Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and method for distributing content corresponding to different types of terminals, and a computer program.

[0002]

2. Description of the Related Art In recent years, not only personal computers but also mobile phones and STBs (Set Top Boxes: home communication terminals) have been able to access the Internet and receive content distribution. Here, when creating a Web page as a content, usually, an HTML is used.
A description language called (Hyper Text Markup Language) is used. This description language is used to specify the color, font, size, paste destination, link destination, etc. of the image file. When this page is read by the browser (browsing software) installed in the terminal, the display is as specified. Is to be done.

[0003] By the way, a mobile phone (portable terminal) cannot browse a page described in the HTML language in terms of communication standards and data processing capability, but instead uses WML which is an original description language. (Wireless markup lang
uage), HDML (handheld device markup languag)
e), compact HTML or the like is used.

[0004]

However, the above-mentioned description languages have low compatibility, and there is a problem that contents described in a description language for a certain terminal cannot be browsed on another type of terminal. In this case, describing the content in a different description language for each terminal is not preferable in terms of the storage capacity and management of the Web server.

[0005] Therefore, it is conceivable to prepare content described in one description language and convert the description language according to the type of terminal that has accessed the Web site. However, if the tag corresponding to the description language tag of the conversion source content (the instruction portion surrounded by <>) does not exist in the conversion target description language, the content of the original content is not reproduced, or There is a problem that a problem (such as an error) is caused in the display of.

Further, since it takes time to convert the description language of the original content, there is also a problem that the waiting time until the terminal obtains the content becomes long.

[0007] The present invention has been made in view of the above-mentioned problems, and an identifier for designating the display of contents can be changed according to terminals of different types, so that the contents of the original contents can be reproduced and displayed on the terminals without any trouble. It is another object of the present invention to provide a content change distribution system and method that can reduce the waiting time on the terminal side.

[0008]

In order to achieve the above object, the content change distribution system of the present invention changes the identifier for designating the display of the content according to different types of terminals. An identifier change information database that distributes the content so that it can be displayed on the terminal and stores information related to the change of the identifier, a terminal determination unit that determines the type of the terminal, and an identifier determination unit that determines the type of the identifier in the content Based on the type of the terminal and the type of the identifier, extracting the identifier change information from the identifier change database, changing the identifier of the content according to the change information, and the identifier is changed. Distribution means for distributing content to the terminal.

Preferably, the identifier is a command symbol in a description language.

In the content change distribution system according to the present invention, when there is no identifier corresponding to the content identifier before the change as an identifier that can be displayed on the terminal, the identifier change information is stored in the content before the change. It is characterized in that it includes either a process for reproducing the function of the content identifier or a process for deleting the function.

[0011] When the function is to display a plurality of windows, the change information of the identifier preferably includes a process of deleting the identifier and displaying a link of any of the plurality of windows.

In the case where the function is to display an item corresponding to a code, the change information of the identifier may include a process of deleting the identifier and associating image data corresponding to the item with the content. preferable.

[0013] The identifier changing means changes an identifier for each semantic content in the content, and the distribution means includes:
It is preferable that the content changed for each semantic content is distributed to the terminal each time.

[0014] It is preferable that the apparatus further comprises a database for storing the contents.

According to the content change distribution method of the present invention, by changing an identifier designating the display of content according to a terminal of a different type, the content is distributed so as to be displayed on the terminal, and the change of the identifier is performed. Storing information about the terminal, and determining the type of the terminal,
Determining the type of the identifier in the content; extracting change information of the identifier based on the type of the terminal and the type of the identifier; and changing the identifier of the content according to the change information; Delivering the changed content to the terminal.

[0016] The computer program of the present invention, by changing an identifier designating display of content according to a terminal of a different type, causes the terminal to execute a content change distribution method of distributing the content so that the content can be displayed. A process of storing information relating to the change of the identifier, a process of determining the type of the terminal, a process of determining the type of the identifier in the content, the type of the terminal and the type of the identifier And based on
The method further includes a process of extracting change information of the identifier, changing the identifier of the content according to the change information, and a process of delivering the content whose identifier has been changed to the terminal.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a content change distribution system of the present invention (hereinafter, “this system” as appropriate).
FIG. 5 is a configuration block diagram illustrating an embodiment of the present invention. The system 50 includes an identifier change information database 2 and control means (terminal determining means,
(Identifier determining means, identifier changing means, distribution means) 6, and input / output control means 8 for transmitting and receiving information to and from the network 100. The control means 6 can be realized as a central processing unit of a server device constituting the present system, and the present system constitutes a Web site.

