Abstract

The video processing module is one of the most important components of the display and control computer, providing a general video processing platform for the display and control computer. The 4-channel video processing module designed in this paper supports 4-channel 4k HDMI video input, 4-channel 4k image and video simultaneous encoding and decoding, and 4-channel 4k HDMI video signal output. Each HDMI video channel supports 9-channel picture segmentation and splicing, and each picture supports compressed video decoding with a display resolution of 1920×1080p@30fps, and the code algorithm can be configured as H.264 and H.265. The video processing module receives and sends external video data through the internal dual redundant Ethernet, which greatly improves the reliability of the system. Dual redundant Ethernet switching only takes 40ms, and the code and decode system delay only needs 180ms at 3840×2160@30fps model.
