Description
- The present application claims priority from Japanese Patent Application No. JP 2008-321873 filed in the Japanese Patent Office on Dec. 18, 2008, the entire content of which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to an operation apparatus capable of communicating, via a wireless medium, with an electronic apparatus capable of communicating, via a network, with an accumulation apparatus capable of accumulating contents, and to a content parental lock setting method by the operation apparatus. The present invention also relates to an electronic apparatus capable of communicating, via a network, with at least one accumulation apparatus capable of accumulating contents, and communicating with the operation apparatus via a wireless medium.
- 2. Description of the Related Art
- In recent years, based on a DLNA (digital living network alliance), there has been structured a system that mutually connects, for example, digital AV (audiovisual) equipment or a PC (personal computer) with another in a home network environment as a local area network. With this structure, a content obtained through a broad band can be shared among family members and viewed in a home network environment, for example. That is, contents accumulated in various server apparatuses can be viewed by using various client apparatuses. As a result, for example, a situation in which a minor can easily view various contents beyond eyeshot of a parent or guardian may occur.
- In view of this, there has been developed a technique in which a parental lock is set with respect to a content including an inappropriate image or audio that may give a bad influence to a minor (see, for example, Japanese Patent Application Laid-open No. 2008-236153 (paragraph 0026, FIG. 2) (hereinafter, referred to as Patent Document 1)). With the technique disclosed in
Patent Document 1, restricted information for a content as a target of a parental lock setting is registered in a table for a parental lock, which is stored in a server apparatus. Upon reception of a content obtainment request from a client apparatus, the server apparatus judges whether restricted information is set for the content requested. When the restricted information is set for the content requested, the server apparatus does not transfer the content to the client apparatus. - With the technique disclosed in
Patent document 1, a table for setting the parental lock for each server apparatus is created. Accordingly, in a case where there are a plurality of server apparatuses in a home network, it is necessary to set a parental lock with respect to a content for each server apparatus. This is a troublesome operation for a user. Further, for example, in a case where a minor has a PC in his/her own room, it may be substantially difficult for a parent or guardian to set a parental lock. - In view of the above-mentioned circumstances, it is desirable to provide an operation apparatus capable of communicating, via a wireless medium, with an electronic apparatus capable of communicating, via a network, with an accumulation apparatus capable of accumulating contents, and a parental lock setting method for contents by the operation apparatus. It is also desirable to provide an electronic apparatus capable of communicating, via a network, with at least one accumulation apparatus capable of accumulating contents and communicating, via a wireless medium, with the operation apparatus.
- According to an embodiment of the present invention, there is provided an operation apparatus including a communication section, a content selection section, a release key setting section, a storage section, and a parental lock notification section. The communication section communicates with an electronic apparatus capable of communicating, through a first transmission medium, with an accumulation apparatus capable of accumulating contents, the communication section communicating with the electronic apparatus through a second transmission medium. The content selection section selects a content to which a parental lock is to be set from among the contents accumulated in the accumulation apparatus. The release key setting section sets a key for releasing the parental lock for the content selected. The storage section associates identification information of the content selected with the key set by the release key setting section and stores the identification information and the key associated with each other. The parental lock notification section notifies, through the electronic apparatus by using the communication section, the accumulation apparatus in which the content is accumulated of the identification information of the content to which the parental lock is set.
- According to the embodiment of the present invention, the storage section of the operation apparatus associates the identification information of the content with the key for releasing the parental lock for the content and stores the identification information and the key associated with each other. As a result, it becomes possible for the operation apparatus to unify and manage the data related to the plurality of accumulation apparatuses.
- In the embodiment, the operation apparatus further includes a name list obtainment section, an accumulation apparatus selection section, a content list obtainment section, and a list display section. The name list obtainment section requests to obtain a list of names of the accumulation apparatuses connected to the first transmission medium and obtains the list from the electronic apparatus by using the communication section. The accumulation apparatus selection section causes a user to select a name from the obtained list of the names of the accumulation apparatuses. The content list obtainment section requests the electronic apparatus by using the communication section to obtain a list of contents accumulated in the accumulation apparatus corresponding to the name selected and obtains the list of the contents. The list display section displays the obtained list of the contents to the user. The content selection section selects a content to which the parental lock is to be set from the displayed list of the contents.
- According to the embodiment of the present invention, the user can obtain the list of the contents of each of the plurality of accumulation apparatuses connected to the network not from each of the plurality of accumulation apparatuses but from one operation apparatus.
- In the embodiment, the parental lock notification section gives the electronic apparatus a notification including the identification information of the content and identification information of the accumulation apparatus that is a notification destination, to notify, through the electronic apparatus by using the communication section, the accumulation apparatus in which the content is accumulated of the identification information of the content to which the parental lock is set.
- According to the embodiment of the present invention, it is possible to transmit the identification information of the content to any accumulation apparatus by using the one operation apparatus.
- In the embodiment, the content list obtainment section transmits, to the electronic apparatus, a content list obtainment request including the identification information of the accumulation apparatus corresponding to the name selected, to request the electronic apparatus by using the communication section to obtain the list of the contents accumulated in the accumulation apparatus corresponding to the name selected and obtain the list of the contents.
