| 摘 要： | 分析了AVS标准和MPEG-2标准中的视频码流缓冲区校验模型,阐述了视频码流缓冲区校验模型的原理,对标准中的相关规定进行了整理和总结,对标准中晦涩难懂的部分进行了解释,对标准中没有明确规定的部分提出了建议。将码流缓冲区模式分成3类,并提出了高延迟模式的概念。通过对编解码过程的分析,推导出编码器维持缓冲区不溢出的条件。

| Abstract: | In this paper,the video stream buffer checking model in AVS and MPEG-2 standard is analyzed,the principle of video stream buffer checking model is described,the relevant provisions of these standards are summarized,some parts are eaplained which are difficult to understand,and suggestions to the ambiguous part are given.The video stream buffer checking model is divided into three classes,the concept of high-delay mode is proposed,the condition is derived which keep the buffer do not overflow in the encoder after analyzing the encoding and decoding process. |
