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 content using HTTP or RTSP.
SAP Announce
Your 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.

Quick Start
This section helps you get up and running quickly with your Lecture Recorder x2:
l Step 1: Physical setup and power on
l Step 2: Confirm signals from input sources
l Step 3: Admin discovery and login
l Step 4: Setup the video source
l Step 5: Configure the channel
l Step 6: Record 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 (if needed)
l optionally, an audio source such as a microphone or the headphone jack from a laptop (note that the audio
signal sent over HDMI cables is not supported)
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)
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 ports.
1. Turn on your HD source and connect the output cable to the DVI-I input port on the front of the device.
2. (optional) Attach a 3.5 mm audio cable from your audio source to the system’s audio input port.
3. If your network connection provides power over Ethernet:
a. Connect the Ethernet cable to the system.
b. Connect the Ethernet cable to your network.
If your network connection does not provide power over Ethernet:
a. Connect the PoE injector into a grounded AC power source.
b. Connect an Ethernet cable from the Ethernet switch port on your network to the RJ-45 connector
(labeled In) on the PoE injector.
c. Connect an Ethernet cable from the RJ-45 connector (labeled Out) from the PoE injector to the RJ-45
Ethernet port on the back panel of the Lecture Recorder x2.
4. Wait for the system to complete the power up sequence. The green power LED is illuminated when boot up is
complete.
Step 2: Confirm signals from input sources
Once the Lecture Recorder x2 is powered up, you can confirm that signals from input sources are received by the
device.
1. To ensure an input source is properly connected to the DVI input port, connect a monitor to the DVI output
port on the Lecture Recorder x2.
2. View the monitor to confirm a signal is sent to the DVI input port.
3. To confirm high quality data is captured from an S-video input source, connect the source to an S-video or
composite receiver, such as a TV or monitor before connecting to the Lecture Recorder x2 and confirm that a
high quality signal is generated.
4. To ensure an audio signal is sent to the Lecture Recorder x2, connect a speaker or headset to the audio output
port and listen to the captured audio.
Now you are ready to capture, record and stream.
Step 3: Admin discovery and login
The Lecture Recorder x2 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 may not know the IP address of the device.
The steps below use DNS-based service discovery (a type of zero-configuration networking) to access the device.
Depending on the operating system on your admin computer you may need to install some software before you can
use DNS-based discovery.
Table 5 Installing Bonjour Print Services
System
Action Needed
Microsoft Windows
You must install Bonjour Print Services:
1. Use the following URL - http://support.apple.com/kb/DL999
2. Click Download.
3. Follow the system prompts to download and install the application.
Mac OS X
The Bonjour software used for service discovery is built into the Mac OS. No special actions are
needed.
Linux
The Avahi implementation used for DNS-based discovery is shipped with most Linux
distributions. If necessary, check with your administrator to ensure you have the Avahi
package installed.
This quick start is meant for systems that support DHCP and DNS, however if your system does not support
either protocol, refer to Connect to the Admin Interface for other discovery methods. Return here when
prompted for the web interface user name and password.
You are able to access the system's web interface on the local network by specifying its serial number in a web browser
on your admin computer.
1. Find the system’s serial number. It is printed on a sticker on the back of the device.
2. Type the following string into the address bar of your web browser on your admin computer and press Enter.
(<serial> is the serial number of your Lecture Recorder x2):
http://<serial>.local/admin
For example: http://3D24A1.local/admin
3. Enter the user name and password then click OK. The administrative user is ‘admin’. Initially no password is set.
To set a password follow the procedure outlined in Setting and Changing User Passwords.
4. Optionally, navigate to the Network link under the Configuration heading and note the IP address of the
system.
Step 4: Setup the video source
When a source device, such as a camera or tablet is connected to an input port, the Lecture Recorder x2 automatically
recognizes the source and adds the source to the Stream Setup menu in the Web Interface.
1. From the web interface, click on the Info page; the info page opens displaying the live stream and the stream
URL. This is the link you can share with your viewer to view the live broadcast.
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 5: Configure the channel
Now that you confirmed the system detected your source and you are satisfied with the captured image, it’s time to
configure a channel to share the captured image with your streaming users and prepare the source for recording.
Review and configure the channel:
1. From the web interface, click Stream Setup. The Steam Setup page opens displaying configuration settings for
DVI and S-Video channels.
2. 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 automatically calculated based on the resolution of the input signal. Raising this value uses
more system processing power and more bandwidth.
You may now optionally add audio to your channel:
3. Scroll to the bottom of the Stream Setup page and ensure the Enable audio checkbox is enabled (enabled by
default) for the audio source to which you connected your 3.5 mm audio cable.
4. Leave the default PCM 22KHz format and audio bitrate.
5. Click Apply.
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 viewers on your local area network (LAN). Depending on your
internet connection and upstream bandwidth, you may need to adjust the video bitrate down before sharing over the
internet.
Step 6: Record the stream
The device is set up and streaming. This may be all you need, but if you like, you can also record the stream.
To record the stream:
1. From the web interface, click the red Start button at the top of the menu; the text at the top of the screen
changes to indicate the recording is starting, then indicates the length of time since the recording started.
2. Click the black Stop button; the recorder stops.
3. To view the result, click Recorded Files; the recorded files page loads and a file list appears that displays your
newly recorded stream snippet.
4. Click the file name to download and view your recording.
What’s Next?
Now that you have a source setup and ready to stream, you can fine-tune the system to your exact requirements. You
can look at topics such as:
l Customize your channel
l Stream your video
l File and Recording Transfer
l User Administration
When you have completed system tuning, make sure to back up the device configuration using the procedure
described in:
l Save and Restore Device Configuration
Refer to the table of contents for a complete list of the topics covered.

