Corresponds to the division.

  Based on the configuration as described above, the present invention will be described in more detail.

  In the receiving apparatus 100, when the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) are operating at the same time, functions belonging to the Cable service domain 404 may be executed simultaneously for each application. Therefore, in the present invention, data sharing is performed between the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) regarding functions belonging to the receiver domain 402. Hereinafter, data sharing between the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) will be described in detail. In the following description, as an example of data sharing, a case of caption information (closed caption) for a hearing-impaired person included in an input video signal will be described. Note that the present invention is not limited to subtitle information, and any other setting information for setting video / audio output may be used.

  Hereinafter, the data sharing process during the operation of the OCAP application (52a, 52b) will be described with reference to FIG. First, the state of the receiving apparatus 100 at the start of the data sharing process during the operation of the OCAP application (52a, 52b) in FIG. 5 will be described.

  At the start point (S100) of the data sharing process during the operation of the OCAP application (52a, 52b) in FIG. 5, in the state transition diagram of the receiving apparatus 100 shown in FIG. Then, after the transition to the legacy service state 304 via the NoCard state 303 depending on whether or not the cable card 300 is inserted, XAIT is received in the legacy service state 304, and the OCAP Service state 305 is entered.

  In the functional configuration diagram of the receiving apparatus 100 shown in FIG. 2, in the built-in applications (51a, 52a), for example, a channel selection application for channel selection is operating, and the OCAP applications (52a, 52b) ), For example, a channel selection application for channel selection is in operation. These built-in applications (51a, 52a) are activated by the built-in application management unit 53, and the OCAP applications (52a, 52b) are activated by the OCAP application management unit 54 to manage their operations. .

  In the operation mode management unit 55, the operation mode is set from the IDTV mode to the OCAP mode, and the built-in application status is “channel selection application in operation” and the OCAP application status is “channel selection application in operation”. Information is stored. Further, the data management unit 58 stores setting information that is currently set. For example, information indicating that the current closed caption setting is OFF is stored. In the above description, the operation mode management unit 55 determines the status of the channel selection application, but this does not specifically acquire the status of the OCAP application, and one application is running. It is also possible to acquire the state that the OCAP application is operating as the channel selection application by determining the application as the channel selection application.

  In such a situation, referring to the hardware configuration diagram of the receiving device 100 in FIG. 1, the functional configuration diagram of the receiving device 100 in FIG. 2, and the flowcharts in FIGS. 5 and 6, the built-in application ( 51a, 51b) and data sharing information sharing processing between the OCAP applications (52a, 52b) will be described.

  The receiving apparatus 100 determines whether or not a key input (event input) related to the change of the setting information is input from the remote control 400 via the remote control receiving unit 18 (S102). Here, the key input relating to the change of the setting information is a signal for requesting activation of the setting application. Specifically, it is determined whether or not a key input input from remote control 400 is input to remote control reception unit 18.

  Next, when it is determined in S102 that a key input has been input, the receiving apparatus 100 acquires the current mode information from the operation mode management unit 55, and the currently operating application management unit activates the setting application ( S104). More specifically, since the current operation mode is the OCAP mode in the operation mode management unit 55 as described above, the key input relating to the change of the setting information is performed via the key distribution unit 56 through the OCAP application management unit. 54 is notified. In response to this notification, the OCAP application management unit 54 activates a setting application that is one of the OCAP applications (52a, 52b), and notifies the operation mode management unit 55 of this operation state. Accordingly, at this time, the operation mode of the operation mode management unit 55 indicates “OCAP application”, and the OCAP application is operating the “channel selection application and setting application”, and the built-in application is “channel selection”. Application "is running.

  In the above description, the operation mode in the operation mode management unit 55 is determined, and the key input is distributed from the key distribution unit 56 to either the built-in application management unit 53 or the OCAP application management unit 54. In the present invention, as another realization means, the remote controller 400 determines in advance whether the key input is to be transmitted to the built-in application management unit 53 or the OCAP application management unit 54, and receives the key input. The configuration may be such that the key input is delivered to either the built-in application management unit 53 or the OCAP application management unit 54 previously selected by the remote controller 400. In this case, when the user performs key input on the remote controller 400 in advance, it is possible to select whether the key input is for the built-in application management unit 53 or the OCAP application management unit 54.

