Further, the link information collection and provision apparatus 1 and the content conversion apparatus 2 may be configured as an integrated content conversion apparatus or content conversion system.
(System operation)
Next, the operation of the content conversion system according to the present embodiment will be described with reference to the sequence charts shown in FIGS.

  As shown in FIG. 4, first, the link information collection / providing device 1 receives a link information collection request from the terminal device 4 (step 1). This link information collection request is, for example, an RSS subscription request or a web search request. In the link information collection and provision apparatus 1 that has received the link information collection request, the link information collection and provision section 11 collects link information from a plurality of content provision apparatuses and stores it in the link information list storage section 12 as a link information list (step) 2).

  FIG. 6 shows an example of the link information list. As shown in FIG. 6, the link information list includes link information (URL) and explanatory text related to the link information (for example, content summary text), and these are in the format of a structured language such as HTML or XML. It is described in. When the link information list is displayed on the terminal device 4, each link information is displayed so that the link destination is accessed by clicking. Note that the case where there is one link information and one explanatory text is also called a link information list.

  Subsequently, based on the analysis rules stored in the analysis rule storage unit 15, the link information analysis unit 13 acquires the link destination content (web page) of the link information for each link information included in the link information list. In addition to analyzing information (HTML document or the like) constituting the content, information such as an image linked from the content is also acquired and analyzed based on the analysis rule as required (step 3).

  The processing by the link information analysis unit 13 will be described in more detail with reference to the flowchart of FIG.

  First, the link information analysis unit 13 acquires an analysis rule from the analysis rule storage unit 15 (step 21), and further acquires one link information from the link information list stored in the link information list storage unit 12 ( Step 22). The link information analysis unit 13 acquires content (here, it is assumed that it is an HTML document made up of text information) from the link destination of the link information (step 23), and the content is received by the terminal device 4 according to the analysis rule. It is determined whether or not it can be displayed (step 24).

  When it is determined that the content cannot be displayed on the terminal device 4, the link information (link information that cannot be displayed) and the reason why the content cannot be displayed are recorded in a storage unit such as a memory (step 25). In step 24, when it is determined that the target content can be displayed on the terminal device 4, and after step 25, it is checked whether the link information to be processed is the last link information in the link information list. (Step 26) If not the last, processing is performed on the next link information.

  If it is determined in step 26 that the link information is the last link information and the link information analysis unit 13 determines that there is no link information that cannot be displayed in the link information list (No in step 27), link information collection and provision The unit 11 performs processing for transmitting the link information list to the terminal device 4 (step 28 in FIG. 7 and step 4 in FIG. 4). In this transmission process, the link information list may be transmitted to the terminal device 4 at the time when there is a link information list request from the terminal device 4.

  In the terminal device 4, a link information list screen is displayed (step 5 in FIG. 4), and when specific link information (assumed to be link information of the content providing device 3) is selected from the screen, the link information is displayed. The content that is the link destination is transmitted from the content providing device 3 to the terminal device 4 (steps 6 and 7).

  On the other hand, when it is determined in step 27 of FIG. 7 that there is link-unavailable information in the link information list (Yes in step 27), the link information list transmission / reception unit 14 sends the link information list, non-displayable link information, Then, the reason why display is impossible is transmitted to the content conversion apparatus 2 (step 29 in FIG. 7 and step 10 in FIG. 5).

  As an analysis rule used in the above link information analysis processing, for example, a rule “if content includes a link to a file that uses application A for display, the content is determined not to be displayed”. There is. Since the “file using the application A” can be identified by the extension of the file name, as a specific analysis rule, the extension is stored in the analysis rule storage unit 12, and the link information analysis unit 13 analyzes the content to be analyzed. Then, it is checked whether or not a link to a file having the extension is described. If a link to a file having the extension is described, the link information analysis unit 13 determines that the content cannot be displayed on the terminal device 4 and stores the content in the storage unit. Link information to be displayed and the reason why display is impossible (information indicating “application A”, a number for identifying the analysis rule, etc.).

  Further, as an analysis rule, for example, a rule that “content size is less than X bytes” may be provided. In this case, for example, the link information analysis unit 13 obtains the size of the text information constituting the content as well as the size of the image linked from the content, and whether the total size is less than the size X defined by the rule. Judge whether. The link information analysis unit 13 determines that the content cannot be displayed on the terminal device 4 if the total size is equal to or larger than the size X determined by the rule, and the link information corresponding to the content and the reason why the display cannot be performed ("size" Information indicating “over”, a number for identifying the analysis rule, and the like) are recorded in the storage unit.

  “Application A” in the above analysis rule can be determined as an application that cannot be installed in the terminal device 4, and the X byte can be determined based on the memory capacity of the terminal device A. For example, when the terminal device 4 is a television that can be connected to the Internet, the analysis rule can be determined based on the standardized technical specifications of the television.

