2.2.8 RTCP Sender Report (SR)

  • Article

The syntax of the RTCP sender report is as specified in [RFC3550] section 6.4.1, with the following additional notes:

Sender's packet count, sender's octet count: The packet and octet counts SHOULD NOT include packet duplicates intentionally sent. For example, packet duplicates can be the retransmission of DTMF end packets, as specified in [RFC4733] section 2.5.1.4.

When there is more than one stream in the RTP session, this protocol only sends SR packets for the lowest SSRC in the SSRC range. The packet and octet counts SHOULD be the sum of packet and octet counts of all streams in the RTP session.
