Title
Data Services on the Component Video Interfaces

Consumer Electronics Association

Publication Date:
Nov 1, 2008

Scope:

This standard, CEA-805-D, specifies how data services are carried on analog Component Video Interfaces (CVI), as described in CEA-770.2-C and CEA-770.3-C. CEA-805-D applies to all CE devices carrying data on the CVI vertical blanking interval (VBI). All CEA-805-D references to component video and/or component video interfaces are analog only, and no reference to digital is implied.

CEA-805-D addresses the signal format and data structure of information when carried by means of the VBI of standard definition progressive and high definition YP_BP_R-type component video signals. It is also intended to be usable when the YP_BP_R signal is converted into other component video interfaces including RGB and VGA.

CEA-805-D is designed to be extensible to future data, and even future higher bandwidth data.

Although CEA-805-D specifies only how data is carried on 480i component video interfaces, in practice, the same signals are typically present on 480i composite video outputs. In addition, see Annex A (Informative) for information concerning data integrity during signal format conversions.