  Next, it is determined whether or not an input regarding the setting information has been made (S106). Specifically, the setting application reads the closed caption setting information stored in the data management unit, outputs it on the screen, and the user changes the content output on this screen with the remote control 400, and the decision is made. By determining whether or not the setting has been made, it is determined whether or not the closed caption setting has been changed. For example, as described above, when the closed caption = OFF state is set in the current data management unit 58 and the closed caption = ON state is selected by the current key input, the input regarding the setting information is performed. It is determined that has been made.

  Here, when an input related to the setting information is made in S106, the contents set in the setting application are stored in the closed caption area to which the built-in application management unit 53 and the OCAP application management unit 54 refer together in the data management unit 58. Set.

  When the above processing is completed, the setting application is terminated. Along with the end of the setting application, the user can view the video signal displayed by the channel selection application in the above-described closed caption = ON state.

  Next, data sharing in the built-in application management unit 53 will be described with reference to the flowchart in FIG. Here, in the above state, it is assumed that the OCAP Service state in FIG. 3 is changed to the Legacy Service state.

  In the operation mode management unit 55, the operation mode is set from the OCAP mode to the IDTV mode, and the built-in application state is “in operation of the channel selection application” and the OCAP application state is “in operation of the channel selection application”. Information is stored. Further, the data management unit 58 stores setting information that is currently set. For example, information indicating that the current closed caption setting is ON is stored.

  First, the receiving apparatus 100 determines whether or not the application has been changed to a built-in application (51a, 51b) (S202). Specifically, the operation mode management unit 55 determines whether or not the operation mode is set from the OCAP mode to the IDTV mode.

  Next, when it is determined that the built-in application (51a, 51b) is set, the built-in application management unit 53 activates a caption setting application which is one of the built-in applications. With this caption setting application, the closed caption setting information set in the data management unit 58 by the setting application described above is set (S206). Specifically, the caption setting application acquires information that the closed caption setting of the data management unit 58 is turned ON by the channel selection application, and turns ON the closed caption setting in the built-in applications (51a, 51b). To do.

  When the above process is completed, the caption setting application is terminated. Upon completion of the caption setting application, the user can view the video signal displayed by the channel selection application in the above-described closed caption = ON state.

  As a result, the user can take over the closed caption setting once set using the setting application which is one of the OCAP applications (52a, 52b) to the subtitle setting application which is one of the built-in applications (51a, 51b). Thus, it is not necessary for the user to set the closed caption repeatedly, and the user's complexity can be avoided.

  In the above-described state, the case where the operation mode is changed from the OCAP mode to the IDTV mode is described. However, the present invention is not limited to this, for example, as shown in FIG. Even when the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) are activated at the same time, data can be shared in the same manner. Specifically, in FIG. 7, the setting application 702 of the OCAP application (52a, 52b) and the caption setting application 704 of the above-described built-in application (51a, 51b) are simultaneously operating on the TV screen 700. In such a state, the content set by the setting application 702 described above can be shared by the caption setting application 704. In this case, it can be realized by the duplication function management unit 57 notifying the subtitle setting application 704 of the built-in application (51a, 51b) that the data of the data management unit 58 has been changed.

  In the above-described embodiment, the case where both the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) are operating has been described. However, the present invention is not limited to this, For example, even when only the built-in applications (51a, 51b) are activated and the setting information is changed via the caption setting application 704, the OCAP application (52a, 52b) is activated later. It is possible to share data.

  In the above-described embodiment, the example in which the setting information set by the OCAP application (52a, 52b) is reflected in the built-in application (51a, 51b) has been described. However, the present invention is not limited to this. For example, the setting information set by the built-in applications (51a, 51b) can be reflected in the OCAP application (52a, 52b).

(Embodiment 2)
In the first embodiment, by sharing the setting information change (data sharing) between the built-in application (51a, 51b) and the OCAP application (52a, 52b), the user changes the setting information redundantly. Although it has been described that the necessity is eliminated, in all cases, there may be a problem when data is shared between the built-in applications (51a, 51b) and the OCAP applications (52a, 52b).

  For example, when a parental function that is set so that a program inappropriate for young people cannot be viewed is set in the built-in application (51a, 51b) or the OCAP application (52a, 52b), respectively. When the parental function of only one of the application (51a, 51b) or OCAP application (52a, 52b) is reset, the parental function of the other application is also reset by sharing the reset data. If this happens, the application that is not intended by the user is also reset, and the program that is not appropriate for young people can be viewed.

  Therefore, in the present invention, the data management unit 58 has a first area for storing setting information shared by the built-in applications (51a, 51b) and the OCAP applications (52a, 52b), the built-in applications (51a, 51b), and The OCAP application (52a, 52b) has a second area for storing setting information for independently accessing different setting information, and a key input for setting the setting information of the currently running application to the initial state is made In this case, all or part of the first area that stores the setting information that the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) commonly access among the setting information stored in the data management unit 58. And the built-in application (51a, 5 b) and OCAP applications (52a, 52b) to reset the whole or part of the setting information of the application currently running in the second region for storing setting information for accessing independently different configuration information.

  Thus, the present invention eliminates the need to reset each of the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) even when the setting information is changed to the initial state. The setting information that cannot be reset can be reset for each built-in application (51a, 51b) or OCAP application (52a, 52b).

  Hereinafter, as an example, the processing when the user performs key input (reset) for setting the setting information to the initial state via the remote controller 400 for the setting information stored in the data management unit 58 will be described in detail. To do.

  In the second embodiment, the closed caption set by the user via the remote controller 400 in the first embodiment will be described as an example. However, the present invention is not limited to this, and other video / Any setting information for setting the output of the sound may be used. Hereinafter, the change of the setting information of the present invention to the initial state will be described with reference to FIG. FIG. 8 explains the processing after S106 in FIG. Here, it is assumed that a reset key input is performed by the user via the remote controller 400 in S106 of FIG.

  The receiving apparatus 100 determines whether or not a key input (reset) related to reset is input from the remote controller 400 via the remote controller receiver 18 (S802). Here, the key input relating to reset is a signal for requesting activation of an application for changing the setting information of the currently activated application to an initial state. Further, even when the application is not activated, a signal requesting change of setting information in the setting application may be used.

  Next, if it is determined in S802 that a key input relating to reset has been made, the receiving apparatus 100 acquires current mode information from the operation mode management unit, and the currently operating application management unit activates the setting application ( S804). More specifically, since the current operation mode is the OCAP mode in the operation mode management unit 55 as described above, the key input relating to the change of the setting information is performed via the key distribution unit 56 through the OCAP application management unit. 54 is notified.

  In response to this notification, as shown in FIG. 9, the OCAP application management unit 54 activates a setting application (902 in FIG. 9) which is one of the OCAP applications (52a, 52b), and changes the operation state to the operation mode. The management unit 55 is notified. Accordingly, at this time, the operation mode of the operation mode management unit 55 indicates “OCAP application”, and the OCAP application (52a, 52b) is operating the “channel selection application and setting application”, and the built-in application In (51a, 51b), the “channel selection application” is being activated.

  In the second embodiment, the setting application, which is one of the OCAP applications, is activated in response to the reset key input. However, the present invention is not limited to this, and as shown in FIG. In addition, as one of the OCAP applications, it is also possible to start a reset application (1002 in FIG. 10) dedicated to resetting.

  In the above description, a configuration is described in which the operation mode in the operation mode management unit 55 is determined, and the reset key input is delivered from the key delivery unit 56 to either the built-in application management unit 53 or the OCAP application management unit 54. However, in the present invention, as another realization means, the remote controller 400 determines in advance which of the built-in application management unit 53 or the OCAP application management unit 54 should transmit the reset key input, and receives the key input. The key delivery unit 56 may deliver the key input to either the built-in application management unit 53 or the OCAP application management unit 54 selected in advance on the remote controller 400. In this case, when the user performs key input on the remote controller 400 in advance, it is possible to select whether the key input is for the built-in application management unit 53 or the OCAP application management unit 54.

  Next, it is determined whether or not a key input for resetting the setting information has been made (S806). Specifically, as a first method, as shown in FIG. 9, the setting application 902 is output on the screen, and it is determined whether or not the user has decided to reset with the remote control 400, thereby setting information It is determined whether or not a reset key input has been made. As a second method, as shown in FIG. 10, a reset application 1002 is output on the screen, and it is determined whether or not the user has decided to reset with the remote control 400, thereby resetting the setting information. It is determined whether or not a key input has been made.

  Next, in step S806, when a reset key is input, the OCAP application notifies the data management unit 58 of the initial value setting via the OCAP application management unit, thereby the data management unit 58. A first area for storing setting information that is commonly accessed by both the built-in applications (51a, 51b) and the OCAP application (52a, 52b) and a second area for storing setting information that each application accesses separately The setting information is changed (S808, S810).

  Here, the first area refers to an area 1102 shown in FIG. If the contents described in this area are reset by either the built-in application (51a, 51b) or the OCAP application (52a, 52b), the setting information of the data management unit 58 is set to the initial state. Set. Therefore, in the above-described example, as described in the first embodiment, since the closed caption setting is in the OFF state in the initial state, the ON state is changed to the OFF state.

  The second area refers to the area 1104 shown in FIG. The contents described in this area are only the setting information of the corresponding application when a reset key input is made by either the built-in application (51a, 51b) or the OCAP application (52a, 52b). Is the area where is set to the initial state. Therefore, in the above-described example, only the setting information described in the address 1001 related to the currently operating OCAP application (52a, 52b) is changed among the parental controls described in FIG. The setting information described at the address 1010 which is the parental control is setting information related to the built-in applications (51a, 51b), and is not reset.

  With the configuration as described above, in the receiving device 100 of the present invention, by changing the setting information (data sharing) between the built-in applications (51a, 51b) and the OCAP applications (52a, 52b), the user can Therefore, it is not necessary to change the setting information in duplicate, and by preventing unnecessary data sharing, it is possible to eliminate a user's trouble caused by data sharing.

  In the second embodiment, the case of reset has been described. However, the present invention is not limited to this, and the same processing can be performed for other user key inputs. is there.

  It is also possible for the user to select in advance whether the setting information is stored in the first area or the second area for each content of the setting information. This makes it possible to share data according to user preferences.

  Further, as shown in FIG. 7, even when the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) are activated at the same time, the data reset process can be performed in the same manner. Specifically, in FIG. 7, the setting application 702 of the OCAP application (52a, 52b) and the caption setting application 704 of the above-described built-in application (51a, 51b) are simultaneously operating on the TV screen 700. In such a state, the contents set by the setting application 702 can be reflected in the caption setting application 704. In this case, this can be realized by the overlapping function management unit 57 notifying the subtitle setting application 704 of the built-in applications (51a, 51b) that the setting information of the first area of the data management unit 58 has been changed. Is possible.

  In the above-described embodiment, the example in which the reset key input set by the OCAP application (52a, 52b) is reflected in the built-in application (51a, 51b) has been described. However, the present invention is limited to this. Instead, for example, the reset key input set by the built-in applications (51a, 51b) can be reflected in the OCAP applications (52a, 52b).

(Embodiment 3)
In the first embodiment, the setting information set by either the built-in application (51a, 51b) or the OCAP application (52a, 52b) is set between the built-in application (51a, 51b) and the OCAP application (52a, 52b). In the third embodiment, it has been described that the user does not need to change the setting information repeatedly by sharing the change of the setting information (data sharing) between the built-in applications (51a, 51b). ) Or an OCAP application (52a, 52b), and an example in which arbitration is performed between the built-in application (51a, 51b) and the OCAP application (52a, 52b) in response to a key input set by one of the OCAP applications (52a, 52b). . In the third embodiment, the TimerOn function will be described as an example. The TimerOn function is to start channel selection of a predetermined service at a predetermined time even if the user is currently viewing the service, and automatically change the service currently being viewed by the user to the newly selected service. The function to be changed. In this embodiment, the TimerOn function will be described, but the present invention is not limited to this. Hereinafter, processing of the TimerOn function will be described with reference to FIG. Here, FIG. 12 shows a flowchart of processing for arbitrating the TimerOn function.

  In the state transition diagram of the receiving apparatus 100 shown in FIG. 3, after the AC power is turned on in the main power off state 301, the insertion of the cable card 300 is performed at the start time (S1200) of the arbitration process during the OCAP operation in FIG. After transitioning to the legacy service state 304 via the NoCard state 303 depending on the presence or absence, XAIT is received in the legacy service state 304 and the OCAP Service state 305 is entered.

