摘　　要：文章首先对H.264/AVC标准进行了简要介绍,然后分析了H.264标准中所涉及到的关键技术:帧间预测、帧内预测、DCT变换以及熵编码技术等,重点对基于上下文自适应的二进制算术熵编码(CABAC)进行了研究。在CABAC上下文模型的建立,预编码,分析其概率模型估计及更新办法中对基于表格的二进制算术编码(利用查表方式)进行了重点研究,有效的降低算法复杂度。This article has first carried out brief introduction for H. 264/AVC standards, then, have analysed the critical technology that is concerned with in H. 264 standards： Prediction Intra-fram, Prediction Inter-fram, DCT alternate as well as Shang coding technology, playing deeply research on Context-Based Adaptive Binary Arithmetic Shang Coding, （CABAC）. In the establishment of CABAC context model, in advance coding, analysing its probability model estimate and the method of updating, the text have carried out key research for the arithmetic coding of binary based on form（use to cheek table way）, effective reduction algorithm complexity.
