多参考帧选择技术的内存控制策略研究

本文系统分析了支持多帧预测编码的低码率视频传输标准和技术(H26L与H264),认为在视频实时通信过程中,若采用多参考帧选择技术(MRPS)进行差错控制确保通信质量,则对解码器内存中的参考帧进行有效的调度和控制数目将减少解码的算复杂度。仿真实验表明,相对于RPS技术,在相同的视频质量下,多参考帧选择技术有效降低解码算法复杂度,数据压缩效率高于传统参考帧选择技术(SRPS),略低于MRPS技术。

Study of the Memory Control Method for Multi-RPS

This paper analyzes the low bit rate video transmission standards and technologies which support multi-frame prediction encoding,such as H.26L or H.264. In the process of real-time communication in video,if use the multi-reference picture selection technique（MRPS）for error control to ensure the communication quality, the memory of the decoder reference frame number of the effective scheduling and control will reduce the computational complexity decoding. Simulation results show that compared with RPS Technology,under the same video quality,this technology reduces the complexity of decoding algorithms,data compression more efficient than conventional reference picture selection technique（SRPS）,slightly lower than MRPS technology.
