数字视频总线技术是以网络形式传输视频信号实现多传感器视频资源共享的新方法。它的基本原理是将多路原始视频信号转换成数字信号,利用网络传输至各使用终端。其相对模拟视频信号传输增大了视频信号的传输距离,同时减少了模拟视频传输存在的信号干扰。本文对数字视频总线技术的原理和关键技术发展进行了介绍,为数字视频总线技术的实现提供了技术途径。
Digital video bus technology is a new method of video signal transmission in the form of network to achieve multi-sensor video resource sharing. Its basic principle is to convert multiple original video signals into digital signals and transmit them to each use terminal through the network. Its relative analog video signal transmission increases the transmission distance of the video signal while reducing the signal interference present in the analog video transmission. This article introduces the principle of digital video bus technology and the development of key technologies, and provides a technical way for the realization of digital video bus technology.
