Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a data distribution method for a terminal device to retrieve target data from a plurality of data stored in a server and to download the retrieved data from the server to the terminal device.
[0002]
[Prior art]
In recent years, data distribution services via communication networks such as the Internet have become widespread. A user of a data distribution service (hereinafter referred to as “user”) uses a communication terminal to provide a server of a provider (hereinafter referred to as “CP (Content Provider)”) that provides the data distribution service via a communication network. And download the desired data stored in the server to the communication terminal.
[0003]
When a user downloads a lot of data to the communication terminal, the user feels difficulty in finding data to be used from the downloaded lot of data. In order to eliminate such inconvenience, there is a method in which the CP creates index data for every distributable data, and the user downloads and uses the index data. According to this method, when the user wants to search for target data from a large number of downloaded data, the user can obtain information on the target data from the index data by inputting a search keyword to the communication terminal. it can. As a result, the user can easily find the target data.
[0004]
However, since the data that can be distributed by the CP changes every day, when the user downloads data that can be newly distributed to the communication terminal, the information of the newly downloaded data is registered in the old index data. The inconvenience that there is no occurs. Furthermore, information already registered in the index data may become outdated, and the search result desired by the user may not be obtained.
[0005]
For such a problem, every time the communication terminal connects to the CP server via the communication network, the data for the communication terminal to update the latest index data or index data from the CP server according to the server instruction Is known, and the index data is always kept up-to-date (for example, see Patent Document 1). This technique is referred to as the first conventional technique for convenience.
[0006]
[Patent Document 1]
Japanese Patent Laid-Open No. 10-187169
[0007]
On the other hand, services that lend application programs (hereinafter referred to as “applications”) via communication networks such as the Internet have become widespread. For example, a user temporarily downloads an application from a server of an application lender (hereinafter referred to as “ASP (Application Service Provider)”) to a communication terminal via the Internet and uses the application.
[0008]
An application downloaded from an ASP to a communication terminal is usually written in a markup language such as XML (Extensible Markup Language) and is executed in browser software. In that case, various data constituting the application, that is, data used by the browser software is not continuously stored in the HD (Hard Disk) of the communication terminal, but is downloaded from the ASP server to the communication terminal as necessary. It will be discarded when use by browser software is completed.
[0009]
The application lending service as described above can be used from any communication terminal that can connect to the Internet and execute browser software. Therefore, the user can receive the same service from the destination communication terminal without requiring an application installation operation or the like.
[0010]
Furthermore, the application lending service as described above is particularly effective in the use of an application that handles a large-scale database or the like. This is because, when using the application lending service, the user does not need to obtain the entire database, but can obtain only the necessary results by simply transmitting the search condition to the ASP server. Further, when it becomes necessary to update the contents of the database, the ASP only needs to update the database stored in the server. This technique is referred to as the second prior art for convenience.
[0011]
[Problems to be solved by the invention]
By the way, according to the first prior art, when the size of the index data or the data for updating the index data is large, it takes time and expense to download the data, which is inconvenient for the user. However, if the data size is reduced by reducing the number of items of information registered in the index data, a desired search result cannot be obtained when the user performs a search using the index data. On the other hand, if only the information related to the data already downloaded to the communication terminal is registered in the index data, the size of the index data is reduced, but the information about the data that has not yet been downloaded to the communication terminal is obtained from the index data. I can't get it.
[0012]
On the other hand, according to the second prior art, the above inconvenience does not occur. That is, the CP stores the index data in the server, and the user transmits a search condition to the server via the Internet or the like. The server extracts data information satisfying the transmitted search conditions from the index data, and transmits the extraction result to the communication terminal. In this case, the user does not need to download the index data to the communication terminal in the first place, and therefore does not need to download the data for updating.
[0013]
However, when the CP makes the index data available to the user via the Internet or the like as described above, the user must always connect the communication terminal to a communication network such as the Internet while searching for the data. is there. Accordingly, data retrieval cannot be performed when it is difficult for the user to connect the communication terminal to a communication network such as the Internet. In addition, when a communication cost is incurred according to the time for connecting the communication terminal to the communication network, the user has to perform data search taking care of the communication cost, which is inconvenient.
[0014]
  In view of the above situation, the present invention does not download large-size index data, and all user data that can be downloaded from the server even when the communication terminal is not connected to the communication network. Enable searchTerminal device,Data distribution method, Program and recording mediumThe purpose is to provide.

