Exists.

  It is considered that it is not preferable from the viewpoint of education and security to allow children and the like to freely use devices having various functions as described above. For this reason, it is desirable to place some restrictions on functions when used by children and the like.

  Therefore, in a high-performance home game machine, for example, various ratings are set in game software, and a rating level permitting use can be set in the setting of the main body. In addition, regarding the playback of commercially available video content, there are models that can control the permission and non-permission of playback according to the rating set for the video content, and the models that can prohibit access to the Internet. Patent Document 1 and Patent Document 2 describe a technology related to access control according to rating.

  On the other hand, remote desktop technology, which is a kind of distributed system technology for cooperating a plurality of information devices connected to a network, is spreading. According to this remote desktop technology, screen information of an application running on the server device is transmitted from the server device to the client device, and the client device can generate and display a user interface screen based on the received information. .

  Further, the client device creates a response screen according to the screen information according to the user operation input and updates the screen display, and transmits a user operation event according to the user operation input to the server device. On the server device side, the received user operation event is interpreted and processed by an application on the server device. Patent Document 3 describes remote desktop technology.

  In addition, products that apply such remote desktop technology and have introduced a remote desktop client function to home game machines have also appeared. As an example of such a home game machine, there is XBOX360 (registered trademark) of Microsoft Corporation.

After the connection with the personal computer, the consumer game machine as a client device can operate as a user interface device of a server application executed on the personal computer.

  That is, the operation information of the remote control and controller of the home game machine is sent to the personal computer via the network and passed to the server application on the personal computer. The screen information generated by the server application on the personal computer is transmitted to the consumer game machine via the network. The home game machine generates a display screen based on the received screen information and displays it on the television receiver.

  Thereby, in a consumer game machine, for example, an application to be activated can be selected from a server menu, and an application corresponding to the remote desktop function can be activated on a personal computer that is a server device. Then, the operation screen is displayed on the television receiver, and the server application running on the personal computer can be controlled by the remote controller or controller of the consumer game machine. As described above, the home game machine in which the remote desktop technology is introduced can be used as a remote operation terminal of the server device.

  In the building 10, an indoor LAN 20 is installed in the rooms 11-14. In the rooms 11, 12, and 13, the client terminals 30, 31, and 32 and the television receivers 40, 41, and 42 according to the first embodiment are installed, respectively. The television receivers 40, 41, and 42 are connected to client terminals 30, 31, and 32, respectively, and the client terminals 30, 31, and 32 are connected to the indoor LAN 20, respectively.

  In addition, server devices 50, 51, and 52, which are computers having a server function according to the first embodiment, are installed in the rooms 11, 12, and 14, respectively. Server devices 50, 51, and 52 are each connected to indoor LAN 20. The indoor LAN 20 is connected to an external network 61 via a gateway 60. The external network 61 is the Internet, for example.

  FIG. 2 shows an exemplary configuration of the client terminal 30 according to the first embodiment of the present invention. The client terminals 30, 31 and 32 described above can have the same configuration. In the following description, the client terminal 30 will be described as a representative unless otherwise specified. The control unit 110 includes, for example, a CPU, a ROM, and a RAM. The control unit 110 operates using the RAM as a work memory according to a program stored in the ROM, and controls the entire client terminal 30.

  The program is not limited to being stored in the ROM in advance, but may be acquired from the network 61 by the communication interface 105 described later, or may be acquired by reading from a recording medium such as a DVD or CD-ROM with a drive unit (not shown). Also good. The program acquired in this way is stored in, for example, a hard disk (not shown), and is read out by the CPU as necessary.

  The control unit 110 further includes three sub-blocks: a main control unit 100, a function providing unit 101, and an RDP client function unit 102. These sub blocks may be configured by operating a program on the CPU of the control unit 110, or may be configured by hardware. The main control unit 100 includes, for example, the above-described CPU, ROM, and RAM, and controls the function providing unit 101 and the RDP client function unit 102.

  The function providing unit 101 as a function providing unit provides various individual functions that are application functions when the client terminal 30 operates without being connected to the server devices 50, 51, and 52. In the example of FIG. 2, the function providing unit 101 provides a simple browser function, a network TV function, and a moving image playback function as individual functions. The individual functions are not limited to these, and may include other functions such as a music playback function and a game function. These individual functions are displayed on the basis of information acquired by communicating with the network 61 using the communication interface 105 described later, for example.

