[Description of Operation of First Embodiment]
Next, the operation of the present embodiment will be described in detail.

  First, the operation when registering use restriction information in the content storage terminal device 40 will be described.

  When registering use restriction information, the user displays a use restriction information registration screen on the display unit 34 of the use restriction granting terminal device 30, and inputs a content ID and use restriction information using this screen (FIG. 7). Step S71). In this embodiment, it is assumed that a user ID of a user who can use the content specified by the content ID is input as the use restriction information. Now, for example, it is assumed that “0001” is input as a content ID and user IDs “U1” and “U2” are input as usage restriction information.

  The restriction granting side control means 32 in the use restriction granting terminal device 30 sends a use restriction information registration request including the input content ID and use restriction information to the content storage terminal device 40 via the transmission / reception means 31 and the network NW1. Transmit (step S72).

  When the storage side control means 42 in the content storage terminal device 40 receives the use restriction information registration request via the network NW1 and the transmission / reception means 41, it registers the use restriction information in the corresponding entry of the use restriction information storage unit 45. (Step S73). In this example, as shown in FIG. 8, user IDs “U1” and “U2” are registered in the entry whose content ID is “0001”. In FIG. 8, the content for which usage restriction information is not registered indicates that all users can use the content.

  Next, an operation when registering the integrated usage authority information in the content storage terminal device 40 will be described.

  The collection means 23 in the use authority generation terminal device 20 transmits a use authority acquisition request using the short-range communication means 24 every predetermined time (step S91).

  When the portable side control means 12 of each of the portable terminal devices 10-1 to 10-n existing in the detection area 60 receives the use authority acquisition request via the short-range communication means 13, the use side information is stored in the use authority information storage unit 11. The authority information is read, and the read use authority information is transmitted using the short-range communication means 13 (step S92). In the present embodiment, the use authority information storage unit 11 in each of the mobile terminal devices 10-1 to 10-n has the user U1 who possesses the mobile terminal devices 10-1 to 10-n as the use authority information. It is assumed that user IDs “U1” to “Un” of .about.Un are registered.

  When the collection means 23 in the use authority generation terminal device 20 receives the user IDs “U1” to “Un” sent from the mobile terminal devices 10-1 to 10-n via the short-range communication means 24, These are passed to the integrated usage authority generation means 22, and the integrated usage authority generation means 22 generates integrated usage authority information indicating the usage authority for the contents of the entire users U 1 to Un based on the user ID passed from the collection means 23. (Step S93). In the present embodiment, the integrated usage authority generation unit 22 generates integrated usage authority information by enumerating the user IDs “U1” to “Un” of the users U1 to Un passed from the collection unit 23. For example, two mobile terminal devices 10-1 and 10-2 exist in the detection area 60, and two user IDs “U1” and “U2” passed from the collection unit 23 exist. In some cases, the integrated usage authority generation unit 22 generates “U1, U2” as the integrated usage authority information.

  Thereafter, the integrated use authority generation means 22 transmits an integrated use authority information registration request including the integrated use authority information generated in step S93 to the content storage terminal device 40 using the transmission / reception means 21 (step S94).

  When the storage-side control unit 42 in the content storage terminal device 40 receives the integrated usage authority information registration request via the transmission / reception unit 41, the storage side control unit 42 registers the integrated usage authority information included in the integrated usage authority information storage unit 46. (Step S95).

  The processes in steps S91 to S95 described above are performed every predetermined time, and the contents of the integrated usage authority information storage unit 46 are also updated every predetermined time.

  Next, an operation when the user uses content will be described.

  When using the content, the user performs a content menu display operation using the input unit 53 of the content display terminal device 50. Thereby, the display-side control means 52 in the content display terminal device 50 transmits a content menu display request to the content storage terminal device 40 via the transmission / reception means 51 (step S101 in FIG. 10).

  When the storage-side control means 42 in the content storage terminal device 40 receives the content menu display request via the transmission / reception means 41, the content-side control means 42 detects in consideration of the contents of the use restriction information storage unit 45 and the integrated use authority information storage unit 46. A content menu containing only the content that can be used by the users U1 to Un in the area 60 is generated and transmitted to the content display terminal device 50 (steps S102 and S103).

  Here, the content menu generation processing performed in step S102 will be described in detail with reference to the flowchart of FIG.

  The storage-side control means 42 pays attention to one of the contents stored in the content storage unit 44 (for example, the content with the content ID “0001”) (step S111). Thereafter, the storage-side control unit 42 stores the usage restriction information of the content of interest (usage restriction information associated with the content ID “0001” in the usage restriction information storage unit 45) and the integrated usage authority information storage unit 46. Based on the registered integrated use authority information, it is determined whether or not information for accessing the content of interest is put on the content menu (step S113).

