Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a videotex terminal system,
In particular, the present invention relates to a terminal system having a function of storing information received from a video text center.

(b) Technical background Videotex is an internationally recognized name for image information services, and Japan's public services that fall under this category are called captains. or,
The Videotex method is also being adopted as a private information service method by a company or a group of companies.
Furthermore, connections between them and public services are also being considered.

(c) Prior art and problems Companies that have terminal devices that use an external videotex center generally use the terminal devices 1, 2, etc. as the company's private telephone exchange, etc., as shown in Figure 1. The terminal equipment is accommodated in a switchboard (PBX) 3 and connected to the videotex center via a central office line 4 and the PBX 3, thereby configuring a videotex terminal system. Note that 9 represents a normal telephone that uses the same exchange.

Conventionally, in such systems, when the same image or game service is repeatedly received by the same or different terminal devices, the services received from the video techs center in such systems are always connected to the video techs center and the service is requested again each time. I needed to.

(d) Purpose of the Invention The purpose of the present invention is that when receiving the same service repeatedly as described above, the information from the previous service can be retained and the information can be accessed from time to time without reconnecting to the videotex center. The object of the present invention is to provide a videotex terminal system having means for making services available.

(e) Structure of the invention The purpose is to provide an exchange, a terminal device, a control device,
and a data storage device, the exchange has a path connecting to the videotex center, receives a predetermined connection request, configures the connection between the path, the terminal device, and the control device, and configures the connection between the path, the terminal device, and the control device. The control device, when the terminal device connects to the control device via the exchange and receives predetermined request information from the terminal device,
A request is made to the exchange to connect to the videotex center, configure a connection path between the terminal device and the videotex center within the control device, and transmit data that the terminal device receives from the videotex center. is intercepted on the connection path, stored in the data storage device with the name specified by the request information, and the terminal device connects to the control device via the exchange, and the terminal device When a search request is received,
This is achieved by the videotex terminal system of the present invention, which is configured to search the data storage device for data with the name specified in the search request and transmit it to the terminal device.

That is, when a terminal device and an external videotex center are connected and service is received from the center, a data storage device is connected to this connection path within the PBX, and information received from the videotex center is stored in the storage device. The information can be read out from the data storage device and used later.

(f) Embodiment of the invention FIG. 2 is a system configuration diagram of an embodiment of the invention. In the figure, the terminal devices 1, 2, PBX 3, etc. are the same as in FIG. 1. In the present invention, a data storage device 6 is connected to the PBX 3 via a control device 5.

The data storage device 6 can be constituted by, for example, a magnetic disk device commonly used in electronic computer systems.

The control device 5 receives information from the PBX 3 side,
This is stored in the data storage device 6. In addition, the information stored in the data storage device 6 is managed as a database, and the information requested from the terminal devices 1, 2, etc.
Searching from the database of the data storage device 6,
Has the ability to send to the requester. Other features include
This will become clear from the explanation that follows.

In order to perform these processes, the control device 5 can be configured by, for example, a small computer system.

In this embodiment, for example, when the terminal device 1 receives a service from a videotex center, if you want to save the information received from the service, you can save the information received by the service by dialing a specific telephone number.
3, the connection 1 between the terminal device 1 and the control device 5
0 is configured.

In this state, the terminal device 1 sends a dial signal to the control device 5 to designate connection with the video techs center and storage of information, and designate the name of the stored information. This name is used to identify the stored information when the information is used later, and may be a number, for example.

When the control device 5 receives the above designation, the PBX3
A call is made to the station, the dial number to be connected to the central office line 4 and the number of the videotex center are sent, and a connection with the videotex center is established via the connection path 11 shown in the figure.

When the above connection is configured, as conceptually shown by the broken line in the control device 5, the terminal device 1 and the videotex center are connected directly or relayed within the control device 5, and signals can be freely exchanged. Also, the control device 5
can intercept that signal.

In this state, the terminal device 1 starts the service at the videotex center by sending out a dial signal specifying the service in the same way as when receiving a videotex service in the normal way, and various image information , game program information, etc. are sent to the terminal device 1 via the central office line 4, PBX 3, and control device 5. The terminal device 1 receives and processes this service in a normal manner.

During this time, the control device 5 intercepts the above information sent from the video text center and stores it in the data storage device 6.

When the service ends and the terminal device 1 disconnects through normal operation, the control device 5 detects this and disconnects from the central office line 4. The information received so far and stored in the data storage device 6 is given a name specified by the terminal device 1 at the beginning of this service, and is registered in the database.

In the venue where the stored information is used, the terminal device 1 or 2 etc. is connected to the control device 5 in the same manner as described above,
The search service designation and the name of the information are designated by the dial signal.

When the control device 5 receives this designation information, it searches the data storage device 6 for information on the designated name, reads it out, and transmits it to the requesting terminal device.

It is possible for the terminal devices 1, 2, etc. to receive services from the videotex center in the usual manner by dialing the number of the central office line 4 directly.
In that case, since the service information does not go through the control device 5, the service information is naturally not stored in the data storage device 6.

The functions that can be used to search, edit, delete, etc. the information stored in the data storage device 6, the management of the qualifications for using these functions, etc., depend on the functions of the database management system executed by the control device 5. However, various applications are possible within the scope of the present invention.

(g) Effects of the Invention As is clear from the above description, according to the present invention, information provided from the videotex center and used repeatedly is transmitted between the terminal device and the videotex center while communicating in the usual manner. The accumulated information can be used from any terminal device without connecting to the videotex center, which has a significant industrial effect of improving the speed and economy of this type of service. be.