  The RDP client function unit 102 has functions as function restriction information transmission means, request means, and reception means. The RDP client function unit 102 connects the client terminal 30 to a server device, and provides a remote desktop protocol (hereinafter abbreviated as RDP) when the client terminal 30 is used as a remote user interface of the server.

  RDP is a higher-level protocol of TCP / IP. When a client terminal connects to a server apparatus and performs processing using a terminal service such as Windows 2000 (registered trademark) or a successor OS, the RDP is connected between the client terminal and the server apparatus. Used for communication. The RDP is mainly used for transmitting user input to the client terminal to the server apparatus and for the server apparatus to transmit screen information to the client terminal.

  A display interface (I / F) 103, an operation interface 104, a communication interface 105, and a USB interface 109 are connected to the control unit 110.

  The display interface 103 is an interface for causing the television receiver to output the screen image generated by the control unit 110. For example, the control unit 110 generates a screen image according to a command or the like, and outputs a display control signal for displaying the screen image. This display control signal is supplied to the display interface 103, converted into a display signal for display on an actual display device such as a television receiver, and output.

  An operation interface 104 serving as an operation receiving unit is an interface for receiving a user operation. The operation interface 104 receives, for example, an infrared signal transmitted in response to a user operation from the remote controller 130, converts it into a command for the main control unit 100, and outputs it. That is, the remote controller 130 modulates and transmits a control signal corresponding to a user operation into an infrared signal. The operation interface 104 receives and demodulates the infrared signal, and extracts a control signal. This control signal is transferred from the operation interface 104 to the main control unit 100. However, the operation interface 104 may receive a command transmitted in response to a user operation from a controller connected by wire.

  The communication interface 105 is an interface to the indoor LAN 20 and controls communication with the server devices 50, 51, and 52 connected to the indoor LAN 20, and the gateway 61 and the network 61 through the gateway 60.

The interface with the external device is not limited to USB, and an interface based on, for example, IEEE 1394 may be provided.

  A server information storage unit 120 and a function-specific setting table 106 are further connected to the control unit 110. The server information storage unit 120 and the function-specific setting table 106 are actually predetermined areas of a hard disk or non-volatile memory (not shown) provided in the client terminal 30. The server information storage unit 120 stores information related to the server device when the client terminal 30 is connected to the server devices 50, 51, and 52 and used. The server information storage unit 120 stores connection destination setting information 107 for storing information of the server devices 50, 51 and 52 to be connected, and RDP authentication information 108 for the server devices 50, 51 and 52.

  The function-specific setting table 106 serving as a function restriction information storage unit stores setting information for each individual function provided by the function providing unit 101 described above. A specific example of the setting information stored in the function-specific setting table 106 will be described later.

  FIG. 3 shows an exemplary configuration of the server device 50 according to the first embodiment of the present invention. The server devices 50, 51, and 52 described above can have the same configuration. Hereinafter, the server device 50 will be described as a representative unless otherwise specified. The RDP server unit 200 provides server functions to the client terminals 30, 31 and 32.

  A communication interface 201 and an RDP authentication information storage unit 202 are connected to the RDP server unit 200 as a function restriction information receiving unit, a request receiving unit, and an output transmitting unit. The communication interface 201 is an interface for the indoor LAN 20, and controls communication with the client terminals 30, 31 and 32 connected to the indoor LAN 20, and the network 61 made via the gateway 60 and the gateway 60. The RDP authentication information storage unit 202 stores authentication information for authenticating a client terminal having a connection request by RDP.

  Application registration unit 203 as an application registration unit registers applications # 1, # 2,..., #N which are application software activated by menu operations from client terminals 30, 31, and 32. Hereinafter, application software registered in the application registration unit 203 is referred to as a server application. The outputs of the applications # 1, # 2,..., #N registered in the application registration unit 203 are supplied to the RDP server unit 200. The startup settings of the applications # 1, # 2,..., #N are stored in the application setting unit 204 as settings # 1, # 2,.

