[0040]
The information dividing unit 300 determines the division number (division number P) of the provided data 10 according to the size of the display area (the amount of information that can be displayed), and divides the data into P page data 11.
[0041]
The provided data 10 is data that forms one file provided by the server device 2 and corresponds to, for example, data of one image file. The display area is an area where the provision data 10 is displayed on the terminal device 3 and is the entire screen area of the display unit 35 in the maximum case. This area is allocated to the subpage to be displayed. Therefore, the size of the display area of the provided data 10 is not constant. In the information browsing system 1 in the present embodiment, the size of the display area of the provided data 10 is acquired from an HTML file that specifies the provided data 10. However, you may acquire from the data added to the provision data 10, the system data memorize | stored in the memory | storage part 33, the data obtained from the display part 35, etc.

However, the disk 93 or the memory card 94 may be used as the storage unit 33 or as an auxiliary thereto.
[0051]
The above is the description of the configuration of the terminal device 3 of the information browsing system 1.
[0052]
<1.4 Operation explanation>
The above is description of the structure of the information browsing system 1 in this Embodiment.
[0053]
Next, the operation of the information browsing system 1 in the present embodiment will be described. 6, 7 and 8 are flowcharts showing the operation of the information browsing system 1 in the first embodiment. In the information browsing system 1, first, after various initial settings (not shown) are executed, all the flags F indicating completion of creation of each browsing data 12 are reset to “0” (step S11).
[0054]
Next, the data processing unit 302 receives the user's browsing request signal and determines whether or not a browsing request (HTTP request) has been acquired (step S12). The browsing request is not limited to an input signal from the user. For example, in the HTTP connection in the present embodiment, it is possible to create an HTTP request corresponding to a browsing request by using a script language (for example, JavaScript: trademark of Sun Micro Systems) for the HTML file. When an HTML file is obtained as the provided data 10 (HTTP response), the data processing unit 302 can analyze whether or not a browsing request is further included in the file.
[0055]
If the browsing request has not been acquired (No in step S12), the data processing unit 302 executes a display switching request confirmation process (step S31), a display switching process (steps S32, S33), and the like, and again step S12. The process is repeated after returning to (details will be described later). That is, in the information browsing system 1, by repeating these processes, the information browsing system 1 stands by until there is a browsing request or a display switching request from the user.
[0056]
When the user operates the operation unit 34 to input a browsing request signal, the data processing unit 302 receives the browsing request signal, and a Yes determination is made in step S12. The data processing unit 302 creates the browsing request and gives an instruction to the communication unit 36 to transmit the browsing request to the server device 2. The communication unit 36 transmits a browsing request to the server apparatus 2 based on the instruction, thereby requesting the server apparatus 2 to transmit data indicated by the browsing request (step S13). The request is transmitted to the server device 2 via the network 8 and received by the communication unit 26 of the server device 2.
[0057]
The server device 2 that has received the browsing request transmits the provision data 10 requested by the user by the browsing request to the terminal device 3 (step S14). The processing in step S <b> 14 will be briefly described. The communication unit 26 that has received the browsing request from the terminal device 3 transmits the user's browsing request to the data processing unit 200. The data processing unit 200 transfers the provided data 10 in the storage unit 23 to the RAM 22 based on the browsing request. When the provided data 10 is transferred to the RAM 22, the communication unit 26 transmits the provided data 10 to the terminal device 3 as a response to the browsing request via the network 8.
[0058]
The provision data 10 transmitted from the server device 2 is received by the communication unit 36 of the terminal device 3 (step S15), and the provision data 10 is transferred to the RAM 32. In the information browsing system 1 according to the present embodiment, the process of step S15 is repeated until reception of the provision data 10 is completed.
[0059]
When the reception of the provided data 10 is completed (Yes in step S15), first, the division number P (step S16) indicating the number of page data 11 created from the provided data 10 by the information dividing unit 300 and the order of creation of the page data 11 are set. Determine (step S17). Note that the number of creations and the order of creation of the page data 11 are the same as the number of creations and the creation order of the browsing data 12. The information amount of the page data 11 is determined according to the size of the display area of the provided data 10. Furthermore, the creation order is the order in which normal data is displayed (order from the top), but is not limited to this, and an arbitrary creation order may be separately input.
