Abstract

PURPOSE:To offer a multi-screen display television receiver convenient to a viewer by displaying the information relating to a broadcast channel and a broadcast such as voice multiplex broadcast at each display scope so as to confirm the information on the screen at a glance. CONSTITUTION:The display representing the number of a broadcast channel and a stereo broadcast is added to each screen by a channel selection switching section to attain multi-scope display as shown in Fig. That is, a numeral [4] is displayed on the display scope P1 and this represents that the scope P1 receives the broadcast of the 4th channel. Further, a numeral [10] and a character of ''stereo'' are displayed together on the display scope P2 and this means that the screen P2 receives the broadcast of the 10th channel and the sound broadcast is the stereo broadcast. Thus, a viewer can confirm visually easily the broadcast channel of each display scope and whether or not the broadcast is the stereo broadcast.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a multi-screen display television receiver that displays two or more different images on one display device.

[Prior art] Conventionally, there was a device of this type as shown in Fig. 30.
In the figure, (1) is the tuner, (2) is the tuning section, and (3
) is the channel selection switching section, (4) is the video detection circuit, (5) 4*A
D converter, (6) is memory control section, (7) is memory section, (8) is DA converter, (9) is signal processing section, (
10) is an image display section.

Next, the operation will be explained. Broadcast radio waves from the outside are received by a tuner (1). The receiving channel is selected by the tuning section (2
), but this channel is controlled and switched by the channel selection switching section (3). The output of the tuner (1) is demodulated into a video signal by the video detection circuit (4), and
It is converted into a digital signal by a D converter (5).

46 input in the memory control unit (6)
The number is stored in the memory section (7). When one screen of one channel has been stored, the next channel is selected by the channel selection switching section (3), and the video signal is stored in the memory section (7) in the same process as described above.

These operations are repeated for the designated number of screens, and the video signals are sequentially stored in the memory section (7).

Next, the memory control unit (θ) converts the time and reads the memory contents, and the signal processing unit (9) and image display unit (lO) process the P1 to P1 as shown in FIG.
A multi-screen consisting of 4 is displayed.

In this example, the number of screens is four, and each image is a still image corresponding to the switching time.

However, the above-mentioned conventional multi-screen display television receiver has the disadvantage that it is difficult to tell which channel's broadcast is being received on each of the display screens P1 to P4, and whether it is an audio multiplex broadcast.

[Summary of the Invention] This invention was developed to solve the above-mentioned conventional drawbacks, and provides information such as broadcast channels and audio multiplex broadcasts on each display screen for the convenience of viewers. The purpose of this invention is to provide a multi-screen display television receiver.

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

FIG. 1 is a block circuit diagram showing an embodiment of a multi-screen display television receiver according to the present invention.

In the figure, the same parts as in Figure 3 are given the same reference numerals.
The explanation will be omitted. In FIG. 1, a signal detection circuit (11), a character generation circuit (12), a character mixing circuit (13), and a voice detection circuit (14) are newly added to the configuration of FIG. 3.

Next, the operation will be explained. The process from the reception of broadcast waves to the multi-screen display by each section (1) to (10) is exactly the same as the conventional case shown in FIG.

The signal detection circuit (11) detects the channel selected by the channel selection section (2) and causes the character generation circuit (12) to generate a number corresponding to the broadcast channel. For example, if channel 4 is selected, the character r4J will be generated from the character generation circuit (12), and the number generated from the 0 character generation circuit (12) will be controlled in memory via the character mixing circuit (13). The information is input to section (6).

On the other hand, the audio detection circuit (14) determines whether the audio broadcast is a multiplex broadcast, and transmits the determination content to the signal detection circuit (11).
send to At this time, if the audio broadcast is, for example, a stereo broadcast, the character "stereo j" is generated from the character generation circuit (12) and inputted to the memory control section (8) via the character mixing circuit (13).

The above operation is performed for each screen by the channel selection switching unit (3), and displays such as the broadcast channel number and the fact that it is a stereo broadcast are added to each screen to display a multi-screen display as shown in Fig. 2, for example. .

In FIG. 2, the number r4J is displayed on the display screen P1, which indicates that the screen P1 is receiving broadcasts of 4 channels. In addition, the numbers i'lOJ and the letters "stereo j" are displayed together on the display screen P2, which means that the screen P2 is receiving broadcasts from 10 channels and the audio broadcasts are stereo broadcasts. This allows the viewer to easily visually confirm the broadcast channel of each display screen, whether or not it is a stereo broadcast, etc.

In the above embodiment, the case where the number of screens is four is shown, but any number may be used as long as there are two or more screens. Further, the display content is not limited to broadcast channels and audio display, but may also indicate the type of video (here, "video j") as shown in display screen P4 in FIG. 2, for example.

Further, in the above embodiment, each image is a still image, but the present invention can also be applied to a moving image system.

[Effects of the Invention] As described above, according to the multi-screen display television receiver according to the present invention, information regarding broadcasting, such as broadcasting channels and audio multiplex broadcasting, is displayed on each display screen. This information can be confirmed at a glance, thereby providing a multi-screen display television receiver that is convenient for viewers.
