Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a videotex image retrieval system in, for example, a CAPTAIN center (Character Graphic Information Network Center).

[Conventional technology]

FIG. 4 is a block diagram showing a conventional Videotex image retrieval system. As shown in FIG. 4, the Videotex image retrieval system consists of a center device 50 that provides image data and a terminal device 26 that displays the image data.

Also, inside the center device 50, an image data storage section 51. A readout unit 52 that reads out data in the storage unit 51.
A determining unit 53 that determines the most suitable data among the data read out by the reading unit 52. A transfer unit 25 is provided to send the determined data to the terminal device 26. Note that the arrows in the figure indicate the flow of data.

FIG. 5 is a diagram showing data in the storage unit in the center device in the Videotex image retrieval system of FIG. 4.

As shown in the figure, display data 62.1 for one screen number 61. There are two pieces of data, back data 63.

FIG. 6 is a diagram showing the flow of processing when selecting optimal data for a certain screen number in the center device in the Videotex image retrieval system of FIG. 4.

Next, the operation of the conventional Videotex image retrieval system will be described. Now, assume that an appropriate amount of data is determined for a certain screen number 1, and the data is sent to the terminal device 26. One screen number has two pieces of data, front and back, as shown in FIG. For this reason, first, in each processing step 41 and 42 shown in FIG. 6, the above two data are read out from the storage section 51 by the reading section 52. Each piece of data includes a designation as to when the data will be provided. The optimal data referred to here is the data for which the start time of the provision period is specified later.

Therefore, next, in the processing step 431, the provision periods of the two data read out by the determination unit 53 are compared. If the front data 62 is slower, the front data 62 is selected in the processing step 44, and if the back data 63 is slower, the back data 63 is selected in the processing step 45. do. The data determined so far is transferred to the processing step 461 by the trowel transfer unit 25.
The data is then transferred to the terminal device 26, and the terminal device 26 then displays this data.

[Problem that the invention seeks to solve]

The conventional Videotex image retrieval system described above is configured as described above, so it is very confusing because two different types of data are actually assigned to the screen number, which is only one identification code. Unfortunately, when modifying or updating data, there are problems such as modifying or updating different data.

The present invention was made to solve this problem, and an object of the present invention is to provide a videotex image retrieval system that can reliably identify data.

[Means for solving problems]

The Videotex image retrieval system according to the present invention includes:
Only one data corresponds to one screen number,
Several screen numbers can be defined as a set, and the most suitable one can be selected from a plurality of data.

[Effect]

In the Videotex image retrieval system of the present invention, only one data corresponds to one screen number, and from a plurality of data corresponding to several screen numbers defined as a set, conventional front/back Compare the data in the same way as the data and select the most suitable one.

〔Example〕

FIG. 1 is a block diagram showing a Videotex image retrieval system which is an embodiment of the present invention. As shown in FIG. 1, the Videotex image search system is comprised of a center device ff20 that provides image data and a terminal device 26 that displays the image data. Also, inside the center device 20, there is a bond storage unit 21 for one-item data. A reading section 22 that reads out data in the storage section 21. A determining unit 239 that determines the optimal data read out by the reading unit 22 is referred to by the determining unit 23i, and a rule 24 that defines a set of screen numbers. A transmission unit 25 is provided to send the determined data to the terminal device 26. Note that the arrows in the figure indicate the flow of data.

Figures 2 (al and b) are diagrams showing data and composition agents in the storage section in the center mount in the Videotex image retrieval system I of Figure 1, respectively.The screen shown in Figure 2 f &) The data corresponding to number 31 is 32. Further, in this example of the composition 24 shown in FIG. 2(b), the screen number paired with the screen number 31 is 34, and the screen number 33 is the same as the screen number 31.
The screen number of this pair is 35.

FIG. 3 is a diagram showing the flow of processing when selecting optimal data for a certain screen number in the center device in the Videotex image search system of FIG. 1.

Next, the operation of the Videotex image retrieval system which is an embodiment of the present invention will be described.

First, in a processing step 11 shown in FIG. 3, the determination unit 23 refers to the composition 24 and determines the screen number to be a set.

For example, r 1234567 as shown in screen number 31
For the screen number 8900j, a 111ili surface number r12345678950J shown in screen number 34 is determined. Next, in processing step 12, the reading section 22 reads out data corresponding to the first specified lj screen number from the storage section 21.

Furthermore, in the processing step 13, the reading unit 22 similarly reads out the data corresponding to the screen numbers determined as a set from the storage unit 21.Next, in the processing step 14, the determining unit 23 The two read data are compared.As with the conventional method described above, the comparison here is assumed to be for specifying the start time of the provision period later than the later one.

If the data corresponding to the initially specified screen number is different, the screen number is selected in processing step 15f, and if the data corresponding to the set is slower, in processing step 16 Select the screen number determined as a group.

The data determined in this way is transmitted to the terminal device 26 by the transfer unit 25 in a processing step 17, and then the terminal device 26 displays this data.

In the above embodiment, the configuration of the Videotex image search system was explained as shown in the block configuration diagram shown in FIG. , there may be 10 additional functions, or some of these may be combined or separated (or each may be connected by some communication means).

In the above example, in the set rule 24, if the second digit from the bottom is 0 to 4, add 5, and if 5 to 9, add 5.
It shows the rules for drawing, but is not limited to this. Further, in this example, the set of screen numbers is two screens, but depending on the set rules, the set may be made up of any number of screens.

Further, in the above embodiment, the start time of the provision period is used to select the optimal data, but the present invention is not limited to this.

〔Effect of the invention〕

As explained above, in the Videotex image retrieval system, this invention allows only one data to correspond to one screen number t, and allows several screen numbers to be defined as a set. Since the most suitable one can be selected from the list, this has the excellent effect of ensuring data identification and maintenance.