[0060]
FIG. 9 is a diagram illustrating the relationship between the display area ER1 of the full screen of the display unit 35 and the display area ER2 of the provided data 10. In the HTTP connection, first, when there is a browsing request from a user, an HTML file is transmitted from the server device 2 in an HTTP response. The HTML file includes data related to an image to be displayed in the display area ER1 (generally, data such as a background and a border frame with a subpage). In addition, the script language described above shows data related to the display area ER2 of the subpage (data related to the size and position of the area) and a file (provided data 10) to be displayed on the subpage. In the example shown in FIG. 9, the main page is displayed in the display area ER1, and the display area ER2 for displaying the subpage is defined in a part of the display area ER1. Since the image data for displaying the main page is generally determined based on the display area ER1, it is not an object of information division in the processing described later. Therefore, in the example shown below, a case where a file to be displayed on a subpage is designated as the provision data 10 will be described. Note that the specified information amount of the provided data 10 is a file whose information amount is four times the information amount that can be displayed in the display area ER2, the division number P is “4”, and the browsing data 12a, 12b, 12c, It is determined that the browsing data 12 is created in the order of 12d. These pieces of information correspond to the division attribute information indicating the division state of the provided data 10 and are data constituting the division attribute data 13.
[0061]
Next, the information dividing unit 300 determines data corresponding to the browsing data 12 created from the provided data 10 based on the creation order decided in Step S16 (Step S21), and creates page data 11 (Step S21). S22). In the example shown here, first, data corresponding to the browsing data 12a is selected, and page data 11 that is a conversion source of the browsing data 12a is created.
[0062]
When the page data 11 is created by the information dividing unit 300, the information is transmitted to the browsing information creating unit 301, and the browsing data 12 is created based on the page data 11 (step S23).
[0063]
Next, when the browsing information creation unit 301 finishes creating the browsing data 12, the flag F corresponding to the newly created browsing data 12 is set to “1” (step S24). Next, the selection unit 303 determines whether or not the newly created browsing data 12 is the browsing data 12 first created from the provided data 10 (step S25). Note that the determination in step S25 can be performed, for example, by determining whether there is any other browsing data 12 in which the flag F is set to “1”. And the selection part 303 selects the said browsing data 12a, and displays it on the display part 35, only when the produced browsing data 12 is the first browsing data 12 (browsing data 12a) (step S26). Further, the data processing unit 302 displays a switching button corresponding to the newly created browsing data 12 based on the division attribute data 13 (step S27).
[0064]
That is, in the information browsing system 1, only the browsing data 12 (12a) created first is displayed on the display unit 35, and the browsing data 12 other than the first browsing data 12 is not displayed at the time of creation. . However, a switching button corresponding to the created browsing data 12 is displayed on the display unit 35 by the data processing unit 302.
[0065]
FIG. 10 is a diagram showing the relationship between the browsing data 12 displayed in the display area ER2 and the switching buttons IF1 to IF4. In FIG. 10, the browsing data 12a to 12d are shown in a partially overlapped state. However, since these data are actually displayed in the same display area ER2, only one of the browsing information 12 is displayed. Cannot be viewed (hidden). Further, the switching buttons IF1 to IF4 displayed by the data processing unit 302 are always displayed in the display area ER1. Each switching data IF is associated with each switching button IF as indicated by an arrow, and when the user selects one of the switching buttons IF1 to IF4 by operating the operation unit 34 in the process described later, The browsing data 12 associated with the selected switching button IF is displayed. At this time, the browsing data 12 displayed so far cannot be browsed.
[0066]
Thus, in the information browsing system 1, since each switching data 12 is created, the switching button (dividing information) is sequentially displayed based on the dividing attribute data 13, so that the user has a plurality of provided data 10 ( (Indicated by the number of switching buttons to be displayed) and the currently selectable browsing data 12 (browsing data that has been created) can also be recognized. is there. Thereby, it is possible to prevent the user from making an erroneous display switching request such as designating browsing data 12 that has not yet been created.
