Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a screen search method used in videotexts and the like in which screen information such as still images is sequentially displayed on a display screen.

[Conventional technology]

FIG. 3 shows an example of the configuration of a conventionally used videotex system.

In FIG. 3, 41 is a storage device that stores screen information to be displayed on the display screen, and 42 is a central processing unit (hereinafter referred to as CPU) that searches the screen information stored in the storage device 41 and projects predetermined screen information on the display screen. ), 43 is a terminal device that displays the searched screen information on the display screen or makes a selection request for searching the screen information to be displayed.

The screen information here is in the same format as the captain system, including screen management information (A information) such as the screen number that manages the screen information, and information about what screen will be displayed next to the currently displayed screen information. Next screen information for searching (C information), applied service designation information for services such as calculation processing and order entry (E information), display screen information to be displayed on the display screen (B
information).

The C information consists of two types: "comparison data" that is compared with key input data to determine the next screen, and "branch destination screen number" of the next screen that is selected when the key input data matches the comparison data. It is composed of multiple sets of data, each set being one set.

FIG. 4 is a conceptual diagram showing an example of a conventional screen search method in a videotex system that uses the same image information as the captain system.
In FIG. 4, 35, 36, and 37 are search target screens, 31 is the screen number of each screen, 32 is next screen information included in each screen, 33 is comparison data, and 34 is a branch destination screen number.

Next, the operation will be explained. Now, the terminal device 43
, when the user inputs 1# from the terminal device 43 while looking at the screen 135, the next screen 136 is selected by the CPU 42.
The CPU 42 searches the storage device 41 and searches the terminal device 4.
3 to display the next screen 136. Further, if the user inputs the key 2#, the next screen 237 is selected, and the next screen 237 is similarly displayed on the terminal device 43. The same operation is repeated below.

As described above, the screen search method of the conventional videotex system has a tree structure, and the same screen information exists in multiple locations as the next screen at the branch destination.

[Problem that the invention seeks to solve]

The conventional screen search method is configured as described above, so even if the next screen is the same, if the display screen that calls the next screen is different, it is necessary to register multiple images of the same next screen. However, there was a problem in that the capacity of the storage device for storing screen data became large. Furthermore, when a part of the screen is to be corrected, there is a problem in that the same correction must be made for multiple images.

This invention was made in order to solve the above-mentioned problems, and it is possible to search for screens that have the same display screen information as the next screen so that they can be commonly used in several locations by registering one screen. The purpose is to obtain a method.

[Means for solving problems]

The screen search method according to the present invention is based on next screen information attached to a plurality of display screens, and when the next screen is common, the display screen that is the common next screen is designated as the commonly used screen group 13A, and further A mark S indicating that the next screen is in the common use screen group 13A is added to the above next screen information, and a mark S indicating that the next screen is in the common use screen group 13A is added, and
The next screen after displaying the display screen in 3A changes depending on the display screen that called up the common use screen group 13A based on the mark S.

[Operation] In this invention, when the next screen to be displayed next to the screen information attached to the display screen is screen information in the common use screen group 13A, the above-mentioned mark S in the next screen information Common use screen group 1 based on
The screen information in 3A is displayed on the display screen as the next screen.

The next screen after displaying this next screen on the display screen is the common use screen group 13A based on the above mark S.
It changes depending on the screen information that was called.

Therefore, the next screen branches in the same way as in the conventional tree structure without cycling through the branch destinations of the next screen.

[Embodiments of the invention]

An embodiment of the present invention will be described with reference to the drawings. The configuration of the videotex system is the same as the conventional structure.

FIG. 1 is a conceptual diagram of a screen search method to which the present invention is applied. In Figure 1, 11, 12, 1
3, 14, 15, and 16 are the screen numbers of the screens. For ease of viewing, the original 11-digit screen number is shown here as two digits. In addition, 18, 1A, and 1C compare the comparison data in the C information of each screen to 19, 1A, and 1C.
B and 1D indicate the branch destination screen numbers, and 1E indicates the user's key input. In addition, □ in the figure can be any alphanumeric character,
Kana, symbols (JIS C 6220 code 2-5, 11-13
column).