[2: Data structure and operation of music instruction data distribution system]
[2.1: Outline of music teaching data distribution system]
The music instruction data distribution system is a system that distributes package data, which is data including music instruction information described in XML, from the server 1 to the communication terminal 3. A lot of package data is prepared by the CP, and the user downloads necessary package data from the server 1 to the communication terminal 3 and uses it.
[0040]
FIG. 2 schematically shows a part of the contents of the package data stored in the HD 104 of the server 1 with the file name “p0001.xml”. Since the package data is described in XML, the contents can be displayed by normal browser software. FIG. 3 shows an example in which the contents of the package data are displayed in browser software. As shown in FIG. 3, characters and images are displayed on the browser software by the package data.
[0041]
For example, the first character string in FIG. 3 is displayed by row L508 in FIG. Also, the first keyboard diagram shown in FIG. 3 is displayed by row L516 in FIG. In the line L516, image data having a file name “image001.img” is referred to. As described above, package data can refer to various external data. For example, when audio data or moving image data is referred to by package data, the user uses the browser software to input the audio data or moving image data. Data can be played back. When the program is referred to by package data, the user can execute the program using browser software. Hereinafter, displaying and reproducing data and executing a program according to data described in XML (hereinafter referred to as “XML data”) will be expressed as “execution” of XML data.
[0042]
As shown in FIG. 3, when package data is executed by browser software, information necessary for playing a musical instrument or the like is displayed on the display unit 306 of the communication terminal 3 as characters or images. Also, examples of musical instrument performance, accompaniment, and the like are pronounced from the speaker 312. Furthermore, based on the MIDI data generated by the performance using the user's MIDI keyboard 4 and the sound data generated by the performance using the microphone 5, the performance of the user is evaluated by a program executed by the package data. The user can learn the musical instrument performance by using these pieces of information. That is, the package data is content data including the content that is finally used by the user in the music instruction data distribution system of the present embodiment.
[0043]
As described above, a large number of package data is prepared by the CP according to the contents, and stored in the HD 104 of the server 1. The user of the communication terminal 3 needs to select the package data suitable for the purpose from the many package data, and download the selected package data from the server 1 to the communication terminal 3. In order to support the selection and download work, a music instruction application is prepared by the CP and stored in the HD 104 of the server 1. Therefore, the user first downloads this music instruction application to the HD 305 of the communication terminal 3, and then searches and downloads package data using the music instruction application. The music instruction application also has a browser software function, and the user can execute package data using the music instruction application.
[0044]
FIG. 4 shows the outline of various data stored in the HD 104 of the server 1 and the operation of the music instruction data distribution system using these data. First, a plurality of package data 401 is stored in the HD 104 of the server 1. Each package data 401 is attached with attached data 4011 such as image data, audio data, and a program that are referred to and used by the package data 401.
[0045]
The HD 104 further stores a plurality of summary data 402 corresponding to each package data 401. The summary data 402 is generated by summarizing the package data 401 (step S1), and includes a title, a content outline, a keyword, and the like in units of pages together with a package ID for identifying the corresponding package data 401. The summary data 402 is attached with necessary image data as attached data 4021 for data related to a preview page that can be executed by the user as a sample.
[0046]
The HD 104 further stores catalog data 403. The catalog data 403 is generated by summarizing a plurality of summary data 402 (step S2) and integrating them, and includes package IDs, titles, content outlines, keywords, etc. for all package data in units of package data. .
[0047]
The user of the communication terminal 3 first connects the communication terminal 3 to the Internet 2 and downloads the music instruction application 404 and the catalog data 403 from the server 1 to the communication terminal 3 (step S3 and step S4). When the communication terminal 3 finishes downloading, the communication terminal 3 disconnects from the Internet 2.
[0048]
Subsequently, the user uses the catalog search which is a search function using the catalog data 403 of the music instruction application 404 in the communication terminal 3 to obtain summary information of the target package data 401 (step S5). In the search using the catalog data 403, the content outline, keywords, and the like included in the catalog data 403 are used as search keys, and the package ID corresponding to the search key that satisfies the search condition input by the user is searched. The identification data indicating the data 403 is displayed together with the title and the like.
[0049]
Subsequently, the user connects the communication terminal 3 to the Internet 2, transmits a transmission request for summary data 402 corresponding to the target package data 401 to the server 1 (step S 6), and sends the summary data 402 to the communication terminal 3. Download (step S7). When the communication terminal 3 finishes downloading, the communication terminal 3 disconnects from the Internet 2.
