Patent ID: 7835406

Claim:
A method comprising: receiving media packets for a media stream, wherein the media packets are User Datagram Protocol (UDP) packets that contain UDP media payloads and do not contain Real-Time Protocol (RTP) transmission parameters; generating checksums for at least portions of the media packets with a processing element; generating RTP transmission parameters for the media packets with the processing element; combining the RTP transmission parameters with the checksums for the same media packets into monitor packets; forwarding the received media packets in the media stream to one or more receivers, wherein the media packets are forwarded by the processing element separately from any RTP transmission parameters generated for the media packets; and transmitting the monitor packets that include the RTP transmission parameters for the media packets as a separate monitor stream for the media stream separately from media in the media packet, wherein both the media stream and monitor stream are sent by the processing element to at least some of the same receivers so Real-Time Control Protocol (RTCP) packet reports for the media stream can be derived using the RTP transmission parameters from the monitor stream.
