Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a flowchart of channel selection according to the present invention, FIG. 2 is a simplified diagram showing a change in screen in channel selection according to the present invention, and FIG. 3 is a perspective view of a remote controller used for channel selection according to the present invention.

2 and 3, FIG. 2A shows a normal reception state of the television receiver. For example, it is assumed that a total of 12 stations can be received from station a to station l 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 channel selection mode. In this embodiment, this change instruction is
It is issued by touching a trackball, a cross cursor key or a joystick lever on the remote controller shown in FIGS. 3A-2, 3B-3 and 3C-4. 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 at the upper left quarter of the screen (hereinafter, the upper left 4 d).
One-half of the moving image is referred to as a “temporary selection screen”). At the same time, the other tuner (hereinafter referred to as "tuner 2") sequentially saves the images of all the 12 stations being broadcast at that time as still images having a size of 1/8 of the entire screen in the image memory. , 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 further displays a cursor frame in this portion (hereinafter, the moving image in the cursor frame is referred to as a “search screen”). . FIG. 2B shows a screen immediately after the mode is changed to the channel selection mode (hereinafter, a state in which the provisional channel selection screen matches the search screen is referred to as a “provisional channel selection state”). Thereafter, when the track frame 2 on the remote controller is rotated, the cross cursor key 3 is pressed, or the joystick lever 4 is depressed to move the cursor frame on the screen in station units, the cursor frame on the screen on which the cursor frame has moved is displayed. 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 which was the search screen until that time is changed to a still image. C in FIG. 2 indicates that the cursor has moved to the j-station portion and that this screen is a search screen (hereinafter, a state where the provisional channel selection screen and the search screen are different is referred to as a “search state”. Name).

In the search state, when a confirmation instruction is transmitted by pressing a confirmation instruction button on the remote controller shown in 5 of FIG. 3, the tuner 1 receives the j-th station and temporarily selects a station in the upper left quarter. The screen is replaced with the j station, a moving image is displayed, and the state is again temporarily selected. Here, when the confirmation instruction is transmitted again by the remote controller, the tuning is completed and the entire screen is switched to the j station. FIG. 2D and FIG. 2E show that the j station in the provisional channel selection state has been selected. If it is desired to select another station without terminating the channel in the temporary channel selection state, if the cursor is moved without issuing a confirmation instruction, the search screen is again in a search state different from the temporary channel selection screen. F in FIG. 2 indicates that the state has been changed from the temporary channel selection state to the search state again, and the search screen has been changed to the station a. Further, G in FIG. 2 and H in FIG. 2 indicate that station a is provisionally selected from the search state and displayed on the provisional selection screen portion, indicating that station a is finally selected. It goes without saying that stations other than the j station and the a station can be selected in a similar manner.

FIG. 1 is a flowchart summarizing the above-mentioned tuning operation. In this embodiment, since there are two tuners, the reception work of a plurality of stations can be performed by the two tuners at the time of simultaneous display of a plurality of stations. This makes it possible to display a plurality of screens at high speed.

In the above-described embodiment, an example in which two tuners are provided has been described. However, according to the present invention, an external input device connected to a television receiver in addition to images of a plurality of stations. For example, by reducing the image of a video tape recorder, a video disk, a cable television, a personal computer, and the like, dividing the image at the same time on one screen, and moving the cursor that displays the divided screen on the screen, the cursor is moved. The station of the image to be shown or an external input may be selected.

[0013]

According to the present invention, the contents of a program desired to be tuned can be known in real time , and
Tuning operation can be performed while checking . Therefore, the user can visually know the contents of the program to be watched (selection desired) in the normal mode before the selection.
The usability of tuning is improved.
