Introduction to the concept and features of the splicing processor

[ Huaqiang Security Network News ]

I. Overview

The video splicing controller is a professional video processing and control device. The main function is to divide one video signal into multiple display units, output the divided display unit signals to multiple display terminals, and complete the splicing with multiple display screens. A complete image, the process is completely hardware, no need for computer and startup software, it is very simple.

Note: The display terminal can be a DLP large screen, a PDP large screen, an LED display, a projector, a monitor, an LCD TV, and the like.

Splicing processor

Second, the splicing processor introduction

The splicing controller adopts pure hardware structure design, no operating system, the whole system is completely closed operation, no need for computer and startup software, etc. It is very simple and stable, and the stability is much higher than the "computer + board" mode based on WINDOWS operating system. The traditional controller of embedded system design adopts the most advanced high-speed video processing chip in the world, and applies advanced digital image processing algorithm (de-interlacing algorithm) to process multiple video VGA images in real time, even if the compressed picture is on the projector. It is very suitable for occasions requiring long-term continuous and stable operation. It can be started quickly after 1 second and is maintenance-free.

The splicing controller specializes in splicing controllers for large screens, projections, LCDs, etc. The latest introduction of US-specific ultra-high-speed chips, while supporting non-real-time display of any PC desktop image in TCPIP network, can control multiple real-time video and VGA To UXGA combination display. The TV wall composed of the processor has high resolution, high reliability, natural and smooth dynamic images, clear and beautiful, low cost and rich display special effects. Suitable for high-end areas such as command, video conference, 3D presentation, monitoring, advertising and other UXGA and video mixing applications. Multiple cascades can form a TV wall of any size. Direct connection monitoring DVR VGA interface, TV conference TV wall terminal, WEB video monitoring workstation terminal. It is specifically designed for demanding real-time ultra-high resolution applications.

Widely used in: monitoring, command, dispatch system, public security, fire, military, meteorological, railway, aviation and other monitoring systems, video conferencing, query systems.

Third, the characteristics

Split one video/VGA signal into a combination of 1x4 and 2x2 effects

·Two different display effects can be selected by remote control/software control;

·Automatic adjustment of brightness, contrast, chroma, smoothness of image parameters;

· The output is displayed in the display format XGA or SXGA, directly driving the flat panel display device or projector;

· Three different edge processing techniques to achieve the best stitching effect according to different situations;

·The processor has built-in digital multi-screen color balance. After the digital three-primary color adjustment circuit, the three primary colors of each projection unit are effectively suppressed, so that the red, green and blue primary colors are all consistent, so that the color of each splicing unit can be consistent. Sex, the wall has no obvious color difference. ;

Reliability pure hardware splicing processor is the only high-speed processor that can display full-screen dynamic real-time display VGA to UXGA progressive ultra-high resolution pure hardware image. It is ideal for applications requiring long-term continuous stable operation. , maintenance free.

The maximum expandability can be simultaneously connected to display 24 channels of VGA to UXGA and 96 channels of video, and arbitrarily select one of them to zoom to full screen.

The simple series video splitter processing process is completely hardwareized, and does not require operations such as a computer and boot software. It is very simple, and can be connected to the signal line and connected to the power supply to work.

Supports high-definition television (HDTV) input and output with modular design, according to different needs, increase or decrease different functional modules. Meet your requirements with the best performance and price ratio. It can be configured to support specifications such as 2 division to 48 division according to the actual needs of users.

A variety of display and window mode series 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 preset a variety of modes, users can also Define the pre-stored mode.

3L Electric Wallpaper Stripper

The 2200W 3L Electric Steam Wallpaper strippers is the most productive, safest and easiest to use steam wallpaper stripper.

The Wallpaper Stripper force steam through the layers of paper, helping to not only remove the paper but also glue residue from walls.The Wallpaper Steam Stripper is particularly effective on stubborn papers with paint on, or wood chip paper.

The Electric Wallpaper Remover Stripper is much easier, compared to soak and scrap off the wallpaper manually, it only uses water which is heated.

The 3L Electric Wallpaper Stripper With overload protector which allows the excess steam to be released, to protect your safety.

Simply fill with hot or cold tap water and connect to the power supply. The Electric Wallpaper Stripper will steam-up in 10 minutes and continue to run for around 45 minutes, before switching off automatically when a low water level is reached.

The user then simply disconnects the Wallpaper Stripper from the power supply, waits 2 minutes to allow the steamer to cool, and then refills. This eliminates the need for the user to remember to constantly check the water level. Even if it is left connected to the power supply with a low water level it will safely switch on and off as the heating element cools down and heats up.