The present system 50 is connected to a network 100 and has a terminal 7 of a user who wants to distribute contents.
0, 72, 80, and 82 access the system 50 via the network 100. Here, the terminal 70
Is a personal computer, and terminal 72 is an STB (Set Top Box: home communication terminal) connected to the television. The terminals 80 and 82 are mobile phones, PHS (Pers
and a mobile terminal such as an onal handyphone system, which is connected to the network 100 via the mobile communication network 110. As the network 100, a dedicated line, a LAN (Local Area Network), a W
An AN (Wide Area Network) or the like can also be used.

Each of the terminals 70 to 82 has a browser capable of browsing a Web page, but the description language of the Web page that can be browsed by each terminal is different. For example, in the above-described embodiment, the terminals 70 and 72 can browse pages using HTML as the description language, the terminal 80 can browse pages using compact HTML (C-HTML) as the description language, and the terminal 82 uses WML as the description language. Page can be browsed.

Further, a plurality of content servers (Web servers) 20 to 24 are connected to the network 100, and the system 50 acquires contents requested to be distributed from the terminals 70 to 82 from these servers. I do.
In this embodiment, the content servers 20, 2
2 and 24 are HTML, C-HTML and WML, respectively.
(Web pages) 20a, 22 described in
a and 24a are stored. Also, each content server 2
0 to 24 store image files 20b to 24b corresponding to characters (pictograms, designs, etc.) represented by codes included in the contents 20a to 24a, respectively. The image file is in a known file format (for example, “JPEG format” etc.)
It should just be created in. When transmitting the content including the code to the present system, each content server transmits together the information in which the code is associated with (the address of) the image file.

Next, the configuration of the change information stored in the identifier change information database 2 will be described with reference to FIG. The “identifier” designates the display of the content (character color, font, size, image file pasting destination, link destination display, etc.), and includes, for example, a description language and a tag or script as its instruction part (symbol). (Program file). Then, when a page described by such an identifier (description language, tag, etc.) is read by a browser (browsing software), the display is performed as specified.

In FIG. 2, the change information (of the tag) is determined according to the combination of the description language of the original content and the description language after the change. For example, from HTML to WML
To change to C-HTML, and to change from C-HTML to HTML, change information 2b
(Browse on a terminal that can display multiple windows) to HTM
When changing to L (viewing on a terminal that cannot display multi-windows), the change information 2c is applied. The change information is a rule for changing the tag described in the original content to which tag after the change, and, if there is no tag corresponding to the description language after the change, which original tag is to be deleted Or information on what processing should be performed to reproduce the semantic content of the original tag. The specific contents of the change information will be described later.

Next, the configuration of the content (HTML document) 20a as the change source will be described with reference to FIG. First, a tag 20s of <HTML> indicating the type of the description language is placed at the beginning of the content 20a. This tag is paired with a tag 20x of </ HTML> at the end of the sentence. In the next line, a tag 20t of <xx> is placed in a pair with a </ xx> tag several lines later. In this case, since the portion sandwiched between <xx> and <// xx> has one meaning (for example, specifying the font of characters within this range), <xx> to <// × The range enclosed by “>” is referred to as one “semantic content”. Note that <
Xx> to <// xx> tag 20t, another <xx
If the XX> to </ XXX ×> tag 20u is included, this part is handled as a sub-item belonging to the above semantic content. Also, in the case of the <タ グ> tag 20v that represents the meaning of one group by itself, that part has one meaning. Further, <□□> to <// □□> tags 20w are placed on the next line, and the portion sandwiched between these tags has the following meaning. If information such as text is placed between the <HTML> tag 20s at the beginning of the sentence and the <xx> tag 20t on the next line,
This part may be regarded as one meaning content.

