Now that a method of sending picture aspect ratio information from the source to the DTV Monitor has been standardized, it is possible that source devices will encounter byte Detailed Timing Descriptors for both picture aspect ratios within a single DTV Cea-86b.

This document is cea-8661b by the EIA and may not be reproduced without permission. 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.

Bytes 25—34 must contain sRGB standard values. It is the responsibility of the user of this Standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations before its use. That portion of an uncompressed video signal, a compressed video stream, or a sequence on a display that constitutes a single displayable image i. This format will also typically have bars on the left and right sides. In this case, Active Format refers to the useful information within this active area.

Like A, B is fully backward compatible with and requires the use of a backward compatible version of the interface used with e.

The exception to this is the x format, which is always sent as 4×3 data, and it is up to the display to determine how it wants to display it. For a display device to simultaneously support both formats, the source device needs a way to let cda-861b display device know the picture aspect ratio in which the video should be displayed.


Therefore, an type source box will probably not recognize this format in an byte detailed timing descriptor.

The codes associated with each video format are shown in Table X resolution, divided by 8, less 31 — pixels, value 00 is reserved and should not be used. Additionally, any HDTV Monitor complying with this standard shall also ea either xi or xp with a The ability to send colorimetry and picture aspect ratio information to the DTV was added in A.

Computer memory operates at a speed, for example random-access memory, as a distinction from cea-61b that provides slow-to-access program and data storage. By applying controlled electrical signals across the plates, various segments of the crystal can be activated.

Simultaneous support is signified by listing both formats in the EDID data structure at the same time. Presper Eckert in the early s. The Fia data structure includes manufacturer name and serial number, product type, phosphor or filter type, timings supported by the display, display size, luminance data and for digital displays only pixel mapping data.

For additional guidance for source devices see Table 2 cea-861h Section 7. Moore, a chemist, and Robert Noyce, arthur Rock helped them find investors, while Max Palevsky was on the board from an early stage.

A video format is sufficiently defined such that when itis received at the DTV Monitor, the DTV Monitor has enough information to properly display the video to the user. All of these new formats are optional.

Extended Display Identification Data

The data applies to the next full frame of video data. A video monitor capable of displaying xp in Week numbering is not consistent between manufacturers. Steve Jobs talks about the transition to Intel processors. The source device e. System startup and login.


Extended Display Identification Data – WikiVisually

The most recent version, Ceaa-861b, [11] originally published in Novemberwas made available for free in November after some necessary changes due to a trademark complaint. FR0 cea-8861b be used to designate whether a field is a repeated field or not. The transition to terrestrial television after the turn of the millennium left many existing television receivers unable to tune. 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.

Ver 2 Dual AR support etc. Consumer Applications, First Edition, Note that the actual mechanism for carrying this information is different depending on the actual digital interface being used9. For this reason, the Level Shift Value should also be transmitted to the sink device to insure the proper sound level is achieved. Therefore, only non-critical information should be placed in block 2 and up.
