Ali current video coding standards such as h . 263 + employ variable length codes ( vlc ) , to achieve high compression efficiency 在现在流行的视频编码标准中(例如h 263 + )均使用可变长编码( vlc )来获得高效的压缩比。
This will be begged that the image compression technology not only have good compression efficiency but also can handle nimbly the compression code rate 这就要求图像压缩技术不仅要有良好的压缩效率,而且还可以灵活处理压缩码率。
Through large amount of experiments , we conclude that the video compressing program can a chieve higher compression efficiency after using the improved algorithm 因此,在本文的最后,作者对视频压缩算法的进一步改进策略进行了研究。
Moreover , we use prediction coding process to achieve high compression efficiency , error data still cause errors to propagate in the temporal direction 而且,由于编码器利用帧间预测来降低数据量,导致错误数据又会在时间域上进行扩散。
Compared with the existing header compression scheme , rfc3095 ( rohc ) has the highest compression efficiency and the best robustness and is suitable for wireless links 在现有的头部压缩协议中,以rfc3095 ( rohc )压缩效率和健壮性最高,最适合于无线链路的使用。
