Portal Server v4.1 Release Notes
These Release Notes have important information about v4.1 of the VBrick ETV Portal
Server. ETV Portal Server is a video stream and source device management system accessed
through Microsoft Internet Explorer 5.5 or higher (or FireFox 1.5 on a Mac) or through a
VBrick EtherneTV-Set Top Box. More information can be found in the ETV Portal Server
and STB user documentation. The ETV Portal Server Installation CD contains a
Setup_VBrick_Media_Control_Server_Suite_4_1_0.exe which installs the necessary ETV
Portal Server components to a target ETV Portal Server machine. ETV Portal Server v4.1
requires the installation of a license file, normally supplied by e-mail or CD-ROM.
VBrick has tested ETV Portal Server on Windows 2000 Server, Windows 2003 Server Web
Edition, and Windows 2003 Server Standard Edition. These are the only supported
platforms. Note also that ETV Portal Server also will not operate correctly on a server that is
configured as a primary domain controller.
Note VBrick does not test or support ETV Portal Server on the Advanced, Enterprise, or
Datacenter versions of Windows 2003 Server.

The Windows 2003 Server Web Edition or Standard Edition installation disks are
required for the install.
A minimum of 100 MB free disk space. Substantial additional disk space will likely be
needed when ingesting or recording video.
IIS Web Server and IIS FTP Server functionality must be enabled. The installer will
determine if this needs to be installed.
Windows Service Pack 1 is recommended.
Windows 2000 Server
•
•
•
•

Security Policy and Recommendations
VBrick has fully tested the all of its server-based software products on Windows 2000 Server
and Windows Server 2003 (Web or Standard Edition with Service Pack 2) with all current
Microsoft security updates installed. It is standard VBrick policy to configure and ship our
servers with all current service packs and security updates as of the shipping date of the
product. We also run limited regression tests when new service packs are released by
Microsoft. Once VBrick software is installed at a customer site however, it becomes the
customer's sole responsibility to install security updates and software patches as they become
available. To protect against imminent threats, VBrick recommends you install and/or test all
Microsoft security updates as soon as they become available.

Linux/Macintosh Performance
The following tables show maximum throughput on Macintosh and Linux machines running
only the embedded video player—and no other applications. It is important to note that the
performance of all ETV Portal Server media/stream players depends on the power of the
client machine. In general, performance limitations are more obvious on Macintosh or Linux
clients than on Windows PCs.