- According to the embodiment of the present invention, it is possible to obtain the list of the contents of any accumulation apparatus by using the one operation apparatus.
- In the embodiment, the first transmission medium is a network, and the second transmission medium is a transmission medium independent of the network.
- According to the embodiment of the present invention, the two-way communication is realized not between the operation apparatus and one accumulation apparatus but between the operation apparatus and the network.
- In the embodiment, the operation apparatus further includes a parental lock release content selection section, a release key input section, and a parental lock release notification section. The parental lock release content selection section selects a content from which the parental lock is released. The release key input section causes the user to input a key for releasing the parental lock for the content selected. The parental lock release notification section notifies, when the key that is stored in the storage section with the key being associated with the content selected and the key that is input by the release key input section coincide, the accumulation apparatus in which the content is accumulated of a release of the parental lock for the content through the electronic apparatus by using the communication section.

Upon reception of the content list obtainment request C6, the contentlist processing section 631 sets a content list table to the contentlist storage section 632. The contentlist processing section 631 extracts the content IDs and the titles of the programs of all the contents stored in the contentdata storage section 624 from SI (service information) information. The contentlist processing section 631 registers the extracted information in a content list table 720 provided for the content list storage section 632 (Step S116). - As shown in
FIG. 12 , the content list table 720 is constituted of acontent ID field 721, aprogram title field 722, and a parentallock flag field 733. Information items registered in thosefields server apparatuses 600 each receive the SI information and always have latest SI information. The SI information includes various information items relating to the content, such as a content ID, a title of a program, a distribution time, and details of a program. - Next, the content
list processing section 631 of theserver apparatus 600 a creates a content list including the content IDs and the titles of the programs of all the contents in the content list table 720. The contentlist processing section 631 of theserver apparatus 600 a transmits the response S2 including the created content list to theclient apparatus 500 via the home network 200 (Step S117). - The
list relay section 543 of theclient apparatus 500 receives the response S2 including the content list from theserver apparatus 600 a via the home network 200 (Step S118). Thelist relay section 543 transmits, to theremote controller 400 by using theoptical communication section 511, the response S2 including the content list received from theserver apparatus 600 a as the response C7 (Step S119). - The content
list processing section 413 of theremote controller 400 receives the response C7 including the content list from thelist relay section 543 of the client apparatus by using the optical communication section 402 (Step S120). The contentlist processing section 413 sets a content management table 730 to the contentlist storage section 414 and registers, in the content management table 730, the content IDs and the titles of the programs in the content list included in the response C7 received from the client apparatus 500 (Step S121). - As shown in
FIG. 13 , the content management table 730 is constituted of acontent ID field 731, aprogram title field 732, a parentallock flag field 733, a parentalunlock code field 734, and an apparatus ID filed 736. - The
UI processing section 412 of theremote controller 400 reads all the program titles registered in the content management table 730 from the content list storage section 414 (R8). TheUI processing section 412 creates display data of acontent selection screen 810 including the content list of all the program titles read and supplies a display request R9 including the display data of thecontent selection screen 810 to the display section 404 (Step S122). As a result, thecontent selection screen 810 is displayed on the screen of thedisplay section 404. - As shown in
FIG. 14 , thecontent selection screen 810 serves as a user interface for displaying a list of the program titles of all the contents accumulated in the server apparatus selected by the user and causing the user to select any one from the contents. - The user uses the
input operation section 405 to select a content with respect to which the user wants to perform reproduction or set the parental lock from among the program titles displayed on thecontent selection screen 810. Theinput operation section 405 supplies selection information R10 of the program title to the UI processing section 412 (Step S123). - It should be noted that in this embodiment, the
content selection screen 810 or various screens (described below) are displayed on the display screen of theremote controller 400, but where to display those screens is not limited to this case. Those screens may be displayed on the display device of thedisplay section 506 of theclient apparatus 500. - Upon reception of the selection information R10 from the
input operation section 405, theUI processing section 412 creates display data of a menu screen 801 (shown inFIG. 15 ) as a list of processings that can be performed on the content of the program title selected. Further, theUI processing section 412 supplies a display request R11 including the display data of themenu screen 801 to the display section 404 (Step S124). As a result, themenu screen 801 is displayed on the screen of thedisplay section 404. - As shown in
FIG. 15 , themenu screen 801 serves as a user interface for displaying a list of processing commands that can be executed with respect to the selected content and causing the user to select a processing command that has to be executed with respect to the selected content. On themenu screen 801, character strings that indicate the processing commands to be executed with respect to the content, such as “reproduction”, “parental lock”, and “move”, are displayed. The “reproduction” refers to a processing of reproducing data of the content held by theserver apparatus 600 by theclient apparatus 500, and the “parental lock” refers to a processing of setting the parental lock with respect to the content. The “move” refers to a processing of moving the content from oneserver apparatus 600 to another. - A description will be given on a case where the execution of the processing of the “parental lock” is specified to the
