2. Description of the Related Art Conventionally, the mainstream of the channel selection of a television receiver is that the entire screen is changed at once by performing some channel selection operation. The tuning operation is performed by rotating the station display dial built into the television, pressing the station display button (channel button) on the television or the remote controller, or by the up and down buttons on the remote controller. There were many ways to change. As another channel selection method, when a specific channel selection operation is performed, the screen of another station is displayed as a child screen in one corner of the screen, or still images of multiple stations are displayed on one screen at the same time. Although some can be seen, the actual tuning is done by pressing the station display button on the remote controller.
Related patents for this type of device include, for example, Japanese Patent Laid-Open Nos. 62-130080 and 62-21379.

In this case, by providing an image memory and two tuning systems, a total of three or more stations including the station currently being received are reduced and displayed at once. The image of the station received by one tuning system is reduced and displayed as a real-time moving image as the image of the current receiving station, and is displayed larger than the other images. Further, the other tuning system successively receives a plurality of stations including the current receiving station, reduces the size of the received still image in the image memory, and displays it on the screen. At the same time, even with this tuning system, the image of the current receiving station is reduced for the time being and displayed as a real-time moving image with a cursor on the still image of the current receiving station.
Then, when the cursor is moved by using the remote controller, the location of the moving image changes with the movement of the cursor, and by repeating the operation of moving the cursor, the desired station can be made into a moving image. Furthermore, the remote controller can issue a confirmation instruction to change the currently receiving station to the selected station.

2A and 2B, FIG. 2A shows a normal reception state of the television receiver. For example, it is assumed that a total of 12 stations from station a to station l can be received in alphabetical order. It is assumed that the tuner (hereinafter referred to as "tuner 1") is receiving station d therein. Next, the remote controller issues an instruction to change the screen to the tuning mode. In this embodiment, this change instruction is
Issued by touching a trackball, cross cursor keys, or joystick lever on the remote controller shown at 2 in FIG. 3A, 3 in 3B and 4 in 3C. After the change instruction, the tuner that has received the d station until then continues to receive the d station and displays the video as a moving image in the upper left quarter of the screen (hereinafter, this upper left 4
One-half of the moving image is called the "temporary selection screen". At the same time, the other tuner (hereinafter referred to as "tuner 2") sequentially saves the images of all 12 stations being broadcast at that time in the image memory as still images of 1/8 of the full screen. After displaying in the remaining three quarters of the screen,
The tuner 2 also receives the d station, displays the d station portion of the still image as a moving image, and the cursor frame is also displayed in this portion (hereinafter, the moving image in the cursor frame is referred to as a "search screen"). .. The screen immediately after changing to the channel selection mode is shown in FIG. 2B (hereinafter, the state in which the temporary channel selection screen and the search screen match each other is referred to as a “temporary channel selection state”). After that, by rotating the trackball 2 on the remote controller, pressing the cross cursor key 3 or tilting the joystick lever 4, the cursor frame on the screen is moved in units of stations. The tuner 2 receives the station, the screen of the station becomes a search screen and a moving image is displayed, and the moving image of the station that was previously the search screen is changed to a still image. C in FIG. 2 indicates that the cursor is moved to the j station portion and this screen is the search screen (hereinafter, a state where this temporary selection screen and the search screen are different is referred to as a “search state”). Referred to). In the search state, when the confirmation instruction is transmitted by pressing the confirmation instruction button on the remote controller shown by 5 in FIG. 3, the tuner 1 receives the j station, and the temporary selection screen of the upper left quarter is displayed. The station is replaced and the video is displayed, and the station is temporarily selected again. here,
When the confirmation instruction is transmitted again by the remote controller, the channel selection is completed and the entire screen is switched to station j. 2D and 2E show that station j, which was in the tentative channel selection state, has been selected. In the tentative channel selection state, if the user wants to tune to another station without ending the channel selection, the cursor is moved without issuing a confirmation instruction, and the search screen is in a search state different from the tentative channel selection screen. F in FIG. 2 indicates that the state is changed from the tentative channel selection state to the search state again, and the search screen is the station a. Further, G of FIG. 2 and H of FIG. 2 indicate that the station a is tentatively selected from the search state and displayed on the tentative channel selection screen portion, and finally the station a is selected. It goes without saying that stations other than the station j and the station a can be selected by the same method.
