摘　　要：在视频压缩标准H.26L平台上实现了一种改进的参考帧选择技术,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(Error Tracking)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,本方法较大地提高了视频压缩的编码效率。An improved technique for reference frame selection is implemented based on the video compression standard H.26L.There are many drawbacks in conventional feedback based video compression reference frame selection(RFS) and error tracking.Based on the tested data,the author proposes the technique of multiple reference frame selection(MRFS).The data obtained from simulation tests show that the new technique provides much better compression rate compared with the single reference frame selection technique.
