flow control. This is also called RTS / CTS flow
control. Select this when your control terminal requires it (see control terminal manual).
Software
A software handshake that uses XON/XOFF characters to control the flow of data. Select this
when your control terminal requires it (see control terminal manual).
None
No flow control is used. Only select this if your control terminal requires it (see control
terminal manual).
5. Click Apply.
Control the VGADVI Recorder Pro with RS-232
You can use the null-modem cable and your control terminal software to issue commands to the VGADVI
Recorder Pro such as when to start or stop recording, or to retrieve or set the value for various settings.
Each command sent to the VGADVI Recorder Pro via RS 232 must be terminated with a line feed (LF) character (ASCII code 10). Your software may need to be configured to add the line feed to
each command.
Some commands require a channel or recorder name as an argument. In those commands, the channel or
recorder name is separated from the command name by a period, as shown in the table. The channel name
value can be either the name or the index of the recorder or channel. Use of the index is recommended.
A channel's index is found by looking at the Channels list in the web interface. In the screen capture below, the
channel with index 1 is currently recording (it's index number is red). To address this channel via RS-232
commands, use the index 1.
241
VGADVI Recorder Pro User Guide
7-8 Control with RS-232 / Serial Port
For commands requiring a recorder index, determine your recorder's index by combining the recorder's
number with the prefix m. In the example below, the second recorder's index is 2. To access this recorder via
RS232 commands, use the index m2.
The table describes the RS-232 commands supported by the VGADVI Recorder Pro.

7-9 Control with HTTP Commands
7-9 Control with HTTP Commands
VGADVI Recorder Pro has an HTTP API interface for configuration and control by a third party application or
with a script that sends commands to the system as a series of URLs. This section covers the following topics:
l HTTP command syntax
l HTTP command examples
HTTP command syntax
Control of the VGADVI Recorder Pro by HTTP is done by sending commands to one of two URLs and specifying
the target configuration item. Syntax for the get and set commands follows.
Many commands require a channel or recorder index as an argument. A channel's index is found by looking at
the Channels list in the web interface. In the screen capture below, the channel with index 1 is currently
recording (it's index number is red). To address this channel via http commands, use the index channel1.
For commands requiring a recorder index, determine your recorder's index by combining the recorder's
number with the prefix channelm. In the example below, the second recorder's index is 2. To access this
recorder via http commands, use the index channelm2.
To Get configuration settings:
246
VGADVI Recorder Pro User Guide
7-9 Control with HTTP Commands
http://<address>/admin/channel<N>/get_params.cgi?key
(or for recorders, add 'm' before the recorder number, i.e. channelm1 for recorder 1)
http://<address>/admin/channelm<N>/get_params.cgi?key
To Set configuration settings:
http://<address>/admin/channel<N>/set_params.cgi?key=value
(or for recorders, add 'm' before the recorder number, i.e. channelm1 for recorder 1)
http://<address>/admin/channelm<N>/get_params.cgi?key
Where <address> is the IP address of the system, channel<N> is the channel number (i.e. channel2 for channel
number two), channelm2 for recorder two, key is the key for the configuration item being checked or changed
(see the list in Configuration Keys for Third Party APIs ), and value is the value to set for the configuration item.
Multiple Requests at Once
You can include multiple key/value pairs in a single command by separating the statements with &.
For example, the key for product name is product_name and the key for firmware version is firmware_version.
To send a request for both the product name and the firmware version, use the following command:
http://<address>/admin/channel1/get_params.cgi?product_name&firmware_version
Or, to turnoff publishing (set to 0) and set the bitrate (vbitrate) to 256,000:
http://<address>/admin/channel1/set_params.cgi?publish_type=0&vbitrate=256K
Third party applications like wget
If you’re using a third party application like wget to send commands to the system, always include the admin
username and password when viewing or setting configuration items.
The syntax for wget commands is shown below. Specify your system’s IP address, password and the key(s) or
value(s) you wish to query. Note your system may require use of single quotes around the password to handle
special characters such as exclamation marks.
get_param using wget:

Release 3.14.1 Features
Hardware Refresh
SDI source support
Our newest line of VGADVI Recorder Pro systems now capture, encode, stream and record even more HD content! In
addition to the DVI-I ports and S-Video ports found on previous models, VGADVI Recorder Pro now has SDI ports. The
new SDI ports support capture of SDI video and audio.
HDMI audio support
Release 3.14.1 adds the ability to capture audio from non-HDCP protected HDMI sources on new systems built with
updated hardware. Simply add the HDMI source to your configured channel to include audio. (Older models cannot
capture HDMI audio. If your system has SDI ports, it supports HDMI audio.)
New Encoding / Streaming Features
48 kHz audio support
For greater flexibility and improved audio quality from digital sources, VGADVI Recorder Pro now supports 48 kHz audio
sampling.
