Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is a video system that receives, processes, and displays various information stored in files in an information center and selectively transmitted in accordance with requests from terminals. Tex terminal device.

An information retrieval system has been proposed in which various types of information stored in files at a conventional technical information center are selected and transmitted in accordance with a request from a terminal, processed by the terminal, and displayed on a display unit. As shown in FIG. 6, this sends a request from the keypad 3 of the terminal 1 to the captain information center 6 via the interface 15. Modem 129 line connection section 11
．． The information is transmitted via the Videotex circuit network 6, and the information center 〇 searches for image information from the image information file 7 according to this request and transmits it to the terminal 1. On terminal 1, image information is transferred to modem 1.
2 demodulates and receives it, and sends it to a microcomputer (CPU) 19 and display control unit 1 via an interface 15e.
6, the signal is loaded into the video RAM 17 for processing, and further passed through the D/A converter 18, converted into an analog signal, and displayed on the display unit 2, which is made up of a cathode ray tube or the like.0Here, 4 is the telephone, and 13 is the This is a RAM used as a work area necessary for control by the CPU 19, and 14
is a program ROM.

Problems to be Solved by the Invention In the conventional search method described above, each time there is image information to be searched, the key bat 3 is operated to obtain the desired image information. There was a problem in that when searching slowly, the communication channel was monopolized during that time, making it impossible to use the telephone.

In addition, when a terminal is installed on the street and a service is provided to an unspecified number of people by collecting a fee, the display only shows a still image when the user is not using it. Therefore, there was a problem that the appeal to users was weak. The present invention provides a Videotex terminal device.

Means for Solving the Problems The present invention comprises a memory for storing index numbers of a plurality of image information to be searched, and an image memory for storing the image information to be searched, and an index stored in the memory in advance. Based on the number, image information is automatically selected and transmitted, stored in the image memory, and then the communication path is completely cut off, while the image information is sequentially recalled from the image memory and displayed repeatedly on the display unit. .

According to the present invention, the index number of the image information to be searched is stored in the memory in advance, image information is automatically called up from the center based on this index number, and after the image information is stored in the image memory, communication is performed. By disconnecting the communication line (communication line), congestion of the communication line can be prevented, and image information can be searched slowly.

Example.

An example of this will be described below with reference to FIGS. 1 to 6. FIG. 1 shows a block diagram of an embodiment of the present invention, FIG. 2 shows an example of display of image information, and FIGS. 3 to 5 show display states when inputting various data.

In FIG. 1, 2o is an image memory that stores image information corresponding to the index number transmitted from the information center 6.0 In addition, in the Gagaru device, there are multiple indexes to be searched by the key bat 3. number in RAM1s
I try to remember it. The other configurations are the same as in FIG. 6.

This terminal device 1 is basically the same as the one in FIG.
The key bat 3 transmits the request (index number) to the captain information center 6 via the Lahiteotex circuit network 5, and the captain information center 6 searches for image information from the image information file 7 according to this request and sends it to the terminal device 1. I'm trying to send it. In addition, by inputting an index number to be described later from the key bat 3, storing it in the RAM 13, and starting a program stored in the ROM 14, image information is automatically read out from the captain information center 6 based on the index number. It is transmitted toward the terminal device 1. This image information is written and stored in the image memory 20. Then, the terminal device 1 is disconnected from the Videotex circuit network 5 by the line connection section 11, and the terminal device 1 is connected to the telephone set 4. On the other hand, the CPU 19 repeatedly reads image information from the image memo 1J20 and displays it in the display control unit 1.
6 and a video RAM 17, and converted into an analog signal by a D/A converter 18, the signal is displayed on a display section 2 comprising a cathode ray tube or the like. FIG. 2 shows the display state of this image information.

According to this configuration, image information is automatically read out from the captain information center 6 based on the index number stored in the RAM 13 and stored in the image memory 2o.
At step 1, the terminal device 1 is disconnected from the Videotex circuit network 6 and connected to the telephone 4, while the image information stored in the image memory 20 is repeatedly read out and displayed on the display section 2, thereby reducing the exclusive use time of the communication channel. This allows you to search for image information slowly.

In this embodiment, a mode in which image information is written to the image memory 21, read out, and displayed repeatedly, and a mode in which image information to be searched is requested and displayed one by one can be selected by key operation on the keypad 3. I have to.

In addition, in this example, considering that the image information can be changed at the Ki4buten information center 6, in addition to setting the continuation period with the Videotex circuit network 6 to, for example, 1 hour, the image information (index number) is registered. Different index numbers can be written in modes iA and B. For example, in the first hour, image information based on the index number of field registration A is called up, and in the next period 1
At time, image information based on the index number of the screen entry B is called up, updated and written into the image memory 20, and read out. Figure 2A shows the image information corresponding to the index number registered in screen registration A, and Figure 2B shows the image information corresponding to the index number registered in screen registration B. shows. For example, sports news.

Information such as general news, economic news, and local news is displayed repeatedly one after another.

Figures 3 and 4 show examples of display when index numbers are written and bound. For example, with key bat 3, r*12
3991 J and the index number can be input and written to the RAM 13.

Figure 5 is an example of the screen when setting the line connection cycle and playback display interval.
It is possible to connect the Videotex network 5 and the terminal device 1, and image information can be reproduced and displayed at intervals of 2 seconds. This information is also stored in the RAM 13. Effects of the Invention As described above, according to the present invention, the index number of the image information to be searched is stored in advance in the memory within the terminal, and the image information is automatically retrieved from the terminal. By calling and storing this image information in the image memory, the communication line can be subsequently disconnected, thereby preventing congestion of the communication line and allowing the image information to be retrieved slowly. Another advantage is that because the images are constantly moving, it has a strong appeal to users and viewers as a terminal installed on the street.