Next, with reference to FIGS. 4 and 5, a processing flow in the system 50, the terminal, and the content server will be described. In FIG. 4, the user accesses the present system by specifying the content desired to be distributed from the terminal (step S200). The access is, for example, U
What is necessary is just to specify RL (Uniform Resource Locator),
The content may be designated by inputting the URL of the content desired to be distributed on a predetermined screen.

The control unit 6 of the present system establishes a communication connection with the access terminal and also establishes a communication connection with the corresponding content server based on the URL of the content (step S100). Further, the control means 6 requests the content server to transmit the content (step S110).

The content server starts transmitting the requested content (step S300). If the communication environment between the content server and the system is good, the entire content is transmitted in a short time. Therefore, the system temporarily stores the content in a predetermined storage device (database, file, etc.) Is performed. On the other hand, when transmission takes time, the system continues to receive the content while performing the following processing. This way, rather than receiving and processing the entire content,
The waiting time on the terminal side can be reduced. When all the content has been transmitted, the content server ends the transmission (step S310 in FIG. 5).

Next, the control means 6 determines the type of the terminal and the description language (type of identifier) of the content (step S120).

First, the terminal type is determined by a communication protocol (for example, TC
(P / IP) by reading the contents. Specifically, TCP /
In the IP, “User-Agent” is included as a header included in the request content of the terminal at the time of communication, and the description content differs for each terminal type. For example,
User-Agent: For Mozilla / 4.7 [ja] (Win98; 1), "Mo
From "zilla", it can be seen that the description language supported by this terminal is HTML and the type of browser installed in the terminal. "/4.7" is browser version information. or,
"Ja"(Win98; 1) indicates information on the OS (operating system) of the terminal, and from this, the hardware and detailed functions of the terminal (for example, whether multi-windows can be displayed) can be known. Also, in the case of User-Agent: DoCoMo / 1.0 / P502i, it is known from "DoCoMo" that the description language is C-HTML, and from "P502i", detailed information on the terminal (for example, although the corresponding description language is the same, , And whether or not multi-window display is possible differs depending on the terminal).
Further, for example, when a mobile terminal employs a tag that is an extension of C-HTML, the detailed information of the terminal is used when the tag of the original content is changed accordingly. In the mobile communication network 110, communication is performed using a protocol different from TCP / IP. However, upon connection with the network 100, the communication is converted into the TCP / IP protocol by a predetermined gateway, so that the above-described determination is possible. It is.

The description language of the content is determined by reading the information at the beginning of the content transmitted in step S300. Specifically, since a tag indicating a description language is described at the beginning of the content (Web page), it is possible to determine the tag by this. For example, in the case of content described in HTML, <HTM
L> to </ HTML> tags are placed at the beginning and end of the sentence, respectively. Therefore, it is sufficient to read <HTML> at the beginning of the sentence. Note that, in C-HTML, the tag placed at the beginning of the sentence is <HTML> as above, so that it cannot be distinguished from HTML. However, since ordinary C-HTML is a reduced HTML function, the source of the change is There is no particular need to distinguish between the two languages. However, when C-HTML is used as a description language of a predetermined mobile phone service, a specific function (tag) may be added (for example,
C-HTML for “i-mode (registered trademark)” provided by NTT DOCOMO). In such a case, the added tag may be changed (deletion or change of the tag) based on the change information as described below.

Further, the control means 6 determines in step S120
The change information is extracted from the identifier change information database 2 (in the procedure described with reference to FIG. 2) based on the terminal type and the description language of the content determined in step S130 (step S130).

Next, the control means 6 reads the contents in order from the beginning of the sentence and for each semantic content (step S1 in FIG. 5).
40). The procedure for reading the content will be described with reference to FIG. 3 described above. First, the control unit 6 sets the <XX>
The tag 20t is read. Here, a predetermined storage device (database, file, etc.) stores one tag for each tag type.
The range to be recognized as one semantic content is defined.
According to this, when the <xx> tag is read, the next <
/ Xx> is defined to recognize the part up to reading the tag as one semantic content. In addition, the tag 20 of the pair
If there is a sub-item sandwiched between tags 20u in the semantic content sandwiched by t, this sub-item is read as information belonging to the semantic content sandwiched by tag 20t. In this way, the control means 6 reads the content for each single meaning content.