menu screen 801 by the user by using theinput operation section 405. In this case, theinput operation section 405 supplies selection information R12 of the processing of the “parental lock” to the UI processing section 412 (Step S125). - Upon reception of the selection information R12 of the processing of the “parental lock” from the
input operation section 405, theUI processing section 412 subsequently creates display data of a parental unlock code input screen 802 (shown inFIG. 16 ) and supplies a display request R13 including the display data to thedisplay section 404. As a result, the parental unlockcode input screen 802 is displayed on the screen of thedisplay section 404. - As shown in
FIG. 16 , the parental unlockcode input screen 802 serves as a user interface for causing the user to input a code necessary for releasing the parental lock that is set to the content. On the parental unlockcode input screen 802, a message for guiding the user, e.g., “input parental unlock code”, input boxes of, e.g., a four-digit parental unlock code, and the like are displayed. - The user references the parental unlock
code input screen 802 displayed on thedisplay section 404 and inputs the parental unlock code by using theinput operation section 405. Theinput operation section 405 supplies a parental unlock code R14 input by the user to theUI processing section 412. - Upon reception of the parental unlock code R14 from the
input operation section 405, theUI processing section 412 causes the parental unlock code to be displayed on the parental unlockcode input screen 802 of the display section 404 (Step S126). - Further, the
UI processing section 412 supplies a parental lock setting request including the parental unlock code to the parentallock processing section 415. Upon reception of the parental lock setting request from theUI processing section 412, the parentallock processing section 415 performs registration in the content management table 730 stored in the contentlist storage section 414 as follows. - For example, as shown in
FIG. 17 , the parentallock processing section 415 sets a value corresponding to “with parental lock” as the parental lock flag to the parentallock flag field 733 that belongs to arecord 735 in the content management table 730, and registers a parental unlock code in the parentalunlock code field 734 that also belongs to the record 735 (Step S127). - When the registration in the content management table 730 is over, the parental
lock processing section 415 transmits, to theclient apparatus 500 by using theoptical communication section 402, the parental lock setting notification R17 including the set of the apparatus ID and the content ID to which the parental lock is set (Step S128). - The
list relay section 543 of theclient apparatus 500 receives the parental lock setting notification R17 including the set of the apparatus ID and the content ID to which the parental lock is set from theremote controller 400 by using the optical communication section 511 (Step S129). Upon reception of the parental lock setting notification R17, thelist relay section 543 transmits the parental lock setting request C8 including the content ID included in the parental lock setting notification R17 to theserver apparatus 600 a corresponding to the apparatus ID included in the parental lock setting notification R17 (Step S130). - Upon reception of the parental lock setting request C8 from the
client apparatus 500, the parental lock processing section 633 of theserver apparatus 600 a updates the content list table 720 stored in the contentlist storage section 632 based on the parental lock setting request C8 (Step S131). - Specifically, as shown in
FIG. 18 , into the parentallock flag field 733 corresponding to the content ID included in the parental lock setting request C8, a value corresponding to “with parental lock” is set as the parental lock flag. - After that, the parental lock processing section 633 transmits the parental lock setting completion notification S3 to the
client apparatus 500 via the home network 200 (Step S132). - Upon reception of the parental lock setting completion notification S3 from the
server apparatus 600 a (Step S133), thelist relay section 543 of theclient apparatus 500 transmits the parental lock setting completion notification C9 to theremote controller 400 by using the optical communication section 511 (Step S134). - Upon reception of the parental lock setting completion notification C9 from the client apparatus 500 (Step S135), the parental
lock processing section 415 of theremote controller 400 outputs the parental lock setting completion notification R18 to theUI processing section 412. - The
UI processing section 412 receives the parental lock setting completion notification R18 from the parentallock processing section 415. TheUI processing section 412 creates display data of the content corresponding to the content ID included in the parental lock setting completion notification R18 and supplies the display data to the display section 404 (Step S136). It should be noted that in the display data, a graphic symbol indicating that the parental lock is already set is added to the column in which the program title is displayed on thecontent selection screen 810. As a result, thecontent selection screen 810 displayed on thedisplay section 404 is updated as shown inFIG. 19 , for example. In this way, agraphic symbol 811 indicating that the parental lock is already set is added to the column of displaying the program titles corresponding to the content to which the parental lock is set. The above is the description on the parental lock setting with respect to the specific content. - In a case where the parental lock is subsequently set with respect to another
server apparatus 600 b, the process of Steps S112 to S136 only has to be performed again. - That is, the user references the
server selection screen 800 displayed on thedisplay section 404 and selects theserver apparatus 600 b by using theinput operation section 405. For example, in a case where the user selects a server name “Living Room 1” by using theinput operation section 405, theinput operation section 405 supplies the server selection request R5 including selection information of a processing for the server name “Living Room 1” selected by the user to theUI processing section 412. Upon reception of the server selection request R5 from theinput operation section 405, theUI processing section 412 supplies the server selection request R5 to the content list processing section 413 (Step S112). - Upon reception of the server selection request R5 from the
