Description

  The present invention relates to a recording / reproducing apparatus and a recording / reproducing method for receiving a digital broadcast and recording program content and reproducing the recorded program content. The present invention also relates to a program for operating a computer as such a recording / reproducing apparatus, and a computer-readable recording medium on which such a program is recorded.

  With the spread of digital broadcasting, data broadcasting that multiplexes and broadcasts various contents together with program contents into an MPEG-2 stream is widely used. BML (Broadcast Markup Language) has been established by ARIB (Radio Industry Association) as a language for describing multimedia content for data broadcasting (hereinafter also referred to as “BML content”). Many receivers (such as television receivers and recorders) in circulation have been installed with BML browsers.

  The data broadcast content is repeatedly broadcast by the data carousel method while the corresponding program content is being broadcast. A receiver such as a television receiver or a recorder device accumulates the data broadcast content and plays back the corresponding program content by using an instruction from the user (for example, pressing the d button on the remote control) as a trigger. It is configured to play data broadcast content.

  Patent Documents 1 and 2 disclose a technique for facilitating selection of program content by preferentially presenting program content that meets the user's preference based on keywords or the like included in program information included in data broadcasting. Has been. Patent Document 3 discloses a technique for searching the Internet based on not only program information included in data broadcasting but also program information and presenting the obtained program related information to the user.

[Configuration of recording / reproducing apparatus]
The configuration of the recording / reproducing apparatus 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a configuration of the recording / reproducing apparatus 1.

  As shown in FIG. 1, the recording / reproducing apparatus 1 includes a receiving unit 10, a program-independent content extracting unit 11, a program-independent content recording unit 12, a program-dependent content extracting unit 13, and a program-dependent content recording unit 14. A program content recording unit 15, a content storage unit 16, a program-independent content reading / playing unit 17, a program-dependent content reading / playing unit 18, a program content reading / playing unit 19, and a content drawing unit 20. For example, it is connected to the display terminal 2.

  The receiving unit 10 receives a broadcast wave of digital broadcasting and demodulates a data stream (for example, an MPEG-2 stream) from the broadcast wave. The data stream demodulated by the receiving unit 10 is encoded data representing program content, and data broadcast content corresponding to the program content is multiplexed. The receiving unit 10 demultiplexes the data broadcast content and stores it in a buffer (not shown).

  Note that the receiving unit 10 is preferably configured to include a plurality of tuners. In this case, a plurality of data streams broadcast simultaneously through different channels can be demodulated in parallel. When the receiving unit 10 includes a plurality of tuners, the data broadcast content multiplexed on each of the plurality of data streams is stored in the above-described buffer. Of course, if the function of demodulating a plurality of data streams simultaneously broadcast via different channels is unnecessary, the receiving unit 10 may be configured by a single tuner. Thereby, the cost of the recording / reproducing apparatus 1 can be reduced.

  The program-independent content extraction unit 11 extracts program-independent content from the data broadcast content stored in the buffer described above. Program-independent content refers to data broadcast content that is not related to the content of the corresponding program content. The program-independent content extracted by the program-independent content extraction unit 11 is supplied to the program-independent content recording unit 12. The program-independent content recording unit 12 records the program-independent content supplied from the program-independent content extraction unit 11 in the content storage unit 16.

  The program dependent content extraction unit 13 extracts program dependent content from the data broadcast content stored in the buffer described above. Program-dependent content refers to data broadcast content related to the content of the corresponding program content. The program dependent content extracted by the program dependent content extracting unit 13 is supplied to the program dependent content recording unit 14. The program dependent content recording unit 14 records the program dependent content supplied from the program dependent content extracting unit 13 in the content storage unit 16.

  The program content recording unit 15 records the data stream demodulated by the receiving unit 10 in the content storage unit 16. When the receiving unit 10 includes a plurality of tuners, each of the plurality of data streams demodulated in parallel by the receiving unit 10 is recorded in the content storage unit 16.

  The content storage unit 16 is a recording device for storing program content and data broadcast content. For example, an HD (Hard Disk) drive, an SSD (Solid State Disk) drive, a DVD (Digital Versatile Disk) drive, a BD (Blu-ray) -ray Disk: registered trademark) drive. The content storage unit 16 may be configured by a single recording device or a plurality of recording devices. In the latter case, a configuration in which program content and data broadcast content are recorded on different recording devices (for example, a configuration in which program content is recorded on an HD drive or a BD drive and data broadcast content is recorded on an SSD drive) is adopted. Also good.

  The program-independent content reading / reproducing unit 17 reads out the program-independent content from the content storage unit 16. In particular, when program-independent content is encoded, the program-independent content is obtained by decoding the encoded data. The program-independent content obtained by the program-independent content reading / reproducing unit 17 is supplied to the content drawing unit 20. At this time, the program-independent content reading / reproducing unit 17 may process the read or decoded program-independent content and supply it to the content drawing unit 20. Note that a method of selecting program-independent content to be read by the program-independent content reading / playback unit 17 will be described later with reference to another drawing.

  The program dependent content reading / reproducing unit 18 reads program dependent content from the content storage unit 16. In particular, when program content is encoded, the program-dependent content is obtained by decoding the encoded data. The program dependent content obtained by the program dependent content reading / reproducing unit 18 is supplied to the content drawing unit 20. At this time, the program-dependent content reading / reproducing unit 18 may process the read or decoded program-dependent content and supply it to the content drawing unit 20.

  The program content read / play unit 19 reads the program content from the content storage unit 16 and plays it. Here, reproducing the program content means, for example, generating a video signal representing the program content by decoding a data stream representing the program content. The video signal representing the program content obtained by the program content reading / reproducing unit 19 is supplied to the content drawing unit 20.