  This determination is performed, for example, by checking whether there is a user ID that is not included in the use restriction information among the user IDs included in the integrated use authority information. That is, when there is a user ID that is not included in the usage restriction information among the user IDs included in the integrated usage authority information, a user who does not have the usage authority for the content of interest is detected in the detection area 60. It is determined that the content is not included in the content menu. On the other hand, when all the user IDs included in the integrated usage authority information are included in the usage restriction information, all users in the detection area 60 have the usage authority for the content of interest. Therefore, it is determined to be put on the menu. For example, when the use restriction information for the content of interest registered in the use restriction information storage unit 45 is “U1, U2,” the integrated use authority information registered in the integrated use authority information storage unit 46 is “U1, U2. ”,“ U1 ”, and“ U2 ”, it is determined to be put on the content menu, and in other cases, it is determined not to be put on the content menu.

  If it is determined not to be placed on the content menu (NO in step S113), attention is paid to the next content (step S111). On the other hand, if it is determined to be put on the content menu (step S113 is YES), information for accessing the content of interest is added to the menu, and then the process of step S111 is performed again. The accumulation-side control means 42 repeats the above processing until there is no unfocused content (until NO in step S112). The above is the details of the processing performed in step S102 of FIG.

  Returning to FIG. 10 again, the transmission / reception means 51 in the content display terminal device 50 displays the content menu sent from the content storage terminal device 40 on the display unit 54 (steps S103 and S104), and the user selects the content menu. When the content to be used (displayed) is selected, a content acquisition request for requesting acquisition of the selected content is transmitted to the content storage terminal device 40 (step S105).

  Thereby, the storage-side control means 42 in the content storage terminal device 40 retrieves the requested content from the content storage unit 44 and transmits it to the content display terminal device 50 (step S106), and displays the content in the content display terminal device 50. The side control means 52 displays the sent content on the display unit 54 (step S107).

  In the above description, the user ID of the user is used as the usage authority information. Instead, the age of the user or the usage authority level given to the user may be used. . When the user age is used as the usage authority information, for example, the minimum age of the user who can use the content may be used as the usage restriction information. When the usage authority level is used as the usage authority information, the minimum usage authority level of the user who can use the content may be used as the usage restriction information.

  Further, in step S93 of FIG. 9 described above, the integrated usage authority information is generated by enumerating the usage authority information collected from each of the mobile terminal devices 10-1 to 10-n existing in the detection area 60. However, when the usage authority level is used as the usage authority information, the usage authority level collected from each of the mobile terminal devices 10-1 to 10-n is the lowest level or the highest level. It may be integrated use authority information.

  In step S113 of FIG. 11 described above, if a user ID that is not included in the use restriction information is present in the user ID included in the integrated use authority information, the content of interest is displayed in the content menu. When it is determined that the user ID included in the integrated use authority information is all included in the use restriction information, it is determined that the user ID is included in the menu, but it is included in the integrated use authority information. If at least one user ID is included in the usage restriction information, it is determined to be put on the menu, and if no user ID is included in the usage restriction information, it is determined not to be put on the menu. Also good. That is, if there is even one user who has the right to use the content of interest in the detection area 60, it is determined that the user is placed on the content menu. If there is no user who has the right to use, the content menu You may make it determine with not putting on.

  In the above description, the usage authority generation terminal device 20 collects usage authority information of each user U1 to Un by transmitting a usage authority acquisition request to the mobile terminal devices 10-1 to 10-n every predetermined time. However, when the users U1 to Un enter the detection area 60, the use authority information may be transmitted to the use authority generation terminal apparatus 20 using the mobile terminal apparatuses 10-1 to 10-n. .

  In the above description, the use of the content is restricted depending on whether or not the information for accessing the content is put on the content menu. However, in steps S102 and S106 in FIG. In addition, the use of content may be restricted by performing the following processing. In step S102, a content menu including information for accessing all content is generated. In step S <b> 106, first, use restriction information for the content requested to be acquired by the content acquisition request is input from the use restriction information storage unit 45. Thereafter, based on the input usage restriction information and the integrated usage authority information registered in the integrated usage authority information storage unit 46, it is determined whether or not the content is to be acquired. This criterion is the same as the criterion for determining whether or not to put on the content menu. If it is determined to be acquired, the corresponding content stored in the content storage unit 44 is transmitted to the content display terminal device 50. If it is determined not to be acquired, a message indicating that there is no use authority. Is transmitted to the content display terminal device 50.

  In the above description, the use authority information storage unit 11 in which use authority information for the contents of the users U1 to Un is registered is provided in each of the mobile terminal apparatuses 10-1 to 10-n. The use authority information of each of the users U1 to Un is collected by communicating with the mobile terminal devices 10-1 to 10-n, but may be as follows. The usage authority information ID for identifying the usage authority information of the users U1 to Un is registered in each mobile terminal apparatus 10-1 to 10-n, and the usage authority information of each user U1 to Un is registered in the server. Keep it. The usage authority generation terminal device 20 communicates with the mobile terminal devices 10-1 to 10-n, acquires the usage authority information IDs of the users U1 to Un, and uses the acquired usage authority information IDs as servers.