  The above analysis rule is an example, and any rule other than the above rule may be used as long as it can determine whether or not the content can be displayed. Further, by identifying a user by user login or the like, an analysis rule may be set for each user, and the analysis rule for each user may be used. Further, an analysis rule is set for each piece of identification information unique to the terminal device, and the link information collection and provision device 1 uses the unique identification information included in the request information received from the terminal device to deal with the terminal device. By adopting a configuration for discriminating the analysis rule, the analysis may be performed using the analysis rule for each terminal device.

  Next, the operation of the content conversion apparatus 2 will be described along the sequence chart of FIG.

  In step 10 of FIG. 5, in the content conversion device 2 that has received the link information list, the link information that cannot be displayed, and the reason why the display cannot be performed, the content conversion unit 22 performs a content conversion process (step 11). The content conversion process will be described with reference to the flowchart of FIG.

  The content conversion unit 22 acquires a conversion rule from the conversion rule storage unit 23 (step 31) and cannot display one piece of information (stored in a memory or the like) received from the link information collection / providing device 1 The link information and the reason for the display impossibility corresponding to the link information are acquired (step 32). Then, the link destination of the link information that cannot be displayed is accessed to acquire the content (referred to as an HTML document) (step 33).

  Subsequently, the content conversion unit 22 converts the acquired content based on the reason why the display is impossible and the conversion rule, and stores the converted content that is the converted content in the converted content storage unit 24 (step 34). The content conversion unit 22 performs the processing of step 32 to step 34 for each non-displayable link information (step 35).

  As a conversion rule, for example, when the reason why display is impossible is “application A”, content conversion is performed so that the terminal device 4 does not perform an acquisition operation on a file that requires the “application A” in the content. There is a rule. In this case, the content conversion unit 22 rewrites the description of the portion related to the file in the HTML document that is the content into a description for displaying the text “file cannot be displayed”.

  Further, as a conversion rule, there is a rule that content is divided when the reason why display is impossible is oversize.

  As a method of dividing the content, there is a method of dividing the content in order from the beginning so that each divided content is smaller than the size determined by the rule. In addition, when the HTML document is divided into frames, each frame is identified based on the description in the HTML document, the content is divided for each frame, and the size of each divided content is less than a predetermined size. It may be made to become. Moreover, based on the description content in an HTML document, you may divide | segment for every group of content. For example, an article and a comment on a blog page are divided.

  Further, instead of dividing the content, as a conversion rule, a rule may be provided in which the content is not displayed at all when the reason why display is impossible is “size over”. In this case, the corresponding link information in the link information list is rewritten with text information indicating that “content cannot be displayed”. In this case, the corresponding link information and description in the link information list may be deleted.

  After the content conversion is performed as described above, in step 12 of FIG. 5, the link information list rewriting unit 25 converts the non-displayable link information in the link information list into link information indicating the storage location of the converted content. rewrite. That is, the link information that cannot be displayed is rewritten to a URL indicating the converted content stored in the converted content storage unit 24. In this case, in order to be able to grasp the original URL, the description of the original URL may be left in a format that cannot be selected by the terminal device 4.

  Alternatively, when a rule that does not display non-displayable content is applied, the portion of the non-displayable link information is rewritten to text information indicating that display is not possible, and information indicating that display is not possible is the terminal device. 4 is displayed.

  Then, the link information list transmitting / receiving unit 21 transmits the rewritten link information list to the link information collection / providing device 1 (step 13), and the link information collection / providing device 1 transmits the link information list to the terminal device 4. (Step 14).

  The link information collection / providing device 1 may store the rewritten link information list in the link information list storage unit 12 and transmit the link information list to the terminal device 4 in response to a request from the terminal device 4. In this case, each time the user of the terminal device 4 desires to view the content described in the link information list, the user accesses the link information collection / providing device 1 and acquires / displays the link information list.

  In the terminal device 4, for example, when rewritten link information is selected, a content request is transmitted to the content conversion device 2, and the converted content is transmitted from the content conversion device 2 to the terminal device 4 (steps 15 and 16). .

(Other examples)
In the configuration example described above, the link information collection and provision unit 11 includes time information (× year × month × day) indicating the newness of the content corresponding to the explanatory text in each explanatory text in the link information list (FIG. 6). X hours x minutes x seconds). This time information includes the time when the link information corresponding to the explanatory text is collected, the time when the content corresponding to the link information is updated in the content providing apparatus, the time when the content corresponding to the explanatory text is released in the content providing apparatus, etc. However, time information other than these may be used.

  In this case, the link information analysis unit 13 checks the time information in each explanatory note in the link information list stored in the link information list storage unit 12 at a predetermined time interval, and the time at the time of the check (current It is checked whether a predetermined time has elapsed since the time indicated by the time information. Note that this time elapse determination may be performed by time determination means other than the link information analysis unit 13. In addition, the time information may be a specific time (× year × month × day × hour × minute × second) corresponding to the expiration date of the content. In this case, the link information analysis unit 13 Instead of determining whether or not a predetermined time has elapsed from the time indicated by, it is determined whether or not the current time has reached the specific time.

