It is recommended that source devices e. Content, in context, could mean any or all of video, audio, Internet web pages, interactive video games. Preferred timing mode specified in descriptor block 1. In order to convey the information across the interface, a packet structure is used. These segments can either transmit or block light, an image is produced by passing light through selected segments of the liquid crystal to the viewer 5.

Like A, B is fully backward compatible with and requires the use of a backward compatible version of the interface used with e. In both of these cases, the system would have the same functionality as if both devices were only devices. The relationship of the various versions of is shown in Figure 1. Note that the potential functionality of each link is set by the lowest version of on either side of the interface.
The actual functionality depends on which options are implemented. Ver 1 Single AR support etc. Ver 2 Dual AR support etc. Vendor Unique Data optional Game formats Functionality Full A Functionality possible Full B Functionality possible Figure 1 Relationship of Different Versions of It is recommended that devices using the DTV profile defined in this standard incorporate a digital content protection system to ensure interoperability and provide protection for copy-protected content traversing uncompressed, digital, high-speed, baseband interfaces.
For DVI 1. At the time of this writing, there are two options for transmitting uncompressed digital video to the DTV Monitor. Newer physical interfaces that are expected to be backward compatible with DVI 1.
These new interfaces can each be used separately to enable the full capabilities of this standard. The table is for summary purposes only. Details of the requirements are found in the document text. Ver 1 for extra byte descriptors. Note 1: Later versions of are backward compatible with earlier versions, so later versions include all of the previous versions requirements and capabilities. Note 3: If the DTV Monitor has provided a timing descriptor for a particular video format decoded in the source, it is recommended that the source send video across the interface without performing format conversion.
If a conversion must be done, it is recommended that the conversion be to a format identified by the display as a native format. If for some reason the source cannot supply that format, the source should supply the next most preferred format, and so on to the last format advertised.
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 are defined in this document for countries using 60 Hz. Two are high definition formats xi, xp , one is enhanced definition xp , and the remaining one is standard definition Xi. Additionally, six new 60 Hz format timings have been added in this standard B.
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 and A.
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 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 A have also been defined in this document. Two are high definition formats xi, xp , one is enhanced definition xp , and one is standard definition Xi. Additionally, six new 50 Hz format timings have been added in this standard B. 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. An additional format added to B is a version based on a film frame rate Xp 24Hz. This format is available in only picture aspect ratio. The ability to send colorimetry and picture aspect ratio information to the DTV was added in A. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed in Sec.

Some of these documents are drafts of standards that may become normative references in a future release of this standard.
Active Format Description A data structure that describes what portion of the picture actually contains useful information i.
It is standardized in DVB, and is partially adopted in this standard. Note that the use of the term active in this definition is not consistent with the use of this term in other portions of this standard and most of the other documents referenced by this standard. Additional information defined in this standard related to the video being sent from a source device to a DTV Monitor.
Audio and Video. Region of the display screen that is being driven or scanned at either zero luminance or at a uniform luminance; or regions of a picture that are intended to be driven e. In other words, it is the portion of the picture that does not contain useful information. Uncompressed, two channel, digital audio. Exact parameters are determined by the interface specification used with this standard e. This standard B specifies new requirements for the use of this timing extension see Section 7.
A device that receives, decodes, and presents audio and video material that has been transmitted in a compressed form. The device can be a single unit or it can be constructed from a number of individual components e. A DTV Monitor can also be any combination of these terms.
A DTV Monitor that simultaneously supports both picture aspect ratios of a video format timing e. Simultaneous support is signified by listing both formats in the EDID data structure at the same time. A video monitor capable of displaying xp in or aspect ratios.

Some VGA connectors in personal computers provided a basic form of identification by connecting one, two or three pins to ground, but this coding was not standardized.
