说明：  详尽地论述了H.264 特点、编码器原理、解码器原理、编解码器的实现。为了更好地理解H.264 编解码原理及其实现，第7 章详细介绍了H.264 码流的句法和语义。最后对H.264 视频编码传输的QoS 进行了专门地论述。
(H.264 are discussed in detail the characteristics of the principle of encoders, decoders principle, the realization of codec. To better understand the H.264 codec principle and its realization, Chapter 7 details H.264 bitstream syntax and semantics. Finally, H.264 video encoding transmission QoS for a special discussion.)