[0050]
Subsequently, the user uses the summary search which is the search function using the summary data 402 of the music instruction application 404 and the summary display and preview which are the display functions of the summary data 402 in the communication terminal 3, and the target package data. Detailed information 401 is obtained (step S8). In the search using the summary data 402, as in the case of the search using the catalog data 403, the content outline, keywords, etc. included in the summary data 402 are used as search keys, and the search keys satisfy the search conditions. The corresponding package ID is displayed together with the title and the like as identification data indicating the searched package data 403.
[0051]
Subsequently, the user connects the communication terminal 3 to the Internet 2, transmits a transmission request for the target package data 401 to the server 1 (step S 9), and downloads the package data 401 to the communication terminal 3 (step S 10). . When the communication terminal 3 finishes downloading, the communication terminal 3 disconnects from the Internet 2.
[0052]
As a result, the user can execute the target package data 401 in the communication terminal 3 (step S11). As described above, when searching for target package data 401 from a large amount of package data 401, the user can first narrow down candidate package data 401 by using catalog data 403. Further, regarding the narrowed package data 401, more detailed information can be obtained from the summary data 402. The user does not need to connect the communication terminal 3 to the Internet 2 when using the functions of catalog search (step S5), summary search, summary display and preview (step S8), and package execution (step S11).

Further, package IDs and versions related to a plurality of package data 401 are registered for each set of user ID and password.
[0063]
After the registration process in step S103, the server 1 reads the music instruction application 404 and catalog data 403 from the HD 104, and transmits them to the communication terminal 3 (step S104). Upon receiving the music instruction application 404 and the catalog data 403, the communication terminal 3 disconnects from the Internet 2 (step S105).
[0064]
After the processing of step S104, the server 1 sets “application”, which is the ID of the music instruction application 404, as the package ID corresponding to the newly registered user ID, and the version of the music instruction application 404 as the version in the user management data. Is registered (step S106). The data line of the user ID “JOE415” in FIG. 10 indicates data registered in the user management data at the time when step S106 is completed.
[0065]
Subsequently, the user activates the music instruction application 404 in the communication terminal 3. When the music instruction application 404 is activated for the first time, the CPU 301 of the communication terminal 3 generates the data management data shown in FIG. 11 in accordance with the music instruction application 404, and uses the music instruction as downloaded data information in the generated data management data. Information on the application 404 and catalog data 403 is registered (step S107).
[0066]
In the data management data, the catalog data 403, summary data 402, package data 401, etc. downloaded to the communication terminal 3 are registered with their data type, ID and version.
[0067]
FIG. 12 shows a main menu screen displayed on the display unit 306 when the music instruction application 404 is activated. As described above, the music instruction application 404 is an application that causes the CPU 301 to perform search processing of the package data 401, execution of the package data 401, and the like. All processing of the communication terminal 3 in the following description is performed by the CPU 301. According to
[0068]
In a state where the package data 401 has not been downloaded to the communication terminal 3, the user cannot execute the package data 401 on the screen of FIG. Accordingly, the user clicks “catalog search” on the screen of FIG. 12, and searches for information related to the package data 401 to be downloaded using the catalog data 403 that has already been downloaded. In response to the user clicking “catalog search”, the CPU 301 displays a search condition input screen shown in FIG. 13 in the display window 901 of FIG. In the screen of FIG. 13, the user inputs search conditions and clicks “search”. In the screen of FIG. 13, the user can input search conditions that combine instrument names, musician names, content types, free keywords, and the like. The classification of keywords to be searched is not limited to instrument names, musician names, etc., and the classification may be freely selected.
[0069]
In response to the user clicking on “Search”, the CPU 301 executes a search process using the catalog data 403 (step S108). That is, the CPU 301 compares the search condition input by the user with the contents of the data included in the catalog data 403, and identifies the package data 401 that includes data that satisfies the search condition. Then, as shown in FIG. 14, the CPU 301 displays the package ID, title, and content outline of the identified package data 401 on the display window 901. At that time, the CPU 301 determines whether or not the retrieved package data 401 and the summary data 402 corresponding to the package data 401 are registered in the data management data, and their versions are the latest versions indicated in the catalog data 403. It is determined whether or not there is, and the result is displayed in a list of “package” and “summary” in FIG.
[0070]
For example, when the user inputs “Piano” as “instrument” on the screen of FIG. 13, the content of the data in the row L704 in the catalog data 403 of FIG. 6 satisfies the search condition input by the user. Therefore, the CPU 301 displays the package ID (line L702), title (line L717), and content outline (line L718) of the package data 401 including this data line on the display window 901.
