Ballot Text

Technical Summary

In this specification, we define a framework for specifying restrictions on RTP streams in the Session Description Protocol. This framework defines a new "rid" SDP attribute to unambiguously identify the RTP Streams within a RTP Session and restrict the streams' payload format parameters in a codec-agnostic way beyond what is provided with the regular Payload Types.

This specification updates RFC4855 to give additional guidance on choice of Format Parameter (fmtp) names, and on their relation to the restrictions defined by this document.

Working Group Summary

No issues to note. 

Document Quality

There are currently no known implementations of the protocol, however the document is a normative dependency for the W3C WebRTC specification.

Flemming Andreasen is the Document Shepherd
