FIG. 1 shows the configuration of a first embodiment of an audio providing system to which the present invention is applied. In this audio providing system, for example, a user can immediately (in real time) obtain a song broadcast by a broadcasting station 1 such as an FM (Frequency Modulation) radio broadcasting station.

  That is, various programs are broadcast from the broadcast station 1 according to a normal program. The program data, which is the data of this program, is transmitted to each user via a transmission path 2 that is usually used for broadcasting, such as a terrestrial line or a satellite line.

  On the user (receiver) side, program data from the broadcasting station 1 is received by the receiving device 3. In the receiving device 3, the program data from the broadcast station 1 is output, so that the user can listen to the program.

  Then, when the user listens to the program and desires a song as related data used in the program, the user operates the receiving device 3 to request the song. Then, in the receiving device 3, for example, a communication link with the broadcasting station 1 is established via a public network such as the Internet, an ISDN network or a PSTN network, or a wide area network 4 such as a CATV network. Is transmitted (hereinafter referred to as request information as appropriate). The broadcast station 1 manages, for example, digital audio data (related data) as a song used in a program. When the request information is received from the receiving device 3, the audio as a song corresponding to the request information is recorded. Data is transmitted to the receiving device 3 via the wide area network 4.

  In the receiving device 3, audio data transmitted from the broadcasting station 1 via the wide area network 4 is received and recorded.

  Therefore, when a user listens to a program and likes a song used in the program, the user can easily and immediately obtain the song by simply operating the receiving device 3 in a predetermined manner.

  FIG. 2 shows a configuration example of the broadcasting station 1 of FIG.

  In the broadcasting station 1, for example, text broadcasting is performed together with normal FM broadcasting by FM multiplex broadcasting.

  In other words, the FM multiplex modulation section 11 (program data transmitting means) is supplied with an audio broadcast signal broadcast as an FM broadcast program and character information as a character broadcast program. The unit 11 multiplexes character information with the audio broadcast signal, FM modulates it, and outputs it.

  Here, FIG. 3 shows a multiplexed signal obtained by multiplexing the audio broadcast signal and the character information. The audio broadcast signal is composed of L channel and R channel signals, and a signal L + R or LR is arranged on the low frequency side or high frequency side of the pilot signal arranged in the vicinity of 19 kHz. Character information is arranged on the high frequency side of the signal LR (in the vicinity of 76 kHz in FIG. 3).

  The communication unit 12 (identification information receiving unit) (related data transmitting unit) (information receiving unit) controls communication between the server 13 and the wide area network 4. The server 13 includes a recording medium 16 including a CPU 14, a memory 15, and a hard disk, and manages audio data (related data) as a song used for a program broadcast as an FM broadcast. In other words, the CPU 14 (search means) performs management of reading data from the recording medium 16 and other necessary processing. The memory 15 stores data necessary for the operation of the CPU 14. In a recording medium (storage medium) 16 (storage means), audio data as a song used for a program broadcast as FM broadcast is recorded (stored) in association with identification information for identifying it. Yes.

  In the broadcast station 1 configured as described above, an audio broadcast signal to be broadcast as a program by FM broadcast is input to the FM multiplex modulation unit 11. Further, when the audio broadcast signal is a song, the FM multiplex modulation unit 11 includes identification information for identifying the song (for example, a predetermined code assigned in advance to the song) as character information. Entered. If the audio broadcast signal does not include a song, that is, for example, a disc jockey voice, information to be broadcast as a normal text broadcast is input as text information instead of identification information. The

  In the FM multiplex modulation section 11, identification information as character information is multiplexed on the audio broadcast signal, FM modulated, and output as a multiplexed signal. This multiplexed signal is transmitted via the transmission path 2 as radio waves, for example.

  On the other hand, when there is an access from the receiving device 3 via the wide area network 4, the communication unit 12 establishes a communication link with the receiving device 3 and starts communication control between the receiving device 3 and the server 13. Moreover, the server 13 will perform the process according to the flowchart of FIG. 4, if the communication link with the receiver 3 is established in the communication part 12. FIG.