[0071]
In the screen of FIG. 14, “-” shown in the “package” and “summary” lists indicates that the package data 401 and the summary data 402 corresponding to the package data 401 have not been downloaded. In these lists, in addition to “−”, “Δ” indicating that the data has been downloaded but not the latest version and “◯” indicating that the latest data has been downloaded are displayed.
[0072]
In the screen of FIG. 14, when “△” or “○” is displayed in the “Summary” or “Package” list, the user clicks “Summary Display” or “Package Display” to display the summary data 402 or the package. The contents of the data 401 can be displayed.
[0073]
In the screen of FIG. 14, the user can know the title and outline of the contents of the package data 401 including the contents that the user wants to use, and the package data 401 or the corresponding summary data 402 has already been downloaded to the HD 305 of the communication terminal 3. You can see if they have been updated and if they are the latest version. In order to obtain such information, the user does not need to connect the communication terminal 3 to the Internet 2.
[0074]
When the user wants to obtain more detailed information on the package data 401 for which “-” is displayed on the screen of FIG. 14, that is, the package data 401 not yet downloaded to the communication terminal 3, the line of the package data 401 And click “Summary Download / Update”.
[0075]
In response to the user clicking “Summary Download / Update”, the CPU 301 refers to the data management data (FIG. 15) and acquires the version of the catalog data 403. Further, the CPU 301 generates a summary ID of summary data 402 corresponding to the package data 401 from the package ID of the package data 401 selected by the user. For example, if the package ID of the package data 401 selected by the user is “p0001”, the CPU 301 generates “p0001-summary” as the summary ID. This summary ID indicates summary data “p0001-summary.xml”. Thereafter, the CPU 301 establishes a connection with the Internet 2 (step S109), and transmits a version of the catalog data 403, a summary ID, and a transmission request for the summary data 402 to the server 1 (step S110).
[0076]
When the CPU 101 of the server 1 receives the version of the catalog data 403, the summary ID, and the transmission request for the summary data 402, it first determines whether or not the received version of the catalog data 403 is the latest version. The version catalog data 403 is written from the HD 104 to the RAM 103. Subsequently, the CPU 101 writes summary data 402 corresponding to the received summary ID from the HD 104 of the server 1 to the RAM 103. Thereafter, the CPU 101 transmits the data written in the RAM 103, that is, the catalog data 403 and the summary data 402 or only the summary data 402 to the communication terminal 3 (step S111). When receiving the catalog data 403 and the summary data 402 or only the summary data 402, the CPU 301 of the communication terminal 3 stores the received data in the HD 305 of the communication terminal 3 and then disconnects the communication terminal 3 from the Internet 2. (Step S112).
[0077]
Subsequently, the CPU 301 of the communication terminal 3 registers information regarding the received data in the data management data (step S113). FIG. 15 illustrates the contents of the data management data after the user repeats the “summary download / update” instruction on the screen of FIG. 14 and the three summary data 402 are downloaded to the communication terminal 3.
[0078]
[2.3.4: Summary search]
Subsequently, the user displays the screen of FIG. 12 on the display unit 306 of the communication terminal 3 and clicks “summary search”. In response to a user operation, the CPU 301 causes the display window 901 to display the search condition input screen shown in FIG. In the screen of FIG. 13, the user inputs search conditions and clicks “search”.
[0079]
In response to the user clicking on “search”, the CPU 301 executes a search process similar to the search process in the “catalog search” using the summary data 402 (step S114). That is, the CPU 301 refers to all summary data 402 registered in the data management data, compares the search conditions entered by the user with the contents of the data included in the summary data 402, and specifies page data that satisfies the search conditions. To do. Then, as shown in FIG. 16, the CPU 301 displays the page ID, title, and content outline of the specified page data on the display window 901. At that time, the CPU 301 also displays the package ID and title of the package data 401 including the retrieved page data in the display window 901. Further, the CPU 301 refers to the data management data (FIG. 15) as in the case of the search process using the catalog data 403, and the package data 401 including the searched page data and the summary data 402 corresponding to the package data 401. Displays a symbol indicating the download status of.
[0080]
In the screen of FIG. 16, the user can know the title and summary of the contents of the page data including the contents that the user wants to use, and the package data 401 including the page data and the summary data 402 corresponding to the package data 401 are displayed. You can know the download status. In order to obtain such information, the user does not need to connect the communication terminal 3 to the Internet 2.
