    Large-screen display systems have become more and more known in recent years, and their application fields have spread across many industries. For many complex signal receiving and processing, it is far from enough to rely on the large-screen display system's calculation and processing capabilities. Therefore, when we are often able to see high-definition video conferences or large-screen displays of live broadcasts, a lot of credit goes to the video capture card. So what role does the video capture card play in the large screen splicing system?
    Large screen splicing is currently visible everywhere in the country. The advanced technology of large screen splicing has made it widely used. The functions of the entire large screen splicing include network roaming and image overlay. It forms an arbitrary splicing function on a large screen. Multiple signal input displays Under the normal operation of the LCD splicing screen, it is convenient to operate, and a central controller is added to control the splicing wall, matrix, and conference terminal. The following US Miffett introduces the use of video capture cards on LCD splicing screens and what role they play in LCD splicing screens based on years of experience.
    HD VGA video capture card belongs to a type of video capture card. It is mainly a video capture card that captures VGA signals. When it comes to HD VGA video capture card, it is related to the display system of the LCD splicing screen. HD is important in display equipment. In order to meet the requirements of multiple VGA display devices 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 display output. On the large 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 the large screen splicer. This function requires a VGA video capture card. For some graphics or video playback workstations, the requirements for high-definition VGA video capture cards will be very high, such as 1080P, 720P, and so on. 视频 采集卡,不仅能采集到高分辨率,还要求高速度,高帧数。 That is, a VGA video capture card is required , which can not only capture high resolution, but also high speed and high frame number.
    视频 采集卡,例如液晶拼接屏显示系统如果在进行直播视频会议的时候,利用VGA 视频 采集卡或采集盒做屏幕直播,画面清晰很多,而利用VGA 视频 采集卡也可以多媒体教学和远程教学。 Large screen display systems are inseparable from VGA video capture cards. For example, the LCD splicing screen display system uses a VGA video capture card or a capture box for live screen broadcasts during live video conferences . The picture is much clearer, and the use of VGA video capture cards also Can multimedia teaching and distance learning. 视频 采集卡它可以处理特殊的视频格式,用VGA 视频 采集卡或采集盒配合流媒体编码软件,实时采集、编码成流媒体格式,放到流媒体服务器上供大家点播。 The VGA video capture card can handle special video formats. Use a VGA video 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. 视频 采集卡或采集盒将其采集成未压缩文件AVI形式,进行编辑。 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 video capture card or capture box to capture it into an uncompressed AVI format for editing. In order to achieve the high-definition display effect of the large LCD splicing screen, to achieve the best resolution.
    视频 采集卡能够同任何拼接大屏幕卡配合保用,配合VGA信号 视频 采集卡以及其它多种多屏图形处理显示产品,可以用于各种多屏拼接应用。 VGA high-definition video capture card can be used with any splicing large-screen card . It can be used with various multi-screen splicing applications with VGA signal video capture card and other multi-screen graphics display products. So as to achieve a good video effect and achieve high-definition pictures. 视频 采集卡已在液晶拼接大屏幕上广泛使用,相信在未来的时间,它一定会很好的配合液晶拼接大屏幕打造出完美的显示设备。 VGA high-definition video capture card has been widely used on the large LCD splicing screen, I believe that in the future, it will definitely work well with the large LCD splicing screen to create a perfect display device.
