Ultra-high-definition splicing system and splicing method thereof

Abstract

The invention discloses an ultra-high-definition splicing system and a splicing method thereof. The splicing method comprises the following steps of (1) inputting four channels of HDMI (high-definition multimedia interface) signals and converting the HDMI signals into RGB (red, green, blue) signals by using an inputting signal conversion module; (2) transmitting the RGB signals in an FPGA (field programmable gate array) module which controls reading and writing on an external storage module and outputting the RGB signals after data processing is performed; and (3) converting the RGB signals into two channels of dual-channel DVI (digital video interactive) signals by using an outputting signal converting module and outputting the two channels of dual-channel DVI signals to a screen. By an ultra-high-definition splicing technology, the four channels of HDMI signals (1920*1080@60Hz) are inputted, after the four channels of HDMI signals are processed by software and hardware, the two channels of dual-channel DVI signals are outputted, the resolution ratio of an optional channel of DVI signals can reach 1920*2160@60Hz, and the maximum display resolution ratio of the whole screen can reach 3840*2160@60Hz.

Description

Technical field: [0001] The invention relates to a splicing technology, in particular to an ultra-high-definition splicing system and a splicing method thereof. Background technique: [0002] The large-screen display wall is composed of multiple display screens arranged to display single or multiple images at the same time. To achieve this, a splicer is required. The splicer is composed of input and output. The input is connected to the image signal source to be displayed, and the output is connected to the display. The function of the splicer is to divide or synthesize the image to be displayed and then output it to the display screen. [0003] In the existing splicing technology, the resolution of each input signal cannot be greater than 1 times high-definition (1920*1080 pixels), when it is necessary to display high-resolution images (greater than 1920*1080 pixels), multiple input channels must be used, which is quite It is better to input multiple independent small pi...

Problems solved by technology

[0003] In the existing splicing technology, the resolution of each input signal cannot be greater than 1 times high-definition (1920*1080 pixels). When it is necessary to display high-resolution images (greater than 1920*1080 pixels), multiple input channels must be used, which is equivalent to It is better to input multiple independent small pictures, and then synthesize the parts at the output end

Existing technical solutions usually use the method of sacrificing the refresh rate to achieve high resolution. When displaying high-speed dynamic images, there will be smearing and the display effect is not good.
