Stromversorgungsvorrichtung und Steuerverfahren

摘要

The power supply includes a first voltage regulator 22 for supplying a controller 25; a second voltage regulator 23 for supplying power to portions of the video recorder which operate only in a operation mode of the video recorder 26, 27, 28; and a third voltage regulator 24 for supplying power to portions 29, 30 which perform a program reservation function and a timer function. The controller, in a power on mode, outputs a signal for turning on the second and third voltage regulators. In a power off or standby mode, the controller ascertains whether there is a reserved program or not so that if not, a signal for turning off the second and third voltage regulators is output, but if so, a signal for periodically turning on/off the third voltage regulator portion is output. Thus the tuner portion may be separately powered during the standby mode, which is particularly relevant to VPS-equipped video recorders. <IMAGE>
