BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-screen display device.

[0002]

2. Description of the Related Art Conventionally, when watching a program broadcast on each channel by a TV (television) receiver, 1
It can only be viewed on each channel, and if you want to know what programs are being broadcast on other channels, the only way is to look at a different channel or look up in the program table of newspapers and magazines Did not. But,
The former method takes a long time because all channels are changed and watched, and if a commercial is broadcast when watching a certain channel, it is necessary to wait for the commercial to end without knowing the program, which is troublesome. Was. In addition, it was troublesome to check in a program table of newspapers and magazines.

For this reason, some TVs and VTRs have a function of displaying the broadcast of each channel on a multi-screen, so that each channel can be displayed simultaneously, and at this time, the channel is displayed on each screen. You can see how many channels each screen is.

[0004]

[Problems to be Solved by the Invention] However, the above-described means can only determine the channel of the program, and it is still necessary to check the program table or determine from the video to know the contents of the program. The hassle did not change.

Therefore, the present invention is to solve such a drawback.

[0006]

According to the present invention, there is provided a multi-screen display device comprising: program information extracting means for extracting, as program information, a program classification based on program contents inserted during a vertical blanking period of a television signal; Storage means for storing program information extracted by the program information extracting means, receiving means capable of simultaneously receiving programs on a plurality of channels, and display for displaying the programs on the plurality of channels received by the receiving means as a multi-display screen Means, for each of the multiple display screens displayed by the display means,
Superimposing means for superimposing and displaying each program information read from the storage means; detecting a program belonging to a designated program class based on the program information in the storage means; And control means for performing display according to (1).

[0007]

According to the present invention, the contents of a plurality of programs currently being broadcast can be simultaneously known. Also, since only the programs belonging to the designated program category are displayed on the multi-screen with the program information superimposed, only those of the program category desired to be viewed are displayed on-screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 3, a television signal caught by an antenna 8 is received by a television signal receiving circuit 1 having a plurality of tuners and converted into a predetermined intermediate frequency signal. It is supplied to the broadcast decoder 2. The teletext decoder 2 is a teletext signal inserted into the television signal during the vertical blanking period, which is related to program information, for example, information indicating a program table, program classification (title), and program contents (program name). Is extracted and stored in the storage circuit 3.

On the other hand, a multi-screen display circuit 4 outputs a multi-screen signal for displaying a television signal of each channel obtained from the television signal receiving circuit 1 on a monitor 6 via an on-screen circuit 5. In this manner, for a plurality of images displayed on the monitor 6 on the multi-screen, the program information corresponding to the displayed image is read out from the program information stored in the storage circuit 3 in advance, and the teletext decoder 2 Is supplied to the on-screen circuit 5 via the multi-screen signal, and is superimposed on each screen signal of the multi-screen signal.

Reference numeral 7 denotes a control circuit which selects a command to the television signal receiving circuit 1, detects data belonging to the class at the current time when a program class described later is designated from the outside, and displays a multi-screen. The number of screens displayed by the circuit 4 and the display position of data in the on-screen circuit 5 are controlled.

Next, the specific operation of the device of the present invention will be described with reference to FIG.
This will be described with reference to FIG. In the following description, it is assumed that the program information is stored in the storage circuit for all channels in advance.

First, a case where multi-display is performed in the order of channel numbers as shown in FIG. 1 will be described. In FIG. 3, the control circuit 7 controls one tuner of the receiving circuit 1 so as to select the first channel. . And
This image is displayed in the screen area (1ch in FIG. 1) corresponding to the first area of the memory of the multi-screen display circuit 4. Similarly, the control circuit 7 controls the other tuners of the receiving circuit 1 so as to select the channel on the second channel. Then, this video is displayed in a screen area (2ch in FIG. 1) corresponding to the next area of the memory of the multi-screen display circuit 4. Such an operation is performed for the number of screens displayed in multi-display.

Next, for each screen, from the data of the current time and the channel, the classification and content of the program of the screen among the data stored in advance in the storage circuit 3 are detected. An on-screen display is superimposed on the image on the monitor 6. This is repeated for the multi-screen display. In this way, the images of all channels at the current time are multi-displayed, and the channel, classification (title), and contents of the program are displayed on the screen. Therefore, a program to be viewed can be selected at any time in accordance with the video, the classification of the program, and the content. If a program to be viewed is found, it can be viewed on a normal screen (one screen) by specifying the channel.

Next, a case of multi-display according to program classification will be described. By specifying the program classification for the currently broadcast program, the program data stored in advance in the storage circuit 3 is used to determine the channel of the program belonging to the specified classification among the currently broadcast programs. And the number are detected. In accordance with this data, the control circuit 7 controls the receiving circuit 1 and the multi-screen display circuit 4, and only the programs belonging to the specified classification are displayed as shown in FIG. At the same time, the contents of channels and programs are displayed on each screen.

[0016]

As described above, according to the present invention, when a currently broadcast program is displayed on a multi-screen, it is possible to easily know which channel and what program content is being broadcast. it can. Also, since only the programs belonging to the specified program category are displayed on the multi-screen with the program information superimposed, only the programs of the desired program category are displayed on the screen, and unnecessary programs are not displayed on the screen and the program can be selected. It can be done more easily.
