- 运动估计是视频编码的关键技术，其最基本的原理是利用相邻帧间的时间 相关性，通过预测来减少时间冗余度。在实际编码中，为了节省码率，并不传 输每一帧的全部数据，而是利用运动估计求出每一帧与其预测参考帧之间的差 值。运动估计越准确，差值的分布越趋近与零，差值块的能量越小，经过变换、 量化和熵编码后所产生的码流的比特位率也越少。因此，运动估计搜索的准确 程度直接影响到了编码的压缩性能。 -Motion estimation is the key to video encodin

entropy-encoding
- 视频信号熵编码源程序 熵编码法是一种进行无损数据压缩的技术，在这个技术中一段文字中的每个字母被一段不同长度的比特(Bit)所代替。与此相对的是LZ77或者LZ78等数据压缩方法，在这些方法中原文的一段字母列被其它字母取代。 每个字母按照其出现的可能性所获得的最佳比特数取决于熵。 本程序不仅提供源程序，还提供相应的实例。-Entropy coding the video signal source for entropy coding method is a lossless data

Entropy-coding-source-program
- 熵编码(entropy encoding)是一类利用数据的统计信息进行压缩的无语义数据流之无损编码。本章先介绍熵的基本概念，然后介绍香农-范诺(Shannon-Fano)编码、哈夫曼(Huffman)编码、算术编码(arithmetic coding)、行程编码(RLE)和LZW编码等常用的熵编码方法。 哈夫曼编码建议了一种将位元进位成整数的算法，但这个算法在特定情况下无法达到最佳结果。为此有人加以改进，提供最佳整数位元数。这个算法使用二叉树来设立一个编码。这个二叉树的终端节点代表被编码的字母