  The content drawing unit 20 generates a screen including program-independent content, program-dependent content, and program content. The screen generation by the content drawing unit 20 is, for example, a program-independent content read / playback unit 17, a program-dependent content read / playback unit 18, and a program-independent content supplied from the program content read / playback unit 19 and a program-dependent This is realized by shaping content and program content and drawing on the screen. The screen generated by the content drawing unit 20 is supplied to the display terminal 2 such as a television receiver or a PC monitor.

[Specific examples of data broadcasting contents]
Data broadcasting content includes BML content and non-BML content. Here, the BML content refers to multimedia content composed of a BML document and mono-media data referenced from the BML document. Non-BML content refers to data broadcast content other than BML content, and for example, text data such as program information (or program detailed information) corresponds to this.

  Various information is included in the BML content. Individual information included in the BML content is referred to as “sub-content” in the present specification. This sub-content includes those that are not related to the content of the corresponding program content and those that are related to the content of the corresponding program content. In addition, non-BML contents include those that are not related to the contents of the corresponding program contents and those that are related to the contents of the corresponding program contents.

  In the present specification, data broadcast content that is not related to the content of the corresponding program content is provided as a sub-content of BML content or provided as non-BML content. Regardless of whether it is present, it is called “program-independent content”. In addition, data broadcasting content related to the content of the corresponding program content is asked whether it is provided as sub-content of BML content or non-BML content. It is called “program-dependent content”.

  Hereinafter, program-independent content and program-dependent content will be described with specific examples.

  First, a specific example of program-independent content will be described with reference to FIG. Examples of the program-independent content include the following. The information listed below is program-independent content regardless of whether it is provided as sub-contents included in BML content or non-BML content.

  (1) Weather information: This includes weather forecasts and weekly weather forecasts. The weather forecast is composed of weather, precipitation, temperature, etc. for each time zone (for example, every 3 hours). The weekly weather forecast is composed of daily weather, maximum temperature, minimum temperature, probability of precipitation, and the like. The weather information may include related information such as washing index, pollen information, lightning information, typhoon information, power prediction, radioactivity information, and volcanic ash information. As an example of weather information, a typical weather forecast is shown in FIG.

  (2) Holiday / Night Medical Information: Information regarding holiday medical services or night medical services, which includes clinic name, address, telephone number, reception time (for each day of the week), remarks, etc. Medical treatment subjects may be included in the holiday / night medical information. In areas where night medical care is carried around on each day of the week, it is better to include the turn day. Typical holiday / nighttime medical care information is shown in FIG.

  (3) Disaster prevention information: This includes earthquake information, tsunami information, volcano information, typhoon information, and disaster prevention related information. As an example of the disaster prevention information, typical disaster prevention related information is shown in FIG. In addition, the disaster prevention related information shown in FIG. 2C is for re-notifying the information notified using the disaster prevention administrative radio using data broadcasting.

  (4) Traffic information: Train operation information and traffic jam information fall under this category. As an example of traffic information, typical train operation information is shown in FIG.

  (5) Regional event information: Information related to events held in a specific region, and includes an event name, a holding period, contact information, and the like. The regional event information may include the address of the venue, a map around the venue, and the like. A specific example of regional event information is shown in FIG.

  (6) Notification from the local government: Information notified from the local government, and the content is not particularly limited. A typical notification from the local government is shown in FIG.

  (7) Other information: This includes store information and stock price information. The store information is information regarding stores (restaurants, cake stores, coffee shops, clothes stores, accessory stores, etc.) existing in a specific area, and includes store names, addresses, telephone numbers, product photos, and the like. The store information may include a map around the store. Store information about restaurants is sometimes called gourmet information.

  Next, a specific example of program-dependent content will be described with reference to FIG.

  FIG. 3 is a diagram showing BML content 30 corresponding to a cooking program. As shown in FIG. 3, the BML content 30 includes a sub-content 31 indicating a material and a sub-content 32 indicating how to make the material. These sub contents 31 to 32 are all program dependent contents related to the contents of the program contents (cooking program).

  Although FIG. 3 illustrates the program-dependent content provided as the sub-content of the BML content, the program-dependent content is not limited to this. That is, there is a program-dependent content provided as non-BML content. For example, text data representing program information (or detailed program information) is an example of program-dependent content provided as non-BML content.

  The program-dependent content may be broadcast without being synchronized with the corresponding program content in addition to the content being broadcast in synchronization with the corresponding program content. For example, this is the case where program-dependent content corresponding to program content broadcast every Friday at 9 pm is broadcast every day. Such program-dependent content is updated at an appropriate timing. For example, program-dependent content corresponding to program content that is broadcast every Friday at 9 pm is updated every Sunday at 11 am. In this case, program-dependent content related to the content of the program content broadcast last time is broadcast until 11:00 am on Sunday, including 9 pm on Friday. For example, at 8:00 pm on Thursday, program-dependent content related to the content of the program content broadcast last time is broadcast. Note that such association between the program-dependent content and the program content includes, for example, a word included in the re-broadcast program-dependent content and a word included in the title or program information (or program detailed information) of the program content. Based on matching.

[Outline of content recording function]
Next, an outline of the content recording function of the recording / reproducing apparatus 1 will be described with reference to FIG. FIG. 4 is a conceptual diagram showing an outline of the content recording function of the recording / reproducing apparatus 1.

