ABSTRACT:
Embedded within at least some Real-Time Control Protocol (RTCP) messages sent from a media content source to a recipient is a session description message that describes a media presentation being streamed to the recipient. The session description message can be associated, for example, with one of a plurality of pieces of media content in a play list of media content being streamed from the device to the recipient. In accordance with certain aspects, an RTCP message that embeds a session description message includes at least three fields: a first field containing data identifying the RTCP message as being a type that embeds a session description message; a second field containing data that is the session description message for a media presentation; and a third field containing data identifying a length of the RTCP message, generated by summing the length of the first, second, and third fields.
