StreamPlayer License Server
Note Microsoft Windows Media is a trademarked name that identifies operating system
features and technologies that are designed to create, edit, play, and distribute
streaming media. The VBrick WM Appliance is a VBrick device that encodes Windows
Media-formatted content so it can be distributed over a network.
StreamPlayer Overview
Any references to StreamPlayer in this document apply to both StreamPlayer for Windows
Media and StreamPlayer with MPEG-2 Playback. The only difference is the type of video that
each supports. See Supported Versions for a complete list of options. The desktop versions
of StreamPlayer and StreamPlayer Plus both support the following features:
•
•
•
Viewing live streams
Playback of files
Display of closed captions
These features are supported for MPEG-1 and StreamPlayer WM (Windows Media).
MPEG-4/H264 support is added with StreamPlayer. MPEG-2 support is provided in
StreamPlayer with MPEG-2 Playback and the StreamPlayer Plus versions. StreamPlayer may
also support MPEG-2 video if an MPEG-2 decoder is installed on the PC. For example, if
StreamPlayer Admin Guide

the computer has a DVD player, then there is an MPEG-2 decoder installed. StreamPlayer
will be able to use this decoder in most cases. StreamPlayer Plus adds the following features:
•
•
•
Recording of MPEG-1, MPEG-2, MPEG-4, and WM streams. Recording can be
password protected.
Editing of MPEG-1 and MPEG-2 files.
Capture driver functionality.
Note StreamPlayer and StreamPlayer with MPEG-2 Playback can also be deployed as an
automatic download from a web server. See Web Deployment Toolkit on page 9 for a
discussion of how to deploy StreamPlayer in this manner.
StreamPlayer and Windows Media
StreamPlayer Plus launches Windows Media Player to play MPEG or WM streams on the PC.
StreamPlayer will use the latest version of the Windows Media Player that is installed on the
machine.

StreamPlayer Components
StreamPlayer
The various forms of StreamPlayer allow MPEG-1, MPEG-4/H.264, and Windows Mediabased content video to be played on PCs. StreamPlayer with MPEG-2 Playback additionally
allows MPEG-2 video to be played on PCs. Both can be deployed either via a desktop install
(.exe) or via embedding the components in a web page. The components, including sample
HTML pages, required to embed the video in a web page are called the StreamPlayer Web
Deployment Toolkit. When deployed in this method, the StreamPlayer components are
automatically downloaded to the desktop from the web page.
Note A separate version of StreamPlayer is available without support for MPEG-4/H.264;
this version is freely distributable without limitation. A version with MPEG-4 support
is available for free for up to 1,000 users. There is a nominal charge for additional
users.
StreamPlayer Plus
StreamPlayer Plus is a full-featured version that is deployed via a desktop install (.exe). It
includes the same features as StreamPlayer and StreamPlayer with MPEG-2 Playback, and
also provides:
• The ability to record MPEG-1, MPEG-2, MPEG-4/H.264, and WM streams.
• The ability to edit MPEG-1 and MPEG-2 files.
• Capture Driver software, which allows MPEG-1 and MPEG-2 video to be decoded and
then transcoded into different formats (JPGs, Windows Media, Real, etc.) via third party
software.
• Built-in FTP enables instant transfer of recorded files to a remote server.
• Category filtering protection on a per stream basis restricts streams to authorized
viewers.
StreamPlayer License Server Software
StreamPlayer License Server Software, based on the industry standard FLEXlm, is an
optional component when more than 100 StreamPlayer with MPEG-2 Playback or
StreamPlayer Plus licenses are purchased. License Server software offers concurrent MPEG2 license management, allowing the number of purchased licenses to be based on the number
of simultaneous viewers rather than the total number of PCs on which it is installed.
StreamPlayer with MPEG-2 Playback and StreamPlayer Plus contact the license server to
obtain an MPEG-2 license in order to view MPEG-2 video. When the video stops, the license
is returned to the server. The software can be installed on any Windows-based server in the
network, including the EtherneTV Portal Server or the web server hosting the StreamPlayer
components, if applicable.
Note The StreamPlayer License Server is repeatedly accessed by computers throughout the
network and requires a reliable network connection.

