  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration example of a television receiver 1 for viewing a digital broadcast (digital data broadcast) to which the present invention is applied.

  In the figure, the receiving unit 21 receives a broadcast digital data broadcast signal and outputs it to the demodulation unit 22. The demodulator 22 demodulates the digital data broadcast signal output from the receiver 21 to generate a transport stream (TS).

  The TS decoding unit 23 decodes the transport stream, and generates and outputs element packets each including video data, audio data, text data, and the like. Among the element packets output from the TS decoding unit 23, the element packets of video data and audio data are acquired by the AV decoding unit 25, and data other than the video data and audio data (for example, text data, still image data, etc.) Are acquired by the digital broadcast data acquisition unit 24.

  The AV decoding unit 25 generates a video / audio signal based on the element packet of the video data and the audio data, and outputs the video / audio signal to the synthesis unit 26. The element packet data acquired by the digital broadcast data acquisition unit 24 is converted into an on-screen display (OSD) signal by the OSD generation unit 27 as necessary, and output from the AV decoding unit 25. An on-screen display signal is superimposed on the output video signal and output to the display 52.

  Further, the I / O interface 28 receives a signal output from the remote controller (remote commander) 51 and outputs command information corresponding to the received signal to the bus 41. The remote controller 51 is provided with keys corresponding to commands for instructing the television receiver 1 to “reproduce data broadcast (digital data broadcast)”, “display program description”, and the like. By pressing a command key, for example, an infrared signal corresponding to the command is output from the remote controller 51.

  A CPU (Central Processing Unit) 29 executes various processes according to a program stored in a ROM (Read Only Memory) 31 or a program loaded in a RAM (Random Access Memory) 30. The RAM 30 also appropriately stores data necessary for the CPU 29 to execute various processes. The ROM 31 also stores an application data dedicated data content table which will be described later.

  The storage unit 17 is configured by a nonvolatile memory such as NVRAM (Non Volatile RAM) or an HDD (Hard Disk Drive), and is used in application processing of the television receiver 1 such as program guide data and recording reservation data. The recorded data is recorded as appropriate.

  The above-described units are connected to each other by a bus 41.

  FIG. 2 is a block diagram illustrating a functional configuration example of software executed by the CPU 29 and causing the television receiver 1 to execute reproduction of data broadcasting or various application processes.

  In the figure, the receiver state management unit 71 controls the switching of the operation mode of the browser 72 in response to the command transmitted from the remote controller 51. The browser 72 is configured to operate in either a data broadcast reproduction mode for reproducing a data broadcast or an application processing mode for executing an application process such as display of a program description. Based on this command, the above-described operation mode is switched.

  In addition, the receiver state management unit 71 controls the start or stop of the digital broadcast data reception processing unit 73 in accordance with the switching of the operation mode of the browser 72. The digital broadcast data reception processing unit 73 is a functional block that controls the digital broadcast data acquisition unit 24 of FIG. 1, and when a predetermined event or the like is received in the data broadcast, the digital broadcast data reception processing unit 73 receives it from the browser 72 via the memory management unit 76. Perform event notifications. The digital broadcast data reception processing unit 73 is activated when the browser 72 is operating in the data broadcast reproduction mode, and is stopped when the browser 72 is operating in the application processing mode.

  The EPG data acquisition unit 75 extracts data related to EPG (Electronic Program Guide) from the received data broadcast signal, and stores the extracted data in the program information database 77. The reservation database 78 stores recording reservation data for programs specified by the user via a GUI (Graphical User Interface) displayed by the browser 72.

  The application dedicated data content group 79 is content that is read when the browser 72 operates in the application processing mode. For example, a plurality of contents corresponding to a plurality of application processes are stored in advance.

  In response to a request from the browser 72, the file system 74 accesses the program information database 77, the reservation database 78, or the application-specific data content group 79, reads the data designated by the browser 72, and passes through the memory management unit 76. To the browser 72.

  As described above, FIG. 2 is a block diagram of software, and each functional block shown in FIG. 2 is actually configured by a program that executes processing of the functional block.

