Exactly. That's the point: RFC 3550 does allow for several streams to be multiplexed on the same port. The typical example here is two cameras sending video from different angles, thus using different SSRCs but the same media. I recommend you take a look at the AVT mail archives.

Cheers,

José

	Subject: RFC 4588...
	
	
	Hi,
	 
	I was going through the RFC and I have a doubt regrading association scheme in SSRC multiplexing. 
	 
	5.3.  Association at the Receiver
	Why the receiver MUST NOT have two outstanding requests for the same packet sequence number in two different original streams before the association is resolved.
	 
	I think it is not required as client knows that in case of SSRC multiplexing both the original and retransmission streams and no other streams would always be received on the same port with different SSRCs. So if i receive a packet with new SSRC on the same port I can easily conclude that it belongs to the retransmission stream and can associate it with original streams. 



	 
	I can understand this to be a requirement only if multiple streams are sent on the same port with different SSRC.
	 
	I will be obliged to you if you could help me in clearing this doubt.
	 
	Regards,
	Vikal.