Portal Server v4.1 Release Notes
Caveats
This section addresses known issues in this release, most of which have an easy workaround.
For more information about any item, or help with an issue not listed here, contact your
reseller or VBrick Support Services.
•
•
•
•
•
When recording from a WM encoder to a Network Video Recorder (NVR) 40 machine,
and using the Best Quality template, the NVR's maximum recording capacity is reduced
to approximately 10 streams. Other WM templates are not affected.
When scheduling a recording from a WM Appliance, RTSP and HTTP streams are both
displayed in the Scheduler as RTSP.
When recording a stream from the WM IPR in Portal Server mode, a rectangular red box
is displayed in the lower-right area of the window to show that a recording is in progress.
If you never leave the page, you can stop the recording by simply pressing the Record
again. If you leave the page however (e.g. if you choose MENU and select another option),
you must reselect the stream (and then press Record ) to stop the recording and close the
box.
When using dual NICs on any Windows VOD server, communication between the NICs
may fail if there is no path in the routing table from one NIC to the default gateway. To
work around this issue, add a path to the default gateway as explained in the Windows
Server documentation.
If installing the Portal Server "Software Only" VBrick product on a machine with
Windows 2003 Server Standard Edition, a "404 Page Not Found" may be displayed when
you try to launch the Portal Server. To resolve this issue, you must add the Network
Service permission to the Microsoft .NET directory as follows:
1.
2.
3.
4.
•
•
•
•
Go to C:\WINDOWS\Microsoft.NET\Framework .
Right-click on v2.0.50727 , then select Security and press the Add button.
Press the Advanced button, press Find Now, and scroll to the Network Service user.
Click on the Network Service user and press OK . Then click OK again and Apply.
If the Receive Address Mode of an MPEG-2 decoder is configured for Program Name,
and the Portal Server is scheduled to stream to this VBrick, the video will not play as
scheduled. There is no workaround. This is a known bug and will be fixed in v4.2.
QuickTime (using Firefox or Safari) does not support Fast Forward or Rewind when
playing a stored MPEG-4 stream. The FF and RW buttons on the QuickTime player
simply pause the stream.
When ingesting content to a VOD-W Server, all content titles must begin with a forward
slash (/) and apostrophes are not allowed.
There may be a conflict if VBPresenter and the Portal Server are installed on the same
machine. Both of these VBrick applications can be configured use the Web Server and
the Default Web Site in IIS. However there is only one "default" web site in IIS and only
one application can be configured to use it at a time. MCS automatically sets the Default
Web Site > Home Directory > Local path to: C:\Program Files\VBrick\MCS and the
following command will launch the MCS client interface:
http://<PortalServerIPAddress>
However, if the Default Web Site > Home Directory > Local path is being used by
VBPresenter, and is set to VBPresentations for example, the following command will
launch the VBPresenter Presentations listing page:
ETV Portal Server Release Notes
9
http://<WebServerIPAddress>
These IP addresses are identical but since there is only one IP address for the IIS Web
Server, the application that is currently configured to use the Default Web Site will launch
properly; the other will not.
•
When scheduling a live or a stored broadcast from a VBrick appliance that has multiple
bit rate (MBR) enabled, the scheduled broadcast will use the VBrick's configured bit rate
regardless of the template setting in the Scheduler. In this scenario, the Scheduler may
generate error messages similar to the following on both the Portal Server's Diagnostics
page and the VBrick's System Log. These messages can be safely ignored and the
schedule will execute properly.
Failed to Set<vbrickSlot1EncoderNetwork TransmitEnable=1>
Slot1EncoderTemplateApplySet set to applySet failed
•
Users in the Internet zone (as defined in the LAN/Internet Address Range ) cannot use the
feature if the MCS Portal Server is behind a firewall and accessed via a NATed
address. Add Video is only available to Internet users if the Portal Server's native IP
address is directly accessible from the Internet.
When creating a stored broadcast schedule, the schedule will fail to create if the schedule
Start date and End date are different (for example if it starts on one day and ends on the
next). The end date and time in the schedule are adjusted to the duration of the stored
file (except for Windows Media or Darwin files) but Create Schedule returns an error
message. To work around this issue, simply click Modify and then click Finish .
When you schedule a multicast of stored MPEG-1 content files from an NXG VOD
server, you will only see set top boxes as destination devices. MPEG-1 decoders cannot
play these streams from an NXG server and consequently are not shown as available
destination devices. Non-NXG servers, however, do not have this issue. All decoders
and set top boxes are available as destination devices for non-NXG servers.
Manually-entered URLs for live streams cannot be used for scheduled recording from
any VBricks. Manually entered URLs are not available in the live record list and will not
work if entered manually. To work around this issue in the Scheduler, use multicast IP
import (MPEG-1 and MPEG-2) or reenter the URL (MPEG4 and WM).
When playing a stored video on the external player, if you upload an image for a
thumbnail, and then switch streams while the Update Image panel is still open, any
subsequent thumbnail you upload will be applied to the first stream for which you
originally uploaded a thumbnail.
When using a Macintosh with Safari, you cannot always launch a stored stream from the
Scheduler page by clicking on the TV icon. To work around this issue, launch the stream
from the Live Broadcasts page instead.
Macintosh only. The mute button is not "sticky" and works for the selected (live or
stored) stream only . If you select a different stream, it will not be muted.
Batch recording to an NVR from a WM VBrick encoder is not supported; the Batch tab
is greyed out on the Scheduling page. Batch recording is supported from all other VBrick
encoders.
Windows 2000 only. If you use a camera that does not support closed captions, with a
VBrick encoder that has CC enabled in IWS, the video stream in the Portal Server player
will go black when you click CC ON (in both Internet Explorer and Firefox).
Windows 2000 only. In some cases when playing a stored WM clip, the video stream in
the Portal Server player will go black when you pause the stream and then press Play. To

