A television including a CS digital circuit to receive a CS digital television broadcast signal. A micom circuit detects a broadcast mode of the digital television broadcast. Where the broadcast mode is in a first mode, or usual broadcast mode, the power supply to a video output section and audio output section, for example, is turned on to output video images and sound respectively through a CRT and a speaker. Also, where the broadcast mode is in a second mode, or radio broadcast mode, the power supply to the video output section is turned off. Where the broadcast mode is in a third mode, or data broadcast mode, the power supply to both the image output section and the audio output section is turned off. |

DETAILED DESCRIPTION A television receiver according to the present invention, comprises: a first receiving means for receiving a digital television broadcast signal; a video output means for outputting a video image in response to the television broadcast signal received by the first receiving means; a detecting means for detecting a broadcast mode of the digital television broadcast signal received by the first receiving means; and a first control means for enabling or disabling the video output means depending upon the broadcast mode detected by the detecting means.
Specifically, where the broadcast mode includes a first mode including a video signal and a second mode not including a video signal, the first control means including first off means for turning off a power supply for the video output means when the detecting means detects the second mode.
A television receiver, further comprises: an audio output means for outputting audio sound in response to the television broadcast signal received by the first receiving means; and a second control means for enabling or disabling the audio output means depending upon the broadcast mode detected by the detecting means.
According to the present invention, the first control means enables or disables the video output means according to a mode detected by the detecting means.
Where the broadcast mode of a digital television broadcast signal being received is in the first mode, the power, for example, to a display and speaker is turned on to output a video image and an audio sound respectively through the display and the speaker.
Also, where the broadcast mode of a digital television broadcast signal is in the second mode, the power to the display is turned off.
Where the broadcast mode of a digital television broadcast signal is in the third mode, the power to both the display and speaker is turned off.
Consequently, according to the present invention, it is possible to prevent against useless power consumption because the power to the video output means and the audio output means is turned on/off according to a broadcast mode detected
