| 摘 要： | 数字视频系统是在发送端经过信源编码处理，得到压缩编码后的视频、音频码流，随后进行信源编码，需要辅助数据与控制数据的支持进行分析，本文对数字电视系统三种编码方法：1）帧内预测编码；2）帧间预测编码；3）熵编码进行分析，得到H．264编码的优势的论述，通过H．264在视频上的应用调查，阐述H．264的前景。

| Abstract: | Digital video systems that dealt with source code in the sending end obtains the video, audio stream of compressed encoded, then followed by source coding which needs the support of ancillary data and control data for analysis. Three kinds of digital TV system encoding methods are analyzed： intra-prediction encoding; interframe predictive coding and entropy eoding. The advantages of H. 264 coding are diseussed also. Through the application investigation of H. 264 in video, the article describes the prospeet of H. 264. |
