本规程也称为错误检测和处理（EDH）系统，描述了错误检测校验字和相关状态标志的生成，这些校验字和状态标志可选择性地与系统M（525/59.94）和系统B、G、H的串行数字接口结合使用，以及I（625/50）数字电视设备，使用13.5 MHz或18 MHz采样的4:2:2分量数字信号或4fsc复合数字信号。尽管最好在所有串行发射器和接收器中使用这种错误检查方法，但应认识到某些设备必须将复杂性降至最低。此外，本规程中没有任何内容应排除其在4: 2:2分量数字信号。

This practice, also known as the error detection and handling (EDH) system, describes the generation of error detection check words and related status flags to be used optionally in conjunction with the serial digital interface for system M (525/59.94) and systems B, G, H, and I (625/50) digital television equipment operating with either 13.5-MHz or 18-MHz sampled 4:2:2 component digital signals or 4fsc composite digital signals. Although it is preferred that this error-checking method be used in all serial transmitters and receivers, it is recognized that some equipment must minimize complexity. Additionally, there is nothing in this practice which should preclude its use in a parallel digital interface for 4:2:2 component digital signals.
