It is controlled to suppress the driving of the unit 23.

Next, an embodiment according to the present invention will be described in more detail with reference to the flowchart of FIG. 2.

First, when the power is turned on by the user (ST1 step), the controller 10 controls the input power to be supplied by driving control of a relay (not shown) and is stored in the channel memory 19. The first and second tuners 2 and 5 are tuned and controlled based on the channel data. The broadcast signals tuned through the tuners 2 and 5 are respectively subjected to video IF processing and audio IF processing. Also, the video signals are processed through the video processing unit 16 and the audio signals are transmitted through the audio processing unit 12, respectively. Processing is performed to output to the speaker 14 and the CRT 18.

At this time, the controller 10 initializes the first timer 21 and performs count control (step ST2).

Thereafter, when a predetermined power-on elapsed time display function is selected by the user (step ST3), the controller 10 searches for the time currently counted by the first timer 21 and generates the OSD based on the detected time. The drive 23 is controlled to output an OSD elapsed time message, for example, the current viewing time is 00: 00 (ST4 step).

In addition, the controller 10 controls the output of the OSD message and initializes the second timer 22 and then performs count control (step ST5).

The controller 10 continuously searches for a signal input from the second timer 22 while controlling the output of the OSD message. In this case, a predetermined count end signal is input from the second timer 22. In step ST6, the operation of the OSD generator 23 is suppressed to release the output of the OSD signal according to the display of the elapsed time (step ST7).

That is, according to the embodiment, the user can easily know the time elapsed from the time when the power of the television receiver is turned on at the time desired.

On the other hand, the present invention is not limited to the above embodiments and can be modified in various ways without departing from the technical gist of the present invention.

As described above, according to the present invention, a television receiver having a power-on elapsed time display function for counting a time from the time when the power is turned on and displaying an elapsed time after the power is turned on at a desired time by the user. It can be realized.
