EMBEDDING A SESSION DESSION DESCRIPTION MESSAGE IN A REAL-TIME CONTROL PROTOCOL (RTCP) MESSAGE |
摘要 |
<p>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 (186) that describes a media presentation (186) being streamed to the recipient (102). The session description message (186) can be associated, for example, with one of a plurality of pieces of media content in a play list of media content (186) being streamed from the device (104) to the recipient (102). In accordance with certain aspects, an RTCP message that embeds a session description message (186) includes at least three fields: a first field containing data identifying the RTCP message as being a type that embeds a session description message (186); a second field containing data that is the session description message (186) 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.</p> |