  Next, processing of the receiver state management unit 71 will be described with reference to the flowchart of FIG.

  In step S1, the receiver state management unit 71 determines whether or not the remote control code output from the remote controller 51, that is, the remote controller 51 has received data transmitted to the television receiver, and receives the remote control code. Wait until it is determined that it has been done. If it is determined in step S1 that a remote control code has been received, the process proceeds to step S2.

  In step S2, the receiver state management unit 71 checks the operation mode of the browser 72, and in step S3, determines whether the current operation mode of the browser 72 is the data broadcast reproduction mode or the application processing mode. Note that the current operation mode of the browser 72 is stored in advance in the RAM 30 or the like by processing in step S26 in FIG. 4 or step S46 in FIG.

  When it is determined in step S3 that the operation mode of the browser 72 is the data broadcast reproduction mode, the process proceeds to step S4, and the receiver state management unit 71 performs mode switching process 1 described later with reference to FIG. Execute. Thereby, the operation mode of the browser 72 is switched from the data broadcast reproduction mode to the application processing mode as necessary.

  If it is determined in step S3 that the operation mode of the browser 72 is the application processing mode, the process proceeds to step S5, and the receiver state management unit 71 performs a mode switching process 2 described later with reference to FIG. Execute. Thereby, the operation mode of the browser 72 is switched from the application processing mode to the data broadcast reproduction mode as necessary.

  Next, the details of the mode switching process 1 in step S4 of FIG. 3 will be described with reference to the flowchart of FIG.

  In step S21, the receiver state management unit 71 checks the received remote control code. Thereby, the contents of the remote control code are analyzed. As described above, the remote controller 51 outputs a remote control code for instructing various application processes, data broadcast reproduction, and the like based on user operations.

  FIG. 5 shows an example of the remote control code. In this example, “program guide”, “program description”, “recording reservation”, “bookmark”, “registration call”, and “mail” are described as remote control codes for instructing application processing.

  The remote control code “program guide” is a remote control code corresponding to an application process for displaying the program guide on the display 52 of the television receiver 1. As the application-specific data content corresponding to the remote control code “program guide”, “file: ///application/epg/startup.bml ”. The application-specific data content is content for causing the browser 72 to execute application processing, and is configured as, for example, a data file described in a BML (Broadcast Markup Language) format. Note that the application-specific data content described in FIG. 5 is actually the address of the content, and by supplying this address to the file system 74, the content stored in advance becomes the application-specific data content group 79. Is read from.

  The remote control code “program description” is a remote control code corresponding to an application process for displaying a program description of a predetermined program on the display 52 of the television receiver 1, and application-specific data content corresponding to the remote control code “program description” ( "File: ///application/program/startup.bml".

  The remote control code “recording reservation” is a remote control code corresponding to application processing that accepts an operation input of a program recording reservation by the user in the television receiver 1, and is an application-dedicated data content corresponding to the remote control code “recording reservation”. , “File: ///application/reservation/startup.bml” is described.

  The remote control code “bookmark” is a remote control code corresponding to an application process for reproducing a predetermined content registered in advance (bookmark) in the television receiver 1, and application-specific data content corresponding to the remote control code “bookmark”. As “file: ///application/bookmark/startup.bml”.

  The remote control code “registration call” is used in an application process in the television receiver 1 for transmitting (calling) a connection request such as a videophone communication to a device (partner) registered in advance. This is a corresponding remote control code, and “file: ///application/registcal/startup.bml” is described as application-specific data content corresponding to the remote control code “registration call”.

  The remote control code “mail” is a remote control code corresponding to application processing for performing transmission / reception of e-mail, for example, in the television receiver 1. As the application-specific data content corresponding to the remote control code “registration call”, “ file: ///application/mail/startup.bml ".

  In this example, “data broadcasting” is described as a remote control code for instructing reproduction of data broadcasting. There is no application-specific data content corresponding to the remote control code “data broadcast”, and when the data broadcast is reproduced using the browser 72, the start-up content defined by a predetermined standard or the like is replaced by the browser instead of the application-specific data content. 72 is supplied as content for executing reproduction of the data broadcast.

