[Operation example]
FIG. 7 shows a processing flow of content display processing according to the present invention.

  First, in the user terminal 1, a content display program having a function of displaying a website on the Internet is started. The content display program causes the user terminal 1 which is the computer shown in FIG. 5 to function as the apparatus shown in FIG.

  In step S <b> 1 of FIG. 7, the biological information acquisition unit 11 of the user terminal 1 cooperates with an input device such as a microphone and a camera connected to the user terminal 1 to capture voice data including the user's voice and the user's face. The biometric information such as the image or video data that has been recorded is acquired, and the acquired biometric information is stored in the data storage unit 15. Here, the user inputs voice to the browser software via the microphone. For example, a greeting is given in a language (such as a native language) used by the user, or the start of processing is instructed. The camera takes a picture of a user who operates the user terminal 1. Although the camera can also acquire moving image data, in the present embodiment, description will be made assuming that still image data is acquired at a predetermined timing.

  In step S <b> 2, the attribute information acquisition unit 12 of the user terminal 1 acquires user attribute information using the user biometric information stored in the data storage unit 15. Here, first, the attribute information acquisition unit 12 reads the biometric information stored in the data storage unit 15 and transmits it to the attribute analysis device 2 via the communication IF. Note that the processing of steps S1 (particularly image acquisition) and S2 is continuously performed by the user terminal 1.

  On the other hand, the reception unit 21 of the attribute analysis apparatus 2 receives the biological information and stores it in the data storage unit 24. And the attribute analysis part 22 analyzes the biometric information stored in the data storage part 24, and specifies a user's attribute. The identified attribute is stored in the data storage unit 24 as attribute information indicating the user's attribute.

  The analysis is performed using, for example, a known pattern recognition technique. Specifically, a user attribute is determined by extracting a feature value (feature vector) from the user's voice data or image data and specifying a group (cluster) to which the feature value belongs.

The user attributes include items such as sex, age category, and language used, and the attribute information is represented by parameters as shown below, for example.
{Gender} & {Age category} & {Language}
{Gender} contains information indicating “male” or “female”. For {age category}, for example, “6-9 years old”, “10-12 years old”, “13-15 years old”, “16-18 years old”, “19-22 years old”, “22-29 years old”, Information indicating a classification such as “30-39 years old”, “40-49 years old”, “50 years old or older” is entered. In {Language}, information indicating "Japanese", "Korean", "Chinese", "French", "German", "Spanish", "Russian", "English", etc. Enters. The gender and age category are specified based on at least one of the user's voice data or image data, and the language used is specified based on the user's voice (for example, a greeting made by the user).

  Then, the transmission unit 23 reads the attribute information from the data storage unit 24 and transmits it to the user terminal 1. The attribute information acquisition unit 12 of the user terminal 1 receives the attribute information in cooperation with the communication IF and stores the attribute information in the data storage unit 15.

In step S <b> 3, the content acquisition unit 13 of the user terminal 1 receives a content display request from the user, and transmits the received content display request and attribute information read from the data storage unit 15 to the distribution control server 3. Here, first, a content display request is received from the user via an input device such as a keyboard, a mouse, or a touch panel connected to the user terminal 1. For example, as a content display request, the user inputs a URI (Uniform Resource Identifier) of a website to be displayed, or selects a link to another website included in the website. Then, the content acquisition unit 13 transmits the received content display request and the user attribute information stored in the data storage unit 15 to the distribution control server 3 via the communication IF.

  After the content acquisition unit 13 accepts the content display request, the biometric information acquisition unit 11 performs step S1, the attribute information acquisition unit 12 performs step S2, and the content acquisition unit 13 performs the content display request and the attribute. Information may be transmitted to the distribution control server 3.

  Thereafter, the process proceeds to step S11 in FIG. FIG. 8 shows a processing flow of content distribution processing by the distribution control server 3.

  In step S <b> 11 of FIG. 8, the receiving unit 31 of the distribution control server 3 receives the content display request and attribute information from the user terminal 1 and stores them in the data storage unit 36.

  In step S12, the content acquisition unit 32 reads a content display request from the data storage unit 36, and acquires content data on the network. Here, for example, hypertext is received from a Web server on the Internet based on the URI.

