Description

The present invention relates to a receiving apparatus and a receiving method .

  As one of program-linked data broadcast program services in digital broadcasting, a print service using a data broadcast program is being implemented. Print data can be sent through a data broadcasting program to a printer connected to a digital television, and information related to the program content, content that simultaneously refers to program viewing, etc. can be printed in conjunction with the program.

  Broadcast standards and operational rules for digital television related to such printing services are formulated and provided by the Japan Radio Industry Association. The broadcast standard is described in the Japan Radio Industry Association Standard “Data Broadcast Coding Method and Transmission Method in Digital Broadcasting” (ARIB STD-B24 4.4 Edition) (Non-Patent Document 1). Further, the operation rules are described in the technical document “Digital Terrestrial Television Broadcasting Operation Rules” (ARIB TR-B14 2.7 edition) (Non-patent Document 2). Printing services that digital television can implement based on these regulations are classified into the following three forms.

Print mode (1): The digital television acquires print data included in the data broadcast program and requests the printer to print.
Print mode (2): Captures the screen of the data broadcast program being displayed on the digital television and requests the printer to print.
Print mode (3): The digital television designates the content on the Internet indicated by the data broadcast program, and requests the printer to print.

  The print mode (1) is realized by an extended function DOM (Document Object Model) -API (Application Program Interface) defined in Non-Patent Document 1 and Non-Patent Document 2. For example, there are printFile () and printTemplate (). Here, printFile () acquires print data (printFile print data) from a transport stream (TS) obtained by receiving and demodulating a broadcast wave from a digital television, and transfers the print data to a printer to make a print request. is there.

  The print form (2) is realized by printStaticScreen (), which is an extended function DOM-API defined in Non-Patent Document 1 and Non-Patent Document 2.

  The print form (3) is realized by printUri () that is an extended function DOM-API defined in Non-Patent Document 1 and Non-Patent Document 2. printUri () causes the printer to acquire print data (printUri print data) indicated by a URI (Uniform Resource Indicator) specified by the argument, and issues a print request.

When a user uses such a print service, the print service is obtained when the broadcast program is viewed and the print content is obtained and used, and the print content provided by the broadcast program is stored and printed at a later date. There is a way to do it. A method for accumulating print contents and using them at a later date is described in, for example, Japanese Patent Application Laid-Open No. 2005-210408 (Patent Document 1). According to the method disclosed in Patent Document 1, a user can store print content by data broadcasting in association with video data, and the receiver displays the stored video data as options to the user. Thus, the user can print the print content associated with the selected screen display by selecting the print content while referring to the video data. Thereby, when selecting the stored print content, it is possible to recall the contents of the program from the video data and to refer to the print conditions displayed in the program.

With the development of digital broadcast programs that provide such printing services and the improvement of program production technology, the relevance of the contents of print contents and broadcast programs becomes important. In other words, the print content is not simply provided to the user, but the program content and the print content reference are associated with each other and provided as an integrated service.
JP-A-2005-210408 Japan Radio Industry Association Standard "Data Broadcast Coding and Transmission System in Digital Broadcasting" (ARIB STD-B24 4.4 Edition) Japan Radio Industry Association technical document “terrestrial digital television broadcasting operation rules” (ARIB TR-B14 2.7 edition)

  Despite the importance of the correspondence between the contents of the program and the print content as described above, when using the print service of the program accumulated by the user in the past, in order to look for the location that provides the print service, It was necessary to play the program and watch it in order. Therefore, for example, when the target print service is provided near the end of the program, it is necessary to view almost the entire program. Further, the technique of Patent Document 1 associates and saves a captured image of a video screen when a print operation is performed when a user prints a print content, and retrieves the saved print history information later. The captured image is displayed. That is, it cannot be used for grasping the print content corresponding to an arbitrary video section of the recorded video data.

<Example 1>
(Data broadcasting program printing system)
FIG. 1 is a block diagram showing the configuration of the entire system. The digital television 101 receives broadcast radio waves of a program transmitted from the transmission antenna 112 by the broadcast station 111 via the reception antenna 107, and provides the user with a broadcast program based on video and audio and a program-linked data broadcast program. The user operates the digital television 101 through the remote controller 108 to use the program viewing and data broadcasting program print service. The recorder 102 functions as a recording unit that accumulates broadcast programs received by the digital television 101 through the IEEE 1394 interface control unit 104.

  The printing apparatus 103 is a network printer, and is connected to the digital television 101 and the recorder 102 via the network 105 so as to communicate with each other. Each device connected to the network can be connected to the Internet 109 via the broadband router 106, and content data on the WEB server 110 on the Internet can be browsed or downloaded.

