JPH04117783A - Simultaneous display device of tv multi-pattern - Google Patents

Abstract

PURPOSE:To eliminate the need for installation of lots of tuners and to reduce the cost by devising the display device such that patterns of lots of broadcast stations are simultaneously observed on one and same screen with one tuner. CONSTITUTION:When a viewer selects the mode of simultaneous display of lots of patterns in advance, a microcomputer 6 is active and a tuner 1 is used to tune a radio wave of one channel set usually. A tuned signal is fed to the microcomputer 6, which allows a storage device to prepare acceptance of lots of data when the mode of simultaneous display of lots of patterns is selected. Only a picture signal is selected from the sent signal and stored as a still picture and it is displayed on the screen through a controller 2. When the same procedure is repeated again from the channel, each pattern is being changed as if strobo pickup were adopted. Thus, patterns of lots of broadcast stations are simultaneously observed on one and same screen with one tuner and the cost of the product is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is to simultaneously divide and display screens of a large number of broadcast stations on a television screen.

(b) Conventional technology and problems Conventional televisions can only display one broadcast on one screen. When I watched TV, I looked at the IfI section of newspapers and television programs, decided on the channel, and watched the program. If the program section was not available, the user would switch channels and search for the desired program. In this case, if commercials are also being broadcast, it will take more time to search for them, and if you want to see breaking news such as typhoons, earthquakes, major accidents, etc. that are not listed in the program column, you may have to search multiple times. Sometimes I change channels.

Conventional televisions have one tuner and can be viewed at the same time either on one screen or on multiple divided screens of the same broadcast screen.

In order to view the screens of many broadcast stations on the same screen, it was necessary to have the same number of tuners as the screens to be displayed. Attaching a large number of tuners increases the size and the cost of the product.

(Il) Means for trying to solve the inter-M point Diagram 1 is 18 diagrams of a normal television. Normally, the radio waves received by the antenna in ■ are tuned by the tuner in ■, and the signal is
The image on the TV screen of ■1 is controlled by the TV control device of
It becomes an audio signal to speakers No. 8 and ■ and is broadcast.

FIG. 2 shows an example of a multi-screen display device using a microcomputer (hereinafter abbreviated as microcomputer). In this case, it seems appropriate to divide the screen into three vertically and four horizontally as shown in Figure 3.

First, the viewer selects 12-screen display in advance. The microcomputer (■) works and tunes to the 1-channel radio wave normally set by the tuner (■). Send the synchronized signal to the microcontroller (■). The microcomputer ■ prepares to receive 12 data in the storage device from the time the 12-screen display is selected. The sent signals are selected as much as the image f9 signal, stored as a still image, and displayed on the screen (2), at the location (2) in Figure 3, through the control device (2).

The microcontroller (2) starts tuning the tuner for the 2nd channel from the moment the 1st channel image signal is memorized. The synchronized No. 18 is sent again to the microcomputer in ■, stored as a still image in the storage device, and the process continues as shown in Figure 3 (■).
Project it on the screen.

This process is repeated until 12 channels are displayed, and all screens are displayed.

While going from channel 1 to channel 12, the time was taken lightly and the screen changed, so I went back to channel 1.
Repeat the same thing from the channel. By doing so, each screen changes as if it were photographed with a strobe light.

Considering that the screen size of the data input to the storage device will be smaller, if data is thinned out by omitting part of the data, each response time will be shortened and the image will not deteriorate in particular.

In addition, microcomputer control allows 2 screens, 4 screens, 6 screens, 8 screens,
If 9-screen display can be selected, the response time is one hour less than 12-screen display, so you can see static screens that change less over time.

By attaching this device to a video tape recorder connected to the television and interlocking with the television, you can obtain the same effect as if you attached it to the television itself.

In addition to this, there is also a tuner dedicated to displaying multiple screens.

Or increase the number of dedicated tuners. Alternatively, by linking with an existing tuner or a tuner such as a connected video tape recorder, you can further increase the 11FR.
You can see the screen with little change.

(c) Function By doing the above, it is possible to simultaneously view the screens of many broadcasting stations on the same screen using a single tuner. It eliminates the need to install multiple expensive tuners and saves space. There are few viewers who want to know all the contents of a large number of broadcasts at the same time, and many people who only want to know what is being broadcast on other channels.

You can set up multiple screens at times when elections, typhoons, earthquakes, major accidents, etc. are likely to be broadcast, and you can watch that channel's broadcast as soon as it starts.
