Description
Technical field
The present invention relates to Display Technique field, particularly relate to a kind of mosaic screen frame data and split multistage synchronous display method.
Background technology
Mosaic screen is a complete liquid crystal splicing display unit, can use separately as display, again can be with liquid
Crystalline substance is spliced into jumbotron and uses.Demand is used, it is achieved the variable changeable large-size screen monitors function that also can diminish greatly: single screen is divided according to difference
Cut display, single screen individually shows, combination in any shows, full frame screen display liquid crystal-spliced, perpendicular, the optional compensation of framing mask or screening
Lid.
In present large screen splicing display market application, work station is often equipped with one or more video card, due to LED's
Wall block resolution is certain, and the resolution of every video card delivery the most likely can be caused to be not quite similar, thus nothing
Method is configured as unity logic screen, so will result in and shows nonsynchronous problem between video card.
Summary of the invention
A kind of mosaic screen frame data that the embodiment of the present invention provides split multistage synchronous display method, in order to solve background skill
Problem present in art, technical solution of the present invention is as follows:
A kind of mosaic screen frame data split multistage synchronous display method, including:
Use three-color LED light that the gap between liquid crystal display screen is filled with；
Each output port of selected video card is write identical EDID data；
Each output port of video card is numbered according to the display unit of mosaic screen and the three-color LED light of gap filling；
Encoder is that every frame data stamp timestamp；
Display signal and the three-color LED light of the video card output after numbering are carried out the aobvious of unity logic screen by pure hardware effort station
Show；
It is sequentially connected with by line synchro between multiple decoders, using one of them decoder as main equipment, remaining decoder
As from equipment, main equipment is to from equipment tranmitting data register signal and synchrodata, from equipment by clock signal synchronization oneself
Internal clocking；
Synchronized the timestamp of frame under process by Ethernet interacting message between multiple decoders；
Decoder sends data receiver report to encoder, and described encoder adjusts transmission rate according to the report received；
Every frame data are split into the burst of regular length by encoder, and every frame burst is identified by by incremental sequence number；
Decoder receiver module, after receiving fragment message, checks that sequence number is the most continuous, adds up packet loss, out of order message number, with
And frame timeout number；
Decoder timing sends to encoder and receives report, carries this road signal connecing during this decoder receives in report
Packet receiving sum, number of dropped packets, out of order message number, and frame timeout number；And transmission rate set-up procedure: encoder is according to reception
The report of the decoder arrived adjusts the speed sending data to this decoder.
The inventive method writes identical EDID data to each output port of selected video card, each defeated to video card
Go out port to be numbered according to the display unit of mosaic screen, solve that display nonsynchronous technical problem occurs between video card, will be every
The internal clocking of the display module in individual decoder synchronizes, and is synchronized, the most really by the frame of each decoder inter-process
Realize image synchronization to show on screen.
Detailed description of the invention
