Patent ID: 8068515

Claim:
A computer-implemented method, comprising: receiving, by a computing device having a processor and a memory, from a server, an RTCP packet that contains timestamp conversion information for a broadcast which comprises at least two related real-time media streams, wherein the timestamp conversion information includes an RTP timestamp and a corresponding common timestamp used to synchronize media content transferred in the at least two real-time media streams of the broadcast; storing the RTCP packet in the memory of the computing device; receiving a multicast join request addressed to the server, wherein the multicast join request is sent by a client for the broadcast containing the at least two real-time media streams; and sending, by operation of the processor on the computing device, the stored RTCP packet stored in the memory of the computing device for the at least two real-time media streams to the client, based on receiving the multicast join request, wherein the client is configured to synchronize the media content transferred in the at least two real-time media streams of the broadcast using the timestamp conversion information of the stored RTCP packet.
