Abstract

PROBLEM TO BE SOLVED: To lighten a burden on a user of a new information processing apparatus when registering the new information processing apparatus in a server by canceling registration of another information processing apparatus.SOLUTION: When an upper-limit number of two information processing apparatuses (information processing apparatuses 100A, 100B) which use contents is registered in a server 800 and an information processing apparatus 100C is further registered in the server 800 in this state, a user makes the server 800 change the registration state of the information processing apparatuses 100A, 100B temporarily to a content-unusable state. Consequently, even when the user cannot uniquely specify an information processing apparatus whose registration is to be canceled, the information processing apparatus 100C can be registered in the server 800. Then service (content) that the server 800 provides can be used through the information processing apparatus 100C.

Description

  The present invention relates to an information processing apparatus and an information processing system, and more particularly to an information processing apparatus that uses content based on registration in a server and an information processing system including such an information processing apparatus.

  Conventionally, in a system in which a server provides a service such as content distribution to a client terminal, the service may be provided only to the client terminal registered in the server. In this case, generally, the number of client terminals that can be registered in the server is limited for each user. For example, when the above limit is exceeded by installing an application program (an example of a service) in a client terminal newly purchased by a certain user, the user installs the application program in the new client terminal. Needs to deregister any of the client terminals.

  In a client terminal that has been deregistered, generally, at least a part of services provided by the server cannot be used. For example, virus check software cannot be upgraded, and electronic book readers cannot purchase new books. As a result, inconvenience may occur in the client terminal whose registration has been canceled. Therefore, it is necessary to carefully select which client terminal is to be deregistered. In a system designed such that once a client terminal has been unregistered, it cannot be registered again, the client terminal must be selected with particular care.

<Outline of processing>
In the information processing system according to the present embodiment, when a user intends to use content stored in the server 800 in the information processing apparatus 100, the user registers the account of the information processing apparatus 100 in the user management information 86 of the server 800. Further, as described with reference to FIG. 4, the “registered state” of the information processing apparatus 100 needs to be “registered”. As described above, in the present embodiment, the upper limit of the number of information processing apparatuses 100 that the server 800 can simultaneously register with “registered” for one account name is limited to “2”. .

  Here, referring to FIG. 5 and FIG. 6, in the information processing system, a user who owns three information processing apparatuses 100A, 100B, and 100C is registered with “registered” in two of the three. In this state, the contents of the processing when the third vehicle registration is desired will be described. 5 and 6 are diagrams schematically showing information exchange between apparatuses in the information processing system. In these figures, the order of information exchange is indicated by numbers such as “(1)”, “(2)”, and the like.

  Referring to FIG. 5, the user first instructs information processing apparatus 100 </ b> A to register account information in server 800 as indicated by (1). As a result, the registration processing unit 51 of the information processing apparatus 100A sends the account name (user_A), terminal ID (0123456789), and terminal name (myphone) of the information processing apparatus 100A to the server 800 together with the registration request. Send.

  It is assumed that the registration request for the information processing apparatus 100A is the first registration request with the user account name.

Accordingly, the registration processing unit 51 of the information processing apparatus 100B sends the account name (user_A), the terminal ID (0123012301), and the terminal name (mytablet) of the information processing apparatus 100B to the server 800 together with the registration request. Send.

  Even if the account information of the information processing apparatus 100A is registered as described above, the number of account information registered together with the registration state “registered” in the user management information 86 is “1”, which is the upper limit. It has not reached “2”. In other words, the registration management unit 88 can register the information processing apparatus 100B with “registered” at this point. Then, the registration management unit 88 registers the information received from the information processing apparatus 100B in the storage unit 83 as the user management information 86 together with the registration state “registered”, as indicated by (4).

  By the processes (1) to (4) described above, the account information of the information processing apparatus 100A and the information processing apparatus 100B is registered in the storage unit 83 as the user management information 86 together with the information “registered”. . FIG. 5 shows the user management information 86 in this state.

  Next, as shown in (5), the user instructs the information processing apparatus 100C to register the account information in the server 800. Thus, the registration processing unit 51 of the information processing apparatus 100C sends the account name (user_A), the terminal ID (9876543210), and the terminal name (mynewphone) of the information processing apparatus 100C to the server 800 together with the registration request. Send.

