Embodiment Construction

[0019] The present invention is further described below in conjunction with accompanying drawing and embodiment:

[0020] Such as figure 1 As shown, a large-screen splicing controller includes a power supply, a crossover backplane, a control card and N connectors.

[0021] The connector includes an input card and an output card. The power supply supplies power to the entire large-screen splicing controller. The cross backplane is connected to the input card, output card and control card respectively. The other end of the input card is connected to the video signal collector, and the other end of the output card is connected to the For the video display, the other end of the control card is connected to the control host; among the N connectors, one connector is used as a fixed input, X connectors are used as a fixed output, and the remaining connectors can be configured as input or output.

[0022] In this embodiment, N=16, X=4, that is, in the process of configuring the numbe...

Abstract

The invention discloses a large screen splicing controller which comprises a power supply, a cross backboard, a control card and N connectors. Input cards or output cards can be inserted into the connectors, the power supply supplies power to the whole large screen splicing controller, the cross backboard realize exchange of a high-speed video single and equally distributes control information to corresponding sub cards, the input cards collect the video signals and serialize the same, the output cards perform high-speed serial signal decoding and realize a video processing function, and the control card is connected to a control host computer and controls the whole system. The invention is a processor of a hardware architecture based on FPGA, so that the utilization ratios of ports are improved, the design is flexible, and perfect synchronization of all output pictures can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a large-screen splicing controller. Background technique [0002] Image stitching controllers are widely used in municipal units and enterprises, as applications in formal occasions such as information release, real-time monitoring, and meetings. Through the control of the image splicing controller, the windowing, splitting, roaming, splicing, zooming, and multi-screen overlay of each screen can be realized. Existing image splicing controllers generally include a switching card and its connected input card, output card and control card. [0003] However, in the existing image splicing controller, the switching card occupies relatively large cost. Wherein, the number of input and output ports that any switching card can provide is usually fixed, and the number or position of its interfaces cannot be changed. This greatly limits the utilization rate of the switching car...