[0067]
11, 12, and 13 are conceptual diagrams illustrating timings when browsing the browsing data 12. The example shown in FIG. 11 is a case where one browsing data 12 is displayed in the display area ER2 in the conventional system. The example shown in FIG. 12 is a case where a plurality of browsing data 12 are displayed using tabs in a conventional system. Moreover, the example shown in FIG. 13 is a case where each browsing data 12 is displayed on display area ER2 by the information browsing system 1. FIG. In order to simplify the comparison, the loading time (conversion time) of each browsing data 12 indicated by the wavy line is the same, and the browsing time of the user for each browsing data 12 indicated by the solid line is also indicated as the same. . Further, in the case shown in FIG. 11, only one piece of browsing data 12 is created and information of a portion that cannot be displayed simultaneously by scrolling is displayed, but is divided into four for comparison.
[0068]
In the example shown in FIG. 11, only one browsing data 12 is created, and the user cannot start browsing until all the data of the provided data 10 is converted. Since the data 12 is created, the switching response time hardly occurs.
[0069]
In the example shown in FIG. 12, although the display response time until the first browsing data 12a is displayed is improved, each time the browsing of the browsing data 12a is finished and the display is switched by the user, Since the browsing data 12 specified in the tab is loaded (created), a switching response time occurs every time the user switches the display. Therefore, the browsing for the last browsing data 12d is the same as the example shown in FIG.
[0070]
Here, as in the example shown in FIG. 13, in the case of the information browsing system 1, a display response time is generated while the browsing data 12 a is created, so the time until the browsing data 12 a is displayed is This is the same as the example shown in FIG. However, since the browsing data 12b, c, and d are sequentially created while the user is browsing the browsing data 12a, the display switching response time hardly occurs.
[0071]
That is, in the information browsing system 1, the provided data 10 is divided according to the display area ER2, and the browsing data 12a for one screen of the display area ER2 is first created and displayed, thereby making it possible to compare with the example shown in FIG. Thus, the response time until the user starts browsing is shortened. Furthermore, while browsing the browsing data 12 displayed previously by the user, the browsing data 12b, c, d to be browsed next is created in sequence, so that the display is made in comparison with the example shown in FIG. It is possible to shorten the response time until the is switched. Therefore, the information browsing system 1 can shorten the time until browsing of the browsing data 12d is completed as compared with the conventional system.
[0072]
As is apparent from FIGS. 11 to 13, the display response time shortened by the information browsing system 1 is longer as the data load time is longer. That is, when the information browsing system 1 handles data with a large amount of information such as an HTML file that constitutes a Web page as the provided data 10, the response time can be further shortened as compared with the conventional system.
[0073]
Next, when the switching button IF is displayed, it is determined whether a display switching request has been acquired (step S31). When the display switching request signal is not input by the user, the processes of steps S32 and S33 are skipped.
[0074]
On the other hand, when the display switching request signal is input, first, the selection unit 303 selects the browsing data 12 to be displayed from among the plurality of browsing data 12 according to the display switching request signal (step S32). The selected browsing data 12 is displayed in the display area ER2 of the display unit 35 (step S33).
[0075]
Thus, the browsing data 12 according to a user's request | requirement can be displayed by the selection part 303 selecting the browsing data 12 displayed on the display area ER2 based on the display switching request | requirement from a user.
[0076]
Next, the value of the flag F is confirmed (step S34), and it is determined whether or not all browsing data 12 has been created (step S35). If there is browsing data 12 that has not yet been created, the step is performed. Returning to S21, the process of creating browsing data 12 is further repeated.
[0077]
On the other hand, if all the browsing data 12 has been created, the data processing unit 302 acquires the browsing request (further request) by analyzing the provided data 10 received in step S15, and returns to step S12 for processing. repeat. That is, when a file to be displayed is specified in the provided data 10, the process is repeated with the file as the next provided data 10.
