Now display devices such as monitors, televisions and other HDMI interface, that usually each HDMI interface has a copy of the EDID data, this data can exist in the program is initialized by the system startup process, more common practice is that each HDMI port will have an EEPROM to save the data, This EEPROM is also
I recently came into contact with the DVI high-definition digital interface and started to feel nothing, because it only serves simple applications and does not involve deep encoding research. However, I have always felt a little mysterious about the storage of its edid data. After studying it for a while, I will summarize some precautions, which is also a small experience, in fact, this is nothing technical, as long as the data is written in the pres

In addition, the HDMI interface provides a DDC display data channel, which sends configuration information and data format information to the video receiving device.

From: http://blog.csdn.net/hello_wyq/article/details/1337754 1. Introduction: DDC is a bus standard for communications between a display and a computer host. Its full name is display data chnnel. Its basic function is to display the electronic file information of the display, such as the field frequency range that can be received, manufacturer, production date, product serial number, product model, standard display mode and its parameters, supported DDC standard category, and

This means that the source end needs to be able to read edid information after 256 bytes using the segment pointer 0x60. In most cases, only 256 bytes are used for edid
Extended display identification data (coming from http://en.wikipedia.org) Extended display identification data(Edid) Is a data structure provided by a computer display to describe its capabilities to a graphics card. it is what enables a modern personal computer to know what kind of monitor is connected. edid is defined by a standard published by the Video Electronics Standards Association (VESA ). the
HDMI (19pin)/DVI (16 pin) features hot swapping detection (HPD), which serves as the basis for the host system to determine whether the HDMI/DVI sends tmds signals. HPD is a detection signal sent from the display to the Computer Host. The hot swapping detection function is to detect this event through the HPD pin of HDMI/DVI when the display and other digital dis
HPD (Hot Plug detection) is designed for hot swapping in a pair of HDMI connections. Simply put, when the sender accesses the receiver, the receiver responds to the HPD signal to the sender, and then the sender starts the DDC channel to read the edid information of the receiver, then perform HDCP interaction. If both parties have successfully authenticated, the video and audio will work normally. Otherwise,
How to obtain the edid information of a TV or monitor For basic edid knowledge, see DDC edid introduction or what's edid ?. This article describes how to use an appropriate tool to obtain the edid information of related devices. For a PC, if an external monitor or TV is conn
ArticleDirectory DDC and edid are the technical standards for display hardware. The earliest standards were born in 1994. The standard is simply to let the computer know the various specifications of the display (such as the supported resolution mode, supported refresh frequency, supported field frequency range, product model, A communication standard. In this way, when the monitor is connected to a computer, the system (Windows) can a
standard HDMI connection includes three tmds transmission channels for data transmission and an independent tmds Clock Channel to ensure the unified timing required during transmission. Each tmds channel can transmit 10-bit data streams within a clock cycle. The 10 bit data can be composed of several different encoding formats. Terms used: HDMI classifies video signals into five types: R, G, B, H, and V
transmission channels for data transmission, and 1 separate TMDS clock channels to ensure the uniform timing required for transmission. within a clock cycle, each TMDS channel can transmit 10bit of traffic. This 10bit data can be composed of several different encoding formats. Terminology used: HDMI to divide the video signal into R, G, B, H, v five kinds of signals with TMDS technology code.
