Description

TECHNICAL FIELD The present invention relates to a content providing method for distributing content data to an Internet terminal connectable to the Internet.
BACKGROUND ART In recent years, the Internet, which is an open network of computers, has been remarkably popularized, and the usage of personal computers has been increasing, and the use of the Internet has been shifting from corporate business use to personal use. It is increasing rapidly.
On the other hand, with the spread of mobile phones in recent years, an Internet connection service that enables these mobile phones to connect to the Internet has been provided. Since it becomes possible to obtain desired information and various contents such as music and images, the number of users is rapidly increasing. In the future, mobile communication that can access the Internet through wireless lines such as mobile phones will be continued. The number of users is expected to increase further due to its convenience and quick access to information.
As described above, the Internet, which was owned by some people until several years ago, is indispensable to many people with the spread of personal computers to homes and the spread of mobile phones with Internet connection functions. It is becoming an information means (tool) that can not be done.
Therefore, when considering a corporate strategy, it has become indispensable to install a Web server for a company to provide or transmit contents such as information as publicity and publicity and an EC (Electric Commerce) site.
However, with the spread of mobile terminals such as mobile phones having the Internet connection function, in the case of constructing a Web server that also targets these mobile terminals, it is necessary to make these mobile terminals portable terminals. Since it is relatively small and it is difficult to mount a computing device with a large processing capacity due to power restrictions due to the power from the battery, a script is added to the content to be distributed. Depending on the model of the terminal and the type of browsing software, there are some that can and cannot process scripts, and in Internet terminals that cannot process scripts, it is not only possible to receive the benefits of these scripts , With a terminal capable of processing these scripts We also there are cases where the display of rapid content by reducing the available processing power to the display processing of other content processing power is used for these script processing can no longer be made.
In addition, since these scripts also have a description language, even if the Internet terminal has the processing ability to process the script, the script cannot be understood or understood depending on the terminal model and the type of viewing software. In order to be able to cope with these various scripts, there is a problem that the user has to attach the script and construct the contents in consideration of the model of the terminal and the type of the viewing software.
Therefore, the present invention has been made by focusing on the above-described problems, and there are inconveniences due to the fact that there are those that can or cannot process a script depending on the terminal model and the type of browsing software, and the processing accompanying these script processings. Provide a content providing method that can easily implement content using a script without being aware of the terminal model or the type of browsing software for the inconvenience due to an increase in load and for content creators. It is aimed at.
DISCLOSURE OF THE INVENTION In order to solve the above-mentioned problem, a content providing method of the present invention provides a content providing content data to an Internet terminal connectable to an Internet network using a server computer connected to the Internet network. The method,
A script execution step of executing the script when the content data to be distributed to the Internet terminal includes a script language;
A distribution step of distributing the script-processed content based on the script execution result to the Internet terminal;
At least.
According to this feature, since the script processing is performed on the server computer side, even if the terminal model or the browsing software cannot process the script, it can not only receive the advantages of the script, Even for terminals that can process scripts, the processing load required for script processing can be reduced.Therefore, there are some terminals that can or cannot process scripts depending on the terminal model and the type of viewing software as described above. The inconveniences associated with these scripts and the increased processing load associated with script processing can be eliminated.Furthermore, content creators can construct content using scripts without being aware of the model of the terminal or the type of viewing software. It can be easily implemented.
It is preferable that the content providing method of the present invention includes a description format conversion step of converting the content data to be distributed to the Internet terminal in the distribution step into a description format corresponding to an access method of the Internet terminal.
With this configuration, the content data is simply registered in the computer (server) in a file format of a predetermined format, and the content data is converted into a description format corresponding to the access method of the Internet terminal accessed in the description format conversion step. Since the content data is converted and distributed to the accessing Internet terminal, it is not necessary to convert each element of the huge content into each description format for each access method in advance as in the related art. The content data can be centrally managed in one file format of a predetermined format, so that the time and cost for updating the content can be significantly reduced, so that maintenance and development of the content data can be easily performed. It can be implemented. Further, since the content data can be centrally managed in one file format of a predetermined format, there is no need to provide addresses (URLs) for each description format, and these addresses (URLs) are the same for each access method. Therefore, the access user can use the same address (URL) even when the type of the Internet terminal used is different, and the user can easily understand and improve the convenience.
