URLs
Add/Modify a URL for a Live Video Stream
Administrators can manually enter URLs to live video streams that will not automatically be 
displayed by the Portal Server. For example, the administrator may wish to have the 
Announcements (SAPs) disabled on the VBrick encoders for security purposes. Or the 
Administrator may want to enter the address of an off-network stream such as an MPEG-4 
Stream from an Apple Darwin Server or a stream coming from a hosting provider. 
Additionally, this feature leys you enter the addresses of non-MPEG streams such as 
Windows Media and Real streams. Note that the Access Control feature Allow Viewing by 
Content Type doe
s not apply to manually added URLs.
The following examples show valid URL syntax for live video streams. The syntax must be 
accurate and there is no internal validation of user input:

Note
For any non-MPEG video, the correct player (such as Windows Media Player or 
Real Player) must be present on the desktop for the client to be able to receive the 
stream. Set Top Boxes will not be able to receive non-MPEG streams because the 
Set Top Box only includes decoders for MPEG-1, MPEG-2, and MPEG-4.
