With the development of the information society, LED displays have been widely used in airports, ports, restaurants, hospitals, etc., and LED video processors play an indispensable role in their applications, and thus have also received constant attention. Innovation and development.
So, what does a video processor mean? Read on to discover what a video processor system is and what its characteristics are.
Of course, here at iSEMC we have solutions in all areas, we bring plans to your business and how it can benefit your business.
What is video wall processor?
The video processor is a newly developed video and audio image processor that seamlessly switches multiple video and image inputs.
It can accept various video signals, including VGA computer video, HDMI, DVI, SDI and high-definition video.
It seamlessly combines automatic input format recognition, advanced image resolution conversion technology and synchronous splicing processing technology to meet the needs of high-quality, video and audio synchronization demonstrations.
The video processor adopts advanced backplane switching technology, which distinguishes Based on the traditional bus architecture, it ensures that signal transmission and exchange are carried out through multiple links, avoiding many bottlenecks such as limited bus technology transmission, crashes, slow speed, and impracticality.
The signal processing speed has nothing to do with the number of channels, ensuring With access to large-scale image information, no matter how many signal sources there are, it will not affect the normal use of the system.
Technical features of video wall processor
Screen zoom
The display mode of the LED display is point-to-point, which determines that the LED display can only display images consistent with its own physical resolution. The LED video processor can scale the image, output the picture at any size, and complete the mapping of the entire desktop onto the LED screen.
Signal conversion and switching
Video processing equipment can complete format conversion between numerous signals. Another important function of the video processor is to manage various signals and flexibly and quickly switch between signals when multiple signals are connected.
Improved image quality
Because the pixel pitch of the LED display itself is much larger than that of some other flat panel display media, there are strict requirements for image processing technology, especially image enhancement technology. A high-quality LED video processor can use advanced algorithms to modify signals with poor image quality, and perform a series of processes such as deinterlacing, edge sharpening, motion compensation, etc. to enhance image details and improve picture quality.
Large screen splicing
The pixel pitch of the LED display screen is getting smaller and smaller, and the overall size is getting larger and larger, which makes the physical resolution of the LED screen become very huge. The LED video processor has a splicing function and can drive large-resolution screens, which is a very cost-effective driving method.
Multi-screen processing
In many special scenarios, a display screen needs to display multiple images of the same or different signals. A video processor with multi-image processing function can flexibly meet such display requirements.
Outdoor displays are affected by regional weather, etc., which requires the video processor to have better image quality improvement capabilities and have advanced image scaling processing algorithms to ensure that the video image can maintain the maximum clarity of the image after scaling. and grayscale levels. In addition, the video processor also needs to have rich image adjustment options and adjustment effects to process image brightness, contrast, and grayscale to ensure that the screen outputs a soft and clear picture.
iSEMC has an ultra-large load LED video processor to meet ultra-long on-site configuration requirements and ultra-large screens. Allows display of various types of content such as text, images, and videos. The processor receives the input data and converts it into a signal that can be displayed on the LED display. It has strong stability and diversified functions, providing users with the ultimate visual enjoyment.
Processor system structure
The video wall processor is used for the access, processing, display and control functions of image signals. The signal source is used to provide displayable signals to the system, including computers, playback boxes, cameras, etc. The data of the signal source is distributed, transmitted, switched, etc. link, and finally output to the LCD splicing screen for display.
The video wall processor is the control core of the large-screen display system. It is responsible for sending the image of the signal source to the output large screen according to user requirements, and effectively manages the entire system through the control server in the system.
Definitions of commonly used terms for controllers:
HDMI: HDMI generally refers to high-definition video interface, which is currently used in set-top boxes, TVs, laptops, game consoles, integrated amplifiers, digital audio and other equipment. HDMI is a digital video and audio interface technology that can transmit audio and image signals simultaneously
4K: Support 4K input, achieve single-port maximum resolution signal acquisition of 3840*2160@60Hz, and perform uncompressed processing
8K: 8K LED display means that the resolution of the entire display can reach 7680*4320@60Hz. This is an ultra-high-definition resolution that enables larger-resolution images to be put on the wall and enables ultra-high-resolution point-to-point display. plan
2x3:2×3 splicing screen refers to splicing together 6 LCD screens in 2 rows and 3 columns.
3x3:3×3 splicing screen refers to splicing together 9 LCD screens in 3 rows and 3 columns.
4x4:4×4 splicing screen refers to splicing together 16 LCD screens in 4 rows and 4 columns.
Final thought
When making processor selection, the first consideration is the ability to accurately reproduce signal sources within a small-pitch LED display system.
This is the most basic requirement for every video system used for decision-making due to image scaling distortion. This may result in the content being misinterpreted.
Secondly, erratic video performance, such as dropped frames or freezing, can distract users and prevent correct content analysis.
Thirdly, control rooms often use multiple signal source types, and choosing the right processor must be compatible.
These signal sources; finally, the flexibility of configuration must also be considered.
Since the number of inputs, input types, and screen arrangement of the LED display are different in each project, the LED display processor needs to be flexibly configured to meet these specific needs application requirements.