Next, the control means 6 refers to the change information extracted in step S130, and determines whether there is a tag to be changed in a portion sandwiched between the pair of tags 20t (step S130).
150). In the example of FIG. 3 described above, the tag 20t including <xxx> and </ xxx> and <xxxx> and </ xxxxxx>
The tag 20u consisting of is subject to change, but there may be a tag that does not necessarily need to be changed. If "Yes" in step S150, the tag is changed (step S160), and if "No", the changed content is distributed to the terminal without changing (step S170).

Further, the control means 6 determines whether all the tags have been changed and the distribution of the contents has been completed (step S180). This determination is made based on whether or not the </ HTML> tag 20x at the end of the sentence of the content shown in FIG. 3 has been read. If "No" in the step S180, the steps S140 to S170 are repeated, and the control means 6 reads the next meaning content from the content, changes the tag as appropriate, and distributes the tag to the terminal. In the case of FIG. 3 as an example, the portion surrounded by the tag 20v is read as one semantic content,
After making the determination in step S180, the portion sandwiched by the tags 20w is read as one semantic content. And
If "Yes" in the step S180, the communication connection with the terminal and the content server is terminated (step S19).
0). On the other hand, the terminal receives and displays the changed content for each meaning content each time, and the user browses the content (step S210). That is, a part of the content is sequentially delivered to the terminal for each meaning content.

Next, specific examples of the above processing will be described with reference to FIGS.
This will be described with reference to FIG. FIGS. 6 and 7 show an example in which content described in a description language without viewing restrictions is changed to content in a description language with viewing restrictions.

In FIG. 6, reference numeral 20a 'denotes the content of the change source (HTML document), and reference numeral 30 denotes the content after the change (WML document). Reference numeral 2a represents FIG.
This is the change information described in. Here, a case is considered in which a WML viewing terminal cannot display an italic display and an image file (restriction on viewing) due to hardware restrictions. Therefore, if the original HTML document is delivered as it is, a display error will occur on this terminal.

[0036] First of all, 'in the beginning of a sentence <HTML> tag 20s to the' original HTML document 20a is placed, the lower its being described text 40 of "Hello.".
On the next line, <i> to </ i> tags 20t 'are placed, and a text 42 "Italic characters will be written" is written between the tags. Here, the tag 20t 'is an instruction to display text within the range in italic characters. Further, an <img> tag 20v 'is placed on the next line, an image file (address) 44 to be imported is specified in the src attribute, and a text 46 to be displayed when the image cannot be displayed is specified in the alt attribute. Have been. At the end of the sentence, a </ HTML> tag 20x 'is placed.

The change information 2a includes the following processes 2a1-2.
a5 is included. First, with the change from HTML to WML, processing 2a1, 2a5 for matching the beginning and end tags with WML is defined. In WML, italics cannot be used, so that the processing 2a2, 2a3 for deleting the tag 20t 'is defined. Where "null"
Is a WML instruction for deleting the corresponding description. Furthermore, since images cannot be displayed in WML, the tag 20v 'is deleted, the ＠ attribute specified in the src attribute is ignored, and the {1 (text 4) specified in the alt attribute is ignored.
Process 2a4 for describing 6) on the page is defined.

According to the WML document 30 obtained by changing the HTML document 20a 'according to the change information 2a,
A tag 30s consisting of <wml> and <card> is placed at the beginning of the sentence, and a text 40 is placed directly below it.
The tag 20t 'is deleted, and the text 42 within the range is left as it is. Similarly, tag 20v 'is deleted,
The text 46 specified in the alt attribute therein is placed on the next line. And at the end of the sentence </ wml> and </ card>
Is placed. Thus, tag 20
By deleting t 'and 20v' and reproducing a part of the function (displaying the text 46), a display error on a WML-compatible terminal can be prevented.