[0081]
When the user wants to obtain more detailed information about the package data 401 including a certain page data from the page data information shown on the screen of FIG. 16, the user selects the page data row and clicks “Summary Display”. . In response to the user clicking “summary display”, the CPU 301 displays the contents of the summary data 402 corresponding to the specified package data 401 on the display window 901 as shown in FIG. 17 (step S115). In the screen of FIG. 17, the user can obtain detailed information such as the title and content summary of each page of the package data 401 including the content to be used.
[0082]
When the user clicks “Preview” on the screen of FIG. 17, the CPU 301 is currently provided with the attribute value “Preview =“ Yes ”” included in the summary data 402 used in the display of FIG. 17. The contents of the data are displayed on the display window 901 (step S116). FIG. 18 illustrates a screen displayed on the display window 901 by the process of step S116. Thus, the user can execute a part of the package data 401 by the summary data 402. In order to obtain such information, the user does not need to connect the communication terminal 3 to the Internet 2.
[0083]
As described above, the user can obtain a lot of information related to the package data 401 on the screens shown in FIGS. 14, 16, 17 and 18. When the user wants to download certain package data 401 based on the information, the user selects a row corresponding to the package data 401 to be downloaded on the screen of FIG. 14 or 16 and clicks “package download / update”. Alternatively, “package download / update” is clicked in a state where the information of the package data 401 to be downloaded is displayed on the screen of FIG. 17 or FIG. Further, when the package data 401 has already been downloaded, but is not the latest version, the user similarly clicks “package download / update” (step S117).
[0084]
When the user clicks on “download / update package”, the CPU 301 causes the display window 901 to display a screen requesting the user to input a user ID and password. In response to the screen, the user inputs a user ID and a password. Subsequently, the CPU 301 acquires the version of the catalog data 403 from the data management data (FIG. 15). Further, the CPU 301 acquires the OS serial number, the CPU serial number, and the HD serial number of the communication terminal 3. Thereafter, the CPU 301 establishes connection with the Internet 2 (step S118), and the user ID, password, OS serial number, CPU serial number, HD serial number, version of catalog data 403, and the user downloads / updates the package. The package ID of the package data 401 selected when the user clicks "" and the transmission request for the package data 401 are transmitted to the server 1 (step S119).
[0085]
When the CPU 101 of the server 1 receives the above user ID and the like from the communication terminal 3 together with the transmission request for the package ID and package data 401, whether or not the received combination of the user ID and password is registered in the user management data (FIG. 10). Is determined (step S120). If it is determined in step S120 that the combination of the user ID and password is not registered in the user management data, the server 1 transmits an error message to the communication terminal 3 (step S121). When receiving the error message, the CPU 301 of the communication terminal 3 displays a screen requesting re-input of the user ID and password on the display window 901 (step S122).
[0086]
If a combination of user ID and password is registered in the user management data in step S120, the CPU 101 determines that all of the OS serial number, CPU serial number, and HD serial number registered in the data line of the user ID are It is determined whether or not the received OS serial number, CPU 301 serial number, and HD 305 serial number match (step S123). If any serial number does not match in the determination in step S123, the server 1 transmits an error message to the communication terminal 3 (step S124). When receiving the error message, the CPU 301 of the communication terminal 3 displays a screen for requesting the user to contact the CP support center on the display window 901 (step S125).
[0087]
The case where the serial numbers do not match in step S123 is a case where it is considered that the user is trying to download the package data 401 to different communication terminals 3. In that case, it is necessary for the user to contact the CP support center directly by telephone or the like and perform the procedure for changing the communication terminal 3. This is to prevent unauthorized use equivalent to unauthorized copying of the package data 401 by downloading the same package data 401 to a plurality of communication terminals 3 by the same user.
[0088]
If the serial numbers match in the determination in step S123, the CPU 101 determines whether or not the previously received package ID is registered in the same data row in the user management data (step S126).
[0089]
If it is determined in step S126 that the previously received package ID is not registered in the user management data, the communication terminal 3 newly requests downloading of the package data 401. Accordingly, the CPU 101 of the server 1 transmits a procedure request for a procedure for a new download of the package data 401 to the communication terminal 3 (step S127). When the CPU 301 of the communication terminal 3 receives the procedure request, the CPU 301 displays a procedure screen for requesting the user to pay for the usage fee of the package data 401 on the display window 901. When the user inputs necessary procedure information on the procedure screen and instructs transmission of the entered procedure information, the CPU 301 of the communication terminal 3 transmits the procedure information to the server 1 (step S128).