UI processing section 412, the contentlist processing section 413 reads an apparatus ID of theserver apparatus 600 b corresponding to the server name from the server list table 710 based on the selection information of the server name included in the server selection request R5. The contentlist processing section 413 transmits the content list obtainment request R6 including the readapparatus ID 701 to theclient apparatus 500 by using the optical communication section 511 (Step S113). - The
list relay section 543 of theclient apparatus 500 receives the content list obtainment request R6 from the contentlist processing section 413 of the remote controller 400 (Step S114). Thelist relay section 543 transmits, via thehome network 200, the content list obtainment request C6 to theserver apparatus 600 b to which the apparatus ID included in the content list obtainment request R6 is previously assigned (Step S115). - The content
list processing section 631 of theserver apparatus 600 b receives the content list obtainment request C6 from thelist relay section 543 of theclient apparatus 500 via thehome network 200. Subsequent operations are the same as those of Steps S116 to S136 described above. - By the setting operation of the parental lock described above, the content
list storage section 414 of theremote controller 400 holds the content management table 730 in which the information (such as the program titles) on the contents accumulated in each of theserver apparatuses 600, the parental lock flag indicating whether the parental lock is set, and the code for releasing the parental lock are registered. That is, it is possible to unify and manage the information relating to the parental lock setting with respect to the contents accumulated in theserver apparatuses 600 by theremote controller 400, with the result that convenience for the user is improved. In addition, in a case where a minor has theserver apparatus 600 in his/her own room, it is also possible to remotely set the parental lock by a parent or guardian by using theremote controller 400, for example. - It should be noted that in this embodiment, only the content
list storage section 414 of theremote controller 400 holds the content management table 730 in which the parental unlock code is registered. On the other hand, in the content list table 720 stored in the contentlist storage section 632 of theserver apparatus 600, the parental unlock code is not registered, and a flag indicating whether the parental lock is set is only set. However, the present invention is not limited to this example. Another content list table 720 may be created, and the parental unlock code may be corresponded to a flag and registered in the content list table 720. In this case, the user of theserver apparatus 600 is not allowed to access the parental unlock code registered in the content list table 720 created. -
FIG. 20 shows a structure of the content list table 720 used in this case. As shown inFIG. 20 , the content list table 720 has a structure that includes theparental unlock field 734 in addition to thecontent ID field 721, theprogram title field 722, and the parentallock flag field 733. - In Step S128, when the registration in the content management table 730 is over, the parental
lock processing section 415 transmits the parental lock setting notification R17 including the set of the apparatus ID, the content ID, with/without the parental lock, and the parental unlock code, as the information newly registered in the content management table 730. - In Step S129, the
list relay section 543 of theclient apparatus 500 receives the parental lock setting notification R17 including the set from the parentallock processing section 415 of theremote controller 400. - In Step S130, the
list relay section 543 transmits the parental lock setting request C8 including the set of the content ID, the parental lock, and the parental unlock code that are included in the parental lock setting notification R17 to theserver apparatus 600 a corresponding to the apparatus ID included in the parental lock setting notification R17 received. - As described above, by registering the parental unlock code in the content list table 720 stored in the content
list storage section 632 of theserver apparatus 600, theserver apparatus 600 can hold the parental unlock code for backup. Accordingly, it is possible not only to unify and manage the data relating to the parental lock setting or the like in the plurality ofserver apparatuses 600 by using theremote controller 400, but also to prevent the parental unlock code from being lost because of losing theremote controller 400. - The backup parental unlock code held in the
server apparatus 600 is read from the content list table 720 by inputting a command and a password for referencing the parental unlock code to theserver apparatus 600 or theclient apparatus 500 by the user, for example. The parental unlock code read is displayed on thedisplay section 506 of theclient apparatus 500 or thedisplay section 607 of theserver apparatus 600. By referencing the parental unlock code displayed, the user can reregister the parental unlock code to theremote controller 400. - It should be noted that in this embodiment, the example in which one
remote controller 400 is used is described, but the present invention is not limited to this. A plurality of remote controllers (400 a, 400 b) that respectively perform the two-way communication with a plurality ofclient apparatuses 500 connected to thehome network 200 may be provided. In this case, the details of the update of the content management table 730 of theremote controller 400 a may be transmitted to theremote controller 400 b through theclient apparatus 500 and reflected to the content management table 730 of theremote controller 400 b. - Thus, for example, when the parental lock setting operation is performed by using the
remote controller 400 a of the parent or guardian, the parental lock information can be promptly set to theremote controller 400 b of the minor, which improves the convenience for the user. - In addition, one of the remote controllers (400 a or 400 b) holds a backup parental unlock code of the other remote controller (400 a or 400 b), which is useful as a prevention measure of losing the parental unlock code due to losing of one of the remote controllers (400 a or 400 b).