  A setting conversion unit 205 serving as a conversion unit generates settings for the applications # 1, # 2,..., #N based on setting information received from the client terminals 30, 31, and 32 and input to the RDP server unit 200. The generated setting information is stored as corresponding settings # 1, # 2,..., #N of the application setting unit 204. The setting information generation method in the setting conversion unit 205 is stored in the conversion table 206. An example of specific data stored in the conversion table 206 will be described later.

  The connection client information temporary storage unit 210 temporarily stores information related to the connected client terminal when connected to the client terminals 30, 31, and 32. The connection client information temporary storage unit 210 temporarily stores connection client information 207 regarding the client terminal and setting information 208 acquired from the client terminal regarding the connected client terminal.

  The server device 50 is actually configured in the same manner as a general computer, and includes a CPU, a ROM, and a RAM, a storage medium such as a hard disk, and a drive unit that reads data from the recording medium. (Not shown). The CPU as the activation control means reads the program from the ROM or hard disk and controls the server device 50 using the RAM as a work memory. The RDP server unit 200, the application registration unit 203, the application setting unit 204, and the setting conversion unit 205 described above can be configured by programs operating on the CPU.

  The program may be stored in advance in the ROM, or can be acquired from the network 61 by the communication interface 201. You may acquire by reading from recording media, such as DVD and CD-ROM, in a drive part.

  First, the operation of the client terminal alone will be schematically described. As an example, a case where the user activates the television receiver 42 and the client terminal 32 installed in the room 13 in the living room and switches the input of the television receiver 42 to select the output of the client terminal 32. Think. When the client terminal 32 is activated, the control unit 110 generates a display signal for displaying a menu screen. This display signal is output from the display interface 103 and supplied to the television receiver 42. On the screen of the television receiver 42, a menu screen by the client terminal 32 is displayed.

  For example, when an operation for selecting browser activation from the menu screen is performed on the remote control 130 of the client terminal 32, an infrared signal in which a control signal corresponding to the operation is modulated is transmitted from the remote control 130. The infrared signal is received by the operation interface 104 and demodulated, and a control signal is extracted. The control signal is passed from the operation interface 104 to the main control unit 100. The main control unit 100 activates a simple browser function that is an individual function in the function providing unit 101 in accordance with the control signal. The activated simple browser function reads the setting for the browser from the function-specific setting table 106 and starts the operation according to this setting.

  FIG. 4 shows an example of setting information stored in the function-specific setting table 106. The function-specific setting table 106 stores permission attributes set for each individual function of the client terminal 30 as function restriction information and access restriction information, and settings of restriction levels (ratings) according to the contents. Is done.

  FIG. 4A shows an example of permission attributes set for the individual functions of the client terminal 30. For the digital camera connected to the client terminal 30, the image data slide show display function is permitted and the image data storage function is not permitted. Moreover, the simple browsing function of the website is permitted only for a specific URL. That is, access to contents on the Internet such as a website indicated by the URL is restricted. As for the video playback function and DVD playback function, access to the content is permitted depending on the content. Furthermore, the music playback function is permitted. Game functions are not allowed.

  FIG. 4B shows an example of the regulation level according to the content. A rating level is assigned to each category of expressions that should be regulated for content. In the example of FIG. 4B, for each of the three categories of “exposure depiction”, “discrimination term”, and “violent depiction”, the rating is divided into five levels from level 0 having a low rating to level 4 having a high rating level. Is granted. Then, for each category, a level value indicating which rating level is allowed to reproduce the content is set. A setting of level 0 indicates the strictest limit and a setting of level 4 indicates the weakest limit. Content permitted for all categories according to the rating level is permitted.

  A permission attribute as shown in FIG. 4A and a restriction level as shown in FIG. 4B are set for each of the client terminals 30, 31 and 32, and the setting table 106 for each function is set as setting information. To store. As an example, since the room 12 which is a study is considered to be mainly used by adults, the setting information 106 for each function of the client terminal 31 to be installed stores setting information that is more lenient. As another example, the room 13 that is a living room is considered to be unspecified by the user, and therefore, setting information that provides the strongest regulation is stored in the function-specific setting table 106 of the client terminal 32 to be installed. .