[0078]
As described above, the information browsing system 1 according to the present embodiment is similar to the conventional system when the provision data 10 having a larger amount of information than the amount of information that can be displayed in the designated display area ER2 is selected. In addition, the browsing data 12 is displayed in the display area ER2 when the browsing data 12 corresponding to the display area ER2 is created without waiting until all the data of the provided data 10 is converted (loaded). As a result, the display response time can be shortened.
[0079]
In addition, the information browsing system 1 creates and displays a switching button IF corresponding to the created browsing data 12, and a display switching request is made by the user via the switching button IF. Therefore, since the selection unit 303 selects the browsing data 12 to be displayed from the browsing data 12 existing in the terminal device 3, unlike the display switching method using the tab in the conventional system, the communication unit and the communication process are performed according to the display switching request. The display response time can be further shortened without causing data conversion processing.
[0080]
In addition, since the information browsing system 1 provides Web information such as an HTML file using an HTTP connection, by implementing a mechanism for sequentially loading pages into the HTML file using a script language, for example, information division Functions of the unit 300, the browsing information creation unit 301, the data processing unit 302, and the like can be easily realized.
[0081]
In the information browsing system 1 according to the present embodiment, it has been described that the creation of the page data 11 is not started until all the provision data 10 is received in step S15 illustrated in FIG. The creation of the page data 11 by the information dividing unit 300 may be started. In that case, since the first page data 11 is created when the reception of the data included in the browsing data 12a is completed, the display response time is further increased as compared with the case where the reception of the provided data 10 is completed. It can be shortened.
[0082]
When the user browses data, the browsing time is usually longer than the data loading time. Therefore, the browsing data 12 (browsing data 12a) displayed at least first by the information browsing system 1 is created according to the size of the display area ER1, and the remaining data is converted into one browsing data 12. You may make it do. Even in this case, the display response time can be shortened if the remaining browsing data 12 is created while the user is browsing the browsing data 12 displayed first.
[0083]
<2. Second Embodiment>
In the first embodiment, the information dividing unit 300 that divides the provided data 10 is provided in the terminal device 3 so that the browsing data 12 is created while the provided data 10 is divided in the terminal device 3. . However, the function of the information dividing unit 300 can be provided on the server device 2 side. That is, the server device 2 may be configured to divide the provided data 10 into a plurality of page data 11 and sequentially transmit the divided page data to the terminal device 3 to create and display the browsing data 12. .
[0084]
FIG. 14 is a diagram illustrating a functional configuration realized by the CPU 20 in the server device 2 of the information browsing system 1 according to the second embodiment configured based on such a principle. In addition, about the structure similar to the information browsing system 1 in 1st Embodiment among the structures in the information browsing system 1 in 2nd Embodiment, while attaching | subjecting the same code | symbol, description is abbreviate | omitted suitably.
[0085]
The information dividing unit 201 illustrated in FIG. 14 is a function realized by the CPU 20 operating based on the program 210 in the ROM 21. The information dividing unit 201 has a function of dividing the provided data 10 into a plurality of page data 11 according to the size of the display area ER2 on which the provided data 10 is displayed. Although details will be described later, in the actual operation, as shown in FIG. 14, not all the page data 11 is created at once, and is necessary according to one browsing request (request) from the terminal device 3. One page data 11 is specified, and corresponding data is extracted from the provided data 10 and created. Each page data 11 is transmitted from the communication unit 26 to the terminal device 3 as data constituting one response.
[0086]
Further, when creating each page data 11, the information division unit 201 creates division attribute data 13 (information such as the number of the created page data 11) that is information related to the division state of the provided data 10 and stores it in the RAM 22. Forward. The division attribute data 13 is transmitted to the terminal device 3 by the communication unit 26 as one response together with the page data 11.
[0087]
FIG. 15 is a diagram illustrating a functional configuration realized by the CPU 30 in the terminal device 3 of the information browsing system 1 according to the second embodiment. In the terminal device 3 in the present embodiment, the page data 11 is sequentially received by a plurality of communications with the server device 2, and the browsing data creation unit 301 generates browsing data 12 each time. In FIG. 15, signal lines are not shown, but each page data 11 is referenced and analyzed by the data processing unit 302.
