Abstract

A video/audio processing device, such as a DVD recorder, includes a controller for controlling a state of power-on/off. The controller has a first standby mode and a second standby mode having power consumption larger than that of the first standby mode in a power-off state of the video/audio processing device. The first standby mode is a mode for maintaining a power of the video/audio processing device in the “off” state. The second standby mode is a mode for maintaining the power of the video/audio processing device in an apparent “off” state. The controller switches between the first standby mode and the second standby mode in conjunction with a state of power-on/off of external equipment such as television.

Claims (7)

1. A video/audio processing device for processing video and/or audio signals, comprising:

a controller configured to control a state of power-on/off of the video/audio processing device, the controller having a first standby mode, and a second standby mode that has power consumption larger than that of the first standby mode, in a power-off state of the video/audio processing device,

wherein the controller:

1) automatically updates a power-on time and a power-off time by learning a user's operation,

2) when power off operation is provided by the user to the video/audio processing device, determines whether the time at which power off operation is provided is in a range from the power on time to the learned power off time, based on the learned power on time and the learned power off time, and

3) switches a mode to the second standby mode when the time at which power off operation is provided is in the range, or switches a mode to the first standby mode when the time at which power off operation is provided is not in the range.

2. The video/audio processing device according to claim 1 , wherein the second standby mode is a mode which enables faster start of the video/audio processing device than the first standby mode when power-on operation is provided by a user.
