针对移动多媒体通信的可靠性和并行多流的实时性保障问题,通过组建GOP分帧协作网络,提出了多媒体多流并行动态传输机制。首先,基于多媒体流结构和视频帧优先级与吞吐率、可解码帧率和信道质量的关系,提出了GOP分帧协作传输网络的构建和动态调整方案。其次,基于动态多媒体的状态分析了多媒体流数、信道质量、可解码帧率和误码率的变化规律,结合用户侧需求和通信距离,提出了基于GOP分帧协作的动态多媒体多流并行传输机制。最后,仿真实验证明了所提方案在实时性、并行效率和可靠性等方面具有良好表现,非常适合于并行大规模多媒体实时通信。

英文摘要：

According to the reliability of mobile multimedia communication and the real-time security of parallel multi stream, a multi stream parallel dynamic transmission mechanism based on GOP is proposed. Firstly, based on the multimedia stream structure and video frame priority, the construction and dynamic adjustment scheme of the GOP sub frame cooperative transmission network is proposed. Secondly, the dynamic state analysis based on the multimedia stream number, channel quality, variation of decodable frame ratio and bit error rate is given, and a dynamic multimedia transmission mechanism based on GOP Frames Cooperation is proposed. Finally, the simulation results show that the proposed scheme has good performance in real-time, parallel efficiency and reliability, and is very suitable for parallel large-scale multimedia real-time communication.