  That is, first, in step S1, the CPU 14 determines whether or not the request information from the receiving device 3 has been received. If it is determined in step S1 that the request information has not been received, the process returns to step S1. If it is determined in step S1 that the request information has been received, the process proceeds to step S2, and the CPU 14 searches the recording medium 16 for audio data corresponding to the request information. That is, the request information includes identification information as will be described later, and the CPU 14 reads the audio data associated with the identification information from the recording medium 16.

  In step S3, the CPU 14 transfers the audio data read from the recording medium 16 to the communication unit 12 for transmission, and ends the process. In other words, the communication unit 12 transmits the audio data transferred from the CPU 14 to the receiving device 3 that has transmitted the request information via the wide area network 4. After the transmission is completed, the communication unit 12 communicates with the receiving device 3. Disconnect the line between.

  Next, FIG. 5 shows a configuration example of the receiving device 3 of FIG.

  As shown in the figure, the receiving device 3 includes a tuner unit 31 and an information processing unit 32.

  The tuner unit 31 includes a demodulation / separation unit 21, a signal processing unit 22, and an output unit 23.

  The demodulator / separator 21 (program data receiving means) receives radio waves transmitted from the broadcast station 1 and demodulates a multiplexed signal of a predetermined channel among the received signals. Further, the demodulator / separator 21 separates the audio broadcast signal and the character information from the demodulated signal and outputs them to the signal processor 22. The character information is supplied to the I / F unit 24 of the information processing unit 32 in addition to the signal processing unit 22.

  The signal processing unit 22 performs necessary signal processing on the audio broadcast signal and the character information from the demodulation / separation unit 21 and supplies them to the output unit 23. The output unit 23 (output means) includes a speaker 23A and a monitor 23B. Voice and music as an audio broadcast signal are output from the speaker 23A, and characters and figures as character information are displayed on the monitor 23B. It is made like that. The signal processing unit 22 supplies the text information to the output unit 23 only when the text information is information to be subjected to normal text multiplex broadcasting, and does not supply the text information to the output unit 23 when the text information is identification information. It is made like that.

  On the other hand, the information processing unit 32 includes an I / F unit 24, a communication unit 25, a CPU 26, a memory 27, a recording unit 28, a recording medium 29, and an operation unit 30.

  The I / F unit 24 receives character information supplied from the demodulation / separation unit 21 of the tuner unit 31 and supplies it to the CPU 26 when it is identification information. The communication unit 25 (identification information transmission unit) (related data reception unit) (information transmission unit) performs communication control between the CPU 26 and the wide area network 4. The CPU 26 is configured to perform various processes in response to the operation of the operation unit 30 and the like. The memory 27 stores data necessary for the operation of the CPU 26. The recording unit 28 (recording unit) controls data writing to the recording medium 29. The recording medium 29 is, for example, a magneto-optical disk, a magnetic disk, a memory card or other readable / writable recording medium (storage medium), and stores (records) data supplied from the recording unit 28. The recording medium 29 is detachable from the information processing unit 32, for example.

  The operation unit 30 includes, for example, a keyboard 30A and a select button 30B. The keyboard 30A is operated when inputting predetermined information or commands. The select button 30B (operation means) is operated when requesting a song output from the speaker 23A.

  In the receiving apparatus 3 configured as described above, the demodulation / separation unit 21 receives the radio wave transmitted from the broadcast station 1 and demodulates a multiplexed signal of a predetermined channel among the received signals. . Further, the demodulation / separation unit 21 separates the audio broadcast signal and the character information from the demodulated signal, outputs the audio broadcast signal to the signal processing unit 22, and outputs the character information to the signal processing unit 22 and the I / F unit. 24.