  In the user management information 86 of the storage unit 83, two terminal IDs are already registered in association with the account name (user_A) by the above (2) and (4). For this reason, the registration management unit 88 cannot register the account information of the information processing apparatus 100C as the user management information 86 in this state. Accordingly, the registration management unit 88 determines that the registration of the information processing apparatus 100C has failed as indicated by (6), and performs registration of the information processing apparatus 100C as indicated by (7). Notify failure. The notification may include, for example, information for specifying another information processing apparatus that is already registered in the user management information 86.

  Upon receiving the notification of the failure, for example, information as shown in a frame 41 in FIG. 5 is displayed on the display unit 40 of the information processing apparatus 100C. More specifically, the information processing apparatus 100 (information processing apparatuses 100A and 100B) having the same account name as that of the information processing apparatus 100C already registered in the user management information 86 is displayed on the display unit 40 of the information processing apparatus 100C. The information that identifies is displayed.

  FIG. 5 shows, as (8X), a process constituting a comparative example for the present embodiment as a process of the information processing apparatus 100C in response to the notification. The process indicated as (8X) is a process of designating an information processing apparatus that is already registered in the user management information 86 and whose registration is to be canceled in the information processing apparatus 100C. Information assumed to be displayed on the display unit 40 of the information processing apparatus 100 </ b> C in the processing is shown in a frame 42.

  In (8X), the user can select the information processing apparatus 100 to be deregistered from among the other information processing apparatuses 100 owned by the user. For this reason, (8X) is also considered to be an easy process for the user. However, for example, when the user cannot accurately identify the information processing apparatus 100 from the terminal name, that is, when the user cannot remember whether the terminal name “myphone” refers to the information processing apparatus 100A or the information processing apparatus 100B, This process is not easy for the user.

  In the present embodiment, the user does not select the information processing device to be deregistered, but instructs the server 800 to change the registered content of another information processing device so that the service cannot be used. More specifically, the user changes to the information processing apparatus 100C the content of registration of the other information processing apparatus 100 with respect to the server 800 so that the other information processing apparatus 100 cannot use it. Let me tell you.

  Such processing by the information processing apparatus 100C is indicated as (8) in FIG. In (8), the registration processing unit 51 of the information processing apparatus 100C uses the account information of the two other information processing apparatuses 100 (information processing apparatuses 100A and 100B) received from the server 800 in (7) of FIG. Then, a request (instruction) is transmitted to the server 800 for changing the registered contents of the account information so that the service (content use) cannot be used.

  In response to this, the registration management unit 88 of the server 800 changes the registration status of the information processing apparatuses 100A and 100B in the user management information 86 from “registered” to “disabled” as shown in (9). To do. Then, the registration management unit 88 notifies the information processing apparatus 100C of the completion of the change.

  Then, the registration management unit 88 requests the server 800 to register the account information of the information processing apparatus 100C again as indicated by (10).

  As a result of the process indicated by (9), in the user management information 86, the terminal ID registered with the registration state “registered” is lost among the terminal IDs associated with the account name “user_A”. Therefore, in response to the request of (10), the registration management unit 88 registers the account information of the information processing apparatus 100C in the user management information 86 together with the registration state “registered” as indicated by (11). . FIG. 6 shows the contents of the user management information 86 at this time.

  Thereafter, according to the information received from the information processing apparatuses 100A and 100B that have changed the registration state in the user management information 86 in the process (9), the registration management unit 88 changes the registration contents in the user management information 86. change.

  For example, when a registration request for use of a service is received from the information processing apparatus 100A as shown in (12), the registration management unit 88 sends the information processing apparatus 100A to the information processing apparatus 100A as shown in (13). It is notified that the registration state of the information processing apparatus 100A has been changed to “disabled”. In FIG. 6, the notification is described as “provisional release state notification”. The user selects whether to accept the cancellation of registration of the information processing apparatus 100A. When accepting the cancellation of the registration of the information processing apparatus 100A, the user causes the information processing apparatus 100A to notify the server 800 of “registration cancellation acceptance”, as indicated by (14). In response to this, the registration management unit 88 deletes the account information of the information processing apparatus 100 </ b> A from the user management information 86.