  In digital broadcasting, as described above, the corresponding data broadcast content is broadcast simultaneously with the program content. In the channel A in the example shown in FIG. 4, data broadcast content including program-dependent content A1 and program-independent content A1 to A2 (event information 1-2) is broadcast simultaneously with program content A1, and simultaneously with program content A2. Data broadcast content including program-dependent content A2 and program-independent content A1 to A2 is being broadcast.

  Similarly, in channel B shown in FIG. 4, data broadcast content including program-dependent content B1 and program-independent content B (weather information) is broadcast simultaneously with program content B1, and program-dependent content is simultaneously transmitted with program content B2. Data broadcast content including B2 and program-independent content B is broadcast. In addition, on channel C shown in FIG. 4, data broadcast content including program-dependent content C1 and program-independent content C (holiday / night medical information) is broadcast simultaneously with program content C1, and simultaneously with program content C2, Data broadcast content including dependent content C2 and program-independent content C is broadcast.

  In the recording / reproducing apparatus 1, the program-independent content extraction unit 11 extracts the program-independent content A1-A2 from the data broadcast content received by the receiving unit 10 simultaneously with the program content A1-A2, and the program-dependent content extraction unit 13 Extracts the program-dependent contents A1 to A2. The program-independent content A1 to A2 and the program-dependent content A1 to A2 are recorded in the content storage unit 16 by the program-independent content recording unit 12 and the program-dependent content recording unit 14.

  Similarly, the program-independent content extracting unit 11 extracts the program-independent content B from the data broadcast content received by the receiving unit 10 at the same time as the program content B1 and B2, and the program-dependent content extracting unit 13 is set up in the program-dependent content B1 to B2. Extract B2. The program-independent content B and the program-dependent contents B1 to B2 are recorded in the content storage unit 16 by the program-independent content recording unit 12 and the program-dependent content recording unit 14. Further, the program-independent content extracting unit 11 extracts the program-independent content C from the data broadcast content received by the receiving unit 10 at the same time as the program content C1 and C2, and the program-dependent content extracting unit 13 is programmed with the program-dependent content C1 and C2. To extract. The program-independent content C and the program-dependent contents C1 to C2 are recorded in the content storage unit 16 by the program-independent content recording unit 12 and the program-dependent content recording unit 14.

  A specific example of program-independent content extraction / recording processing by the program-independent content extracting unit 11 and the program-independent content recording unit 12 will be described later with reference to another drawing.

[Specific example of program-independent content extraction / recording processing]
Next, a specific example of the program-independent content extraction / recording process will be described with reference to FIG. FIG. 5 is a flowchart showing a specific example of the program-independent content extraction / recording process. The program-independent content extraction / recording process shown in FIG. 5 is for extracting / recording the local event information, and includes the following steps.

  Step S11: First, the in-device area identification code stored in the recording / reproducing apparatus 1 in advance is read out by the program-independent content extracting unit 11. The in-device area identification code is information indicating the use region, and here, the postal code of the use region is used as the in-device identification code.

  Instead of using the postal code of the use area as the in-device area identification code, a configuration using the address of the use area as the in-device area identification code may be adopted. This is because the address in the use area can be converted into the postal code in the use area by referring to the address / zip code conversion table.

  Step S12: Next, the receiver 10 reads the program-independent content acquisition broadcast station information stored in the recording / reproducing apparatus 1 in advance. The program-independent content acquisition broadcast station information is information indicating a broadcast station from which the program-independent content is acquired, and is, for example, a channel number.

  Step S13: Subsequently, the receiving station 10 selects a broadcast station indicated by the program-independent content acquisition broadcast station information acquired in Step S12. Furthermore, the data stream superimposed on the broadcast wave broadcast from the broadcast station is demodulated by the receiving unit 10, and the data broadcast content is demultiplexed from the data stream. The demultiplexed data broadcast content is stored in a buffer. Step S13 is continued until at least all data broadcast contents (data broadcast contents for one data carousel) are stored in the buffer.

  Step S14: The program-independent content extraction unit 11 specifies an in-content area identification code that matches the in-device area identification code read in step S11. Here, the content area identification code is information indicating the distribution target area (reception area) of the data broadcasting content, and the standard area code (identification code defined by the Ministry of Internal Affairs and Communications for use in statistics) or the unique identification code is the content. Used as an internal area identification code. When a standard area code is used as the content area identification code, refer to the conversion table that defines the correspondence between the zip code and the standard area code to identify the content area identification code that matches the device area identification code. It can be done by.

  Step S15: Subsequently, the program-independent content extraction unit 11 extracts sub-contents that match the content-internal region identification code specified in Step S14 as regional event information. Here, the sub-content conforming to the content area identification code is a data broadcast including the content area identification code identical to the content area identification code identified in step S14 among the data broadcast contents stored in the buffer. Refers to content.

  The regional event information extracted in step S15 is supplied from the program-independent content extraction unit 11 to the program-independent content recording unit 12. The program-independent content recording unit 12 executes steps S16 to S19 described below using each of the regional event information supplied from the program-independent content extracting unit 11 as target regional event information.

  Step S16: First, the program-independent content recording unit 12 determines whether or not the target area event information has already been recorded in the content storage unit 16. If the target area event information has already been recorded in the content storage unit 16, the following steps S17 to S19 are skipped.

  Step S17: The event holding period of the event represented by the target area event information is specified by the program-independent content recording unit 12. The start date of the event holding period can be specified by, for example, extracting a character string that matches a predetermined pattern (such as “○ month × day to” or “○ month × day to”) from the target area event information. Further, the end date of the event holding period can be specified by, for example, extracting a character string that matches a predetermined pattern (such as “up to XX month × day” or “up to XX month × day”) from the target area event information. .

