transmission error control

Presents the data structure of MPEG-4 Video Streams, the scheme used to carry through rate control, also provides error-control method in process of MPEG-4 Video transmission over the Internet.

给出了MPEG-4视频码流在Internet上传输的码流结构，传输过程中采用的码率控制方案，并给出了进行差错控制的方法。

A Novel and Relatively Better Combined Error Control Scheme of Video Transmission over Wireless Network

无线信道下视频传输的组合式差错控制机制

Existing systems commonly used serial communication. Different systems make different definitions of data format, transmission speed, transmission steps, error correction mode and control characters. The nonstandard communication protocol causes problems of poor compatibility.

现有系统普遍采用串行通信，不同的系统对数据格式、传送速度、传送步骤、纠错方式以及控制字符定义等问题做出的规定并不统一，存在通信协议不规范、兼容性差的问题。

Serial transmission protocal of 3-wire model with tolerable error ability, the method of transition to save electricity state and time control output realization is also described.

在此基础上，成功地给出了具有容错能力的三线制串行传输协议、省电模式转换方法及时间控制输出的实现方案。

The control of transmission ratio is done by this principle in the bench test. The result showed that the rapidity and accuracy is good and the dynamic follow error is small.

进行了传动比控制台架试验，达到了快速性和准确性好、动态跟踪误差小的效果。
