Abstract
The disclosure discloses a back-end circuit for processing an analog video signal and direct current power, a front-end circuit for processing an analog video signal and direct current power and a Power Over Coaxia (POC) circuit for an analog video signal. Each of the back-end processing circuit and the front-end processing circuit includes an analog video signal passing circuit configured to block the direct current power and let the analog video signal pass and a direct current power passing circuit configured to block the analog video signal and let the direct current power pass, so that the analog video signal may be isolated from the direct current power and the analog video signal may be superimposed to the direct current power without mutual influence and exclusion to realize a function of superimposing the direct current power on an analog high-definition video cable.