  Step S18: The program-independent content recording unit 12 sets an information display period (a period during which target area event information is to be displayed on the program content selection screen 60 and the like described later) according to the event holding period specified in step S17. Is done. The start date of the information display period is set, for example, seven days before the start date of the event holding period specified in step S17. On the other hand, the end date of the information display period is set to the end date of the event holding period specified in step S17, for example.

  Step S19: The target region event information is recorded in the content storage unit 16 by the program-independent content recording unit 12. At this time, the information display period set in step S17 is also recorded in the content storage unit 16 in association with the target area event information.

  In the case of program-independent content including a region identification code and period information, even program-independent content other than region event information can be similarly extracted and recorded by the extraction / recording process shown in FIG. it can. In addition, if the content is a program-independent content including an observation station number such as weather information, it can be extracted and recorded in the same manner by replacing the area identification code with the observation station number in the extraction / recording process shown in FIG. it can.

[Overview of program content selection function]

  The thumbnail image display area 61 is an area for displaying a thumbnail image (which may be a still image or a moving image) corresponding to any program content stored in the content storage unit 16. The thumbnail image displayed in the thumbnail image display area 61 may be provided from a broadcasting station as data broadcast content, or is generated by the recording / playback apparatus 1 by being extracted from program content. Also good.

  For example, the user can switch the thumbnail image displayed in the thumbnail image display area 61 by operating the cross key on the remote controller. Further, for example, by pressing a determination button on the remote controller, the program content corresponding to the thumbnail image displayed in the thumbnail image display area 61 can be selected as the program content to be reproduced.

  The program-independent content display area 62 is an area for displaying the program-independent content selected by the recording / playback apparatus 1 as a display target among the program-independent contents stored in the content storage unit 16. The program content selection screen 60 shown in FIG. 6 includes program-independent content A1 to A2 (regional event information 1-2), program-independent content B (weather information), and program-independent content C (holiday / (Night medical information) is selected by the recording / reproducing apparatus 1 as a display target.

  Such display of the program content selection screen 60 is realized by the operation of the recording / reproducing apparatus 1 as described below.

  That is, upon receiving a user operation instructing display of the program content selection screen 60, the program-independent content reading / playback unit 17 selects (1) program-independent content A1 to A2, B, and C to be displayed, (2) The selected program-independent content is read from the content storage unit 16, and (3) the read program-independent content is supplied to the content drawing unit 20. Then, the content drawing unit 20 draws the program-independent contents A1 to A2, B, and C supplied from the program-independent content reading / playback unit 17 in the program-independent content display area 62 as shown in FIG. A program content selection screen 60 is generated.

  It should be noted in FIG. 6 that the corresponding program-independent contents A1 to A2, B, and C are displayed even though the program contents A1 to A2, B1 to B2, and C1 to C2 are not reproduced. It is. That is, the reproduction of the program content and the display of the corresponding program-independent content are performed independently.

  When such a configuration is adopted, for example, even when program content is not reproduced, program-independent content corresponding to the program content can be displayed. This makes it possible to provide the user with information that has been rarely viewed by the user.

  Note that, here, a configuration has been shown in which program-independent content is displayed together with thumbnail images when selecting program content to be played back, but the scene in which program-independent content is displayed is not limited to this. For example, when the received program content is reproduced in real time, a configuration may be adopted in which program-independent content is displayed together with a playback video of the received program content. In this case, instead of displaying the program content selection screen 60 on the display terminal 2, a display screen in which the thumbnail image display area 61 is replaced with the playback video display area on the program content selection screen 60 may be displayed on the display terminal 2. As a result, the user can view the program-independent content stored in the content storage unit 16 while viewing the program content reproduced in real time.

[Specific example of program-independent content selection / display processing]
Next, a specific example of program-independent content selection / display processing will be described with reference to FIG. FIG. 7 is a flowchart showing a specific example of program-independent content selection / display processing. The program-independent content selection / display process shown in FIG. 7 should be displayed in the program-independent content display area 62 shown in FIG. 6 from the local event information (program-independent content) group stored in the content storage unit 16. This is for selecting regional event information, and includes the following steps.

  Step S21: When the display of the program content selection screen 60 is instructed by the user, the current date and time is acquired by the program-independent content reading / reproducing unit 17.

  When the acquisition of the current date and time is completed, the program-independent content reading / playback unit 17 executes steps S22 to S24 described below using each piece of regional event information recorded in the content storage unit 16 as target regional event information. To do.

  Step S22: The program-independent content reading / playback unit 17 reads the information display period associated with the target area event information from the content storage unit 16.

  Step S23: The program-independent content reading / playback unit 17 determines whether or not the current date and time acquired in step S21 is included in the information display period read in step S22. When it is determined that the current date and time acquired in step S21 is not included in the information display period read in step S22, the following step S23 is skipped.

  Step S24: The target region event information is read from the content storage unit 16 by the program-independent content reading / reproducing unit 17. The target area event information read by the program-independent content reading / playback unit 17 is displayed in the program-independent content display area 62 of the content viewing screen 60 by the content drawing unit 20.

  In addition, as long as it is a program-independent content stored in association with the display period, even a program-independent content other than the regional event information can be similarly selected and displayed by the selection / display process shown in FIG. .

[Other program content selection screen]
The recording / reproducing apparatus 1 can also display another program content selection screen 80 shown in FIG. 8 on the display terminal 2 instead of the program content selection screen 60 shown in FIG. Hereinafter, the program content selection screen 80 will be described with reference to FIG.

  As shown in FIG. 8, the program content selection screen 80 includes a genre selection area 81, a genre display area 82, a program content selection area 83, a BML content reduced display area 84, a program summary information display area 85, a sub A content expansion display area 86, a weather information display area 87, and a program-independent content display area 88 are included.

  The genre selection area 81 displays a plurality of predetermined genres as selection candidates, and a UI (User Interface) for allowing the user to select one genre from these selection candidates. In the example illustrated in FIG. 8, a UI in which a panel in which a genre name of each genre as a selection candidate is described is arranged in the virtual three-dimensional space with a depth is displayed in the genre selection area 81. In this UI, a panel on which the genre name selected by the user is described is arranged in the foreground.

  In the genre display area 82, the genre name of the genre selected in the genre selection area 81 is displayed. In the example shown in FIG. 8, “genre 1” is displayed in the genre display area 82.

  In the program content selection area 83, program contents belonging to the genre selected in the genre selection area 81 among the program contents recorded in the content storage unit 16 are selected, and one program content is selected from these selection candidates. A UI for allowing the user to select is displayed. In the example shown in FIG. 8, a UI in which buttons describing the titles of program contents to be selection candidates are arranged in a grid pattern is displayed in the program content selection area 83. In this UI, a button describing the title selected by the user (with the cursor placed) is highlighted.

  In the BML content reduction display area 84, the BML content corresponding to the program content selected in the program content selection area 83 is reduced and displayed. In the example shown in FIG. 8, BML content including a map (image), description (text), and a thumbnail video is reduced and displayed in the BML content reduction display area 84.

  In the program summary information display area 85, program summary information corresponding to the program content selected in the program content selection area 83 is displayed. If the program summary information includes a URL, the program summary information display area 85 also displays a “HP (homepage)” button. When this “HP (homepage)” button is pressed, the recording / reproducing apparatus 1 starts displaying the web page specified by the URL included in the program summary information. In the program summary information display area 85, a “play” button is also displayed. When the “play” button is pressed, the recording / playback apparatus 1 starts playing the program content selected in the program content selection area 83.

  The program summary information displayed in the program summary information display area 85 may be broadcast or distributed separately from the data broadcast content, or may be extracted from the BML content. Examples of program summary information that is broadcast or distributed separately from the data broadcast content include ADAMS-EPG and G Guide (registered trademark).

  The program summary information display area 85 further includes buttons corresponding to the sub contents included in the BML content displayed in the BML content reduction display area 84 (in the example shown in FIG. 8, a “map” button, “ "Description" button and "Movie" button) are also displayed. When any one of these buttons is pressed, the recording / reproducing apparatus 1 displays the sub content corresponding to the pressed button in the sub content enlarged display area 86 in an enlarged manner. In the example shown in FIG. 8, the map (image) is enlarged and displayed in the sub-content enlarged display area 86.

  In the weather information display area 87, weather information recorded as program-independent content in the content storage unit 16 is displayed. The weather information displayed in the weather information display area 87 does not need to be weather information corresponding to the currently selected program content. In addition, as shown in FIG. 8, the date of the day, the time at that time, and the like may be displayed together in the weather information display area 87.

  In the program-independent content display area 88, the program-independent content selected by the user among the program-independent contents stored in the content storage unit 16 is displayed. In the example shown in FIG. 8, a “today's information” button, a “news” button, an “event” button, and a “holiday medical care” button are displayed, and program-independent content corresponding to the pressed button (FIG. 8). In the example shown in (2), regional event information) is displayed.

  When the user selects any title in the program content selection area 83, a “save” button and a “transfer” button are displayed in the genre display area 82 described above. When the “Save” button is pressed, the recording / reproducing apparatus 1 saves a set of configuration information necessary for reproducing the currently displayed program content selection screen 80 in an internal recording medium or an external recording medium. When the “transfer” button is pressed, the recording / reproducing apparatus 1 transfers a set of data necessary for reproducing the currently displayed program content selection screen 80 to a mobile phone terminal or the like.

  As described above, the program content selection screen 80 is mainly intended to present program summary information in order to allow the user to select program content to be reproduced, and is conventionally intended to reproduce program content. This recording / reproducing apparatus does not exist. By using the program content selection screen 80, it is possible to browse the program summary information related to the program content stored in the content storage unit 16 as if turning a magazine. When the program content to be viewed is found on the program content selection screen 80, the program content can be viewed by pressing the “play” button described above.

[Modification 1]
Finally, a modified example of the configuration of the recording / reproducing apparatus 1 shown in FIG. 1 will be described with reference to FIGS. 9 to 11 are block diagrams showing modifications of the recording / reproducing apparatus 1.

  In the modification shown in FIG. 9, the recording / reproducing apparatus 1 and the display terminal 2 are connected by an HDMI (registered trademark) cable. For this reason, the recording / reproducing apparatus 1 and the display terminal 2 are provided with HDMI interfaces 91 to 92, respectively.

  In this case, the program content is transmitted as a video signal / audio signal via the TMDS channel of the HDMI cable, whereas the data broadcast content is transmitted through the Ethernet (registered trademark) channel (HEC: HDMI Ethernet Channel) of the HDMI cable. Is transmitted as encoded data. Therefore, the program-independent content reading / reproducing unit 17 and the program-dependent content reading / reproducing unit 18 are provided not in the recording / reproducing apparatus 1 but in the display terminal 2.

  The wired connection medium between the recording / reproducing device 1 and the display terminal 2 is not limited to the HDMI cable, and may be a D terminal cable or an RCA cable. Further, the recording / reproducing apparatus 1 and the display terminal 2 may be connected by using MHL (Mobile High-definition Link) (application trademark). In this case, the connection between the recording / reproducing apparatus 1 and the display terminal 2 may be a wireless connection.