  In step S13, first, the conversion control unit 34 reads out the attribute information stored in the data storage unit 36 and refers to the conversion control table 33, and the age category of the user in the read out attribute information performs a filtering process. Judge whether it falls under the target. Here, the filtering process refers to a process of blocking (blocking) access to content, for example. Further, as the filtering process, a process of blocking the writing may be performed for the content having a function such as a bulletin board and the content that should be blocked from being written.

  FIG. 9 is a diagram illustrating an example of a data configuration of the conversion control table 33. In the conversion control table 33, for example, conversion processing relating to “(character / image) size”, “assignment name”, “keyword”, “image”, and “filtering” is performed in association with information indicating “age category”. It is assumed that information indicating whether or not is stored. In the example of FIG. 9, “◯” is stored as information indicating that the processing is to be performed, and “−” is stored as information indicating that the processing is not performed.

  When it is determined that the age category of the attribute information is the target of filtering processing (that is, “○” is stored in the item value of “filtering” in association with the information indicating the age category of the received attribute information) The conversion control unit 34 transmits the URI and the attribute information of the content data stored in the data storage unit 36 to the conversion device 4a. It should be noted that only the information indicating the age classification among the attribute information may be read and transmitted.

  On the other hand, the receiving unit 41a of the conversion device 4a receives the URI and attribute information of the content data from the distribution control server 3, and stores them in the data storage unit 45a. Then, it is determined whether the URI of the content data is included in the black list of the conversion table 42a.

  FIG. 10 is a diagram illustrating an example of a data configuration of the conversion table 42a. For example, it is assumed that the conversion table 42a stores a black list of websites whose display should be filtered in association with age categories. When the URI of the content data is included in the blacklist, the transmission unit 44a transmits information (for example, a flag) indicating whether or not the content data should be filtered to the distribution control server 3. When a domain name (for example, up to a subdomain) is registered in the black list and the URI of the content data includes the domain name, it may be determined that the URI of the content data is included in the black list. Good.

  The receiving unit 31 of the distribution control server 3 receives information indicating whether or not the content data should be filtered from the conversion device 4 a and stores it in the data storage unit 36. In addition, when the distribution control server 3 receives information indicating that the content data should be filtered, the processing from the subsequent steps S14 to S18 may be omitted.

  In step S14, the conversion control unit 34 transmits the content data and attribute information stored in the data storage unit 36 to the conversion device 4b and receives the translated content data from the conversion device 4b. Here, the conversion control unit 34 first reads content data and attribute information from the data storage unit 36 and transmits the content data and attribute information to the conversion device 4 b via the transmission unit 35. As attribute information, only information indicating a language used may be read and transmitted.

  Further, the conversion control unit 34 determines whether or not the user's language used in the attribute information stored in the data storage unit 36 is the same as the language used for the description of the content data. You may make it transmit data and attribute information to the converter 4b. The language used for describing the content data is determined based on, for example, an HTML meta tag indicating a character code. When it is determined that the language used for the received attribute information is different from the language used for describing the content data, the conversion control unit 34 converts the content data and attribute information stored in the data storage unit 36. The data is transmitted to the device 4b.

  On the other hand, the receiving unit 41b receives content data and attribute information from the distribution control server 3, and stores them in the data storage unit 45b. The conversion table 42b of the conversion device 4b stores dictionary data not shown for use in machine translation. Then, the conversion unit 43b performs content data translation processing using the dictionary data stored in the conversion table 42b. Note that a known machine translation technique can be used for the translation process, and it is possible to determine in which language the content data before translation is described. Then, the conversion unit 43b machine translates the received content data into the language used for the received attribute information, and the transmission unit 44b transmits the translated content data to the distribution control server 3.

  The receiving unit 31 of the distribution control server 3 receives the translated content data from the conversion device 4 b and stores it in the data storage unit 36.

In step S15, first, the conversion control unit 34 refers to the conversion control table 33, and whether or not the age category of the attribute information stored in the data storage unit 36 corresponds to a target for changing the character size and image size. Judge. In the conversion control table 33, when “◯” is registered in the item of character size and image size in association with the age category of the attribute information, the conversion control unit 34 stores the attribute information stored in the data storage unit 36. Is transmitted to the conversion device 4c. In the example of FIG. 9, all age categories are set as targets for changing the character size and image size. As attribute information, only information indicating the age category may be read and transmitted.

  On the other hand, the receiving unit 41c receives the attribute information from the distribution control server 3 and stores it in the data storage unit 45c. Then, the conversion unit 43c reads the character size value (ratio) and the image size value (ratio) from the conversion table 42c using the age classification of the attribute information stored in the data storage unit 45c.

