Note that the actual mechanism for carrying this information is different depending on the actual digital interface being used9.

Speaker allocation information to support multi-channel LPCM audio. This implies that these formats will not be supported in implementations that do not also support reception of the AVI InfoFrame Version 2.

Valid Pixel Repeat Values for each video format timing Video Codes 1 2, 3 4 5 6, 7 8, 9 10, 11 12, 13 14, 15 16 17, 18 19 20 21, 22 23, 24 25, 26 27, 28 29, 30 31 32 33 34 Video Description Xp FA — FF currently defined.

The “notch” at the lower left of each sub-pixel is the thin-film transistor. LCD shutters consist of a stack of three primary elements, on the bottom and top of the shutter are polarizer plates set at right angles. 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 used in place of the full-sized VGA connector.

Display gamma, factory default range 1. 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: For the LPCM i. 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 Monitor.

For pixel-repeated formats, this value indicates the number of pixels that shall be decimated by the receiver or repeated depending on the signal process. If the source device can determine that the sink device is compliant, then it may supply Xp since support for this format timing is required in all compliant DTV Monitors. Magnetic core memory would become the dominant form of memory until the development of transistor-based memory in the late s, developments in technology and economies of scale have made possible so-called Very Large Memory computers.

The transition to terrestrial television after the turn of the millennium left many existing television receivers unable to tune. Soviet calendar “Twenty-first year of the socialist revolution” 12 December Below Such a device would not be able to read block 2 and up.

These requirements will be spelled out in the various sections on each infoFrame, but the specific format of EDID will be covered in Section 7. In other words, it is the portion of the picture that does not contain useful information. In most cases, it is possible to identify the audio by parsing the actual audio stream e. Note that in the Data Collection Block, this payload is preceded by a Tag Code Byte that includes a tag equal to four and a length of three see Table Use of this information by the DTV Monitor is optional.

InLCD televisions surpassed sales of CRT-based televisions worldwide for the first time, LCD TVs are quickly displacing the only major competitors in the large-screen market, the plasma display panel and rear-projection television.

Extended Display Identification Data – WikiVisually

Cfa-861b Number of End of Top Bar – An unsigned integer value representing the last line of a horizontal letterbox bar area at the top of the picture. The most recent version, CTAG, cea-86b originally published in Novemberwas made cez-861b for free in November after some necessary changes due to a trademark complaint.

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. Therefore, for the purposes of this standard, the following rules apply for interlaced formats: Video card — A video card is an expansion card which generates a feed of output images to a display.

While flat-panel TVs have existed in research labs sincethey did not become the main display technology until the early s, when the technologies became affordable.

Control of closed captioning settings, programs, events, etc. The first three bits are a Tag Code.

Extended Display Identification Data

This data block can be used to include information not specifically defined in this standard. Newer physical interfaces that are expected to be backward compatible with DVI 1.

This page was last edited on 10 Decemberat Video timing parameters if byte 10 is 00 or 01padded with 0A 20 20 20 20 20 If the source device only supports basic audio, it is not required to send this information for backward compatibility with Abut it is recommended. Data Byte 4 contains information that describes how various speaker locations are allocated to transmission channels.

The first bit declares if the format is a native format of the disp. See the annexes on how to apply this standard to the individual interfaces available at the time of this writing.

For countries using 50 Hz systems, four similar video format timings from A have also been defined cea-861n this document. If needed, contents of the memory can be transferred to secondary storage.

Extended timing information type: This includes TiVo and similar DVR devices, network routers, facility automation controls, televisions, many smartphones and tablet computers run Android and other Linux derivatives.
