Abstract

The invention discloses a device for displaying a video in real time based on a DSC compression algorithm. An image segmentation module is used for segmenting an original image into a plurality of sub-images. A pixel value prediction module is used for performing parallel pixel value prediction on each pixel in each pixel group of each sub-image. A residual and pixel reconstruction module quantizes and reconstructs the residual of each pixel. An entropy coding module entropy codes each sub-image with pixels reconstructed. A code rate control module calculates the quantization coefficient of each sub-image during the entropy coding to dynamically adjust the number of bytes required for entropy coding of the pixels of each sub-image. A multichannel code stream recombination module performs multichannel code stream recombination on the DSC compressed image data corresponding to each sub-image, and transmits an obtained recombined code stream to a liquid crystal module for display. The device enables a module originally operating in a series mode to operate in a parallel mode, and increases calculation speed.

Description

technical field

[0001] The invention relates to the technical field of liquid crystal module display and testing, in particular to a device and method for real-time video display based on a DSC (Displaystream compression, display stream compression) compression algorithm. technical background

[0002] With the increasing maturity of ultra-high-definition display technology, people are no longer satisfied with the video display effect of 30 frames and 720P, and the requirements for video display with a frame rate of 60 frames and above are becoming more and more intense. However, the huge amount of data that needs to be processed for ultra-high frame rate video display requires the use of compression methods with better display effects, higher-speed transmission channels, and higher-performance display interfaces in the display system. In order to solve these problems, the VESA Association proposed the DSC compression algorithm, which has low complexity, does not affect the v...
