防汛工作具有信息量大、实时性要求高等特点,随着防汛工作的要求越来越高,数字视频技术在防汛中的应用也是先进可行的,为此我局组织对该项技术的应用进行了调研,并结合河南局的实际进行了研究,并进行了系统建设以服务于防汛。1 数字视频的相关标准及其技术1.1 技术基础数字视频系统的优点正好克服了模拟视频系统的局限性:首先,数字化视频可以在计算机网络(局域网或广域网)上传输图像数据,基本上不受距离限制,信号不易受干扰,可大幅度提高图像品质和稳定性;其次,数字视频可利用计算机网络联网,网络带宽可复用,无须重复布线;另外,数字化存储成为可能,
Flood control work with a large amount of information, real-time requirements of higher characteristics, with the flood control requirements are getting higher and higher, digital video technology in flood control is also advanced and feasible, for which I organized the application of the technology Research, combined with the actual Henan Bureau conducted a study and conducted a system to serve flood control. 1 Digital Video Standards and Technologies 1.1 Technical Basics The advantages of digital video systems overcome the limitations of analog video systems. First, digital video can be transmitted over computer networks (LANs or WANs) with virtually unaffected distance Limit, the signal is not subject to interference, can greatly improve the image quality and stability; Second, the digital video network can be used computer networking, network bandwidth can be reused, without duplication of wiring; In addition, digital storage is possible,