Sigma Decoder Card
Both StreamPlayer and StreamPlayer Plus work with the Sigma NetStream 2000 hardware
decoder card. The Sigma card can be installed at any time and will be recognized by the
StreamPlayer or StreamPlayer Plus software. The benefits of using a hardware decoder card
include reduced CPU utilization and reduced latency. The drawback is that hardware cards
require installation in each computer. The NetStream 2000 decoder card supports MPEG-1
and MPEG-2.
StreamPlayer Implementations
Methods to Receive Video
StreamPlayer is an extremely flexible software player and allows customers to receive video in
a variety of ways. Some of these include:
MPEG-1/2/4/H.264 and Windows Media Multicast
Dedicated MPEG-1/2 Unicast
RTSP MPEG-4 Unicast
RTSP MPEG-4/H.264 Interleaved/HTTP-Tunneled Unicast Streams
Windows Media HTTP Unicast Stream
Windows Media RTSP Unicast Stream
MPEG-1/2/4/H.264 and Windows Media Multicast
The most efficient way of transmitting live video is via multicast. In a multicast video
transmission, the video stream is sent to a multicast IP Address. The VBrick appliance
transmits to the multicast address and StreamPlayer software can be set to listen to the
address to play the video and audio streams. The StreamPlayer and StreamPlayer Plus
desktop players make it extremely easy to view live multicast video because it will
automatically list the available multicast streams in the Program Info window. The end user
simply needs to click on one of the Program names and the video will begin playing. Similarly,
using the StreamPlayer Web Deployment Toolkit, web masters can create links with the URLs
to the multicast IP addresses. When users click on the link, the video will begin playing.

Getting Started
Note Multicasting is not generally available on the Internet. If the LAN supports multicast,
administrators can take advantage of all the features of this method of delivering video
streams. The diagram above shows an MPEG-4 multicast but the diagram is also
applicable for MPEG-1, MPEG-2, and WM multicasts.
Dedicated MPEG-1/2 Unicast
For environments that do not support multicast, or for environments where a private
communication is desired, a Dedicated Unicast can be sent from a VBrick to StreamPlayer.
For Dedicated Unicast, the VBrick is set to transmit audio and video to a single Unicast IP
Address. The Unicast address configured in the VBrick should be the destination IP Address
of the computer on which StreamPlayer software is running. The StreamPlayer user would
enter the IP address of the VBrick in the IP address field of StreamPlayer. The diagram
below depicts an MPEG-4 unicast, but the diagram is applicable for MPEG-1 and MPEG-2
unicasts also.
RTSP MPEG-4 Unicast
For On-Demand video and for Live video coming from a VBrick MPEG-4 encoder
(VBXcast), it is also possible to initiate a unicast stream by connecting via RTSP (Real Time
Streaming Protocol). Using RTSP to view video is similar to using a web browser to view a
web page. For example, where the "location name" of a web page begins with http://, the
"location name" of an MPEG-4 video stream begins with rtsp://, for example rtsp://
ipaddress/vbrickvideo1. The URL can be entered into the IP address field of StreamPlayer
or StreamPlayer Plus. Alternatively, the IP URL can be linked to in a web page. Clicking on a
link will launch the video in StreamPlayer.
StreamPlayer Admin Guide

RTSP MPEG-4/H.264 Interleaved/HTTP-Tunneled Unicast Streams
For environments where UDP traffic is not allowed, the MPEG-4 stream can be sent over
TCP (interleaved) or HTTP (tunneled) channels. This is ideally suited for Internet
environments where the players and the encoders could be behind firewalls. The streams are
unicasted to the player. Interleaved play back consumes less bandwidth compared to tunneled
playback. However tunneled playback is more suitable because most firewalls allow HTTP
traffic to go through, especially over port 80. See the topic "MPEG-4" Preferences in the
StreamPlayer User Guide for more information on how to configure the player to receive these
unicast streams. See also Source Filter Tags on page 14 for more about receiving these
streams via the embedded Windows Media Player.
Windows Media HTTP Unicast Stream
The VBrick WM Appliance supports HTTP streaming. The player can choose to receive such
a stream when it is behind a firewall or when the network does not support multicast traffic.
The stream is unicasted over a regular HTTP channel. You can type in the HTTP URL to the
stream in the IP address edit box of StreamPlayer. For example:
http://172.22.167.40/vbrickvideo1
Windows Media RTSP Unicast Stream
Another way to receive a unicast VBrick Windows Media stream is over UDP. This consumes
less bandwidth compared to a HTTP stream but the stream may be blocked by some
firewalls. This type of stream is suited for environments where firewalls are not an issue but
the network does not support multicast traffic. You can type in the RTSPU URL to the
stream in the IP address edit box of StreamPlayer. For example:
rtspu://172.22.167.40/vbrickvideo1
Installing StreamPlayer
Standard Desktop Installation
Run SetupStreamPlayer_5_x_x.exe. All StreamPlayer software installs by double-clicking the
application .exe file and following the directions on the screen. If InstallShield encounters a
previous copy of StreamPlayer or StreamPlayer Plus, a notification appears. Press Ok to
continue. A license file and a serial number are required during installation.

