This standard defines the physical characteristics of an interface and the parameters of the signals carried across that interface, using three parallel channels for the interconnection of equipment operating with analog component video signals. The standard includes specifications for two scanning structures: 1H – having 525 lines, 59.94 fields/second, 2:1 interlaced, and a horizontal scanning rate of 15.734 kHz; and 2H – for doubled scanned interfaces having 525 lines, 59.94 frames per second, progressively scanned, and having a horizontal scanning rate of 31.47 kHz. Both interfaces shall be capable of either 4:3 or 16:9 aspect ratios.

Other scanning structures such as DTV/HDTV are outside the scope of this standard.

The signal characteristics are defined by a gamma-corrected component set: a luminance video and two accompanying color-difference signals.

The intended uses of this interface are:

a) To interconnect professional and consumer video devices (e.g. DVD, D-VHS) to NTSC television receivers and monitors

b) To interconnect equipment into complete, self-contained analog component systems of relatively small size.

This standard applies to signals carried on the connectors described in 10.1 and may not apply to component signals carried on other types of connectors.
