摘　　要：在视频压缩标准H.26L平台上改进了单参考帧选择技术(ReferencePictureSlection),实现多参考帧选择技术(Multi-RPS),并对多个标准序列进行测试。在实验数据的基础上对比分析了基于反馈信道的差错跟踪(ErrorTracking)和单参考帧选择技术(RPS)在编码效率方面的不足,相对于单参考帧选择技术,本方法较大的提高了视频压缩的编码效率。The work in this article is based on the video compression standard H.26L. The conventional feedback based video compression reference picture selection （RPS） and error tracking have their weaknesses. Based on the testing data, we propose the technique of multiple reference picture selection （MRPS）. The data obtained from simulation tests show that our technique provides much better compression rate, compared to the single reference picture selection technique.