Windows Server 2003 only. The Portal Server typically runs behind a firewall and is
installed by default with Windows Firewall set to Off. If necessary, you can use the
following steps to configure the Portal Server to run with Windows Firewall set to On .
1.
Go to Start > Settings > Control Panel > Windows Firewall . Check that the Firewall is
and Don’t allow exceptions is not checked.
To allow client access to the web server, go to Exceptions > Add Port and add Port
80 (TCP) to the Exceptions list.
To enable FTP, go to Exceptions > Add Port and add Port 21 (TCP) to the
Exceptions list.

Depending on the order in which they were originally installed, video streams may not
run in the embedded player after you uninstall Internet Explorer ActiveX controls or
Firefox plugins. To work around this issue in Internet Explorer, go to Start > Control
Panel > Internet Options > Settings > View Objects and remove the following objects (if
present) with Internet Explorer closed: CVBUI , CFtpClientMgr Object , VBrick
Streamplayer Components, VBrick MPEG4 Components. Then go to MCS and re-install
them when prompted. To work around this issue in Firefox, simply download and install
the browser from Mozilla.
When switching between streams and/or switching between the integrated player and an
external player, the embedded Windows Media Player will sometimes lose its ability to go
fullscreen. This is a documented Microsoft problem with a patch available from:
http://support.microsoft.com/?kbid=912452&SD=tech
If a Set Top Box will not play live MPEG-4 multicasts in MCS mode, verify that the
VBrick SAP Format is ISMA Compliant and that Session Information has been configured.
In IWS go to Configuration: Encoder > Announce (SAP) to configure these parameters.
With Windows 2003 Server (Web or Standard Edition with Service Pack 2 and Automatic
Updates selected), warning messages can be generated by the Data Execution Prevention
(DEP) software. To workaround these messages go to Start > Control Panel > System >
Advanced > (Performance) Settings > Data Execution Prevention and add the flagged
VBrick module as an exception.
If you are FTPing non-English file names in IIS (for example when using the Portal
Server SDK), there may be issues with Unicode support. If file names are not correctly
displayed, go to Control Panel > Regional and Language Options > Languages and select
Install Files for East Asian Languages. After rebooting go to Control Panel > Regional and
Language Options > Advanced and select a language in the Language for non-Unicode
programs control box. After a reboot the file names will display in the selected language
on the FTP site using a command prompt window (on a Windows XP machine) or the
Internet Explorer browser.
MPEG-1 encoder/decoder appliances with main board assembly numbers below 61000010-0114 and MPEG-1 decoder only appliances with main board assembly numbers
below 6100-0010-1214 do not support closed captions. If these appliances are scheduled
as decoders with Closed Captioning either Enabled or Disabled (and not to As

the stream will not play and <invalid parameter> messages may be
displayed in the Admin Console Diagnostics page.
When creating a Live Emergency Broadcast template from a WM appliance, if you set
Advanced Settings > Schedule Start Options > HTTP Push to Enabled the existing
Encoder Server settings will be used. Therefore, you also need to configure the WM
appliance for the push. In IWS, go to go to Configuration: Encoder > Server and
configure the Server Name or IP Address and Publishing/Mount Point. See "Creating
Publishing Points" in the WM Appliance Admin Guide for more information.
If you configure an MPEG-4 appliance with Audio and Video disabled and Closed
Captions enabled (in extremely low bandwidth applications, for example), you must have
CC ON set in the embedded Portal Server player or no stream (from any appliance) will
play. If this happens, set closed captions to On , then close the browser and restart.
When configuring the Portal Server to use LDAP database for access control, be aware
that an LDAP user for Auto Ingest via XML is not supported. You must create and select
a VBrick user in Global Assignments or the Event Viewer will display: Failed to update
ingestion status: Input string was not in correct format.

