Then, as shown in FIG. 3 (b), the video of the channel with the highest priority, for example, the eighth channel is displayed in the main display area 30, and the sub-display areas 31, 32, and 33 are displayed in the sub-display areas 31, 32, and 33, respectively. , The eighth displayed in the main display area
For example, the fourth channel, the sixth channel, and the
It is displayed like 12 channels. This main display area 30
Is displayed in the main display area 30, which is the image displayed in the sub-display area 31 as shown in FIG. 3 (c), for example, after being displayed for one second, for example. The video is switched to the video of the fourth channel having the largest number of selections after the eighth channel. At the same time, the sub display area
For example, the video of the sixth channel displayed on 32 is displayed on the sub-display area 31 and the twelfth video displayed on the sub-display area 33.
The video of the channel is shifted to the sub display area 32 and displayed. The sub-display area 33 includes the sub-display area 32
For example, the image of the 15th channel of BS, which has the second largest number of tunings after the twelfth channel displayed and displayed, is newly displayed.

When performing this panning, it is preferable that the main display area 30 and the sub display areas 31, 32, 33 are not displayed because the program of the original channel is recognized.

In step 54, 1 after the CM key 28 is turned on, that is, after the above-mentioned panning is started.
It is determined whether or not minutes have elapsed, and if yes, step 6
Proceed to 1; if No, proceed to Step 56.

In step 56, the panning is started, and it is determined whether or not all the images of the channels other than the original channel stored in the channel data memory 29 have been displayed.
In the case of, the process proceeds to step 61, and in the case of No, the process proceeds to step 57.

In step 57, it is determined whether or not the CM key 28 has been turned on again. If the answer is Yes, the process proceeds to step 61;

In other words, commercials generally take 30 seconds to
Since the broadcast is often performed for about one minute, the television receiver of the present embodiment sets the time of the panning mode to, for example, 1 minute.
And when this one minute elapses, in step 61, the CPU 4 reads the data of the original channel from the channel data memory 29, and selects the original channel in response to the read data. 4th tuner
The channel selection operation of any one of 2, 3, 13, and 14 is controlled. In this case, the first tuner 2 or the second tuner 3 is controlled to select the first channel, and
As shown in FIG. 3 (d), the image of the first channel which is the original channel is displayed on the CRT 21. Also, the above CM
The key 28 supplies, for example, a specific operation signal for specifying the start of the panning mode to the CPU 4 when turned on once, and specifies the panning mode and stop when the key 28 is turned on again while the panning is being performed. Is supplied to the CPU 4. When the CPU 4 is supplied with the specific operation signal designating the stop of the panning mode, the CPU 4 tunes and displays the original channel selected before starting the panning in step 61.

Note that the routine of steps 53, 54, 56, and 57 described above is repeated during this panning.

Here, in step 54, the one minute has elapsed since the transition to the panning mode, and the panning mode automatically ends. During this one minute, the images of all selectable channels are displayed. It cannot always be displayed. Therefore, in step 61, the panning is automatically terminated, and the original channel is selected.

In the above step 55, it is determined whether or not the CM key 28 is turned on within 10 seconds after the original channel is tuned in the above step 61.If Yes, proceed to Step 58; if No, proceed to Step 58. The process returns to step 51 described above.

In step 58, the channels not selected in the previous panning mode are selected according to the priority order, and the process proceeds to step 59.

In step 59, it is determined whether or not all channels other than the original channel have been selected.If Yes, the process proceeds to step 61, where the original channel is selected as described above, and If so, go to step 60.

In step 60, it is determined whether the CM key 28 has been turned on again. If the answer is Yes, the process proceeds to step 61, where the original channel is tuned as described above.
