Abstract

An accurate indication of a re-synchronization point/time in streamed media content is provided to allow playout of the streamed media content from or at a desired point/time when a client or receiver switches from multimedia broadcast multicast service (MBMS) to packet switch stream (PSS) service. Various parameters, e.g., synchronization source (SSRC) and real-time protocol (RTP) timestamp, of a last received media RTP packet is signaled to a receiver. Alternatively, the SSRC and sequence number of the last received media RTP packet is signaled to the receiver, or the SSRC, the RTP timestamp, and the sequence number of the last received media RTP packet is signaled to the receiver. Also, a UTC clock time can be calculated based upon the last received real-time control protocol (RTCP) sender report (SR) and the timestamp of the last received media RTP packet in order to effectuate proper synchronization between MBMS and PSS servers.