  In the modification shown in FIG. 10, the recording / reproducing apparatus 1 and the display terminal 2 are connected by a wireless LAN. For this reason, the recording / reproducing apparatus 1 and the display terminal 2 are provided with wireless LAN interfaces 101 to 102. Of course, a wired LAN connection may be used instead of the wireless LAN connection. Further, power line communication using PLC (Power Line Control) may be used.

  In this case, the program content and the data broadcast content are transmitted as encoded data via the wireless LAN. Therefore, the program-independent content reading / reproducing unit 17, the program-dependent content reading / reproducing unit 18, and the program content reading / reproducing unit 19 are provided not in the recording / reproducing apparatus 1 but in the display terminal 2.

  In the modification shown in FIG. 11, the recording / reproducing apparatus 1 and the display terminal 2 are connected by a wireless LAN, as in the example shown in FIG. For this reason, the recording / reproducing apparatus 1 and the display terminal 2 are provided with wireless LAN interfaces 101 to 102.

  However, a configuration is adopted in which the program content conversion unit 110 is provided in the recording / playback apparatus 1 and the program content is sent to the display terminal 2 after the resolution is reduced to encoded data with a low decoding load. For this reason, even when the bandwidth available for transmission of program content is narrow or when the decoding capability of the program content reading / playback unit 19 provided in the display terminal 2 is low, the program content is reproduced without interruption. be able to.

  10 and 11 exemplify a wireless LAN (IEEE802.11 series) as a standard of wireless communication for connecting the recording / reproducing apparatus 1 and the display terminal 2, but the present invention is not limited to this. For example, WirelessHD (registered trademark) may be used instead of wireless LAN (IEEE802.11 series).

[Modification 2]
As described above, the recording / reproducing apparatus 1 according to the present embodiment has the following configuration in order to achieve the purpose of effectively presenting data broadcast content that has been rarely browsed by the user to the user. I have. That is, (1) a receiving unit 10 that receives a data stream, (2) a program content recording unit 15 that records program content included in the data stream in a content storage unit 16, and (3) included in the data stream. A data-independent content recording unit 12 or a program-dependent content recording unit 14 that records data broadcasting content corresponding to the program content in the content storage unit 16; and (4) the content storage unit 16. A program content reading / reproducing unit 19 for reproducing the recorded program content; and (5) a program-independent content reading / reproducing unit 17 for reading the data broadcast content recorded in the content storage unit 16 or a program-dependent content reading / reproduction. 18 and (6) reading / reproducing the program content Independently of the reproduction of the program content by 19, the content drawing unit 20 for displaying the data broadcast content read from the program content recording unit 15 by the program-independent content reading / reproducing unit 17 or the program-dependent content reading / reproducing unit 18 And.

  However, a data broadcast content recording / playback device in which the program content recording / playback function is omitted from the recording / playback device 1 according to the present embodiment is replaced with a program content recording / playback device having a program content recording / playback function (conventional television receiver or recorder device). Etc.) can also achieve the above object.

  The data broadcast content recording / playback apparatus includes, for example, (a) receiving means for receiving a data stream, and (b) data broadcast content included in the data stream, the data broadcast content corresponding to each program content A data broadcast content recording means for recording in the storage section; (c) a data broadcast content reading means for reading the data broadcast content recorded in the content storage section; and (d) the data independent of the reproduction of the program content. The broadcast content reading means can comprise data broadcast content display means for displaying the data broadcast content read from the content storage unit.

  Here, (a) the receiving means may be configured similarly to the receiving unit 10 in the present embodiment, for example. Further, (b) the data broadcast content recording means may be configured in the same manner as the program-independent content recording unit 12 or the program-dependent content recording unit 14 in the present embodiment, for example. Further, (c) the data broadcast content reading means may be configured in the same manner as the program-independent content reading / reproducing unit 17 or the program-dependent content reading / reproducing unit 18 in the present embodiment, for example. Further, (d) the data broadcast content display means may be configured in the same manner as the content drawing unit 20 in the present embodiment, for example.

  Hereinafter, a configuration example of such a data broadcast content recording / playback apparatus will be described with reference to FIG. FIG. 12 is a block diagram showing a further modification of the recording / reproducing apparatus 1 shown in FIG. FIG. 12 shows the recording / playback apparatus 1 shown in FIG. 1 with the program content recording / playback function omitted.

  That is, the recording / reproducing apparatus 1 shown in FIG. 12 differs from the recording / reproducing apparatus 1 shown in FIG. 1 in that the program content is not provided with the recording unit 15 and the program content reading / reproducing unit 19. The recording / reproducing apparatus 1 shown in FIG. 12 is the same as the recording / reproducing apparatus 1 shown in FIG.

  Therefore, in the recording / playback apparatus 1 shown in FIG. 12, the data storage content is stored in the content storage unit 16, but the program content (specifically, the data stream demodulated by the reception unit 10) is not stored. In addition, the content drawing unit 20 generates a screen including data broadcast content, but does not generate a screen including program content. That is, the screen including the data broadcast content is supplied from the recording / playback apparatus 1 to the display terminal 2, but the screen including the program content is not supplied.

  Thus, the present invention can be implemented not only by an apparatus having a program content recording / playback function but also by an apparatus not having a program content recording / playback function. Even in such a case, the data broadcast content (program-dependent content and program-independent) is displayed on the display terminal 2 independently of the program content, like the recording / reproducing apparatus 1 shown in FIG. Can do. Therefore, similar to the recording / reproducing apparatus 1 shown in FIG. 1, it is possible to provide effects such as the ability to present data broadcast content that has been rarely viewed by the user to the user.

