scope:

This standard defines the physical characteristicosf an interfacea nd the parameters of the signals carried across that interface, using threep arallel channels for the interconnectiono f equipment operating with analog component video signals. This standard includes specifications for: (1) 480i video format defined by 480 active lines, 525to tal lines, 2:l interfaced at 59.94 or 60 fields/second; and,( 2) 480p video format defined by 480 active lines, 525t otal lines, progressively scanned at 59.94 or 6fr0a medsecond. Both video formats shall be capabolef either 4:3 or 16:9 aspect ratios.

Table 1 presents all the permissible scanning systems othf is standard. A compliant interface shall implement one or moreo f these permissible scanning systems. Other scanning structures sausc hH DlV video formats are outside the scopeo f this standard (for example, see EIA-770.3 for HDTV scanning formats).

The signal characteristicsa re defined by a gamma-corrected componenet set : a luminance video and two accompanying color-difference signals, see SMPTE Standard 170M section 5.

The intended uses of this interface should be:

a) For interconnection between Digital Television (Dm) Set top boxes and compatible television receivers or monitors; or

b) For interconnection between HDTV compatible Cable TV Set top boxes or Satellite DBS Receiver Decoders, and television receivers or monitors;or

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