large-screen self-service terminal

large-screen self-service terminal is widely used in communication, power, and military command agencies. It plays an important role in providing shared information, decision support, situation display, BSV LCD splicing and split screen display. The large-screen self-service terminal is a process of collecting various information and receiving. It integrates various technical problems in the operation and control of sound and light personnel. It also involves the coordination of relevant management departments. It is also closely related to the overall structure of the display hall. It is necessary to pay attention to the multimedia interactive system, give priority to demand, consider as a whole, and adopt integrated technology to achieve the expected results.

Design Large-screen self-service terminal must first put forward requirements. The following are the general main functions and requirements. Receiving information: The system should not only be able to receive VGA, RGB, network computer information, but also be able to receive broadband voice and video signals, and perform appropriate information conversion as needed.

2. Information display: The system can publish shared information in the form of multimedia, and display situation, text, table and video image information in different ways according to the divided area. It requires clear scene display, high resolution, clear and stable text and image display. BSV LCD splicing technology realizes the function of system window roaming and picture in picture.

3. Preview, camera and switching: In order to ensure the accuracy and quality of the projection display information, the system has a preview function of image pre-review. Cameras are installed in the exhibition hall to extract video images of the work of the management and control agencies. The system should have switching display function to meet the needs of multi-channel information display.

4. Conference call: The system can use monitoring, preview, switching, communication and terminal control equipment to maintain video contact with relevant parties, and can hold conference calls at any time.

5. Control mode: The system enables leaders, business personnel and security personnel to open and close large screens, open windows, select information sources, project display, adjust sound and light, etc. through centralized control, mobile control, authorization control, etc. Operation.

6. Optimized design according to standards: The system equipment configuration is complex, there are many cable signals, and the installation process and environmental conditions are high. Engineering wiring and equipment installation are carried out in accordance with line standardization, electromagnetic compatibility standards and large screen installation requirements to ensure long-term stable operation of the system. For any input in the red, green, and blue channels, we have a desired output value, so there will be a corresponding relationship. By observing these three aspects, you know what kind of harvest you need. What are the performance improvements of the six-color wheel compared to the three-color wheel? First, let's look at the middle color. Except for the triangle where RGB is within the gamut, any intermediate portion of an intermediate color is actually directly related to the expression of the intermediate color. Extreme color techniques can increase the brightness and saturation of the entire halftone because we use different color segments that complement each other. 30