  In addition, the user may select to refuse to cancel the registration of the information processing apparatus 100B. In this case, the user causes the information processing apparatus 100B to transmit information for rejecting the registration cancellation to the server 800. More specifically, as indicated by (15), the registration processing unit 51 of the information processing apparatus 100B requests the server 800 for registration for using the service, and accordingly, indicated by (16). As described above, the registration management unit 88 of the server 800 notifies the information processing apparatus 100B that the registration state of the information processing apparatus 100B has been changed to “disabled”. On the other hand, the registration processing unit 51 of the information processing apparatus 100B transmits a refusal to cancel the registration of the account information (data indicating) as indicated by (17). Upon receiving the rejection from the information processing apparatus 100B, the registration management unit 88 of the server 800 returns the registration state in the account information of the information processing apparatus 100B in the user management information 86 to “registered”.

  In addition, if registration cancellation is received from the information processing apparatus 100B before receiving the registration cancellation acceptance from the information processing apparatus 100A, the registration management unit 88 returns the registration state of the information processing apparatus 100B to “registered”. Then, the account information of the information processing apparatus 100A is deleted from the user management information 86. In the user management information 86, the account information of the information processing apparatus 100C is registered together with the registration state “registered” in (11), and the registration state of the information processing apparatus 100B is returned to “registered” in (17). Thus, the number of information processing apparatuses 100 in which the account information is registered together with the registration state “registered” is “2”. In this case, the account information of the information processing apparatus 100A cannot be registered together with “registered”. Therefore, the account information of the information processing apparatus 100A is deleted from the user management information 86.

  The information processing system according to the present embodiment is designed so that once it is registered as “registered”, the account information of the information processing apparatus 100 that can no longer use the service is never registered in the “registered” state. There is also a possibility. In this case, the account information once registered by “registered” is changed to “unregistered” instead of being deleted from the user management information 86. “Unregistered” indicates that the content cannot be used in the future.

<Processing sequence>
FIG. 7 shows processing when the information processing apparatus 100A and the information processing apparatus 100B are registered in the server 800 as a terminal (information processing apparatus) that can use the content, and the content can be used in the information processing apparatus 100C. FIG. In this sequence diagram, the following two points 1) and 2) are assumed.

1) The upper limit of the number of terminals that can be used by the same user (account name) is limited to two.
2) First, the information processing apparatuses 100A and 100B of the same user register with the server 800 as usable terminals. Then, the user desires to register the newly purchased information processing apparatus 100C in the server 800 as a usable terminal. The user desires to cancel the registration of the information processing apparatus 100A instead of the information processing apparatus 100C. However, when the sequence of FIG. 7 is executed, the user has only the information processing apparatus 100C and does not have the information processing apparatuses 100A and 100B. And the said user cannot distinguish information processing apparatus 100A and information processing apparatus 100B only with a terminal name. However, the user can understand whether the terminal name corresponds to the information processing apparatus 100A or the information processing apparatus 100B by looking at the main body of the information processing apparatus 100A and / or the information processing apparatus 100B.

  Now, referring to FIG. 7, the user uses information processing apparatus 100A to authenticate server 800, and then registers information processing apparatus 100A as a terminal that uses content (step S10). . For registration, the registration processing unit 51 of the information processing apparatus 100A transmits the account name (user_A) and the terminal ID (0123456789) of the information processing apparatus 100A to the server 800.

  At this time, there is no terminal registered in the user management information 86 in association with the account name user_A. Therefore, the registration management unit 88 of the server 800 uses the account name (user_A) and the terminal ID (0123456789) received from the information processing apparatus 100A in the user management information 86 as the registration status “use” for the information processing apparatus 100A. The information is registered together with “registered”, and the information processing apparatus 100A is notified of the successful completion of registration (step S40).

  In step S10, the registration processing unit 51 of the information processing apparatus 100A can further transmit the terminal name of the information processing apparatus 100A to the server 800. In step S40, the registration management unit 88 of the server 800 can also register the terminal name in the user management information 86 in association with the account name of the information processing apparatus 100A. That is, the registration management unit 88 of the server 800 can register not only the account name and terminal ID of the information processing apparatus 100 but also the terminal name as described with reference to FIG.

  Next, after authenticating the server 800 using the information processing apparatus 100B, the user registers the information processing apparatus 100B as a terminal that uses content (step S20). For registration, the registration processing unit 51 of the information processing apparatus 100B transmits the account name (user_A) and the terminal ID (0123012301) of the information processing apparatus 100B to the server 800.

