  1. SDP Media Capabilities Negotiationdraft-ietf-mmusic-sdp-media-capabilities-13R. Gilman, R. Even, F. Andreasen IETF 83, Paris March 26, 2012 Flemming Andreasen (fandreas@cisco.com)

  2. Changes in -13 • Got rid of “dummy” (“*”) pcfg payload-type-number in Potential Configurations (pcfg) • Was originally provided to accommodate media formats that ignore the actual media format values provided in the “m=“ line (such as BFCP) • With the -12 split of media capabilities into “RTP” and “non-RTP”, the dummy value is no longer needed. • (Non-RTP does not have payload type mappings)

  3. Changes in -13 • Significantly expanded on Offer/Answer Procedures • Would appreciate review • Updated Security Considerations

  4. “SDP Media Bundle” Interactions ? • Jonathan Lennox asked about interactions with SDP media bundles at IETF 82 • Currently draft-ietf-mmusic-sdp-bundle-negotiation-00.txt • Media Capabilities mechanism works, but inter-media description synchronization of negotiated configuration may be needed • This is however a more general SDP media bundle issue (transports, attributes, capability negotiation in general, etc.)

  5. Next Steps • All known open issues have been addressed at this point • Essentially ready for WGLC, however would appreciate volunteer review of Offer/Answer section first