Here, S in comparison data 18, 1A, 1C is a mark indicating that screen information in the commonly used screen group is used as the next screen, and screen number 13
The screen information is screen information in the commonly used screen group 13A used as the next screen branching from the screen information of screen number 11 and the screen information of screen number 15.

FIG. 2 is an example of C information for realizing this method. Reference numeral 21 indicates that when branching from a certain screen, S is written in the comparison data to indicate that the screen is branched as a commonly used screen. Reference numeral 22 is used in the common use screen group 13A, and R is written in the comparison data to indicate that the screen returns to the screen from which the common use screen group 13A was called. In addition, 23 is a common use screen group 13A
N is written in the comparison data to indicate the next branch screen when the screen returns. This is used in conjunction with the 21 mark S mentioned above. In addition, □ in Figure 2 is any alphabet, number, kana, symbol (JIS C
6220 code 2-5, 11-13 columns).

Next, the operation will be explained. Now, for example, when the terminal device 43 displays the screen 0011 and the key is input as 1# from the terminal device 43, the CPU 42 will display the screen 10 as in the conventional search method.
Select 12. Also, when 2# is entered, S is set in the comparison data 18 of screen 0011, so the CPU 42 recognizes the common use screen and follows the branch destination screen number 19 to screen 201.
Select 3 (first step). As a result, when the screen 2013 is displayed on the terminal device 43, when 1# is entered, R (search information) is set in the comparison data 1A, so the CPU 4
2 returns to the screen 0011 where the screen 2013 was previously designated as the common use screen, and selects the screen 3014 according to N (designation information) of the comparison data 18 immediately below.
(Second step). In addition, in FIG. 1, when 3# is keyed in, R is set in comparison data 1A, so the CPU 42 returns to screen 5015 where screen 2013 was previously designated as the common use screen, and displays comparison data 1C immediately below. The screen 6016 is selected according to N (third step).

Furthermore, when screen 5015, which is not included in the same tree structure as screen 0011, is displayed on the terminal device 43, if 1# is entered, the CPU 42 recognizes S in comparison data 1C and displays screen 2013. select. As a result, the screens 20 and 13 appear on the terminal device 43.
When 1# is entered with the key displayed, the CPU 42 displays screen 50 that called up screen 2013.
15, the screen 6016 is selected and displayed on the terminal device 43.

In the above embodiment, S is used to indicate that this is a shared use screen, and R is used to indicate that the screen returns to the original amount screen that was called up.
In addition, the fact that the screen should be selected next via the original screen that was called was indicated by N at the end of the comparison data in the C information, but this is not limited to this. , it is sufficient if the CPU 42 can recognize that it is a mark indicating the use of the common use screen. In addition, in the above embodiment, the mark S is used to remember the screen number of the first screen while the second screen is displayed, but it should be configured so that the previous screen number is always memorized. The mark S is not necessary.

In addition, in the above embodiment, the videotex system was explained as having three elements: a storage device, a CPU, and a terminal device as shown in Fig. 4, but some of these elements may be common, or there may be a need to connect each element. Some communication means may be added and the same effect will be achieved.

〔Effect of the invention〕

As described above, according to the present invention, when the next screen is common based on the next screen information attached to a plurality of display screens, the display screen that is the common next screen is regarded as a commonly used screen group, and further A mark indicating that the next screen is in the common use screen group is added to the above next screen information, and the next screen after displaying the display screen in the common use screen group is the common use screen based on the above mark. Since the group is made to change depending on the display screen that called up the group, if the next screen to be branched has the same screen information, one screen registration can be used in common in several places, and when registering the screen. This leads to savings in screen data capacity, and since only one screen of this commonly used screen group needs to be corrected, there is no need to make the same corrections on multiple screens, resulting in ease of screen maintenance.