  If the time indicated by the time information in a description in the link information list has passed the predetermined time from the current time, the link information analysis unit 13 performs the process in step 3 of FIG. In the same manner as described above, link information analysis is performed on link information corresponding to the description (link information before rewriting when link information has been rewritten with content conversion). As a result of the analysis, if it is determined that the content display on the terminal device 4 is possible, the process waits until the next time interval is checked.

  As a result of the analysis, if it is determined that the content display is not possible, the same processing as Step 10 to Step 13 in FIG. 5 is executed. That is, the link information collection / providing device 1 sends the link information list, the link information determined to be incapable of content display, and the reason thereof to the content conversion device 2 (step 10 in FIG. 5). The content conversion device 2 performs content conversion (step 11) and link information rewrite (step 12), and returns the rewritten link information list to the link information collection and provision device 1 (step 13). In step 11 in this case, if there is already converted content, the previous converted content is invalidated and deleted from the converted content storage unit 24. In addition, when content conversion is performed here, the corresponding explanatory text may be updated.

  By performing such processing, even if the link information list includes link information of content that is frequently changed over time, such as a news article, the terminal device 4 can link. Each time the information collection / providing device 1 is accessed to acquire and display the link information list, the desired content can be appropriately displayed.

<Second Embodiment>
Next, a second embodiment of the present invention will be described focusing on differences from the first embodiment.

  The overall system configuration in the second embodiment is the same as that in the first embodiment, as shown in FIG.

  FIG. 9 shows the configuration of the link information collection and provision apparatus 1 in the second embodiment, and FIG. 10 shows the configuration of the content conversion apparatus 2 in the second embodiment. As shown in FIGS. 9 and 10, in the present embodiment, the link information collection and provision apparatus 1 does not include the link information analysis unit 13 and the analysis rule storage unit 15, but includes the link information analysis unit 13 and the analysis rule storage unit 15. The content conversion device 2 is different from the first embodiment. The processing operation of the link information analysis unit 13 itself and the rules stored in the analysis rule storage unit 15 are the same as those in the first embodiment.

  Next, the operation of the system in the second embodiment will be described with reference to the sequence charts of FIGS.

  As shown in FIG. 11, first, the link information collection and provision apparatus 1 receives a link information collection request from the terminal apparatus 4 (step 41). In the link information collection and provision apparatus 1 that has received the link information collection request, the link information collection and provision section 11 collects link information from a plurality of content provision apparatuses and stores it in the link information list storage section 12 as a link information list (step) 42). In the second embodiment, the link information list transmission / reception unit 14 transmits the link information list stored in the link information list storage unit 12 to the content conversion device 2 without analyzing the link information (step 43). .

  In the content conversion device 2 that has received the link information list, the link information analysis unit 13 sets the link destination of the link information for each link information included in the link information list based on the analysis rules stored in the analysis rule storage unit 15. Content (web page) is acquired, and the information (HTML document, etc.) constituting the content is analyzed, and information such as images linked from the content is also acquired and analyzed as necessary based on the analysis rules (Step 44). The analysis process here is the same as that described in step 21 to step 27 of FIG.

  As a result of the analysis, if it is determined that there is no undisplayable link information in the link information list, the link information list transmission / reception unit 21 transmits the received link information list to the link information collection / providing device 1. Or you may transmit the information which shows that there is no link information which cannot be displayed to the link information collection provision apparatus 1 (step 45 of FIG. 11). And the link information collection provision part 11 transmits the said link information list to the terminal device 4 (step 46).

  In the terminal device 4, a link information list screen is displayed (step 47), and when specific link information (assumed to be link information of the content providing device 3) is selected from the screen, a link destination of the link information Is transmitted from the content providing apparatus 3 to the terminal apparatus 4 (steps 48 and 49).

  On the other hand, when it is determined in step 44 of FIG. 11 that there is undisplayable link information in the link information list, the link information analysis unit 13 converts the link information list, the non-displayable link information, and the non-displayable reason into content conversion. The unit 22 is notified (step 51 in FIG. 12).

  The content conversion unit 22 that has received the link information list, the non-displayable link information, and the non-displayable reason performs content conversion processing (step 52). The content conversion process is the same as in the first embodiment.

  After the content conversion is performed, in step 53 of FIG. 12, the link information list rewriting unit 25 rewrites the non-displayable link information in the link information list to the link information indicating the storage location of the converted content. That is, the link information that cannot be displayed is rewritten to a URL indicating the converted content stored in the converted content storage unit 24. Alternatively, when a rule that does not display non-displayable content is applied, the portion of the non-displayable link information is rewritten to text information indicating that display is not possible, and information indicating that display is not possible is the terminal device. 4 is displayed.

  Then, the link information list transmission / reception unit 21 transmits the rewritten link information list to the link information collection / providing device 1 (step 54), and the link information collection / providing device 1 transmits the link information list to the terminal device 4. (Step 55).

  The link information collection / providing device 1 may store the rewritten link information list in the link information list storage unit 12 and transmit the link information list to the terminal device 4 in response to a request from the terminal device 4.