- (Setting Release Operation with Respect to Content to which Parental Lock is Set)
- Next, a setting release operation of the parental lock will be described with reference to
FIG. 21 .FIG. 21 is a flowchart showing the setting release operation of the parental lock by thecontent management system 100. - As shown in
FIG. 21 , the operations of Steps S101 to S124 are performed. Let us assume that in Step S124, the user selects the execution of the processing of the “parental lock” by using theinput operation section 405 on themenu screen 801 displayed on the screen of thedisplay section 404 of theremote controller 400. Theinput operation section 405 supplies, to theUI processing section 412, the selection information R12 of the processing of the “parental lock” selected by the user (Step S201). - Upon reception of the selection information R12 of the “parental lock” processing from the
input operation section 405, theUI processing section 412 creates the display data of the parental unlock code input screen 802 (shown inFIG. 16 ) based on the selection information R12 and supplies the display request R13 including the display data to thedisplay section 404. As a result, the parental unlockcode input screen 802 is displayed on the screen of thedisplay section 404. - The user references the parental unlock
code input screen 802 displayed on thedisplay section 404 and inputs the parental unlock code by using theinput operation section 405. Theinput operation section 405 supplies the parental unlock code R14 input by the user to theUI processing section 412. - Upon reception of the parental unlock code R14 from the
input operation section 405, theUI processing section 412 causes the input parental unlock code to be displayed for confirmation on the parental unlockcode input screen 802 of thedisplay section 404. The user confirms whether the parental unlock code displayed is correct. When the parental unlock code is correct, the user presses a specific key of theinput operation section 405 and inputs the fact that the parental unlock code to be input is decided (Step S202). - The
input operation section 405 notifies theUI processing section 412 of the decision. In response to this notification, theUI processing section 412 supplies, to the parentallock processing section 415, a parental lock release request R15 including the input parental unlock code and the content ID corresponding to the content on which the release of the parental lock is decided to be performed by the user in Step S123. Upon reception of the parental lock release request R15, the parentallock processing section 415 reads the parental unlock code registered in the parental unlock code field 734 (see,FIG. 17 ) in the corresponding record from the content management table 730 based on the content ID included in the parental lock release request R15. Then, the parentallock processing section 415 compares the parental unlock code included in the input parental lock release request R15 with the parental unlock code read from the parentalunlock code field 734 of the content management table 730 (Step S203). - When it is judged that both the parental unlock codes coincide (Yes in Step S204), the parental
lock processing section 415 updates the value of the parental lock flag set in the parentallock flag field 733 in the corresponding record from “with parental lock” to “without parental lock”. In addition, the parentallock processing section 415 deletes the parental unlock code corresponded to the parental lock flag (Step S205). - When the setting of the parental lock is released as described above, the parental
lock processing section 415 supplies, to theUI processing section 412, a parental lock release completion notification R21 including the content ID of the content that has been subjected to the release of the parental lock. Upon reception of the parental lock release completion notification R21 from the parentallock processing section 415, theUI processing section 412 supplies, to thedisplay section 404, a parental lock release display request R22 including the content ID that has been subjected to the release of the parental lock setting. Upon reception of the parental lock release display request R22 from theUI processing section 412, thedisplay section 404 deletes thegraphic symbol 811 indicating that the parental lock is already set on the display list of the program title corresponding to the content that has been subjected to the release of the parental lock setting (Step S206). - On the other hand, in Step S204, if it is judged that the parental unlock codes do not coincide (No in Step S204), the parental
lock processing section 415 supplies a code mismatch notification R23 to theUI processing section 412. Upon reception of the code mismatch notification R23 from the parentallock processing section 415, theUI processing section 412 performs an error processing so that the fact that an input error of the parental unlock code occurs is indicated for the user through thedisplay section 404. After that, theUI processing section 412 causes themenu screen 801 to be displayed again on thedisplay section 404, thereby urging the user to perform a subsequent operation (Step S124). - The description will be return to the case where the parental lock setting is released. After the process of Step S206, the parental
lock processing section 415 of theremote controller 400 performs the processing as follows. The parentallock processing section 415 transmits, to theclient apparatus 500 by using theoptical communication section 402, a parental lock release notification R24 including the content ID of the content that has been subjected to the release of the parental lock and the apparatus ID of theserver apparatus 600 a in which the data of the content is accumulated (Step S207). - The
list relay section 543 of theclient apparatus 500 receives the parental lock release notification R24 from theremote controller 400 by using the optical communication section 511 (Step S208). Thelist relay section 543 transmits a parental lock release notification C10 including the content ID included in the parental lock release notification R24 to theserver apparatus 600 a corresponding to the apparatus ID included in the received parental lock release notification R24 via the home network 200 (Step S209). - Upon reception of the parental lock release notification C10 from the
client apparatus 500, the parental lock processing section 633 of theserver apparatus 600 a performs the processing as follows. Based on the content ID included in the parental lock release notification C10, the parental lock processing section 633 updates the value of the parental lock flag set to the corresponding content in the content list table 720 from “with parental lock” to “without parental lock” (Step S210). - Next, the parental lock processing section 633 transmits an update completion notification S3 including the apparatus ID and the content ID included in the parental lock release notification R24 to the
client apparatus 500 via the home network 200 (Step S211). - Upon reception of the update completion notification S3 (Step S212), the
list relay section 543 of theclient apparatus 500 transmits an update completion notification C16 including the apparatus ID and the content ID included in the update completion notification S3 to theremote controller 400 by using the optical communication section 511 (Step S213). - The parental
