摘　　要：This paper introduces the hierarchical system structure of H.264,and analyses the video coding layer(VCL)of the H.264 Baseline.Some key modules in the realization scheme have been deeply analyzed such as intra prediction,inter prediction,integer DCT,quantization,entropy coding,and deblocking fi lter.We point out two encapsulations format of the coded data in network abstraction layer(NAL):ordinal byte stream encapsulation in circuit exchange net,and RTP pack encapsulation in IP network.This paper introduces the hierarchical system structure of H.264,and analyses the video coding layer(VCL)of the H.264 Baseline.Some key modules in the realization scheme have been deeply analyzed such as intra prediction,inter prediction,integer DCT,quantization,entropy coding,and deblocking fi lter.We point out two encapsulations format of the coded data in network abstraction layer(NAL):ordinal byte stream encapsulation in circuit exchange net,and RTP pack encapsulation in IP network.
