Hereinafter, in order to explain the present invention in more detail, modes for carrying out the present invention will be described with reference to the accompanying drawings.
Embodiment 1 FIG.
With reference to FIG.1 and FIG.2, the digital broadcast receiver 100 of Embodiment 1 of this invention is demonstrated.
The first antenna 1a receives a digital broadcast wave such as terrestrial digital television broadcast. Broadcast waves of terrestrial digital television broadcasting are multiplexed by the so-called “Orthogonal frequency-division multiplexing (OFDM) system”. The first tuner unit 2a converts a broadcast wave of one of the broadcast waves received by the first antenna 1a into a digital signal. The first OFDM demodulator 3a demodulates the digital signal converted by the first tuner 2a, and outputs a so-called “transport stream (TS)”.

  The first receiving unit 4a is configured by the first antenna 1a, the first tuner unit 2a, and the first OFDM demodulating unit 3a. Similarly, the second receiving unit 4b is configured by the second antenna 1b, the second tuner unit 2b, and the second OFDM demodulating unit 3b.

  The video / audio acquisition unit 51 of the control unit 5 acquires video data and audio data from the TS output from the first OFDM demodulation unit 3a or the second OFDM demodulation unit 3b. The decoding unit 6 decodes the video data and audio data acquired by the video / audio acquisition unit 51. The display unit 7 displays the video data decoded by the decoding unit 6 as a video. The audio output unit 8 outputs the audio data decoded by the decoding unit 6 as audio.

  The program information acquisition unit 52 of the control unit 5 acquires program information such as EIT [schedule] or EIT [p / f] from the TS output from the first OFDM demodulation unit 3a or the second OFDM demodulation unit 3b. The program information acquisition unit 52 associates channel number, program name, program start time, program end time, parental age information (viewing restriction age information) such as “Parental rating” included in the acquired program information, This is stored in the storage unit 9.

  The viewing restriction determination unit 53 of the control unit 5 among the information input to the operation input unit 10 (hereinafter referred to as “user operation information”) is a channel to be selected by the first receiving unit 4a (hereinafter referred to as “channel selection destination”). User operation information indicating “channel”) is received via the operation receiving unit 11. The viewing restriction determination unit 53 acquires the program information of the channel selected by the user operation information from the program information stored in the storage unit 9.

  Here, the storage unit 9 stores information indicating the age of the user input to the operation input unit 10 (hereinafter referred to as “set age information”). Based on the parental age information of the program of the selected channel indicated by the user operation information and the set age information stored in advance in the storage unit 9, the viewing restriction determination unit 53 determines whether the program of the selected channel is a user. It is determined whether the program is a viewing-restricted program.

  The tuner control unit 56 of the control unit 5 selects a channel on which the first tuner unit 2a converts a broadcast wave when the viewing restriction determination unit 53 determines that the program of the channel to be selected is not the user's viewing restriction program. Switching to the station channel. On the other hand, when the viewing restriction determination unit 53 determines that the program on the selected channel is a user's viewing restricted program, the tuner control unit 56 selects a channel on which the first tuner unit 2a converts the broadcast wave. The switch to the station channel is stopped. In addition, the tuner control unit 56 sequentially switches channels for the second tuner unit 2b to convert broadcast waves in accordance with the signal output from the program information acquisition unit 52.

  The list generation unit 54 of the control unit 5 acquires the program information of each channel stored in the storage unit 9. The list generation unit 54 includes a channel number, a program name, a program start time, a program end time, parental age information, and the like of each channel acquired from the storage unit 9 according to the determination result of the viewing restriction determination unit 53. A table is generated and displayed on the display unit 7. Further, the list generation unit 54 generates and displays a message indicating that viewing of the program is restricted (for example, a message “This program cannot be viewed”) according to the determination result of the viewing restriction determination unit 53. This is displayed on the unit 7.

  The warning sound generation unit 55 of the control unit 5 generates a warning sound indicating that viewing of the program is restricted according to the determination result of the viewing restriction determination unit 53 and outputs the warning sound to the audio output unit 8. .

  The first tuner unit 2a, the second tuner unit 2b, the first OFDM demodulation unit 3a, the second OFDM demodulation unit 3b, the control unit 5, the decoding unit 6, the storage unit 9, and the operation receiving unit 11 constitute the digital broadcast receiving apparatus 100. ing.

