  FIG. 4 shows main streams and information in the broadcast wave transmission line 2100 and the hybrid cast transmission line 2200. Each transmission path transmits a video stream, an audio stream, application control information, and service information. In the hybrid cast transmission line 2200, there is not only a downstream stream from the service provider apparatus 3000 to the receiver 5000 but also an upstream stream from the receiver 5000 to the service provider apparatus 3000.

  FIG. 5 is a diagram illustrating a schematic configuration example of a receiver 5000 to which the embodiment is applied. The receiver 5000 includes a first processing unit (also referred to as a communication content processing unit) 5100 of a hybrid cast specification connected to a network, and a second processing unit (also referred to as a broadcast content processing unit) for receiving broadcast waves. Good) 5300. The network is connected to the previous service provider device 3000.

  The first processing unit 5100 includes an IP communication interface 5101. The stream captured via the IP communication interface 5101 is received by the streaming reception processing unit 5102, and the demodulated stream is restored to the original arrangement state by the demultiplexer 5103. A DRAM processing unit 5104 is connected to the demultiplexer 5103, and the DRAM processing unit 5104 can operate a program and execute, for example, automatic download.

  The video stream separated by the demultiplexer 5103 is decoded by a video decoder 5111, the audio stream is decoded by an audio decoder 5112, and the subtitle stream is decoded by a subtitle decoder 5113.

  The decoded video data and subtitle data can be combined by the combiner 5501 and input to the display 5002. The decoded audio data can be input to the speaker system via the synthesizer 5502.

  The second processing unit 5300 includes a broadcast tuner 5301. The stream received and demodulated by broadcast tuner 5301 is input to descrambler 5302. In the descrambler 5302, the input stream is descrambled with a key from a CAS (Conditional Access System) module 5304. The stream descrambled by the descrambler 5302 is input to the demultiplexer 5303. Demultiplexer 5303 outputs data for data broadcast to data broadcast reception processing section 5330. The video stream separated by the demultiplexer 5303 is decoded by a video decoder 5311, the audio stream is decoded by an audio decoder 5312, and the subtitle stream is decoded by a subtitle decoder 5313. The decoded video data and subtitle data can be combined by the combiner 5501 and input to the display 5002. The decoded audio data can be input to the speaker system 5003 via the synthesizer 5502.

For example, it has an application authentication function and handles an authenticated application as a management application. It also has an access control function, a presentation function, an enforcement function, a revocation function (a function for a management application outside the broadcast), and the like.

  The access control function allows a broadcast resource (video, audio, metadata SI information, etc.) and a receiver resource (video / audio output of the receiver, a network interface, etc.) to be referred to the application permitted to use. In addition, the receiver API that can be accessed is restricted according to the security class of the application.

  The presentation control function determines the display method of the application (whether or not to overlay a broadcast moving image, the display area and size, display / non-display, etc.) based on the intention of the broadcaster. Further, in an emergency such as a disaster report, for example, the application or its related display is temporarily hidden so that the full-screen display of the broadcast program can be controlled.

  The revocation function is a function that can invalidate a problematic application that impairs the interests of broadcasters and users.

  The application engine 5130 forms an environment for executing an application. As the application engine 5130, for example, an HTML5 browser equipped with an extended API for supporting hybrid casting is used.

<Explanation related to the hybrid cast specification>
Meanwhile, the broadcast station 1000 in FIG. 1 is configured to transmit a broadcast signal including, for example, 2K, 4K, or 8K high-resolution content to the receiver 5000 side. The service provider 3000 that develops a service business in cooperation with the broadcasting station 1000 distributes applications to the receiver 5000 using the Internet, for example, so that various services can be provided. To provide this service, HTML5 (or a later version of HTML) can be used. As an application to be distributed, a script-type computer program (such as JavaScript (registered trademark) using Java (registered trademark) or ECMA script) that can be embedded in an HTML document can be used. (Hereinafter, this computer program is abbreviated as “script” as appropriate. In the embodiment, JavaScript can be used as the script.)
Scripts embedded in HTML (HTML5 or later) can include various functions. For example, when making a viewing or recording reservation, the functions described in Part 2 of ARIB STD-B62 (Multimedia Coding System Language Specification) and Part 3 of ARIB TR-B39 (Operational Rules for Advanced BS Digital Broadcasting Multimedia Services) Can be included in the script. An example is shown below:
partial interface ReceiverDevice {
boolean isScheduledToTune (
ISDBResourceReference event_ref,
optional Date startTime);
void scheduleToTune (
ISDBResourceReference event_ref,
optional Date startTime);
void unscheduleToTune (
ISDBResourceReference event_ref);
boolean isScheduledToRecord (
ISDBResourceReference event_ref,
optional Date startTime);
void scheduleToRecord (
ISDBResourceReference event_ref,
optional Date startTime);
void unscheduleToRecord (
ISDBResourceReference event_ref);}; ……….

  In the above example, “isScheduledToTune ()” and “scheduleToTune ()” are functions related to viewing reservation (see FIGS. 8A and 8B), and “isScheduledToRecord ()” and “scheduleToRecord ()” are recording reservations. (See FIGS. 8D and 8E), and “unscheduleToTune ()” and “unscheduleToRecord ()” are functions related to canceling a reservation (see FIGS. 8C and 8F). The viewing reservation function, the recording reservation function, the reservation cancellation function, and the like are functions that are appropriately used by the transmitting side (broadcasting station and / or service provider) and are appropriately executed (or monitored or detected) by the receiving side (receiver user). Or used). The reservation canceling function can be used when the receiver user cancels a part or all of the program that is to be reserved (or reserved) by the transmission side by a remote control operation or the like.

  Alternatively, a function (see the class of the EPG-related function in FIG. 14A) described in the second part of ARIB STD-B24 (XML-based multimedia coding system) can be used in the script.

