Description

[Detailed Description of the Invention] [Summary] When a request is made for detailed information on the display side while displaying multiple indexes on a terminal, multiple indexes are displayed on the terminal. To provide an information retrieval method that saves the effort and time of searching by sending a 3A signal to a center based on management information corresponding to display screen information serving as an index, and transmitting selected display screen information to a terminal at the center.

[Field of application of the invention]

The present invention relates to an information retrieval method in which various types of information accumulated in files at a center are selected and transmitted in accordance with a request from a terminal device, and displayed on the terminal device.

The information center 6 searches the image information file 7 for image information according to this request and transmits it to the terminal 1.

The terminal 1 consists of a display section 2, a keyboard 3, and a terminal control section 4. An index, which will be described later, is input from the keyboard 3, and the display section 2 displays selected searches and image information transmitted from the center.

The terminal control section 4 performs transmission control and display control.

In this information retrieval system, it is desired to be able to search for information as simply as possible.

[Conventional technology]

In the conventional method, the index has a tree structure as shown in FIG. 6 to facilitate searching.

That is, for example, the index is divided into large items (A) and CB), and each item is further divided into medium items [A-1].

CA-21, (A-3) and CB-1), (B-2
), CB-3), and the medium items are further divided into small items, and when the search starts, the large items are transmitted from the information center to the terminal and displayed on the display unit.

Here, the information center has each index (1
0), C1ot), [102)..., screen link information [10A], (IOIA).

(102A).

Then, when you select the main item (A) or CB on the terminal, the screen link information 10 will appear on the center.
If major item CA) is selected using A, the screen (10
11, and if the major item (B) is selected, the screen (102
) is read from the information file and sent to the terminal.

On the terminal, these middle items are displayed on the display section for selection.

Then, the information center selects a small item from the screen link information corresponding to the selected medium item and sends it to the terminal.

The above steps are repeated to search for the desired information.

[Problem that the invention seeks to solve]

In the conventional method described above, there is a problem that the search time becomes long because information is transmitted between the information center and the terminal each time each item is selected.

Also, when you want to see the contents of newspapers, magazines, etc., first go to Power! In order to know what kind of contents are listed, an index is looked at, but in the conventional method, when looking at the entire index, data must be sent and received from the center one screen at a time.

Therefore, since the index cannot be viewed continuously, it is difficult to read what is written in a newspaper or magazine at a glance, making it difficult to use the system.

[Means to solve the problem]

For this purpose, the present invention has management information 1[u(CL) for collectively managing a plurality of display image information 11 (Bll to B in) as shown in FIG. 1(A). Furthermore, a plurality of display screen information serving as an index is sent to the terminal together with its management information. The terminal has a function to display multiple index screens sent from the center (for example, [sports news], [general news], CPfxed news] ... [local news]), and users can view the index (heading) of the terminal. You can request detailed information from the center while looking at the screen.

For example, when [Sports News] is selected, a menu screen with detailed information is usually sent from the center.

Furthermore, if one of the [Sports News] Menu 1 screens is selected, for example, "Tennis," news (multiple screens) related to tennis will be sent from the center.

As shown in Figure 1 (B), the screen management information (C1) that manages multiple index screens collectively includes link information to the next information as well as an index screen for searching index screens on the terminal. Contains sending order information.

Here, if the information center and the terminal are connected via a telephone network, the index screen and management information are transmitted all at once from the information center to the terminal, stored on the terminal, and then read out and displayed after the line is disconnected. .

On the other hand, if the information center and the terminal are connected through a dedicated line, the index screen and management information are sequentially and repeatedly transmitted from the information center to the terminal.

[For production]

According to the present invention, since a plurality of 7' screen information and management information are transmitted according to the screen management information and the terminal is selected, there is no need to transmit data to and from the information center at the time of selection. It can save time.

Additionally, the index can be viewed continuously on the screen, making it easier to use.
