什么是HDCVI2012年11月,大华技术股份有限公司发布了具有自主知识产权的同轴高清传输接口技术HDCVI。HDCVI技术是一种基于已有SYV75-3或SYV75-5同轴电缆的高清视频传输方法,能够在低成本和较低质量的同轴电缆上实现超长距离高清视频信号的可靠传输。相比较HD-SDI子系统在实际应用中对传输介质的高要求,HDCVI可以适应长距离、低成本的传输介质以及复杂的部署场合。HDCVI在调制方面采用基带调制与正交调幅调
What is HDCVI In November 2012, Dahua Technologies Co., Ltd. released HDCVI, a coaxial HD transmission interface technology with independent intellectual property rights. HDCVI technology is a high-definition video transmission method based on the existing SYV75-3 or SYV75-5 coaxial cable, which enables the reliable transmission of ultra-long distance high-definition video signals on low-cost and low-quality coaxial cables. Compared with HD-SDI subsystem in the practical application of the high transmission medium requirements, HDCVI can adapt to long-distance, low-cost transmission media and complex deployment.