  Recording on the receiving side can be regarded as an operation of accumulating the recorded content (one or more programs that have been scheduled recording) in a storage (a hard disk drive, a flash memory, an optical disk, or the like) on the receiving side. Therefore, in the embodiment, the term “recording” covers the case of accumulation as appropriate.

  Arguments (event_ref) of reservation-related functions (isScheduledToTune (), scheduleToTune (), isScheduledToRecord (), scheduleToRecord (), unscheduleToTune (), unscheduleToRecord ()) can have different rules depending on the event transmission method.

  When specifying an event transmitted by the MPEG2-TS system, event_ref must be an object that is interpreted as referring to a resource transmitted by the MPEG2-TS. It is defined as shown below.

  When specifying an event transmitted by the MMT method, the event_ref must be an object interpreted as referring to a resource transmitted by the MMT, and each property thereof is handled as shown in FIG. Stipulated.

  For viewing reservation, recording reservation, reservation cancellation, etc., functions (methods) shown in FIGS. 11A and 11B (a) to (f) can be used.

  The connection state of the receiver to the IP network can be confirmed using, for example, the function (method) in FIG. Further, the receiver can acquire the application object using, for example, the function (method) in FIG.

  In a system that supports (conforms to) the hybrid cast method (for example, the transmission / reception system in FIG. 1), various operations can be performed using a broadcast extension function as shown in FIGS. 14A and 14B. For example, the transmission side (the broadcast station 1000 and / or the service provider 3000 in FIG. 1) uses a HTML document to set a viewing reservation for a receiver (the receiver 5000 in FIG. 1) compliant with the hybrid cast method. Recording reservation, reservation cancellation, etc. can be performed. For this viewing reservation, recording reservation, reservation cancellation, etc., a function (for example, a function of the EPG-related function shown in FIG. 14A) included in a script (JavaScript or the like) embedded in an HTML document can be used.

  FIG. 15 is a diagram exemplifying a correspondence relationship between a receiver mode and a service mode for a data broadcast activated by the receiver. When only BML is used as a data broadcast, it is not assumed that a plurality of BML documents are switched in group units. However, in ARIB-J, a plurality of ARIB-J applications can be transmitted simultaneously, and it is assumed that a viewer (receiver user) switches between them. Therefore, a mechanism is provided that manages the life cycle of the ARIB-J application using the application information table (AIT) and allows the viewer to switch the life cycle by the function of the receiver.

  In a shared receiver that supports both BML and ARIB-J, a BML document is also managed as an application. For the management, ARIB STD-B23 defines a receiver function called an application manager. In the BML / ARIB-J shared receiver, the life cycle of the process presented by the BML document can be controlled by this application manager. Using this application manager, the start control of BML and ARIB-J as illustrated in FIG. 15 can be performed.

  FIG. 16 is a flowchart illustrating an example of a start operation of the data broadcast processing system in the BML / ARIB-J shared receiver. If a data broadcast by ARIB-J has been transmitted, additional_arib_j_info () exists as a data encoding scheme descriptor in the PMT. When trying to activate the data broadcast processing system, the shared receiver searches for a PMT (ST10) and checks whether or not additional_arib_j_info () exists in the PMT (ST12).

  If there is no additional_arib_j_info () (N in ST12), data broadcasting by ARIB-J is not transmitted, so additional_bxml_info () in the PMT is obtained (ST14), and BML is started (ST20).

  If there is additional_arib_j_info () (Y in ST12), reference is made to invocation_priority in additional_arib_j_info (). When the invocation_priority is “0” (ARIB-J has priority), the AIT transmitted by the AIT transmission method is acquired (ST16).

  When invocation_priority is “1” (the setting of the receiver has priority), the setting of the receiver is acquired (ST18). If the receiver setting is "ARIB-J priority", the AIT is acquired (ST16). When the receiver setting is “BML priority”, additional_bxml_info () is acquired (ST14), and BML is started (ST20). When the invocation_priority is “2”, the BML is prioritized, additional_bxml_info () is obtained (ST14), and the BML is started (ST20).

  When the ARIB-J is activated after acquiring the AIT (ST16), the application_control_code in the AIT is referred to (ST22). If the application_control_code is AUTOSTART (Y in ST22), the ARIB-J application is automatically started (ST24). If the application_control_code is not AUTOSTART (PRESENT or the like) (N in ST22), the activation of the ARIB-J application is suspended (ST26), and the AIT is monitored. When the AIT is updated during the monitoring and the application_control_code becomes AUTOSTART, the ARIB-J application is automatically started (ST24). By defining a default ES (for example, 0xA0) in which the ARIB-J application is arranged, such monitoring and other startup sequences can be easily performed.

When the BML is activated (ST20), the AIT (AIT on the communication server) can be obtained from the Internet by referring to the URL of the AIT described in the BML. From the AIT, the above-described permission bitmap (permission_bitmap) can be obtained. (This permission_bitmap can be used, for example, in ST200 of FIG. 25A. Acquisition of the AIT will be described later with reference to FIG. 42.)
FIG. 17 is a diagram exemplifying a correspondence relationship between a broadcast extension function (AIT controlled application cooperation function) and a specifiable name space. Here, regarding the module, the resource, the ES / NPT general-purpose event component, and the namespace on the IP transmission path, "startReceivingAIT () whose argument as a URI description element is ait_uri" and "argument as a URI description element are ait_uri" getReceivedAIT () "and" startAITControlledApp () in which the argument as a URI description element is ait_uri "can be specified. When the return value as the URI description element is Array [] [2], the namespace corresponding to the function “getReceivedAIT ()” is a module, a resource, and a namespace on the IP transmission path.

  FIGS. 18A to 18C exemplify the correspondence between some extended functions (getBrowserSupport ()) and character strings specified in their arguments.