(Configuration and operation of digital TV)
FIG. 2 is a block diagram showing the internal configuration and external connection of the digital television 101. The digital TV 101 has a digital TV broadcast channel selection function as a basic TV function. In addition, the digital television 101 has, as an extended function, a standard STD-B24 “Data Broadcast Coding and Transmission System in Digital Broadcasting” by the Radio Industry Association (ARIB)
It has a browsing function and a printing function for data broadcasting programs defined in the above.

(Digital TV channel selection processing function)
First, the channel selection processing function of the digital television 101 will be described. With the channel selection processing function, when the user selects a channel with the remote control 108, the digital television 101 receives a broadcast signal via the antenna 107 and the tuner unit 201, displays video and program information on the video display unit 208, and audio. Is output from the audio output unit 209.

  The internal operation when the digital television 101 performs the channel selection process will be described below.

  The system control unit 211 receives operation information of the remote control 108 by the user via the light receiving unit 212, determines a channel desired by the user, and requests the channel selection control unit 213 to select a channel. The channel selection control unit 213 starts channel selection control by the tuner unit 201 and the data separation unit 202 based on the channel selection request.

  First, the tuner unit 201 performs processing such as demodulation and error correction on the input broadcast signal to form a transport stream (TS). Further, descrambling is performed by descrambling unit 210 and then output to data separation unit 202.

  In the TS, video data, audio data, program information data, data broadcast data, current time information and the like related to a plurality of channels are multiplexed and recorded. The program information includes a program name, a program description, a broadcast channel, broadcast time information (start time and duration), program genre information, and the like. The time information includes year / month / day and hour / minute / second information. The data broadcasting data is repeatedly transmitted from the broadcasting station by the DSM-CC data carousel method defined and described in ISO / IEC13818-6, standard STD-B24 by ARIB, and the like.

  The data separation unit 202 separates video data, audio data, program information data, data broadcast data, and current time information related to the channel desired by the user from the TS. The video data separated by the data separation unit 202 is output to the video decoding unit 203 and subjected to video decoding processing. The audio data is output to the audio decoding unit 204, subjected to decoding processing, and then output to the audio control unit 207. Program information data and data broadcast data are stored in the memory unit 214. The current time information is output to the timer unit 215 via the system bus 222. The timer unit 215 counts time information.

  The video data decoded by the video decoding unit 203 is output to the display control unit 206 via the display synthesis unit 205. The display control unit 206 performs video display by converting the video data into display data and timing suitable for the display resolution, the number of display colors, and the refresh rate of the video display unit 208. The display synthesis unit 205 synthesizes the video data decoded by the video decoding unit 203 and the graphic data generated by the graphic generation unit 218. The voice control unit 207 changes the volume level of the voice data.

  When the above-described channel selection processing operation is normally completed, the channel selection control unit 213 stores the selected channel information in the memory unit 214.

FIG. 3 shows details of the remote control 108. The remote control has power selection keys 301, 1 to 12, a channel selection key 302, a channel up / down key 303, and a volume up / down key 304. A program guide key 305 and a data broadcast program key 306 are provided, and a program guide service (EPG) and a data broadcast service can be activated, respectively. During the execution of these services, the user can move the cursor displayed on the screen using the direction keys 307 to 310 and select the service contents using the enter key 311. Also, color keys 312 to 315
It is possible to start a service defined in each scene. When the user operates these remote control keys, the operation content is transmitted to the system control unit 211 through the light receiving unit 212 of the digital television 101 by an infrared signal.

(Digital TV data broadcast program browsing function)
Next, a browsing function and a printing function for data broadcasting of the digital television 101 will be described.
The data broadcast browsing function is a function for displaying data broadcast data repeatedly sent from a broadcasting station by the data carousel method on the video display unit 208 and a function for outputting audio from the audio output unit 209.

  4A to 4C show an example of data broadcast data used in this embodiment. Note that FIGS. 4A to 4C are a single document, and are only divided into three for convenience of display. The data broadcast data includes text information, display layout information, script information, still image information, audio information, and the like. The text information is file data described by BML (Broadcast Markup Language). BML is a page description language for data broadcasting based on XML (extensible Markup Language) defined by the standard STD-B24 of ARIB. CSS (cascading style sheet) is used for display layout information, and EcmaScript is used for script information. Further, DOM (Document Object Model) is used as means for accessing and manipulating the logical structure of BML information and information.

  This BML has a <title> element (FIG. 4A, 7th line) indicating the name of the document in the portion surrounded by the </ head> tag in FIG. 4B, the last line from <head> in FIG. 4A, 6th line. ) And a <script> element (FIG. 4A, 11th line) indicating the definition of the script. Furthermore, in a <body> element (FIG. 4C, the first line to the last line) indicating the text, an <object> element indicating an image, video, and sound, a <div> element indicating an area on the screen, and a sentence The <p> element shown is included. Each element describes a CSS style attribute, and the coordinates, size, color, etc. for display are set.