  The first tuner unit 2a, the second tuner unit 2b, the first OFDM demodulator unit 3a, the second OFDM demodulator unit 3b, the control unit 5, the decoding unit 6 and the operation receiving unit 11 are, for example, a CPU (Central Processing Unit) or a dedicated integration It is composed of a circuit or the like. The storage unit 9 is configured by, for example, an HDD (Hard Disk Drive) or a semiconductor memory.

  The display part 7 and the audio | voice output part 8 are comprised by the display and speaker of the navigation apparatus mounted in the vehicle, for example. Alternatively, the display unit 7 and the audio output unit 8 are configured by a display and a speaker integrated with the digital broadcast receiving apparatus 100. Or the display part 7 and the audio | voice output part 8 are comprised by the display and speaker of the portable information terminal which were brought in into the vehicle.

  The operation input unit 10 includes, for example, a remote controller that performs infrared communication or short-range wireless communication with the operation reception unit 11. Or the operation input part 10 is comprised by the touchscreen comprised integrally with the display of the display part 7. FIG. Or the operation input part 10 is comprised by the touch key provided adjacent to the display of the display part 7. FIG.

Next, with reference to FIG. 3, the operation of the digital broadcast receiving apparatus 100 configured as described above will be described focusing on the operation of the control unit 5.
Here, the digital broadcast receiving apparatus 100 is mounted on a vehicle, and the vehicle is running. The first receiving unit 4a receives a broadcast wave of an arbitrary channel (hereinafter referred to as “selected channel”), and the display unit 7 and the audio output unit 8 output video and audio of the program of the selected channel. ing. The storage unit 9 stores preset age information in advance.

  First, in step ST1, the program information acquisition unit 52 acquires program information of all channels that can be received by the second reception unit 4b. At this time, the program information acquisition unit 52 acquires not only program information of a program currently broadcast on each channel but also program information of a program scheduled to be broadcast in the future. The program information acquisition unit 52 stores the channel number, program name, program start time, program end time, parental age information, and the like included in the program information of each channel in the storage unit 9 in association with each other.

  Next, in step ST <b> 2, the viewing restriction determination unit 53 receives user operation information indicating a channel selection destination channel via the operation reception unit 11.

  Next, in step ST <b> 3, the viewing restriction determination unit 53 acquires parental age information of the program of the selected channel indicated by the user operation information from the program information stored in the storage unit 9. Further, the viewing restriction determination unit 53 indicates that the age indicated by the parental age information (hereinafter referred to as “parental age”) of the program of the selected channel is the age indicated by the set age information acquired from the storage unit 9 (hereinafter “setting”). It is determined whether it is over the age). If the parental age of the channel selection channel program is lower than the set age, or if the parental age information is not included in the program information of the channel selection channel program (step ST3 “NO”), then step In ST4, the tuner control unit 56 switches the channel of the first receiving unit 4a to the channel to be selected.

  On the other hand, when the parental age of the program of the channel to be selected exceeds the set age (step ST3 “YES”), then, in step ST5, the warning sound generation unit 55 generates a warning sound and generates a voice output unit. 8 to output. Alternatively, the list generation unit 54 generates a message indicating that “this program cannot be viewed” and causes the display unit 7 to display the message. At this time, the tuner control unit 56 does not switch the channel of the first receiving unit 4a to the selected channel.

  Next, in step ST <b> 6, the list generation unit 54 acquires program information of each channel stored in the storage unit 9. The list generation unit 54 generates a list including the channel number, program name, program start time, program end time, parental age information, and the like of each channel and causes the display unit 7 to display the list.

  FIG. 4 shows an example of a list generated by the list generating unit 54. A list II is displayed in the first display area I of the display unit 7. In Table II, the program information of the program name “XX” broadcast from 18:00 to 19:00 on 20 channels (ch) and broadcast from 18:30 to 20:00 on 23ch The program information of the program name “ΔΔ” and the program information of the program name “XX” broadcast from 18:30 to 20:00 on 30ch are included.

  The 20ch and 30ch program information does not include parental age information, and the 23ch program information includes parental age information indicating 12 years old. Therefore, it is displayed in the list II that the parental age of the 23ch program is 12 years old.

  When the set age is less than 12 years (for example, 11 years old), the list generation unit 54 generates a list IIa excluding 23ch whose parental age exceeds the set age, as shown in FIG. It is good to do.

