The effect of large screen splicing technology combined with high-definition VGA capture card
With the continuous development of technology, various video applications have also been increasing. For example, large-screen splicing has been seen everywhere in China. The advanced technology of large-screen splicing makes it widely used. The entire large-screen splicing function includes network roaming and image overlay. It forms an arbitrary splicing function on a large screen and multiple signal inputs. Display, and under the normal operation of the LCD splicing screen, it is easy to operate, and a central controller is added to control the splicing wall, matrix, and conference terminal. The following introduces the application of VGA capture card on the LCD splicing screen, and what role it plays in the LCD splicing screen.
HD VGA capture card is one of the video capture cards. It is mainly a video capture card that captures VGA signals. When it comes to HD VGA capture cards, it is related to the display system of the LCD splicing screen. HD is an important one in display equipment. Features, in order to meet the needs of multiple VGA display devices can be displayed on a large screen, the computing power of the large screen splicer alone cannot be satisfied. This requires the large screen splicer to receive multiple signals and integrate the display output to the large screen. On the screen, VGA and DVI signals are two of them. In simple terms, the information displayed by another workstation is displayed on the large screen by a large screen splicer. This function requires a VGA capture card. For some graphics or For workstations playing video, high-definition VGA capture cards are required, such as 1080P, 720P, and so on. That is, a VGA capture card is required, which can not only capture high resolution, but also high speed and high frame number.
Large screen display systems are inseparable from VGA capture cards. For example, the LCD splicing screen display system uses VGA capture cards or capture boxes for live screen broadcasts during live video conferences. The picture is much clearer, and VGA capture cards can also be used for multimedia teaching. And distance learning. The VGA capture card can handle special video formats. Use a VGA capture card or capture box with streaming media encoding software to capture and encode into a streaming media format in real time and put it on the streaming media server for everyone to order. For some video files, the file format is customized by the development company, and other company software cannot directly process it. You can use a capture card or capture box with streaming media encoding software to encode into a small volume streaming media format. Use a VGA capture card or capture box to capture it as an uncompressed file in AVI format for editing. In order to achieve the high-definition display effect of the large LCD splicing screen, to achieve the best resolution.
The VGA high-definition capture card can be used with any large-screen splicing card. It can be used with a variety of multi-screen splicing applications with VGA signal capture cards and other multi-screen graphics processing display products. So as to achieve a good video effect and achieve high-definition pictures. VGA high-definition capture card has been widely used on large LCD splicing screen. I believe that in the future, it will definitely cooperate with the large LCD splicing screen to create a perfect display device.