Serial Number – the nine-digit serial number for your software is attached to a sticker on
the StreamPlayer Product CD.
License File – a license file is required for installation of StreamPlayer with MPEG-2
Playback and StreamPlayer Plus.
Enter your serial number and navigate to the license file when prompted (license files end
with an .lic extension). Browse to the location of the license file and then select Open or
simply double-click on the file name. VBrick recommends that the default folder and settings
be used. Select Finish to complete installation. The setup file for Windows Media and
MPEG-1 playback (Setup_WM_StreamPlayer_5_x_x.exe) only installs Windows Media and
MPEG-1 components. This free StreamPlayer application that has limited functionality and
does not prompt for a license file.
Note Windows 7 only. The Windows Media Player will not play video launched from
StreamPlayer with the default settings. To enable video from StreamPlayer on
Windows 7, go to Start > Control Panel > Windows Firewall > Advanced Settings >
Inbound Rules. Right-click on Windows Media Player (UDP-In) , select Properties, and
enable UDP-In on the General tab.
Silent Mode Installation
Deploying StreamPlayer or StreamPlayer Plus to thousands of desktops is best done through
deployment tools such as Microsoft’s Systems Management Server (SMS). Tools such as SMS
make it easy for administrators to push software installations across the network to PCs with
no interaction from the end-user. Because the installations run in the admin mode there is no
user permissions issue. A major requirement for setup programs run by deployment tools is
the ability for them to run in silent mode. The setup programs should not wait for user input
as they are most often run when there is no user logged on to the machine. See Running a
Silent Setup below.
Extracting the Package
StreamPlayer Setup is a self extracting executable. If you were supplied with the package
SetupStreamPlayer_5_x_x.exe, please follow the steps below to extract the Setup.exe and
other files from this package. Run the following command at your command-line prompt.
After you hit Enter, please cancel out of any InstallShield window that may open. Do not
proceed with the installation. This step is only needed to extract the Setup.exe package from
the SetupStreamPlayer_5_x_x.exe.
SetupStreamPlayer_5_x_x.exe –f<absolute-path-to-a-folder>
The folder specified in the above command will contain all the extracted files including the
file Setup.exe.
Running a Silent Setup
Use the following generic command to run a silent install. Note that you will need to replace
the generic serial number placeholder in the sp-install.iss response file (see Table 1 below)
with the actual serial number from the sticker on the StreamPlayer Product CD. Be sure to
modify this file before you run the installer.
Setup.exe <absolute path to license file> -s –f1<absolute path of install
response_file>
For example, open a Command Prompt and enter the following:
StreamPlayer Admin Guide
7
Setup.exe c:\myFolder\mylicense.lic –s –f1c:\myFolder\sp-install.iss
Table 1. Command Line Parameters.
setup.exe
This is the setup file for the StreamPlayer application.
Absolute path to
license file
The first command line parameter should be the absolute path to the
license file that you received from VBrick. The license file ends with
an .lic extension. While installing Windows Media only StreamPlayer
this parameter is not required. While installing the free StreamPlayer
that supports MPEG-4 this parameter should be pointing to default-42.lic.
-s
This switch tells the Setup to run in the silent mode, i.e. no dialog
boxes thrown, no status displayed.
-f1<absolute path
to install response
file>
A response file contains the inputs required for the silent setup to run.
Usually the user gives these inputs but because there is no user
interactions in the silent install a response file is used instead. Use the
VBrick-supplied install response file (sp-install.iss). The response
file can be found on the Product CD in the following location:
software\response-files-for-silent-install
Note If you want to install StreamPlayer to a location other than the default location
(c:\program files\VBrick\StreamPlayerPlus) you have to modify a single line in the
.iss file. Please open the sp-install.iss file in any text editor (Notepad, Wordpad, or
equivalent). Look for the line “szDir=C:\Program Files\VBrick\StreamPlayerPlus”.
Change it to “szDir=newPath”, where ‘newPath’ is the location you want the
StreamPlayer installed.
Upgrading
Upgrading of older versions is done automatically. The commands for a silent upgrade are
same as the commands for a silent new installation.
Uninstall
Use the following generic command to run a silent uninstall:
Setup.exe -s –f1<absolute path of un-install response file>
For example, open a Command Prompt and enter the following:
Setup.exe –s –f1c:\MyFolder\sp-un-install.iss
As you can see the parameters are similar to that of an install except for two important
differences: (1)the uninstall does not require a license file; and (2) the response file to use is
sp-un-install.iss