In the content providing method according to the present invention, the type of the Internet terminal or the type of the viewing software is obtained by obtaining type information capable of specifying or estimating either the type of the Internet terminal or the type of the viewing software installed in the Internet terminal. A type identification step of identifying
The content size corresponding to the type of the Internet terminal or the type of the viewing software specified in the type specifying step is compared with the content size to be distributed in the distribution step, and the content size to be distributed in the comparison is In the case of a large size, a page dividing step of dividing the content size to be distributed to a content size corresponding to the type of the Internet terminal or the type of the viewing software,
Preferably, the divided pages are distributed in the distribution step.
By doing so, it is possible to solve a situation where the size of the content data exceeds the content size that can be received by the Internet terminal, and the excess portion is not displayed or the entire content is not displayed.
In the content providing method according to the present invention, when there is image data cited in the content to be distributed in the distribution step, the cited image is converted to an image corresponding to the type of the Internet terminal or the type of browsing software. An image file conversion step for converting to a file format;
An image file name updating step of changing the quoted image name in the content data to be distributed to the converted image name,
It is preferable to include
In this way, it is possible not only to avoid the trouble of pre-registering the image data quoted in the content for each image file format usable in various Internet terminals, but also to update these image data. Work can also be easily performed.
In the content providing method of the present invention, when the content to be distributed in the distribution step includes quoted image data, the content corresponds to the size of the quoted image and the type of the Internet terminal or the type of browsing software. Reducing the size of the image file to an image size smaller than the display screen size when the size of the image file is larger than the display screen size in the comparison. It is preferred to include.
In this way, it is possible to avoid a situation where the entire image is not displayed on the display screen of the Internet terminal.
The content providing method of the present invention is a unified pictogram conversion for converting pictograms included in a request message transmitted from the Internet terminal into unified pictograms using a pictogram table corresponding to the type of the Internet terminal or the type of viewing software. Steps and
A unique pictogram conversion step of converting unified pictograms contained in the content data to be distributed in the distribution step into pictograms specific to the type of Internet terminal to be distributed or the type of browsing software;
It is preferable to include
In this manner, conventionally, when the terminal model and the like are different from each other, since the emoticons incorporated in the terminal are also different, the content creator is familiar with the emoticons for each terminal type. However, the content creator can easily use the pictograms without having to learn the differences between the pictograms due to the differences in the terminal models and the like.
BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

May be a PDA terminal that can be accessed.
Further, in this practical example, the server computer 6 is connected to the central control stations 3b, 3c, and 3d of the respective carrier companies via the Internet network 4, but the present invention is not limited to this. It is optional to connect the central control stations 3b, 3c, 3d and the server computer 6 with a dedicated line or the like.
Also, a content provider that transmits information and the like is provided with a computer terminal 7 that is connected to the server computer 6 installed in the distribution center 5 via the Internet network 4 so as to be able to perform data communication. By accessing the server computer 6 using a computer terminal 7, the server computer 6 can update the content data provided to the access user.
In the present embodiment, as shown in FIG. 7, the server computer 6 has registered therein terminal information of each carrier and a mobile phone terminal used in each carrier, information of a browser serving as viewing software, and the like. An information table and a pictogram table in which conversion information such as pictograms used in each terminal and browser are registered are registered, but these terminal information tables and pictogram tables are available in new models and new versions. Since it is released successively, it is necessary to add and update information sequentially in order to cope with these. Therefore, an updating computer terminal 8 for updating these terminal information tables and pictogram tables is installed in the management center, The server computer 6 is periodically connected to the updating computer terminal 8 via the Internet 4. By accessing, and performs the update of the terminal information table and pictogram table are registered.
In the configuration of the server computer 6 used in this embodiment, as shown in FIG. 2, the operation control of the server computer 6, in particular, the data bus 20 for transmitting and receiving data inside the server computer 6 is accessed. Based on a predetermined processing program, control for managing the state of data exchange (session) with the computer terminal 1a and the mobile phone terminals 1b, 1c, and 1d of the respective carriers is performed, and the content data is distributed to the computer terminal 1a or the mobile terminal. A central processing unit (CPU) 21 that performs a process of converting to a file format that matches the access system of each carrier of the telephone terminals 1b, 1c, and 1d based on a “cross-sublet (X-Servlet) engine” that is a file conversion program. , Temporary processing data and the like in the conversion processing A RAM 24 for performing storage, a real-time clock (RTC) 26 capable of outputting time information such as an access time, a communication interface 22 enabling data communication with the Internet 4, and a display device such as a display And a control program in which various kinds of control executed by the central processing unit (CPU) 21 are described, and the file conversion program is a “cross-sublet (X-Servlet) engine”. And a content database (DB) in which information provided by a content provider is registered, and a terminal in which terminal information of a mobile phone terminal used in each carrier and information of a browser serving as viewing software are registered. Use in information tables, terminals and browsers The storage device 25 in which a pictogram table or the like in which conversion information such as pictograms or the like are registered is recorded, is connected to the storage device 25, and is a normal computer capable of performing relatively high-speed processing. A single (common) server address (URL) that can be used when accessing from the computer terminal 1a or the mobile phone terminals 1b, 1c, and 1d of each carrier is assigned.
