CTA - EIA/CEA-861-B
A DTV Profile for Uncompressed High Speed Digital Interfaces
|Publication Date:||1 May 2002|
This standard defines video timing requirements, discovery structures, and a data transfer structure (InfoPacket) that is used for building uncompressed, baseband, digital interfaces on digital televisions (DTV) or DTV Monitors. A single physical interface is not specified, but any interface implemented must use VESA Enhanced Extended Display Identification Data Standard (VESA E-EDID) for format discovery. At the time of this writing, there are two options for transmitting uncompressed digital video to the DTV Monitor. Digital Visual Interface (DVI) and OpenLDI have been available since the initial publication of 861 and allow for 861-functionality. Newer physical interfaces that are expected to be backward compatible with DVI 1.0 and include mechanisms for the transport of CEA InfoPackets, digital audio, and YCBCR pixel data are expected to be available soon1. These new interfaces can each be used separately to enable the full capabilities of this standard. All interfaces use VESA E-EDID to describe supported video formats in a way that can be discovered by the source device.
