Control room LED processor selection from the perspective of technology

The small pitch is getting more and more popular, but the small-pitch LED display is indispensable for the auxiliary effect of the video processor in order to achieve the desired display effect. Unlike outdoor LED large screens, small pitch LEDs are subject to many constraints in image display.

First, the brightness of the indoor environment is different, so the brightness of the LED screen is not as high as that of the outdoor. This requires the video processor to have better image quality enhancement, especially the need for more advanced image scaling processing algorithms to ensure that the high-definition video image can maintain the image's detail sharpness and gray level after being scaled. Secondly, there must be a wealth of image adjustment options and adjustment effects, especially image brightness, contrast adjustment and low gray processing, thus ensuring a soft, clear and well-defined output in the light environment of the screen room.

Second, the indoor display is limited by the size of the site, requiring to display as high a clear video and image as possible within a defined display area. This requires the video processor to have higher resolution image output capabilities, higher resolution and more video image input capabilities.

Third, the traditional application of indoor large screens is a large-screen display for monitoring, command and control applications. These applications require high-definition high-definition, multiple input signals, more real-time video window screens, and flexible and fast screens. Control and management.

LED video processor is the witness, and key equipment for the birth, growth and maturity of LED full-color display. The advantages and disadvantages of LED video processor directly affect the display effect of LED display. So how do you choose a suitable processor from the user?

Taking the control room application as an example, the control room is one of the most demanding environments for the splicing wall processor. In many cases, the real-time and integrity of the signal will affect the accuracy of the decision-making judgment. Therefore, in addition to considering the stability of the product, the user needs to comprehensively investigate the real-time processing capability of multiple input signal sources, ease of use, and specific application environment.

When making a processor selection, the first consideration is to be able to reproduce the signal source within the system. This is a basic requirement for each video system used for decision making, because image resolution distortion may cause the content to be misinterpreted. Second, unstable video performance, such as dropped frames or freeze frames, distracts the user's attention and hinders proper content analysis; again, the control room typically uses multiple source types, and the correct processor must be compatible. These sources; finally, consider the flexibility of the configuration. Since the number of inputs, the type of input, and the screen layout of the videowall vary from project to project, the videowall processor needs to be flexible enough to meet these specific applications. Demand.

In addition, in a good control room solution design, you need to consider the specific application environment and how to use it. For example, the needs of the utility management center are different from those of military institutions. Knowing the type of information you need to display and how to present it is the first step in choosing a videowall processor.

Control rooms typically involve and use a variety of signal source types, compatibility with control room-specific signal types, and the ability to display a large number of source windows to ensure that control room staff can see important information that can help them more efficiently jobs. In addition, as many organizations choose to display HDMI satellite broadcast signals or Blu-ray content, compliance with the HDCP standard is increasingly becoming a requirement.

An excellent solution, both to consider the requirements of implementation, but also to consider new requirements that may arise in the future, such as signal access, processing, scheduling, operation convenience, display effect, viewing comfort involved in the display process. System maintenance, expansion, etc. are all taken into account when selecting a splicing wall processor.
