Data Services on the Component Video Interfaces
|Publication Date:||1 June 2013|
This standard specifies how data services are carried on analog Component Video Interface CVI, as described in CEA-770.2 and CEA-770.3. This standard applies to all CE devices carrying data on the CVI vertical blanking interval (VBI). All references within this standard to component video and/or component video interfaces are analog only, and no reference to digital is implied.
This standard addresses the signal format and data structure of information when carried by means of the VBI of standard definition progressive and high definition YPBBBPBRB-type component video signals. It is also intended to be usable when the YPBBBPBRB signal is converted into other component video interfaces including RGB and VGA.
This standard is designed to be extensible to future data, and even future higher bandwidth data.
Although this standard specifies only how data is carried on component video interfaces, in practice, the same signals are typically present on composite video outputs. In addition, see Annex A (Informative) for information concerning data integrity during signal format conversions.
