本文首先介绍了视频处理的一般原理，主要介绍了采样，变换编码，预测编码，量化，熵编码等。然后介绍了最新的视频标准MPEG主要介绍了系统体系结构，系统解码器模型，缓冲区模型规范，对象描述框架，以及场景描述和视频部分。接着介绍了DSP，介绍了它的特点，主要应用，CPU结构，-This paper first introduces the general principles of video processing, the main introduction of the sampling, transform coding, predictive coding, quantization, entropy coding. And then introduce the latest MPEG video standard introduces the system architecture, the system decoder model, the buffer model specification, the object descr iption fr a mework, as well as parts of scene descr iption and video. Then introduce the DSP, the characteristics of its introduction, the main application, CPU structure,
