Abstract
In one embodiment, a separate surrogate monitor stream provides real-time media monitoring statistics for non-media savvy protocols. The surrogate monitor stream contains packet transmission parameters, such as sequence numbers and time stamps, for associated media packets in the non-savvy media stream. The surrogate monitor stream also contains checksums derived from the media packets. The checksums are used to correlate the packets in the surrogate monitor stream with the media packets in the media stream. The information in the surrogate monitor stream is then used in conjunction with the non-savvy media stream to provide real-time media monitoring without having to modify existing infrastructure. For example, head-end video servers do not have to add Real-time Transport Protocol (RTP) support or deal with protocol upgrades like RTP/UDP co-existence.