Hardware acceleration for H.264 encoding
VGADVI Recorder Pro is capable of capturing and encoding up to 300 frames per second of HD video thanks to the
addition of hardware accelerated H.264 encoding. H.264 with hardware encoding is the default for new all channels,
but you may still use software encoding if needed for compatibility reasons.
Simplified H.264 video encoding presets
To make channel configuration even easier, H.264 encoding now has only two presets: hardware accelerated or
software encoding. These selections offer the best video capture possible while maintaining excellent performance
throughput.
Configurable EDID
Some situations require you to configure your VGADVI Recorder Proso that it describes it's extended display
identification data (EDID) a particular way for maximum compatibility with your source. Starting with release 3.14.1, you
can upload custom EDIDs for VGA and DVI/HDMI sources, making VGADVI Recorder Pro report its video capabilities
exactly as you need.
New Recording Features
MP4 support
Recording your AV stream is even more flexible with the addition of MP4 recording support. Select from MOV, AVI, MP4
or MPEG-TS recording.
Other Changes
Improved channel configuration menu
Improvements to the channel configuration menu mean it's easier than ever to configure your channel. Sections have
been renamed and ordered in a logical sequence for channel setup. Start by selecting Sources, then configure
Encoding and Branding. Lastly setup Streaming and Recording.
Release 3.12 Features
New Streaming Features
RTMP live streaming
Your VGADVI Recorder Pro can now stream live video to a content delivery network using Real Time Messaging
Protocol (RTMP). In addition to providing high performance streaming of audio and video, when you stream your
content using RTMP, you reduce system resource usage as well as enhance your viewer's experience.
When setting your CDN, you now have a choice between streaming with RTSP announcement or RTMP push. Both
RTSP and RTMP can be used for live streaming, however not all CDNs or media servers support both formats.
See Stream your video.
SAP Announce
Your VGADVI Recorder Pro allows you to advertise your stream over a local network using SAP Announce. To use this
feature, your stream must be setup to use UDP streaming. Local viewers can view the stream using a software or
hardware media player. Viewers are presented with a list of available channels, similar to a television listing. Viewers
need only click on a stream or channel and the video is streamed to their desktop, mobile or tablet.
See Stream content using multicast streaming.
Layout and Branding Improvements
Enhanced layout for multiple source channels
You can customize your output stream by adding a customized background image to your multiple source channel.
You can create a background that is consistent with your corporate branding and easily apply the background to your
video stream.
See Add a customized background to a multiple source channel
Data Redundancy and Fault Tolerance Improvements
RAID 10 support
For systems configured with at least 4 storage disks, RAID 10 is now supported.
Enhanced Internal Storage Diagnostics
You can now check if storage disks are configured for RAID, the RAID configuration level, and RAID array status.
Release 3.11 Features
Recording Features
Multiple multi-track, multi-channel recorders
Save time in post-processing by specifying exactly which channels are included in a recording or choose to create an allin-one recorder to include all channels in a single multi-track file. Include the same channel in multiple recordings
wherever needed. Record all-in-one videos simultaneously with other needed recordings.
See Recorders.
Multiple audio sources
The VGADVI Recorder Pro now supports one audio input per DVI input in addition to the system's main line-in or
microphone. No need to pre-mix audio before routing it to the device for recording.
To support this change, the Audio menu tab has been removed and audio sources are now listed under the Sources
section. Audio inputs are named according to the capture card on which they reside. I.e. the audio input next to the
DVI input D2P83659.vga is called D2P83659_analog. Audio inputs from the server's main board have no product serial
number and are prefixed by audio.
Audio source mixing
Recorders and channels can contain multiple audio sources, resulting in any number of configurations of single source
or combined audio output. Incoming audio signals are mixed in software and levels are reduced proportionally to avoid
audio clipping.
The new mobile interface displays an overall audio input meter.
Precision time protocol (PTP) synchronization
Ensuring multiple sources are synchronized and time-stamped precisely is easier than ever. with support for PTP time
synchronization.
See Configure Date and Time.
Custom recording file names
Starting with release 3.11.0, you can customize the prefix used for recorded files. Use this to identify files being autouploaded from various rooms at a conference, or to keep track of which source is being recorded.
See Configure the type and length of recording files
Streaming Features
AAC audio codec
AAC is now supported for audio encoding. The system uses simplest and most commonly used AAC audio codec
profile: Low Complexity (LC). Mono audio only.
MPEG-TS streaming for IPTV
VGADVI Recorder Pro now supports MPEG-TS streaming over RTP/UPD and UDP for easy integration with IPTVs. Simply
provide the IPTV's or IPTV gateway's IP address in the channel's publishing configuration menu to enable transmission
of the MPEG-TS stream.
See Choose a codec to maximize your stream quality.
Universal plug and play (UPnP) support for streaming media players
Your system can now be discovered and streamed through software and hardware media players, set-top-boxes and
Smart TVs with ease. UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding.
See Stream content using UPnP.