  FIG. 19 is a diagram illustrating how the permission bitmap (permission_bitmap) used in the embodiment is operated. FIGS. 20A and 20B are diagrams exemplifying a relationship between bit values in bitmap 0 and bitmap 1, assignment of functions, and operations. FIG. 21 is a diagram illustrating a data structure of an external application control descriptor that can be used in the embodiment.

  Whether the receiver can execute viewing reservation, recording reservation, reservation cancellation, etc. under the hybrid cast method is determined by, for example, the bit value of permission_bitmap (“O” in “viewing reservation, recording reservation API” indicated by bit 4 in FIG. 20B). (See the mark).

  Whether or not the receiver complies with the hybrid cast scheme can be determined using a specific bit value of the permission_bitmap (for example, bit0 to bit2 in FIG. 20B).

  permission_bitmap is a bitmap for determining an access right, and whether or not access to each broadcast resource can be determined by a 16-bit bitmap for each function. The upper three bits of permission_bitmap indicate the switching of the bitmap, and the assignment of the other function bitmaps can be defined in actual operation.

  If the permission_bitmap determines that the user does not have the access right, the receiver invalidates the access. For example, if the permission_bitmap determines that the user does not have the access right of the hybrid cast method, the receiver can be configured not to access the HTML document including the reservation related function.

  permission_bitmap can be included in the external application control descriptor (see FIG. 21). This external application control descriptor is transmitted in the application information table (AIT) specified in ARIB STD-B24 Vol. 4, 5.1. The AIT including the permission_bitmap (part of information used for controlling the non-broadcast managed application) can be obtained using the function of the AIT controlled application cooperation function (see FIG. 14B).

  FIG. 22 is a diagram exemplifying a bitmap indicating a correspondence between an application class and a bit value. The bitmap indicates the class of the application for which the access authority is set. In this bit map, when a plurality of bits are 1, the range can be set by the OR condition of the range of each class.

  FIG. 23 is a diagram exemplifying a correspondence relationship between a broadcast extension function (IPTV cooperation function) and a specifiable name space. Here, “startDlcDownload () whose argument as a URI description element is src_path” and “startVOD () whose argument as a URI description element is metafile_uri” can be designated as the name space on the IP transmission path.

  FIG. 24 is a flowchart illustrating an example of processing on the transmission side to which the embodiment is applied. The content of this processing can be determined according to the intention of the transmitting side (for example, the broadcasting station 1000 and / or the service provider 3000 in FIG. 1).

  First, when it is desired to make a viewing reservation for one or more programs transmitted by the broadcasting station 1000 (Y in ST100), a reservation script (JavaScript or the like) for each viewing reservation target program is created by using a viewing reservation function (ST102). ). If the reservation can be canceled (Y in ST104), a function for canceling the reservation is described in the script (ST106).

  When it is desired to make a recording (accumulation) reservation for one or more programs transmitted by the broadcasting station 1000 (N in ST100, Y in ST110), a reservation script (JavaScript or the like) for each recording reservation target program using a recording reservation function. Is created (ST112). If the reservation can be canceled (Y in ST114), a function for canceling the reservation is described in the script (ST116).

  When the reservation cancellation function is not described in the script (N in ST104, N in ST114), or when the script is described with the reservation cancellation function (ST106, ST116), if there are two or more created scripts, The description contents are merged in the processing order (ST120). The script after the merge is embedded in the HTML5 document.

  As information for checking whether or not the receiving side complies with the hybrid cast, for example, a function (“startReceivingAIT ()”, “getReceivedAIT ()”, etc. in FIG. 14B) that can be used to acquire an AIT including permission_bitmap can be considered. . If such check information does not exist in the HTML document (N in ST122), the information is added to the HTML document (ST124). After the creation of the HTML document to which the check information has been added, if there is further addition (or modification) of the reservation (N in ST126), the processing of ST100 to ST124 is repeated. If the created HTML document is OK, the processing in FIG. 24 ends (Y in ST126). The HTML document (HTML5 or later document) thus created can be sent to the receiving side via the Internet.

  FIG. 25A and FIG. 25B are flowcharts illustrating an example of processing on the receiving side to which the embodiment is applied. FIG. 26 is a diagram exemplifying an alert screen (a screen of a window overlapping with a currently displayed video) asking the user whether to accept a reservation using a function.

  FIG. 27 is a diagram illustrating a screen display when a recording or viewing reservation is made. FIG. 28 is a diagram exemplifying a case where an alert screen asking the user whether to accept a reservation using a function is displayed in an overlap window on the screen display of FIG.

  FIG. 29 is a diagram illustrating a reservation list when a recording reservation is made. FIG. 30 is a diagram exemplifying an operation screen in which a user on the receiver side confirms reservation contents and cancels a part of the reservation. FIG. 30 is a diagram exemplifying a display screen of an EPG in which a reserved program is marked.

  When the receiving side (for example, one of the receivers 5000 in FIG. 1) receives the HTML document (the document after HTML5) created by the processing in FIG. 24, the processing enters the processing in FIG. 25A. The reservation-related information in the sent HTML document is based on the hybrid cast method. If a reservation-related script in an HTML document is processed by a receiver that does not support hybrid cast, the reservation operation intended by the sender may not be completed. Check (ST200).

This check can be performed, for example, based on whether or not a specific bit in the permission_bitmap included in the AIT corresponds to a bit (ID bit) for identifying a hybrid cast. (If there is information other than permission_bitmap that can indicate hybrid cast compliance in the HTML document, that information may be used for checking.)
If the receiving side does not conform to the hybrid cast (N in ST202), the process returns to another process without processing the script in the received HTML document. If the receiving side complies with the hybrid cast (Y in ST202), it is checked whether or not the script in the HTML document has a function related to reservation (ST204). When there is no function related to the reservation (N in ST204), the process returns to another process without performing any process.

