Video device for vehicle, has connecting line which connects video interface with power supply unit, with supply voltage of video interface to be transferred to power supply unit

摘要

The video device (203) has an indicating unit (222) which displays or records the image information. A control unit determines the energy consumption of the video device, and outputs information relating to the energy requirements for the transmission of the video interface. A power supply unit (226) generates an operating voltage for operating the video device, from the supply voltage (219). A connecting line (228) connects the video interface with the supply unit with the supply voltage of video interface (220) to be transferred to the supply unit. Independent claims are included for the following: (1) control device; (2) video system; and (3) method for operating video device.