  Further, when the set age is less than 12, the list generation unit 54 may change the 23 ch program whose parental age exceeds the set age to a display mode different from other programs. For example, as illustrated in FIG. 6, the list generation unit 54 may generate a list IIb in which a 23ch program is represented with a thickness different from that of other programs. Or the list production | generation part 54 may produce | generate the list which represented the program of 23ch with the color or brightness | luminance different from another program. Or the list production | generation part 54 may produce | generate the list which blinked the 23ch program.

  In step ST5, the warning sound generation unit 55 outputs a warning sound or the list generation unit 54 displays a message. However, both of these may be performed.

  In addition, after the warning sound generation unit 55 outputs a warning sound in step ST5 or the list generation unit 54 displays a message, the list generation unit 54 displays the list in step ST6. The order of these steps is not limited. The list generation unit 54 may display the list at the same time as the warning sound generation unit 55 outputs a warning sound or the list generation unit 54 displays a message.

  7-10 has shown an example of the screen of the display part 7 when the list production | generation part 54 displays a message and a list simultaneously. As shown in FIG. 7, in the first display area I of the display unit 7, a message may be displayed indicating that the program on the selected channel cannot be viewed by being superimposed on the list IIb. Alternatively, as shown in FIG. 8, in the second display area III of the display unit 7, a message indicating that the program of the selected channel cannot be viewed independently of the list IIb may be displayed. At this time, the message may blink for a predetermined time. Further, when the message does not fit in the second display area III, the message may be scrolled in the horizontal direction of the screen.

  Further, the message generated by the list generation unit 54 is not limited to a message indicating that “this program cannot be viewed”. As shown in FIG. 9 or FIG. 10, for example, when the channel selection channel is 23ch, a message including the program name of the program of the channel selection channel and the reason why viewing is restricted may be generated. The list generation unit 54 may generate an icon made up of a still image or a moving image instead of or in addition to these messages.

  As described above, the digital broadcast receiving apparatus 100 according to the first embodiment uses the storage unit 9 that stores the set age information indicating the user's age and the received signal of the channel searched by the second receiving unit 4b to determine the channel. Program information acquisition unit 52 for acquiring program information including parental age information of the program, parental age information included in the program information of the channel selected by the first receiving unit 4a, set age Based on the information, a viewing restriction determination unit 53 that determines whether or not the program on the channel to be selected is a user's viewing restricted program, and a program on the channel to be selected is judged to be a viewing restricted program. A warning sound generation unit 55 that generates a warning sound indicating that viewing is restricted and outputs the warning sound to the audio output unit 8 in a state where the control unit 56 stops switching to the channel to be selected. The program of the channel searched for by the second receiving unit 4b is registered in a state where the program of the selected channel is determined to be a viewing-restricted program and the tuner control unit 56 has stopped switching to the selected channel. And a list generation unit 54 that generates a list and displays it on the display unit 7. As a result, a warning sound is output when the program on the selected channel is a viewing-restricted program, so that the user can be notified that viewing of the program on the selected channel is restricted. Furthermore, by displaying a list of receivable programs, the user can perform a tuning operation smoothly.

  In addition, the list generation unit 54 changes the viewing-restricted program to a display mode different from other programs. By changing and displaying the color or luminance of the viewing restricted program, the user can visually distinguish the viewing restricted program. In this case, parental age information may not be displayed in the list. Even if parental age information is not displayed, the user can visually recognize the viewing-restricted program.

  Alternatively, the list generation unit 54 excludes viewing-restricted programs from the list. By not displaying the viewing-restricted program in the list, it is possible to prevent tuning to a viewing-restricted program due to an erroneous operation by the user. In this case, parental age information may not be displayed in the list.

  In addition to the list, the list generation unit 54 displays a message indicating that viewing of the program is restricted. By displaying a message in addition to the list, the user can be surely notified that viewing of the program of the selected channel is restricted.

  In addition, the list generation unit 54 displays parental age information for each program in the list. As a result, it is possible to present to the user an easily viewable program and a program whose viewing is restricted.

  Note that the warning sound generation unit 55 may output a voice that reads out the message generated by the list generation unit 54 instead of the warning sound.

