There is a possibility that the effort may increase in the case of publishing, and there is a problem that the setting of the rating level may be mistaken for 3).

  In the present invention, the above-mentioned problem is solved by adding rating information to an HTML file in a transfer device installed between a home server and an external client.

  Hereinafter, features of the rating system according to the present invention will be described. In the rating system according to the present invention, a transfer device for transferring an HTML file to an external client is provided between a home server (such as a personal home server) that transmits the HTML file and an external client that receives the HTML file. It is arranged.

  When an HTTP (Hyper Text Transfer Protocol) request for acquiring the content of the home server is transmitted from the external client, the home server sends an HTTP response including a screen (HTML file) in which the rating information does not exist to the external client. Send back.

  A transfer device represented by a router or the like monitors an HTTP response from a home server, and when receiving an HTTP response, acquires the HTTP response and performs a keyword search on the BODY portion of the HTTP response.

  The transfer device creates an HTML file to which rating information based on keyword search is added, and transmits an HTTP response including the HTML file to the external client. Keywords and rating information corresponding to the keywords are set in advance.

  Even when an HTTP response including rating information is received, the transfer device can notify the external client of correct rating information by overwriting the rating information.

  The present invention obtains an HTTP response transmitted by a home server in response to an HTTP request from the outside, performs keyword search on the BODY portion of the HTTP response with a keyword set in advance, and adds rating information to HTML By transferring the HTTP response including the file to the external client, the rating can be automatically performed.

  FIG. 1 is a block diagram showing a configuration example of a transfer apparatus according to the first embodiment of the present invention. In FIG. 1, the transfer device 1 includes an HTTP response monitoring unit 11, a BODY acquisition unit 12, a keyword search unit 13, a keyword storage unit 14, a rating table 15, a rating analysis unit 16, and an HTTP response generation unit 17. And an HTTP response transmission unit 18.

  The HTTP response monitoring unit 11 monitors a received packet from a home server (not shown) in the transfer device 1 and acquires an HTTP response when an HTTP response is detected. The BODY acquisition unit 12 acquires the BODY unit from the HTTP response acquired by the HTTP response monitoring unit 11. The keyword search unit 13 searches for a keyword in the BODY unit acquired by the BODY acquisition unit 12.

  The keyword storage unit 14 stores keywords set in advance by the user. The rating table 15 stores keywords and rating levels that are set in advance by the user in association with each other.

  The rating analysis unit 16 compares the search result of the keyword search unit 13 with the rating table 15 and determines the rating level. The HTTP response generation unit 17 generates an HTTP response by adding the rating level information determined by the rating analysis unit 16 to the BODY unit. The HTTP response transmission unit 18 transmits the HTTP response generated by the HTTP response generation unit 17 to an external client (not shown).

  FIG. 2 is a diagram showing a configuration example of the rating table 15 of FIG. In FIG. 2, the rating table 15 includes keywords (“AAAA”, “BBBB”, “CCCC”, “DDDD”, “EEEE”,..., “XXXX”) set in advance by the user, and rating levels ( “2”, “3”, “7”, “5”, “1”,..., “6”).

  FIG. 3 is a sequence chart showing an operation example of the rating system according to the first embodiment of the present invention. The operation of the rating system according to the first embodiment of the present invention will be described with reference to FIGS.

  When the HTTP response monitoring unit 11 monitors the packet transmitted from the home server 2 and receives an HTTP response [response to the HTTP request from the external client 3] from the home server 2 (a1, FIG. a2) The HTTP response monitoring unit 11 acquires an HTTP response packet and notifies the BODY acquisition unit 12 of the HTTP response packet.

  The BODY acquisition unit 12 extracts HTML from the notified packet and notifies the keyword search unit 13 of the HTML. The keyword search unit 13 acquires a keyword from the keyword storage unit 14 that stores a keyword set in advance by the user, searches whether the keyword exists in the HTML extracted by the BODY acquisition unit 12, and obtains the keyword search result. The rating analysis unit 16 is notified.

  The rating analysis unit 16 determines the obtained HTML rating level based on the keyword search result in the keyword search unit 13 and the rating table 15, and notifies the determined rating level to the HTTP response generation unit 17.

  The HTTP response generation unit 17 generates an HTTP response including HTML added with the rating level notified from the rating analysis unit 16 (a3 in FIG. 3), and notifies the HTTP response transmission unit 18 of the generated HTTP response.

  The HTTP response transmission unit 18 transmits an HTTP response including the rated HTML (HTML to which the rating level is added) to the external client 3 (a4 in FIG. 3).

  As shown in FIG. 2, the keyword and the rating level are set in advance and stored in the keyword storage unit 14 and the rating table 15, respectively.

  FIG. 4 is a flowchart showing a keyword and rating table 15 creation process in the transfer apparatus 1 of FIG. 1, and FIG. 5 is a flowchart showing an operation until a rating level is added in the transfer apparatus 1 of FIG.

  The transfer apparatus 1 monitors the received packet from the home server 2 by the HTTP response monitoring unit 11 (step S11 in FIG. 5), and when receiving the received packet, determines whether the packet is an HTTP response (FIG. 5). Step S12).

  If it is not an HTTP response, the transfer device 1 does not acquire the packet in the transfer device 1 and transfers it to the external client 3 or the like as it is (step S19 in FIG. 5). When the transfer apparatus 1 receives the HTTP response, the BODY acquisition unit 12 acquires the BODY part from the HTTP response (step S13 in FIG. 5).

  Subsequently, the transfer apparatus 1 acquires HTML from the BODY unit in the BODY acquisition unit 12 (step S14 in FIG. 5), and the keyword search unit 13 determines whether or not a keyword set in advance by the user exists in the acquired HTML. (Step S15 in FIG. 5).

  In the transfer device 1, the rating analysis unit 16 compares the keyword search result of the keyword search unit 13 with the rating table 15 and determines the HTML rating level (step S16 in FIG. 5).

  The transfer apparatus 1 generates an HTTP response in which the rating level determined by the rating analysis unit 16 is added to HTML by the HTTP response generation unit 17 (step S17 in FIG. 5), and generates the generated HTTP response from the HTTP response transmission unit 18 to the outside. The data is transmitted to the client 3 (step S18 in FIG. 5).

  Thus, in this embodiment, since rating information is added in the transfer apparatus 1 to the content (HTML file) from the home server 2, it is possible to prevent the user from forgetting to add rating information.

  Further, in the present embodiment, even when there are a lot of contents in the home server 2, since the rating information is added in the transfer device 1, the labor of the user is not increased.

  Furthermore, in this embodiment, since the rating level is determined by a keyword set in advance by the user, there is little possibility that the rating level is different or wrong for each content.

  On the other hand, in this embodiment, even when a plurality of in-house servers are arranged, rating information can be added to the contents from the plurality of in-home servers in the transfer apparatus 1, so that the cost and The effort is not different from the case of a single home server.

  Further, in the present embodiment, it is possible to automatically update or add the rating information of all subordinate home servers by upgrading the firmware of the transfer apparatus 1 (centralized management is possible).

  Furthermore, in the present embodiment, even when the rating level is written in the content in the home server 2 by mistake, the correct rating level can be reset in the transfer device 1.