  At this time, in the user management information 86, the information processing apparatus 100A is the only terminal registered in association with the account name user_A. That is, the number of registered information processing devices is smaller than the upper limit “2”. Therefore, the registration management unit 88 of the server 800 registers the account name (user_A) and the terminal ID (0123012301) in the user management information 86 together with the registration status “available” (registered) for the information processing apparatus 100B. Then, the information processing apparatus 100B is notified that the registration has been completed normally (step S41).

  Next, after authenticating the server 800 using the information processing apparatus 100C, the user requests registration of the information processing apparatus 100C as a terminal that uses the content (step S30). In order to request registration, the registration processing unit 51 of the information processing apparatus 100C transmits the account name (user_A) and the terminal ID (9876543210) of the information processing apparatus 100C to the server 800.

  At this time, in the user management information 86, the information processing apparatus 100A and the information processing apparatus 100B are already registered in association with user_A. That is, in the user management information 86, the number of information processing apparatuses 100 registered together with the registration state “registered” has already reached the upper limit number (two). Therefore, the registration management unit 88 notifies the information processing apparatus 100C of an error (Step S42). The notification of the error includes notification of the terminal IDs (0123456789, 0123012301) of the information processing apparatuses 100A and 100B that are already registered in the user management information 86. In the registration management unit 88 of the present embodiment, an account name is additionally registered for the information processing apparatus. Therefore, in the present embodiment, the error notification includes notification of the terminal names (myphone, mytablet) of the information processing apparatuses 100A and 100B that are already registered in the user management information 86.

  In response to this notification, the information processing apparatus 100C displays, on the display unit 40, a screen for inquiring to cancel the registration of the information processing apparatuses 100A and 100B using the notified information of the information processing apparatuses 100A and 100B. The screen displayed here is, for example, shown as a frame 42 in FIG. In the present embodiment, the user of the information processing apparatus 100C does not need to select the information processing apparatus 100 to be deregistered. That is, using the information processing apparatus 100 </ b> C, the user temporarily gives permission to provide all services of the information processing apparatus 100 registered with “registered” in the user management information 86 to the server 800. Can be instructed to cancel. In response to the instruction, the registration processing unit 51 of the information processing apparatus 100C transmits the instruction to the server 800 (step S32).

  In response to the instruction, the registration management unit 88 of the server 800 changes the user management information 86 so that the account information of the information processing apparatuses 100A and 100B is temporarily disabled, and the change is normal. Is notified to the information processing apparatus 100C (step S43).

  Next, using the information processing apparatus 100C, the user registers the information processing apparatus 100C as a terminal that uses the content again (step S34). In step S34, the registration processing unit 51 of the information processing apparatus 100C transmits the account name, the terminal ID of the information processing apparatus 100C, and the like to the server 800.

  In response to this, the registration management unit 88 of the server 800 registers the terminal name and the like of the information processing apparatus 100C together with the registration state “registered” as the user management information 86 in the storage unit 83, and if the registration is successful, that effect Is notified to the information processing apparatus 100C (step S44).

  Next, when the user uses the information processing apparatus 100A, the information processing apparatus 100A accesses the server 800 in order to use the function (service) provided by the server 800 (step S12). The parameters of the information login transmitted when accessing the server 800 include, for example, an account name, a login password, and a terminal ID.

  In response to the access, the server 800 notifies the information processing apparatus 100A of information according to the registration state of the information processing apparatus 100A (step S45). More specifically, the registration state of the information processing apparatus 100A (terminal ID: 0123456789) of the user (user_A) is temporarily deregistered on the user management information 86 as a result of the update in step S43. State (disabled). For this reason, in step S45, the registration management unit 88 notifies the information processing apparatus 100A that the registration state of the information processing apparatus 100A is disabled.

  When the user receives the notification in step S45 and agrees to cancel the registration of the information processing apparatus 100A, the information processing apparatus 100A transmits a reply to that effect to the server 800 (step S14). More specifically, the information processing apparatus 100A displays a screen for selecting whether to cancel the registration of the information processing apparatus 100A or to continue using the information processing apparatus 100A upon receiving the notification in step S45. To do. When the user selects to cancel the registration of the information processing apparatus 100A, the registration processing unit 51 of the information processing apparatus 100A notifies the server 800 that the registration cancellation for the information processing apparatus 100A is accepted in step S14. To do.

