External splicing controller LCD splicing device

1. Description of splicing system

Multi-screen multi-window image mosaic processor is a professional high-end high-definition image mosaic processing equipment, which can display multiple dynamic real-time pictures on multiple display terminals at the same time. The products are mainly used in radio and television engineering, multimedia conference hall, large-screen display engineering, television teaching, command and control center and other fields. All right.

This product adopts a large-scale array processing framework of FPGA, full hardware card design. It integrates ultra-high bandwidth video signal acquisition, real-time high-resolution digital image processing, two-dimensional high-order digital filtering and other high-end image processing technologies. It has powerful processing capacity, and can fundamentally guarantee all input video into. Full real-time processing, no delay, no frame loss. It can support various input modes of analog or digital signal sources, such as computer signal (VGA/RGB), high-definition component signal (YPBPR), composite video CVBS, high-definition digital signal (DVI/HDMI), HD-SDI/3G-SDI, optical fiber, etc. It can automatically detect the input state of signal, and input image resolution can support almost all of the current. Common display resolution, digital video can support 1080P high-definition signal. Support DVI / HDMI output mode, output resolution support all common realistic resolution. Output picture not only has excellent image quality, but also adds many new functions, such as dynamically adjusting window size, roaming window, overlapping window, etc. Each input of splicer can be adjusted and positioned at any position on the screen. The display mode is almost unlimited and supports real-time and dynamic window movement. And adjust the window size.

3、RS-232Communication Port and Connection Method

This series of products provide two serial ports: RS-232 input port and RS-232 output port (Fig. 1.6-1), input port and computer connection, output port connected with other communication equipment through serial port and computer. If users want to use a computer or central control equipment to control multiple serial devices, it will take up too many serial ports, and use our equipment can achieve multiple device cascade. Signals are input from RS-232 input port and output from RS-232 output port to other devices, thus eliminating multiple serial ports of users. The connection method can be referred to in figs. A and B.

II. PRODUCT CHARACTERISTICS AND TECHNOLOGICAL PARAMETERS

1. Product Characteristics

Pure Hardware FPGA Architecture--Using pure hardware FPGA image processing architecture, using excellent image processing algorithm, fast start-up speed, high stability, no operating system, to avoid crash, blue screen, hardware conflict, virus interference and so on.

The puzzle of the question.

Design of Hot Plug-in Board CardFlexible card hot plug-in design is adopted. All input signals are designed as input cards, all output signals are designed as output cards, power supply part is designed as power supply board, control part is designed as control board, and switching system is designed as backplane. At the same time, it supports hot-swap and does not need to restart the device. It can expand the input and output scale of the splicer on-line.

6.25G High Speed Bus Switching TechnologyA 6.25 Gbps/s rate switching chip is used to ensure the uncompressed point-to-point input and output of the highest 1080p signal, and the switching speed is at NS level.

Optional Size Configuration - - -Rich chassis size configuration, can choose 3U chassis, maximum support 16 input, 16 signal output, optional 6U chassis size, maximum support 36 input, 36 output scale, optional 12U chassis, maximum support 72 input, 72 output scale.

Multi-picture roaming overlay displayThrough the software control of the upper computer, the window can be opened arbitrarily, the window size can be adjusted in real time, the moving window can be displayed by splicing the windows across the screen, and multiple windows and multiple layers can be displayed in a single screen.

Double screen and double line functionThe device has the function of doubling and multiplying the input signal frequency. It can process the doubling and multiplying line of the input signal with low resolution and low field frequency. It can process and output the same resolution signal in a unified way, which greatly improves the overall quality of the picture.

Seamless real-time switchingThe signal switching process is free from black field disturbance and achieves seamless real-time signal switching.
