Abstract
The invention provides an information display technology of a spliced large screen. The technology comprises a signal source, a large screen controller, a local display terminal and a spliced large screen. The method comprises the following steps: (a) acquiring signals of a computer terminal and a video pick-up terminal; (b) synthesizing the acquired multi-channel signals into one-channel signals by utilizing the large screen controller; (c) and processing and outputting the signals as RGB or DVI signals, wherein the output signals in one channel are transmitted to the spliced large screen to be displayed through a VGA or DVI data line, and the output signals in the other channel are converted into GVA signals and then transmitted to the local display terminal to be displayed. In the invention, multi-channel signals from the signal source are synthesized into one-channel signals by utilizing the large screen controller, and special control software is utilized to dynamically adjust the displayed information of the signal source, thereby displaying information of the spliced large screen at the local display terminal in real time and ensuring the resolution and real-time performance of the displayed information.
Description
Technical field
The invention belongs to field of information display, relate in particular to a kind of splicing large screen information display technology.
Background technology
Tradition splicing large screen information display technology adopts following dual mode to realize: first kind is by grabbing after the screen, to institute's extracting information Network Transmission, send local display terminal to, be used for the display splicing big screen information, the frame per second of signal is very low like this, even signal of ability demonstration in several seconds, so can only show static effect; Second kind is that input signal is intercepted, and intercepts a part of signal and sends local display terminal to, is used for the display splicing big screen information, and this mode can only realize the demonstration to the splicing large screen one-channel signal, can't realize full screen synchronously.
Summary of the invention
In order to solve the asynchronous of traditional splicing large screen information display technology and the problem that can only show one-channel signal, the present invention proposes a kind of splicing large screen information display technology, this invention can guarantee splicing large screen information under the situation of not losing sharpness and real-time, and the information of splicing large screen is shown to local display terminal fully.
The invention provides a kind of splicing large screen information display technology, comprise the steps:
A) collecting computer terminal and video camera terminal signaling;
B) utilize described giant-screen controller to finish synthetic one tunnel Signal Processing of multiple signals to the described signal that collects;
C) described signal Processing is output as RGB or DVI signal, described output signal one tunnel sends to the splicing large screen demonstration through VGA or DVI data line, and another road converts the VGA signal to, sends to local display terminal and shows.
For solving processing to various signal source informations, described giant-screen controller uses special-purpose Control Software that the displaying contents to various signal sources is dynamically adjusted by Computer Graphics technology and Compute Unified Device Architecture hardware design framework.
The invention has the beneficial effects as follows, by the giant-screen controller multiple signals are synthesized one tunnel Signal Processing, show for splicing large screen, and send local display terminal to, this invention has guaranteed that splicing large screen information can obtain well showing in real time to splicing large screen information at local display terminal under the situation of not losing sharpness and real-time.The asynchronous of traditional splicing large screen information display technology and the problem that can only show one-channel signal have been solved.

Embodiment
As shown in Figure 2, a kind of splicing large screen information display technology, its system comprises signal source 1, giant-screen controller 2, local display terminal 3 and splicing large screen 4; Its method comprises the steps:
A) collecting computer terminal and video camera terminal signaling source 1;
B) the described signal source 1 to collecting utilizes giant-screen controller 2 to finish synthetic one tunnel Signal Processing of multiple signals;
C) after 2 pairs of described signal sources 1 of giant-screen controller are handled, output RGB or DVI signal, one tunnel process VGA or DVI data line send to splicing large screen 3 and show;
D) to the signal of giant-screen controller in the step c) 2 output, another road converts the VGA signal to, sends to local display terminal and is used for the information of display splicing giant-screen 4.
By above embodiment, the present invention has realized splicing large screen information under the situation of not losing sharpness and real-time, and the information of splicing large screen is shown at local display terminal fully.The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