  FIG. 11 is a diagram illustrating an example of a data configuration of the conversion table 42c. In the conversion table 42c, for example, it is assumed that a character size value (ratio) and an image size value (ratio) are stored in association with information indicating an age category.

  Then, in the conversion unit 43 c, the transmission unit 44 transmits the read character size value and image size value to the distribution control server 3.

  The receiving unit 31 of the distribution control server 3 receives the character size value and the image size value from the conversion device 4 c and stores them in the data storage unit 36.

  In step S16, the distribution control server 3 receives a list of combinations of kanji and kana included in the content data as kana conversion information. In this step, first, the conversion control unit 34 refers to the conversion control table 33 and determines whether or not the age classification of the attribute information stored in the data storage unit 36 corresponds to a target to which a kana is assigned. When it is determined that the age classification of the attribute information is the target to which the kana is added, the conversion control unit 34 stores the content data stored in the data storage unit 36 (when the translated content data is acquired in step S14). Transmits the translated content data) and attribute information to the conversion device 4d. As attribute information, only information indicating the age category may be read and transmitted. Further, the processing of this step may be performed only when the information indicating the language used in the attribute information indicates “Japanese”.

  On the other hand, the receiving unit 41d receives content data and attribute information from the distribution control server 3 and stores them in the data storage unit 45d. Next, the conversion unit 43d decomposes the received content data into words using, for example, a known morphological analysis technique. Then, among the decomposed words, those registered in the conversion table 42d in association with the age category of the attribute information are extracted.

  FIG. 12 is a diagram illustrating an example of a data configuration of the conversion table 42d. In the conversion table 42d, for example, it is assumed that a list of kanji characters to which a kana character is to be added and a combination of the kana characters is stored in association with the age category.

  Then, the converting unit 43d extracts combinations of kanji characters included in the content data that are registered in association with the received age category and their kana characters, and stores them as a list of kanji and kana characters combinations. Stored in the unit 45d. Thereafter, the transmission unit 44d reads a list of combinations of kanji and kana from the data storage unit 45d and transmits the list to the distribution control server 3.

  The receiving unit 31 of the distribution control server 3 receives a list of combinations of kanji and kana from the conversion device 4 d and stores the list in the data storage unit 36.

  In step S17, the distribution control server 3 acquires a keyword to be masked included in the content data as keyword conversion information. First, the conversion control unit 34 refers to the conversion control table 33 and determines whether or not the age classification of the attribute information stored in the data storage unit 36 corresponds to a target for keyword mask processing. Here, keyword mask processing refers to processing that makes a keyword unreadable by replacing or deleting the keyword with an arbitrary character string such as a blank or a meaningless symbol, for example. And

  When it is determined that the age category of the attribute information is a target for keyword masking, the conversion control unit 34 transmits the content data and attribute information stored in the data storage unit 36 to the conversion device 4e. Note that only the information indicating the age category and sex may be read out and transmitted from the attribute information.

  On the other hand, the receiving unit 41e receives content data and attribute information from the distribution control server 3, and stores them in the data storage unit 45e. Next, the conversion unit 43e decomposes the received content data into words using, for example, a known morphological analysis technique. Then, it is determined whether each decomposed word is associated with the age category and sex information and registered in the conversion table 42e.

  FIG. 13 is a diagram illustrating an example of a data configuration of the conversion table 42e. In the conversion table 42e, for example, it is assumed that a list of keywords to be masked is stored in association with age categories and sexes. A keyword may be registered for each language used.

  Then, the conversion unit 43e extracts the words registered in the conversion table 42e in association with the received age category and sex, and stores them in the data storage unit 45e as a list of keywords to be masked. To do. Thereafter, the transmission unit 44e reads out a list of keywords to be masked from the data storage unit 45e and transmits the list to the distribution control server 3.

  The receiving unit 31 of the distribution control server 3 receives a list of keywords to be masked from the conversion device 4 e and stores it in the data storage unit 36.

  In step S18, the distribution control server 3 acquires an image to be masked included in the content data as the image conversion information. First, the conversion control unit 34 refers to the conversion control table 33 and determines whether or not the age classification of the attribute information stored in the data storage unit 36 corresponds to the target for image masking. The image masking process refers to a process in which an image is not displayed, for example, by replacing or deleting the image with a blank or a solid color image.

