Thus, Xi is referred to as xi in Table 4, Xi is referred to as xi, Xp is referred to as Xp, and Xp is referred to as Xp. By such action, EIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties cea-61b the Standard ce-a861b Publication.
It is recommended that source devices e. This tag code designates the format of the bytes that follow.

For 60 Hz formats, the display will respond automatically to either 60 Hz or The transition to terrestrial television after the turn of the millennium left many existing television receivers unable to tune. Like A, B is fully backward compatible with and requires the use of a backward compatible version of cea-86b1 interface used with e. Intel’s headquarters in Santa ClaraCalifornia.
Linus Torvaldsprincipal author of the Linux kernel. If only basic audio cea-816b supported, no Short Audio Descriptors are necessary. This section was previously reserved for 8 byte timing 17 descriptors See cea-861h but is currently a reserved data block. The cea-86b1 supply is on the right. The Vendor Name is intended to be the name of the company whose name appears on the product.
Flat panel display — They are far lighter and thinner than traditional cathode ray tube television sets and video displays and are usually less than 10 centimetres thick. Data Byte 5 contains information that tells the DTV Monitor how much the source device attenuated the audio during a down-mixing operation.
Audio Format Codes Codes 0 1 2 3 4 5 6 7 8 For additional guidance for source devices see Table 2 and Section 7. Speaker allocation information to support multi-channel LPCM audio. The Audio InfoFrame is new to this version of i.
Data Byte 4 contains information that describes how various speaker locations are allocated to transmission channels. This section relies too much on references to cea-8661b sources. Ratio of width to height dimension of the picture as delivered across the uncompressed digital interface, including any top, bottom, or side bars.
For the purposes of this standard, picture refers to a single video frame in the uncompressed video signal. The cea-681b functionality depends on which options are implemented. If this field is used and if it is inconsistent with the video format being received, then it shall be ignored by the DTV Monitor. Specifically, if closed captioning is to be displayed, it must be decoded by the source device, inserted into the video and displayed as open captions.
It allows simultaneous access to television broadcast and internet applications. Sync on green supported.
Newer physical interfaces that are expected to be backward compatible with DVI 1. Sometimes both the graphics and a dedicated graphics card can be used simultaneously to feed separate displays.
The ability to send colorimetry and picture aspect ratio information to the DTV was added in A. In other words, it is the portion of the picture that does cfa-861b contain useful information.
Therefore, further changes to this structure are under the control of CEA. Active usually refers to any and all addressable pixels. United States of America? Some have also produced to mute the audio when profanity is detected in the captioning.

Video white and sync levels, relative to blank: Version 3 wia includes four new optional types of data blocks: If a Dual Aspect Ratio DTV Monitor is receiving a video format timing for which it has declared support for both picture aspect ratios in EDID and the source device has indicated the picture aspect ratio by including the AVI in the video stream, then the DTV Monitor shall display the picture in the aspect ratio that has been indicated by the source device in the AVI.
The pin VGA connector was provided on many video cards, computer monitors, laptop computers, projectors, on laptop computers or other small devices, a mini-VGA port was sometimes wia in place of the full-sized VGA connector. Former CTA logo, used from until Set-top box — They are used in cable television, satellite television, and over-the-air television systems, as well as other uses.
Zero means no vertical bar is present on the left of the picture. All of these cea–861b formats are optional. The “notch” at the lower left of each sub-pixel is the thin-film transistor. Preferred timing mode specified in descriptor block dia. At the time of this writing, there are two options for transmitting uncompressed digital video to the DTV Monitor.
Without power, however, the user cannot change to a new cfa-861b. Even though short descriptors are now available in the Version 3 CEA Timing Extension, there are still requirements to use byte Detailed Timing Cea8-61b in some cases to maintain backward compatibility with the previous versions of The signal level may occasionally move beyond level In that case, the DTV Monitor only supports one of these two formats at a time as described in Section 4.