Overview
StreamPlayer can be deployed either via a desktop install (.exe) or via embedding the
components in a web page. The components, including sample HTML pages, required to
embed the video in a web page are called the StreamPlayer Web Deployment Toolkit. When
deployed in this method, the StreamPlayer components are automatically downloaded to the
desktop from the web page. This chapter focuses on the deployment of StreamPlayer by
downloading the StreamPlayer components from a web server. VBrick makes this easy to do
by providing the following functionality to users:
•
•
•
Cabinet files (.cab) files – These files contain the necessary software which needs to be
downloaded to the PC to allow MPEG stream viewing. The .cab files only work with
Internet Explorer browsers (6.0 or higher recommended) on PC platforms. When the
user accesses a web page with a .cab file embedded on it, they will get a popup window
that asks them if they want to install the software. When they click Yes, the software is
automatically downloaded onto their PC.
Web Page Templates – These templates provide all the information needed to develop
the web pages to download the .cab files and also to link to a particular video. Several
different templates are provided which differ in the type of stream (MPEG-1, MPEG-2,
and MPEG-4) and the access mechanism (multicast vs. RTSP).
HTML Generator Utility – This software allows users to input various parameters,
including type of stream (MPEG-1, MPEG-2, or MPEG-4) and the address of the stream
and have a fully activated HTML page created automatically.
Note You can also use standard Microsoft web tools to embed streams from VBrick
appliances in your web pages.
Installing the Toolkit
In order to access the functionality of the toolkit, the components need to be installed by
running the SetupStreamPlayerWebDeploymentKit_4_x_x.exe from the VBrick Product CD.
VBrick recommends installing the application in the default location. If the default location is
used, the components will be located in C:\Program Files\VBrick\StreamPlayer including:

Using the Toolkit
Setting up a Web Server
StreamPlayer software can be installed on a pre-existing web server, or on a new computer
configured as a web server. If Windows 2000 or Windows 2003 is the operating system,
Internet Information Services (IIS), or other web server software can be installed as web
server software. To verify that IIS is set up, go to Start, Settings, Control Panel, Add or
Remove Programs and choose Add/Remove Windows Components from the side panel. If
the box for IIS is not checked, indicating it is not configured; it will be necessary to set it up
from System Disks. Please refer to system documentation for more information on how to
install and configure web server software.
Understanding CAB Files
A .cab, or cabinet file, is a single file that holds other compressed files. During installation of
the program, the compressed files are automatically decompressed and copied to a directory.
A cabinet file usually contains .cab as the file extension. Different .cab files are installed,
depending on the application:
STREAMPLAYER1.cab
Contains MPEG-1 and MPEG-2 source filters. If viewing MPEG-1
or MPEG-2 video, the STREAMPLAYER1.cab needs to be used.
STREAMPLAYER2.cab
Contains MPEG-2 decoders for Windows XP machines. If viewing
MPEG-2 video on Windows XP machines, the StreamPlayer2.cab
needs to be used.
OLDSTREAMPLAYER2.cab
Contains MPEG-2 decoders for Windows 98 and 2000 machines. If
viewing MPEG-2 video on Windows 98 or 2000 machines, the OLDSTREAMPLAYER2.cab needs to be used.
STREAMPLAYER4.cab
Includes both the MPEG-4 source filter and decoder. If viewing
MPEG-4 video, the STREAMPLAYER4.cab needs to be used.
VBPLAYER.cab
Is the player control that can be used in conjunction with the
StreamPlayer components. The player control provides Play, Pause,
Stop, Fast Forward, Rewind, Seek, Audio Control, and Full Screen
capabilities.
HTML Templates
The StreamPlayer Web Deployment toolkit comes with five separate HTML templates which
make it easy to embed video into a web page. These templates provide all the information
needed to develop the web pages to download the .cab files and also to link to a particular
video. Several different templates are provided which differ in the type of stream (MPEG-1,
MPEG-2, and MPEG-4) and the access mechanism (multicast vs. RTSP).These templates are
as follows:

End User Operation
Once the template has been modified, the files should be placed on the web server, in the
appropriate directory. Accessing these files for the first time requires that the appropriate
.cab file be downloaded to the PC. Answering Yes to the Security Warning allows whichever
.cab file is necessary, MPEG-1, MPEG-2 and/or MPEG-4 to be downloaded. After the .cab
files are installed, the user can view video on the desktop through the customizable HTML
template pages. After the initial download, the software recognizes that the components are
installed; they are not re-installed with each use.

Using the Embedded VBrick Player Control
VBrick StreamPlayer embedded components includes a new player control that can be used
in web pages. The VBrick player control is slightly different from Windows Media Player, and
it provides fast-forward and rewind functions when used with a video server that supports
these functions, such as Kasenna and InfoValue servers. Embed the player the same way you
would any ActiveX control:
<OBJECT codeBase="VBPlayer.cab#Version=4,4,1,0" height="0" width="0"
classid="clsid:5459BAF4-09A9-422A-AB5C-5F114A7287B5" VIEWASTEXT>
</OBJECT>
Note that in this example, the player component is loaded via a code base statement and that
the object “VBPlayer.cab” is located in the same directory as the web page. Note also, if you
decide to use the VBrick player control, you should replace the sections in the sample
Windows Media Player that call the Windows Media Player. For example:
<object classid="clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6" id="wmplayer">
<param name="URL" value = "vbrtsp://VBrick_IP_address_here/

StreamPlayer Categories
Overview
VBrick MPEG appliances and Video on Demand announce their content by sending several
items in a single Service Announcement Protocol (SAP) message. Included in this SAP is a
"Category." The Category may contain nothing at all, a word, or several words. There is no
restriction to the category except that all words are case sensitive. If the same Category is
entered on both StreamPlayer and a VBrick appliance, both behave the same. The
implementation is equivalent, even though VBrick and the StreamPlayer categories operate
differently. StreamPlayer reads the Category field and displays the Program Guide for a
particular stream if there is no entry in the SAP category field or if the category is present
and it matches StreamPlayer ’s category list. The following table clarifies the matrix:
Incoming Stream
CATX
CATY
Blank
"CATX"
Displayed
Blocked
Blocked
"CATY"
Blocked
Displayed
Blocked

StreamPlayer also controls the recording of a stream based on category. The following table
illustrates StreamPlayer actions upon receipt of a stream from a VBrick appliance or VBVOD
Server containing the Transmit Category shown:
Transmitted Category
StreamPlayer Plus Action
(none)
Program is displayed in Program Guide and recording is
allowed.
norecord
Recording disallowed.
norecord=password
Recording allowed with password entry.
abcdef
Program shown in Program Guide only if abcdef is in
StreamPlayer Plus category list.
norecord abcdef
Program shown in Program Guide only if abcdef is in
StreamPlayer Plus category list. Recording not allowed.
norecord=password abcdef Program is shown in Program Guide only if abcdef is in
StreamPlayer Plus category list. Recording allowed with
password.
abcdef vwxyz
StreamPlayer Admin Guide
Program shown in Program Guide only if abcdef or vwxyz is
in StreamPlayer Plus category list.

Category Specifications
Characters are ASCII and only lowercase. The total characters contained in all the keywords
in the string is 36 characters including spaces. Categories can act as passwords. Category
entries may be simple English such as “marketing”, “sales”, and “finance”, but if someone
knows that “marketing” is a category, they might figure out that “sales” is another category.
If random words, such as “gold”, “music”, and “bird” are used, it is more difficult to guess
the right category to view private streams. The SAP Category entry can contain one or more
keywords to limit the video streams displayed. Keywords should be separated by spaces.