[0090]
On the other hand, if it is determined in step S126 that the previously received package ID is already registered in the user management data, the package data 401 corresponding to the package ID has already been downloaded to the communication terminal 3, but in the latest version, Means no. In that case, the processing related to the new download procedure shown in steps S127 and S128 is not performed.
[0091]
If the CPU 101 of the server 1 receives correct procedure information from the communication terminal 3 in step S128, or if the previously received package ID is already registered in the user management data in step S126, the CPU 101 received first. Package data 401 corresponding to the package ID is written from the HD 104 to the RAM 103. Subsequently, the CPU 101 determines whether or not the version of the previously received catalog data 403 is the latest version. If the received version of the catalog data 403 is not the latest version, the latest version of the catalog data 403 is transferred from the HD 104 to the RAM 103. Write. Thereafter, the CPU 101 transmits only the package data 401 and catalog data 403 written in the RAM 103 or the package data 401 to the communication terminal 3 (step S129).
[0092]
When receiving the package data 401 and catalog data 403 or only the package data 401 from the server 1, the CPU 301 of the communication terminal 3 stores the received data in the HD 305 and then disconnects from the Internet 2 (step S130). ).
[0093]
When the CPU 101 of the server 1 ends the process of step S129, the information of the package data 401 transmitted to the communication terminal 3 in step S129 is registered in the user management data (step S131). In FIG. 19, the user whose user ID is “JOE415” repeats the instruction of “package download / update” on the screen of FIG. 14 and the like, and three package data 401 are downloaded from the server 1 to the communication terminal 3. The content of user management data is illustrated.
[0094]
On the other hand, when the CPU 301 of the communication terminal 3 finishes the process of step S130, the received package data 401 or information related to the package data 401 and the catalog data 403 is registered in the data management data (step S132). FIG. 20 illustrates the contents of the data management data after the three package data 401 are downloaded to the communication terminal 3.
[0095]
When the user downloads the package data 401 from the server 1 to the communication terminal 3 as described above, the music data rule application 404 can execute the package data 401. The user displays the screen of FIG. 12 on the display unit 306 of the communication terminal 3, and clicks “execute package” on the screen. In response to the user clicking “Execute Package”, the CPU 301 refers to the data management data and the package data 401 stored in the HD 305 to display a selection screen for the package data 401.
[0096]
When the user selects package data 401 to be executed on the selection screen and gives an execution instruction, the CPU 301 executes the package data 401 selected by the user (step S133). As a result, the display window 901 displays a screen as illustrated in FIG.
[0097]
As described above, according to the present embodiment, the user downloads the catalog data 403 including information such as titles regarding all downloadable package data 401 and performs a search using the catalog data 403 to download the data. Information of desired package data 401 can be obtained. When candidates for package data 401 to be downloaded are determined by information obtained by searching using catalog data 403, summary data 402 corresponding to the package data 401 is downloaded, and searching using summary data 402 is performed. Thus, detailed information of the package data 401 can be obtained. When the user performs a search using the catalog data 403 and summary data 402, the communication terminal 3 does not need to be connected to the Internet 2.
[0098]
[3: Modification]
The above-described embodiment is an exemplification of the embodiment of the present invention, and various modifications can be made to the above-described embodiment without departing from the gist of the present invention. Hereinafter, a modification is shown.
[0099]
[3.1: First Modification]
In the above-described embodiment, the user management data stored in the HD of the server does not register information regarding catalog data and summary data downloaded by the communication terminal, and the information is stored in the HD of the communication terminal. Registered only in data management data. On the other hand, in the first modification, all the information included in the data management data is also included in the user management data. That is, when catalog data or summary data is downloaded by the communication terminal, the user ID, password, and various serial numbers are always verified, and the ID and version of the downloaded data are registered in the user management data.
[0100]
As a result, if the data management data of the communication terminal is lost due to reasons such as the OS being reinstalled on the communication terminal or the user wants to change the communication terminal using the music instruction application to another communication terminal, etc. Transmits a data re-download request to the server, and the server reconstructs the data management data corresponding to the user from the user management data in response to the request, and then is registered in the data management data and the data management data. Send various data to the communication terminal.
[0101]
According to the first modification, even if the data relating to the music instruction application cannot be used in the communication terminal for some reason, the user can easily reacquire the data.
[0102]
[3.2: Second Modification]
In the embodiment described above, the communication terminal is disconnected from the Internet except during user registration and downloading of various data. Such a form is effective in reducing the communication fee when the communication fee is charged for the time when the communication terminal is connected to the Internet.
