Problems solved by technology

Now, the video display of the TV wall alone cannot fully meet the needs of monitoring development. Many TV wall screens will be equipped with LED (Light Emitting Diode, light-emitting diode) displays to scroll and display real-time text information on the TV wall.

Embodiment Construction

[0022] The general idea of ​​the present invention is to use a large-screen TV wall to simulate LEDs on the top of the TV wall or any text, and can control its display text, scrolling speed, scrolling direction, font color, font size, and display area size, saving costs. Effective use of the advantages of the large screen.

[0023] The large screen obtains the display information from the main control server of the TV wall, and displays it on the large screen through the VGA interface, and the video wall decoder provides the mobile strategy and display mode. Because the TV wall decoder and the TV wall main control server simulate and output the LED input information, the LED display information can be displayed on the large screen. Direct use of TV wall displays can directly replace and be compatible with all functions and displays of LED displays. The construction cost due to the display combination matching the LED display is reduced and the space for deploying hardware is ...

Abstract

The invention discloses a method and a system for simulating LED (light emitting diode) display by a television wall, which are invented to overcome the defects that the television wall display and an LED screen in the prior art are two hardware devices and need to be deployed and arranged differently. The method comprises the following steps: S110, a television wall decoder simulates an LED display screen area at a television wall display end; S120, a television wall master control server edits display information and sets polling information; S130, the television wall master control server outputs the display information and the polling information to the television wall decoder; and S140, the television wall decoder outputs the display information and the polling information to the simulated LED display screen area of the television wall display end. When an SDK (software development kit) port accessed by LED equipment goes wrong, the defect that information cannot be displayed is avoided and the cost and space saving effects are achieved.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a video wall simulation LED display method and system. Background technique [0002] In the prior art, the video monitoring project uses the video wall as the display device, and the video wall is intuitive and convenient for monitoring, and it is convenient for the monitoring personnel to find the abnormal situation of the monitored target in real time. The TV wall for monitoring generally uses professional monitors as the display equipment, and is composed of steel plate sheet metal spray-painted walls, and some are equipped with forced exhaust cooling devices. In the field of surveillance, since video wall surveillance can only be monitored in real time and cannot be played back, it often needs to be used in conjunction with a hard disk video recorder and a video matrix to form a complete surveillance system. Now, the video display of the TV wall alone cannot fully meet the ne...