Next, an outline of a process in which the server computer 6 of this embodiment distributes content data to the computer terminals 1a and the mobile phone terminals 1b, 1c, and 1d of the respective carriers will be described with reference to FIG. When accessing the server computer 6 from the mobile phone terminal 1b, the server computer 6 first determines the carrier of the mobile phone terminal 1b based on the user agent information included in the header of the request message from the mobile phone terminal 1b. By extracting information capable of identifying the type and the model of the terminal, and obtaining information such as the type of the access method (markup language) of the carrier corresponding to the information and the display performance of the terminal from the terminal information table, The content data requested by the request message is stored in the content database. More available.
The content data read from the content database is converted into a file in the HDML format, which is the access method of the carrier company B of the mobile phone terminal 1b that has accessed the mobile phone terminal 1b. Based on the information such as the display performance, which is the terminal information of the terminal 1b, the converted HDML is displayed so as to display a layout that matches the number of display lines and the number of digits of the display device (LCD panel) of the mobile phone terminal 1b. The file is appropriately modified, for example, divided into pages, and transmitted and distributed to the mobile phone terminal 1b. As shown in FIG. In the case of the terminal 1a, the terminal that has accessed the file (description) format of HTML is the carrier C company. Or carrier D, the content data is converted and converted into MML and C-HTML file (description) formats, respectively, and transmitted and distributed. Since the content data can be obtained more, the content provider registers and updates the information to be provided in the server computer 6 so that the same server address (URL) and a mobile phone or a computer of a different carrier can be used. Content can be distributed to all terminals.
Hereinafter, the content data providing process in the server computer 6 according to the present embodiment will be described in detail with reference to FIG.
First, a request message from the computer terminal 1a or the mobile phone / mobile phone terminal 1b, 1c, 1d (hereinafter collectively referred to as an Internet terminal) used by the access user is activated in the server computer 6. The terminal type ID, the session ID, and the parameters received by the servlet engine and capable of specifying the type of the carrier and the terminal included in the request message are sent to the cross-sublet core program.
As a method of obtaining the terminal type ID, as shown in FIG. 5, the user agent information is included in the HTTP header transmitted at the beginning of the request message, and the user agent information includes As shown in FIG. 5, information specific to each carrier is described, and the model of the Internet terminal that transmitted the request message and the version information of the browser are also described. The carrier and the type of the terminal can be identified by checking the terminal information table shown in FIG.
The specific processing content of the terminal type identification processing for specifying the terminal type based on the description data in the extracted user agent information is as shown in FIG. 6, and the acquisition of the description data of the user agent information , A carrier name included in the description data and a word indicating the type (model) of the terminal are detected.
Next, the terminal information table is searched using the detected carrier name and terminal model name as search keywords. At this time, if there is no corresponding registration, the terminal information table is searched again with the model identification information as “default”. If this still does not apply, the carrier suggestion information is set to “default”. The registration information corresponding to the carrier suggestion information and the model identification information determined in this way, for example, the format of the markup language, the maximum number of bytes of the content, the number of lines of the display screen, the number of characters, and the like are obtained from the terminal information table, and thereafter, Applies to content conversion processing and the like.
If no word indicating the carrier name and the type (model) of the terminal has been extracted or there is no corresponding word in the search of the terminal information table, the carrier company and the terminal registered in the terminal information table A data input screen configured so that the access user can select and input each information of the model is returned to the Internet terminal that sent the request message, and when the carrier company and the terminal model are selected by the access user, Then, the terminal information table is searched for and acquires information on the selected carrier company and terminal model.
As described above, in the case where the carrier company and the terminal model cannot be specified from the request message, returning the data input screen to the access user's Internet terminal and accepting the information on the carrier company and the terminal model is performed by these carrier companies. In addition, since the terminal model is unspecified, it is possible to avoid inconvenience that inappropriate conversion processing is performed in the subsequent content conversion processing and the like. However, the present invention is not limited to this.
