The video input signals are output to the specific screen information detection circuits 3-1 to 3-N, respectively.
To supply. First to N-th user-set keywords are input to the input terminals 2-1 to 2-N, respectively. These first to N-th user-set keywords are respectively input to the keyword input circuit 4.
-1 to 4-N.

The keyword input circuits 4-1 to 4-N generate information (hereinafter, referred to as keyword information) based on the first to Nth user-set keywords input based on user operations, respectively, and generate a keyword detection circuit 5. Output to -1 to 5-N. The specific screen information detection circuits 3-1 to 3-N detect a character string included in an image based on the input first to Nth video input signals, and detect information of the detected character (hereinafter referred to as screen character information). To the keyword detection circuits 5-1 to 5-N.

The keyword detecting circuits 5-1 to 5-N compare each piece of keyword information based on the user setting with each piece of screen character information, and convert the first to Nth images into images based on the first to Nth video input signals, respectively. It detects whether or not an image of a character including the N user setting keyword is included, and if so, outputs a coincidence signal to the display mode control circuit 6.

The display mode control circuit 6 has a screen parameter setting section 7. The screen parameter setting unit 7 sets screen parameters for controlling a screen display mode of a display unit (not shown). The screen parameter setting unit 7 sets the screen parameters based on a user operation of an input device such as a remote controller (not shown), and sets the screen parameters based on the outputs of the keyword detection circuits 5-1 to 5-N. As screen parameters,

The display form control circuit 6 also receives the first to N-th video input signals.
Based on the selection 1 to N parameters and the processing 1 to N parameters, a video signal to be displayed on a screen in a desired display form is created using the video input signal selected from the first to Nth video input signals. Output as a video output signal.

Next, the operation of the embodiment configured as described above will be described with reference to FIGS. FIG. 2 is an explanatory diagram for explaining the operation of the embodiment, and FIG.
Is a flowchart for explaining the operation of the embodiment.

First to N-th video input signals are input to input terminals 1-1 to 1-N, respectively. These first to N-th video input signals are supplied to the display mode control circuit 6. In step S1 in FIG. 3, the user selects a desired program and displays it on the screen in a desired display form. That is, the screen parameter setting unit 7 of the display mode control circuit 6 sets a selection parameter and a processing parameter based on a user's remote control operation or the like. The display mode control circuit 6 combines the selected video input signals based on the selected parameters and the processing parameters so as to be displayed in a specified display mode, and outputs the resultant as a video output signal. This video output signal is supplied to the display unit to perform a desired display.

The display specified by the user is shown in FIG.
(A). On the display screen of the display unit, three small screen displays are displayed at the right end, and a main screen of a predetermined program is displayed at the center. For example, the parent screen is a "Sumo" program, and one of the child screens is a "Baseball" program.

By the way, it is difficult to predict when and what kind of scene will appear in a live broadcast program, particularly in a sports broadcast such as baseball and sumo. However, for example, which person or character appears can be searched if the person on the screen and the superimposed displayed on the screen temporally match. In live broadcasts such as baseball and sumo wrestling, each time a player or wrestler appears, a caption for that introduction is displayed on the screen.

Therefore, for the relay screen among the plurality of displayed screens, the names of the players or wrestlers that the player wants to see are input in advance as a keyword, and the keyword is continuously searched during the relay. If the keyword matches the character of the caption on the screen, that is exactly the scene desired by the user. At this coincidence timing, automatic control is performed to change the display to a desired display.

That is, first, in step S2, the user sets a keyword for each displayed screen. Further, a process for designating a display mode is set corresponding to the keyword (step S3). The keyword set for each screen (video input signal) is supplied to a keyword input circuit. The keyword input circuit outputs the keyword information to the keyword detection circuit.

For example, “sumo” in FIG.
It is assumed that the program C and “baseball” are based on the first to fourth video input signals, respectively, and that the user inputs “OOOO” indicating a person name as the fourth user setting keyword. It is also assumed that a process for enlarging and displaying a parent screen is set in accordance with the keyword.

In step S4, a keyword detection process is started. That is, the specific screen information detection circuit 3-4 is the fourth
Given a video input signal, a character example included in an image based on the video input signal is detected, and screen character information is output to a keyword detection circuit 5-4. Keyword detection circuit 5-4
Compares the screen character information with the keyword information,
It is detected whether or not the character string of “○” is displayed during the “baseball” program based on the video input signal.

As described above, in sports broadcasting and the like, when a player appears, the name of the player is displayed in subtitles. When the character string of "XXX" is displayed in subtitles, in step S5, the keyword detection circuit 5-4 outputs a coincidence signal indicating that the keyword has been detected. The display form control circuit 6 controls the fourth
Process 4 for setting screen display based on video input signal
Generating parameters and combining the video input signal based on each selection and processing parameter to generate a video output signal.

In this case, since the process for enlarging and displaying the main screen by detecting the keyword of "XXX" is designated, as shown in FIG. The "baseball" program is displayed on the main screen (step S6). If the other settings have not been changed, the “sumo” program displayed on the main screen is displayed on the small screen instead of the “baseball” program.

Conversely, it is also possible to set so that the program displayed on the main screen is displayed on the sub-screen. FIG.
(C) and (d) show examples in this case. For example, in the "Sumo" program, "xxxx" is set as a keyword, and a process for reducing the size and displaying a small screen corresponding to the keyword is set.

In this case, during the "Sumo" program, "XXX"
When the subtitle “X” is displayed, the program of “Sumo” displayed on the main screen is displayed on the sub-screen as shown in FIGS. 2 (d) by setting the parameters of the screen parameter setting unit 7. You. When the setting for displaying another program on the main screen is not made, no image is displayed in the display area of the main screen as shown in FIG.

As described above, in the present embodiment, when the keyword set by the user is included in the characters displayed on the screen, the screen display is automatically set to the display mode set corresponding to the keyword. Change. Thereby, usability can be significantly improved.

In this embodiment, the display mode is controlled by detecting the characters displayed on the screen. However, it is apparent that the display mode may be any other than a character as long as the display is recognizable.
Various characters may be detected, and a specific pattern may be detected.

Also, an example has been described in which the first to N-th user-set keywords are set for each of the first to N-th video input signals, but a common user-set keyword is set for a plurality of video input signals. You may do so.

FIGS. 4 and 5 are an explanatory view and a flowchart for explaining a display method according to an embodiment of the present invention. 5, the same steps as those in FIG. 3 are denoted by the same reference numerals, and description thereof will be omitted.

This is to automatically return to the original display.

For example, when a scene in which a wrestler who wants to see is detected in a sumo broadcast is detected, the screen size is changed to a desired screen size, and the user watches the initiative, after the wrestler's initiative is completed, the meaning of the wrestler does not have much meaning for the user. It is conceivable that there will be no screen configuration. Generally, the time required for sumo wrestling is about 2 to 5 minutes. Therefore, after this time has elapsed since the change of the display mode, another approach is taken, and thereafter, the original screen configuration is restored.

That is, when a keyword is set in step S2 in FIG. 5, a process is specified in step S11 in correspondence with the keyword. In this case, the time until automatically returning to the original display form is also specified. Now, assuming that the display mode is as shown in FIG. 4 (a), and when the subtitle "OOOO" is displayed on the sub-screen displayed "Sumo" program, the "Sumo" program is expanded. The parent screen is displayed, and after a predetermined time has elapsed, the display is returned to the original display form.

The "Sumo" program displayed on the child screen is marked with "○
When "○○○" is displayed, the keyword is detected in step S5 in FIG. 5, and the display is changed to the display shown in FIG. 4B in step S6.

In the present embodiment, the following step S
