Digital TV and control method thereof for saving power consumption
First Claim
1. A digital television which receives a broadcasting signal, the digital television comprising:
- a video processing module which reproduces video corresponding to the broadcasting signal;
and an audio processing module which reproduces audio corresponding to the broadcasting signal;
a power source which supplies power;
a controller which determines whether a video signal is included in the broadcasting signal by examining broadcasting information included in the broadcasting signal and controls the power source to interrupt the supply of power to the video processing module if the video signal is not included in the broadcasting signal; and
a broadcasting notification part which outputs an audio broadcasting message which notifies that current broadcasting is audio broadcasting,wherein the controller controls the broadcasting notification part to output the audio broadcasting message if it is determined that the video signal is not included in the broadcasting signal, and controls the power source to interrupt the supply of power to the video processing module if a period of time elapses after the audio broadcasting message is output.
