(Embodiment 1)
Hereinafter, an embodiment of the present invention will be described with reference to FIG. 1. Here, a case where a user views a terrestrial digital broadcast is illustrated. FIG. 1 is a block diagram showing a digital broadcast reception advertisement information output device 30 of this embodiment for receiving terrestrial digital broadcast.

  In FIG. 1, an antenna 1 receives a digital broadcast signal transmitted from a terrestrial broadcast station.

  The tuner 2 extracts a signal of a specific frequency from the high frequency digital modulation signal including video / audio data. Further, the tuner 2 includes a deinterleave circuit, an error correction circuit, and the like, thereby demodulating the selected digital modulation signal and outputting a transport stream.

  The demultiplexer (DEMUX) 3 separates the transport stream received from the tuner 2 into MPEG2 (Moving Picture Experts Group 2) video transport packets, audio transport packets, and PSI (Program Specific Information). The demultiplexer 3 supplies the video transport packet and the audio transport packet to the AV decoder 4, and supplies service information (SI: Service Information) included in the PSI to the system controller 13. As described above, a plurality of channels are multiplexed in the transport stream, and the process for selecting an arbitrary channel from among the channels is determined based on which arbitrary channel from the PSI is included in the transport stream. It becomes possible by taking out data such as whether the packet ID is multiplexed. In addition, not only the main channel but also the subchannel is multiplexed in the digital broadcast wave, and when the DEMUX control signal is supplied from the CPU 11 to the demultiplexer 3 to select the subchannel, the video transport packet in the subchannel or An audio transport packet is output. In addition, data broadcasting that provides still images, text information, and audio information is multiplexed with the digital broadcast wave. In program broadcasting, commercials (CMs) are inserted everywhere, but it is possible to incorporate advertisement information different from this commercial into subchannels and data broadcasting. Of course, it is also possible to provide a channel dedicated to advertising information. In the SI, for example, information indicating in which sub-channel advertisement information exists, and advertisement area information (for example, latitude / longitude information) indicating in which area the advertisement information should be broadcast are inserted. In addition, on the advertisement information sending side (broadcaster side), if a system capable of responding to sudden advertisement requests as well as sequentially sending the advertisement information requested in advance is prepared, When suddenly providing time service or the like, it is possible to place advertisement information informing on the broadcast wave in a timely manner.

  The AV decoder 4 includes a video decoder that decodes video transport packets and an audio decoder that decodes audio transport packets. The video decoder decodes the input variable length code to obtain a quantization coefficient and a motion vector, and performs inverse DCT conversion, motion compensation control based on the motion vector, and the like. The audio decoder decodes the input encoded signal to generate audio data. The video data generated by the decoding is output to the video processing circuit 5, and the audio data is output to the audio processing circuit 6. Although not shown, a data broadcast decoder is provided. The data broadcast decoder decodes the data broadcast packet to generate still image video data, audio data, and other information.

  The video processing circuit 5 performs D / A conversion on the video data and converts it into, for example, a composite signal in the NTSC format. The audio signal processing circuit 6 performs D / A conversion on the audio data to generate a right (R) sound analog signal and a left (L) sound analog signal. The video output circuit 7 and the audio output circuit 8 include a signal amplifier and the like. The monitor 9 performs video display based on the video signal supplied from the video output circuit 7. The speaker 10 performs audio output based on the audio signal supplied from the audio output circuit 8.

  The GPS (Global Positioning System) receiving circuit 12 includes an amplification circuit that amplifies a GPS signal received by the antenna 12a, a detection circuit, an A / D converter, a data demodulation circuit, and the like. The GPS receiving circuit 12 supplies demodulated data to the CPU 11.

  The beacon reception circuit 13 includes an amplification circuit that amplifies a beacon signal received by the antenna 13a, a detection circuit, a data demodulation circuit, and the like. The beacon receiving circuit 13 supplies demodulated data to the CPU 11. In addition, the apparatus which transmits a beacon signal is installed in a roadside structure, a utility pole, or the like.

