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:
The present invention relates to a kind of splicing, particularly relate to a kind of ultra high-definition splicing system and joining method thereof.
Background technology:
Large-size screen monitors display wall has polylith display screen to rearrange, and shows single channel or multiway images simultaneously.In order to achieve this end, just need to use splicer.Splicer is made up of input and output two parts, and input connects the image signal source of required display, exports and is connected to display screen.The function of splicer is exactly after the Iamge Segmentation needing display or synthesis process, outputs on display screen.
In existing splicing, the resolution of every road input signal can not be greater than 1 times of high definition (1920*1080 pixel), when needs display of high resolution images (being greater than 1920*1080 pixel), multiple input channel must be used, be equivalent to input multiple independently little picture, again each several part combined at output.Existing technical scheme uses the mode of sacrificing refresh rate to reach high-resolution usually, and when showing high speed dynamic image, have conditions of streaking, display effect is not good.
Summary of the invention:
In order to solve the defect existed in prior art, the invention provides a kind of ultra high-definition splicing system and joining method thereof.
The present invention adopts following technical scheme: a kind of ultra high-definition splicing system, it comprises 4 road HDMI signal input module, input signal modular converter, FPGA module, outer memory module, output signal modular converter and 2 tunnel binary channels DVI signal output module, described 4 road HDMI signal input module are connected with input signal modular converter, described input signal modular converter is connected with FPGA module, described FPGA module and outer memory module and output signal modular converter and be connected, described output signal modular converter is connected with 2 tunnel binary channels DVI signal output module.
The present invention also adopts following technical scheme: a kind of joining method of ultra high-definition splicing system, it comprises the steps:
Step one: 4 road HDMI signal inputs, are converted to rgb signal through input signal modular converter;
Step 2: rgb signal enters FPGA module, FPGA module controls the read-write to outer memory module, and exports rgb signal after carrying out data processing;
Step 3: rgb signal is converted to 2 tunnel binary channels DVI signals through output signal modular converter and outputs on screen.
Further, the flow process that described FPGA module carries out data processing is: first Gather and input signal, carry out writing buffer memory, by exterior storage Read-write Catrol module, data are stored into outer memory module, data are read, through reading buffer memory and output signal control module output rgb signal from outer memory module.
The present invention has following beneficial effect:
(1). can realize 4 road HDMI signal inputs, 2 tunnel binary channels DVI signals export;
(2). the image of maximum support 3840*2160;
(3). the frequency exporting rgb signal reaches as high as 60Hz.
