Abstract

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.

Claims

1. A television receiver comprising:

a first receiving means for receiving a digital television broadcast signal;

a second receiving means for receiving an analog television broadcast signal;

a mode setting means for setting an analog receiving mode to receive only the analog television broadcast signal;

a power off means for turning off a power supply for said first receiving means when the analog receiving mode is set;

a reception scheduling means for scheduling to receive a digital television broadcast signal by said first receiving means;

a first power control means for controlling a power to be supplied to said first receiving means in accordance with a scheduled content by said reception scheduling means;

a second power control means for controlling power to be supplied to said video output means in accordance with the scheduled content by said reception scheduling means;

an audio output means for outputting an audio signal of the digital television broadcast signal received by said first receiving means; and

a third power control means for controlling power to be supplied to said audio output means in accordance with the scheduled content by said reception scheduling means.

2. A television receiver according to claim 1, wherein when the scheduled content by said reception scheduling means is a view scheduling to view at a particular time a particular program of the digital television broadcast and that time is reached, said first power control means, said second power control means and said third power control means respectively supply power to said first receiving means, said video output means and said audio output means.

3. A television receiver according to claim 1, further comprising:

an externally output means for externally outputting the digital television broadcast signal received by said first receiving means;

an external output control means for enabling said external output means when the scheduled content by said reception scheduling means is a view-and-record scheduling to view and record at a particular time a particular program of the digital television broadcast and that time is reached.

4. A television receiver according to claim 3, wherein said external output control means enables said external output means when the scheduled content by said reception scheduling means is a record scheduling to record at a particular time a particular program of the digital television broadcast and that time is reached, and further

when the particular time is reached said second power control means and said third power control means respectively cutting off power to said video output means and said audio output means.