  In response to the notification in step S14, the registration management unit 88 of the server 800 deletes the registration of the information processing apparatus 100A from the user management information 86 and notifies the information processing apparatus 100A to that effect (step S46). Instead of deleting the registration of the information processing apparatus 100A, information (for example, “unregistered”) indicating a state where the service cannot be used again may be registered as the registration state of the information processing apparatus 100A.

  In the user management information 86, even if the account information of the information processing apparatus 100B is returned to “registered” because the account information of the information processing apparatus 100A is deleted (or changed to “unregistered”), the registration state “ The number of information processing apparatuses 100 to which “registered” is attached falls within the upper limit “2”. Therefore, in response to the deletion of the account information of the information processing apparatus 100A (or change to “unregistered”), the registration management unit 88 sets the registration state of the account information of the information processing apparatus 100B to “registered” in step S47. Return to. Next, when the user uses the information processing apparatus 100B, the information processing apparatus 100B accesses the server 800 in order to use the function (service) provided by the server 800 (step S22).

  In response to the access of the information processing apparatus 100B, the server 800 notifies that the registration state of the account information of the information processing apparatus 100B has been returned to “registered” (step S47). When the registration processing unit 51 of the information processing apparatus 100B normally receives the notification, the registration processing unit 51 replies to that effect.

  As described above, with the sequence described with reference to FIGS. 5 to 7, in the state where the two information processing apparatuses (information processing apparatuses 100 </ b> A and 100 </ b> B) that are the upper limit for content use are registered in the server 800, Further, when registering the information processing apparatus 100C with the server 800, the user causes the server 800 to temporarily change the registration state of the information processing apparatuses 100A and 100B to a state where the content cannot be used. Thus, even when the user cannot uniquely identify the information processing device to be deregistered, the user can register the information processing device 100C with the server 800, and the service provided by the server 800 in the information processing device 100C. (Content) can be used.

  Thereafter, the user can delete the account information of the information processing apparatus 100A from the user management information 86 by operating the information processing apparatus 100A. That is, the user can operate the device itself for deleting registration to instruct deletion of the account information of the device. Note that information indicating that registration deletion is not accepted is transmitted from one device (information processing device 100B) among the devices temporarily unavailable for content as described above to the server 800. Thus, the registration of the remaining device (information processing device 100A) can be deleted ((17) in FIG. 6).

  Note that instead of deleting the account information, the registration state of the account information may be changed to a state where the content cannot be used again.

<Server processing>
With reference to FIG. 8, the content of the process which the server 800 performs in the information processing system of this Embodiment is demonstrated. FIG. 8 is a flowchart of processing executed by the registration management unit 88 of the server 800. In this example, instead of deleting the account information registered with “registered”, a case where the registration state of the account information is changed to a state where the content can no longer be used is shown.

  When a request is received from any of the information processing devices 100A to 100C, the registration management unit 88 advances control according to the type of the request in step S80.

  If the received request is a request for deregistration of account information of the information processing device in the user management information 86, the registration management unit 88 advances the control to step S82. The request is indicated by (14) in FIG. 6, and is indicated by “registration cancellation request” in FIG.

  If the received request is a request for registration of account information of the information processing apparatus in the user management information 86, the registration management unit 88 advances the control to step S84. The request is indicated by (1) or (3) in FIG. 5, indicated by (10) in FIG. 6, and indicated by “registration request” in FIG. 6 also corresponds to a request for registration of the information processing apparatus 100B from the information processing apparatus 100B to the server 800. Therefore, registration of account information of the information processing apparatus is also performed. Included in the request.

  If the received request is a request to temporarily cancel the registration of the account information of the information processing apparatus in the user management information 86, the registration management unit 88 advances the control to step S90. This request is indicated by (8) in FIG. 6, and is indicated by “temporary registration cancellation request” in FIG.

  In step S <b> 82, the registration management unit 88 changes the registration state of the corresponding terminal ID in the user management information 86 to “unregistered” and ends the process. At this time, the registration management unit 88 notifies the information processing apparatus corresponding to the corresponding terminal ID that the change has been completed normally. The registration management unit 88 may delete the registration of the corresponding terminal ID information from the user management information 86 instead of changing the registration state to “unregistered”.

