CEA CEA-770.2-D Document Information:
Title
Standard Definition TV Analog Component Video Interface
Consumer Electronics Association
Publication Date:
Apr 1, 2007
Scope:
CEA-770.2-D 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. CEA-770.2-D includes
specifications for: (1) 480i video format defined by 480 active
lines, 525 total lines, 2:1 interlaced at 59.94 or 60
fields/second; and, (2) 480p video format defined by 480 active
lines, 525 total lines, progressively scanned at 59.94 or 60
frames/second. Both video formats shall be capable of either 4:3 or
16:9 aspect ratios.
Table 1 presents all the permissible scanning systems of
CEA-770.2-D. A compliant interface shall implement one or more of
these permissible scanning systems. Other scanning structures such
as HDTV video formats are outside the scope of CEA-770.2-D (see
CEA-770.3-C for HDTV scanning formats).
The signal characteristics are defined by a gamma-corrected
component set: a luminance video and two accompanying
color-difference signals, see SMPTE Standard 170M Section 5.
The intended uses of this interface should be:
For interconnection between Digital Television (DTV) Set top
boxes and compatible television receivers or monitors; or
For interconnection between DTV compatible Cable TV Set top
boxes or Satellite DBS Receiver Decoders, and television receivers
or monitors; or
To interconnect equipment into complete, self-contained analog
component systems of relatively small size.
CEA-770.2-D applies to signals carried on the connectors
described in section 10 and may or may not apply to component
signals carried on other types of connectors.