[0088]
Next, operation | movement of the information browsing system 1 in 2nd Embodiment is demonstrated. FIGS. 16, 17 and 18 are flowcharts showing the operation of the information browsing system 1 according to the second embodiment. In addition, also about operation | movement, description is abbreviate | omitted suitably about the process similar to 1st Embodiment.
[0089]
First, the standby state until acquiring the browsing request and the display switching request is the same as in the first embodiment.
[0090]
When a browsing request signal is input by the user, a Yes determination is made in step S42, and a browsing request designating the corresponding provided data 10 is created by the data processing unit 302 and transmitted to the server device 2 by the communication unit 36. A request is made (step S43). The communication unit 26 of the server device 2 transfers the received browsing request to the data processing unit 200.
[0091]
The data processing unit 200 analyzes the browsing request, specifies the provision data 10 indicated in the browsing request, and transfers it to the RAM 22 (step S44). The information dividing unit 201 determines the division number P according to the size of the display area ER2 on which the provided data 10 is displayed, and also determines the generation order of the page data 11 and generates the division attribute data 13 (steps S45 and S46). ). Further, the provided data 10 is divided into page data 11 according to the determined creation order (step S47). As described above, in step S47, the information dividing unit 201 does not create all the page data 11 (for example, page data 11a, b, c, d), but first creates only the page data 11a. At the same time, information (number) indicating that the transmitted page data 11 is the page data 11 a is included in the divided attribute data 13. Then, the communication unit 26 transmits the division attribute data 13 and the page data 11 indicated by the division attribute data 13 as a response to the terminal device 3 (step S48).
[0092]
When the page data 11 (response) is received by the communication unit 36 of the terminal device 3 (Yes in step S51), the browsing information creation unit 301 creates the browsing data 12 (step S52).
[0093]
Further, each time the browsing data 12 is newly created, the browsing data 12 and the switching button IF are displayed in the display area ER2 of the display unit 35 by executing the same processing as in steps S24 to S27 in the first embodiment. Is displayed (steps S53 to S56).
[0094]
As a result, the information browsing system 1 in the second embodiment does not wait for all the data of the provided data 10 to be converted into the browsing data 12, and the browsing data 12 a created first on the display unit 35. Since it can display, the display response time with respect to a user can be shortened.
[0095]
Next, as in steps S31 to S33 in the first embodiment, confirmation of a display switching request (step S61) and display switching processing (steps S62 and S63) are executed.
[0096]
Further, the value of the flag F is confirmed (step S64), and it is determined whether all the browsing data 12 has been created (step S65). If there is browsing data 12 that has not yet been created, the processing from step S42 is repeated so that the data processing unit 302 transmits the page data 11 corresponding to the browsing data 12. In this case, a Yes determination is made in step S42, and a request for page data 11 is transmitted.
[0097]
In this way, the information browsing system 1 in the second embodiment receives the page data 11 and creates the next page data for the server device 2 each time the browsing data 12 is created based on the page data. In the information browsing system 1, the server device 2 needs to maintain communication with the terminal device 3 until all the page data 11 is transmitted. Absent.
[0098]
On the other hand, when all the data of the provided data 10 is converted and all the browsing data 12 is created (Yes in step S65), a file is further required to display the provided data 10 by the data processing unit 302. Whether or not there is an analysis is performed, and only when there is a necessary file, a browse request for requesting the file is created, and the processing from step S41 is repeated.
[0099]
As described above, also in the information browsing system 1 in the second embodiment, the browsing data 12a can be displayed before the data of the provision data 10 requested to be browsed by the user is converted. The effect similar to the information browsing system 1 in 1 embodiment can be acquired.
[0100]
Further, in response to a browsing request made by the terminal device 3 with respect to each page data 11, the server device 2 performs communication for each page data 11 obtained by dividing the provided data 10, thereby transmitting / receiving data data at a time. The amount can be reduced. Thereby, it is possible to improve the transmission efficiency when a communication error occurs.
