Claim:
A television receiving device comprising: an operating mode determining unit configured to determine an operating mode of the television receiving device; and a power supply control unit configured to automatically turn off the television receiving device in response to a default time elapsing, the power supply control unit further configured to change the default time to a modified time that is shorter than the default time based on the operating mode determined by the operating mode determining unit; and a person detecting unit configured to detect presence of person in a vicinity of the television receiving device using a device other than a remote control even in case of absence of a user operation of the remote control, the operating mode determining unit being configured to determine whether the operating mode is shifted from an ordinary operating mode in which the television receiving device outputs video and audio to a specified mode in response to the user operation of the remote control before the default time elapses, wherein the specified mode is a mode in which there is little possibility of long-term non-operation; wherein the specified mode includes a menu screen display mode in which a menu screen is displayed on the television receiving device, an audio mute mode in which audio output is muted, or a still image display mode in which a still image is displayed on the television receiving device; the power supply control unit being configured to change the default time to the modified time in response to the operating mode determining unit determining that the operating mode is shifted from the ordinary operating mode to the specified mode by the user operation of the remote control, and the power supply control unit being configured to restart measurement of the default time in response to the operating mode determining unit determining that the operating mode is shifted from the ordinary operating mode to a mode other than the specified mode by the user operation of the remote control, the power supply control unit being further configured to turn off the television receiving device in response to the default time elapsing without any user operations of the remote control to the television receiving device being performed, the power supply control unit being further configured not to change the default time to the modified time while the person detecting unit detects the presence of person in the vicinity of the television receiving device using the device other than the remote control, the power supply control unit being further configured to change the default time to the modified time after the person detecting unit no longer detects the presence of person in the vicinity of the television receiving device.