lock processing section 415 of theremote controller 400 receives the update completion notification C16 from the client apparatus 500 (Step S214). - Even in a case where the parental lock settings for the plurality of
server apparatuses 600 are released, by performing the setting release operation of the parental lock as described above, the parental lock settings can be unified and managed by theremote controller 400, with the result that the convenience for the user is improved. - (Reproduction Operation of Content to which Parental Lock is set)
- Next, a reproduction operation of the content to which the parental lock is set will be described with reference to
FIG. 26 .FIG. 26 is a flowchart showing the reproduction operation of the content to which the parental lock is set by thecontent management system 100. - As shown in
FIG. 26 , the operations of Steps S101 to S124 are performed. Let as assume that in Step S124, the execution of a “reproduction” processing is selected by the user by using theinput operation section 405 on themenu screen 801 displayed on the screen of thedisplay section 404 of theremote controller 400. Theinput operation section 405 supplies the selection information R12 of the “reproduction” processing selected by the user to the UI processing section 412 (Step S401). - Upon reception of the selection information R12 of the “reproduction” processing from the
input operation section 405, theUI processing section 412 creates display data of the parental unlock code input screen 802 (shown inFIG. 16 ) based on the selection information R12 and supplies the display request R13 including the display data to thedisplay section 404. As a result, the parental unlockcode input screen 802 is displayed on the screen of thedisplay section 404. - The user references the parental unlock
code input screen 802 displayed on thedisplay section 404 and inputs the parental unlock code by using theinput operation section 405. Theinput operation section 405 supplies the parental unlock code R14 input by the user to theUI processing section 412. - Upon reception of the parental unlock code R14 from the
input operation section 405, theUI processing section 412 causes the input parental unlock code to be displayed for conformation on the parental unlockcode input screen 802 of thedisplay section 404. The user confirms whether the parental unlock code displayed is correct. When the parental unlock code is correct, the user presses a specific key of theinput operation section 405 and inputs the fact that the parental unlock code to be input is decided (Step S402). - The
input operation section 405 notifies theUI processing section 412 of the decision. In response to this notification, theUI processing section 412 supplies, to the parentallock processing section 415, the parental lock release request R15 including the input parental unlock code and the content ID corresponding to the content that the user decides to reproduce in Step S123. Upon reception of the parental lock release request R15, the parentallock processing section 415 reads the parental unlock code registered in the parental unlock code field 734 (see,FIG. 17 ) in the corresponding record from the content management table 730 based on the content ID included in the parental lock release request R15. Then, the parentallock processing section 415 compares the parental unlock code included in the input parental lock release request R15 with the parental unlock code that is read from the parentalunlock code field 734 of the content management table 730 (Step S403). - When it is judged that both the parental unlock codes coincide (Yes in Step S404), the parental
lock processing section 415 performs the following processing. That is, the parentallock processing section 415 transmits, to theclient apparatus 500 by using theoptical communication section 402, a reproduction request R25 including the apparatus ID and the content ID corresponded to the content selected by the user (Step S405). - The
list relay section 543 of theclient apparatus 500 receives the reproduction request R25 from theremote controller 400 by using the optical communication section 511 (Step S406). Thelist relay section 543 transmits a content reproduction request C11 including the content ID included in the reproduction request R25 to theserver apparatus 600 a corresponding to the apparatus ID included in the received reproduction request R25 via the home network 200 (Step S407). - The
reproduction processing section 626 of theserver apparatus 600 a receives the content reproduction request C11 from theclient apparatus 500 via thehome network 200. Upon reception of the content reproduction request C11, thereproduction processing section 626 performs a reproduction processing with respect to the content based on the content ID included in the content reproduction request C11 (Step S408). - On the other hand, in Step S404, if it is judged that the parental unlock codes do not coincide (No in Step S404), the parental
lock processing section 415 supplies the code mismatch notification R23 to theUI processing section 412. Upon reception of the code mismatch notification R23 from the parentallock processing section 415, theUI processing section 412 performs an error processing so that the fact that the input error of the parental unlock code occurs is indicated for the user through thedisplay section 404. After that, theUI processing section 412 causes themenu screen 801 to be displayed again on thedisplay section 404, thereby urging the user to perform a subsequent operation (Step S124). - (Move Operation of Content to which Parental Lock is Set)
- Next, a move operation of the content to which the parental lock is set will be described with reference to
FIG. 22 .FIG. 22 is a flowchart showing the move operation of the content to which the parental lock is set by thecontent management system 100. - As shown in
FIG. 22 , the operations of Steps S101 to S124 are performed. In Step S124, the user selects the execution of a “move” processing by using theinput operation section 405 on themenu screen 801 displayed on the screen of thedisplay section 404 of theremote controller 400. Theinput operation section 405 supplies, to theUI processing section 412, the selection information R12 of the “move” processing selected by the user (Step S301). - Upon reception of the selection information R12 of the “move” processing from the
input operation section 405, theUI processing section 412 creates the display data of the parental unlock code input screen 802 (shown inFIG. 16 ) based on the selection information R12 and supplies the display request R13 including the display data to thedisplay section 404. As a result, the parental unlock code input screen 802 (shown inFIG. 16 ) is displayed on the screen of thedisplay section 404. - The user references the parental unlock
code input screen 802 displayed on thedisplay section 404 and inputs the parental unlock code by using theinput operation section 405. Theinput operation section 405 supplies a parental unlock code R20 input by the user to theUI processing section 412. - Upon reception of the parental unlock code R20 input from the
