[AG-TECH] viewing H.261 VIC/RAT streams using QuickTime

[Laurence Kirchmeier <laurie@xxxxxxxxx>]

Merit is offering a VIC/RAT multicast stream of the NANOG 37  
conference which is currently being held in San Jose,CA. NANOG is the  
North American Network Operators Group and hold meetings around the  
US 3 times a year.
I am wondering whether anyone has put together an SDP file for VIC/ 
RAT streams that QuickTime Player could use to display the stream.    
We are using Internet2's VIC/RAT server to encode and broadcast the  
stream for us - I don't know details of that server and whether it  
can could create an SDP file describing the streams.
Any pointers or ideas of how to accomplish this would be much  
appreciated.
Cheers

Laurie
