前言随着视频监控技术的不断发展,模拟视频监控系统已经逐步被数字视频监控系统所替代,标清视频也逐步被高清视频所替代,视频数字化、高清化是未来视频监控的发展方向。高清数字视频分为IP网络高清视频和数字非压缩视频两种,IP网络高清视频有着组网灵活、占用存储空间小、成本低的优势。而高清非压缩视频可以提供高分辨率、低延时、运动过程更清晰的图像,视频效果远远超过压缩过的IP网络高清视频。目前大部分监控系统采用IP方案,但相对于IP网络高清,HD-SDI高清系统具有以下优势: Preface With the continuous development of video surveillance technology, analog video surveillance system has been gradually replaced by digital video surveillance system, standard definition video has been replaced by high-definition video, video digitization, HD is the future direction of video surveillance. HD digital video is divided into IP network HD video and digital uncompressed video two, IP network HD video with flexible networking, small storage space, low cost advantages. The high-definition uncompressed video can provide high-resolution, low latency, clearer image of the movement process, the video effect far exceeds the compressed IP network HD video. At present, most monitoring systems use IP solutions, but relative to the IP network HD, HD-SDI HD system has the following advantages:
