Description

Digital broadcast receiver and digital broadcast receiving method

The present invention relates to an apparatus and method for receiving a digital broadcast, and in particular, a digital broadcast receiver capable of executing an application (for example, an application conforming to the DVB-MHP standard (hereinafter referred to as “MHP application”)) and The present invention relates to a method for receiving a digital broadcast in the digital broadcast receiver.

In digital broadcasting, data of a plurality of services are multiplexed to form a data stream, which is transmitted from a broadcasting station as MPEG-2 TS (Transport Stream). The digital broadcast receiver (hereinafter sometimes abbreviated as “receiver”) that has received the TS can identify the different services for the plurality of encoded signals constituting the multiplexed service. Includes information such as PSI (Program Specific Information) and SI (Program Information (Service Information)). The PSI includes a PMT (program correspondence table (Program MapＭＴTable)). The PMT includes information for specifying the PID (packet identifier (Packet 各種 Identifier)) of each encoded signal of various data constituting the service. PID of AIT (Application Information Table) to be described later is described. The receiver refers to the PID of the PMT and identifies a data packet containing the necessary data, thereby extracting necessary data from the TS while recognizing the different service. In the present application, the term “service” is synonymous with “program” distinguished by the PMT.

Now, one of the standards defining the specifications of digital broadcasting is the DVB-MHP (Digital Video Broadcasting-Multimedia Home Platform) standard. The DVB-MHP standard is a middleware for causing a receiver to execute an application (MHP application; hereinafter, abbreviated as “MHP application”) that is sent to the receiver via a digital broadcast wave or the like. It is a standard. The MHP application is sent to the receiver in an object carousel method using, for example, a section of the TS. The received MHP application is executed by a Java (registered trademark) virtual machine (Java VM) (included in the middleware) running on the operating system (OS) of the digital broadcast receiver.

The MHP application includes an EPG (Electronic Program Guide) application that provides a function for a user to select a service (program), a game application that provides a game, and a weather forecast application that provides weather forecast information. Software that provides various functions is included. In addition, the EPG application can display, for example, a service title at the time of service selection (channel selection),
・ Browsing of electronic program guides ・ Displaying the contents of each service ・ Searching for services by genre or title, based on information input by the user via the user interface of the receiver, This is an application having a function (channel selection function) for switching a service to be provided.

The receiver has a function of automatically starting and stopping an MHP application based on (MHP) application control information (AIT) sent from a broadcasting station without bothering the viewer. The AIT (Application Information Table) is data including additional application information for specifying and controlling the MHP application. The receiver detects the PID of the AIT from the PMT, acquires the AIT, and uses the control information (AUTOSTART, PRESENT, KILL, DESTROY, etc.) included in the AIT to operate all the MHP applications (startup, execution) The automatic control function is realized by determining the life cycle for each MHP application. With this function, the MHP application can be automatically started or stopped by the receiver based on the AIT (Non-Patent Document 1 (Multimedia Home Platform (MHP) Specification 1.1.3)).

An MHP application generally has bidirectionality (interactivity) that can operate in response to user input. In order to realize this bidirectionality, the MHP application may use a part of the input device of the receiver (for example, a specific operation key of the remote controller of the receiver) for inputting information from the user to the MHP application. is there. In that case, during the execution of the MHP application, the input from a specific operation key of the remote controller is exclusively used for the input to the MHP application, and the function originally possessed by the operation key (when the MHP application is not executed) The assigned function) is temporarily lost.

Incidentally, services provided by digital broadcasting include data broadcasting, and data broadcasting includes, for example, text multiplex broadcasting (teletext). In teletext, the viewer often uses the operation keys of the remote controller to select information.

When the viewer is watching teletext (text multiplex broadcasting) and the receiver automatically activates the MHP application based on the detected AIT, the activated MHP application occupies a part of the operation keys. . When there are operation keys partially overlapping between the operation key group occupied by the MHP application and the operation key group used for teletext operation, the viewer can operate the teletext. Unfavorable situations arise, such as disappearance or severely restricted operations.

Therefore, there may naturally be a case where the viewer does not want the MHP application to be automatically activated by the receiver based on the AIT. Therefore, the receiver has two types, an operation control mode (AutoStart_ON) that automatically controls the operation state of the MHP application based on the detected AIT, and an operation control mode (AutoStart_OFF) that does not automatically control the MHP application. The MHP application operation control mode is provided.

When the operation control mode of the AutoStart_ON is set for the receiver, when the receiver detects that an AIT exists in the selected (tuned) service, the operation of the MHP application is performed based on the AIT. Automatically controls state (start, stop, etc.) and life cycle.
On the other hand, when the above-described AutoStart_OFF operation control mode is set for the receiver, the receiver determines whether the operation state of the MHP application or the like regardless of whether or not the AIT related to the selected service is detected. Does not perform automatic control. In this case, in order to execute the activation of the MHP application or the like, the viewer needs to manually control the operation state of the MHP application.

Non-Patent Document 2 (DGTVi operation manual) describes that a receiver has an operation control mode of AutoStart_ON and an operation control mode of AutoStart_OFF, and the viewer can use the two types of operation control modes. Can be set in the receiver so as to be switchable, and in the operation control mode of AutoStart_OFF, the viewer can acquire (start up) the MHP application from the application list.

For example, in Italy, a receiver user (viewer) manually selects an MHP application from an application list that displays a list of MHP applications and issues an execution instruction when the receiver operates in an operation control mode of AutoStart_OFF. The MHP application is activated at the receiver only after input.

In the operation control mode of AutoStart_OFF, the viewer needs to appropriately select an application to be executed from among a plurality of applications displayed in the application list. However, in the application list, an MHP application that operates properly only after being started from another MHP application is also displayed. As a result, viewers sometimes find it difficult to select MHP applications.

As described above, the conventional digital broadcast receiver automatically determines the operating state of an application (for example, MHP application) that is also included in the broadcast wave based on information (for example, AIT) that the broadcast station includes and transmits in the broadcast wave. Some receivers can be configured to control or not.

However, in the conventional digital broadcast receiver, the operation control mode of AutoStart_ON and the operation control mode of AutoStart_OFF are set in the receiver. That is, once the setting is made in the receiver, the setting is applied to all services.
Therefore, if the operation control mode (AutoStart_ON / AutoStart_OFF) currently set for the receiver is different from the desired operation control mode in the service that is desired to be displayed, the viewer can display the service, etc. Before giving instructions to the receiver, the viewer needs to manually switch the setting of the operation control mode.

If the viewer instructs the receiver to display the desired service without changing the operation control mode (AutoStart_ON / AutoStart_OFF) to the desired operation control mode, the MHP application that does not want to start automatically Or, conversely, an MHP application that is desired to be automatically started does not start. As described above, the former case includes a possibility that an operation that restricts operations for data broadcasting or the like may occur. In the latter case, an MHP application that a viewer manually starts from an application list is selected. In doing so, there is a possibility that the viewer may feel the difficulty of selection.

In view of the above-mentioned problems of the prior art, the present invention is configured to enable / disable an automatic control function such as an operating state of an application (for example, an MHP application) based on information included in a broadcast wave such as AIT, a life cycle, Provided are a digital broadcast receiver that can be appropriately switched according to a service to be received, and a digital broadcast receiving method in the digital broadcast receiver.

It is preferable to execute the control of the operation state so as to continue.

Hereinafter, embodiments will be described in detail.

<First Embodiment>
The first embodiment is a digital broadcast receiver (and a digital broadcast receiving method in the receiver). In the digital broadcast receiver, the user (viewer) sets the operation state and life cycle of the MHP application based on the AIT (Application Information Table) according to whether the automatic control by the receiver is valid or invalid for each service. It can be set. Here, AIT is data (application control information) including information for application control (activation, termination, destruction, etc.).

In the digital broadcast receiver according to the first embodiment, a user (viewer) can automatically operate an operation mode (hereinafter, referred to as an operation state of an MHP application based on the AIT by the receiver) for each service. Simply abbreviated as “operation control mode”) can be set to either the AutoStart_ON mode or the AutoStart_OFF mode. In the digital broadcast receiver according to the first embodiment, the user sets the operation control mode of the receiver for a predetermined service in advance, thereby indicating the operation control mode to be applied to the service. When the service is stored and the service is selected (tuned) thereafter, the receiver refers to the data indicating the operation control mode set for the service, and the operation state of the MHP application based on the AIT of the service It is determined whether or not the automatic control is executed.

In the present embodiment, the term “service” means a program distinguished by PMT (Program Map Table). The “service” includes a program that is regularly broadcast with a predetermined regularity (broadcast time, day of the week, etc.). In the present embodiment, a plurality of programs that are broadcast according to the predetermined regularity. Is regarded as a unit for setting automatic control validity / invalidity based on AIT, and it is possible to simply set validity / invalidity of automatic control of AIT for a plurality of programs. Alternatively, it is possible to enable / disable automatic control based on the AIT according to the content of services such as sports broadcasts, news, and variety shows.

In the digital broadcast receiver according to the first embodiment, since the user (viewer) can set the operation control mode (AutoStart_OFF, AutoStart_ON) in advance for each service, the user (viewer) switches the service ( There is no need to manually switch the operation control mode to a desired mode when selecting (or selecting). For example, when the receiver according to the present embodiment selects a service in which the operation control mode of AutoStart_OFF is set and the user (viewer) does not want to automatically control the operation state of the MHP application by the receiver, The automatic control of the MHP application based on the AIT is automatically turned off (AutoStart_OFF operation control mode), and conversely, the user (viewer) selects a service that the receiver wants to automatically control the operation state of the MHP application by the receiver. In this case, the automatic control of the MHP application based on the AIT is automatically turned on (AutoStart_ON operation control mode).

Note that the digital broadcast receiving method according to the first embodiment is also implemented in the digital broadcast receiver, so that the same effect as described above can be obtained.

In the present specification, “MHP application” includes all applications conforming to the MHP standard, and for example, “DVB-J application” is included in the “MHP application”. For example, the MHP application includes an EPG application, a game application, a weather forecast application, and the like, all of which are applications downloaded and acquired by the receiver 100 from a broadcasting station. However, although the present embodiment relates to automatic control of the operation state of the MHP application based on the AIT, this means that the present invention is limited to automatic control of the operation state of the MHP application based on the AIT. Not what you want. The following embodiments are presented solely for the purpose of illustrating the present invention.

Further, the digital broadcast receiver according to the first embodiment has a function of caching the MHP application extracted from the broadcast wave in a predetermined storage area. The cache function according to the MHP application is performed based on favorite registration information registered in the receiver. That is, the MHP application included in the service registered in the favorite registration information or the like is preferentially cached. At this time, the receiver refers to the setting of the operation control mode of the MHP application set for the service registered in the favorite registration information or the like, and is included in the service whose operation control mode is set to the AutoStart_ON mode. The MHP application to be cached is more preferentially cached. By doing so, the MHP application of the service that the user (viewer) often sees and the operation control mode of the MHP application is set to the mode of AutoStart_ON is cached with the highest priority, The process of extracting the MHP application from the broadcast wave is omitted as appropriate, and the use efficiency of the storage area used for the cache is improved. Even when deleting the cached and held MHP application, the digital broadcast receiver according to the first embodiment can determine whether or not to delete the cached MHP application in the same manner as the above-described priority order. It is.

Also, the digital broadcast receiving method implemented in the digital broadcast receiver according to the first embodiment is implemented in the digital broadcast receiver as a computer-executable program. The program can be provided to the digital broadcast receiver via a portable storage medium or a communication line. The provided program is held in a storage device or the like connected to the digital broadcast receiver, and is appropriately read and executed by a processing device (for example, CPU) of the digital broadcast receiver.

The control unit 7 is a controller realized by arithmetic processing by a central processing unit (CPU) and a program executed in the CPU, and this controller controls the entire receiver 100. For example, the control unit 7 demodulates (selects) a predetermined service to the tuner unit 1 in accordance with a key code indicating a key pressed in the remote controller 19 input from the remote controller reception unit 15. Instruct. Further, for example, the control unit 7 manages the operation state (startup, termination, etc.) and life cycle (deletion, etc.) of the MHP application based on the AIT related to the service, and stores necessary files from the object carousel to the storage unit 17 (memory, etc.). ) To download. The control unit 7 can instruct the MHP application execution unit 9 to execute a predetermined MHP application.

The MHP application execution unit 9 includes a Java virtual machine defined by DVB-MHP. Based on an instruction from the control unit 7, the MHP application execution unit 9 reads and executes the MHP application file held in the storage unit 17. Similarly to the control unit 7, the MHP application execution unit 9 may also be realized by a central processing unit (CPU) and arithmetic processing by a program executed on the CPU. Alternatively, the MHP application execution unit 9 may be realized by a dedicated circuit.

The combining unit 11 combines the decoded video data and audio data input from the AV decoder unit 5 with the video data related to the MHP application input from the MHP application executing unit 9 and outputs the video / audio. To the unit 13. The combining unit 11 is preferably configured to include a dedicated circuit.

The video / audio output unit 13 outputs the synthesized video data input from the synthesis unit 11 to the video display unit 301 such as a monitor, and outputs the (after synthesis) audio data to the audio output unit 303 such as a speaker. .

The remote controller receiving unit 15 receives data (user operation information) sent from the remote controller 19 via the wireless transmission path, analyzes the data, and displays the keys operated in the remote controller 19 and the contents of the operation. It outputs to the control part 7 as the key code which is the data to show. For example, the user (viewer) operates the remote controller 19 to input various settings such as the setting of the operation control mode of the MHP application to the control unit 7 via the remote controller reception unit 15, It is possible to input an instruction to select (select) a service (including data broadcasting) to be performed.

The storage unit 17 is a storage unit (data storage area) configured by a storage device such as a (volatile) memory, a hard disk drive (HDD), or a nonvolatile memory. The storage unit 17 holds the object carousel of the MHP application in a state that the control unit 7 or the MHP application execution unit 9 can refer to as one or a plurality of files (MHP application cache 171c (FIG. 2)). An MHP application holding unit 171 (FIG. 2) that provides the file to the MHP application execution unit 9 or the like according to a request from the application execution unit 9 or the like is included. In addition, the storage unit 17 sets data for an operation control mode (current operation control mode information) set for the currently selected (tuned) service or one or a plurality of predetermined services. A data management unit 173 (FIG. 2) that stores data (MHP application activation information) indicating the operation control mode of the MHP application that has been performed is included.

<Functional configuration>
FIG. 2 is a block diagram for explaining functions realized by the control unit 7, the MHP application execution unit 9, and the storage unit 17 of the receiver 100. This function can be realized by an arithmetic processing unit such as a central processing unit and a program executed in the processing unit.

The control unit 7 has functions as an operating system (OS) 71, an MHP application operation control mode setting management unit 73, a channel selection unit 75, a key distribution mode management unit 77, a key distribution unit 79, and a built-in application management unit 81. The MHP application management unit 83 is a function (module) that is activated by the built-in application management unit 81 when executing an MHP application. The built-in applications (1) and (2) (85 and 87) are installed at the time of shipment, or installed in the receiver 100 via a network or a storage medium such as an SD card, and stored in the storage unit 17 of the receiver 100. The built-in applications are read from the storage unit 17 as appropriate and executed by the built-in application management unit 81. Examples of the built-in application include a child lock application and a banner application.

The operating system (OS) 71 is software having a function for controlling and managing the entire receiver 100.

The MHP application operation control mode setting management unit 73 allows the user (viewer) to use the remote controller 19, the video display unit 301, and the like (both in FIG. 1) as a user interface, and to the receiver 100 regarding a specific service. A function for inputting the setting of the operation control mode of the MHP application is provided. The setting information input to the receiver 100 through the function is held as the MHP application activation information 173b in the data management unit 173 of the storage unit 17 and is referred to by the control unit 7 as appropriate. Further, the MHP application operation control mode setting management unit 73 generates data indicating the operation control mode set for the currently selected (tuned) service, and performs data management as the current operation control mode information 173a. A function of storing in the unit 173;

The channel selection unit 75 instructs the tuner unit 1 to select a service (channel selection) based on the channel selection request from the built-in application management unit 81.

The key distribution mode management unit 77 recognizes the applications (built-in application and MHP application) currently operating in the receiver 100, and determines the key distribution mode to be one of mode 1 and mode 2 based on the recognition. . More specifically, the key distribution mode management unit 77 monitors the presence or absence of an MHP application that is currently operating in the receiver 100, and determines that the key distribution mode is mode 1 if there is no MHP application that is operating. If at least one MHP application is in operation, the key distribution mode is determined as mode 2. The determined setting value of the key delivery mode is stored in the key delivery mode management unit 77 as key delivery mode data 77a. In a situation where the key delivery mode management unit 77 determines the key delivery mode to be mode 1, the key delivery unit 77 sends the key code received from the remote controller reception unit 15 to the built-in application management unit 81. In a situation where the key delivery mode management unit 77 has determined that the key delivery mode is mode 2, the key delivery unit 77 sends the key code received from the remote controller reception unit 15 to the MHP application management unit 83.

The key distribution unit 79 outputs (distributes) the key code received from the remote controller reception unit 15 through the OS 71 to at least one of the built-in application management unit 81 and the MHP application management unit 83. When the key delivery unit 79 determines the delivery destination of the key code, the key delivery unit 79 refers to the key delivery mode data 77a determined and managed by the key delivery mode management unit 77, and based on the key delivery mode data 77a, the key delivery mode data 77a Determine the delivery destination. However, the key delivery unit 79 delivers (outputs) the key code of a predetermined specific key (built-in application dedicated key) to the built-in application management unit 81 regardless of the key delivery mode. To do. Here, the built-in application dedicated keys include, for example, channel up (Channel Up), channel down (Channel Down), volume up (Volume Up), volume down (Volume Down), power on (Power On ), Operation keys to which functions such as power off are assigned. The key codes of these specific keys (dedicated built-in application keys) are always delivered to the built-in application management unit 81 even when the MHP application is operating in the receiver 100.

The built-in application management unit 81 executes built-in application operation control (startup, etc.) and key code delivery control for the built-in application. Also, the built-in application management unit 81 receives an instruction (channel selection instruction, etc.) from the built-in application (85, 87, etc.) and MHP application (171a, 171b, etc.), and a block related to the instruction (channel selection unit 75, etc.) It also has a function to send to.

Further, the built-in application management unit 81 determines whether the TS demodulated by the tuner unit 1 (FIG. 1) includes information related to the AIT based on the channel selection instruction of the channel selection unit 75, and is currently selected. When the AIT is included in the service TS, the MHP application management unit 83 can be activated based on the AIT and the MHP application activation information 173b for the service.

Specifically, the built-in application management unit 81 refers to a PMT (Program Map) included in the TS, detects the PID of the AIT, and extracts the AIT based on the PID. Then, the built-in application management unit 81 uses the AIT to describe an instruction related to operation control such as activation and stop of the MHP application, description of link information to an object carousel to which the MHP application is delivered, and an MHP application. A description of information necessary for MHP application control, such as the path of a file used at startup, and a description about the life cycle of the MHP application are extracted, and the operation control and life of the MHP application such as “application_type” and “application_control_code” are extracted. Referring to the description related to cycle control and the like, if the AIT is instructed to automatically start (such as AUTOSTART) an MHP application (such as DVB-J application), the MHP application management unit 83 is activated. However, when the MHP application activation information 173b for the service referred to in conjunction with the AIT indicates the MHP application operation control mode “AutoStart_OFF”, the built-in application management unit 81 sets “application_control_code” of the AIT to “AUTOSTART”. Even if it is specified, it is possible not to start the MHP application management unit 83.

The MHP application management unit 83 is middleware that manages the execution of the MHP application. The MHP application management unit 83 performs operation control (startup, etc.) of the MHP application and key distribution for the MHP application based on information described in the AIT via the built-in application management unit 81.

Next, the MHP application execution unit 9 will be described.
The MHP application execution unit 9 includes a virtual machine (VM unit 91) that executes the MHP applications 1, 2 and the like (171a, 171b, etc.) and various APIs (channel selection API 93a, drawing API 93b, etc.). The VM unit 91 executes the MHP application (171a, 171b, etc.) under the management of the MHP application management unit 83. The MHP application can call the functions of the receiver 100 as appropriate by using various APIs (93a, 93b, etc.). In receiver 100 according to the present embodiment, a call from an MHP application through API is sent to a predetermined block from API (93a or the like) through built-in application management unit 81. For example, when the MHP application 1 (171a) is an EPG application and the service is selected based on the delivered key code, the MHP application 1 (171a) selects the channel using the channel selection API 93a. Station instructions can be output. The channel selection instruction is once sent to the built-in application management unit 81, and the built-in application management unit 81 sends the channel selection instruction to the channel selection unit 75.

Finally, the storage unit 17 will be described.
The storage unit 17 has a function of holding various data used by the receiver 100. In particular, the storage unit 17 includes an MHP application holding unit 171 that holds data related to the MHP application, and a data management unit 173 that holds data related to operation control of the MHP application.

The MHP application holding unit 171 is a storage area that holds data related to the MHP application extracted from the object carousel in a file format (cached MHP application 171c) that can be referred to by the control unit 7 and the MHP application execution unit 9. is there. The receiver 100 downloads the MHP application included in the service whose MHP application operation control mode is set to AutoStart_ON in the MHP application activation information 173b in advance (before selecting the service) from the broadcast wave, The MHP application holding unit 171 may cache and hold the MHP application 171c. Further, every time a service whose MHP application operation control mode is set to AutoStart_ON in the MHP application activation information 173b is selected (channel selection), the receiver 100 is designated as “AUTOSTART” in the “application_control_code” of the AIT of the service. The downloaded MHP application may be downloaded from the broadcast wave.

The data management unit 173 displays the current operation control mode information 173a, which is data indicating the operation control mode set for the currently selected (tuned) service, and the operation of the MHP application set for a predetermined service. This is a storage area for holding MHP application activation information 173b, which is data indicating the control mode.

<MHP application operation control by receiver>
Hereinafter, the operation control of the MHP application performed by the receiver 100 according to the present embodiment will be described in detail. First, the operation control of the MHP application performed by the digital broadcast receiver according to the conventional technique will be briefly described, and then the operation control of the MHP application performed by the receiver 100 according to the present embodiment will be described in detail.

FIG. 3 is an example diagram for explaining an example of operation control of an MHP application based on AIT by a conventional digital broadcast receiver.

FIG. 3A shows an AIT (service A AIT) related to a predetermined service (service A).
FIG. 3B shows an AIT (service B AIT) related to a predetermined service (service B) different from the service A. In the conventional digital broadcast receiver, the operation control mode of the MHP application can be set to either the AutoStart_ON mode or the AutoStart_OFF mode for the receiver.

FIG. 3C is a table showing the operation control of the MHP application performed by the receiver when the AutoStart_ON mode is set in the conventional receiver. In a conventional digital broadcast receiver, when the AutoStart_ON mode is set for the receiver, all the selected services (both service A and service B in the figure) are selected. The operation control of the MHP application is automatically executed based on the AIT related to the service provided. As can be seen from FIGS. 3A to 3C, with the conventional receiver, as long as the AutoStart_ON mode is set, if the service A is selected, the MHP application is based on the service A AIT. The operation control is automatically performed. Similarly, when the service B is selected, the operation control of the MHP application is automatically performed based on the service B AIT. Here, the MHP application for which “AUTOSTART” is designated is automatically activated simultaneously with the selection of the service, and the MHP application for which “PRESENT” is designated is being executed when the service is selected. The execution state is continued. For example, when the service to be selected is switched from the service B to the service A, the MHP application 1 is activated (in this case, the execution state is continued), and the execution state of the MHP application 2 is also continued. Is made. Since the MHP application 3 was not activated in the service B that was selected immediately before the selection of the service A, it is not newly activated in the service A.

FIG. 3D is a table showing operation control of the MHP application performed by the receiver when the AutoStart_OFF mode is set in the conventional receiver. In the conventional digital broadcast receiver, when the AutoStart_OFF mode is set for the receiver, the AIT is used for all currently selected services (both service A and service B in the figure). The description of “application_control_code” is replaced with “KILL”, for example, and automatic operation control of the MHP application based on the AIT is executed. As can be seen from FIGS. 3A, 3B, and 3D, in the conventional receiver, as long as the service A is selected as long as the AutoStart_OFF mode is set, the service A is selected. The description of the “application_control_code” in the AIT is replaced with “KILL”, and the operation control of the MHP application based on the AIT is automatically performed. Similarly, when the service B is selected, the description of “application_control_code” of the service B AIT is replaced with “KILL”, and the operation control of the MHP application based on the AIT is automatically performed. Here, the value after the replacement of the description of “application_control_code” may be a value other than “KILL”.
Alternatively, in the conventional receiver, as long as the AutoStart_OFF mode is set, the AIT extraction performed by referring to the PMT and the operation control of the MHP application performed automatically based on the AIT are not performed. In addition, it is possible to terminate the manager of the MHP application.

FIG. 4 is an example of a screen displayed on the video output unit 301 (FIG. 1) when the MHP application is executed in the conventional receiver or the receiver 100 according to the present embodiment. FIG. 4A shows an execution example of the MHP application APL1, and FIG. 4B shows an execution example of the MHP application APL2 different from the MHP application APL1. These two types of MHP applications APL1 and APL2 are both EPG applications. However, the specifications of the operation keys used for channel selection differ between the two applications. The MHP application APL1 in FIG. 4A has a specification that the channel selection is performed using only the left and right direction keys. On the other hand, the MHP application APL2 in FIG. 4B has a specification in which channel selection is performed using the up / down direction key and the determination key.

Generally, in an EPG application that is a kind of MHP application, which key of an operation key provided in a user interface such as the remote controller 19 (FIG. 1) is assigned to service switching by the EPG application depends on the person who provides the MHP application ( For example, it is left to the discretion of the broadcasting station). Therefore, when the key code is input from the remote controller 19 (FIG. 1) and the key code is delivered to the EPG application that is the MHP application, the receiver 100 or the like starts any operation with the key code. I can't know. The receiver 100 or the like displays the content of the operation assigned to the key code only when an operation instruction based on the key code is sent from the EPG application (MHP application) to the built-in application management unit 81 (FIG. 1). Indirect but can know.