  FIG. 5 shows a display screen when the BML data shown in FIGS. 4A to 4C is displayed on the video display unit 208 of the digital television 101.

  Next, an internal operation for performing such data broadcast browsing in the digital television 101 will be described. In FIG. 2, the system control unit 211 receives operation information of the remote control 108 by the user via the light receiving unit 212. If it is determined that the request is a data broadcast browse request based on the operation information, the data broadcast control unit 216 is requested to start the data broadcast browse process. The data broadcast control unit 216 acquires the data broadcast data stored in the memory unit 214. When data necessary for browsing is not accumulated, the data broadcast control unit 216 requests the data separation unit 202 to acquire data broadcast data. The data broadcast control unit 216 sends the acquired data broadcast data to the data broadcast browse control unit 217 and requests a browse process.

  When the data broadcast browse control unit 217 obtains an image or the like associated with the BML data, the data broadcast browse control unit 217 executes the script function described in the <load> tag's Onload attribute (FIG. 4C, first line) as an initial script. Here, the start () function is the initial script.

4B, in the start () function described in the 26th and subsequent lines, first, a function for inquiring whether the digital television 101 has a printing function is called. The data broadcast browse control unit 217 has an extended DOM-API called getBrowserSupport () as a built-in API. This API has ““ ARIB ”,“ APIGroup ”,“ Print. When the character string “Basic” ”is received, the value“ 1 ”or“ 0 ”is returned.

  The return value “1” indicates that the print function is provided, and “0” indicates that the print function is not provided. Since the digital television 101 of this embodiment has a printing function, the return value of this API is “1”. In the start () function, next, it is determined whether to draw a button image or text information in the background area 401 of FIG. 5 according to the return value of getBrowserSupport ().

  In this embodiment, since the return value is “1”, the data broadcast browse control unit 217 draws a button image and text information via the graphic generation unit 218 and the display synthesis unit 205. Simultaneously with the operation, the display composition unit 205 performs composition processing with the moving image from the video decoding unit 203.

  In FIG. 5, a moving image decoded by the video decoding unit 203 is displayed in the moving image display area 406. In the text display area 405 on the right side, text indicating the contents of the data broadcast is displayed as text. Here, it is described that print content can be printed as a data broadcasting service. A print button 403 for activating the print service is displayed at the bottom center of the screen, and a previous page button 402 and a next page button 404 for transitioning the display to another data broadcasting page are displayed at the bottom left and right of the screen. ing.

  While the screen of FIG. 5 is being displayed, the user operates the left and right buttons 307 and 309 on the remote controller to move the cursor 407 and decides at a desired position (one of the previous page button 402, print button 403, and next page button 404). Press the key. By this operation, the operation defined for each button is activated. For example, the printing process can be activated by pressing a determination key on the remote controller with the cursor 407 placed on the print button 403.

(User request processing for data broadcasting display)
While displaying the screen shown in FIG. 5, the data broadcast browse control unit 217 stands by until there is any request by a user operation. When there is a user request, a request content determination process is performed, and a transition is made to a process according to the determination result. That is, when the cursor movement request is made, the cursor movement process is executed. If it is a screen transition request, screen transition processing is executed. If the request is a print request, the processing branches depending on whether it has a print function, that is, the API return value of getBrowserSupport () described above. If the user does not have a print function, the process returns to the user request reception waiting process. If it has a print function, the following print request process is executed.

  If the print according to the user request is a print designating print data in the data broadcast data, push-type direct printing is performed by a printFile () function that is an embedded API. Push type direct printing is a printing method in which print data received as data broadcast data is transferred to a network printer via a network and printed.

FIG. 6 shows an operation flow and communication between the digital television 101 and the network printer 103 by push direct printing. When the printFile () function is activated, the print control unit 219 outputs a print job request control signal directly to the network printer 103 via the communication control unit 220 (S601). The network printer 103 is in a standby state until there is a JOB request (S621), and if print acceptance is possible when the request is received, a printable response is returned (S622). The print control unit 219 is in a standby state until a response is received (S602). When the response is received, the print data designated by the printFile () function is read from the memory unit 214, and the print data is transmitted to the network printer 103 through the communication control unit 220 (S603). When the network printer 103 receives the print data (S623), the network printer 103 performs a parsing process, a layout process, and a rendering process (S624), and executes printing by a printer engine process (S625). When all the received data is printed, the process is terminated (S626).

  On the other hand, when the print according to the user request is print specifying print data on the Internet, pull-type indirect printing is performed using the printUri () function that is an embedded API. Pull-type indirect printing is a method in which the network printer 103 receives print data from the WWW server 110 on the Internet and performs printing based on the URI received as data broadcast data.

