摘要
A method for monitoring QoS in H.264 multimedia communication, which can realize the monitor of H.264 multimedia communication in band and reduce the extra expend of QoS monitor. The method uses the extension information mechanism of high layer media protocol H.264 itself to carry QoS report directly, and avoids using extra bandwidth, and realizes a "in band" QoS report mechanism; using extension information mechanism of H.264 such as SEI information and user self-defined data to transmit QoS report and monitoring transmission quality of H.264 multimedia communication can reduce extra bandwidth expend without affecting the communication of the existing H.264 protocol device; the method provides multiple protection measures to improve the reliability of RTCP/UDP based on the H.264 in band report.