As described above, when the MHP application is executed in the digital broadcast receiver, some of the remote controller operation keys are occupied by the MHP application. When a part of the operation keys is occupied by the MHP application, an operation performed by the user using the operation key before the MHP application is started may not be executed. In order to avoid such a situation well, in the receiver 100 according to the present embodiment, the user (viewer) turns on / off automatic control of the operation state of the MHP application based on the AIT in advance for each service. Can be set to By doing so, the user (viewer) sets off automatic control of the operation state of the MHP application based on the AIT in advance for a specific service, and a part of the operation by the MHP application is performed for viewing the service. In order to avoid occupancy of the key and operational inconvenience caused by it, and for another specific service, the automatic control of the operation state of the MHP application based on the AIT is set to ON in advance. A predetermined MHP application is automatically started simultaneously with service selection (channel selection), and the troublesomeness of starting the MHP application from the application list by manual operation can be avoided.

<MHP application operation control mode setting process>
FIG. 5 is a flowchart of the MHP application operation control mode setting process in the receiver 100 according to the present embodiment. In the receiver 100 according to the present embodiment, the setting of ON / OFF of the MHP application operation control based on the AIT (AutoStart_ON mode / AutoStart_OFF mode) can be set in advance for each service by this processing.

In step S101, the MHP application operation control mode setting management unit 73 (FIG. 2) accepts selection of a service that is a target for setting the operation control mode of the MHP application from the user (viewer). The selection may be accepted using the remote controller 19, the video display unit 301, the audio output unit 303, etc. as a user interface.

Next, in step S103, the MHP application operation control mode setting management unit 73 (FIG. 2) selects the operation control mode of the MHP application to be set for the service selected in step S101 from the user (viewer). Accept. In this step, selection of AutoStart_ON or AutoStart_OFF is accepted. In addition, a setting input such as a replacement rule for rereading and executing the description of “application_control_code” of the AIT may be received. For example, for a service for which AutoStart_OFF is set, the AIT “application_control_code” description “AUTOSTART” is read as “PRESENT”, and a description other than “AUTOSTART” is read as “KILL”. It is possible to make it execute.

In step S105, the MHP application operation control mode setting management unit 73 (FIG. 2) associates the operation control mode received in step S103 with the service received in step S101, as MHP application activation information 173b for the service. The data is stored in the data management unit 173 (FIG. 2).

FIG. 6 is an exemplary diagram for explaining an example of operation control of the MHP application based on the AIT by the receiver 100 according to the present embodiment.

6 (a) and 6 (b) are AITs related to service A and service B, similar to FIGS. 3 (a) and 3 (b).

FIG. 6C shows that the automatic control of the operation state of the MHP application based on the AIT for the service A is set to ON (AutoStart_ON mode), and the automatic control of the operation state of the MHP application based on the AIT for the service B is turned off (AutoStart_OFF). This is a table showing the operation control of the MHP application performed by the receiver 100 when the (mode) is set.
When the service A is selected (channel selection), the receiver 100 extracts the AIT (FIG. 6A) of the service A, and automatically executes the operation control of the MHP application based on the description of the AIT. To do. Specifically, when the service A is selected (tuned), the receiver 100 activates the MHP application 1 (description “AUTOSTART” of “application_control_code”), and the MHP application 2 and the MHP application 3 If it is being executed, the execution is continued (description “PRESENT” of “application_control_code”).
After service A is selected (tuned) in this way, when service B is selected (tuned), receiver 100 stops all MHP applications. When the receiver 100 is in a service in which the operation control mode of the MHP application is set to OFF (AutoStart_OFF), the MHP application (MHP application 1, MHP application 2, MHP application 5) described in the AIT of the service. All other MHP apps are also stopped. Alternatively, referring to AIT, “AUTOSTART” is replaced with a predetermined description other than “AUTOSTART” (for example, “PRESENT”, and “Description other than AUTOSTART” in AIT is replaced with “KILL”, and the MHP application based on AIT It is also possible to control the operation state and the like.
Furthermore, when the channel selection change to the service B is performed based on a channel selection instruction from the MHP application, the receiver 100 continues the execution without stopping the MHP application. Can be. By doing so, it is possible to prevent the MHP application used by the user (viewer) from suddenly ending after a service change (channel selection). If the AIT of service B includes a description for stopping the execution of the MHP application, the MHP application may also be stopped.

<Key code delivery processing>
Next, a key code delivery process in the receiver 100 will be described with reference to FIGS. The key code delivery process is based on the key code output from the remote controller receiving unit 15 (FIG. 1) to the control unit 7 (FIG. 1) when an operation key such as the remote controller 19 (FIG. 1) is pressed. These processes are performed in the control unit 7 and the MHP application execution unit 9. FIG. 7 is a flowchart of the key code delivery process, and FIG. 8 is a schematic diagram showing a data flow related to the key code delivery process.