  FIG. 7 shows the operation flow and communication of the digital television 101, network printer 103, and WWW server 110 by pull-type indirect printing. When the print control unit 219 specifies URI information and the printUri () function is activated, the print control unit 219 issues a JOB request to the network printer 103 through the communication control unit 220 (S701). The network printer 103 waits for a JOB request (S721), and returns a printable response if printing can be accepted when the request is received (S722). The processing on the print control unit 219 side ends when the response is confirmed (S702). The network printer 103 accesses the WWW server 110 based on the received URI and requests print data (S723). Subsequently, the network printer 103 receives print data sent from the WWW server 110 (S724), performs data parsing processing, layout processing, and rendering processing (S725), and executes printing by printer engine processing (S726). If all the data has been printed, the process is terminated (S727).

  Note that the user rarely explicitly indicates push type direct printing or pull type indirect printing, and in general, printing is automatically performed in response to an operation of pressing a print button displayed on the browser. Done. The above-described printFile () function and printUri () function are referred to as print execution functions.

(Program related information printing service by program linked data broadcast program)
FIG. 8 schematically shows a broadcast program data configuration of a digital broadcast television program accompanied by a data broadcast including a program related information print service. The program 1 shown in the figure provides a broadcast program based on video and audio and a print service based on data broadcast in the same manner as the data broadcast program described with reference to FIGS.

  As shown in the figure, in the program 1, the video stream and the audio stream are broadcast in time as PES (Packetized Elementary Stream). In addition, the section data of the data broadcast data is repeatedly broadcast for each period by the data carousel method. A plurality of data constituting one set of data broadcast data at a certain time is collected in module 1, module 2, or module 3 in a MIME (Multipurpose Internet Mail Extensions) format. That is, one unit of the module corresponds to the data broadcast data, and in this program 1, three data broadcast data are transmitted by broadcasting as the program progresses. Of course, if there is only one type of data broadcast per program, there will be one data broadcast module corresponding to this program.

Module 1 includes BML1 that defines the contents of the data broadcast program provided at 14:00, which is the start time of the program. Furthermore, image data PNG1 and PNG2 for performing screen transition button display on other data broadcast screens, and BML4 and BML5 that define two screens that are transitioned by GUI screen transition operations are included.

  Module 2 includes BML2, BML6, and BML7 that define the contents of the data broadcast program provided between 15:00 and 16:00. Furthermore, image data PNG1 and PNG2 of the screen transition button, image data PNG3 for displaying the start button of the print service, and XHTML2 which is the print content are included. A print document 21 is obtained by printing this XHTML2 with a printing apparatus.

  Here, the print service activated by the print button displayed by PNG3 in BML2 is a push-type direct printing of XHTML2, which is the print content. Similarly, the print service activated in BML6 is pull-type indirect printing using print contents on the Internet, and it is assumed that the reference URI 2 for the print contents activated in BML6 is designated. A print document 22 is obtained by acquiring the print content referred to by the URI 2 and printing it with the printing apparatus.

  Module 3 includes BML3, BML8, and BML9 that define the contents of the data broadcast program provided between 16:00 and 16:30. Further, image data PNG1, PNG2, and PNG3 for performing screen transition and print service activation button display, and print content XHTML3 provided by push direct printing are included. In BML3, the print content of the print service activated by the print button displayed by PNG3 is specified in XHTML3. The print document 3 is obtained by printing the XHTML 3 with a printing apparatus.

  In the program 1, as described with reference to FIG. 8, the module 1, the module 2 and the module 3 of the data broadcast data are broadcast in sequence as the program progresses. Since the presence of XHTML2, URI2, and XHTML3 corresponding to the print content is detected from BML2, BML6, and BML3 included in these modules, the print content is transferred to the recorder three times and stored. The URI corresponds to information for specifying and acquiring the print content, and is different from the actual content of the print content such as the XHTML file. However, in the present invention, the URI for specifying and acquiring the print content is used. Is also described as print content. This is because recording the URI for specifying the print content is equivalent to recording the actual file of the print content.

  Modules in the data broadcasting program are transmitted by a DSM-CC (Digital Storage Media Command and Control) method. In the DSM-CC system, a DII (Download Information Indicator) including module specific information is transmitted in addition to a DDB (Download Data Block) that stores a data body. Module specific information includes information assigned to each module, such as module identification information and module version information. The change in the module of the received data broadcast data can be detected by monitoring the change in the identification information of the DII module and / or the version information of the module by the data broadcast control unit 216 through the data separation unit 202.

(Storage of digital broadcast programs for data broadcasting printing services)
FIG. 9 is a flowchart showing a control operation executed by the system control unit 211 of the digital television 101 when recording a digital broadcast program accompanied by a program-linked data broadcast for performing the print service described in FIG.