FIG. 7 shows the original HTML document 20a '
A screen 500 displayed on an ML-compatible terminal (such as a personal computer) and a screen 510 displaying a WML document 30 on a WML-compatible terminal (mobile phone) are shown. Screen 50
0 includes a text 40, an italicized text 42 ′, and an image 44 corresponding to the file address 44.
a is displayed. On the other hand, the screen 510 displays the text 40
Are displayed in the same manner, but the text 42 is not displayed in italics, and the text 46 is displayed instead of the image. The file address 44 and the image (file) 4
The correspondence of 4a is stored in a predetermined storage device (database, file, etc.), and an image (file) 44a is acquired based on this. The storage device may be provided in association with the identifier change information database 2 in the system 50 or each of the content servers 20, 22, and 24.

Next, a case where the content described in correspondence with a terminal having the same description language but capable of multi-window display is changed to a content for a terminal which cannot display the content will be described with reference to FIGS. This will be described with reference to FIG.

In FIG. 8, reference numeral 20a ″ denotes the original content (HTML document corresponding to a terminal capable of multi-window display), and reference numeral 32 denotes the post-change content (HTML document corresponding to a terminal that cannot perform multi-window display).
L document). Reference numeral 2c is the change information described with reference to FIG.

First, in the original HTML document 20a ″,
An <HTML> tag 20s '' is placed at the beginning of the sentence, and a text 50 "index.html of the original window" is written below the <HTML> tag 20s ''. In the next line, a <window open> tag 20t '' is placed, and the addresses 52 and 54 of the windows to be opened are specified as attributes in the <window open> tag 20t ''. Here, the specific command name of the tag 20t '' is omitted. Also, instead of the tag 20t '', a script having a similar function (for example, Netsca
Script language called JavaScript developed by pe company)
May be used. At the end of the sentence, a </ HTML> tag 20x '' is placed.

The change information 2c includes the following process 2c1. In the process 2c1, since the multi-window display cannot be performed after the change, the tag 20t '' is deleted, and when one of the windows is displayed (single window), the other window is displayed as a link destination. . Since the description language itself is not changed, there is no need to change the tags 20s '' and 20x ''.

In the HTML document 32 obtained by changing the HTML document 20a ″ according to the change information 2c, tags 32s and 32x identical to the tags 20s ″ and 20x ″ are placed at the beginning and end of the sentence. The text 50 is left as it is under the tag 32s. The tag 20t ″ is deleted, and the addresses 52, 54 specified in the attributes therein are deleted.
Is placed as a link button. In this example, tag 20
By deleting t '' and reproducing the function (displaying the link button), it is possible to prevent a display error on a terminal in which the multi-window is not displayed. Functions similar to windows can be realized. Note that the currently opened window (page,
The address of “index.html”) may be displayed as the link destination. The conversion information in this case includes "index.htm
An instruction to acquire "l" and display a link may be included. This makes it easy to return to the original window.

FIG. 9 shows a screen 600 displaying the original HTML document 20a '' on a terminal capable of multi-window display (a personal computer or the like) and an HTML document 32 displayed on a terminal not capable of a multi-window display (STB or the like). The screen 610 is shown. The screen 600 includes an original window (address: index.html) 600a, a window 600b having an address of Sample1.html, and Sample2.html.
The window 600c having the address of the destination is displayed as a multi-window. Here, the text 50 is displayed in the window 600a.

On the other hand, only the original window (address: index.html) is displayed on the screen 610 (single window). Then, the text 50 is displayed on the window 610, and other windows are displayed as link buttons 52 'and 54'.

Next, a case where contents described in a description language capable of displaying predetermined code characters are changed to contents in a description language incapable of displaying the same will be described with reference to FIGS.
This will be described with reference to FIG.

In FIG. 10, reference numeral 22a denotes the content of the change source (C-HTML capable of displaying predetermined code characters).
Reference numeral 34 indicates the content after the change (an HTML document in which predetermined code characters cannot be displayed). Also, code 2
b is the change information described in FIG.

First, in the original C-HTML document 22a,
A <HTML> tag 22s is placed at the beginning of the sentence, and a text 60 of "ordinary character. Hereinafter, pictogram." On the next line, an instruction 22t of &# is placed, and a code (code number 63650) 62d for specifying a character is specified in the attribute therein. Further, on the next line, an instruction 22u of “•” is placed. The instruction 22u means the code (code number 63651) 62e itself for specifying a character.
If the code design is not defined in the terminal that displays the HTML document 22a, a predetermined symbol is displayed instead of a character (in the figure, it is illustrated as “•”). Therefore, even if different codes are described in the document 22a, they are all displayed as “•”, but when the document 22a is read, each code (code number) is read.
Is identified. In the present invention, such a code designation itself is included in the “identifier”, like the tag.
At the end of the sentence, a </ HTML> tag 22x is placed.