  For example, various information terminals (for example, personal computers, mobile phone terminals, smartphones, PDAs, etc.) have the same configuration as the recording / playback apparatus 1 shown in FIG. Data broadcast content can be presented to the user.

  Thus, the user can determine program content to be viewed or recorded later by a television receiver, a recorder, or the like with reference to the data broadcast content presented by the information terminal.

  In addition to this, there are various methods for using the data broadcast content obtained by the information terminal. For example, the user can send an SNS (Social Network Service) an arbitrary message regarding the data broadcast content from the information terminal through the Internet. You can also post to other message posting sites.

  Further, the user can use a dedicated application for referring to a part of information (for example, cooking recipe information, map information, etc.) of the data broadcasting content when necessary (for example, shopping, You can also browse while traveling.

  In addition, the user cuts out a part of information of the data broadcasting content and embeds this information in a file for an arbitrary application so that the user can use the arbitrary application (for example, a familiar application) when necessary. Information can also be referenced.

  That is, by using an information terminal, a user can obtain data broadcast contents even when they are away from home without operating a television receiver or a recorder or viewing program contents. It is possible to effectively use the obtained data broadcasting content.

[Modification 3]
Hereinafter, a modified example of the process of acquiring the data broadcast content will be described. The recording / reproducing apparatus 1 (receiving unit 10) of the present embodiment can also be configured to acquire data broadcast contents of a plurality of channels with a single tuner. As a result, the recording / reproducing apparatus 1 can acquire data broadcasting contents of a plurality of channels without providing a tuner for each channel.

  For example, the recording / playback apparatus 1 shown in FIG. 12 does not have a program content recording / playback function and does not need to simultaneously record or play back a plurality of program contents, and therefore broadcasts simultaneously through different channels. A function for demodulating a plurality of data streams in parallel is unnecessary. For this reason, in such a recording / reproducing apparatus 1, the structure provided with a smaller number (for example, one) tuner may be employ | adopted without providing the tuner for every channel. If the recording / reproducing apparatus 1 has at least one tuner, it is possible to acquire data broadcast contents of a plurality of channels using the one tuner by the procedure described below.

  Hereinafter, a specific example of processing for acquiring data broadcast contents of a plurality of channels by one tuner will be described with reference to FIG. FIG. 13 is a flowchart showing a specific example of processing for acquiring data broadcast contents of a plurality of channels by one tuner in the recording / reproducing apparatus 1 according to the present embodiment.

  In short, the procedure shown in FIG. 13 is performed by sequentially selecting a plurality of channels that are targeted for data broadcast content acquisition by a single tuner included in the receiving unit 10, and the single tuner selecting a channel. Each time, the program-dependent content recording unit 14 records the program-dependent content included in the data stream of the selected channel in the content storage unit 16, and the program-independent content recording unit 12 stores the channel-selected content of the selected channel. The program-independent content included in the data stream is recorded in the content storage unit 16.

  Specifically, the recording / reproducing apparatus 1 performs the processes of steps S31 to S38 described below for each of the plurality of channels that are the acquisition targets of the data broadcast content.

  Step S31: One channel is selected by one tuner 10 included in the receiving unit 10. Thereby, the receiving unit 10 receives and demodulates the data stream of the one channel.

  Step S32: The receiving unit 10 determines whether or not the program-dependent content included in the data stream obtained in step S31 has already been acquired.

  For example, the receiving unit 10 searches the content storage unit 16 and determines whether or not the program-dependent content included in the data stream obtained in step S31 has already been acquired.

  If it is determined that “It has already been acquired” (step S32: Yes), the recording / reproducing apparatus 1 advances the process to step S35. On the other hand, when it is determined that “not already acquired” (step S32: No), the recording / reproducing apparatus 1 advances the process to step S33.

  Note that the program-dependent content included in the data stream obtained in step S31 may have a newer version or content than the acquired program-dependent content. Also in this case, the recording / reproducing apparatus 1 advances a process to step S33.

  Step S33: The program dependent content extraction unit 13 extracts program dependent content from the data stream obtained in step S31.

  Step S34: The program-dependent content recording unit 14 records the program-dependent content extracted in step S33 in the content storage unit 16.

  Step S35: The receiving unit 10 determines whether or not the channel selected in step S31 is an acquisition target of program-independent content. As already described, the receiving unit 10 refers to the program-independent content acquisition broadcast station information stored in advance in the recording / reproducing apparatus 1 so that the channel selected in step S31 acquires the program-independent content. It can be determined whether or not it is a target.

  When it is determined that “the program is not subject to content acquisition” (step S35: Yes), the recording / reproducing apparatus 1 advances the process to step S36. On the other hand, when it is determined that “the program is not subject to acquisition of program-independent content” (step S35: No), the recording / reproducing apparatus 1 skips steps S36 to S38, returns the process to step S31, and continues. The process for the next channel is performed.

  Step S36: The program-independent content extracting unit 11 extracts program-independent content from the data stream obtained in step S31.

  Step S37: The program-independent content recording unit 12 determines whether to record the program-independent content extracted in step S36 in the content storage unit 16.

  For example, the program-independent content recording unit 12 searches the content storage unit 16 for a program-independent content having the same name (same ID) as the program-independent content extracted in step S36.

  When the version of the searched program-independent content is the same as the version of the program-independent content extracted in step S36, the program-independent content recording unit 12 reads “program-independent content extracted in step S36. Is not recorded in the content storage unit 16 ”(step S37: No). In this case, the recording / reproducing apparatus 1 skips step S38, returns the process to step S31, and continues to process the next channel.

