Abstract

The invention discloses a full-color high-definition video control system for a light-emitting diode (LED) display screen. The full-color high-definition video control system comprises a video input module and at least one video data sending module, wherein the video input module and the at least one video data sending module are connected through a video bus. The video input module comprises a video decoding module, a video image processing module and a video bus driving module which are all sequentially in signal connection. Every video data sending module comprises a video bus buffer driving module, a video data transceiving module and a kilomega network interface module which are all sequentially in signal connection. The full-color high-definition video control system has the advantages that an LED data controller sending function and a high-definition video processor function are integrated, tape loading capability of LED pixel points in the whole control system is effectively improved by adding the number of the video data sending modules, a single video data sending module can achieve high-bit video input and processing by utilizing the parallel processing advantage, and accordingly the goal of true high-definition display is achieved.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of video image processing of LED display screens, in particular to a full-color high-definition video control system for LED display screens. [0003] 【Background technique】 [0004] With the rapid development of LED display applications, there are more and more high-definition display LED display applications, and this high-definition application method brings huge value-added returns and social benefits to display operators. [0005] Generally, the application method of LED display is: front video processor system + LED controller system (sending device card + receiving card). The front-end video processor system generally includes input interface conversion, image processing, and output interface conversion of various video image signals; the sending card of the LED controller system mainly receives the output signal of the video processor, and then converts a large number of pixels after pixel sp...
