The third process; If a key signal for channel selection is not applied even after a predetermined time has elapsed, the screen displayed in the third step is stopped, and if there is a next channel, the broadcast signal applied to the next channel is screen-divided and displayed in the divided next position. A fourth process of returning to the second process if the channel displayed in the third process is the last channel; When the key signal for channel selection is applied, a display method for channel selection in a television, comprising a fifth step of releasing and displaying a broadcast signal applied in synchronization with a channel corresponding to an applied key signal.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a television according to the present invention, which includes a key input unit 10, a microcomputer 20, a memory 30, a tuner 40, a SIF 50, an amplifier 60, and a VIF 70. ), An A / D 80, a PIP processing unit 90, and a D / A 100.

In the figure, the key input unit 10 is an input means for controlling the operation of the television, and is provided with a plurality of keys such as a power key, a channel up / down key, a channel selection key, a numeric key, and the like. Outputs a key signal.

Then, the microcomputer 20 controls the operation of the television corresponding to the key signal from the key input unit 10, the memory 30 is stored in the channel frequently watched by the user based on the control of the microcomputer 20 It is remembered / read.

In addition, the tuner 40 tunes to a channel corresponding to the tuning signal from the microcomputer 20 to receive and output a broadcast signal induced by the antenna.

On the other hand, the SIF 50 converts the voice signal from the broadcast signal from the tuner 40 to the voice intermediate frequency and outputs it, and the amplifier 60 amplifies the voice signal from the SIF 50 and applies it to the speaker SP. do.

The VIF 70 converts the video signal from the broadcast signal from the tuner 40 to the video intermediate frequency and outputs the video signal. The A / D 80 converts the video signal from the VIF 70 into a digital signal and outputs the digital signal. do.

In addition, the PIP processing unit 90 divides the digital video signal from the A / D 80 into a predetermined position and size based on the PIP control signal of the microcomputer 20, that is, PIP (Picture in Picture) processing and RGB. Process and output

Meanwhile, the D / A 100 converts the digital video signal from the PIP processing unit 90 into an analog signal and applies it to the CRT.

Next, a preferred embodiment of the present invention in a television configured as described above will be described with reference to the flowchart of FIG.

First, the microcomputer 20 determines whether a key signal for power-on is applied from the key input unit 10 (step 200).

At this time, when the power key is pressed by the user and the key signal for power-on is applied, the microcomputer 20 reads the channels (four channels in the present invention) that the user frequently watches from the memory 30 (step 202). .

At this time, the channel frequently used by the user is preset and stored in the memory 30, and the user may arbitrarily select and store the channels that the user wants to select. 20) may be determined and stored.

Next, the microcomputer 20 applies a tuner signal corresponding to the lowest channel among the channels that the user frequently watches to the tuner 40 (step 204).

Then, the SIF 50 separates the voice signal from the broadcast signal applied from the tuner 40, changes it to the voice intermediate frequency, applies the amplifier signal to the amplifier 60, and amplifies the voice signal applied by the amplifier 60. The user can listen through the speaker SP.

In addition, the VIF 70 separates the video signal from the broadcast signal applied from the tuner 40, converts the video signal to an image intermediate frequency, and outputs the digital signal. The A / D 80 digitally converts the video signal from the VIF 70 to PIP. It applies to the processing part 90.

Then, the PIP processing unit 90 divides the digital video signal from the A / D 80 into the corresponding position and size based on the PIP control signal from the microcomputer 20 and performs RGB processing to the D / A 100. The D / A 100 converts the digital video signal from the PIP processing unit 100 into an analog signal and applies it to the CRT (step 206), so that the user can view the screen.

Next, the microcomputer 20 checks whether a predetermined time has elapsed (step 208), and when the predetermined time has elapsed, the screen of the channel being divided and displayed in step 206 is stopped (step 210).

The above-mentioned method of stopping a split screen can be implemented by storing a predetermined frame (one frame) of an image signal input to the PIP processing unit 90 in a memory in the PIP processing unit 90 and repeatedly applying it repeatedly.

Next, it is determined whether there is a next channel that the user frequently watches (212), and if there is a next channel, the tuner 40 applies a tuning signal corresponding to the next channel (step 214), and returns to the step 206. Screen division is performed on the next position to display an image signal applied from the tuner 40.

At this time, all the channels frequently watched by the user are in the state of being stopped at the corresponding position on the screen, and the image of the next channel is displayed at the corresponding position, and the audio of the next channel is also added to the SIF 50, the amplifier 60, and the speaker ( Output via SP).

Next, if step 206 is repeated in step 214, and if it is determined that the channel is the last channel in step 210, the process returns to step 204 to switch the lowest channel frequently watched by the user back to the active state. Repeat (214) to (214).

As described above, the present invention divides and displays a screen on one screen while repeatedly tuning a channel frequently used by a user at a predetermined time interval.

On the other hand, if the user presses the channel selection key or the numeric key of the key input unit 10 before the predetermined time elapses in step 208, the microcomputer 20 receives the input channel selection key signal or the numeric key signal. This is determined (step 216).

At this time, when a key signal for channel selection is applied, the tuner 40 is tuned to a channel corresponding to the applied key signal to control the PIP processing unit 90 to release the divided screen and output the screen signal on one screen. (Step 218).

As described above, according to the present invention, a plurality of channels that the user desires or frequently watches are alternately displayed on one screen in the initial stage when the TV is turned on, so that the user can individually use the channel up / down keys. Instead of selecting the channel that you want to watch, you can easily select the channel that you want to watch by simultaneously viewing several channels that are displayed on the screen and are sequentially displayed on one screen.