  If it is determined that the user's age category is a target for image masking, the conversion control unit 34 transmits the content data and attribute information stored in the data storage unit 36 to the conversion device 4f. In addition, about attribute information, only the information which shows an age division and sex may be read and transmitted.

  On the other hand, the receiving unit 41f receives content data and attribute information from the distribution control server 3, and stores them in the data storage unit 45f. Next, the conversion unit 43f extracts an image (for example, an IMG tag in HTML) from the content data, for example. Then, it is determined whether or not the extracted image matches the condition of the image to be masked that is associated with the age category and sex information of the user and registered in the conversion table 42f.

  FIG. 14 is a diagram illustrating an example of a data configuration of the conversion table 42f. For example, it is assumed that the conversion table 42f stores information indicating the conditions of an image to be masked in association with the age category and sex. When the image included in the content data satisfies the condition, it is determined that the image is an image to be masked. A known filtering technique can be used for determining whether the image is to be masked and for masking. For example, using a known pattern recognition technique, it is determined whether or not an image feature value (feature vector) included in the content data is included in a group (cluster) of images to be masked.

  Then, the conversion unit 43f extracts images to be masked from the images included in the content data, and stores them in the data storage unit 45f as a list of images to be masked. Here, for example, a list of IMG tags is stored. Thereafter, the transmission unit 44f reads a list of images to be masked from the data storage unit 45f and transmits the list to the distribution control server 3.

  The receiving unit 31 of the distribution control server 3 receives a list of images to be masked from the conversion device 4 f and stores the list in the data storage unit 36.

  Note that the processing of steps S13 to S18 in FIG. 8 can be performed in an arbitrary order. Further, the processes of steps S13 to S18 may be performed in parallel, or only a part of the processes of steps S13 to S18 may be performed.

  In step S19, the conversion processing unit 34 of the distribution control server 3 stores the character size value and image size conversion information, a list of combinations of kanji and kana, and keywords to be masked, which are stored in the data storage unit 36. Content conversion processing is performed using the list, the list of images to be masked, information indicating whether or not the content data should be filtered, and the translated content data, and the converted content data is stored in the data storage unit 36.

  Specifically, first, it is determined whether or not to display content data based on information indicating whether or not the content data should be filtered. When filtering the display of the content data itself, for example, predetermined content data prepared in advance is stored as the converted content data. Also, when the content to be filtered corresponds to the content to be blocked, for example, the text box is deleted from the content data and converted so that the writing can be restricted.

  In addition, as a process of converting the character size and the image size, a CSS for changing the size is generated using the character size value and the image size value stored in the data storage unit 36.

  When the translated content data exists in the data storage unit 36, the character string included in the content data is replaced with the translated character string of the content data.

  If there is a combination of kanji and hiragana, for example, an HTML RUBY tag is used, or a kana is added to the content data using CSS.

If there is a keyword to be masked, the corresponding keyword is replaced with, for example, an arbitrary character string. Note that the entire sentence or the entire paragraph including the keyword to be masked may be deleted or replaced. When there is an image to be masked, for example, an IMG tag for displaying the image is replaced in the content data so that, for example, an image filled with a blank or a single color is displayed.

  The conversion processing unit 34 performs the conversion processing as described above, generates converted content data, and stores it in the data storage unit 36.

  In step S <b> 20, the transmission unit 35 transmits the converted content data (for example, HTML data and CSS data) from the data storage unit 36 to the user terminal 1. Thereafter, the process proceeds to step S4 in FIG.

  In step S <b> 4 of FIG. 7, the content acquisition unit 13 of the user terminal 1 receives the converted content data from the distribution control server 3 and stores it in the data storage unit 15.

  In step S <b> 5, the content display control unit 14 displays the converted content data stored in the data storage unit 15 on a display device connected to the user terminal 1.

  In step S6, the attribute information acquisition unit 12 acquires user image or sound data and attribute information based on these data. The processing in step S6 is to continuously perform the same processing as in steps S1 and S2 at a predetermined cycle or arbitrary timing. For the convenience of explanation, the steps are ordered, but it is assumed that the process of step S6 is continuously performed independently of the processes of steps S3 to S5.

  In step S7, the content display control unit 14 compares the attribute information newly acquired in step S6 with the previous attribute information acquired in the previous time and stored in the data storage unit 15, and the attribute information has changed. Determine whether or not.