device, 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.
For example if your device 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 device. 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 device you can specify the range of
boardroom IP addresses rather than needing to type in each individual address. The allow list looks as follows:
38
Lecture Recorder x2 User Guide
1-5 Restrict Viewers by IP Address
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 device 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:
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:
39
Lecture Recorder x2 User Guide
1-5 Restrict Viewers by IP Address
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

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

Video is too bright, too dark or washed out
If the video from the source is too light, too dark or washed out, use the offset and gain controls together to
optimize image quality. Increasing the gain amplifies weak signals but also increases noise, you must balance
offset and gain values to achieve the best quality image.
Adjust these settings by the smallest values possible; compensate for a large change to one by making a large
change to the other. Setting both offset and gain to high values can result in poor video quality.

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
Interface.
2. Login as admin.

Force the video source to use a specific resolution
Extended display identification data (EDID) is data provided by a video display device (usually a monitor) to
describe its capabilities to a video source. 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.
When you connect the VGADVI to a video source, the video source sees the device as a monitor. Just like a
monitor, the VGADVI contains the EDID that is used by the video source to determine the video signal to send.
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 video source to use a specific resolution.
The uploaded EDID is permanently installed on your VGADVI and will always share this EDID with the video
input source.

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
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 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

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, click Stream Setup; a Stream setup page opens.
4. Click Video encoding preset to define how a video stream is encoded. Choose one of the following:
Value
Description
High quality
Choose this option when you are streaming content such as slides or slow moving
video.

Default
Choose this option when video is viewed for broadcast and disk storage
applications, particularly for high definition television application such as Blu-ray
disk storage format and HDTV broadcast service.
Video encoding profile and preset can be set when H.264 codec is selected.
6. Check the check box for Enhanced compatibility mode (h.264 slicing for RTP) to provide operating
stability when the video and audio stream are not supported by the viewer’s equipment. When this
feature is enabled, each frame is sub divided into one or more slices. Each slice is self-contained, all
information for decoding is available within the slice. This is valuable when packet size exceeds the
maximum allowable amount. Therefore losing a slice will not impact the entire frame.
Packet slicing adds to overhead and impacts compression efficiency. A value can be set
when H.264 codec is selected.
7. Set the Rate Control mode when H.264 and MPEG4 codecs are set. The values define how strictly the
codec adheres to the specified bitrate. Choose one of the following options from the Rate control mode
drop-down menu.