  In addition, the operation input unit 10 and the operation reception unit 11 are not essential components of the present invention, and the operation input unit 10 and the operation reception unit 11 may be omitted from the digital broadcast receiving apparatus 100 illustrated in FIGS. 1 and 2. good. In this case, for example, the storage unit 9 may store predetermined set age information in advance when the digital broadcast receiving apparatus 100 is shipped. The tuner control unit 56 may switch the first receiving unit 4a from the channel being selected to the channel to be selected according to the broadcast wave reception state of the first receiving unit 4a. The viewing restriction determination unit 53 may acquire information indicating that switching from the selected channel to the selected channel is performed from the tuner control unit 56 instead of the user operation information.

  Moreover, the program information acquisition part 52 is good also as what acquires the program information of each channel in a fixed period, while the digital broadcast receiver 100 is turned on. The program information acquisition unit 52 may delete old program information from the program information stored in the storage unit 9. Also, the viewing restriction determination unit 53 determines whether the parental age of the selected channel exceeds the set age when the current time is between the start time and the end time included in the program information of the selected channel. It may be determined whether or not.

The operation of the control unit 5 is not limited to the flowchart shown in FIG. Hereinafter, a modified example of the operation of the control unit 5 will be described with reference to FIGS. 11 and 12.
The flowchart of FIG. 11 shows an operation in which the program information acquisition unit 52 acquires program information. First, in step ST21, the program information acquisition unit 52 sends a signal to the tuner control unit 56, and the channel of the second reception unit 4b is any channel that can receive broadcast waves (hereinafter referred to as “channel X”). Switch to.

  Next, in step ST22, the program information acquisition unit 52 acquires program information from the broadcast wave of channel X received by the second reception unit 4b. At this time, the program information acquisition unit 52 acquires not only program information of a program currently broadcast on the channel X but also program information of a program scheduled to be broadcast in the future. The program information acquisition unit 52 stores the channel number, program name, program start time, program end time, parental age information, and the like included in the acquired program information in association with each other in the storage unit 9.

  Next, in step ST23, the program information acquisition unit 52 deletes the program information of the program whose channel end time is older than the current time from the program information of channel X already stored in the storage unit 9.

  Next, in step ST24, the program information acquisition unit 52 determines whether or not the program information has been acquired from all channels capable of receiving broadcast waves by the second reception unit 4b. When the program information has not been acquired from all receivable channels (step ST24 “NO”), the program information acquisition unit 52 returns to the process of step ST21. On the other hand, when the program information is acquired from all receivable channels (step ST24 “YES”), the program information acquisition unit 52 ends the process.

  The program information acquisition unit 52 repeats the processing of step ST21 to step ST24 at a constant cycle while the digital broadcast receiving device 100 is powered on. Thereby, the memory | storage part 9 can always memorize | store the newest program information.

The flowchart of FIG. 12 shows an operation in which the control unit 5 performs program viewing restriction. In FIG. 12, the same steps as those in the flowchart shown in FIG.
Subsequent to step ST2, in step ST11, the viewing restriction determination unit 53 determines whether or not the program information of the selected channel is stored in the storage unit 9.

  When the program information of the channel selection channel is stored in the storage unit 9 (step ST11 “YES”), the viewing restriction determination unit 53 then selects the channel selection channel stored in the storage unit 9 in step ST12. Get program information for. Further, the viewing restriction determination unit 53 determines whether or not the current time is between the program start time and the program end time included in the program information of the selected channel. When the current time is between the program start time and the program end time (step ST12 “YES”), the control unit 5 executes the processes of steps ST3 to ST6.

  If the program information of the selected channel is not stored in the storage unit 9 (step ST11 “NO”), or the program start time and the program end time are included in the program information of the selected channel. If not (step ST12 “NO”), the control unit 5 proceeds to the process of step ST4, and exceptionally prioritizes smooth channel switching of the first receiving unit 4a over viewing restrictions based on parental age information. It is good as a thing.

  The storage unit 9 may hold the stored program information even after the digital broadcast receiving apparatus 100 is turned off. When the digital broadcast receiving apparatus 100 is turned on, the control unit 5 compares the current time with the end time of each program information stored in the storage unit 9 and determines the program information whose end time is older than the current time. It may be deleted.

