SDI
SDI接口是数字串行接口(serial digital interface)的首字母缩写。 串行接口是把数据字的各个比特以及相应的数据通过单一通道顺序传送的接口。由于串行数字信号的数据率很高，在传送前必须经过处理。
HDMI
HDMI，高清晰度多媒体接口(英文：High Definition Multimedia Interface)是一种全数位化影像和声音传送接口，可以传送无压缩的音频信号及视频信号。HDMI可用于机顶盒、DVD播放机、个人电脑、电视游乐器、综合扩大机、数位音响与电视机。HDMI可以同时传送音频和影音信号，由于音频和视频信号采用同一条电缆，大大简化了系统的安装。
二、应用领域
广泛用于使用SDI信号的各级电视台的播出机房和非编制作领域，也广泛用于各种使用HDMI接口的光端传输领域。