  Next, the client operation in RDP at the client terminal 30 will be described. The user uses the server connection mode when using an application that cannot be executed by the client terminal 30 alone, such as a highly functional browser. In the server connection mode, communication with the server device 50 is performed using the RDP via the indoor LAN, and a high-function browser installed in the server device 50 is activated from the client terminal 30 side. When the user selects connection to the server device 50 from the menu screen by the client terminal 30, the RDP client function unit 102 is activated and server connection processing is started.

  FIG. 5 is a flowchart showing an example of processing on the client terminal 30 side when the server is connected according to the first embodiment of the present invention. In the server connection mode, the main control unit 100 of the client terminal 30 activates the RDP client function unit 102. The RDP client function unit 102 refers to the connection destination setting information 107 in the server information storage unit 120. In this example, information of the server devices 50, 51 and 52 is registered as the connection destination setting information 107. In step S <b> 101, the RDP client function unit 102 acquires information on the server device selected as the connection destination from the connection destination setting information 107. This information includes address information on the server device network (indoor LAN 20).

  For example, the server apparatus 50 can be configured to select a server apparatus as a connection destination from the server apparatuses 50, 51, and 52 according to a user operation on the remote controller 130. Not limited to this, a server device as a default connection destination may be set in advance. Here, it is assumed that the server device 50 is set as a default connection destination.

  The RDP client function unit 102 transmits a connection request to the address of the server device 50 acquired in step S101 via the communication interface 105, and starts a connection process with the server device 50 (step S102). In response to the connection request packet, an authentication request is transmitted from the server device 50 to the client terminal 30. This authentication request is received by the client terminal 30 and passed to the RDP client function unit 102. In response to this authentication request, the RDP client function unit 102 refers to the RDP authentication information 108 in the server information storage unit 120 and acquires authentication information for the server device 50. And this authentication information is transmitted to the server apparatus 50, and an authentication process is performed between the server apparatuses 50 (step S103).

  In the next step S104, the authentication result of the server device 50 for this authentication information is determined. If there is a response indicating that the authentication has failed from the server device 50 with respect to this authentication information, the connection processing is interrupted (step S105), and the series of connection processing ends.

  On the other hand, if there is a response indicating that the authentication is successful from the server device 50, the RDP client function unit 102 waits for reception of the next command from the server device 50 (step S106). When a command from the server device 50 is received, the process proceeds to the next step S107, and it is determined whether or not the command is a command for requesting setting information. If it is determined that the command is for requesting setting information, the process proceeds to step S108. In step S <b> 108, the RDP client function unit 102 reads the setting information registered in the function-specific setting table 106 and transmits the read setting information to the server device 50. Then, the process returns to step S106, and reception of the next command from the server device 50 is awaited.

  On the other hand, if it is determined in step S107 that the received command is not a setting information request command, the process proceeds to step S109. In step S109, it is determined whether or not the received command is a command for starting the RDP mode. If it is determined that the received command is not an RDP mode start command, the process returns to step S106, and reception of the next command from the server device 50 is awaited.

  On the other hand, if it is determined in step S109 that the received command is an RDP mode start command, the process proceeds to step S110, and processing in the RDP mode is started. Processing in the RDP mode will be described later.

  FIG. 6 is a flowchart illustrating an example of processing on the server device 50 side corresponding to processing on the client terminal 30 side when the server is connected as described with reference to FIG. In step S201, the RDP server unit 200 receives the connection request packet transmitted from the client terminal 30 in step S102 of FIG. In the next step S202, the RDP server unit 200 transmits an authentication request packet to the client terminal 30 that has transmitted the connection request packet, and executes an authentication phase. When the authentication information transmitted from the client terminal 30 is received in step S103 of FIG. 5, the RDP server unit 200 performs an authentication process according to the authentication information stored in the RDP authentication information storage unit 202 (step S203).

  If it is determined by the authentication process in step S203 that the authentication of the client terminal 30 has failed, the process proceeds to step S204. In step S <b> 204, the RDP server unit 200 notifies the client terminal 30 of the authentication failure and rejects the connection to the server device 50 by the client terminal 30.

