[Compress-Decompress algrithms] entropy-encoding

Description: 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 compression technology in the technology section of the text in each letter is a bit different lengths (Bit) replaced. In contrast the LZ77 or LZ78 data compression method, etc., in these methods section of the original letters column is replaced by other letters. Each letter appears in accordance with its possibilities to obtain the optimal number of bits depends on the entropy. This procedure provides not only source, but also provide examples.
