Abstract

A recording and reproducing device (1) in which, when the power is turned off, the state of the power can be controlled to be in either one of a first power-off state and a second power-off state in which the recording and reproduction device (1) can be started faster than in the first power-off state. The recording and reproducing device (1) has a “first standby mode” during which the power state of the device is controlled to the first power-off state when the device receives a power-off instruction, and a “second standby mode” during which the power state of the device is controlled to the second power-off state when the device receives a power-off instruction. A power controller (30) makes, according to a setting time zone, the second standby mode active only for a predetermined time zone including the setting time zone.

Claims

1. A recording and reproducing device capable of recording and/or reproducing video and/or audio data, comprising:

(a) a signal processing circuit for processing video and/or audio data;

a drive unit for recording the processed data to a recording medium; and

a power controller for controlling supply of power to the signal processing circuit and drive unit, wherein

(b) during power-off state of the recording and reproducing device, the power state of the recording and reproducing device can be controlled to be in either one of a first power-off state and a second power-off state, the second power-off state capable of making the recording and reproducing device start at a higher speed than that of the first power-off state when receiving a power-on instruction,

(c) the recording and reproducing device has a first standby mode for controlling the power state to the first power-off state when receiving a power-off instruction, and a second standby mode for controlling the power state to the second power-off state when receiving a power-off instruction, and

(d) the power controller makes the second stand-by mode active according to a setting time zone for a predetermined time zone including the setting time zone.

2. The recording and reproducing device of claim 1, wherein the supply of power to the signal processing circuit and drive unit is stopped in the first standby mode, and the supply of power to the drive unit is stopped and the power is supplied to the signal processing circuit in the second stand-by mode.

3. The recording and reproducing device of claim 1, wherein the setting time zone can be set to make the second stand-by mode active or inactive all the time.

4. The recording and reproducing device of claim 1, wherein the setting time zone is set on the basis of results of learning times of power-on and power-off operations by the user.

5. The recording and reproducing device of claim 1, wherein the power controller transfers to the first standby mode when a predetermined time elapses in the second standby mode after the second standby mode starts.

6. The recording and reproducing device of claim 5, wherein the predetermined time can be set by the user.

7. The recording and reproducing device of claim 1, wherein the signal processing circuit receives electronic program guide information, and the setting time zone is set according to time zone having no broadcast obtained from the received electronic program guide information.

8. The recording and reproducing device of claim 1, further comprising a processing unit for creating a setting screen through which the user enters setting information on the setting time zone,

wherein the setting screen displays time information entered by the user as the setting information, and power consumption and/or electricity charge according to the entered time information.
