Image switching and splicing display system based on high-speed data bus

Abstract

The invention discloses an image switching and splicing display system based on a high-speed data bus. The image switching and splicing display system is characterized by comprising an input plate and an output plate, wherein the output plate is connected with the input plate; the input plate includes multiple signal input single plates successively connected; the output plate includes multiple signal output single plates successively connected; and the last signal input single plate is connected with the first signal output single plate. According to the image switching and splicing display system disclosed by the invention, the structure is simple, the system flexibility is stronger, the cost and the system power consumption are simultaneously reduced, the system performance is more stable, and the maintenance is more convenient; the image processing of the invention can be multistage processing, so an image processing function is stronger; and thus, the functions such as image switching, segmenting, splicing, windowing and the like can be realized; and the image switching and splicing display system is applied to promotion and application.

Description

technical field [0001] The invention relates to an image display system, in particular to an image switching and splicing display system based on a high-speed data bus. Background technique [0002] The method of using the backplane to transmit image data in the existing high-definition video switching and splicing technology is realized based on a high-speed serial video data bus (generally SEDERS or LVDS) and a bus switching chip (CROSS POINT). Video signals (DVI, HDMI, VGA, etc.) are converted into high-speed serial video data (usually SEDERS or LVDS), and then the bus switching chip (CROSS POINT) is used to realize video exchange, and finally FPGA devices are used to convert high-speed serial video data Output high-definition image signals such as DVI, HDMI, VGA, etc., and realize image splicing and window display. The limitations of this system are reflected in the following aspects: [0003] (1) In terms of product flexibility: using a bus switching chip to achieve bu...

AI Technical Summary

Problems solved by technology

[0003] (1) In terms of product flexibility: using a bus switching chip to achieve bus data switching is less flexible, and the chip itself cannot perform further operations on the bus data;

[0004] (2) Backplane structure: the bus switching chip will occupy certain wiring and layout resources, and the use of the bus switching chip will also increase the power consumption of the system and reduce the overall reliability of the system;

[0005] (3) In terms of cost: the cost of the bus switching chip is relatively high, which will increase the system cost