  On the other hand, when the version of the searched program-independent content is older than the version of the program-independent content extracted in step S36, the program-independent content recording unit 12 “program-independent content extracted in step S36”. Is recorded in the content storage unit 16 ”(step S37: Yes). In this case, the recording / reproducing apparatus 1 advances the process to step S38.

  Step S38: The program-independent content recording unit 12 records the program-independent content extracted in step S36 in the content storage unit 16. Thereafter, the recording / reproducing apparatus 1 returns the process to step S31, and subsequently performs the process for the next channel.

  In step S38, when an old version of program-independent content having the same name (same ID) has already been recorded in the content storage unit 16, the program-independent content recording unit 12 uses the program-independent content extracted in step S36. Overwrite and update the old version of program-independent content.

  At this time, the recording / reproducing apparatus 1 may delete the old version of the program-independent content, and the old version of the program-independent content is stored in the recording / reproducing apparatus 1 so that the user can refer to it at an arbitrary timing. It may be stored. In this case, the recording / reproducing apparatus 1 may determine whether the old version of the program-independent content is deleted as described above or stored as described above according to the content. Good.

  For example, when an old version of program-independent content is particularly useful for the user, such as weather information, disaster prevention information, traffic information, and local event information, the recording / reproducing apparatus 1 uses the program-independent content. May be deleted.

  On the other hand, when the old version of the program-independent content is useful to the user even if it is not the latest information such as store information, the recording / reproducing apparatus 1 stores the program-independent content in the recording / reproducing apparatus 1. You may make it store. In this case, the recording / reproducing apparatus 1 may change the storage period according to the contents of the old version of the program-independent content.

  For example, when the power is turned on, the recording / reproducing apparatus 1 starts a series of processes shown in FIG. The recording / reproducing apparatus 1 repeatedly executes a series of processes shown in FIG. 13 while the power is on. Thus, the latest data broadcast content of each of the plurality of channels is always recorded in the content storage unit 16 of the recording / playback apparatus 1. Then, when the power is turned off, the recording / reproducing apparatus 1 ends the series of processes shown in FIG. However, when the power supply is in the standby state, the series of processing shown in FIG. 13 is not completed. As a result, the recording / reproducing apparatus 1 can obtain the latest data broadcast content even during standby. The start / end timing of the series of processes shown in FIG. 13 is not limited to the above, and may be any timing.

  According to the above procedure, the recording / reproducing apparatus 1 can acquire data broadcast contents of a plurality of channels even when only one tuner is provided. In other words, any device provided with at least one tuner can be used as the recording / reproducing device 1.

  Note that in the recording / playback apparatus 1 having only one tuner, it is necessary to execute some processing (for example, program content recording processing or playback processing) that requires the tuner during the data broadcast content acquisition processing. May occur. In this case, the recording / reproducing apparatus 1 may interrupt the data broadcast content acquisition process and perform the requested process using the tuner. Then, as soon as the requested processing is completed, the data broadcast content acquisition processing may be resumed using the tuner.

  Of course, even when the recording / reproducing apparatus 1 includes two or more tuners, it is possible to acquire data broadcast contents of a plurality of channels by using one of the tuners. In this case, the recording / reproducing apparatus 1 does not need to allocate the remaining tuner to the data broadcast content acquisition process, and thus can effectively use the remaining tuner. For example, the recording / playback apparatus 1 can execute a process for acquiring data broadcast content by one tuner and a certain process (for example, a program content recording process or a playback process) by another tuner in parallel. It becomes possible.

[Program, storage medium]
Each block of the recording / reproducing apparatus 1 may be realized in hardware by a logic circuit formed on an integrated circuit (IC chip), or may be realized in software using a CPU (Central Processing Unit). Good.

  In the latter case, the recording / reproducing apparatus 1 includes a CPU that executes instructions of a program that realizes each function, a ROM (Read Only Memory) that stores the program, a RAM (Random Access Memory) that expands the program, the program, A storage device (recording medium) such as a memory for storing various data is provided. An object of the present invention is a recording medium on which a program code (execution format program, intermediate code program, source program) of a control program of the recording / reproducing apparatus 1 which is software for realizing the functions described above is recorded so as to be readable by a computer This can also be achieved by supplying to the recording / reproducing apparatus 1 and reading and executing the program code recorded on the recording medium by the computer (or CPU or MPU).

  Examples of the recording medium include tapes such as magnetic tapes and cassette tapes, magnetic disks such as floppy (registered trademark) disks / hard disks, and disks including optical disks such as CD-ROM / MO / MD / DVD / CD-R. IC cards (including memory cards) / optical cards, semiconductor memories such as mask ROM / EPROM / EEPROM / flash ROM, PLD (Programmable logic device), FPGA (Field Programmable Gate Array), etc. Logic circuits can be used.

  The program code may be supplied to the recording / reproducing apparatus 1 via a communication network. The communication network is not particularly limited as long as it can transmit the program code. For example, the Internet, intranet, extranet, LAN, ISDN, VAN, CATV communication network, virtual private network, telephone line network, mobile communication network, satellite communication network, and the like can be used. The transmission medium constituting the communication network may be any medium that can transmit the program code, and is not limited to a specific configuration or type. For example, even with wired lines such as IEEE 1394, USB, power line carrier, cable TV line, telephone line, ADSL (Asymmetric Digital Subscriber Line) line, infrared rays such as IrDA and remote control, Bluetooth (registered trademark), IEEE 802.11 wireless, HDR ( It can also be used by radio such as High Data Rate (NFC), Near Field Communication (NFC), Digital Living Network Alliance (DLNA), mobile phone network, satellite line, and digital terrestrial network.