  In step S84, the registration management unit 88 is an information processing apparatus registered with the same account name as that of the information requesting information processing apparatus in the user management information 86, and the registration status is registered as “registered”. It is determined whether or not the number of information processing apparatuses that are present is equal to or greater than an upper limit that can provide a service for the same account name. If the registration management unit 88 determines that the number is equal to or greater than the upper limit value, the registration management unit 88 proceeds to step S88. If the number is determined to be less than the upper limit value, the registration management unit 88 proceeds to step S86.

  In step S86, the registration management unit 88 registers the account information of the information processing apparatus that requested the registration request together with the registration state “registered”, and ends the process. At this time, the registration management unit 88 notifies the requesting information processing apparatus that the registration has been completed normally.

  In step S88, the registration management unit 88 is an information processing apparatus registered with the registration status “registered” in the user management information 86, and is registered with the same account name as the request source of the registration request. Is transmitted to the information processing apparatus that requested the registration request, and the process is terminated. At this time, the registration management unit 88 notifies an error to the information processing apparatus that requested the registration request.

  In step S90, the registration management unit 88 is an information processing apparatus registered with the registration status “registered” in the user management information 86 and has the same account name as that of the information processing apparatus that requested the temporary deregistration request. About a processing apparatus, a registration state is changed into "disabled" and a process is complete | finished. At this time, the registration management unit 88 notifies the information processing apparatus requesting the temporary registration cancellation request that the temporary registration cancellation has been normally completed.

  In the present embodiment described above, when the information processing apparatus 100C requests the server 800 to register account information, the information is associated with the same account information as the account information of the information processing apparatus 100C in the user management information 86. If the request is rejected based on the fact that other information processing apparatuses (information processing apparatuses 100A and 100B) are registered, a temporary registration cancellation request is transmitted to the server 800. The temporary registration release request temporarily registers the device-specific information of the other information processing devices (information processing devices 100A and 100B) so that the other information processing devices (information processing devices 100A and 100B) cannot use the content. It is an example of the instruction | indication to cancel | release.

  In response to the temporary registration cancellation request, the server 800 changes the registration status of the other information processing apparatus to “disabled”. As a result, the other information processing apparatus is temporarily unable to use the service (content) provided by the server 800.

  On the other hand, when the information processing apparatus 100C receives a notification from the server 800 that the registration cancellation corresponding to the temporary registration cancellation request is completed, the information processing apparatus 100C requests the server 800 to register the account information of the information processing apparatus 100C again. In response to the request, the server 800 registers the account information of the information processing apparatus 100C in the user management information 86. Accordingly, a user who uses the information processing apparatus 100C can use a service (content) provided by the server 800 in the information processing apparatus 100C without selecting the information processing apparatus 100 to be canceled.

  Thereafter, the information processing apparatus 100 whose registration state has been changed to “disabled” in response to the temporary registration cancellation request accesses the server 800 to receive a notification of the change from the server 800. The information processing apparatus that has received the notification transmits information (cancellation acceptance information) that informs the server 800 of acceptance of the cancellation of registration of the information processing apparatus, by a user operation or the like. The server 800 deletes the registration in the user management information 86 or changes the registration state to “unregistered” for the information processing apparatus that has transmitted the release acceptance information. The registered state “unregistered” means a state in which the service provided by the server 800 cannot be used. At this time, the server 800 may change the registration status of the remaining information processing apparatuses whose registration status has been changed to “disabled” to “registered”.

  The information processing apparatus that has received the notification can also transmit information (cancellation rejection information) for notifying that registration cancellation is not accepted by a user operation or the like. The server 800 changes the registration status to “registered” for the information processing device that has transmitted the cancellation rejection information, and changes the registration status for the remaining information processing devices to “unregistered” among the other information processing devices ( Or delete registration).

  The server 800 may inquire of the information processing apparatus whose registration state has been changed to “disabled” in response to the temporary registration cancellation request whether to accept the cancellation of registration in the user management information 86. In this case, the server 800 deletes the registration in the user management information 86 or changes the registration state to “unregistered” for the information processing apparatus that has replied if accepted. Also, the server 800 changes the registration status to “registered” for the information processing device that has returned that it does not accept, and changes the registration status for the remaining information processing devices among the other information processing devices to “unregistered”. (Or delete the registration).

