  << Embodiment 1 >>

  <Embodiment 1: Overview> An overview of the present embodiment will be described. In the present embodiment, it is determined whether or not the data broadcast data of the terrestrial digital broadcast has been updated. The determination result indicates that the data broadcast has been updated, and control is performed to display only the video without displaying the data broadcast on the display unit. In such a case, the digital terrestrial broadcast receiving apparatus is characterized in that a notification indicating that the data broadcast data has been updated is displayed on the display screen.

  FIG. 1 shows an example of a digital terrestrial broadcast receiving apparatus according to this embodiment. FIG. 1 shows a scene in which a broadcast received by a terrestrial digital broadcast receiving apparatus is reproduced. (A) shows a state in which only the video is displayed without displaying the data broadcast. At this time, when the data broadcast data of the received digital terrestrial broadcast is updated, a notification indicating that the data of the data broadcast has been updated is given on the display screen. In other words, when a sports program (soccer in this example) is being broadcast as in this example, notification is made when the corresponding data broadcast data is updated (such as when the score of a soccer broadcast is updated). Do. The notification can be exemplified by a method of displaying a message as shown in (b) at the corner of the display area.

  <Embodiment 1: Configuration> FIG. 2 shows an example of functional blocks of the present embodiment. The “terrestrial digital broadcast receiving device” (0200) of this embodiment shown in FIG. 2 includes a “terrestrial digital broadcast receiving unit” (0201), a “display unit” (0202), and a “first control unit” (0203). And “determination unit” (0204) and “notification unit” (0205).

    (Terrestrial Digital Broadcast Receiving Device 0200) The “terrestrial digital broadcast receiving device” (0200) includes a wide variety of devices capable of receiving and playing back digital broadcasts. The digital terrestrial broadcast receiving apparatus in this case is assumed to be a small broadcast receiving apparatus such as a mobile phone.

    (Terrestrial digital broadcast receiving unit 0201) The “terrestrial digital broadcast receiving unit” (0201) receives the terrestrial digital broadcast. The terrestrial digital broadcast receiving unit receives broadcast waves sent from a broadcast station via an antenna. Unlike analog broadcasting, digital broadcasting is accompanied by data for data broadcasting in addition to video and audio. Data broadcasting is a method of streaming digital data such as still images, characters, and layout information on radio waves of a television, and is played back by dedicated software built in the receiver (television). There are two types, a stand-alone type and a linked type. The stand-alone type is a service for sending news and weather forecasts regardless of the contents of the program. Linked service is a service that sends data related to the program that you are watching. Utilizing interactive features, viewers can shop while watching the program, answer quizzes, and provide opinions and requests. It is possible to send. In this case, any kind of data broadcasting can be included.

    The data broadcasting data is configured in units called modules, and each module is accompanied by information such as a component tag, a module ID, a module name, and a module version. By storing the module information together with the module, the module existing on the storage unit can be uniquely identified.

    (Display unit 0202) The “display unit” (0202) displays the received digital terrestrial broadcast. In addition to normal video display, it is possible to display data for data broadcasting after analysis processing and present it to the user.

    (First Control Unit 0203) The “first control unit” (0203) can control to display only the video without displaying the data broadcast on the display unit (0202). In some cases, digital terrestrial broadcasts are displayed with the display lying sideways. At this time, in order to secure more TV broadcast areas, it is generally possible to display only video without displaying data broadcasts. Many.

    (Determining unit 0204) The “determining unit” (0204) determines whether or not the data broadcast data received is updated. In data broadcasting data configured in units called modules, DII (Download Information Indicator) is updated whenever a module is updated. The DII manages module information such as a component tag, a module ID, a module name, and a module version. When the updated DII is acquired, the module information in it is analyzed and the updated module is identified (details will be described later).

    Further, not only the currently viewed module but also the module linked from the currently viewed module may be checked for updates based on information such as the version. Although data broadcasting data is often updated with time, it is assumed that even when a part of the data broadcasting data is updated, the module can uniquely identify the part.

    (Notification unit 0205) The “notification unit” (0205) is a determination result that the determination result in the determination unit (0204) has been updated, and the first control unit (0203) controls to display only the video. If it is, a notification indicating that the data broadcast data has been updated is given on the display screen. The notification is executed because the user cannot recognize the update of the data broadcast in a state where only the video is displayed. The notification corresponds to display of a message for prompting the user to view the data broadcast. The case where data broadcasting is presented by a user operation will be described in detail in the second embodiment.

  Embodiment 1 Specific Configuration FIG. 3 is a schematic diagram illustrating an example of a specific configuration of the present embodiment. The “digital terrestrial broadcast receiver” (0300) of the present invention includes an “antenna unit” (0301), a “tuner” (0302), a “Demux unit” (0303), a “decoder unit” (0304), “Module construction unit” (0305), “Storage unit” (0306), “Module update check unit” (0307), “Display control unit” (0308), “Display unit” (0309), “ “Speaker” (0310), “content analysis / presentation processing unit” (0311), and “key control unit” (0312).