Lecture Recorder x2 User Guide
3-2 Fine-tune channel configuration
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.
The Lecture Recorder x2 conveniently provides a list of common aspect ratios and different frame sizes at each
ratio on the Stream Setup 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 rather than leaving the video at a native
resolution. Although you can change the resolution at the Lecture Recorder x2 level, it is less of a
burden on your system resources if you can change the resolution at the source level. However if
that is not feasible, you can download an EDID to the Lecture Recorder x2 to force the source to
send a specific resolution. See Force the video source to use a specific resolution .
To change the frame size of your video, follow the steps below.
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Click Stream Setup; the stream setup page opens.
4. Scroll to the frame size parameter.
5. Deselect Use current signal resolution as frame size, if it is selected.
68
Lecture Recorder x2 User Guide
3-2 Fine-tune channel configuration
6. Choose a resolution from the links on the right, or type a frame size into the Frame size fields.
7. Click Apply.
The final frame size can be larger when Picture in Picture layouts are used.
Control the matte (black bars) in the video output
By default, the Lecture Recorder x2 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 Stream Setup 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)
Borders are added to the top and bottom of the image to preserve the wider ratio of the input.
69
Lecture Recorder x2 User Guide
3-2 Fine-tune channel configuration
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.
The left and right side border are not guaranteed to be of equal width.
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.
Match the output frame size to the aspect ratio of the source signal
To change the output frame size to match the aspect ratio of the source:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Click the channel's Stream Setup; the stream setup page opens.
4. Scroll to the frame size parameter.
5. The simplest option is to select Use current signal resolution as frame size and click Apply. You can
alternatively select it briefly to note the current video signal resolution, then deselect it and follow the
steps below.
70
Lecture Recorder x2 User Guide
3-2 Fine-tune channel configuration
6. Look for the source aspect ratio in the list of aspect ratios provided.
a. If the source resolution is on the list, choose another resolution on the same line (i.e. with the
same aspect ratio).
b. If the source resolution is not on the list, use a calculator to get a factor of the source resolution
and enter it in the Frame size fields.
7. Click Apply.
Stretch the image
To remove the matte (black bars) by stretching the image to fit your output frame size:
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, click Stream Setup; the stream setup page opens.
4. Deselect Keep aspect ratio.
5. Click Apply.
71
Lecture Recorder x2 User Guide
3-2 Fine-tune channel configuration
Unstretch the output video
By default, the Lecture Recorder x2 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. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, click Stream Setup; the stream setup page opens.
4. Select Keep aspect ratio.
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 (the maximum is 30). 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.
72

4. Enter a value in the Limit frame rate field.
5. Click Apply.
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:
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, click Stream setup; a Stream setup page opens.
4. Scroll to the Key frame interval drop-down menu. Choose the number of seconds before the system
streams a key frame.

Lecture Recorder x2 is ready to stream content as soon as it is has power
and an input signal. 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.
RTSP
Quickly stream content to viewers. No set up is required. The Lecture
Recorder x2 is ready to stream content as soon as it has power and an input
signal. 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

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.

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
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 Publish Stream feature is available when the H.264 codec is set.
Retrieve stream URLs
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. Alternatively, one URL can be provided that includes
all streams from all input sources. The format of the URL depends on the method you used to access the device,
either through network discovery using the serial number or IP address.