  In the present embodiment described above, the upper limit of the number of terminals that can be permitted to use the service (content) simultaneously for one account name is “2”. For this reason, when the account information of two terminals is registered as “disabled”, when the status of the account information of one terminal is returned to “registered”, the account information of the other terminal is deleted, or Changed to "unregistered". Also, in the above case, if registration cancellation is accepted for the account information of one terminal, the account information of the terminal is deleted or “unregistered”, and the status of the account information of the other terminal is returned to “registered” .

  When the upper limit of the number of terminals that can use the service (content) for one account name at the same time is “3” or more, and the status of three or more terminals is simultaneously “disabled”, Several methods of processing are conceivable. For example, the server 800 sequentially receives registration requests from three or more terminals registered with “disabled”. Then, the server 800 changes the status of the account information to “registered” in order from the terminal that received the registration request. Then, when the number of terminals registered by “registered” reaches the upper limit, the account information of the terminals whose state remains “disabled” is deleted or “unregistered”. Alternatively, when the server 800 receives a notification from one of the three or more terminals registered with “disabled” that the registration cancellation is accepted, the server 800 deletes the account information of the terminal that transmitted the notification. Or, the status of the account information is changed to “unregistered”, and the status of the account information of all other terminals is changed to “registered”.

  Further, in the present embodiment described above, the information processing apparatus (information processing apparatus 100C) that has been denied registration of account information instructs the temporary cancellation of registration of other account information, and then from the server 800. A request for registration of account information was sent again after waiting for notification of cancellation of registration of other account information. The request for registering the account information again may be transmitted to the server 800 without waiting for the cancellation notification.

  When a request for re-registering account information is transmitted without waiting for the cancellation notification, the information processing apparatus 100C may transmit the request together with an instruction for temporarily canceling registration of other account information. It may be transmitted at a timing different from the instruction (for example, after the instruction).

  More specifically, in the processing described with reference to FIG. 7, the information processing apparatus 100 </ b> C transmits a request for temporarily canceling registration of other account information to the server 800 in step S <b> 32, After receiving the reply from 800 (step S43), the registration request is transmitted again in step S34. In this regard, the information processing apparatus 100C may transmit the registration request in step S34 to the server 800 without waiting for a reply from the server 800 (step S43).

  In the information processing system described above, the number of account information permitted to be registered for each account name is “2”, but the present disclosure is a system in which the number of permitted account information is “3” or more. It can also be applied to. In such a system, among the information processing devices corresponding to the account name, the upper limit number of account information permitted to be registered has already been registered in the server 800, and one new information processing device is not available. Assume that a request for temporarily canceling registration of account information of the information processing apparatus ((8) in FIG. 6) is transmitted to the server 800. In this case, the server 800 may change all the registration states of the already registered account information to “disabled”, and a minimum number of accounts for registering account information of a new information processing apparatus. The registration state of information may be set to “disabled”. That is, when the upper limit number is “3” and the account information of three units has already been registered and a request for temporary release is received from a new information processing apparatus, the server 800 All account information may be set to “disabled”, or the minimum number for registering account information of a new information processing apparatus, that is, account information for two of the three sets to “disabled” good.

  Which information processing device's account information is set to “disabled” is specified by, for example, the information processing device that newly requested registration. More specifically, the server 800 notifies the information processing apparatus that has newly requested registration of account information of information (for example, a terminal name) that identifies the information processing apparatus that has already registered the account information. To do. As a result, the information processing apparatus that has received the notification displays information that identifies the information processing apparatus that has already been registered, as indicated by a frame 42 in FIG. The user of the information processing apparatus that has received the notification designates at least two information processing apparatuses whose registration is temporarily canceled from the displayed information processing apparatuses. The information processing apparatus that has received the notification notifies the server 800 of the specified information processing apparatus. The server 800 changes the registration state of the account information to “disabled” for the notified information processing apparatus (information processing apparatus specified by the user). As a result, a user who intends to newly register account information of an information processing apparatus does not determine account information (or account information to be deregistered) from which the service can no longer be used, but temporarily determines the account information. You can specify the account information to cancel the registration of information. Further, the user need not narrow down the information processing device (account information) to be specified to one.
