TRANSMITTING DEVICE, METHOD FOR TRANSMITTING DEVICE POWER SUPPLY SWITCHING, RECEIVING DEVICE AND METHOD FOR SUPPLY OF POWER TO SUCH RECEIVING DEVICE

摘要

FIELD: electrical engineering.SUBSTANCE: transmitting device contains a signal transmission module intended for transmission of a video signal into the receiving device via a cable in the form of differential signals through multiple channels. The device also contains an information transmission module intended for transmission of request information requesting supply of power to the receiving device via the cable. Additionally, the device contains a module for power supply switching intended for supply of power transmitted from the receiving device via the cable into its internal circuits alongside with transmission of request information from the information transmission module. The information transmission module enters request information in the period of damping of the reverse course of the video signal transmitted from the signal transmission module and transmits request information into the receiving device.EFFECT: transmitting device power supply circuit simplification.16 cl, 21 dwg