  If the script in the HTML document has one or more functions related to reservation (Y in ST204), the user is inquired whether to make a reservation using one or more functions described in the script (ST206). This inquiry can be made immediately after the determination of ST204 is YES.

  As a method of inquiring whether or not to make a reservation, an overlapping window for "confirmation of reservation" is displayed in a partial area 100a ((a) in FIG. 26) of the screen 100 currently displayed on the user's receiver. A method of generating 200 ((b) of FIG. 26) is conceivable. In the window 200 popped up at the top of the screen 100, for example, "Reservation for viewing (or recording reservation) is entered from a broadcasting station. Do you want to make a reservation?" Please select by key operation and decide. " This display can be configured so that it does not disappear until the user selects and determines “Yes” or “No”.

  Also, as shown in FIG. 27, when a window 300 for making a reservation for recording or viewing is displayed, a reduced screen 400 of the program to be reserved can be displayed as a moving image. HTML5 and later browsers also support moving image display, and thus a screen display (100) including such a reduced screen display (400) of the moving image can be displayed on the browser screen. By being able to display a moving image, for example, when a user makes a reservation, the content can be checked on the reduced screen, and it is possible to determine whether or not the reservation can be made without mistake.

  When such a window 300 or the reduced screen 400 is displayed, the receiver may receive an HTML document (HTML5 or later HTML document) including a reservation function from the transmission side (broadcasting station or server). In this case, as illustrated in FIG. 28, an alert screen for asking the user whether to accept a reservation using a function of the HTML document can be displayed on the current screen display (FIG. 27) in the overlapping window 200. For example, when the user selects and determines a “reservation” button in the window 200 by operating the remote controller, program reservation (recording reservation and / or viewing reservation) based on the reservation function of the HTML document is performed. The reservation at this time can include a program selected by the user for reservation (for example, a broadcast program from 10:00 on October 22 (Sat)).

  Voice guidance for "confirmation of reservation" may be provided together with the output of the overlapping window 200 or instead of outputting the overlapping window 200. For example, a voice guide saying, "You have a reservation from a broadcast station. Do you want to make a reservation? If you want to make a reservation, please say" Reserve "to the TV. , Using the speaker of the receiver 5000. (It is possible to provide a microphone and a voice recognition unit (not shown) in the receiver so as to recognize the user's response to the voice guidance by voice and perform processing corresponding to the content of the response.) It can be configured to repeat at regular intervals until a reply is given. Whether or not to give the voice guidance can be determined by the user's prior setting for the receiver.

  Here, the description returns to FIG. 25A. If the user selects and determines “No” in window 200 (FIG. 26B), or responds by voice with “No reservation” (N in ST208), the process returns to other processes without performing any processing. . If the user selects and decides “Yes” in window 200 or responds by voice with “Reservation” (Y in ST208), a process according to the contents of the reservation is performed.

  That is, when there is one or more recording reservation functions in the script in the HTML document, a reservation list (see FIG. 29) of one or more recording reservation target programs is created using those functions (ST210). Alternatively, an EPG (see mark RRM in FIG. 31) in which one or more programs to be scheduled for recording are marked is created using these functions (ST210).

  When there is one or more viewing reservation functions in the script in the HTML document, the reservation list of one or more viewing reservation target programs (not shown, but the item of “recording destination” is Is created (ST212). Alternatively, an EPG (see mark RWM in FIG. 29) in which one or more viewing reservation target programs are marked is created using those functions (ST212).

  A user who has viewed the recording reservation list (FIG. 29) or the EPG (FIG. 31) marked with recording reservation can cancel the recording reservation of part or all of the reserved program by operating a remote controller or the like. When part or all of the recording reservation is to be canceled (Y1 in ST214), if there is a function for canceling the recording reservation, a user operation screen for canceling the recording reservation for each program on the reservation list (see FIG. 30) ) Is created (ST216). Alternatively, an EPG is created so that the reservation marking can be removed for each program from the EPG (see mark RRM in FIG. 31) on which one or more recording reservation target programs are marked (ST216).

  Similarly, a user who has viewed the viewing reservation list (excluding the item “recording” from FIG. 29) or the EPG (FIG. 31) marked with viewing reservation is able to view a part or all of the reserved program. You can cancel your reservation. When part or all of the viewing reservation is to be canceled (Y2 in ST214), if there is a function of canceling the viewing reservation, a user operation screen (not shown, for canceling the viewing reservation for each program on the reservation list, 29 (corresponding to the item excluding the item of “USB_HDD1”) (ST218). Alternatively, an EPG is created so that the reservation marking can be removed for each program from the EPG (see mark RWM in FIG. 31) on which one or more viewing reservation target programs are marked (ST218).

  When a part or all of one or more programs reserved on the reservation list or the EPG is canceled (Y in ST220), processing of viewing reservation and / or recording reservation after the reservation cancel operation is executed (ST222). ). If none of the one or more programs reserved on the reservation list or the EPG has been canceled (N in ST220), processing of viewing reservation and / or recording reservation without reservation cancellation is executed (ST224). When the above reservation process is completed, the process returns to another process.

  Each of the receivers can be configured so that the user can change the contents of the reservation (including cancellation of all reservations) after the reservation is completed.

  In other words, the function used for performing the above-mentioned reservation viewing, recording, or canceling the reservation may be a function used for displaying the overlapping window, as described above, or The function may include another function used to display the overlapping window. The overlapping window is not necessarily limited to the window, but may be any confirmation display (button) used by the user to indicate whether the user decides to make a reservation or cancel the reservation. What is necessary is just to have a function of inquiring the user of whether or not to perform the recording and storage operations through the interface.

  FIG. 42 is a diagram illustrating an example of a startup sequence of the HTML application. FIG. 42 illustrates a network-based startup sequence SQ1 starting from trigger A and a broadcasting-based startup sequence SQ2 starting from trigger B.

  In starting an application corresponding to the operation specification of ARIB phase 0, SQ1 is used in the start sequence of the application. That is, it always starts from the start (trigger A) of the data broadcast content, and does not directly start the HTML (HTML5 or later version in the embodiment) application. When the application is started, the BML content is first started (sequence SQ1), the AIT on the communication server is acquired by the script described in the content, and thereafter, the HTML application (such as an application using a reservation-related function, etc.) according to the AIT. ).

  In starting the application corresponding to the operation specification of ARIB phase 1, the sequence SQ2 can be used in addition to the sequence SQ1. That is, it is possible to specify whether to start the BML content or directly to start the HTML application based on the priority information of the PMT (program map table) and the priority information of the AIT in the section format transmitted by the data carousel. When directly starting the HTML application, the application is acquired and started according to the information specified in the AIT transmitted by the data carousel.

  The operation of the application startup priority control can be performed in accordance with ARIB TR-B14, Vol. 3, Part 2, “8.5 Starting and Exiting AIT Controlled Application”. In the operation of ARIB phase 1, the value of the start priority (start_priority), which is an extended parameter of the “additional_arib_bxml_info ()” structure described in ARIB STD-B24 Vol. It is configured to operate according to the operation.

-Specification of application identifier in ARIB phase 0 The value given to the service provider from the IPTV forum is used for isdb: orgID specified in the XML format AIT. As this value, “0” is reserved as a special value, and “0” can be interpreted as matching all isdb: orgIDs. This “0” cannot be used in the description of the AIT. isdb: orgID is assigned a value so that the service provider has a unique value for each application.

・ About application profile and version operation in ARIB phase 0
In order to correspond to the phase 0 operation specification defined in ARIB TR-B14 Volume 3, Part 2, Chapter 8, mhp: profile specified in the XML format AIT is “1”, and mhp: versionMajor, mhp: versionMinor and mhp: versionMicro are each fixed at “1”.

Signaling in ARIB phase 0 Signaling is based on, for example, the XML_AIT file on the communication server in FIG. The XML_AIT file on the server has a MIME type of application / X-arib-ait-xml; charset = "UTF-8" and is acquired from the server by http or https. The AIT file has its effect only while the application launched by it is valid.

-Specification of application identifier in ARIB phase 1 The value assigned to the service provider from the IPTV forum is used as the organization_id specified in the section-format AIT transmitted by the data carousel. As this value, “0” is reserved as a special value, and “0” can be interpreted as matching all the organization_ids. This “0” cannot be used in the description of the AIT. On the other hand, application_id is given a value so that the service provider has a unique value for each application.

・ About application profile and version operation in ARIB phase 1
In order to correspond to the ARIB phase 1 operation specification specified in ARIB TR-B14 Volume 3, Part 2, Chapter 8, mhp: profile specified in the XML format AIT is "2", and mhp: versionMajor, mhp : versionMinor and mhp: versionMicro are each “1”. The mhp: profile specified in the section format AIT is “0x0002”, and the mhp: versionMajor, mhp: versionMinor, and mhp: versionMicro are each “0x01”.

-About operation of application_control_code in ARIB phase 1 In the operation of phase 1, in the section format AIT, the value of application_control_code is 0x01 (identification name: AUTOSTART), 0x02 (identification name: PRESENT), 0x04 (identification name: KILL) 0x05 (identifier: PREFETCH) is not used. A receiver that has received an unknown application_control_code ignores the application as not being described in the AIT.

-Regarding the operation of the stochastic operation delay descriptor in ARIB phase 1 In the operation of phase 1, the stochastic operation delay descriptor is not operated in the section type AIT.

-Operation of the cache information descriptor in ARIB Phase 1 In the operation of Phase 1, the cache information description is written as described in ARIB TR-B14 Volume 3, Part 2, "8.3.4.7 Operation of cache information descriptor". Do not operate children. Refer to ARIB TR-B14 Volume 3, Part 2, “8.3.4.7 Operation of cache information descriptor” and “8.4.1.5 Autostart application cache” for the operation of the application cache in the operation of Phase 1.

-Signaling in ARIB phase 1 In the operation of phase 1, both AIT in section format transmitted by the data carousel and XML_AIT obtained from communication can be used. The specific section type AIT transmitted in the data carousel is constantly monitored by the receiver. As a result of the monitoring, if it is detected that the state of the AIT has changed, control such as activation and termination of the AIT controlled application can be performed. Refer to ARIB TR-B14 Volume 3, Part 2, “8.5.2 Starting and ending AIT controlled application based on AIT that is constantly monitored” for the operation related to AIT update.

  The AIT (information that can be used to determine whether or not the receiving side complies with the hybrid cast) including the permission_bitmap described above can be transmitted, for example, from the broadcasting station 1000 of FIG. 1 to the receiver 5000 via a broadcast signal. (Corresponding to SQ2 in FIG. 42). Alternatively, the AIT can be transmitted from the service provider 3000 in FIG. 1 to the receiver 5000 via the Internet (corresponding to SQ1 in FIG. 42). Further, the AIT may be configured to be transmitted to the receiver 5000 via a broadcast signal and to the receiver 5000 via the Internet.

If the reception time of the AIT sent via the broadcast signal is different from the reception time of the AIT sent via the Internet, before the execution of the function in the HTML document related to the AIT (for example, at the time of checking ST200 in FIG. 25A). , The information content of the AIT (latest AIT) whose reception time is later is preferentially adopted. Alternatively, if the priorities of the AIT via the broadcast signal and the AIT via the Internet are determined in advance, the higher priority AIT is adopted regardless of whether the reception time is after or after. it can. (In determining this priority, the value of the start priority (start_priority), which is an extended parameter of the “additional_arib_bxml_info ()” structure described in ARIB STD-B24 Vol. 2 9.3.2, can be referenced.)
FIGS. 32, 33, and 34 show display examples of a program table used when viewing a broadcast program, or performing viewing reservation, viewing reservation cancellation, recording reservation, and recording reservation cancellation.

