This standard includes mechanisms that allow a digital video source (such as a cable or terrestrial set-top box, digital VCR, or DVD player) to supply displayable, baseband, digital video to HDTV Monitors and EDTV Monitors (DTV Monitors), as defined in CEA Expands Definitions for Digital Television Products [16].

The timing requirements for video formats are described along with requirements for video format discovery. Also, a mechanism allowing the source device to discover all supported formats and the preferred formats of a DTV Monitor is described. Four basic video format timings from 861 are defined in this document for countries using 60 Hz. systems. Two are high definition formats (1920x1080i, 1280x720p), one is enhanced definition (720x480p), and the remaining one is standard definition (720X480i). Additionally, six new 60 Hz format timings have been added in this standard (861B). All of these new formats are optional. Their discovery is handled somewhat differently than the previously defined formats due to the desire to reduce the number of bytes used to discover formats and at the same time maintain backward compatibility with 861 and 861A. Several of the vudeo format timings (old and new) are available in two different picture aspect ratios. A method of indicating to the DTV Monitor the picture aspect ratio and colorimetry in which the video should be displayed is included. Several of the new video formats are game formats. These formats have 2880 pixels per line in the transmitted form, but the number of pixels displayed is less (based on a pixel repeat field).

For countries using 50 Hz systems, four similar video format timings from 861A have also been defined in this document. Two are high definition formats (1920x1080i, 1280x720p), one is enhanced definition (720x576p), and one is standard definition (720X576i). Additionally, six new 50 Hz format timings have been added in this standard (861B). All of these new formats are optional. Their discovery is handled somewhat differently than the previously defined formats due to the desire to reduce the number of bytes used to discover formats and at the same time maintain backward compatibility with 861 and 861A. Several of the video format timings (old and new) are available in two different picture aspect ratios. The method of indicating to the DTV Monitor the aspect ratio and colorimetry in which the video should be displayed also applies. Several of these new 50 Hz formats are also game formats.
