WG,

This update is to address comments raised by Spencer Dawkins in IESG 
review. The changes are:

- Change of usage of "media stream" to mostly RTP stream.

- change wording around co-located to avoid confusion.

Cheers

> Abstract:
>     RTP allows multiple RTP streams to be sent in a single session, but
>     requires each Synchronisation Source (SSRC) to send RTCP reception
>     quality reports for every other SSRC visible in the session.  This
>     causes the number of RTCP reception reports to grow with the number
>     of SSRCs, rather than the number of endpoints.  In many cases most of
>     these RTCP reception reports are unnecessary, since all SSRCs of an
>     endpoint are normally co-located and see the same reception quality.
>     This memo defines a Reporting Group extension to RTCP to reduce the
>     reporting overhead in such scenarios.