When the user (viewer) operates the operation key of the remote controller 19, the remote controller 19 transmits user operation information 101. The remote controller receiving unit 15 receives the user operation information 101 transmitted from the remote controller 19, analyzes the user operation information, converts it into a key code, and converts the key code 103 into the operating system (OS) of the control unit 7. ) 71. (Fig. 8)

In step S <b> 201, the OS 71 checks whether or not a key code is input from the remote controller receiving unit 15.
When the OS 71 detects the input of the key code (“YES” in step S201), the process proceeds to step S203.
When the OS 71 does not detect the input of the key code (“NO” in step S201), the key code delivery process ends. (Fig. 7)

The key code 103 received by the OS 71 is sent to the key delivery unit 79 (key code 105). (Fig. 8)

In step S203, the key delivery unit 79 determines whether or not the key code 105 is a key code for a built-in application dedicated key.
If the key delivery unit 79 determines that the key code 105 is a key code for the built-in application dedicated key (“YES” in step S203), the process proceeds to step S205.
If the key delivery unit 79 determines that the key code 105 is not the key code for the built-in application key (“NO” in step S203), the process proceeds to step S207. (Fig. 7)

In step S205, the key delivery unit 79 outputs a key code to the built-in application management unit 81 (key code 107 in FIG. 8).

In step S207, the key delivery unit 79 refers to the current key delivery mode setting value (key delivery mode data 77a) held by the key delivery mode management unit 77. (Arrow 113 in FIGS. 7 and 8)

In step S209, the key delivery unit 79 checks whether or not the current key delivery mode setting value acquired with reference to the key delivery mode data 77a is mode “1”.
If the key delivery unit 79 determines that the current key delivery mode setting value is “1” (“YES” in step S209), the process proceeds to step S205.
If the key delivery unit 79 determines that the current key delivery mode setting value is not “1” (“2”) (“NO” in step S209), the process proceeds to step S211.

In step S211, the key delivery unit 79 outputs a key code to the MHP application management unit 83 (key code 115 in FIG. 8).

As described above, the receiver 100 sends the key code of the dedicated key for the built-in application to the built-in application management unit 81 regardless of the set value of the key delivery mode, and the key code of the operation key other than the dedicated key for the built-in application. When the set value of the key delivery mode is mode “1”, it is sent to the built-in application management unit 81, and when the set value of the key delivery mode is mode “2”, it is sent to the MHP application management unit 83. The key code delivery process is performed.

Referring to FIG. 8, execution of control unit 7 and MHP application in relation to the key code (107 and 115) delivered to either built-in application management unit 81 or MHP application management unit 83 by the key code delivery processing of FIG. The process executed by the unit 9 will be briefly described.

Key code (key code 107) delivered to the built-in application management unit 81:
The key code 107 is sent from the built-in application management unit 81 to a built-in application (for example, built-in application (1) 85). The built-in application that has received the key code executes a predetermined process based on the key code, and returns a predetermined instruction (for example, a channel selection instruction 109) to the built-in application management unit 81 as necessary. The built-in application management unit 81 that has received the instruction from the built-in application sends the instruction to an appropriate block according to the content of the instruction. For example, when the built-in application management unit 81 receives the channel selection instruction 109 from the built-in application (1) 85, the built-in application management unit 81 sends a channel selection instruction 111 to the channel selection unit 75. Also, the built-in application management unit 81 entrusts the processing related to the basic operation of outputting a channel selection instruction to the channel selection unit 75 based on the delivered key code, and performs internal processing. It may be configured to be able to.

Key code (key code 115) delivered to the MHP application management unit 83:
The key code 115 is sent from the MHP application management unit 81 to the VM unit 91 of the MHP application execution unit 9. The VM unit 91 (the MHP application) that has received the key code 117 executes a predetermined process based on the key code, and uses a predetermined instruction (for example, the API) to the built-in application management unit 81 (for example, The channel selection instruction 121) is returned. The built-in application management unit 81 that has received the instruction from the MHP application sends the instruction to an appropriate block according to the content of the instruction. For example, when the built-in application management unit 81 receives the channel selection instruction 121 from the MHP application 171a through the channel selection API 93a, the built-in application management unit 81 sends a channel selection instruction 123 to the channel selection unit 75.

Upon receiving the

channel selection instruction

111 or 123, the channel selection unit 75 sends a channel selection instruction to the tuner unit 1 (FIG. 1) based on the

channel selection instruction

111 or 123.

As described above, in the receiver 100, the key code of the built-in application dedicated key is always processed in the built-in application, and the instruction that the built-in application outputs in response to the input of the key code is the built-in application management unit. By being sent to a predetermined block via 81, the operation by the key code is realized. The key codes of the operation keys other than the built-in application dedicated key are distributed to the built-in application management unit 81 or the MHP application management unit 83 based on the key delivery mode setting value held in the key delivery mode management unit 77. The key code sent to the MHP application management unit 83 is processed in the MHP application being executed in the MHP application execution unit 9. Then, the MHP application sends a predetermined instruction according to the key code to the built-in application management unit 81 using an appropriate API. The built-in application management unit 81 sends the received instruction to a predetermined block. In this way, an operation using the key code is realized. At this time, the built-in application management unit 81 can identify whether the received instruction is an instruction output from the built-in application or an instruction output from the MHP application.

<MHP application operation control process when selecting a service>
In FIG. 9, the built-in application management unit 81 receives a channel selection instruction, sends a channel selection instruction to the channel selection unit 75 (FIGS. 2 and 8) based on the channel selection instruction, and controls the operation of the MHP application. It is a flowchart which shows the process to perform.

In step S301, the key delivery unit 79 sends a key code to the built-in application management unit 81. The key code is sent from the built-in application management unit 81 to the built-in application. The built-in application that has received the key code executes a predetermined process based on the key code, and returns a predetermined instruction to the built-in application management unit 81 as necessary. Alternatively, when the key delivery unit 79 sends a key code to the MHP application management unit 83, a predetermined instruction is returned from the MHP application execution unit 9 to the built-in application management unit 81 as necessary.