The configuration of the terminal information table used in this embodiment used in the terminal type identification processing and the like is as shown in FIG. 7, and corresponds to the "name" of "browser" corresponding to each carrier company and the model. The “name” of the “terminal”, information on the receivable content (“name” of the “markup language”, the character code of the content, the maximum number of bytes of the content), and information on the size of the terminal screen (the “screen” "Number of horizontal characters" and "number of vertical lines"), information on images that can be displayed ("format" of "image", "number of horizontal pixels", "number of vertical pixels", "aspect ratio", "whether animation", " Information such as “color mode” and “color / gradation number” is registered, and these terminal information tables are regularly updated to the latest ones by an update process described later.
Then, in the cross-sublet core program, as shown in FIG. 4, session information acquisition processing is performed, and the specific processing contents of these session information are as shown in FIG. That is, if the request message does not include a session ID, the request message is recognized as a new session, and a session ID is created. Then, the session is stored and managed in the G0 set when the session is equal to or less than the reference life span, and otherwise stored in the other set.
Here, the G0 set is a set that manages all sessions that have been accessed between a certain time and the reference life time (however, those whose lifespan is equal to or less than the reference life). When the current time has passed “the time obtained by adding the reference life time from a certain time”, the G0 set is managed by changing the name to the G1 set. Then, the G0 set is newly defined as “from the current time to the time obtained by adding the reference life time”. When the G0 set is changed to the G1 set, if the G1 set already exists, its contents are all discarded. As a result, it is possible to efficiently delete invalid sessions.
Here, if the request message includes the session ID, the expiration date of the session ID is checked. If not, the session is discarded and a new session ID is acquired as described above. If the session is valid, the last access time of the session is updated and stored in the G0 set or a set other than G (other).
The session is identified and the session is identified using the session ID as a key. After that, processing such as acquisition and conversion of content is performed, and before HTTP Cookie is available before responding to the user with the processing result, the session ID is set to Cookie and the user is responded with the content processing result. When the Cookie cannot be used, session ID information is added to all the link destination URLs included in the content and the user is responded to. Note that even if the HTTP Cookie can be used, the HTTP Cookie may not be used.
Next, the pictograms and character codes included in the request message, based on the conversion contents registered in the pictogram table corresponding to the carrier company and terminal model information obtained in the terminal type identification processing, The emoticons and character codes to be converted are converted into predetermined ones.
Based on the request message converted into the predetermined character code, the requested content data is specified, the corresponding content data is obtained from the content database (DB), and a document object model (DOM) is created.
After the creation of the document object model (DOM), the server computer 6 performs a script execution process. The processing content of the script execution process in the present embodiment is as shown in FIG. 12, and the content obtained from the content database (DB) based on the request message is scripted (for the program processed on the user terminal). If the type is included, the script is executed on the server computer 6, the values of variables and the like are set, and the content (display image) of the screen to be displayed is determined.
The content (display image) thus determined is subjected to content conversion and pictogram conversion processing to respond to the user. At this time, a standard style sheet is provided for converting the content. Note that the script is used to change the value of a variable or the like in accordance with the operation of the user, and to change the display screen only by processing on the user terminal. In the case of this embodiment, the result of the user operation is , Is transmitted to the server as a request message, and the server performs this processing.
After these script processes, the content data conversion process is performed. The contents of the content data conversion processing in this embodiment are as shown in FIG. 9. If the content requested by the request message has already been converted and exists in the cache, the specified page of the specified content is read from the cache. And respond to the user. If the content does not exist in the cache, the content is obtained by executing a server-side application program such as a servlet, and the content is converted based on the terminal information.
At this time, if the size after the conversion exceeds the content size that can be received by the terminal (specified in the terminal information table), the acquired content is viewed from the end, and the obtained content is separated (selection list, The content is divided and pictograms are converted again for the first divided part. This is repeated until the content size becomes a size that can be received by the terminal, and one or both links of “previous page” or “next page” are added to each page, and each of the divided pages is provided to the user. The page that responds. Then, for the unprocessed portion of the first content, the content conversion, pictogram conversion, and size check are repeated in the same manner, all the content is converted, all pages are created, and registered in the cache. Thereafter, the user is notified of the specified page (or the first page if no page is specified).
The display situation by page division in the file conversion process will be described with reference to FIG. 10. If the content size exceeds the size (number of characters) that can be received (displayable) by the terminal, the content must be divided into pages. As shown in FIG. 10, a part of the content is not displayed or the entire content is not displayed.