  Also, the tuner control unit 56 selects a channel on which the second tuner unit 2b converts the broadcast wave when the viewing restriction determination unit 53 determines that the program on the channel to be selected is not the user's viewing restriction program. In addition to switching to the channel, when the viewing restriction determination unit 53 determines that the program on the channel to be selected is a user's viewing restricted program, the channel on which the second tuner unit 2b converts the broadcast wave is selected as the channel to be selected. It is good also as what stops switching. Further, the tuner control unit 56 may sequentially switch the channel for the first tuner unit 2a to convert the broadcast wave according to the signal output from the program information acquisition unit 52. Thus, when the second receiving unit 4b receives a broadcast wave of the channel being selected, the first receiving unit 4a can search for the channel X.

Embodiment 2. FIG.
FIG. 13 is a block diagram illustrating a configuration of a main part (control unit 5a) of digital broadcast receiving apparatus 100 according to the second embodiment. With reference to FIG. 13, a digital broadcast receiving apparatus 100 that can select a program from a list will be described. Since the digital broadcast receiving apparatus 100 of the second embodiment has the same configuration as the digital broadcast receiving apparatus 100 shown in FIG. 1 except for the control unit 5a, the description will be given with reference to FIG. In FIG. 13, the same components as those of the digital broadcast receiving apparatus 100 of the first embodiment shown in FIG.

  The list generation unit 54 of the control unit 5a receives user operation information for selecting any program from the list displayed on the display unit 7 among the user operation information input to the operation input unit 10, and receives the operation. It is to be received via the part 11. The list generation unit 54 displays a cursor that moves according to the received user operation information so as to be superimposed on the list.

  The viewing restriction determination unit 53 of the control unit 5a determines whether or not the parental age of the program selected from the list by the user operation information exceeds the set age stored in advance in the storage unit 9. ing.

  The warning sound generation unit 55 of the control unit 5a receives a warning sound when the viewing restriction determination unit 53 notifies that the program whose parental age exceeds the set age is selected from the list according to the user operation information. Is generated and output to the audio output unit 8.

  The tuner control unit 56 of the control unit 5a performs the first operation when a program whose parental age is not more than a set age or a program whose parental information is not included in the program information is selected from the list according to user operation information. The channel of the receiving unit 4a is switched to the channel of the selected program.

Next, with reference to FIG. 14 and FIG. 15, the operation of the digital broadcast receiving apparatus 100 configured as described above will be described focusing on the operation of the control unit 5 a.
FIG. 14 shows an example of a list generated by the list generating unit 54. A list IIb is displayed in the first display area I of the display unit 7. A rectangular cursor IV is displayed so as to be superimposed on the list IIb. The cursor IV moves on the list IIb according to the user operation information input to the operation input unit 10, and indicates that any program is selected.

  At this time, when a 23-ch program whose parental age exceeds the set age is selected from the programs displayed in the list IIb, the warning sound generation unit 55 generates a warning sound and sends it to the audio output unit 8. Output. The tuner control unit 56 does not switch the channel of the first receiving unit 4a to the selected channel.

  On the other hand, when a 20ch or 30ch program that does not include parental age information is selected from the programs displayed in the list IIb, the tuner control unit 56 selects the channel of the first receiving unit 4a. Switch to the program channel.

  Alternatively, as shown in FIG. 15, the list generation unit 54 may generate a list IIc in which the 23ch program whose parental age exceeds the set age cannot be selected with the cursor IV. For example, 23ch program information is displayed in white, and even if the user moves the cursor IV to select a 23ch program, the list generation unit 54 skips the 23ch program and moves and displays the cursor IV. So it can not be selected. Alternatively, in a state where the cursor IV is moved to the 23ch program, the operation accepting unit 11 cannot accept the user operation information for selecting the channel of the first receiving unit 4a, so that the 23ch program cannot be selected.

  As described above, in the digital broadcast receiving apparatus 100 according to the second embodiment, the list generation unit 54 displays the cursor IV indicating that any program in the list is selected, and displays the viewing-restricted program. A list that cannot be selected by the cursor IV is displayed. The tuner control unit 56 switches the channel of the first receiving unit 4a to the channel of the program selected by the cursor IV. By making it impossible to select a program that cannot be viewed, it is possible to prevent tuning to a viewing-restricted program due to an erroneous operation by the user.

  Alternatively, the list generation unit 54 displays a cursor IV indicating that any program is selected in the list. The viewing restriction determination unit 53 determines whether or not the program selected by the cursor IV is a viewing restriction program.
