  The matching processing unit 60 extracts category information associated with the user information from the category DB 58 (S83). Here, when the corresponding category cannot be extracted in the matching processing unit 60, the content is extracted from the content DB 59 based on the distribution priority, and is output to the advertisement / recommendation distribution unit 61 (S85). When the matching processing unit 60 extracts the corresponding category, the content included in the extracted category is extracted from the content DB 59 and output to the advertisement / recommendation distribution unit 61 (S86). Next, the advertisement / recommendation distribution unit 61 distributes the content to the mobile terminal or the information home appliance (S87). Here, the advertisement / recommendation distribution unit 61 may estimate the time that the user is in the home from the operation history of the information home appliance 10 and distribute the content at the estimated time. Next, the advertisement / recommendation receiving unit 17 of the information home appliance 10 receives the content and outputs it to the advertisement / recommendation display unit 18 (S88). Next, the advertisement / recommendation display unit 18 displays the received content on the display 19 (S89). Similarly, the mobile terminal 20 displays the received content on the display.

  Here, the category DB 58 includes category information, a category similar word for classifying into the same category, a user ID for specifying a user, and the like. In addition, the content DB 59 includes a content type, a content name, a content ID, content data, a distribution priority used at the time of distribution, and the like.

  As described above, the distribution server 50 according to the first embodiment of the present invention can generate the preference information using the operation history of the information home appliance when the user is at home. Furthermore, the distribution server 50 can generate preference information using the user's search history. Thereby, even in a situation where the number of operations of the mobile terminal by the user is reduced, such as when the user is in the house, the operation history is collected from the information home appliance 10 operated in the user's daily life, and the preference information Can be generated. As a result, using the preference information generated from the search history of the user's mobile terminal and the preference information generated from the operation history of the information home appliance 10, the category of advertisement and recommendation information that matches the user's preference Can be generated.

  In addition, since the operation history of the information home appliance 10 is automatically accumulated by home appliance operations performed by the user in normal life, user preference information can be generated without the user being aware of it.

  Note that the present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
