Abstract

Embodiments of the present invention relate to a digital audio-video connector and its interface, comprising at least two groups of RGB parallel buses and a group of I2S buses; each group of RGB parallel buses is used for transmission channels of video data, and each group of RGB parallel buses includes at least 24 A first pin, the signal definition on each first pin includes a 24-bits RGB data parallel bus and a 24-bits YCbCr data parallel bus; the I2S bus is used for the transmission channel of audio data, and the I2S bus includes at least 13 a second pin. Through the parallel bus signal function of the first pin of the defined RGB parallel bus and the second pin of the I2S bus, the input and output of the interface of the digital audio and video connector are set according to the function, so that the interface of the digital audio and video connector can be It is suitable for the input and output of various audio and video signals, widens the compatibility of the interface of the digital audio and video connector, and has strong versatility.

Description

technical field [0001] The invention relates to the technical field of video interfaces, in particular to a digital audio and video connector and its interface. Background technique [0002] The main function of the video interface is to output the video signal to the external equipment, or collect the video signal collected from the outside. With the continuous development of video technology, people have successively adopted various types of video interfaces in order to present high-definition and high-quality video. At the same time, the role of the video interface is also constantly enriched. [0003] In products in the field of audio and image processing, the front-end acquisition input interface or the back-end processing output interface usually include different types of video interfaces such as SDI, VGA, DisplayPort, HDMI, and DVI. These different types of video interfaces complete the decoding output Or after the encoding is input, it is connected to the video in...
