Executive Summary

Optimization of bandwidth usage for video streaming is of paramount importance in networks where low bitrate links are typical. Among the solutions proposed to address this problem is header compression. Real-Time Transport Protocol (RTP) and RTP Control Protocol (RTCP) are the major protocols responsible for the delivery of real-time media. Previously, header compression at the hardware layer and multiplexing of media frames into single RTP packets was considered sufficient for reducing the bit overhead of the RTP packets.