[0103]
On the other hand, in the second modification, the connection between the communication terminal and the Internet does not necessarily have to be disconnected after data is downloaded. When the user performs a summary search, if the communication terminal is already connected to the Internet, the server receives data indicating a search condition and a search request in the summary search from the communication terminal, and based on the received search condition, A portion satisfying the search condition is extracted from the summary data stored in the server HD, and the extracted data is transmitted to the communication terminal.
[0104]
According to the second modification, the user does not need to download all of the summary data to the communication terminal. Therefore, when the communication fee is charged for the amount of data transmitted / received between the communication terminal and the Internet, the second modification is effective in reducing the communication fee. Even in that case, the user can narrow down the search conditions in the summary search without incurring additional communication charges by searching using catalog data, so download useless data from the server. Can be prevented.
[0105]
[3.3: Third Modification]
In the embodiment described above, all the data related to the music instruction application is stored in one server. On the other hand, in the third modification, a plurality of servers share the role of the data distribution server of the music instruction data distribution system.
[0106]
The catalog data in the third modification includes a URL (Uniform Resource Locator) indicating the storage location of each package data and each summary data. Each summary data includes a URL indicating the storage location of each package data. When the user instructs the communication terminal to download summary data or package data according to the catalog search result, or when the user instructs to download package data according to the summary search result, the communication terminal displays the catalog data or summary data. Using the included URL, a server for storing data instructed by the user is specified, and a data transmission request is sent to the server. When a server transmits data to the communication terminal in response to the data transmission request, the server transmits a user management data update request accompanying the data transmission to the other server. As a result, the same user management data content is maintained in all servers.
[0107]
According to the third modified example, even when the number of data related to the music instruction application and the total amount of data are large, it is not necessary for one server to store and manage all of them, so that the data distribution process is accelerated. In addition, data management by the CP is simplified. Further, since the communication terminal designates the data storage location to the server by the URL, the data search process when the server receives the data transmission request is speeded up.
[0108]
[3.4: Fourth Modification]
In the embodiment described above, the catalog data is updated when summary data or package data is downloaded to the communication terminal. In addition, updating of summary data and package data already downloaded to the communication terminal is performed according to a user instruction. On the other hand, in the fourth modified example, the catalog data, summary data, package data, and music instruction application are automatically updated when the connection between the communication terminal and the Internet is established.
[0109]
In the fourth modification, for example, when the OS of the communication terminal is activated, a program for automatically updating data related to the music instruction application is also activated and resides. This automatic update program constantly monitors the connection between the communication terminal and the Internet. When the connection is established, the communication terminal follows the automatic update program and sends data management data to the server along with a data update request. To do. When the server receives this update request together with the data management data, the server determines whether the version of each data registered in the data management data is the latest version. Is sent to the communication terminal. As a result, the data stored in the HD of the communication terminal is always kept up to date.
[0110]
The catalog search and summary search are performed using already downloaded catalog data and summary data without determining whether the version of each data is the latest version. In this case, the “summary download / update” button may be hidden or disabled on the search result display screens of FIGS.
[0111]
[3.5: Fifth Modification]
In the above-described embodiment, the search processing that can be performed by the user in the music instruction application is catalog search and summary search, and the summary search results show the page title and content outline. Also, keywords, content types, and free keywords can be specified by the user as search conditions.
[0112]
On the other hand, in the fifth modification, the user can perform more complicated search processing. The user can perform the search process using the already downloaded package data. As a result, it is possible to search for more specific contents that are not included in the keyword or the like.
[0113]
Further, the user can specify a unit for performing a search on a screen for specifying a search condition for the summary search. That is, not only a page unit search but also a section unit and package unit search can be performed. As a result, for example, when a search is performed in page units, when the number of results is too large, a suitable number of search results can be obtained by changing the search unit to a section unit or a package unit.
[0114]
[3.6: Sixth Modification]
In the sixth modification, the page data includes page IDs of other related page data, together with an attribute value indicating the relationship between the page data. Similarly, section data and package data also include section IDs and package IDs of other related section data and other package data, together with attribute values indicating the relationship between the data.
[0115]
The user can freely move to page data related to the currently selected page data or the like on a screen on which a catalog search or summary search result is displayed, or on a summary data or package data display screen. At the time of movement, the user can display the relationship between the page data of the movement source and the page data of the movement destination, and move between the data suitable for the purpose according to the relationship.
[0116]
According to the sixth modification, for example, even when the user cannot successfully search the target data according to a certain search condition, the target data is displayed by displaying the data related to the search result. Can be searched.
