DMX 512协议是Digital Multiplex的缩写，是灯光行业数字化设备的通用信号控制协议，同时也是是一种国际协议。 　　USITT DMX512/1990是调光和灯光控制台数据传输标准，是娱乐灯光领域常用的控制协议。以前0-10V模拟控制用的比较多，现在DMX512是娱乐灯光行业最主要的控制协议。USITT DMX512/1990是由美国剧场技术协会USITT提出的。最原始的版本出版于1986年，在1990年做了修改。 (DMX 512 protocol is short for Digital Multiplex is light industry, general-purpose digital signal device control protocol, but also is an international agreement. USITT DMX512/1990 is dimming and lighting control data transmission standard, is commonly used in the field of entertainment lighting control protocol. 0-10V analog control previously used more, now is the entertainment lighting industry, the main DMX512 control protocol. USITT DMX512/1990 by the American Association of Theater Technology USITT s. The original version published in 1986, was revised in 1990.)

Wireless personal channels used by mobile communications systems and storage systems for digital multimedia data all require the implementation of error control coding methods. Demonstrating the role of coding in communication and data storage system design, this text illustrates the correct use of codes and the selection of the right code parameters. Relevant decoding techniques and their implementation are discussed in detail. Providing communication systems engineers and students with guidance in the application of error-control coding, this book emphasizes the fundamental concepts of coding theory while minimising the use of mathematical tools. * Reader-friendly approach ti coding in communication systems providing examples of encoding and decoding, information theory and criteria for code selection * Thorogh descriptions of releva)