  For example, when the user operating the user terminal 1 is changed to another user and the age category or gender specified based on the user's image changes, it is determined that the attribute information has changed. Further, the user's voice may be acquired and it may be determined that the attribute information has changed when the language used has changed. When the newly acquired attribute information changes, the attribute information acquisition unit 12 stores the newly acquired attribute information in the data storage unit 15.

  If it is determined that the attribute information has not changed (S7: No), the process proceeds to step S9. On the other hand, when it is determined that the attribute information has changed (S7: Yes), the content display control unit 14 transitions to the process of step S8.

  In step S8, the content data displayed on the display device is changed to non-display, for example. This can stop the display of content data that may be inappropriate for new users with different attributes. In addition to changing the display of content data, if the content display program holds information such as content display history and bookmarks in the data storage unit 15, the information is deleted from the data storage unit 15. It may be. Further, for example, cookie information that tracks user behavior may be deleted.

  Note that, for example, when it is determined that the user is not captured in the image data due to the user leaving the seat or the like, it may be determined that the user attribute information has changed. In addition, even when another user approaches the user terminal 1 and it is determined that a plurality of users are captured in the image data, it may be determined that the user attribute information has changed.

The content data may be hidden and switched to a predetermined screen (a predetermined screen is displayed). Further, the content display request is transmitted again to the distribution control server 3 using the newly acquired attribute information and the content display request received in step S3, and the content is converted again based on the newly acquired attribute information. Data may be received from the distribution control server 3 and the display of content data may be updated. In this way, for example, when a keyword to be masked for a new user is included in the content data, the keyword that is a part of the content data is masked and the display is updated. In addition, for example, the use of content data is limited as in the case of a mask. In some cases, the size of characters is changed to a size that is easy to read, or a kana is assigned to kanji.

  Then, the process proceeds to step S9.

  In step S9, the content acquisition unit 13 determines whether a new content display request is input from the user. If it is determined that no content display request has been input (S9: No), the process returns to step S6. On the other hand, if it is determined that a content display request has been input (S9: Yes), the process returns to step S3.

  By performing the process as described above, the content to be displayed can be converted according to the attribute information specified based on the user's biometric information without performing the user authentication process. The conversion is performed by applying a preset conversion rule using, for example, a proxy server. Therefore, it is not necessary to create a website to be displayed in accordance with the attribute information in advance, and content data converted according to the user's attribute can be provided.

  Also, by converting the content, it becomes possible to appropriately limit the use of the content according to the user's attributes and improve the usability of the content.

  For example, if adult content or violent content is filtered for younger users, parents can use their terminals with peace of mind. In addition, by using ruby for kanji characters that are not learned at school, the content can be easily used by younger users. For older users, the text can be read easily by enlarging the characters and images included in the content. Furthermore, for example, when a link is made from a character or an image and the character or image is clickable, the operability is improved by making the character or image enlarged (easier to click). Moreover, if content described in a language different from the language used by the user is automatically translated and provided, the usability of the content is improved.

  Further, in the present embodiment, authentication processing / cancellation processing for each user such as login / logout is not performed. Therefore, the content data already displayed on the display device may not be appropriate for a user who has newly started using the terminal device. Even in such a case, it is not appropriate for the new user attribute information by continuously monitoring the user attribute information and changing the displayed content data when there is a change. The display of content data can be stopped.

[Modification]
In the embodiment described above, when the user attribute changes, the content data is hidden or the display of the content data is updated. However, some content data does not include keywords or images that should be masked for users with other attributes, and there is no need to stop (block) display for users with other attributes. Such content data need not be hidden.

  Therefore, in this modification, the display control information indicating that the content data displayed on the user terminal 1 includes content to be blocked for a user having an attribute other than the attribute indicated by the current user's attribute information. By using this, it is possible to determine whether or not to change the display of content data for users having different attributes. For example, in steps S13, S17, and S18 (FIG. 8), the distribution control server 3 selects content to be blocked for users having attributes other than the attributes indicated by the attribute information, based on the received attribute information and content data. Whether or not the content data is included is determined by each conversion device, and if it is included, the display control information is transmitted to the user terminal 1 in step S20. In step S4 (FIG. 7), when the user terminal 1 receives the display control information from the distribution control server 3 and receives the information (for a user having an attribute other than the attribute indicated by the attribute information of the current user) Only when the content to be blocked is included), the display is changed in step S8. Here, the content to be blocked refers to content including a keyword or image to be masked or content to be filtered, for example.

