Abstract

The invention discloses a video signal transmission control method and a video signal transmission system.The video signal transmission control method comprises the steps that the row pixel number value of original image data is obtained, and a first cache space is distributed according to the row pixel number value; reading the original image data line by line, obtaining and caching original line image data to the first cache space, and scaling up the original line image data according to pixel coordinates to obtain shrunk release image data; and recombining the shrunk release image data according to a rear-end screen splitting demand to generate intermediate image data, performing post-processing on the intermediate image data, and generating and outputting final image data. According to the video signal transmission control method provided by the invention, delay caused by intervention of an upper computer and relatively high storage pressure and processing pressure can be avoided, and cache occupation and cost requirements are reduced on the premise of meeting rear-end split screen requirements.

Description

technical field [0001] The invention relates to the technical field of signal processing, in particular to a video signal transmission control method and a video signal transmission system. Background technique [0002] With the development of liquid crystal display technology, the resolution and refresh rate of the display module are gradually improved. In order to meet the display resolution of 4K or more to 10K, the display module usually adopts the ultra-high-definition resolution display interface V-by-One interface to realize , the specific configuration is to perform image segmentation by receiving the segmentation requirements of V-by-One image data through the host computer, and output the image according to the protocol requirements. However, each iteration of the above process needs to divide the entire received image under the control of the host computer. On the one hand, due to the intervention of the host computer, the efficiency of the automatic processing pr...