  On the other hand, if it is determined by the authentication process in step S203 that the client terminal 30 has been successfully authenticated, the process proceeds to step S205. In step S205, the information of the client terminal 30 acquired at the time of authentication is stored in the connection client information temporary storage unit as connection client information 207.

  The process proceeds to the next step S206, and the RDP server unit 200 transmits a setting information request to the client terminal 30. In step S207, the RDP server unit 200 waits for reception of setting information from the client terminal 30 in response to the transmitted setting information request.

  When the client terminal 30 receives the setting information request transmitted from the server device 50 in step S206, the client terminal 30 reads the setting information registered in the function-specific setting table 106 as described in step S108 of FIG. Send to. When the RDP server unit 200 receives the setting information transmitted from the client terminal 30, the RDP server unit 200 shifts the process to step S208. In step S208, the RDP server unit 200 registers the received setting information as setting information 208 in the connection client information temporary storage unit 210.

  In the next step S209, the setting conversion unit 205 stores the setting information of each application # 1, # 2,..., #N registered in the application registration unit 203 based on the registered setting information 208 according to the conversion table 206. Generate. Then, the generated setting information of each application # 1, # 2,..., #N is associated with the client terminal 30 with respect to the corresponding setting units # 1, # 2,. To set.

  In the next step S210, the RDP server unit 200 creates server menu screen information for selecting and starting each application # 1, # 2,..., #N from the client terminal 30 side. Then, the server menu screen information is transmitted to the client terminal 30 via the communication interface 201. Thereafter, the RDP server unit 200 shifts to a menu mode that accepts a command from the client terminal 30 according to a user operation.

  If the setting information cannot be received from the client terminal 30 within, for example, a predetermined time in step S207 described above, the process proceeds to step S210.

  FIG. 7 shows an exemplary configuration of the conversion table 206. As illustrated in FIG. 7, the conversion table 206 stores the correspondence between individual functions local to the client terminal 30 and server applications # 1, # 2,..., #N installed in the server device 50. .

  In the example of FIG. 7, the camera image slide show function and the camera image storage function, which are one of the individual functions of the client terminal 30, are associated with the high-function album software of the server device 50. In addition, a web browsing function that is one of the individual functions of the client terminal 30 is associated with the high-functional browser software of the server device 50. Furthermore, a moving image playback function and a music playback function, which are one of the individual functions of the client terminal 30, are associated with the high-performance media player software of the server device 50. Furthermore, a DVD playback function that is one of the individual functions of the client terminal 30 is associated with the DVD player software of the server device 50. In addition, a game function that is one of the individual functions of the client terminal 30 is associated with the game function software of the server device 50.

  In the example of FIG. 7, it is assumed that the television recording software and the music download software among the server applications installed in the server device 50 do not have functions corresponding to the client terminals 30, 31, and 32.

  In step S209 described above, based on the information stored in the conversion table 206, the restriction setting for the individual function local to the client terminal 30 is reflected in the restriction setting of the corresponding server application.

  FIG. 8 shows an example of setting of the server application generated in step S209. For the high-performance album software that is one of the server applications, the camera image slideshow function is permitted, but the image storage function is set to disallowed. Also, content editing and uploading to the network 61 are not set because there is no corresponding local function setting on the client terminal 30 side.

  As described above, whether or not activation is permitted is set for each server application based on the setting information read and transmitted from the function-specific setting table 106 in the client terminal 30 and the conversion table 206 of the server device 50. The The server device 50 generates this server application setting for each of the server applications # 1, # 2,..., #N for each client terminal connected to the server device 50 and registers it in the application setting unit 204. For the functions that have not been set, the default restriction setting values of the server applications # 1, # 2,..., #N can be used.

  When the processing by the client terminal 30 and the server device 50 is completed as described above, the server applications # 1, # 2,..., #N installed in the server 51 can be activated and operated from the client terminal 30. .

  FIG. 9 is a flowchart illustrating an example of processing on the server device 50 side when the client terminal 30 instructs the server device 50 to start the server applications # 1, # 2,..., #N according to the server menu screen. It is.

  Prior to the processing of the flowchart of FIG. 9, the server device 50 and the client terminal 30 are connected by RDP, and the server menu screen generated by the server device 50 is transmitted to the client terminal 30 to be transmitted to the television receiver 40. Is displayed. The server menu screen displays a list of server applications # 1, # 2,..., #N that can be started from the client terminal 30, for example.

