Technical Summary
This document defines semantics for grouping the
associated source and Forward Error Correction (FEC)
repair flows in the Session Description Protocol (SDP).
It obsoletes the previous RFC 4756 that defines FEC
grouping semantics in SDP by adding the three main capabilities:
a) It is now possible to indicate more than one source and/or
repair flows in the same SDP group, and
b) Additive repair flows can be sufficiently described, and,
c) SSRC-level grouping of FEC flows is now possible for
SSRC-multiplexed RTP streams.
