It is based on packet exchange and h . 263 + standards . the client is also modified to satisfy the special traits of pda 它是一种基于包交换的视频传输,采用h . 263 +的编解码标准;并针对pda的特点,对客户端进行了优化。
At first this paper discuss the method of audio and video signal encoder , optimize the motion estimate and dct modules with mmx technology 文中首先对视音频信号的编解码方法进行了讨论,在对视音频压缩协议h 263和g
In addition , comparison is made betvveen the two libraries from another point of view and some expectation is made at the same time 此外,本文还从应用角度对所完成的两种编解码方法进行了比较,并提出对未来工作的展望。
The implementation of the convolutional code is also discussed in this paper . finally , the flow chart of the algorithms of the system is described 最后,在介绍了差错控制编码的原理后讨论了如何实现卷积码的编解码算法。
The dct / idct module and the motion estimation module which need more operation are found and optimized . and the dct / idct module is transformed to fix - point 本文对h . 263视频编解码的基本原理、系统结构和压缩方法做了简要的分析。
