From The Outlook of Technology, The Choice Of Control Room LED Processor

Small pitches are becoming more and more popular, but the small-pitch LED display can not achieve the ideal display effect without the auxiliary role of the video processor. Unlike outdoor LED card, small-pitch LEDs are subject to many restrictions in terms of image display.

  • The brightness of the indoor environment is different, so the brightness of the LED screen cannot be as high as outdoors. This requires the video processor to have better image quality improvement capabilities, especially more advanced image scaling processing algorithms, so as to ensure that high-definition video images can maintain the detail clarity and grayscale of the image after scaling processing. level. Secondly, there must be rich image adjustment options and adjustment effects, especially the adjustment of image brightness, contrast, and low-gray processing, so as to ensure that a soft, clear and layered picture is output under the screen indoor light environment.
  • The indoor display is limited by the area of ​​the venue. It is required to display the highest possible clear video and images within the limited display area. This requires the video processor to have higher resolution image output capabilities, higher resolution, and more video image input capabilities.
    The traditional indoor large screen applications are large screen displays for monitoring, command and control occasions. These applications require large screens with high definition, multiple input signals, more real-time video window screens, and flexible and fast control of these screens. And management.

LED video processor is the witness and key equipment of the birth, growth and maturity of LED full color display. The quality of LED video processor directly affects the display effect of LED display. So from the user’s perspective, how to choose a suitable processor?

Taking the control room application as an example, the control room is one of the most demanding environments for video wall processors. In many cases, the real-time and integrity of the signal will affect the accuracy of decision making. Therefore, in addition to considering the stability of the product in the selection process, the user also needs to conduct a comprehensive review of the real-time processing capabilities of multiple input signal sources, whether they are easy to use, and the specific application environment.

When selecting a processor, the first consideration is to be able to reproduce the signal source in the system. This is a basic requirement of every video system used for decision-making, because distortion of image resolution conversion may cause content to be misinterpreted. Second, unstable video performance, such as dropped frames or freeze frames, will distract users and hinder correct content analysis; again, control rooms will often useful multiple signal source types, and the correct processor must be compatible These signal sources; Finally, the flexibility of configuration must also be considered. Because the number of inputs, input types, and screen arrangement of the video wall in each project are different, the video wall processor needs to be flexible to configure to meet these specific applications. Demand.

In addition, in the design of an excellent control room solution, the specific application environment and how to use it need to be considered. For example, the needs of utility management centers are not the same as those of military agencies. Understanding the type of information that needs to be displayed and how to present it is the first step in choosing a video wall processor.

Control room usually involves and uses multiple signal source types. Compatibility with control room-specific signal types and the ability to display a large number of source windows ensures 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 becoming a requirement.

An excellent solution must consider both the requirements for implementation and the new requirements that may arise in the future, such as the convenience of operation, display effects, and viewing comfort involved in signal access, processing, scheduling, and display. System maintenance and expansion must be taken into account when selecting the video wall processor.
