Embodiment Construction

[0016] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] figure 1 It is a block diagram of a multi-screen splicing system based on the FC-AV protocol, such as figure 1 As shown, the multi-screen splicing system based on FC-AV protocol includes: upper computer, video integration and distribution controller, optical fiber and receiving controller. Among them, the upper computer is the video source scheduling control terminal of the whole system, and the video display command is issued by the user operation. The video integration and distribution controller is responsible for decoding multiple types of video data into RGB pixel data, processing and packaging them into multiple FC-AV data frames according to the instructions of the host computer, and transmitting them to...

Abstract

The invention relates to a multi-screen splicing system based on an FC-AV protocol, and the system comprises an upper computer, a video integration and distribution controller, an optical fiber, and areceiving controller. The upper computer is a video source scheduling control end of the whole system; a video display command is issued by user operation; the video integration and distribution controller is responsible for decoding multiple types of video data into RGB pixel data, processing and packaging the RGB pixel data into a plurality of FC-AV data frames according to instructions of an upper computer and remotely transmitting the FC-AV data frames to the receiving end through optical fibers, and the receiving end identifies frame header numbers to receive the corresponding FC-AV dataframes and converts the data into video signals to be displayed. According to the multi-screen splicing system based on the FC-AV protocol, based on server video coding of the IP protocol, the code stream coding rate is 4Mbps at most; the FPGA coding rate based on the FC-AV protocol takes a pixel clock as a reference and is as high as dozens of megabytes to more than one hundred megabytes. And the video is not compressed, and high-bandwidth, high-reliability, low-delay and long-distance lossless transmission of the video can be realized without compressing the video.

Description

technical field [0001] The invention designs a long-distance transmission technology of multi-channel and multi-type videos, and in particular relates to a multi-screen splicing system based on the FC-AV protocol. Background technique [0002] LCD large-screen splicing display technology is an emerging technology, which is composed of multiple LCD screens, which can be arranged to display the required display size arbitrarily, with high brightness, high contrast, high color saturation, high color uniformity, long life, average Long trouble-free time and low cost. At present, it is widely used in large-screen display systems such as security monitoring, information release, and advertisement display. At present, there is a certain gap in the multi-screen splicing system based on the FC-AV protocol. Contents of the invention [0003] The purpose of the present invention is to provide a multi-screen splicing system based on the FC-AV protocol, which is used to solve the abo...
