1. Overview
The CVBS video masking controller developed by Ning Pengda Technology is a video signal processing and control product. Its main function is to process the input CVBS video signal so that the corresponding image of the output CVBS video signal can only display the part within the specified area, while the part outside the area remains at a fixed grayscale. Visually, this is equivalent to certain areas of the video image being "masked." In general applications, area masking primarily serves to protect privacy, shield interference, highlight displays, and more. With the increasing variety of video products and the broadening of application fields, for many video products, processing the original video image with area masking can enhance product functionality and improve the user experience. Using this product to achieve masking does not involve modifying the video signal source, video display hardware or software, or editing video content. Therefore, this product is not only suitable for the development of new products but can also be used for upgrading existing equipment. This product is meticulously crafted using the latest semiconductor devices combined with modern electronic assembly processes, offering advantages such as stable performance, compact size, and easy installation. The product achieves its functionality by directly processing analog video signals, ensuring that the video output signal is real-time and synchronized with the video input signal. Additionally, it employs special technology, giving it outstanding advantages over similar products on the market, including no damage to the input signal, no delay in output response, no jitter in the masked area, high signal processing precision, and the ability to achieve semi-transparent and automatic reverse effects. This product can mask any area of the video image, and the shape, position, grayscale, display mode, adjustment range, and other supporting functions of the masked area can be customized according to customer requirements. The product is available in three forms for customers to choose from: component type, board type, and device type. All products are compatible with PAL and NTSC systems, suitable for various display ratios. Video interfaces, control interfaces, power interfaces, and related parameters can be customized based on the customer's specified video signal source, video display screen, actual application scenarios, and functional requirements.