[0117]
[3.7: Seventh Modification]
In the seventh modification, the keyword or content type included in the currently executed or selected package data (or summary data corresponding to the package data) is displayed on the communication terminal without the user inputting a search condition. Based on the data, package data (or summary data corresponding to the package data) highly relevant to the currently executed or selected package data is automatically extracted.
[0118]
Various methods can be applied as automatic extraction methods. For example, the communication terminal uses the number of matches or the number of keywords included in the package data and the keywords included in the portion corresponding to each package data in the catalog data. The rate is obtained, and the titles of package data whose value is equal to or greater than a predetermined value may be displayed on the display unit in the order of the number of matches or the match rate. Further, a similarity table that defines parameters required for calculating the similarity between package data is stored in advance in the communication terminal, the communication terminal refers to the similarity table, calculates the similarity, and calculates the similarity The titles of the package data whose degree is equal to or greater than a predetermined value may be displayed on the display unit in descending order of similarity. In that case, the similarity table may be created by the CP and downloaded from the server to the communication terminal, or may be created by the user of the communication terminal.
[0119]
According to the seventh modified example, when the user executes or selects a certain data, information on the data related to the data is automatically shown, so that the user does not need to input search conditions or the like and is easily related. Data information can be obtained. Further, the CP can provide information regarding data suitable for the user's needs to the user without using direct mail or the like.
[0120]
[3.8: Eighth Modification]
In the above-described embodiment, the process of generating summary data from package data and the process of generating catalog data from summary data are performed using a computer other than the server by the CP, and the server has already generated the CP. Stored data.
[0121]
On the other hand, in the eighth modification, the server has a function of automatically generating summary data and catalog data from package data in addition to the functions of the data distribution server and the Web server.
[0122]
Specifically, the server periodically refers to the versions of all package data stored in the HD, and performs processing for storing the version information of the package data in a database (hereinafter referred to as “version database”). When the contents of certain package data are changed by the CP and the version of the package data is changed, the server newly updates the version information already recorded in the version database in the version information storage process that is performed periodically. Since the referenced version information does not match, the server detects that the contents of the package data have changed.
[0123]
When the server detects that the contents of the package data have changed, the server extracts specific data such as a title and an outline of the contents from the changed package data, and generates summary data. The server replaces the newly generated summary data with the new version number with the old summary data corresponding to the same package data. Subsequently, the server further extracts data for catalog data from the newly generated summary data, and generates data for updating the catalog data. The server replaces the data portion corresponding to the package data whose contents are changed in the catalog data with the update data generated from the summary data.
[0124]
According to the eighth modification, the change of the package data is automatically detected by the server, and the summary data and the catalog data are automatically updated. Therefore, the update operation of the summary data and the catalog data by the CP is simplified. The
[0125]
[3.9: Ninth Modification]
In the above-described embodiment, all data used in the music instruction data distribution system, such as a music instruction application and catalog data, are downloaded from the server to the communication terminal via the Internet. On the other hand, in the ninth modification, part or all of the data is recorded on a recording medium such as a CD-ROM (Compact Disc Read Only Memory) and can be distributed to users.
[0126]
More specifically, the communication terminal has a built-in drive for reading data recorded on a recording medium such as a CD-ROM, or can be connected as an external device. A recording medium on which necessary data is recorded is obtained by mail from the CP, and the data on the recording medium is read into a communication terminal for use. For example, the CP stores, in a recording medium such as a CD-ROM, the music instruction application and the catalog data (S104 in FIG. 7) that the user needs to obtain first when using the music instruction data distribution system in the above embodiment. It may be recorded and distributed to users.
[0127]
According to the ninth modification, the user can use the data distribution method according to the present invention even when it is difficult to connect to the Internet.
[0128]
【The invention's effect】
As described above, according to the data distribution method of the present invention, the user downloads catalog data including only summary information of a large number of data from the server device to the terminal device via the communication network, and thereafter the terminal Even if the connection between the apparatus and the communication network is disconnected, the target data can be searched using the catalog data. As a result, the user can search for the target data even when the terminal device cannot be connected to the server via the communication network. In addition, the user does not have to bear communication costs during the data search operation.
[0129]
Further, since it is determined by the terminal device based on the downloaded catalog data whether the already downloaded data is the latest version, the user can use the terminal device to confirm whether or not the data update is necessary. There is no need to connect to a server via a communication network.
[0130]
Further, when the user searches for data using catalog data, whether or not the data included in the search result has already been downloaded is determined based on the data management data in which the information of the downloaded data is registered Therefore, the user can avoid downloading the already downloaded data again by mistake.
