BRWall Video Wall Controller Features And Classification

Video wall controllers are widely used in communication, power, and military command organizations, and play an essential role in providing shared information, decision support, and situation display. The following describes the main principles and precautions in the design and equipment selection of large-screen display systems for the reader's reference.

The video wall controller is an interactive multimedia system that integrates multiple information receiving and processing displays and various types of personnel operation and control. It involves many technical issues of sound and light, and also requires management coordination issues of relevant departments. At the real time, it is also inseparable from the overall structure of the exhibition hall. It is essential to focus on the requirements, focus on all aspects, and apply integrated integration techniques to achieve the desired results.

The advanced video wall controller adopts pure hardware structure design, no operating system, the whole system is an entirely closed operation, no need for computer and startup software. It is effortless and stable, and the stability is much higher than the "computer + board" based on the WINDOWS operating system. "The traditional controller for mode and embedded system design. The video wall display uses the most advanced high-speed video processing chip in the world and uses sophisticated digital image processing algorithms (de-interlacing algorithms) to process multiple video VGA images in real time. Even if the compressed picture is displayed on the projector, it is very suitable for long-term continuous and stable operation. It can be quickly started up and saved for 1 second.

(1). Information reception
The system must not only receive VGA, RGB, network computer information, but also receive wideband voice and video signals, and can perform appropriate information conversion as needed.

(2). Information display
The video wall controller can publish shared information in the form of multimedia and can display situation, text, table and video image information in different modes according to the divided areas. The required situation is clear, the resolution is high, and the text and image display is bright and stable.

(3). Preview, camera, and switch
In order to ensure the accuracy and quality of the information displayed on the large screen projection, the system must have a preview function for pre-audit of the image. A camera should be installed in the display hall to extract video images of the management control mechanism. The system should have a switch display function to meet the needs of multi-channel information display.

(4). Video conference call
The video wall displays can use the monitoring, preview, switching, communication and terminal control equipment to maintain video communication with relevant parties, and can hold a video conference call at any time.

(5). Control method
The system allows leaders, business and security personnel to centrally control in the control room, open the large screen in the mobile control and authorization control modes, open windows, select sources, project displays, adjust sound and lighting.

(6). Optimize design according to standards
The video wall controller system has complex equipment configuration, numerous cable signals, high installation process, and environmental conditions. It is necessary to follow the standardization of the machine line, electromagnetic compatibility standards, and large-screen TV wall installation requirements to carry out engineering wiring and equipment installation to ensure long-term system Stable operation.

(1) Splitting one video/VGA signal into a combination of 1X2 effects;

(2) Two different display effects can be selected through remote control/software control;

(3) Ultra-high definition image parameters brightness, contrast, chroma, smooth automatic adjustment;

(4) The output display is the display format XGA or SXGA, which directly drives the flat panel display device or the projector;

(5) There are three different edge processing techniques to achieve the best stitching effect according to different situations;

(6) It can realize 20 channels of high-definition input 16-channel high-definition output and 8GB per output card;

(7) Support inputs and outputs. Input card 4GB of independent bandwidth, each window can open 4 windows; Support input card: composite video, DVI, SD base card, VGA, HDMI;

(8)  Display memory: 48bit GDDR ×  512M  per display channel;

(9)  Support resolutions from 640×480 to 1920×1200;

(10) New generation double buffering technology and synchronization technology, distributed processor architecture;

(11) Multiple control modes: network, serial port can be superimposed and roamable, arbitrarily zoomed, cascading matrix, centralized control, hot replaceable fan, dust removal net;

(12) The built-in digital multi-screen color balance of the processor, after the digital three-primary color adjustment circuit, effectively suppresses the dispersion of the three primary colors of each projection unit, the primary colors of the three colors (red, green, and blue) are the same, thereby ensuring the freshness of each splicing unit. Consistency, the wall has no visible color difference;

(13) Reliability electronic real hardware splicing processor is the only high-speed processor capable of real-time display of full-screen dynamic real-time display VGA to UXGA following ultra-high resolution real hardware image, which is very suitable for occasions requiring a long-term continuous stable operation, 1-second Power-on quick start, maintenance-free.

(14) Expandability Maximum access to 24 channels of VGA to UXGA and 96 channels of video can be simultaneously accessed, and one of them can be selected to zoom in to the full screen.

(15) Support high-definition TV input and output, adopt modular design, increase or decrease different functional modules according to different needs. Meet your requirements with the best performance and price ratio. It can be configured to support specifications such as 2 split to 48 split according to the actual needs of users. A variety of display and window mode products provide a variety of display modes, can achieve window roaming, window overlay, zoom, picture painting tile, picture-in-picture, window perspective, and other functions, and present a variety of modes, users can also define Pre-stored mode.