[0101]
  In addition, when the data processing unit 302 loads the next page data 11 each time loading of each page data 11 is completed, and the loading fails (when the next page data cannot be loaded), retransmission is performed. Communication vulnerability, such as requestingsexCan be supplemented.
[0102]
In addition, by ordering a plurality of data to be transmitted and causing the data processing unit 302 to transmit each page data 11 according to the order, it is detected that all data has been successfully received in asynchronous data communication. can do.
[0103]
In addition, since the information browsing system 1 provides Web information such as an HTML file using an HTTP connection, by implementing a mechanism for sequentially loading pages into the HTML file using a script language, for example, information division Functions of the unit 300, the browsing information creation unit 301, the data processing unit 302, and the like can be easily realized.
[0104]
<3. Modification>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made.
[0105]
For example, the method of displaying the division information on the display unit 35 is not limited to displaying the switching button IF. The division information may be displayed by displaying a dummy page corresponding to the newly created browsing data 12 when the browsing data 12 for the second time or later is created. FIG. 21 is a diagram showing an example of displaying the browsing data 12 based on such a principle. First, when the browsing data 12a is first created, the browsing data 12a is displayed in the display area ER2 in a state that the user can browse (active), and when the subsequent browsing data 12 is created, the user cannot browse. The dummy page is displayed so as to be slightly shifted from the display area ER2 (FIG. 21A). Here, when the user operates the mouse 341, for example, when an area where the dummy page of the browsing data 12b is displayed is displayed, the selected browsing data 12b is brought to the front as shown in FIG. The browsing data 12a that has been displayed in a pop-up and is active may be displayed as a dummy page.
[0106]
In addition, the browsing data 12a to be displayed first is the size of the display area ER2 in that the amount of information that can be browsed first is maximum and information that cannot be displayed simultaneously in the display area is not converted. However, the present invention is not limited to this, and the division number P may be set in advance.
[0107]
The display switching request for the browsing data 12 is not limited to that input from the user. For example, the information browsing system is configured to automatically switch character information such as “lyrics” displayed in the display area of the display unit 35 in accordance with the reproduction speed of the sound while outputting the sound by a music file. 1 may be automatically selected according to various conditions.
[0108]
Moreover, the process which the information browsing system 1 performs is not limited to the process shown in the said embodiment, A required process may be performed suitably. Further, the order in which the processes are executed is not limited to the above embodiment, and the processes may be executed in any order as long as substantially the same effect can be obtained.
[0109]
The functions of the data processing units 200 and 302, the information division units 201 and 300, the browsing information creation unit 301, the selection unit 303, and the like are realized by software as the CPUs 20 and 30 operate according to the programs 210 and 310. However, some or all of these functions may be realized by hardware using a dedicated electronic circuit.
[0110]
In the above embodiment, every time new browsing data 12 is created, the switching button IF corresponding to the browsing data 12 is displayed. However, the number of divisions P of the provided data 10 is determined by the information dividing units 201 and 300. These switching buttons IF may be displayed in advance when determined. In that case, since the user can grasp in advance that the provided data 10 is divided into a plurality of browsing data 12, the user mistakenly recognizes that the browsing of the providing data 10 has ended just by browsing the first browsing data 12. This can be prevented.
[0111]
【The invention's effect】
  Claim 1,6 and 11In the invention described in the above, the display response time when the user browses the provided information can be shortened by displaying the selected browsing information while the plurality of browsing information is sequentially created. .
[0112]
  Claim 2And claim 7In the invention described in (1), the display response time can be shortened most by selecting the browsing information created first.
[0113]
  Claim 3And claim 8In the invention described in the above, by displaying the division information together with the selected browsing information based on the division attribute information, the user can easily grasp the division state (the number of browsing information, etc.) of the desired provided information Can do.
[0114]
  Claim 4And claim 9In the invention described in the above, the browsing information according to the user's request can be displayed by selecting the browsing information to be displayed in the display area in response to the switching request signal.