  Specifically, in step S13 (FIG. 8), the conversion unit 43a of the conversion device 4a searches the conversion table 42a, and the URI of the received content data is filtered for the received age category and gender users. For a user who does not fall under the target and who has received the age category and gender, a process of determining whether the user falls under the filtering target is further performed. When it is determined that such a condition is satisfied, the content data includes display control information indicating that the content data should include a content to be blocked for a user having an attribute other than the attribute indicated by the current user's attribute information. The conversion device 4a transmits to the distribution control server 3.

  Similarly, in step S17, the conversion unit 43e of the conversion device 4e searches the conversion table 42e, and includes words that are included in the received content data and should be masked against the received age category and gender users. Although it is not registered as, a process for extracting those registered as keywords to be masked for users other than the received age category and gender is further performed. When the corresponding word is extracted, the content data includes display control information indicating that the content data should be blocked for a user having an attribute other than the attribute indicated by the current user's attribute information. 4e transmits to the distribution control server 3.

  In step S18, the conversion unit 43f of the conversion device 4f searches the conversion table 42f, and includes an image included in the received content data, which is an image to be masked for the received age category and gender user. Although it does not correspond to the condition, a process for extracting a user other than the received age category and gender that satisfies the condition of the image to be masked is further performed. When the image is extracted, the conversion device 4f displays display control information indicating that the content data includes content to be blocked for a user having an attribute other than the attribute indicated by the current user's attribute information. Transmit to the distribution control server 3.

When the distribution control server 3 receives the display control information from the conversion device 4, based on the content data and the attribute information, the converted content data is sent to the user having an attribute other than the attribute indicated by the received attribute information. It turns out that it was determined that the content to be blocked was included. In other words, the distribution control server 3 uses the conversion device 4 to convert the content data converted based on the received attribute information based on attribute information of an attribute other than the attribute indicated by the received attribute information. In addition, it is determined whether or not a portion (content) to be changed is included. Such determination may be performed by, for example, the conversion control unit 34 in FIG. 4 or may be performed by a determination unit that is not illustrated. When the display control information is received from any of the conversion devices 4, the transmission unit 35 of the distribution control server 3 transmits the display control information to the user terminal 1 in step S20.

  Then, the user terminal 1 changes the display in step S8 only when the display control information is received in step S4 (FIG. 7). In this way, when it is determined that the attribute of the user who uses the user terminal 1 has changed, the display may be changed to content data that does not need to be blocked for a user with any attribute. Disappear. That is, content display control can be performed more appropriately. It should be noted that the display control information includes information specifically indicating to which age category or gender the display should be restricted, and the user terminal 1 detects the corresponding age category or gender attribute information. Only in such a case, the display of the content data may be changed.

  Moreover, the biological information shown in the embodiment is an example, and user attribute information may be specified from other information. Moreover, you may make it use either the audio | voice data mentioned by embodiment, or image data. However, if the attribute information is specified based on the feature values of both, it can be expected that the accuracy of the specified result is improved.

  Further, the user terminal 1 may have the attribute analysis unit 22 of the attribute analysis device 2. In this way, it is not necessary to transmit / receive biometric information and attribute information via the network. Of the functions of the attribute analysis unit 22, the user terminal 1 may perform a process of extracting a feature value from the biological information. In this way, since the user terminal 1 has only to transmit the feature value to the attribute analysis device 2, the amount of information to be transmitted is reduced. In addition, it can be expected that the number of users who feel resistance is reduced as compared to the case where their own biological information is exchanged as it is. On the other hand, in the embodiment described above, by using the external attribute analysis apparatus 2, the content display program of the user terminal 1 does not need to perform complicated processing.

  Further, the distribution control server 3 may use only some of the conversion devices among the conversion devices 4a to 4f. That is, only a part of the processes in steps S13 to S18 may be performed, and the content conversion process of step S19 may be performed based on this. Further, processing different from the exemplified content conversion processing may be further performed. For example, a conversion device 4 that prepares a table for registering advertisement information in association with attribute information and extracts and transmits advertisement information to be added to content data when content data and attribute information are received is used. You may do it. Furthermore, for example, the distribution control server 3 may perform part or all of the processing (steps S13 to S18) of the conversion devices 4a to 4f. Further, the distribution control server 3 may transmit the URI of the content data instead of the acquired content data to the conversion devices 4a to 4f, and the conversion devices 4a to 4f may acquire the content data respectively.