  The user operates the remote controller 130 according to the server menu screen to select a server application to be activated. The RDP client function unit 102 transmits a server application activation request selected by a user operation to the server device 50.

  In step S <b> 301, the RDP server unit 200 of the server device 50 transmits a request for starting server applications # 1, # 2,..., #N transmitted from the client terminal 30, or disconnection that disconnects the connection with the server device 50. Wait for the request. If a disconnect request is received, the process proceeds to step S313.

  If the activation request for the server applications # 1, # 2,..., #N is received in step S301, the process proceeds to step S302. In step S302, it is determined which of the server applications # 1, # 2,. Here, for the sake of simplicity, description will be made assuming that there are three types of server applications: high-function album software, high-function browser software, and high-function media player.

  If it is determined that the activation of the high function album software is requested by the activation request, the RDP server unit 200 reads setting information corresponding to the client terminal 30 of the high function album software from the application setting unit 204 (step S303). Then, based on the read setting information, it is determined whether or not the client terminal 30 is permitted to start the high-function album software (step S304).

  If it is determined that activation is not permitted, the process returns to step S301. At this time, a display signal for displaying a screen for notifying the user that activation is not permitted can be generated and transmitted to the client terminal 30.

  On the other hand, if it is determined in step S303 that activation of the high-performance album software is permitted, the process proceeds to step S305. In step S305, the RDP server unit 200 activates the high-performance album software registered as a server application in the application registration unit 203 in accordance with the activation request.

  The RDP server unit 200 transmits the screen image output by the activated high-performance album software to the client terminal 30 via the communication interface 201. The client terminal 30 receives this screen image at the communication interface 105. The received screen image is transferred to the control unit 110 and is supplied to the display interface 103 as a display control signal. The display interface 103 converts the display control signal into a display signal and supplies the display signal to the television receiver 40, for example.

  Note that, according to the settings of the server application illustrated in FIG. 8, among the functions of the high-function album software, the client terminal 30 is permitted to start the camera image slide show function, and the camera image storage function is not permitted. ing. Therefore, among the functions of the activated advanced album software, the use of the camera image storage function is not permitted, and the function of uploading the camera image data to, for example, the server device 50 or the network 61 cannot be used.

  If it is determined in step S302 that activation of the advanced browser software is requested, the process proceeds to step S306. In step S306, the RDP server unit 200 reads setting information corresponding to the client terminal 30 of the high-functional browser software from the application setting unit 204. Then, based on the read setting information, it is determined whether or not the client terminal 30 is permitted to start the high-functional browser software (step S307). If activation is not permitted, the process returns to step S301.

  On the other hand, if it is determined that the activation of the advanced browser software is permitted, the process proceeds to step S308. In step S308, the RDP server unit 200 activates high-functional browser software registered as a server application in the application registration unit 203 in accordance with the activation request.

  The RDP server unit 200 transmits the screen image output by the activated advanced browser software to the client terminal 30 via the communication interface 201. The client terminal 30 receives this screen image by the communication interface 105 and displays it on the television receiver 40, for example.

  Note that, according to the setting of the server application illustrated in FIG. 8, only the connection to a specific URL is permitted for the client terminal 30 among the functions of the high-functional browser software. For example, the specific URL is registered in advance for “favorite” or “bookmark” of the high-functional browser software installed in the server device 50, and only the URL registered in the “favorite” or “bookmark” is registered. It is conceivable to be able to connect.

  If it is determined in step S302 that activation of the high function media player is requested, the process proceeds to step S309. In step S309, the RDP server unit 200 reads setting information corresponding to the client terminal 30 of the high-performance media player software from the application setting unit 204. Then, based on the read setting information, it is determined whether or not the client terminal 30 is permitted to start the high-function media player software (step S310). If activation is not permitted, the process returns to step S301.

  On the other hand, if it is determined that activation of the high-performance media player software is permitted, the process proceeds to step S311. In step S311, the RDP server unit 200 activates the high-performance media player software registered as a server application in the application registration unit 203 in accordance with the activation request.