  The display switching of the program guide can be performed, for example, by operating the cooperation terminal 7000 that cooperates with the terminal cooperation function. A link terminal 7000 includes a button 7001 for displaying a terrestrial digital broadcast program table, a button 7002 for displaying a program table for BS and CS broadcast programs, and a button 7002 for displaying a program table for broadcast (distribution) by IPTV. A button 7003 is provided. Also, a button 7005 for selectively scrolling the screen vertically and horizontally when the program guide is displayed is provided.

  Further, the cooperation terminal 7000 includes a recording reservation button 7006 for a program to be reserved for recording, a viewing reservation button 7007 for a program to be reserved for viewing, a cancel button 7008 for a reserved program for recording, or a reserved program for viewing.

  FIG. 32 shows a state where a program guide for a terrestrial digital broadcast program is displayed on the display 5002. When a program guide for a terrestrial digital broadcast program is displayed, an identification mark 7011 indicating the type of the program guide is displayed on a part of the display 5002. FIG. 33 shows a state where a program guide for BS and CS broadcast programs is displayed on the display 5002. When a program guide for BS and CS broadcast programs is displayed, an identification mark 7012 indicating the type of the program guide is displayed on a part of the display 5002. FIG. 34 shows a state where a program guide for IPTV broadcasting is displayed on the display 5002. When a program guide for IPTV broadcasting is displayed, an identification mark 7013 indicating the type of the program guide is displayed on a part of the display 5002. The identification marks 7011, 7012, and 7013 may have different colors.

  The example of the illustrated program table shows a period in which the program is repeatedly broadcast or repeatedly broadcast at intervals in the IPTV broadcast. This program table is also convenient when there is distribution by video on demand. However, a display format such as a program table for a terrestrial digital broadcast program or a BS and CS broadcast program may be used.

  The program table for the terrestrial digital broadcast program and the program table for the BS and CS broadcast programs are based on the electronic program guide information (EPG information) acquired via the second processing unit 5300, for example, based on the integrated control unit 5200. And stored in memory. This EPG information is automatically updated periodically, for example.

  In addition, EPG information for IPTV is obtained via the first processing device 5100. The first processing device 5100 periodically acquires the program guide of each channel, and for example, in the integrated control unit 5200, combines the program guide of each channel and stores the combined program guide in the memory as the program guide for display.

  The above-described program tables have been described as being independently displayed on the display 5002. However, the present invention is not limited to such a display method, and a plurality of types of program guides may be simultaneously displayed on the display 5002 in an overlapping manner.

  FIG. 35 shows a state where a program table 5031 for terrestrial digital broadcast programs, a program table 3012 for BS and CS broadcast programs, and a program table 3013 for IPTV broadcast are simultaneously displayed on the display device 5002.

  When a plurality of program guides are displayed at the same time, each program guide may be displayed in an overlapping manner. The display area of each program may be divided on the screen. In any of the display modes, each program table can be scrolled vertically or horizontally on the screen when a part thereof is designated by the cursor.

  In each embodiment showing the display example of the above-mentioned program guide, the fact that the viewing reservation and / or the recording reservation has been made can be visually recognized by coloring or adding a mark to the area of the program name. Also, the fact that the recording has been completed can be visually recognized by coloring or marking.

  Also in the case of the embodiment of FIG. 35, a button 7001 for operating a terrestrial digital broadcast program guide provided on the cooperative terminal 7000, a button 7002 for operating a program guide for BS and CS broadcast programs, and an IPTV broadcast ( Using a button 7003 for operating a (distribution) program guide, viewing reservation (or reservation cancellation), recording reservation (or reservation cancellation), and the like can be performed.

  In the program guides shown in FIGS. 32 to 35, the horizontal axis represents time or date and time, and the vertical axis represents channel (broadcasting station), but the horizontal axis represents channel (broadcasting station) and the vertical axis represents time or date and time. May be done.

  FIG. 36 is a diagram showing another example of the communication form between the receiver 5000 and the service provider device 3000 when performing viewing reservation, canceling viewing reservation, recording reservation, and canceling recording reservation.

  The receiver 5000 displays an IPTV broadcast program guide (EPG) based on a user operation (AS1). The user can select and determine, for example, a program to be reserved for recording from the program table by operating the remote controller (AS2, AS3).

  The receiver 5000 accesses the service provider apparatus 3000 of the program using the URL and requests information on the program (AS3). Then, the service provider apparatus 5000 sends the receiver 5000 information (which may be referred to as API information) including a function relating to recording reservation (or information including only information relating to recording reservation) in an HTML5 description document. (ES1).

  The receiver 5000 confirms the transmitted function (AS4), and if the reservation is not possible, displays a message indicating that the reservation is not possible on the display of the receiver 5000 and ends the processing (AS6). When it is determined in the sent function that reservation is possible (AS7), a reservation screen is displayed on the display, and the user selects a reservation button and presses a setting button to end the operation.

  In the receiver 5000, program reservation information of the program is described in a reservation management table. For example, a reservation mark is added to a column of information (including a channel (address), a broadcast start time, a broadcast end time, and the like) of the program in the reservation management table.