input operation section 405, theUI processing section 412 causes the input parental unlock code to be displayed for confirmation on the parental unlockcode input screen 802 of thedisplay section 404. The user confirms whether the parental unlock code displayed is correct. When the parental unlock code is correct, the user presses a specific key of theinput operation section 405 and inputs the fact that the parental unlock code to be input is decided (Step S302). - The
input operation section 405 notifies theUI processing section 412 of the decision. In response to this notification, theUI processing section 412 supplies, to the parentallock processing section 415, a move authorization request R31 including the input parental unlock code and the content ID corresponding to the content that the user has decided to move in Step S123. Upon reception of the move authorization request R31, the parentallock processing section 415 reads the parental unlock code registered in the parental unlock code field 734 (shown inFIG. 17 ) in the corresponding record from the content management table 730 based on the content ID included in the move authorization request R31. Then, the parentallock processing section 415 compares the parental unlock code included in the move authorization request R31 with the parental unlock code read from the parentalunlock code field 734 of the content management table 730 (Step S303). - In Step S304, if it is judged that the parental unlock codes do not coincide (No in Step S304), the parental
lock processing section 415 supplies the code mismatch notification R23 to theUI processing section 412. Upon reception of the code mismatch notification R23 from the parentallock processing section 415, theUI processing section 412 performs an error processing so that the fact that an input error of the parental unlock code occurs is indicated for the user through thedisplay section 404. After that, theUI processing section 412 causes themenu screen 801 to be displayed again on thedisplay section 404, thereby urging the user to perform a subsequent operation (Step S124). - When it is judged that both the parental unlock codes coincide (Yes in Step S304), the parental
lock processing section 415 performs the operation as follows. The parentallock processing section 415 gives an instruction to theUI processing section 412 to perform a processing so that the user selects one from among theserver apparatuses 600 as a move destination. - Upon reception of the instruction from the parental
lock processing section 415, theUI processing section 412 reads theserver name 702 from the server list table 710, creates display data of the server selection screen 800 (shown inFIG. 11 ) including the list of theserver names 702, and supplies the display request R4 including the display data to thedisplay section 404. The user references theserver selection screen 800 and selects theserver apparatus 600 as the move destination of the content by using theinput operation section 405. Herein, let as assume that theserver apparatus 600 b is selected (Step S305). - The
input operation section 405 supplies, to theUI processing section 412, the move destination notification R28 including the apparatus ID of theserver apparatus 600 b selected as the move destination by the user. Upon reception of the move destination notification R28, theUI processing section 412 supplies, to themove processing section 416, the apparatus ID of theserver apparatus 600 b as the move destination, which is included in the move destination notification R28. Further, theUI processing section 412 supplies, to themove processing section 416, the content ID included in the selection information R10 received in Step S123 and the apparatus ID of theserver apparatus 600 a as a move source, which is included in the server selection request R5 received in Step S112. - Upon reception of those information items from the
UI processing section 412, themove processing section 416 transmits the move request R29 including those information items to theclient apparatus 500 by using the optical communication section 402 (Step S306). - The
list relay section 543 of theclient apparatus 500 receives the move request R29 from theremote controller 400 by using the optical communication section 511 (Step S307). Based on the apparatus ID of the server apparatus as the move source included in the move request R29, thelist relay section 543 transmits, to the correspondingserver apparatus 600 a, the move request C12 including the apparatus ID of theserver apparatus 600 b as the move destination and the content ID included in the move request R29 (Step S308). - The
move processing section 634 of theserver apparatus 600 a as the move source receives the move request C12 from theclient apparatus 500 via thehome network 200. Themove processing section 634 reads data of the content corresponding to the content ID included in the move request C12 from the contentdata storage section 624. Subsequently, themove processing section 634 transmits the read content data to the correspondingserver apparatus 600 b via thehome network 200 based on the apparatus ID of the server apparatus as the move destination, which is included in the move request C12 (Step S309). - Upon completion of the transmission of the content data, the
move processing section 634 deletes the content data from the content data storage section 624 (Step S310). Themove processing section 634 supplies a record deletion request to the contentlist processing section 631 of the apparatus to which themove processing section 634 itself belongs. Upon reception of the record deletion request, the contentlist processing section 631 deletes the information (record) as to the content moved in Step S310 from the content list table 720 stored in the content list storage section 632 (Step S311). - On the other hand, the
server apparatus 600 b as the move destination performs the following processing. That is, themove processing section 634 of theserver apparatus 600 b receives, via thehome network 200, data of the content transmitted in Step S310 from theserver apparatus 600 a as the move source (Step S312). Themove processing section 634 writes the data of the content received in the contentdata storage section 624 thereof (Step S313). Further, themove processing section 634 registers as a new record, in the content list table 720 thereof, the content ID, the program title, and the value of the parental lock flag that are the information on the currently received content (Step S314). - The description will be returned to the operation of the
server apparatus 600 a as the move source. Upon completion of the move as described above, the contentlist processing section 631 of theserver apparatus 600 a as the move source performs the following processing. The contentlist processing section 631 transmits, to theclient apparatus 500 via thehome network 200, a move completion notification S4 including the information on the content that have been moved, the apparatus ID thereof as the move source, and the apparatus ID of the apparatus as the move destination (Step S315). - Upon reception of the move completion notification S4 from the
server apparatus 600 a via the home network 200 (Step S316), thelist relay section 543 of theclient apparatus 500 transmits a move completion notification C13 to theremote controller 400 by using the optical communication section 511 (Step S317). The move completion notification C13 includes the information on the content, the apparatus ID thereof as the move source, and the apparatus ID of the apparatus as the move destination. - The parental