  In the functional configuration diagram of the receiving apparatus 100 shown in FIG. 2, in the built-in applications (51a, 52a), for example, a channel selection application for channel selection is operating, and the OCAP applications (52a, 52b) ), For example, a channel selection application for channel selection is in operation. These built-in applications (51a, 52a) are activated by the built-in application management unit 53, and the OCAP applications (52a, 52b) are activated by the OCAP application management unit 54 to manage their operations. .

  In the operation mode management unit 55, the operation mode is set from the IDTV mode to the OCAP mode, and the built-in application status is “channel selection application in operation” and the OCAP application status is “channel selection application in operation”. Information is stored. Further, the duplication function management unit 57 stores channel selection information that the built-in applications (51a, 51b) have made key input for starting channel selection for a predetermined service at a predetermined time. Note that the process of storing the channel selection information in the duplicate function management unit 57 is a process that has been generally performed, and thus the description thereof is omitted.

  In such a situation, referring to the hardware configuration diagram of the receiving device in FIG. 1, the functional configuration diagram of the receiving device in FIG. 2, and the flowchart in FIG. 12, the built-in applications (51a, 51b) and the OCAP applications (52a, 52b) ) Will be described.

  The receiving apparatus 100 compares the time information of the channel selection information stored in the duplicate function management unit 57 with the time information that is not shown, but is held by the timer of the receiving apparatus 100, and whether or not they match. Is determined (S1202). Specifically, for example, when channel selection information for selecting 6ch is stored at 9 pm, it is determined whether it is 9 pm as compared with the current time of the timer of the receiving device 100. .

  Next, if the receiving apparatus 100 determines in S1202 that the times match, the receiving apparatus 100 performs an arbitration process between the service currently being viewed and the service selected by the channel selection information. Specifically, although the OCAP application (52a, 52b) is currently operating, the built-in application (51a, 51b) interrupts via the built-in application management unit 53, and the duplicate function management unit 57 receives the OCAP application ( 52 a and 52 b) and the service selected by the built-in application (51 a and 51 b) based on the channel selection information are arbitrated for output on the screen.

  As a standard for this arbitration, the data management unit 58 is provided with information on the priorities of the built-in applications (51a, 51b) and the OCAP applications (52a, 52b), and the duplicate function management unit 57 performs arbitration. When performing, it is also possible to perform arbitration based on the priority order stored in the data management unit 58.

  In addition, as another reference for performing arbitration, the operation mode of the built-in applications (51a, 51b) and the OCAP application (52a, 52b) (for example, the OCAP application is in a VOD (Video On Demand) state) is used. It is also possible to perform arbitration based on the operation state acquired from the management unit 55.

  Next, in S1204, the receiving apparatus 100 notifies the operation mode management unit 55 of the arbitration result as to whether the built-in application (51a, 51b) or the OCAP application (52a, 52b) is selected by the duplicate function management unit 57. . Receiving this arbitration result, receiving apparatus 100 determines whether or not to change the channel selection (S1206).

  When it is determined that the channel selection is to be changed, that is, in the above-described example, the mode is changed from the OCAP application (52a, 52b) to the built-in application (51a, 51b) and set by the built-in application (51a, 51b). Based on the channel selection information, channel 6 is selected at 9pm. In this case, the duplicate function management unit 57 notifies the OCAP application (52a, 52b) via the OCAP application management unit that the channel selection has been changed to 6ch.

  On the other hand, when it is determined that the channel selection is not changed, that is, in the above-described example, when it is determined that the operation mode is not changed from the OCAP application (52a, 52b) to the built-in application (51a, 51b), The channel selection by the OCAP application (52a, 52b) is continuously performed.

  With the configuration as described above, in the present invention, even if duplicate operations are performed by the built-in applications (51a, 51b) and the OCAP applications (52a, 52b), one of the applications is selected. Thus, resource control between the OCAP application and the built-in application can affect each other and prevent malfunctions.

  In the above-described embodiment, an example in which arbitration between the built-in application (51a, 51b) and the OCAP application (52a, 52b) is described based on the channel selection information set by the built-in application (51a, 51b) has been described. However, the present invention is not limited to this, and can be reflected in the built-in applications (51a, 51b) based on the channel selection information set by the OCAP applications (52a, 52b), for example.

  The present invention can be used for a receiving apparatus that performs parallel processing on an OCAP application received from a broadcasting station and a built-in application stored in advance in the receiving apparatus.
