本规程定义了使用三个平行通道的接口的物理特性，用于连接使用模拟分量HDTV信号运行的设备。对于SMPTE 240M-1995，通过该接口传输的信号具有1125行、每秒60.00场、16:9纵横比和2:1交错的扫描结构。该接口也适用于具有其他扫描结构的HDTV信号。该接口的预期用途是:-在较大的组件岛或工厂内，互连使用相同组件集的并行模拟HDTV视频子系统的元件。组件HDTV编辑和后期制作套件就是此类子系统的示例；-将设备互连成尺寸相对较小的完整、独立的HDTV模拟组件系统。本规程适用于第7节所述连接器上携带的信号。 1和可能不适用于其他类型连接器上携带的部件信号。本规程还定义了接口上的首选分量视频信号，包括其波形结构和电平。

This practice defines the physical characteristics of an interface using three parallel channels for the interconnection of equipment operating with analog component HDTV signals. For SMPTE 240M-1995, the signals carried across this interface have a scanning structure of 1125 lines, 60.00 fields per second, 16:9 aspect ratio, and 2:1 interlace. This interface is also appropriate for HDTV signals having other scanning structures.The intended uses of this interface are:- to interconnect the elements of parallel analog HDTV video subsystems which use the same component sets within larger component islands or plants. Component HDTV editing and post-production suites are examples of such subsystems;- to interconnect equipment into complete, self-contained HDTV analog component systems of relatively small size.This practice applies to signals carried on the connectors described in 7.1 and may not apply to component signals carried on other types of connectors. The practice also defines the preferred component video signals across the interface, including their waveform structure and levels.