  When the broadcast time of the reserved program approaches, the receiver 5000 sets a reception channel of the first processing unit 5100 (AS8). Then, reception of the program is started, and automatic recording is started (AS9, AS10, AS11). At this time, the broadcast of the program by the service provider apparatus 3000 is started (ES2). When the broadcast of the program ends, the service provider apparatus 3000 notifies the receiver of an end function (ES3). Upon receiving the end notification, the receiver 5000 turns off the connection with the service provider apparatus 3000 and ends the scheduled recording (SA12). After the connection is turned off, a message “End scheduled recording” may be displayed. By doing so, the user knows that the connection has been turned off.

  Although the above description is about recording reservations, viewing reservations are made in the same manner as for viewing reservations. However, in the case of viewing reservation, recording is not performed, and the receiver 5000 is controlled to display the reserved program.

  In the case of canceling the viewing reservation or the recording reservation, only the reservation information of the reserved program in the reservation management table is deleted.

  FIG. 37 is a flowchart illustrating the parental lock function / unlock function. Depending on the program, there is a case where a function related to parental is attached to the program information (service information). In such a case, some people, for example, who are 21 years or older, have the authority to release the parental lock. This flowchart is a flowchart for realizing the operation processing function for such a program accompanied by the pan rental lock. This function is also realized by the application in the integrated controller 5200.

  Now, it is assumed that the receiver 5000 has received a certain program, and has received a reproduction instruction from an operation device (remote controller or portable terminal) (step SB1). Then, it is determined whether or not parental lock level information is attached to the related information of the program (step SB2). If the program does not have parental lock level information, the received program is reproduced and displayed (step SB3).

  However, in the case of a program accompanied by parental lock level information, a message such as "The program is locked with pan rental lock" is displayed on the display 5002 (step SB4). Here, when there is a release key input from the operation device (step SB5), it is determined whether or not the release key is correct (step SB6). If the release key is correct, the reproduction and display of the received program is executed (step SB3). If the release key is not correct, it is determined whether or not a predetermined time has elapsed since the reception of the program (step SB7). If the predetermined time has not elapsed, the input of the release key is waited and the predetermined time has elapsed. In this case, the process ends (step SB7), and a message such as "Cannot view" is displayed.

  FIG. 38 is a flowchart for explaining a function that allows a user to set a parental lock function for an arbitrary program. For example, for certain programs, parents may not want to show to children. In such a case, the user can operate the operation device to activate the parental lock function (step SB1). Then, a desired program table is displayed (step SB2). Next, a program for which a parental lock is to be set is selected by a cursor (step SB3). Next, when the enter button is pressed (SB4), an input of an unlock key at the time of viewing is requested (step SB5). Here, if the user inputs the setting of the lock release key (step SB6), the process ends.

  In order to view the program, the person who wants to view must input the unlock key. The input timing of the lock release key at this time is as described in the previous flowchart.

  FIGS. 39 and 40 show an embodiment in which the terminal cooperation function 5500 is effectively used. The terminal cooperation function 5500 can search for a plurality of portable terminals 7000a and 7000b registered as devices, and can perform data communication (for example, emergency communication) with each other.

  Furthermore, the terminal cooperation function 5500 also has the identification information of the home gateway 7100 (HGW) so that it can communicate with the home gateway 7100. That is, the home gateway 7100 (HGW) can be recognized by the terminal cooperation function 5500.

  The HGW 7100 can communicate with the server 7800 via the Internet. As shown in FIG. 40, the HGW 7100 includes a system controller 7102, a device manager 7103, a network interface (hereinafter, network I / F) 7104, a recording manager 7105, and a sensor control table 7106.

  The control data management unit 7101 includes an application manager (hereinafter, APP-Mg), an event manager (hereinafter, EVT-Mg), and a configuration manager (hereinafter, CONFIG-Mg).

  APP-Mg manages a plurality of applications for controlling various operations of the HGW 7100. The EVT-Mg manages an event application or the like for controlling various operations according to occurrence of various events. The EVT-Mg can also control the record manager 7105. The recording manager 7105 can record data or video in the storage medium 5001 via the terminal cooperation function 5500.

  The CONF-Mg recognizes functions in the HGW 7100 and various functions to which the HGW 7100 is related, and manages a configuration application that performs, for example, operation order and operation restriction. The CONF-Mg can perform initial setting of each functional block, restriction of functions, extension of functions, priority order, operation time, and the like. The system controller 7102 can control the sequence of each block in the HGW 7100.

  The HGW 7100 can communicate with the various sensor groups 7200 by wire or wirelessly. The mobile terminal 7000c located outside the home network 7300 can communicate with the HGW 7100 when under the management of the HGW 7100, and can also communicate with the terminal cooperation function 5500 via the HGW 7100. It is. As shown in FIG. 40, the various sensor groups 7200 include a camera 7201, a microphone 7202, a speaker 7203, and the like that can be controlled by EVT-Mg. Note that the camera 7201, the microphone 7202, and the speaker 7203 are installed at a plurality of places in a home.

  Also, the EVT-Mg can determine the detection data from the external sensor taken in from the network I / F 7104 and / or the data from the camera 7201 and the microphone 7203, and control the next action or behavior.

  The device manager 7103 can authenticate other devices operating in association with the HGW 7100 and register them in the memory. Therefore, the device manager 7103 can manage another connected sensor (sensor group 7200) via the network I / F 7104.

  The device manager 7103 also registers identification data of a server (not shown) connected via the Internet, and can recognize it.

  The sensor control table 7106 stores the name of each sensor of the sensor group 7200, position information of each sensor, and data for controlling each sensor. Also, the name and position information of each sensor can be displayed on, for example, the smartphones 7000a and 7000b, so that the user can confirm the type and mounting position of the sensor.

  The network I / F 7104 is connected to other sensors in the home via short-range wireless communication.

