本规程定义了用于在ANSI/SMPTE 259M中定义的525/60系统中，通过360 Mb/s串行数字接口（SDI）同步传输HD-D5压缩视频和音频数据的数据流。本规程未定义适用于通过串行数据传输接口（SDTI）SMPTE 305M传输的数据流结构。

This practice defines the data stream used for synchronous transmission of HD-D5 compressed video and audio data over 360 Mb/s serial digital interface (SDI) for the 525/60 system as defined in ANSI/SMPTE 259M. This practice does not define data stream structure applicable for transmission over the serial data transport interface (SDTI), SMPTE 305M.
