Patent ID: 7551237

Claim:
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; 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; wherein the power circuit includes a first power circuit configured to supply the operating power to the video display unit and a second power circuit configured to supply the operating power to the receiving unit, and wherein the control unit includes a first determining unit configured to output one logic value during the period when the power switch command unit issues a command to turn on power and during the period before the predetermined time passes from the issue of the command to switch off the power, and output the other logic value for the remaining period, the control unit being configured to output a control signal to turn on the second power circuit during the period when the first determining unit outputs the one logic value, the standby mode display unit being configured to display the standby mode. during the period before lapse of the predetermined time from the issue of the command by the power switch command unit to switch off the power.