  The CPU 11 calculates current position information (for example, latitude / longitude information) based on the demodulated data. An arithmetic processing program for calculating current position information is stored in a storage unit (not shown). Further, the CPU 11 extracts the advertisement area information included in the SI, and compares the advertisement area information with the current position information. For example, when both pieces of information are latitude / longitude information, it is determined whether the latitude / longitude of the advertisement area information exists in a circular area within a predetermined range centering on the current latitude / longitude. If the latitude / longitude of the advertisement area information is within the predetermined range, it is determined, for example, in which subchannel the advertisement information corresponding to the advertisement area information is present, and the advertisement information packet of this subchannel is extracted. Store in the CM data memory 14.

  In addition, the CPU 11 receives a mode signal from the AV decoder 4. This mode signal changes when a CM flows in broadcasting. Based on the mode signal, the CPU 11 determines whether or not the mode has been switched to CM. When it is determined that the mode has been switched to CM, the CPU 11 reads the advertisement information from the CM data memory 14 and reads the advertisement information from the AV decoder 4 or a data broadcast (not shown). The video is supplied to the decoder, and both or one of video output and audio output of the advertisement information is performed.

  When the digital broadcast reception advertisement information output device described above moves on a mobile vehicle such as a bus, private car, or railcar, the current position information changes every moment, and the viewer is currently located. Regional advertisement information corresponding to the place is presented at the place. In addition, without switching to CM data memory 14, it is also possible to perform processing such as selecting and outputting advertisement information currently being broadcast based on current position information when switching to CM in a broadcast currently being output. It is. That is, it is possible to adopt a configuration (mode) in which the advertisement information selected by comparing the advertisement area information with the current position information is output at the same time as the video / audio. It is also possible to prepare several modes and let the user select them. In addition to the advertisement information output timing being switched to CM, the advertisement information output timing can be a time when a pilot signal (output instruction signal) multiplexed on a digital broadcast wave is received. Alternatively, if the beacon is transmitted only when necessary (for example, transmitted when the time service starts), the beacon signal is also a signal indicating the output timing. In addition to placing advertisement information on the sub-channel, advertisement information can be placed on the sub-audio of the main channel, or advertisement information can be placed on the data broadcast multiplexed on the digital broadcast wave as additional information, and the advertisement information can be extracted. You may do it. Further, if the configuration includes the CM data memory 14, for example, advertisement information broadcasted in the middle of the night is acquired and stored, and stored even if the advertisement information is not broadcast in the daytime. It is possible to output the video / audio output of the advertisement information. In addition to the CM data memory 14 for storing advertisement information placed on digital broadcast waves, a store for storing advertisement information and advertisement area information received by data transfer using transmission waves other than digital broadcast waves or wire. A data memory 15 may be provided, and advertisement information may be selected from the store data memory 15 and output. When the device is mounted on a public vehicle such as a bus or a train, the store data memory 15 may be provided. On the other hand, in the digital broadcast reception advertisement information output device mounted in a private car, the store data memory 15 will be unnecessary. Moreover, although the structure provided with both the GPS receiving circuit 12 and the beacon receiving circuit 13 was shown, the structure provided with either one may be sufficient. In the configuration of FIG. 1, undecoded advertisement information is stored in the CM data memory 14, and the undecoded advertisement information read from the CM data memory 14 is stored in the AV decoder 4 (or a data broadcast decoder (not shown)). However, if the decoded advertisement information is stored in the CM data memory 14, the decoded advertisement information read from the CM data memory 14 can be directly processed by the video processing circuit 5 or the audio processing. The circuit 6 can be supplied. In the configuration of FIG. 1, advertisement information corresponding to the advertisement information may be stored in the CM data memory 14. Even after the advertisement information is acquired, the current position information changes every moment, and when switching to CM, it may be out of the predetermined range. When the advertisement information is read, the current position information at the time of reading is compared with the stored advertisement area information. If the advertisement information is out of the predetermined range, the advertisement information is not output. It may be processed.

  FIG. 2 is a block diagram showing another example of the digital broadcast reception advertisement information output device. 2 includes a remote control transmitter 16, a remote control light receiver 17, an OSD (on-screen display) display circuit 18, an adder 19, and a speech synthesis circuit 20, in addition to the configuration of FIG. The digital broadcast reception advertisement information output device shown in FIG. 2 may be mounted on a private car. Moreover, it is good also as an apparatus united with the car navigation system.