On the other hand, when the page division is performed as described above, as shown in FIG. 10, by sequentially moving the divided pages, it becomes possible to display all the content contents without omission. When a divided page is moved, by providing one or both links of a “previous page” and a “next page” as in the present embodiment, the movement between pages can be easily performed. However, the present invention is not limited to this.
If a quoted image exists in the file-converted content data, image data conversion processing of the quoted image is performed. Specifically, as shown in FIG. 8, when an image is requested in the request message, the specified image name (eg, a.gif) and the identified terminal name (eg, N502i) ) As a key to search the cache. If the corresponding data exists in the cache, the designated image a. The digest value of gif is calculated and compared with the stored digest value.
If the two match, it is determined that the designated image has not been changed, and the converted image data stored in the cache is returned to the user as a response. Except in this case, the designated image a. If the size of the gif is large, compression processing is performed; if the number of colors is large, color reduction processing is performed; if the format is different, format conversion is performed, and the processing result is returned to the user. At this time, a. If the digest value for gif already exists in the cache and it is different from the value calculated this time, a. Discard all the cache contents related to gif. And a. gif digest value and image name a. The converted image is stored in the cache using the gif and the terminal name N502i as keys.
As described above, when converting image data, it is determined whether or not the data corresponding to the converted image data already exists in the cache, and if so, the conversion process is not performed. Although it is preferable because the processing load involved in the processing can be reduced, the present invention is not limited to this, and image data may be uniquely converted to update cache data.
Further, in addition to the conversion of the image data, conversion processing of pictograms and character codes in the converted content data is performed. These processing contents will be described as specific processing contents based on the flow of FIG. 13 as a series of processing together with the conversion of pictographs and character codes in the request message. If the URL specified in the request message is stored in a server side such as a servlet, If the program is to be executed, the pictograph code included in the request message is converted into a unified pictograph code by searching the "pictograph table". Further, the request message is converted into a character code assumed by the designated server-side program. Thereafter, the server-side program is executed, and the content is obtained as a result.
When the URL specified in the request message is not the execution of the server-side program, the content may be obtained from the specified URL, for example, the computer terminal 7 of the content provider.
Along with converting the character code of the content obtained in this way to the character code of the output terminal, all the pictograph codes included in the content are converted to pictograph codes for the output terminal by searching the `` pictograph table '', Respond to the user.
The "pictogram table" and the "information terminal table" are updated periodically by performing the update process shown in FIG. 14 and accessing the computer terminal 8 of the management center to update the data. Is to be updated. More specifically, the terminal accesses the computer terminal 8 of the management center at regular intervals, issues an inquiry, and acquires the update time of the “terminal information database” registered in the computer terminal 8. If this time is later than the time managed by the server computer 6, a request message is issued to the computer terminal 8, the “terminal information table” is downloaded from the computer terminal 8, and the Update the registered contents.
As described above, according to the present embodiment, it is possible to provide not only an Internet terminal that does not have the ability to process a script in a format included in content but also content such as a display image accompanying the script processing, Even with Internet terminals that can process these scripts, the processing load on the Internet terminals associated with the processing of these scripts can be greatly reduced, and the limited performance records of the Internet terminals can be used for other processes. become.
In addition, even the creators of these contents can construct contents using a script without being conscious of the type of terminal, the type of viewing software, the type of script language, and the like. Construction of the used content can be facilitated.
As described above, the embodiments of the present invention have been described in the above embodiments with reference to the drawings. However, the present invention is not limited to these embodiments, and changes and additions may be made without departing from the gist of the present invention. Needless to say, this is included in the present invention.
For example, in the embodiment, the server computer 6 converts the content data to be distributed into a description format corresponding to each access method so as to correspond to each access method of each of the carrier companies A, B, C, and D. Although the conversion is performed, the present invention is not limited to this. There are many types of mobile phone terminals and the like of a single carrier company B, and some of them can execute a script. Since some scripts cannot be executed if they exist, the present invention may be applied to a server computer that supports only a single access method.
Further, in the above-described embodiment, the format of the conversion file converted from the content data registered in the content database is exemplified by the HDML format, the C-HTML format, and the MML format. However, the present invention is not limited to this. Instead, these file formats may be the XHTML format, which is a next-generation file format.
Further, in the present embodiment, the conversion from the content data registered in the content database to each file format is performed directly. However, the present invention is not limited to this, and the conversion to each of these file formats is performed. In the conversion, the conversion into an XML file may be performed once as an intermediate file, and then the conversion into a file in each desired format may be performed.