Stream content using UPnP
Using the Universal Plug and Play (UPnP) networking protocol, your Lecture Recorder x2 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 device 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.
This section covers the following topics:
l Enable UPnP
l Disable UPnP
l Stream your video
l Auto-restart playback to a UPnP Device
l Change UPnP device name
Some players will not be able to access the stream or saved recordings if a view password is set. If
needed, see Removing User Passwords to clear the viewer password.
The topics in this chapter include how to enable and disable UPnP and how to control media players from the
Lecture Recorder x2. To choose recordings or live streams from your media player, see Viewing with UPnP .
Enable UPnP
Enable UPnP to allow digital media players on the network to browse for media or live streams from your
device.
Streams and MPEG-TS recorded files must use the supported codecs: H.264 with MP3 or AAC
audio. Having a viewer password could prevent the ability to use UPnP.
To enable UPnP:

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

Recording basics
While recording a channel, a new file is created each time the maximum time or size limit is met. When
configuring these limits you can choose to have recording stop when there is no signal present in the sources.
See Configure the type and length of recording files. This can be very useful to save disk space, but can cause
multiple files for a single session if the session involves switching presenters or input types.
Control recording via the web interface
To start and stop recording:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin or operator.
3. To Start Recording:
a. Click the red Start button in the Recorder Status section; the recording starts and a timer
indicates how long it has been recording.

b. The device continues to record until it is stopped or the device runs out of storage space. The
recording is broken into multiple files as needed.
4. To Stop Recording:
a. Click the Stop button in the Recorder status section.
Configure the type and length of recording files
By default recordings are saved as AVI files. When the recording reaches 10 minutes in length or a file size of
100 MB (whichever occurs first), the device 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:

5. Press Play. The stream is played in the media player window.
Viewing with UPnP
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
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 Lecture Recorder x2 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
Lecture Recorder x2:
140
Lecture Recorder x2 User Guide
6-1 View your video
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 name is VGADVI. 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.
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 Lecture Recorder x2. 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
141
Lecture Recorder x2 User Guide
6-1 View your video
the video is streamed to their desktop, mobile or tablet. To configure SAP announce, go to Stream content
using multicast streaming.
Your Lecture Recorder x2 is advertised by the metadata title, if one was configured under Stream Branding,
otherwise it is identified by it's product serial number. 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 product serial number 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 product serial number.
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 are organized in a folder by their group name.

7-6 Storage Disk Maintenance
7-6 Storage Disk Maintenance
Your Lecture Recorder x2 is equipped with a solid-state storage drive 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
Check disk storage space
The Lecture Recorder x2 has a finite amount of storage: 16 GB. This storage space holds a lot of recordings, but
it can get full. It’s a good idea to monitor your current disk usage.

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. See Connect 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.
4. If available storage is low, take action to remove files as discussed in File Maintenance and File and
Recording Transfer.

Lecture Recorder x2 User Guide
7-6 Storage Disk Maintenance
Schedule disk check
A disk maintenance schedule is used to check the device 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 device.
To set the disk check schedule:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.

Perform disk check
A disk maintenance schedule is used to periodically check the device 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 device 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 captured and are not part of
any recording.
To start a manual disk check:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.

7-7 Control with RS-232 / Serial Port
The Lecture Recorder x2 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 Lecture Recorder x2 with RS-232
l RS-232 / Serial Port Command Examples
Connect and Configure the RS-232 cable
To connect your control equipment to the Lecture Recorder x2 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 Lecture Recorder x2.
Only certain adapter chipsets are supported, Epiphan recommends this adapter cable.
To connect the serial port cable:
1. Attach the null modem cable to the control interface.
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.

7-8 Control with HTTP Commands
7-8 Control with HTTP Commands
The Lecture Recorder x2 has an HTTP API interface for configuration and control by a third party application or
with a script that sends commands to the device 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 Lecture Recorder x2 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.
To Get configuration settings:
http://<address>/admin/get_params.cgi?key
To Set configuration settings:
http://<address>/admin/set_params.cgi?key=value
Where <address> is the IP address of the device, 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/get_params.cgi?product_name&firmware_version
Or, to set the stream type (streamtype) to ASF and the bitrate (vbitrate) to 256,000:
http://<address>/admin/set_params.cgi?streamtype=2&vbitrate=256K