  In the television receiver 1, a table associating various remote control codes and application-specific data contents as shown in FIG.

  Returning to FIG. 4, in step S22, the receiver state management unit 71 determines whether or not the remote control code checked in step S21 is a remote control code for application processing. In step S23, the browser 72 is notified of switching of the operation mode. In this case, since it is determined in step S3 of FIG. 3 that the operation mode of the browser 72 is the data broadcast reproduction mode, if the received remote control code is a remote control code for application processing, the browser 72 It is necessary to switch the operation mode to the application processing mode.

  In step S24, the receiver state management unit 71 notifies application-specific data content corresponding to the received remote control code (the remote control code checked in step S21). At this time, the receiver state management unit 71 refers to the table associating the various remote control codes described above with reference to FIG. 5 with the application-specific data content, and refers to the application-specific data content (actually corresponding to the received remote-control code). The address of the content). For example, when the remote control code checked in step S21 is “program guide”, “file: ///application/epg/startup.bml” is notified as application-specific data content corresponding to the remote control code “program guide”. Is done.

  In step S <b> 25, the receiver state management unit 71 stops the digital broadcast data reception processing unit 73. As described above, the digital broadcast data reception processing unit 73 is a block that notifies the browser 72 of the event via the memory management unit 76 when a predetermined event or the like is received in the data broadcast. The data reception processing unit 73 is activated when the browser 72 is operating in the data broadcast reproduction mode, and is stopped when the browser 72 is operating in the application processing mode. In this case, since the operation mode of the browser 72 is switched from the data broadcast reproduction mode to the application processing mode by the process of step S23, the digital broadcast data reception processing unit 73 is stopped.

  In step S <b> 26, the receiver state management unit 71 sets the operation mode of the browser 72 to “application processing”, and stores the set operation mode in the RAM 30 or the like.

  If it is determined in step S22 that the remote control code checked in step S21 is not a remote control code for application processing, the processing in steps S23 to S26 is skipped.

  In this way, the browser 72 operating in the data broadcast reproduction mode is controlled so as to operate in the application processing mode in response to the received remote control code.

  Next, the details of the mode switching process 2 in step S5 in FIG. 3 will be described with reference to the flowchart in FIG.

  In step S41, the receiver state management unit 71 checks the received remote control code. Thereby, the contents of the remote control code are analyzed.

  In step S42, the receiver state management unit 71 determines whether or not the remote control code checked in step S41 is a remote control code for application processing, and is not a remote control code for application processing (that is, a remote control code for data broadcast reproduction). If it is determined, the process proceeds to step S43 to notify the browser 72 of switching of the operation mode. In this case, since it is determined in step S3 of FIG. 3 that the operation mode of the browser 72 is the application processing mode, if the received remote control code is a remote control code for data broadcast reproduction, the browser 72 It is necessary to switch the operation mode to the data broadcast reproduction mode.

  In step S44, the receiver state management unit 71 activates the digital broadcast data reception processing unit 73. As described above, the digital broadcast data reception processing unit 73 is activated when the browser 72 is operating in the data broadcast reproduction mode, and is stopped when the browser 72 is operating in the application processing mode. In this case, since the operation mode of the browser 72 is switched from the application processing mode to the data broadcast reproduction mode by the process of step S43, the digital broadcast data reception processing unit 73 is activated.

  In step S <b> 45, the receiver state management unit 71 notifies the browser 72 of startup content of data broadcasting. At this time, as described above, the receiver state management unit 71 notifies start-up content (actually, the address of the content) determined in advance by a standard or the like.

  In step S46, the receiver state management unit 71 sets the operation mode of the browser 72 to “data broadcast reproduction”, and stores the set operation mode in the RAM 30 or the like.

  If it is determined in step S42 that the remote control code checked in step S21 is a remote control code for application processing, the processing in steps S43 to S46 is skipped.

  In this way, the browser 72 operating in the application processing mode is controlled so as to operate in the data broadcast reproduction mode in response to the received remote control code.

