POC function of he-20

Post by Erik » Wed Dec 25, 2019 7:45 am

He-20 has POC function, which can supply power to RX from TX and TX from Rx. POC (power over coaxial) is a technology based on coaxial video, coaxial control and power superposition. In coaxial cable transmission, high-definition video signal, coaxial signal and power supply are transmitted, that is, high-definition video, coaxial and other signals are combined with power supply to transmit on a coaxial line.

POC adopts single-wire transmission mode, only using two-core coaxial cable structure is more convenient and simple, then in practical application, we need to pay attention to what convenience, usually the transmitter is not needed to use power supply, when image transmission is unstable or unable to achieve normal transmission, power supply is insufficient, you can choose to only TX or RX power supply, if single-end power supply can not solve the problem, it is suggested that TX and RX can supply power.