In FIG. 9, the system control unit 211 receives a user operation input for recording a program (S901), and starts storing video data of the program specified by the user operation and data broadcast data corresponding to the video data (S902). ). Note that in normal program recording, audio data is generally recorded together with video data, but only video data is described here for the sake of simplicity. Of course, the invention does not exclude an apparatus or method for recording audio data together with video data. In the accumulation of video data and data broadcast data, first, the video data and data broadcast data of the broadcast program separated by the data separation unit in FIG. 2 are converted into TS for accumulation. Subsequently, the converted TS is transmitted to the recorder 102 through the IEEE 1394 interface control unit 104 and stored.

  During recording of the video data and data broadcast data of the program, the system control unit 211 monitors the module of the stored data broadcast data (S903). The system control unit 211 always checks the unique information of the module in order to detect whether or not the module has been changed to a new module. When a new module is detected (S904), the system control unit 211 acquires time information indicating the elapsed time from the broadcast start of the program from the timer unit 215 (S905). The time information indicating the elapsed time indicates at which point in the program the module has changed, and as a result, it can be used to specify the section video corresponding to each module in the video data to be recorded. .

  Then, the system control unit 211 associates the reference information for specifying the video data of the program with the time information indicating the acquired elapsed time, and stores them in the print content management table, which is management information (S906). Although the print content management table is described as being present in a storage unit (not shown) of the recorder 102, the print content management table may be stored in the memory unit 214 in the digital television 101.

  Subsequently, the system control unit 211 analyzes the new module detected in step 904 (S907). Then, it is determined whether or not the BML data included in this module includes a data broadcast print execution function (S908). That is, step S908 determines whether there is print content corresponding to the detected module. If it is determined in step S908 that the data broadcast print execution function exists, information for specifying the print content is stored in association with the time information stored in the print content management table (S909). The information for specifying the print content includes unique identification information typified by the file name of the print content and the file storage path (URI) recorded in the recorder 102 as part of the data broadcast data. Is preferred. In this embodiment, the file name is information for specifying the print content.

  In this embodiment, even when the detected module does not contain print content, information is recorded in the print content management table in step S906. However, when print content is not included, it is not always necessary to record information in the print content management table. One feature of the present invention is that when a module including print content is detected, the print content is managed in association with an elapsed time corresponding to the detection timing of the module. In the present embodiment, the time elapsed from the start of broadcasting the stored program is used as time information for specifying the timing at which a new module is detected. However, the present invention is not limited to this, and the actual time at the time of detection is detected. Information may be used.

  FIG. 10 schematically shows the configuration of the print content management table. The print content management table manages various types of information described above for each module of data broadcast data of a recorded program. That is, in association with reference information (for example, a program title) for specifying a recorded program, elapsed time information of a data broadcasting module related to each program and information for specifying a print content included in the module. Remember. If there is necessary information other than the information listed here, it can be stored in the print content management table.

(Print content list display)
Next, display of a print content list capable of displaying a list of print contents associated with a digital broadcast program stored in the recorder 102 will be described. FIG. 11 is a flowchart when the system control unit 211 executes display of a print content list, and a print instruction or video reproduction using the displayed print content list.

  The flowchart of FIG. 11 is started when a list display of print contents included in a data broadcast related to a program recorded by a user operation is instructed. The system control unit 211 first refers to the print content management table (S921), displays a print content list (S922), and waits for a user operation. If the user performs an end operation without selecting a print content in step S923 (S924), the process ends.

FIG. 12 is a screen display example of the print content list 841. In the figure, three icons 842, 843, 844 indicating the accumulated print contents are displayed. Each of these icons is displayed in association with each print content. That is, this icon is linked to information for specifying the print content stored in the print content management table. Further, program information relating to a program corresponding to each print content is displayed as character information. The displayed program information is information acquired and stored from SI (Service Information) included in the broadcast wave when a program is recorded in the recorder 102.
The SI includes information such as broadcast date and time, broadcast channel, program description, performers, etc. in addition to information such as the program title. In the example shown in FIG. 12, broadcast date information, broadcast channel information, and program title information are displayed. Further, data broadcast time information indicating the time when the module including the corresponding print content was broadcast and information indicating the acquisition source (source) of the print content are also displayed.

  The cursor display 846 moves up and down when the user operates the up and down direction buttons 308 and 310 of the remote controller. Note that a scroll bar 845 indicates that print content that can be selected also exists on the icon 842 or below the icon 844. When selecting those invisible icons, the cursor may be moved so that the entire list scrolls. The user can select a print content by placing a cursor on an icon indicating the target print content and pressing the enter button 311 on the remote control.