  Next, the processing of the browser 72 will be described with reference to the flowchart of FIG. This process is executed in parallel while the receiver state management unit 71 executes the process described above with reference to FIGS.

  In step S81, the browser 72 determines whether or not switching of the operation mode is notified from the receiver state management unit 71, and waits until it is determined that switching of the operation mode is notified.

  In the process of step S23 of FIG. 4 or step S43 of FIG. 6, when switching of the operation mode is notified from the receiver state management unit 71, it is determined that the switching of the operation mode is notified in step S81. Proceed to step S82.

  In step S82, the browser 72 determines the current operation mode. If it is determined in step S82 that the current operation mode is the data broadcast reproduction mode, the process proceeds to step S83.

  In step S83, the browser 72 stops the reproduction of the data broadcast and switches the operation mode to the application processing mode.

  In step S84, the browser 72 receives the notification of the application-specific data content from the receiver state management unit 71. At this time, the application-specific data content (actually, the address of the content) notified from the receiver state management unit 71 in the process of step S24 in FIG. 4 is received.

  In step S85, the browser 72 downloads predetermined application-specific data content from the file system 74 based on the content received in step S84. For example, if the remote control code checked in step S21 in FIG. 4 is “program guide” and “file: ///application/epg/startup.bml” is notified as the application-specific data content in step S24, In step S85, the browser 72 supplies the content (“file: ///application/epg/startup.bml”) received in step S84 to the file system 74. As a result, the file system 74 reads the content (BML file or the like) corresponding to the application process for displaying the program guide from the application-specific data content group 79 and supplies it to the browser 72, whereby the application-specific data content is Downloaded.

  In step S86, the browser 72 presents the application-specific data content downloaded in step S84. At this time, the browser 72 reads a BML file or the like constituting the application-specific data content and, for example, a predetermined GUI (Graphical User Interface) used when displaying the program guide is displayed on the display 52 of the television receiver 1. Display. For example, the user can display a desired program guide by operating the remote controller 51 based on a GUI (Graphical User Interface) displayed on the display 52.

  In this way, the operation mode of the browser 72 is switched from the data broadcast reproduction mode to the application processing mode based on the remote control code, and application processing corresponding to the remote control code is performed.

  On the other hand, if it is determined in step S82 that the current operation mode of the browser 72 is the application processing mode, the process proceeds to step S87.

  In step S87, the browser 72 stops the application process and switches the operation mode to the data broadcast reproduction mode.

  In step S88, the browser 72 receives a notification of startup content corresponding to the data broadcast from the receiver state management unit 71. At this time, the startup content (actually, the address of the content) notified from the receiver state management unit 71 in the process of step S45 in FIG. 6 is received. Thereby, the browser 72 is controlled to read the startup content and execute reproduction of a predetermined data broadcast.

  In step S89, the browser 72 acquires the data content of the data broadcast.

  In step S90, the browser 72 presents the data content acquired in step S89 and reproduces the data broadcast.

  In this way, the operation mode of the browser 72 is switched from the application processing mode to the data broadcast reproduction mode based on the remote control code, and the data broadcast is reproduced.

  In addition, a process returns to step S81 after the process of step S86 or step S90.

  In this way, the processing of the browser 72 is performed in parallel with the processing of the receiver state management unit 71. In this way, when a program guide, program description, etc. are displayed on the display 52 of the television receiver 1 and application processing is being performed, video, audio, text information, etc. are displayed from the received data broadcast signal. Data broadcast playback processing for generating data is not executed in parallel, for example, there is no need to separately manage and manage a memory area used for data broadcasting and a memory area used for application processing , Resources can be used efficiently.

  In addition, since the processing of the application is performed by the browser 72 reading a BML file or the like constituting the application-specific data content, for example, in the function expansion or version upgrade of the television receiver 1, the content of the application processing is changed. In this case, it can be dealt with by simply replacing each content of the application-dedicated data content 79, and processing such as recompilation of various programs of the television receiver 1 becomes unnecessary. Therefore, a high-performance television receiver 1 can be configured at low cost.

  In the above embodiment, the television receiver has been described as an example, but the present invention can of course be applied to a personal computer or the like.