  The OSD display circuit 18 outputs bitmap data based on the character information instructed to be output from the CPU 11 to the adder 19. The adder 19 performs processing for incorporating the bitmap data into the video signal. The OSD display circuit 12 realizes an EPG (Electronic Program Guide) screen display based on the SI received by the CPU 11, an operation guide screen, and a message display for notifying the user that advertisement information exists (for example, , “Displaying advertisement information can be displayed”).

  The voice synthesis circuit 20 has a memory that compresses and stores voice data such as “can output advertisement information”, for example, reads out the voice data from the memory in accordance with a command from the CPU 11, and decompresses the voice data. The voice digital signal thus obtained is supplied to the voice processing circuit 6.

  The remote control transmitter 16 is a transmitter for sending a command to the digital broadcast reception advertisement information output device 30. When a key (not shown) provided on the remote control transmitter 16 is operated, signal light (remote control signal) indicating a command corresponding to the key is transmitted from a light emitting unit (not shown). The remote control light receiver 17 receives the signal light, converts it into an electrical signal, and gives it to the CPU 11.

  In the configuration of FIG. 2, as in the configuration of FIG. 1, when there is advertisement information corresponding to a region, the advertisement information can be automatically output instead of the CM attached to the broadcast. Instead of performing such automatic output, first, a message is output to notify the user that the advertisement information exists. In other words, when the advertisement information corresponding to the area is present in the digital broadcast wave, the CPU 11 uses the OSD display circuit 12 to superimpose a character message such as “output advertisement information” on the display screen of the monitor 9. Or a process of displaying using a part of the screen. Alternatively, or in addition to this, the voice synthesis circuit 20 is used to perform a process of outputting a voice message such as “Advertisement information can be output” from the speaker 10.

  When the user views or listens to the message and operates the remote control transmitter 16 to instruct the device 30 to output advertisement information, the CPU 11 stops the video / audio output of the program and reads it from the CM data memory 14. Video / audio output of advertisement information. Alternatively, the advertisement information is displayed over the video of the program, or only the sound of the program is stopped and the sound of the advertisement information is output.

  The message display is not limited to a text message, and a predetermined mark may be intermittently displayed at a corner of the screen. Further, without using the OSD display circuit 12, the light emitting means such as the LED may be blinked, and the blink may be used as a message notifying the user of the existence of the advertisement information.

  In the configuration of FIGS. 1 and 2, the device 30 selects the advertisement information when the mobile vehicle simply enters the advertising area within a predetermined range, but the traveling direction in addition to the current position of the mobile vehicle. The advertisement information may be selected in consideration of the above.

  FIG. 3 is a block diagram showing another example of the digital broadcast reception advertisement information output device. The configuration of FIG. 3 is a configuration that includes a current position storage unit 21 instead of the GPS reception circuit 12 and the beacon reception circuit 13 in the configuration of FIG. FIG. 3 assumes a digital broadcast reception advertisement information output device placed at home or the like.

  For example, when the user performs auto channel setting based on the area number, the current position storage unit 21 may store the area number as the current position information. The current position information inputted and used may be stored. The current position information is not limited to latitude / longitude information, but can also be character information representing city name information. In addition to the municipality information, a postal code or a telephone number can be used as the current location information. When the advertisement area information placed on the digital broadcast wave is a municipality name or a postal code, the current position information such as the municipality name or the postal code can be given to the CPU 11 as it is. On the other hand, when the advertisement area information placed on the digital broadcast wave is latitude / longitude information, the latitude / longitude information can be given to the CPU 11 by providing a correspondence table of the municipality name, postal code, etc. and latitude / longitude information. As in the configuration of FIGS. 1 and 2, the CPU 11 automatically outputs the advertisement information instead of the CM attached to the broadcast when the advertisement information corresponding to the current position exists, After outputting a message to inform the user that it exists, the advertising information is output by the user's operation.

  In the above description, the case where the terrestrial digital broadcast is viewed has been described as an example. However, the present invention is not limited to this, and the present invention can be applied to the case where the BS digital broadcast or the like is viewed.
