Hi, folks:
We have submitted one new draft to discuss how to indicate which media
 source(s) in one group of media sources originating from a single endpoint 
is responsible for sending reception report. 
http://tools.ietf.org/html/draft-wu-avtcore-multisrc-endpoint-adver-02

The basic idea is to 
o Define one new SDES item and use SSRC/CSRC identifier included at the beginning of the chunk
to indicate the active report souce, 
o If alternative report source is needed, a list of Candidate report source SSRCs can be carried in the payload of this SDES item.
o Which group of media sources originate from a single endpoints can be indicated 
by requiring this item sent together with CNAME SDES item.

Regards!
-Qin

> Abstract:
>   When two endpoints with multiple media sources are in communication,
