Control traffic compression method

摘要

The present invention is related to method for the compression of a control traffic in media data transmission, which uses Real-time Transport Protocol (RTP) and Real-time Control Protocol (RTCP), employed particularly in real-time or near-real-time multimedia data delivery in an Internet protocol (IP) network, within the allocated fractions of the available session bandwidth. To optimise the bandwidth efficiency for RTCP traffic and the to reduce the RTCP report/feedback interval the present invention provides a method comprising the steps of initialising the context of control traffic flow by initially transmitting context parameters and updating said context during the session if necessary using compressed control packets.