  The RDP server unit 200 transmits the screen image output by the activated high-performance media player software to the client terminal 30 via the communication interface 201. The client terminal 30 receives this screen image by the communication interface 105 and displays it on the television receiver 40, for example.

  Note that according to the setting of the server application illustrated in FIG. 8, music playback by the high-performance media player software is permitted unconditionally. On the other hand, for moving image reproduction, it is determined whether or not reproduction is permitted according to the rating assigned to the content.

  When the server application started in step S305, step S308, or step S311 is terminated (step S312), the process returns to step S301. The server application is terminated in accordance with, for example, a termination instruction operation on the remote controller 130 of the client terminal 30.

  If a disconnection request for disconnecting the connection with the server device 50 is received in step S301 and step S313, the process proceeds to step S314, and a process for disconnecting the connection of the client terminal 30 to the server device 50 is performed. When the connection with the client terminal 30 is disconnected, the process proceeds to step S315, and the setting information 208 in the connection client information temporary storage unit 210 is cleared. Then, in the next step S316, the connection client information 207 in the connection client information temporary storage unit 210 is cleared, and a series of processing ends.

  As described above, according to the first embodiment of the present invention, the restriction setting information set for each individual function on the client terminal side is transmitted to the server device when connected to the server device. Then, the server device converts the received restriction setting information so as to correspond to the server application installed in the server device, and applies it to the server application requested to be activated. Therefore, even when a server application mounted on the server device is started from the client terminal, the restriction setting set for the client terminal can be reflected in the server application.

<Second Embodiment>
Next, a second embodiment of the present invention will be described. In the second embodiment, more general profile information is set for the setting information for the individual functions of the client terminal according to the first embodiment. FIG. 10 shows an exemplary configuration of the client terminal 300 according to the second embodiment. In the client terminal 300 according to the second embodiment, a profile storage unit 111 that stores profile information is added to the client terminal 30 according to the first embodiment described with reference to FIG. In FIG. 10, the same reference numerals are given to the portions common to the configuration of FIG. 2 described above, and detailed description thereof is omitted.

  Similarly, FIG. 11 shows a configuration of an example of the server device 500 according to the second embodiment. In the server apparatus 500 according to the second embodiment, profile information 209 is added to the connection client information temporary storage unit 210 of the server apparatus 50 according to the first embodiment described with reference to FIG. A conversion table 211 is added to the conversion table 206. In FIG. 11, the same reference numerals are given to the portions common to the configuration of FIG. 3 described above, and detailed description thereof is omitted.

  The client terminal 300 according to the second embodiment can be appropriately applied to the client terminals 30, 31 and 32 in the system shown in FIG. Similarly, the server device 500 can be appropriately applied to the server devices 50, 51 and 52.

  FIG. 12 shows an example of profile information stored in the profile storage unit 111 of the client terminal 300. As general-purpose profile information, it is conceivable to use age or information according to age. In the example of FIG. 12, there are four levels of “adult”, “junior high school student and high school student”, “elementary school student” and “preschool child”. Define. This profile information is used as supplementary information for the setting information of the server application to be activated in the server device 500.

  As an example, when the age of a user who uses a client terminal is assumed, profile information corresponding to the age is registered in the client terminal. As a more specific example, referring to FIG. 1, when the client terminal 300 is installed in the room 11 which is a child room, “elementary school student” or “high school student and junior high school student” is registered as profile information. When the client terminal 300 is installed in the room 12 which is a study, “adult” is registered as profile information. In addition, when the client terminal 300 is installed in the room 13 which is a living room where users of a plurality of age groups can freely enter and exit, “elementary school students” and “preschool children” are registered as profile information.

  FIG. 13 is a flowchart illustrating an example of processing on the server device 500 side corresponding to processing on the client terminal 300 side when the server is connected according to the second embodiment. Note that the processing on the client terminal 300 side is not different from the processing in the client terminal 30 according to the first embodiment described with reference to FIG. 5, and thus description thereof is omitted to avoid complication. .

  In the flowchart of FIG. 13, the processing from step S <b> 401 to step S <b> 409 is not different from the processing according to the first embodiment described with reference to FIG. 6, and the description here is omitted to avoid complexity. . If the setting information is not received from the client terminal 300 in step S407, or if the server application setting information is generated in step S409, the process proceeds to step S410.

