一个摄影头采集板的程序，里面有好几个版本。而且图象数据采取分包发送给上位机，并有校验码等差错控制功能-a photographic plate in the first collection procedures, there are several versions. But take sub-image data sent to PC, and other error-correcting code control functions

mp3文件的格式分析，显示比一般音频解码器更加详细的信息：MPEG1/MPEG2/MPEG2.5、Layer、采样率、码率、VBR/CBR、填充位、保护位、校验信息等等，而且代码写得非常好，值得学习～

循环冗余校验CRC（Cyclic Redundancy Check）是由分组线性码的分支而来，其主要应用是二元码组。编码简单且误判概率很低，在通信系统中得到了广泛的应用。重点介绍了CRC校验的原理及其算法实现。-Cyclic Redundancy Check (Cyclic Redundancy Check) is a linear code from the branch, its main application is binary codes. Coding simple misjudgm
