High-definition video signal transmission method

At present, high-definition video signals include analog, digital, and network transmission. The first two methods are used to transmit lossless, uncompressed analog and digital HD signals.

Analog HD signal transmission

YPbPr component transmission is generally used. All high-definition video signals need three coaxial cables to transmit at the same time. The cable usage is very large. Although the transmission distance of the component can be extended by a third-party device, since the analog signal is transmitted, the signal is damaged after being transmitted over a long distance. Therefore, YPbPr component transmission is not suitable for HD monitoring.

Digital HD signal transmission

Generally use DVI, HDMI or HD-SDI transmission, which DVI or HDMI transmission distance is only a few meters, not suitable for monitoring transmission, HD-SDI can transmit about 100 meters, but the demand for coaxial cable is high, cable The price is also very expensive, so it can only be used for large-scale applications in the system.

Network HD signal transmission

As the name suggests, it is the transmission of high-definition video signals over the network, often using a star-architected Ethernet network to deliver high-definition network video signals. The transmission distance varies according to the selected line, from 100 meters to several tens of kilometers. Compared with the previous analog and digital methods, the transmission cost is relatively low, and the performance is stable. It is currently the most widely used in high-definition monitoring systems. A cost-effective transmission method.
