2.2.12 RTCP Feedback Message

  • 아티클

The syntax of the RTCP feedback message defined in this protocol follows the syntax specified in [RFC4585]<35>.  The RTCP feedback message is configured by the method specified in [MS-SDPEXT] section 3.1.5.30.

Details of the RTCP feedback message common fields, including PT, FMT, and so on, are specified in [RFC4585] section 6.

This protocol defines one payload-specific feedback message:

§ Picture Loss Indication (PLI)

This protocol defines two application layer feedback messages:

§ Video Source Request (VSR)

§ Dominant Speaker History Notification (DSH)

This protocol MUST send out RTCP feedback messages as reduced-size RTCP messages, in the format specified in [RFC5506] section 4.1. This protocol extends [RFC3550] in the timer behavior, as specified in sections 3.2.2 and 3.2.6.
