The Torrent CE is a powerful solution for streaming and archiving H.323
video conferences. In order to experience the benefits of the Torrent CE
certain preparations must be made to ensure media player and firewall
compatibility. The latest version of the Torrent CE supports industry
standard media players including Apple’s QuickTime, Microsoft Windows
Media Player, and Real Networks’ Real One players. Only one of these
players is required to watch a live or archived stream. This document
assumes the viewer is using Microsoft Internet Explorer as the web browser.
While other browsers are supported, Internet Explorer 5.5 or higher is
Obtaining Proper Media Players
The Apple QuickTime player is available from Apple’s web site for free. The
latest version is 5. A visit to http://www.apple.com/quicktime will tell
you whether or not you have QuickTime installed. If you do not, you will be
prompted to install an activeX plugin. To download the QuickTime 5 player
manually, go to http://www.apple.com/quicktime/download/ and
follow the instructions for downloading the free player. After the player is
installed quit the browser and follow the setup instructions in the Setting Up
Players section of this document.
The Torrent CE requires Windows Media Player version 6.4. The current
version available for download from Microsoft is 7.0. Version 6.4 is available
with most versions of Windows in two ways. It is the default embedded
player in a browser. Therefore, there are no special requirements for
downloading version 6.4. However, if the system does not have version 6.4
it can be downloaded from Microsoft at
ault.asp. To access the external player, go to Start-> Run-> type
‘mplayer2’ at the run line. The reason Windows Media Player 6.4 is
required to view Torrent CE streams is that the video codec that is used by
Torrent CE streams is H.263. Windows Media Player 6.4 supports this codec,
however, version 7 does not. See Setting Up Players for further information.
The Real One player is available from Real Networks’ web site
http://www.real.com. Look for the “Free RealOne Player” link and
proceed with the download instructions. When installing the Real One player,
be sure that you look carefully at each setting as you install it. The player,
by default, takes over many mime types on your computer unless you tell it
not to. See the Setting Up Players for more information.
Setting Up Players
The QuickTime player, by default, is set to stream using HTTP, port ID 80.
The Torrent CE requires that the video be streamed over UDP, RTSP port ID
554. There are two ways to change these settings.
From the external player go to, Edit-> Preferences-> QuickTime
Preferences… On the top pull down menu select Streaming Transport.
Check Use UDP, RTSP port ID 554. Close the window and player.
From the QuickTime browser plugin click on the down arrow at the bottom
right. Select Plugin Settings. On the top pull down menu select Streaming
Transport. Check Use UDP, RTSP port ID 554. Close the window and all
instances of the browser.
The QuickTime player is now set up to receive UDP streaming video. To
ensure UDP firewall compatibility see the Firewall Requirements section of
There are no setup requirements for Windows Media Player 6.4. The first
time a stream is watched it will download the appropriate H.263 codec for
decompression. The viewer may notice a little bit of a delay while the player
downloads the codec for the first time. This is normal.
The only currently supported player from Real Networks is their newest
player, Real One. Real One setup requires manual download of the H.263
codec. To get the codec, open the Real One external player. Select Tools-
> Preferences… Then select AutoUpdate at the bottom of the list on the
left hand side. Click on Check for Update Now. Wait while the Real player
contacts the server. A new windows titled “AutoUpdate” will open. Scroll
down towards the bottom and check the box for H.263 Video Plug-in then
click on the Install button. This will install the H.263 codec as well as the
Real Audio 2.0 plugin. After the codec is installed, quit the Real One player.
The biggest limiting factor to watching streaming content within the
enterprise is firewall implementation. In order to view streaming content
from the Torrent CE, the following ports assignments must be followed for
any client behind a firewall.
Function Port Application
Torrent CE Access* 80 TCP In/Out Web Interface
3215 TCP In/Out Realtime Status Updates
QuickTime Streaming 554 RTSP over TCP Player Controls
6970-6999 RTP over Video/Audio Transports
Windows Media** 1755 TCP In/Out Player Controls
1755 UDP In/Out
1024-5000 Video/Audio Transports
Real Streaming*** 554 RTSP over TCP Player Controls
Chat Applet 6667 TCP In/Out Chat Input and Output
* Note: on Torrent CE versions higher than 2.0.302 port 3215 will need to be
opened for TCP as well. Previous versions use a randomly generated port for
the Call Center Java app and cannot make it through a firewall unless all
ports are opened.
** You can adjust individual clients’ players to only use certain ports within
this range to save for too many open ports on the firewall. For example:
Under Tools-> Options within the Windows Media Player the client can
select the “Network” tab to limit the ports being used to ports 1050-1051.
*** Real One player lets the client define ports within a certain range under
Tools-> Preferences-> Connection-> Network Preferences. Real One
negotiates within available ports to stream.