  When the user inputs an operation to select one of the print contents listed in the displayed print content list (S923), the system control unit 211 displays the selection screen shown in FIG. 13 (S925) and further waits. . The content of the selection screen is for the user to specify whether the selected print content is to be printed immediately or whether a video scene (section video) corresponding to a module including the print content is to be played.

  FIG. 13 is a screen display example of the selection screen. The selection screen 851 is displayed so as to overlap the print content list 841. In addition, a button 852 for instructing printing of the selected print content and a button 853 for instructing playback of the section video at the timing when the module including the selected print content is broadcast are provided. A cursor display 854 for displaying user selection candidates is also displayed. The cursor display 854 moves left and right by operating the left and right direction buttons 307 and 309 of the remote control. The user can input a selection instruction by placing the cursor on the button indicating the desired action among the buttons 852 and 853 and pressing the enter button 311 on the remote control.

When the user selects printing (S926), the system control unit 211 specifies the print content linked to the icon using the information for specifying the print content managed in the print content management table (step S926). S927). Then, from the specified print content information, print content print processing is executed using the print content (XHTML file or URI) included in the data broadcast data stored in the recorder 102 (S928). The print content printing process can be realized by transmitting the acquired print content information to the network printer 103. Details of the printing process are described in the literature presented as non-patent literature, and thus the description thereof is omitted.

  On the other hand, when the user selects the playback of the segment video, the system control unit 211 specifies the print content linked to the icon from the information managed in the print content management table (S929). Then, the information for specifying the program associated with the print content selected by the user and the elapsed time information of the data broadcast module provided with the print content are acquired (S930), and the elapsed time is handled. Video playback is started from the video scene (S931). A method for starting playback from a specific scene of a recorded video is well-known in the technical field of playback of recorded video, and a description thereof will be omitted.

  In playback of a recorded program, the system control unit 211 operates in the same manner as during viewing of a received program. That is, when an operation such as activation of data broadcasting is performed by the user, the system control unit 211 executes activation of data broadcasting for the digital broadcast program being reproduced or operation for the data broadcast program. Therefore, after the start of the playback of the segment video according to the user's instruction, when the print instruction of the print content included in the module corresponding to the segment video is performed by the user's operation (Yes in S932), the corresponding print content The printing process is executed (S933). Further, when the end of program reproduction is instructed by a user operation (S934) or when the recorded broadcast program is reproduced to the end (S935), the process is terminated.

(Configuration examples with different program data distribution methods)
In the above description of the embodiment, the description has been made on the assumption that the distribution of the program data is performed by broadcasting. However, the present invention is not limited to this, and can be applied to a program distributed by communication. For example, when a digital broadcast TS signal is distributed over a communication network, the same operation as in this embodiment can be performed and the same effect can be obtained by using a reception unit for the communication network instead of the tuner unit 201. .

  Also, the control as in this practical example can be performed for a broadcast service of a video on demand (VOD) system in a cable television and a program accompanied by a print service in a VOD service in a communication network. That is, the analysis adapted to the program data is performed, the print content is acquired, and the print content management table is held together with information indicating a specific portion in the program for which the print service is performed. As a result, the same operation as in this embodiment can be performed, and the same effect can be obtained.

(Examples of different configurations of broadcast receivers)
In the description of the above embodiment, as shown in FIGS. 1 and 2, the digital television is provided with a tuner and a display unit, and communicates with an external recorder to store contents. However, the present invention is not limited to this. It is not something. For example, a broadcast receiving device including a tuner and a storage device can execute the above control. In addition, if the recorder is capable of receiving broadcasts and has a function corresponding to the system control unit, the above-described control can be executed by the recorder alone.

<Example 2>
The present embodiment provides a user interface different from that of the first embodiment in the reproduction of a digital broadcast program accompanied by a program-linked data broadcast for performing a print service stored in the recorder 102. Hereinafter, the same parts as those in Example 1 are denoted by the same reference numerals and the description thereof is omitted.
Only differences from the first embodiment will be described.

  FIG. 14 is a flowchart showing a control operation executed by the system control unit 211 when a data broadcast program is reproduced. Hereinafter, the reproduction of a digital broadcast program accompanied by a program-linked data broadcast for performing a print service stored in the recorder 102 will be described using this.

  As a premise, it is assumed that a digital broadcast program accompanied by a program-linked data broadcast for performing a print service is accumulated, and data broadcast data including print content and a print content management table are stored. In this flowchart, the system control unit 211 displays a recorded program list recorded. At the same time, after an arbitrary recorded program is selected from the recorded program list, a user interface capable of instructing to print a print content corresponding to the recorded program or to reproduce a section video is displayed. The system control unit 211 first refers to a print content management table that refers to a recorded program management table (not shown). This recorded program management table is a table for managing information associated with a program such as the program title, broadcast date and time, broadcast channel, and program content of the program recorded on the recorder 102. A recorded program list is displayed using the recorded program information managed in the recorded program management table (S941). The recorded program list is a screen for displaying a list of programs recorded on the recorder 102. In the present invention, since the recorded program list may have any form, illustration and description thereof are omitted.

