Abstract
When the main power supply is turned off, the power supply of a video display unit is turned off and the audio signal is muted. At the same time, a time counting unit counts time, and before reaching a predetermined time, a display unit is lighted to notify a quick restart period. In the case where the main power supply is turned on during the predetermined time, the power supply of the video display unit is turned on to cancel the audio mute mode. In the case where the main power is not turned on upon lapse of the predetermined time, the power supply of the receiving unit is also turned off.
Claims17
A television receiver comprising:
- a receiving unit configured to receive a television broadcast and output a video signal and an audio signal;
- a video display unit configured to display an image based on the video signal output from the receiving unit;
- a mute unit configured to mute the audio signal output from the receiving unit;
- a power circuit;
- a power switch command unit configured to issue a command for turning on the power circuit to supply the operating power to the video display unit on one hand and turning off the power circuit to suspend the supply of the operating power to the video display unit on the other hand;
- a time counting unit;
- a standby mode display unit;
- and
- a control unit configured to switch on/off the power circuit in response to the power switch command from the power switch command unit, detect the command to turn off the power circuit and drive the mute unit to mute the audio signal before the power circuit turns off, cancel the mute mode of the audio signal by detecting the command to turn on the power circuit, detect the command to turn off the power circuit to start the time counting operation of the time counting unit, and display the standby mode on the standby mode display unit before the time count reaches a predetermined time.

A television receiver comprising:
- a receiving unit configured to receive a television broadcast and output a-video signal and an audio signal;
- a video display unit configured to display an image based on the video signal output from the receiving unit;
- an attenuation unit configured to attenuate the video signal output from the receiving unit;
- a power circuit;
- a power switch command unit configured to issue a command to turn on the power circuit for supplying the operating power to the video display unit on one hand and to turn off the power circuit for suspending the supply of the operating power to the video display unit on the other hand;
- a time counting unit;
- a standby mode display unit;
- and
- a control unit configured to switch on/off the power circuit in response to the power switch command from the power switch command unit, detect the command to turn off the power circuit and drive the attenuation unit to attenuate and display the video signal on the video display unit before the power circuit turns off, cancel the attenuation mode of the video signal by detecting the command to turn on the power circuit, detect the command to turn off the power circuit from on state to start the time counting operation on the time counting unit, and display the standby mode on the standby mode display unit before the time count reaches a predetermined time.

A method of controlling a television receiver comprising:
- a first step of receiving a television broadcast and outputting a video signal and an audio signal;
- a second step of displaying an image based on the video signal outputted in the first step on a video display unit;
- a third step of issuing a power switch command for turning on a power circuit to supply the operating power to the video display unit on one hand and turning off the power circuit to suspend the supply of the operating power to the video display unit on the other hand;
- and
- a fourth step of switching on/off the power circuit in response to the power switch command, detecting the command to turn off the power circuit to mute the audio signal before the power circuit turns off, canceling the mute mode of the audio signal by detecting the command to turn on the power circuit, detecting the command to turn off the power circuit to start the time counting operation, and displaying the standby mode until the time count reaches a predetermined time.