  In step S410, it is determined whether there is an unset item in the server application setting information. If it is determined that there are no unset items, the process proceeds to step S415, and a server menu screen is generated in the same manner as in step S210 of FIG.

  On the other hand, if it is determined in step S410 that there is an unset item, the process proceeds to step S411. In the example of FIG. 8 described above, the content editing function, the network upload function, the television broadcast recording software, and the music download software function in the high-performance album software are not set.

  In step S411, the client terminal 300 is requested for profile information. Upon receiving this request, the client terminal 300 reads profile information from the profile storage unit 111 and transmits it to the server device 500. When the server apparatus 500 receives the profile information from the client terminal 300 (step S412), the server apparatus 500 shifts the process to step S413. For example, if the server device 500 cannot receive the profile information from the client terminal 300 within a predetermined time, the server device 500 shifts the processing to step S415.

  In step S413, the server apparatus 500 registers the received profile information as profile information 209 in the connection client information temporary storage unit 210A.

  In the next step S414, the setting conversion unit 205 performs setting for unset items. The setting conversion unit 205 sets the settings for the unset items in the setting information of each application # 1, # 2,..., #N registered in the application registration unit 203 based on the registered profile information 209 according to the conversion table 211. Do.

  FIG. 14A shows the contents of an example of the conversion table 211 for creating server application setting information from the profile information 209. As illustrated in FIG. 14A, the conversion table 211 correlates whether or not to permit the function of the unset item in the setting information of the server application according to age or information according to age.

  In the example of FIG. 14A, settings corresponding to the profile information 209 are made for the television broadcast recording software and music download software in which unset items exist. That is, “adult”, “high school student and junior high school student”, “elementary school student”, and “preschool child” are set for the software in which these unset items exist, corresponding to the profile information 209. For example, when the profile information 209 is “elementary school student”, the television broadcast recording software function is permitted depending on the content. Also, the music download software function is not allowed.

  FIG. 14B shows an example of the regulation level according to the content. Similar to FIG. 4B described above, a rating level is set for each age or information according to age for each category of expressions that should be regulated for content. In the example of FIG. 14B, when the profile information 209 is “elementary school student”, the rating levels of “exposure expression”, “discrimination term”, and “violent expression” are “0”, “1”, “ 1 ”is set and a strong regulation is applied. When the profile information 209 is “adult”, the rating level is all “4” and no restriction is imposed. When the profile information 209 is “preschool child”, the rating level is “0” in all categories, and the strongest restriction is applied.

  As described above, according to the second embodiment of the present invention, the profile information including the more general information for the user who is assumed to use the client terminal is used to set the server application whose setting information is not set. Generate configuration information. Therefore, even when a server application installed in the server device from the client terminal and having no setting information is activated, the activation of the server application can be regulated with an appropriate rating.

  In the above description, as illustrated in FIG. 12 as an example of profile information, age or information according to age is used, but the profile information is not limited to this. For example, as illustrated in FIG. 15, gender and age can be set as profile information.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. The third embodiment is an example in which a server application can be additionally registered with a server device.

Not limited to this, it is also conceivable that what is already installed as a general application in the server apparatus 510 is registered as a server application.

  The new registration unit 220 performs processing for registering a new application as a server application with respect to the application registration unit 203. A new application is stored in the application registration unit 203, and a menu for starting the new application is added to the server menu generated by the RDP server unit 200 (step S501).

  In the next step S <b> 502, the application registration unit 203 registers default setting values in the application setting unit 204. This default value is used as setting information common to all client terminals when the setting information 208 cannot be obtained from the client terminal, or when setting for each client terminal is not possible, such as when there is no corresponding setting value.

  In step S503, it is determined whether the newly added server application has a conversion table corresponding to the setting information for the individual function on the client terminal side. For example, the new registration unit 220 checks whether the newly added server application has information indicating the correspondence between the function of the server application and the individual function on the client terminal side. If it is determined that the new server application has the conversion table, the conversion table is additionally registered in the conversion table 206 via the setting conversion unit 205, and the series of processing ends. On the other hand, if it is determined that the new server application does not have the conversion table, the series of processing is terminated as it is.
