Abstract

The invention provides a digital high-definition display controlling device and a method thereof. The method comprises the steps that: a DVI interface module accesses an external video signal and inputs the external video signal to a screen capturing module; the screen capturing module captures the video signal according to a HDTV resolution ratio standard of 1280 multiplied by 720 and transmits the video signal after capturing to a data reorganization module which carries out data reorganization to the video signal and inputs the signal after reorganization to a ping pong storage controlling module which carries out caching storage process to the video data after reorganization and causes the video data to be output continuously to a data distribution module by an HDTV frame frequency of 60Hz; and the data distribution module adjusts the output sequence of the video data and outputs the video data to an LED lattice screen. The device and the method can cause the displaying result of the LED lattice screen to reach an HDTV displaying standard of 1280 multiplied by 720 at 60Hz.

Description

Technical field: [0001] The invention relates to high-definition digital television output technology (HDTV), in particular to a high-definition display control device and method for LED dot matrix screens. Background technique: [0002] High definition digital television output technology (HDTV, High Definition Television) technology is a television system that uses digital signal transmission. It realizes digitalization from video collection, production to video transmission, and to user terminal reception, so HDTV brings us extremely high definition, its resolution can reach up to 1920×1080, and the frame rate can reach 60fps , Compared with traditional analog TV, digital TV using HDTV technology has many advantages such as high-definition picture, high-fidelity stereo sound, TV signal can be stored, multimedia system can be completed with computer, and frequency resources are fully utilized. [0003] The biggest feature of HDTV is high-definition, but most of the rear p...
