better in the two YCBCR formats above.In the HDMI interface, the audio signal can use 2 to 8 channels, with a sample rate of 192KHz per channel. In addition, the HDMI interface provides a DDC display data channel, which sends configuration information and data format information to the video receiving device. The receiving device can read these E-edid enhanced extensions to display the information that ide

that uses differential transmission, it is a technology that uses the voltage difference between two pins to transmit signals.Each 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 for

Detailed explanation of the CEC FileAfter previous studies, we have mastered the CE generation process and several phases of compilation, this time, let's take a look at the management methods of component packages provided by platform builder and how to manage our own components.There is a "catalog" window on the right side of platform Builder (PB), which lists all the components available for use. We can see that there is a lot of content, now the q

Author: wogoyixikexie @ gliet 2008.12.02 I have been wondering what the smdk2440.cec file is and what role it plays. It seems that if a new driver needs to be used, a lot of information has been collected in the past, and he hasn't seen how it relates to the development driver, but you can be sure, the development of BSP must be related to him. See the Pb help document below. Take a look and explain it slowly. Platform builder User's Guide>Catalog Ove

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. TMDS: These three channels transmit R, G, b Three primar

Class D (Type D) is the newest interface type, with a further reduction in size, a double row pin design, a size similar to the miniUSB interface, and more suitable for portable and on-board equipment.