In step S303, the built-in application management unit 81 determines whether or not the received instruction is a channel selection instruction.
If the built-in application management unit 81 determines that the received instruction is a channel selection instruction (“YES” in step S303), the process proceeds to step S305.
When the built-in application management unit 81 determines that the received instruction is not a channel selection instruction (“NO” in step S303), the service selection MHP application control process illustrated in FIG. 9 ends.

In step S305, the built-in application management unit 81 notifies the channel selection unit 75 of a channel selection instruction, and the channel selection unit 75 (FIG. 1), the OS 71 (FIG. 2), and the channel selection unit 75 (FIG. 2) perform the selection. A PMT related to the service selected by the station instruction is acquired, a description (PID or the like) related to the AIT related to the service is searched, and the presence or absence of the AIT related to the service is checked.

In step S307, the built-in application management unit 81 determines whether there is an AIT related to the service from the PMT.
If the built-in application management unit 81 determines that an AIT exists (“YES” in step S307), the process proceeds to step S309.
If the built-in application management unit 81 determines that no AIT exists (“NO” in step S307), the process proceeds to step S321.

In step S309, the built-in application management unit 81 acquires the MHP application activation information 173b.

In step S311, the built-in application management unit 81 determines, based on the acquired MHP application activation information 173b, whether the MHP application operation control mode set for the service related to the channel selection is AutoStart_ON / OFF.
If the built-in application management unit 81 determines that the MHP application operation control mode for the service is AutoStart_ON (“ON” in step S311), the process proceeds to step S313.
If the built-in application management unit 81 determines that the MHP application operation control mode for the service is AutoStart_OFF (“OFF” in step S313), the process proceeds to step S321.

In step S313, the built-in application management unit 81 determines whether there is an MHP application currently being executed. The MHP application that is currently being executed is an MHP application that has been executed in a service provided before channel selection. This determination may be performed by various methods. For example, it may be determined from the current operation control mode information 173a, AIT, etc. related to the service immediately before channel selection. Alternatively, it may be checked whether the MHP application management unit 83 is activated.
When the built-in application management unit 81 determines that there is an MHP application currently being executed (“YES” in step S313), the process skips to step S319.
If the built-in application management unit 81 determines that there is no currently executing MHP application (“NO” in step S313), the process proceeds to step S315.

In step S315, the built-in application management unit 81 activates the MHP application management unit 83.

In step S317, the built-in application management unit 81 sends an instruction to the key delivery mode management unit 77 to change the key delivery mode setting value (key delivery mode data 77a) to mode “2”. Based on the instruction, the key delivery mode management unit 77 changes the key delivery mode setting value (key delivery mode data 77a) to mode “2”. The built-in application management unit 81 updates the current operation control mode information of the data management unit 173.

In step S319, the built-in application management unit 81 executes operation control and life cycle management of the MHP application based on the AIT of the selected service. Accordingly, the MHP application management unit 83 instructs the MHP application execution unit 9 to execute / stop a predetermined MHP application. In response to the instruction, the MHP application execution unit 9 starts activation of a predetermined MHP application.

On the other hand, if the built-in application management unit 81 determines in step S307 that the AIT does not exist, the process proceeds to step S321.

In step S321, the built-in application management unit 81 determines whether or not there is an MHP application currently being executed, as in step S313.
If the built-in application management unit 81 determines that there is a currently executing MHP application (“YES” in step S321), the process proceeds to step S323.
When the built-in application management unit 81 determines that there is no MHP application currently being executed (“NO” in step S321), the service selection MHP application control process illustrated in FIG. 9 ends. At the end, the built-in application management unit 81 updates the current operation control mode information 173a and the key distribution mode data 77a.

In step S323, the built-in application management unit 81 determines whether or not the channel selection instruction related to the determination in step S303 is a channel selection instruction output from the MHP application. The MHP application that outputs a channel selection instruction is, for example, an EPG application. Such an MHP application can output a channel selection instruction to the built-in application management unit 81 using, for example, the channel selection API 93a (FIG. 8).
If the built-in application management unit 81 determines that the channel selection instruction is a channel selection instruction output from the MHP application (“YES” in step S323), the process proceeds to step S325.
When the built-in application management unit 81 determines that the channel selection instruction is not a channel selection instruction output from the MHP application (for example, a channel selection instruction from the built-in application) (“NO” in step S323), the process is performed as a step. The process proceeds to S327.

In step S325, the built-in application management unit 81 continues the execution of the MHP application (EPG application) that has output the channel selection instruction among the currently executed MHP applications, and stops the execution of the other MHP applications that are being executed. . Then, the service selection MHP application control process shown in FIG. At the end, the built-in application management unit 81 updates the current operation control mode information 173a and the key distribution mode data 77a.

In step S327, the built-in application management unit 81 stops the execution of all currently executed MHP applications. Then, the service selection MHP application control process shown in FIG. At the end, the built-in application management unit 81 updates the current operation control mode information 173a and the key distribution mode data 77a.

As described above, the digital broadcast receiver according to the first embodiment can set the operation control mode (AutoStart_OFF, AutoStart_ON) for each service. By doing so, when a user (viewer) switches (selects) a service, the service can be switched under a desired operation control mode without manually switching the operation control mode. The operability of the broadcast receiver is greatly improved.