  The user designates a desired recorded program from the displayed recorded program list and performs a selection act. When a recorded program is selected, a detailed screen of the recorded program illustrated in FIG. 15 is displayed (S942). The detailed screen of the recorded program is generated by the system control unit 211 using the information in the print content management table and the information in the recorded program management table. At that time, the system control unit 211 specifies the information of the recorded program selected by the user in the recorded program management table and uses the recorded program information to inquire the print content management table to obtain the information of the print content management table. obtain.

  FIG. 15 is a display example of the recorded program detail screen, which is displayed on the video display unit 208. The recorded program detail screen displays a program related information display area 862 including the date and time, channel, program title, etc., of the program selected by the user, and a data broadcast configuration display area 863 corresponding to this program. The data broadcasting configuration corresponds to each module constituting the data broadcasting. In the configuration display area 863, the section divided by the update of the data broadcast data, that is, the change of the module is displayed in the time axis direction, and one section corresponds to one module. In the program illustrated in the figure, it can be seen that the data broadcast data is updated at the start of the program at 14:00, 15:00, and 16:00. In other words, the data broadcast corresponding to this program is composed of modules from 14:00 to 15:00 (864), 15: 0 to 16:00 (865), and 16: 0 to 16:30 (866). Yes. Then, the program from 14:00 to 16:30 is divided into three section videos. The display of such a time transition is generated based on the elapsed time information recorded in the print content management table. Here, the time displayed as 14:00 or the like only represents the time at the time when the program was broadcast. Instead of this, the program start time may be described as, for example, 0:00, and time display may be performed based on the elapsed time.

  When there is print content included in each module, the presence of the print content is displayed by an icon 867. Here, the globe mark attached to the icon 867 indicates content on the Internet.

Returning to the flowchart of FIG. When a normal playback instruction for a program is input to the recorded program details screen by a user operation (corresponding to the case where normal playback is instructed in S943), the system control unit 211 refers to the recorded program management table. (S944). The recorded program is reproduced from the beginning of the video data (S945). Normal playback means playback from the beginning of the video data of the program. The program normal playback instruction is executed when the user selects a playback button (not shown) displayed on the recorded program detail screen with the remote controller and performs a determination operation.

  Since the steps S946 to S949 are the same as the steps S932 to S935 in the flowchart shown in FIG. Needless to say, an operation for instructing printing cannot be performed while a video in a section corresponding to a module having no print content is being reproduced.

  When an instruction to reproduce the section video is input to the recorded program detail screen by the user's operation (corresponding to the instruction to reproduce the section video in S943), the system control unit 211 refers to the print content management table ( S950). Subsequent steps S951 and S952 execute the same processing as steps S930 and S931 shown in FIG.

  FIG. 16 shows a detailed screen of the recorded program when the reproduction of the section video is instructed in step S943. A cursor 869 indicates a state where a module corresponding to 15:00 to 16:00 is selected. As a result, this is equivalent to a state in which the user selects a section video from 15:00 to 16:00. In this state, when the user presses the enter button 311 on the remote controller, the system control unit 211 is instructed to play back the section video from the first hour after the program starts. . Of course, it is possible to select a module corresponding to another adjacent segment video and instruct reproduction by a user's remote control operation.

  Returning to the flowchart of FIG. When a print instruction specifying a print content is input to the recorded program details screen by a user operation (corresponding to the case where printing is instructed in S943), the system control unit 211 refers to the print content management table. Subsequent steps S953 and S954 execute the same processing as steps S927 and S928 shown in FIG.

  FIG. 17 shows a detailed screen of a recorded program when printing of print contents is instructed in step S943. A cursor 870 indicates a state in which a print content included in a module corresponding to 15:00 to 16:00 is selected. In this state, when the user presses the enter button 311 on the remote controller, an instruction is issued to the system control unit 211 to execute printing of the print content. Of course, it is possible to select another print content and instruct printing by a user's remote control operation.

  In the recorded program details screen, the print content designation state shown in FIG. 17, the section video selection state shown in FIG. 16, and the print content and section video selection state shown in FIG. This switching can be realized by a method that is easy for the user to operate. For example, these screens may be configured to be freely transitionable by pressing the up and down buttons 308 and 310 of the remote controller.

    According to the present embodiment, in addition to the contents of the program, the user can easily check the status of the section video of the program and the print content included in the data broadcast, and playback of the section video desired by the user with a simple operation, Printing of print contents can be easily executed.

<Example 3>
In this embodiment, data broadcast data is analyzed by a method different from those in the first and second embodiments when a digital broadcast program is recorded. Hereinafter, the same parts as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Only parts different from the first embodiment will be described.