lock processing section 415 of theremote controller 400 receives the move completion notification C13 from the client apparatus 500 (Step S318). Upon reception of the move completion notification C13, the parentallock processing section 415 updates the content management table 730 stored in the contentlist storage section 414 based on the information included in the move completion notification C13 (Step S319). That is, the parentallock processing section 415 deletes the information (record) as to the already moved content of theserver apparatus 600 a as the move source from the content management table 730 stored in the contentlist storage section 414. In addition, the parentallock processing section 415 adds the information (record) as to the already moved content of theserver apparatus 600 b as the move destination to the content management table 730.FIG. 23 is a diagram showing an example of the update of the content management table 730 because of the move. In this example, described is a case where data of a content whose content ID is “Program 2” stored in a server apparatus whose apparatus ID is “Server 2” is moved to a server apparatus whose apparatus ID is “Server 1”. In the case of the move, when the parental unlock code is included in the record of the information on the content as the move source, the parentallock processing section 415 performs the following processing before the information on the content as the move source is deleted. That is, the parentallock processing section 415 moves the parental unlock code to the record of the information on the content as the move destination on the content management table 730. - When the content management table 730 is updated, the parental
lock processing section 415 supplies an update completion response R27 of the content management table 730 to theUI processing section 412. Upon reception of the update completion response R27, theUI processing section 412 creates display data of adialog screen 803 for causing the user to determine whether the parental lock is set with respect to the moved content as shown inFIG. 25 , for example. Then, theUI processing section 412 supplies the display request R4 including the display data of the createddialog screen 803 to thedisplay section 404. - Based on the display request R4 supplied from the
UI processing section 412, thedisplay section 404 displays thedialog screen 803 on the display screen thereof (Step S320). The user references thedialog screen 803 displayed on thedisplay section 404 and determines whether the parental lock is set or not by using theinput operation section 405. Herein, if the user performs the input operation so that the parental lock is set by using the input operation section 405 (Yes in Step S321), the process of the flowchart is terminated with the parental lock being set with respect to the content moved to theserver apparatus 600 b. - On the other hand, if the user performs the input operation so that the parental lock is not set by using the input operation section 405 (No in Step S321), the
UI processing section 412 supplies a parental lock release request R30 to the parentallock processing section 415. Upon reception of the parental lock release request R30, the parentallock processing section 415 updates the content management table 730 stored in the content list storage section 414 (Step S322). That is, as shown inFIG. 24 , the parentallock processing section 415 updates the value of the parental lock flag corresponding to the already moved content of theserver apparatus 600 b as the move destination, which is added to the content management table 730 in Step S319, from “with parental lock” to “without parental lock”, for example. Further, the parentallock processing section 415 deletes the parental lock management code that is associated with the content and registered in the content management table 730. - Upon completion of the update of the content management table 730, the parental
lock processing section 415 performs the following processing. That is, the parentallock processing section 415 transmits a parental lock release notification R32 including the content ID of the content and the apparatus ID of theserver apparatus 600 b as the move destination to theclient apparatus 500 by using the optical communication section 402 (Step S323). - The
list relay section 543 of theclient apparatus 500 receives the parental lock release notification R32 including the set of the content ID of the content that is desired to be subjected to the release of the parental lock and the apparatus ID of theserver apparatus 600 b from theremote controller 400 by using the optical communication section 511 (Step S324). Upon reception of the parental lock release notification R32, thelist relay section 543 transmits a parental lock release request C14 including the content ID included in the parental lock release notification R32 to theserver apparatus 600 b corresponding to the apparatus ID included in the parental lock release notification R32 (Step S325). - The parental lock processing section 633 of the
server apparatus 600 b receives the parental lock release request C14 from theclient apparatus 500 via the home network 200 (Step S326). Upon reception of the parental lock release request C14, the parental lock processing section 633 of theserver apparatus 600 b updates the content list table 720 stored in the contentlist storage section 632 thereof based on the parental lock release request C14 (Step S327). That is, based on the content ID included in the parental lock release request C14, the parental lock processing section 633 retrieves the corresponding record on the content list table 720 and updates the value of the parental lock flag in the record from “with parental lock” to “without parental lock”. - Upon completion of the update of the content list table 720, the parental lock processing section 633 of the
server apparatus 600 b transmits a parental lock release completion notification S5 to theclient apparatus 500 via the home network 200 (Step S328). - The
list relay section 543 of theclient apparatus 500 receives the parental lock release completion notification S5 from theserver apparatus 600 b via the home network 200 (Step S329). Upon reception of the parental lock release completion notification S5, thelist relay section 543 transmits a parental lock release completion notification C15 to theremote controller 400 by using the optical communication section 511 (Step S330). - The parental
lock processing section 415 of theremote controller 400 receives the parental lock release completion notification C15 from theclient apparatus 500 by using the optical communication section 402 (Step S331). In this way, the parental lock is set with respect to the content that has been moved. - With the parental lock setting operation described above, even in a case where the minor wants to move the content with his/her
own server apparatus 600, the move operation without the use of theremote controller 400 is not allowed. As a result, the parent or guardian can remotely set the parental lock by using theremote controller 400, which improves the convenience for the user. - The embodiment of the present invention is not limited to the above embodiment and can be variously modified without departing from the gist of the present invention.