username and password when viewing or setting configuration items.
The syntax for wget commands is shown below. Specify your device’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:
wget --http-user=admin --http-passwd=<password> http://<address>/admin/get_
params.cgi?<key>[&<key>]
set_param using wget:
wget --http-user=admin --http-passwd=<password> http://<address>/admin/set_
params.cgi?<key>=<value>[&<key>=<value>]
HTTP Command Examples
Some configuration of the VGADVI Broadcaster Pro can be done by non-interactive http commands. The
following examples demonstrate how to use wget to exercise some of the HTTP commands supported by the
device.
For values with spaces, encode space as %20. i.e.: set_params.cgi?framesize=640%20x%20480
The examples assume a system IP address of 192.30.23.45 and admin password pass123.
1. To get the broadcast stream type and frame size:
wget --http-user=admin --http-passwd=pass123 http://192.30.23.45/admin/get_

PART 8: Releases and Features
This section outlines the features introduced with each product release.
Release 3.11 Features
Improved USB Drive Support
Choose what happens when you insert a USB drive
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.
Additionally, the Web Interface now shows you the available free space on your inserted USB drive.
Record directly to a USB drive (VGADVI Recorder)
With VGADVI Recorder (only), you can now choose to record files directly to your attached USB drive rather than
recording to internal storage. A confidence-monitoring system shows you a read-only list of the recordings on the
USB drive.
Automatic file upload to a USB drive
As of 3.11.0, you can configure the device 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 device.
Wider support for USB flash drives
Previously some USB drives were not supported due to disk partitioning. Lecture Recorder x2 now supports USB drives
with non-typical data partitions. When the USB drive is attached, the first partition with a supported file system is used
for data storage.
See Upload to an External USB Drive.
Audio Features
Audio input level meter
Audio inputs that have an incoming signal and are part of a configured stream now have an audio signal level meter on
the stream information page.
The new mobile interface also displays the audio input level meter.
Auto Settings
Automatic selection frame size using signal resolution
To assist with stream setup, stream frame size is now configured by default with the input signal's resolution and will
follow the signal's changes of resolution.
If the input signal changes, streaming and recording is stopped and restarted. Deslect Use current signal resolution
as frame size if your input resolution will change often and you don't want streaming or recording to stop and restart
with each change.
Automatic video bitrate selection
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
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.
Universal Plug and Play (UPnP)
Device as a media controller
Enjoy the new live stream resume feature to ensure a digital media player automatically gets the stream when it
becomes available after the Lecture Recorder x2 restarts. Simply choose a stream and the UPnP-enabled media player to
control.
See Stream content using UPnP.
Play on digital media players from the web interface
Direct your digital media player to play a recorded MPEG-TS files from the device. Browse to the Files Archive and press
the play button to choose from accessible uPnP media players.
See Stream content using UPnP.
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://<device 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 Lecture Recorder x2 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 Lecture Recorder x2 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 Starting with release 3.11.0, you can customize the prefix used for recorded files. Use this to identify files being
auto-uploaded 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
l Customize the buttons on your Lecture Recorder x2. Select the action for the two buttons on the front of the
device, and for attached USB mouse or keyboards.
l Inputs that have an incoming signal and are part of a configured channel can be previewed on the Stream
Setup page. A static screenshot is shown and can be updated manually by clicking reload screenshot.
l Encode SVideo input without DVI or VGA input. You can now enable or disable the VGADVI input on your
Lecture Recorder x2. When disabled the S-Video input will be the only source used for the resulting stream. By
default VGADVI is enabled, and it is always the primary input if both inputs are enabled. Disable it from the
Stream Setup page.
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 Lecture Recorder x2. MPEG-TS files are ready for streaming over
HTTP, RTP and UDP.
l Ensuring multiple sources are synchronized and time-stamped precisely is easier than ever. with support for
PTP time synchronization.
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 MPEG-4 Advanced Simple Profile.