  Some high-performance sensors may include a control data management unit. The control data management unit includes an application manager (APP-Mg), an event manager (EVT-Mg), and a configuration manager (CONFIG-Mg) as the HGW 7100 has. The sensing function included in the sensor includes various elements according to the purpose of sensing. The various elements may be, for example, a camera and a microphone as in the case of the HGW 600. Further, various elements include a heat sensor, a temperature sensor, a humidity sensor, an illumination sensor, a pressure sensor, a switch, and the like. A sensor may include one or more sensing elements for its intended use.

  The above-mentioned sensor is a sensor that detects the opening and closing of a door, a sensor that detects sounding of a certain volume of sound, a sensor that detects movement of a person, a sensor that detects opening and closing of windows, It is arranged in various places in.

  In the above-described system, when the HGW 7100 outputs a detection signal from one or more of a camera, a microphone, another sensor,..., The control data management unit 7101 recognizes that an event has occurred. Then, the control data management unit 7101 controls an arbitrary camera 7201 via the record management unit 7105. Accordingly, the camera 7201 sends the monitoring data cached before (for example, 10 minutes before) the event occurrence point to the storage medium 5001 via the record management unit 7105, and continuously transmits the monitoring data for a predetermined time (for example, 3 minutes, (5 minutes, 10 minutes, 20 minutes, 30 minutes, etc.) Continue to send the captured monitoring data. Along with this monitoring data, in the present system, event-related data (may be referred to as event attribute data) when the event is detected is also sent to the storage medium 5001.

  The event-related data may include, for example, any one or more of an event occurrence time, a type of a sensor that detects the event, sensor position data, a recording start time, a recording end time, and the like.

  Here, in the figure, the storage medium 5001 is in a home, but need not necessarily be a home storage medium. The storage location of the monitoring data may be a storage medium in the server 7800 connected via the Internet. The storage medium 5001 includes a data area and a management area. Monitoring data is stored in the data area, and event-related data is stored in the management area.

  The monitoring data may include not only video data but also sound data and measurement data from sensors. The monitoring data may also include, for example, a change in temperature, a change in humidity, or a change in pressure at a specific location.

  In the management area, management data for reproducing the monitoring data is described. This management data also includes the previous event-related data. The management data includes the recording address of the event-related data and the monitoring data corresponding to the event-related data. When a plurality of events have occurred, there are a plurality of event-related data and a plurality of monitoring data corresponding to the plurality of event-related data.

  The event-related data includes a type of an event (which may be referred to as a sensor). In addition, monitoring data (for example, monitoring video) is recorded based on an event, and the event-related data includes a recording start time, a recording end time, and the like.

  In the above system, the terminal cooperation function 5500 can communicate with the HGW 7100. The HGW 7100 can communicate with the server 7800. For this reason, the portable terminal 7000c can access the terminal cooperation function 5500 through the server 7800 and the HGW 7100.

  The flowchart of FIG. 41 shows a simplified operation at the time of full-scale power-on of the receiver 5000. As described above, receiver 5000 includes first processing section 5100 and second processing section 5200. In this embodiment, when the power is turned off immediately before (the spare power supply such as a memory is always on), either the video output of the first processing unit 5100 or the video processing of the second processing unit 5200, or both of them operate. It is provided with a means for storing information on whether or not the user has been there. When the power is turned on next, for example, the integrated control unit 5200 starts up the system that was functioning immediately before the power was turned off.

  For example, when the power is turned on, the integrated control unit 5200 checks the environmental data when the power was turned off immediately before (step SA1). Then, it is determined whether the content being viewed at the time of the last power-off is the broadcast wave signal A processed by the second processing unit 5300 or the distribution signal B according to the hybrid cast specification processed by the first processing unit 5100. (Step SA2).

  If the content that was being viewed when the power was turned off immediately before was the broadcast wave signal A processed by the second processing unit 5300, the second processing unit 5300 is activated. Thus, the video / audio signal from the second processing unit 5300 is supplied to the display 5002 and the speaker system 5003. For a certain period of time, the display 5002 indicates that the source of the displayed content is the second processing unit (or broadcast signal) 5300. Alternatively, an indicator indicating the broadcast signal from the second processing unit 5300 may be lit on the display 5002 (step SA3).

  Conversely, if the content being viewed at the time of the last power-off is the distribution signal B processed by the first processing unit 5100, the first processing unit 5100 is activated. Thus, the video / audio signal from the first processing unit 5100 is supplied to the display 5002 and the speaker system 5003. For a certain period of time, the display 5002 indicates that the source of the displayed content is the first processing unit (or distribution signal) 5100. Alternatively, an indicator indicating the broadcast signal from the first processing unit 5100 may be lit on the display 5002 (step SA4).

  FIG. 43 illustrates an embodiment in which the terminal cooperation function 5500, the recording medium 5001, and the HGW 7100 are effectively used. In this system, a plurality of illuminators 7204, a plurality of speakers 7203, and a plurality of microphones 7201 that can illuminate lights of various colors by combining the emission colors of R (red), G (green), and B (blue) are further controlled. Or a combination thereof is used.

  For example, there is a case where a guardian goes out leaving an infant at home. Parents sometimes want to monitor the infant. In such a case, the guardian can monitor the state of the infant at home using his or her own portable terminal 7000c. If you want to talk to the infant, you can talk through the speaker 7203-1, and if you want to hear the infant's answer, you can listen to the answer from the infant via the microphone 7202-1.

  The above-described system is convenient even if it is installed in a nursery. A guardian who leaves a child at a daycare center and goes to work can check the state of the child who was left outside from outside.

  Furthermore, when the care recipient is at home, the caregiver can use the speaker 7203-1 and the illuminator 7204-1 to communicate his / her intention to the care recipient. For example, for a care receiver who is inconvenient to hear, the color of the illuminator 7204-1 can be variously changed to communicate his / her intention. In addition, the care recipient who is visually impaired can communicate his / her intention through the speaker 7203-1.