  FIG. 18 schematically shows the data structure of a digital broadcast television program that accompanies a data broadcast including a program related information print service. As shown in FIG. 8, program 1 in the figure provides a broadcast program based on video and audio and a print service based on data broadcast. The configuration of the data broadcast (module 1) distributed at the beginning of the program is different from the first embodiment. Further, the point that the event message 881 is transmitted after the program starts is different from the first embodiment. The event message is a command that the broadcast station multiplexes and transmits to the broadcast data, and is used for performing an operation (event) such as switching of a data broadcast screen under the initiative of the broadcast station. For example, it is used when a data broadcast screen is automatically displayed without any operation by a user during viewing of a digital broadcast. The event message can be operated at a specified time after the event message is received, as well as being immediately operated at the timing when the receiver receives the event message. In the present embodiment, description is made on the assumption that drawing of a data broadcast screen designated by execution of a display instruction by an event message is executed.

  FIG. 19 shows the BML 10 used in the module 1. The BML 10 is described so as to display a video image of a television program on the entire screen using a BML browser for data broadcasting. In addition, the BML 11 shown in FIGS. 20A and 20B describes data broadcast data for providing the print document 4 service.

  Here, the program information included in the TS of the program 1 is designated to execute a data broadcasting service according to the BML 10 at the start of program viewing. In other words, the television program video is displayed on the entire screen according to the description of BML10 between 14:00 and 14:10.

  Then, an event message 881 is sent out at time 14:10. The system control unit 211 detects whether or not an instruction to display a predetermined data broadcast screen based on the received event message has been executed. The display instruction given by the event message 881 is an instruction for displaying a data broadcast screen using a predetermined BML included in the data broadcast data. When the display instruction by the event message is executed, the data broadcast browse control unit 217 draws the BML instructed to be displayed. In this embodiment, it is assumed that the BML 11 is instructed by the event message 881.

  FIG. 21 is a flowchart showing a control operation executed by the system control unit 211 when recording a digital broadcast program accompanied by a program-linked data broadcast for performing the print service described in FIG. In addition, since the process similar to Example 1 is performed in the step which attached the same step number as the flowchart of FIG. 9, detailed description is abbreviate | omitted here.

  In FIG. 21, the system control unit 211 receives a user operation input for recording a program (S901), and records video data and data broadcast data of the program in the recorder 102 (S902). Further, during the recording of these data, it is monitored whether or not the module is changed to a new module (S903). Further, in the present embodiment, the system control unit 211 detects whether or not an event message is included in the TS and an instruction to display a predetermined data broadcast screen based on the event message is executed (S911).

When the execution of the display instruction by the event message is detected, the system control unit 211 acquires the elapsed time (S905). Subsequently, the system control unit 211 stores the reference information of the video data and the elapsed time in association with each other in the print content management table (S906), and analyzes the data broadcast data (S907). This elapsed time is the time (or time) at the time when the display instruction of the event message is executed. In order to specify video data in the same time zone as the data broadcast screen displayed by this event message, that is, the section video Used.

  Subsequently, the system control unit 211 determines whether the BML 11 included in the analyzed data broadcast data includes a data broadcast print execution function, that is, the presence or absence of print content corresponding to the data broadcast data (S908). If it is determined that the data broadcast print execution function exists, information for specifying the print content is stored in association with the time information stored in the print content management table (S909).

  Even if the event message is not detected in step S911, if a new module of the data broadcast data is detected (S904), the processing of steps S905 to S910 is performed.

  FIG. 22 shows a print content management table created by the above processing. According to the figure, the part from the start of program 1 corresponding to module 1 of the present embodiment to 01: 00: 00: 00 is managed as two section videos with a break of 00:00:00 from which the event message was sent. It is shown that. In addition, it can be seen that the printing service by XHTML1 is performed in the section video from 00:10:00 to 01: 00: 00: 00.

  FIG. 23 shows an example of a detailed screen of a recorded program in the third embodiment. The detail screen of the recorded program is generated by the system control unit 211 based on the information in the print content management table shown in FIG. Here, the cursor 891 indicates a state in which a section video 892 of 14:10 to 15:00 where print content exists is selected. In this state, when the user presses the determination button 311 on the remote controller, an instruction is issued to the system control unit 211 to play back the section video from 10 minutes after the program starts. Become. In addition, the user can select an adjacent section video by operating the left and right buttons 307 and 309 of the remote controller.

  In the present embodiment, the print content management table can be created in consideration of not only the timing when the data broadcast data module becomes new, but also the change of the data broadcast service content by the event message. As a result, in the relationship between the contents of the program and the provision of the print service, it is possible to perform more advanced cooperation using the event message.
