4K videowall splicing processor solution

Background requirements:

CV, Y/C, YUV, VGA, DVI, HDMI, SDI, HDBaseT these interfaces were used as matrix interfaces in the past, and as times are developing rapidly. Now these interfaces are all used in a hybrid splicing matrix. , is applied in various industry scenarios.
Like the large-screen multi-screen or splicing screens used in the movie and TV programs of the government and enterprise theme pavilions today, and the special-shaped screens in the advertising industry, all of these must be rebuilt on the basis of the video splicing processor to achieve the desired effect. .

Traditional LCD splicing screens cannot be realized with built-in splicing boards. Any opening, roaming, superimposing, and full 4K splicing (4K resolution for each single screen) still need to be completed by an external splicing processor or splicing module.
The current LED module screen is to splice multiple small modules together. The LED module screen is also recognized as the one with good splicing effect and low heat generation, but it is difficult to achieve command because of its own splicing function. The large screen in the center and the diversified display still need the blessing of the hybrid matrix.

 

Digital rear projection DLP is currently widely used in rear projection display and wall projection display functions. Previous contacts have used splicing processors with large screens to achieve high-definition rear projection and interactive display. This shows the current splicing processor (hybrid matrix) have a big market .

 

Videowall matrix family

It can be widely used in radio and television projects, multimedia conference halls, large-screen display projects, television teaching, intelligent traffic management centers, command control centers and other places.

The above-mentioned functions require the support of a hybrid matrix or a splicing processor to achieve the effect. Choosing a suitable hybrid matrix has become the top priority. The splicing processor produced by our company is compatible with the mainstream screen type in the market: LED technology LCD technology DLP technology, multi-compatibility, unique technology, flexible control, convenient interaction.
 
Features:


1. Flexible interface
  At present, we have supported the mainstream interfaces, and the optical fiber interface (poe onboard power supply) that can achieve ultra-long-distance transmission is partially supported by common video interfaces such as CV, Y/C, YUV, VGA, Component, DVI, HDMI, SDI, HDBaseT crossover signals Audio de-embedding allows the audio and video to be separated or combined to splice the output signal.
 
2. Safe hardware system
Using FPGA pure hardware technology architecture, no hard disk, no maintenance, no operating system, avoiding system crashes, blue screens and computer virus intrusion problems; fully modular, users can customize the corresponding boards according to their own needs; channels are exclusive, The number of connected signals will not affect the performance of the system; input and output cards, etc. support hot-swappable, which can be replaced and upgraded without power.

3.flexible control
  The control adopts b/s architecture to realize full platform control. Andiro ios mac windows linux adopts optimized technology to make the platform equipment run smoothly. It supports RS232/485 serial port control. The preset video splicing scheme can be called by one button or controlled by operation.
 
4. high-quality signal
  Video signals from 1080P to 2K*4K support transmission. Even in long-distance video transmission, we use unique frame synchronization technology to stabilize the picture to ensure that the pictures of all output ports are completely synchronized, and the picture is smooth and complete without tearing.
 
5. visual operation
  The hybrid splicing matrix supports PC and tablet platforms, and manages all devices in the system through a set of customized exclusive interface, local preview of video signal and splicing layout, real-time control of signal source and large-screen display status, and intuitive touch control.
 
6. functionality, compatibility
Signal preview: You can preview the video signal on the wall in advance to ensure that the customer's display content is foolproof.
Seamless switching: millisecond-level signal retrieval, truly realizing full-signal switching experience without black field, and supporting simultaneous use of switching splicing.
Character overlay: Support source font to modify size, color and position to make information data more intuitive.
Plan management: Personalized plan call, supports splicing processor or local PC plan for flexible and fast one-key call.
Video wall solution: Supports different resolutions, one-click application of preset video wall solutions to display different scene style themes.
 
7. Self-developed technology
  Infinite zoom adopts self-developed multi-phase filtering algorithm to ensure that the image is still clearly displayed on the mosaic wall after zooming. The traditional processor uses bilinear interpolation algorithm, when the original image is compressed, the overall image becomes blurred, and the edges appear blocky and jagged with pixel loss; while the stepless zoom algorithm is used to compress the original image, the image edges are smooth Transition, the whole picture is uniform without distortion, and the text lines are still clear and recognizable.
 
8. Humanized product design
  The product has a humanized display button, the crystal button backlight can adjust the splicing processor in no light situation, and supports USB firmware upgrades to obtain more new functions. The complete authority distribution system can assign sub-function authority to any maintenance personnel.
