Data on the Component Video Interfaces
|Publication Date:||1 October 2003|
This standard, CEA-805-A, specifies how data are carried on analog Component Video Interfaces (CVI), as described in CEA-770.1-C (for 2H 480p signals only), CEA-770.2-C (for 2H 480p signals only) and CEA-770.3C. CEA-805-A applies to all CE devices carrying data on the CVI vertical blanking interval (VBI). CEA-805-A does not apply to signals that originate in 1H 480I, as defined in CEA-770.1-C and CEA-770.2-C. All CEA-805-A references to component video and/or component video interfaces are analog only, and no reference to digital is implied.
CEA-805-A addresses the signal format and data structure of information when carried by means of the VBI of standard definition progressive and high definition YPBPR-type component video signals. It is also intended to be usable when the YPBPR signal is converted into other component video interfaces including RGB and VGA.
CEA-805-A is designed to be extensible to future data, and even future higher bandwidth data.
In addition, see Annex A (Informative) for information concerning data integrity during signal format conversions.
