Compound Reports

Compound Reports

If and only if (IFF) the compound packet is to be encrypted: it is prefixed by a random 32-bit quantity selected for each compound packet transmitted.

The first RTCP packet in the compound packet must always be a report packet (either Receiver Report or Sender Report). Followed by up to 30 more report packets (as Report Count is only 5 bits).

This is followed by an Source Description (SDES) packet containing a CNAME item (other information such as NAME, EMAIL, PHONE, LOC {geographic location},TOOL, NOTE, and PRIV {private extension to SDES} are optional).

BYE should be the last packet sent with a given SSRC/CSRC.
