FOREWORD This standard was developed under the auspices of the Consumer Electronics Association (CEA) Technology & Standards R4.8 DTV Interface Subcommittee. Other scanning structures for analog component interfaces are set forth in separate standards, identified by CEA-770.X notation. Users of this standard should note that, at some future time, copy protection parameters, methods and/or standards are expected to be established with which copy-protected content traversing the component video interface will be required to comply. For consumer video products, an optional multi-pin connector may be specified at a later date for inclusion of audio and control signals. At that time, this standard may be revised and given a new revision number and issue date. iii

STANDARD DEFINITION TV ANALOG COMPONENT VIDEO INTERFACE 1 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: a) For interconnection between Digital Television (DTV) Set top boxes and compatible television receivers or monitors; or b) For interconnection between DTV compatible Cable TV Set top boxes or Satellite DBS Receiver Decoders, and television receivers or monitors; or c) 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.

The signal set on this interface has no setup, so black level and blanking level are the same. 3.2 Signals The three channels of the interface are designated to carry specific signals as shown in Table 2. 2
