Abstract

The related image process and real-time monitor circuit for full-color LED screen comprises: an audio video switch circuit to output audio and video signal respectively, wherein, the video signal passes a video process circuit, a LVDS transmitter and receiver, and a raw buffer; while the audio signal passes an audio process circuit; a format conversion circuit, a LVDS transmitter connected to a LCD, and a row buffer connected to a time-schedule control circuit. This invention is simple and high-reliable, and fit to different input signal sources.

Description

【Technical field】 [0001] The invention belongs to the technical field of audio and video image processing, monitoring and transmission of full-color LED display screens. 【Background technique】 [0002] Known full-color LED display screen (as Chinese utility model patent CN2679753Y) usually transmits computer image signal by means of a general-purpose computer and a graphics card with DVI (Digital Video Graphics Interface). In order to receive and transmit analog video signals from DVD or TV, it is usually necessary to insert a video processing card into the expansion slot of the computer. The video signal is first sent to the video processing card, and the video processing card digitally processes the input signal and sends it to the computer, and then the computer displays a designated window on the computer screen (the window corresponds to the LED display screen) through the dedicated multimedia player software. Finally, the DVI interface on the graphics card sends the v...