Closed captions are not displayed when playing WMV streams on a Macintosh.
When configuring a Content Expiration Warning Recipient under Global Assignments,
the e-mail address for the recipient must be in the local domain.
On Portal Server v3.2 or higher, an autoingest folder is not created until you record a
program for the first time. If you want to autoingest before a recording, you must
manually create the autoingest folder at d:\inetput\ftproot\mcs\autoingest . If you don't
have a d: drive, use c:\inetpub\ftproot\mcs\autoingest .
The VOD W server supports streaming of MPEG-4 closed captions; the NXG server
does not. This means that if you have access to two servers (a VOD W and an NXG),
and you perform a pushbutton recording of an MPEG-4 stream with closed captions, the
closed captions track is stripped from the recording.
Depending on user requirements, VOD users can be restricted to viewing RTSP streams
at a specified bandwidth in Kbps. This feature is not currently supported for Darwin and
VOD-WM video-on-demand servers.
In some cases, because of a naming resolution issue, a LAN Network Video Recorder
(NVR) does not record when the ETV Portal Server server is in a DMZ. As shown on
the status page, the recording will either fail or run indefinitely (without actually
recording). To work around this issue, modify (or create) a hosts file on the ETV Portal
Server as shown below. Go to c:\windows\system32\drivers\etc\hosts. Open the
hosts file in an editor and add the IP address and computer name of the NVR as shown
below. (If the hosts file is not present, you must create one by saving a txt file with no
extension.)

This is a sample HOSTS file addresses to host names. Each
entry should be kept on an individual line. The IP address should
be placed in the first column followed by the corresponding host name.
The IP address and the host name should be separated by at least one
space. Additionally, comments (such as these) may be inserted on
individual lines or following the machine name denoted by a '#' symbol.
For example:

Portal Server v4.1 Release Notes

The duration of Darwin and WM video assets is not extracted in this release. As a result,
the duration of a stored broadcast schedule for a Darwin or WM asset will not be
automatically adjusted to the actual length of the clip. This means that the video asset
plays until file end but the multicast continues until the end of the scheduled time.
Multicast streaming from the VOD-D (Darwin) server is not supported.
Not all Windows Media servers support multicast streaming. Only Windows Media
Services 9 Series running on Windows Server 2003 Enterprise or Datacenter Edition
support multicast.
To access a Windows Media Server from an ETV Portal Server running on Windows
2000 Server, you must make a change in the configuration file. Go to
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\CONFIG\machine.config. In the
<system.web> tag in the <processModel> section, change userName="machine" to
userName="SYSTEM"

The VOD-D (Darwin) server does not support playback of H.264 content. If you try to
play H.264 content, the audio track will play but the video will be blank.
To avoid problems when recording content, the Windows Firewall must be set to Off. Go
to Start > All Programs > Windows Firewall to turn it off.
Use care when configuring virus scanning software. To avoid problems when recording
on the ETV Portal Server, do not scan any folders into which recorded files are being
saved. This is typically: D:\Inetpub\ftproot\MCS\Record.
When creating an Emergency Broadcast template for a live broadcast and manually
selecting MPEG-4 and Program Name, the destinations available page shows only
VBricks—it does not show STBs. Manual entry of Program Name does not apply to
STBs.
If an ingestion fails after a record and you wish to use the auto-ingest feature, be sure to
purge the failed ingestion on the Status page before attempting the auto-ingestion.
The ETV Portal Server and the Network Video Recorder (NVR) must be in the same
time zone. Also, in order to record successfully, the system time on ETV Portal server
and the NVR must be synchronized. You can synchronize the machines, for example, by
running the Service for Windows Time on both machines.
When scheduling a broadcast of MPEG-4 content from an InfoValue server to a VBrick
decoder, v3.3 software must be installed on the VBrick or the video will not play. Also
the MPEG-4 file must be "hinted" or it will not play properly on the VBrick decoder.
Hinted files contain reorganized data that facilitates streaming, fast forward, rewind, etc.
The online help pages are best viewed with Internet Explorer 6.0 (or Firefox 1.5 if using
a Mac) at a minimum screen resolution of 1024x768 using Normal size (96 DPI) fonts.
The pages may not display or function properly with earlier versions or other browsers,
for example MAC OS X with Safari.
When IIS installs the FTP service, a default FTP directory is created at
drive:\Inetpub\ftproot. In MSC 4.1 the Record Path must be in the FTP path of the
Record server, for example: C:\Inetpub\ftproot\MCS\Record. To set Record Path in ETV
Portal Server, go to Global Settings > Recorders > Modify Recorders > Record Path .
You cannot create or upload thumbnails for Live Video streams that were added using
the ETV Portal Server Global Settings > URLs functionality. Any attempt to create
thumbnails for these URLs will fail.
VOD Polling interval requires a restart before changes take effect. On Admin page, go to
Global Settings > Global Assignments > Assign VOD Polling Interval . If you change the