  (Processing in Digital Terrestrial Broadcasting Reception Unit, etc.) First, in digital broadcasting, a broadcast wave including data for data broadcasting in addition to video / audio is transmitted from a broadcasting station, which is received by an antenna unit (0301). The tuner (0302) performs inverse modulation. Furthermore, the Demux unit (0303) demultiplexes video, audio, and data broadcasting data. The demultiplexed data broadcasting data is subjected to module construction processing by the module construction unit (0305). The data broadcasting data is stored in the storage unit (0306) in units of constructed modules. At this time, module information such as a component tag, a module ID, a module name, and a module version is stored together with the module in the storage unit so that the module existing on the storage unit can be uniquely identified. The data broadcasting data is analyzed by a browser that displays the data broadcasting and can be presented to the user. Also, the video / audio data demultiplexed by the Demux unit is analyzed by the decoder unit (0304), and is passed through a display unit (0309) including a liquid crystal display and a speaker (0310) for reproducing audio. Video and audio to the user.

  (Processing in Judgment Unit, Notification Unit, etc.) Subsequently, the module update check unit (0307), based on the module information stored in the storage unit when the broadcast station updates the data broadcasting data, Determine whether the inside module has been updated. The module update check unit performs the above determination operation regardless of whether the data broadcast is presented on the screen. When the update of the module is detected, the update is notified to the display control unit (0308) composed of a liquid crystal controller or the like, and the updated module is displayed on the display unit (0309). Here, when an update is detected in a state where no data broadcast is presented, the content analysis / presentation processing unit (0311) has been updated when the display control unit (0308) is notified of the update. Is displayed, a message for prompting the user to view the data broadcast is displayed via the display unit (0309). The processing after the user input operation will be described in detail in the second embodiment.

  <Embodiment 1: Hardware Configuration> FIG. 4 is a schematic diagram illustrating an example of a hardware configuration of the present embodiment. The operation of each hardware component in the processing execution of the digital terrestrial broadcast receiving apparatus will be described using this figure. The terrestrial digital broadcast receiving apparatus includes a “CPU (central processing unit)” (0401), a “main memory” (0402), and a “storage device” in order to realize processing in the first control unit and the determination unit. Or storage medium) ”(0403). In addition to the hardware configuration unit, an “input / output interface” (0404) is provided in order to realize processing in the terrestrial digital broadcast receiving unit and the notification unit. Further, in order to realize processing in the display unit, although not described, it is connected to a display or the like via an input / output interface. These are connected to each other via a data communication path such as a “system bus” (0405), and perform transmission / reception and processing of information.

  The storage device stores various programs executed by the CPU (for example, a first control program (first control unit), a determination program (determination unit), a notification program (notification unit), etc.). The main memory also provides a work area that is an area for reading and developing the program in order to execute the program stored in the storage device. Furthermore, a plurality of memory addresses are assigned to the main memory and the storage device, respectively, and programs executed by the CPU exchange and process data by specifying and accessing the memory addresses. Is possible. The above is the function of each hardware configuration.

  First, when the terrestrial digital broadcast receiver is turned on, the first control program (address 01), determination program (address 02), and notification program (address 03) stored in the storage device are stored in the work area (address) of the main memory. 11, 12, 13).

  At this time, the terrestrial digital broadcast receiving apparatus takes in the terrestrial digital broadcast from the outside (broadcast station or the like) via the input interface, and extracts information on the module from the data broadcast data included in the broadcast wave. This module information is stored at any time in the address 04 of the storage device, and the received digital terrestrial broadcast is displayed on the connected display via the output interface.

  It is possible to select whether or not to display the data broadcast together with the video when displaying the terrestrial digital broadcast. The display of the video and the data broadcast is performed based on a command input by a user operation through the input interface. When a command to display only video without displaying data broadcast is input, the first control program developed in the work area of the main memory is executed by the CPU. The first control program stops the output of the data broadcast data to the graphic memory and performs only the output of the video data in order to perform control for displaying only the video on the display.

  In the terrestrial digital broadcast receiving apparatus, when the module information stored in the address 04 of the storage device is overwritten, the CPU executes a determination program developed in the work area of the main memory. The determination program determines that the data broadcast data has been updated by overwriting the module information. The determination result is temporarily stored in the work area of the main memory.

  The storing of the determination result is a trigger, and the notification program developed in the work area of the main memory is executed by the CPU. The notification program notifies that the data broadcast has been updated on condition that only the video is displayed on the display (refer to the graphic memory) in addition to the update of the data for data broadcasting. The notification that the data broadcast has been updated is executed by storing a message for prompting the user to view the data broadcast in the graphic memory.

  In the above description, each unit has been described as being configured by software, but may be configured by hardware.