The change information 2b includes the following processes 2b1-2.
b6 is included. The process 2b1 has a code 6 after the change.
Since character display by 2d cannot be performed, the above command 22
t and, instead, <im
g> tag is added. Here, “$ 1” is a variable, and the code “$ 1” is replaced with a corresponding image file “$ 1.jpg”, for example. Further, in the processes 2b2 to 2b6, when the code specification itself is an instruction ("." Symbol in the drawing) instead of the instruction 22t, "." Is deleted and <img> recognizable by HTML.
A tag is added. Here, in process 2b1,
The code 62d is read and specified as the src attribute of the <img> tag, and in processes 2b2 to 2b6, the code specification itself (62e or the like) is read and specified as the src attribute of the <img> tag. In this case, in each of the processes 2b2 to 2b6,
The code number specified as the src attribute corresponds to the code number indicated by each code specification “•”. The correspondence between each code number and the image (file) 64a to 64e is stored in a predetermined storage device (database, file, etc.), and the image (file) is obtained based on this. In HTML, the process of changing the C-HTML tags 22s and 22x is unnecessary.

According to the change information 2b, the C-HTML
In the HTML document 34 obtained by changing the document 22a, the same tags 34s and 34x as the tags 22s and 22x are placed at the beginning and end of the sentence, and the text 60 is placed under the tag 22s as it is. Instructions 22t, 22u are deleted, and tags 34t, 34u are placed instead. As the attributes of the tags 34t and 34u, (the addresses) 64d and 64e of the image files corresponding to the codes 62d and 62e are designated. In this example, the instructions 22t and 22u are deleted and their functions are reproduced (tags 34t and 34u are added).
Thus, a display error on the terminal can be prevented, and not only the function can be simply deleted but also a function equivalent to the code character display can be realized.

FIG. 11 shows a screen 700 displaying the original C-HTML document 22a on a terminal (mobile phone), and HTML.
A screen 710 showing the document 34 on a terminal (a personal computer or the like) is shown. The screen 700 includes the text 60,
And pictographic characters (code characters) 62'd, 62'e corresponding to the codes 62d, 62e, respectively.
On the other hand, the screen 710 displays the text 60 and the code 6
Images 64d and 64e respectively corresponding to 2d and 62e are displayed.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the content server is provided separately from the present system, but the content server may be provided in the present system. Also, as for a method of accessing the present system from a terminal, for example, the present system (server) may be set as a proxy on the terminal, and a predetermined content server may be accessed.

Further, the processing included in the change information is not limited to the above, and any processing may be used as long as it prevents the trouble caused by the change (for example, deletes, corrects, adds, etc. the original instruction). For example, when the content is changed corresponding to a terminal that cannot display a multi-window, the position at which the link destination (link object) is displayed (inserted) can be freely determined. If the code number specified as a code character differs depending on the description language, a process of mutually changing the code numbers may be performed. Further, the present invention can be applied to a case where a face character (face mark) based on a combination of character strings corresponds to a code instead of a pictogram.

The content change distribution system of the present invention includes a computer, various peripheral devices such as a communication device, and the like.
It can be realized by a software program operated by a computer. This software program can be distributed via a computer-readable storage medium or a communication line.

[0056]

As described above, according to the present invention,
Since the identifier for designating the display of the content is changed according to the terminal and the content is distributed, the content of the original content can be reproduced and displayed without a problem even with a terminal of a different type. In particular, if there is no corresponding identifier after the change, delete the original identifier,
In addition, by changing the function of the original identifier to be reproduced, it is possible to prevent a display error on the terminal,
In addition to simply deleting the function, it is possible to realize a function equivalent to the original content.

Further, by changing the identifier for each semantic content of the content and delivering the content, the waiting time on the terminal side can be reduced as compared with the case where the entire content is changed and delivered.
