Abstract

The invention discloses a large-scale video matrix exchange board and video processing board connecting structure which comprises a video matrix switching board, a video input-output processing board and a video channel connecting board. A first video channel connector is mounted at the upper end of one edge of the video channel connecting board and connected with the video matrix switching board, and two second video channel connectors are mounted in the middle of the other edge of the video channel connecting board and connected with the video input-output processing board. The connecting structure can realize a matrix function while having reasonable heat channels for heat radiation, input-output board cards are compatible with board cards for small-scale matrix cabinets, and the connecting structure does not need to be designed solely, thereby being reasonable in structure.

Description

Technical field [0001] The invention relates to a connection method of a video matrix channel switch board and a video input and output board, in particular to a connection structure of a large-scale video matrix switch board with more than 128 channels and a video processing board. Background technique [0002] At present, the market demand in the video industry is gradually developing towards ultra-high definition. The connection between the existing large-scale video matrix product video matrix channel switch board and the video input output board is mainly to use the matrix channel switch board to add a channel wiring extension board in parallel and connect it with the video input output board, making the two The PCB boards are very close to each other, and the video input and output boards are also horizontally inserted. [0003] Since the ultra-high-definition video matrix needs to process more video information, the power consumption of the matrix channel switching chip and...
