A video monitor capable of displaying xp in This information is provided by the speaker channel allocation information in Data Byte 4. DTV Monitors shall be able to accept video whose pixel clock is accurate to within 0.

The days of the week were named after the planets in the Roman era. It illustrates some of the possibilities for the two standard picture aspect ratios 4: For the x format, there may be video at these levels; it is recommended that the full range be displayed for this format. As stated in Section 7.

The timing associated with a single frame of video. In non-repeated formats, this value is 0. The top plate has transparent electrodes deposited on it, and the plate is illuminated so that the viewer can see the images on the screen. Use of this information by the DTV Monitor is also optional. Its principle use was to indicate to the DTV Monitor the intended picture aspect ratio of a video format timing that is available in more than one picture aspect ratio.

In other words, it is the portion of the picture that does not contain useful information. Year of manufacture, less — Even though short descriptors are now available in the Version 3 CEA Timing Extension, there are still requirements to use byte Detailed Timing Descriptors in some cases to maintain backward compatibility with the previous versions of Common Active Formats active format Value Description illustration of described format 4: Note that the EDID byte detailed timing descriptor allows for the designation of an interlaced format.

Other cinema and video aspect ratios exist, but are used infrequently, in still camera photography, the most common aspect ratios are 4,3,3,2, and more recently being found in consumer cameras 16,9. Simultaneous support is signified by listing both formats in the EDID data structure at the same time.

For the purposes of the Line Number and the Pixel Number, the pixel in the upper left hand corner is considered to be in row 1, column 1. For example, in the Xp case, the pixels on each line are double-clocked. This format also assumes the pixels are double clocked to meet minimum clock speed requirements for the interface. Audio InfoFrame Data Byte Set-top box — They are used in cable television, satellite television, and over-the-air television systems, as well as other uses.

Video timing parameters if byte 10 is 00 or 01padded with 0A 20 20 20 20 20 Details of the requirements are found in the document text. The information is supplied to the source device, over the interface, upon the request of the source device.

Several of the vudeo format timings old and new are available in two different picture aspect ratios.

Advanced Timing and CEA/EIA-861B Timings

That portion of an uncompressed video signal, a compressed video stream, or a sequence on a display that constitutes a single displayable image i. If for ria reason the source cannot supply that format, the source should supply the next most preferred format, and so on to the last format advertised. Even this is not always possible, as some vendors’ graphics drivers notably those of Intel require specific registry ei to implement custom resolutions, which can make it very difficult to use the screen’s native resolution.


The table is for summary purposes only.

Monitor range limits required ASCII text monitor name requiredmonitor serial number or unstructured text 6 Additional standard timing information blocks Colour point data. The method of indicating to the DTV Monitor ceaa-861b aspect ratio and colorimetry in which the video should be displayed also applies.

For this standard, it is now mandatory that a DTV Monitor list only one picture aspect ratio of Xp Xp for 50 Hz countries and only one picture aspect ratio of Xi Xi for 50 Hz countries at a time unless it is capable of receiving and cea861b the AVI defined in Section 6.

Detailed timing descriptors, in decreasing preference order. For 60 Hz systems, the DTV Monitor shall support an additional video format timing of Xp 60 Hz in at least one of two picture aspect ratios, 4: Pixel Number of Start of Right Bar – An unsigned integer value representing the first horizontal pixel of a vertical pillar-bar area at the right side of the picture.

The flat-panel TV depicted here is from A Radeon HD with the heatsink removed, showing the major components of the card. The most recent version, CTAG, [11] originally published in Novemberwas made available for free in November after some necessary changes due to a trademark complaint.

Their purpose and use remain unchanged. The vertical and horizontal image size parameters shall contain numbers that describe the aspect ratio of the displayed video actual dimensions are preferred, but not required. From Wikipedia, the free encyclopedia.

New physical interfaces that are backward compatible with DVI 1. The preferred format is the video format listed first in the EDID data structure.