value, you must restart Vbrick Object Starter Service on the ETV Portal Server for this
parameter to take effect.
When using the Scheduler, be aware that all VBrick encoder/decoder resources must be
available at the date and time of the scheduled event. When creating a schedule, ETV
Portal Server verifies that the resources are currently present on the network but there is
no way to determine if these resources will still be available at runtime. If there is a
subsequent resource conflict, for example if a VBrick is disabled and not available (or the
hard drive on a VBStar is full), the encoder/decoders will not connect for the scheduled
event and there will be no video between the devices. Similar problems will occur if the
ETV Portal Server and VOD server clocks are not synchronized. See the VOD
documentation for more information.
With an NXG server, you can manually ingest video files to the server as documented.
However you cannot use the Add Video command from the client application to add these
same files. This feature is not available with Omnibase servers. Contact VBrick Support
Services for more information.
There is an issue with Admin settings for Allow Access to Specific VOD Content and
Allow Content Publishing. If you check a parent directory, the sub-directories are also
checked to indicate that the user has access to all sub-directories. However, at present
there is no way to keep the user from unchecking a subdirectory. Regardless whether the
user unchecks a sub-directory whose parent directory is checked, ETV Portal Server will
still allow access to the sub-directory.
There is an issue ingesting MPEG-4 content when closed captioning is enabled.
Depending on the version of NXG software on the server, the ingestion may either fail
or not playback. VBrick provides a utility to remove the closed captions track from an
MPEG4 file if necessary. It is installed with ETV Portal Server in c:\program
files\vbrick\utils. See the ETV Portal Server Admin Guide for details.
The installer now changes the default root password for the MySQL database from no
password to vbrick_18.
For Macintosh when using IE, clicking on the scrollbar might cause a stream/video to
play. Use the arrows to avoid this when viewing the playlist.
For one-click login, if you type in the IP Address, rather than the name of the machine,
you will be prompted for a username/password box. This is intended behavior as IE sees
the IP Address and believes the user is in the Internet Zone. If you click on Remember
my password you will not see the box again.
The default FTP path in IIS is automatically set via the installer, but, depending on the
particular machine’s configuration, it may need to be changed. The installer sets the
default FTP path to d:\inetpub\ftproot in IIS, if a D: drive is detected. Otherwise it sets
the path to c:\inetpub\ftproot. If you have a machine with an E: drive and you want to
set the FTP path to E:, you need to do the following: Go to IIS and use the right mouse
button to select on the Default FTP Site, select Properties from the popup menu. The
Default FTP Site Properties dialog box will appear. Select the Home Directory tab. In the
Local Path edit box, change the value to e:\inetpub\ftproot and hit OK .
If a user has defined a default STB channel, and then removes that particular customized
channel in the Customize Streams page, that default STB channel is still listed as the
current channel, even though it no longer exists.
