Abstract
The present invention provide a kind of realize that 4K ultra high-definition video input output rings are held high office the method that shows, solve the problems, such as on market without the logical scheme of DP input and output ring.The present invention transfers to data link processes after the data-reusing by DP multiplexers by signal all the way, while other data ring all the way leads to gives DP output interfaces.The link processing of DP input and output ring messengers is so can achieve, and data are without the source natural disposition for postponing and ensureing data.
Description
Technical field
This patent is related to a kind of method for processing video frequency.
Background technology
At this stage, liquid crystal display is due to having lightweight, small volume, little power consumption, radiating low, good quality
The advantages of, have been widely used in the individual consumer's goods such as notebook computer, computer monitor, TV.
Liquid crystal panel can be equipped with the driving plate of liquid crystal itself when dispatching from the factory, but due to lcd applications
Occasion is different, may require that the various types of interface of coupling (such as USB interface, AV interfaces,
DVI interface, HDMI (or DVI interface), DP interfaces etc.), so also needing to increase by one
Decoding deck is completing the decoding of all signals.
Decoding deck on current China market, primary solutions are provided for MStar.MStar
Decoding scheme be mainly directed towards TV market, with low price, the features such as supporting interface is more.In addition
Also a lot of video IC companies, there is provided various types of decoding scheme.
In the decoding scheme that all markets provide at present, do not support that DP input and output ring leads to scheme.
There is DP interfaces the characteristic of high bandwidth, single channel video input to support 1920*1080@120Hz refresh rates
With 3840*2160@30Hz refresh rates.For ultra high-definition signal and 3D signals transmission provide very good
Solution.
Content of the invention
It is an object of the invention to solving the defect of prior art, there is provided one kind realizes 4K ultra high-definition videos
Input and output ring is held high office the method that shows.
For achieving the above object, the present invention is employed the following technical solutions：
A kind of realize that 4K ultra high-definition video input output rings are held high office the method that shows, be input into (1) including DP
With DP output interfaces (2), after video data input, by data link processes (3), then pass through
Input mixer (4), then by image procossing (5), exports to display screen finally by LVDS,
Data are led to next display screen also by DP output interface rings simultaneously, and signal processing is without delay,
Without black field.
After the DP interfaces input data, data are divided into two by data multiplexer, all the way to number
Color adjustment is done according to link, data are split, adjustment etc. is processed and then by LVDS to currently displaying screen,
In addition lead up to multiplexer without postpone to DP output rings lead to next display screen DP input connect
Mouthful, by the logical data link of this ring by data publication to each display screen, and it is complete to synthesize display one
Into data display.
It is 1920*1080@120Hz that the described DP input and output rings connect the highest resolution of mouth support
With 3840*2160@30Hz.
Description of the drawings
Fig. 1 is common decoder plate data processing schematic diagram；
Fig. 2 is the decoding deck data processing schematic diagram of the present invention；
Wherein：1-DP input interfaces, 2-DP output interfaces, 3- data link processes, 4- input mixing
Device, 5- image procossings.
Specific embodiment
Describe the present invention below in conjunction with the accompanying drawings：
As shown in figure 1, the data processing schematic diagram for common decoder plate.Distinct interface is (as VGA connects
Mouth, DP interfaces, HDMI (or DVI interface) and DVI interface etc.) data output after, lead to
Corresponding data link processes are crossed, view data mixing, Ran Houtong are carried out by input mixer then
Image procossing is crossed, is finally exported by LVDS.
The present invention transfers to data link processes after the data-reusing by DP multiplexers by signal all the way, with
When in addition data ring leads to and gives DP output interfaces all the way.DP input and output ring messenger so can achieve
Link processing, and data without postpone and ensure data source natural disposition.
Claims (1)
1. a kind of realize that 4K ultra high-definition video rings are held high office the method that shows, it is characterised in that：Defeated including DP
Incoming interface (1), DP output interfaces (2), after the input of DP video datas, by data link processes
(3), then by input mixer (4), then by image procossing (5), finally by LVDS
Export to display screen, also DP loop-through outputs lead to input to the ring of next monitor.The logical input of this ring
1920x1080@120Hz or 3840x2160@30Hz resolution is supported in output, without
Outside allotter or matrix, you can realize that the distribution of data shows.
