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. Working Group Summary The MMUSIC Working Group has consensus to publish this document as a Proposed Standard. Document Quality The document has received several reviews in both the MMUSIC WG (Colin Perkins, Roni Even, and Thomas Schierl) and the FEC Frame WG (Ulaş C. Kozat). Personnel The Document Shepherd is Jean-Francois Mule, and the Responsible Area Director is Robert Sparks.