Layout and Branding Improvements
Visual stream feedback and simplified picture-in-picture layout
Video source previews are now available for each input. The preview function takes a single frame from the source every
three seconds and is visible from the Frame Grabber configuration pages.
If a given input has no signal a No Signal message is displayed. Previews are also visible via the new tablet interface. See
Configure a video source and Mobile / Tablet Operator Interface for details.
Creating multi-source layouts has never been easier! The new layout configuration screen shows you a live preview of
your configuration. Each added source can be clicked and dragged to a new location.
See Create a multi-source layout.
Stream branding and custom no signal image
You can customize output streams by adding your company logo or other overlay image to the encoded stream and by
providing a custom image to display prior to broadcast or other times when a source has no signal. Images in JPEG and
PNG format are accepted. Image transparency is not currently supported.
Preservation of source aspect ratio
A new feature, enabled by default, makes sure that the aspect ratio of input signals is preserved when encoded and
streamed. If an input video signal doesn't match the encoding ratio, a matte is applied and bars are visible at the sides
or top and bottom of the encoded stream. The color of the matte is customizable.
Customizable stream background color (matte)
You can select the matte color displayed when a layout results in pillarbox or letterbox effect due to input aspect ratio
preservation or when a multi-view layout has areas with no video.
Personalized stream metadata
Each channel has its own content metadata that you can configure to ensure proper attribution, content description
and copyright information is sent with your audio/video stream.
Mobile and Tablet Features
Introducing the mobile / tablet operator interface
Use your mobile device or tablet for confidence monitoring of channels, streams and audio levels. You can now start
and stop recordings from an interface designed for a touch-screen device. Point your smartphone or tablet to
http://<system IP address>/admin/m.
See Mobile / Tablet Operator Interface.
Discovery of Epiphan devices
Use the new Epiphan Connect application on Android and iOS as an alternative to the desktop based discovery utility.
The application has built-in support for opening the tablet operator interface and can be configured to automatically
open the tablet interface if connected to the VGADVI Recorder Pro by USB.
Mobile tethering
Release 3.11.0 introduces the option to use mobile tethering for recording control, confidence monitoring and mobile
network file transfers. Configure mobile data tethering and turn on automatic file uploads to automatically transfer
files to a remote site using the public mobile network. Alternatively, choose to tether for confidence monitoring and
recording control only.
Configure the VGADVI Recorder Pro to use no mobile data, to use Ethernet normally and switch to mobile data if the
Ethernet becomes unavailable, or to mobile data as the preferred transmission method.
Other Improvements:
l Based on the video encoder type, source resolution and stream frame size, the device now automatically
calculates a suggested bitrate that provides the best performance and quality trade off. Examples for H.264:
l 640×480, 15 fps, - 1.4 Mbps
l 1280×720, 20 fps - 2.6Mbps
l 1920×1080, 30 fps - 6.5 Mbps
l When using auto-file upload, you can choose to exclude specific channels from upload. This is useful if you
have one channel used for lower-quality streaming and another for higher-quality recording. Save space on your
network server by not uploading the lower-quality recordings automatically.
l You can now select what happens when you insert a USB drive: nothing; a one-time copy or transfer to the
drive; a manual copy or transfer to the drive; or automatic continuous copy or transfer of recorded files to the
drive.
l As of 3.11.0, you can configure the system to automatically upload recorded files to an attached USB drive.
Choose to either have it work the same way as uploading via FTP, CIFS, or RSYNC; or as a one-time download of
all the recordings on the system. Auto-file upload to USB drives supports storing recordings from each channel
in its own subfolder. See Upload to an external USB drive
l Each audio and video input now indicates which channel(s) are using it, or if the input is not used. This can help
you determine if you have any inputs that are not being streamed or to assess which channels would be
affected by downtime for a given input.
l The HTTP Live Streaming (HLS) link is now displayed on the Channel Status page. HLS allows access to live
streams over the standard HTTP port 80, making able to traverse firewalls and proxies that are able access the
internet for other HTTP traffic.
l MPEG-TS format recording. This robust encoding mechanism has no index or trailer structures making it the
most fault tolerant format supported by the VGADVI Recorder Pro. MPEG-TS files are ready for streaming over
HTTP, RTP and UDP.
l Enjoy the new live stream resume feature to ensure a digital media player automatically gets the stream
when it becomes available after the VGADVI Recorder Pro restarts. Simply choose a stream and the UPnPenabled media player to control. See Stream content using UPnP.
l Direct your digital media player to play a recorded MPEG-TS files from the systeme. Browse to the Files
Archive and press the play button to choose from accessible uPnP media players. SeeStream content using UPnP
l Fast encoding has been removed and replaced with video encoding presets. New values are Default, High
Quality, and High Speed.
l H.263 (an older Flash implementation) is replaced with MPEG-4. As of Flash Player 9, update 3 (in December
2007), Flash supports H.264 encoding. If H.264 does not suit your needs, you can still support older players with
the MPEG-4 codec. The exact codec supported is Microsoft MPEG-4 version 2.