  In the signal processing unit 22, signal processing necessary for the audio broadcast signal from the demodulation / separation unit 21 is performed and supplied to the output unit 23. Thereby, the audio | voice and music as an audio broadcast signal are output from the speaker 23A of the output part 23. FIG. Further, in the signal processing unit 22, if the character information from the demodulation / separation unit 21 is not identification information, necessary signal processing is also performed and supplied to the output unit 23. Thereby, the character information is displayed on the monitor 23B of the output unit 23A.

  On the other hand, when the character information from the demodulation / separation unit 21 is identification information, the I / F unit 24 supplies the identification information to the CPU 26.

  In the CPU 26, processing according to the flowchart of FIG. 6 is performed.

  That is, first, in step S11, it is determined whether or not the select button 30B has been operated. If it is determined that the select button 30B has not been operated, the process returns to step S11. If it is determined in step S11 that the select button 30B has been operated, the process proceeds to step S12, and the CPU 26 then selects the audio data corresponding to the identification information supplied from the I / F unit 24, that is, the select button 30B. When is operated, request information for requesting audio data of a song output from the speaker 23A is generated.

  Specifically, the request information pays for requesting audio data, identification information for identifying the audio data (supplied from the I / F unit 24), and consideration (fee) for the audio data. For example, a bank account or credit card number is included. The bank account or credit card number to be included in the request information may be input by operating the keyboard 30A every time the user operates the select button 30B, or by operating the keyboard 30A in advance. The input data may be stored in the memory 27 and the data stored in the memory 27 may be used.

  After the request information is generated, the CPU 26 proceeds to step S13 and controls the communication unit 25 to transmit the request information to the broadcast station 1 via the wide area network 4.

  That is, for example, the identification information includes an access destination to a broadcast station that broadcasts an audio broadcast signal, and the communication unit 25 follows the control of the CPU 26 to determine the access destination (here, the broadcast station 1). A communication link between the network and the network is established via the wide area network 4. Then, the communication unit 25 transmits the request information to the access destination, that is, the broadcast station 1 via the wide area network 4.

  When the request information is transmitted to the broadcast station 1 as described above, as described with reference to FIG. 2, the broadcast station 1 has audio data corresponding to the request information, that is, identification information included in the request information. Audio data corresponding to is retrieved and transmitted.

  Therefore, the CPU 26 proceeds to step S14 after transmitting the request information, and determines whether or not audio data has been transmitted from the broadcast station 1. If it is determined in step S14 that audio data has not been transmitted from the broadcast station 1, the process returns to step S14. If it is determined that audio data has been transmitted from the broadcast station 1, the process proceeds to step S15, and the CPU 26 causes the communication unit 25 to receive the audio data. Further, the CPU 26 transfers the audio data received by the communication unit 25 to the recording unit 28 and records it on the recording medium 29. Then, when all the audio data transmitted from the broadcast station 1 is received and recorded, the process is terminated.

  Therefore, when a user desires a song broadcast in a program, the user can obtain audio data of the song simply by operating the select button 30B while the song is being broadcast.

  In the present embodiment, since the audio data is digital data as described above, it is possible to obtain a song with better sound quality as compared to recording the audio broadcast signal itself broadcast as a radio broadcast. Can do.

  The request information received at the broadcasting station 1 includes the user's bank account or credit card number as described above. In the broadcasting station 1, after transmitting the audio data corresponding to the request information, the fee is withdrawn based on the bank account or the credit card number included in the request information.

  The list of charges for providing audio data can be transmitted from the broadcast station 1 as, for example, text information. In this case, the user can know the charge of the audio data by looking at the list of charges as character information displayed on the monitor 23B.

  Next, FIG. 7 shows a second embodiment of an audio providing system to which the present invention is applied. In the figure, portions corresponding to those in FIG. 1 are denoted by the same reference numerals.

  In this embodiment, the radio wave transmitted from the broadcasting station 1 is received via the transmission path 2 by the receiving device 42 possessed by the user who is moving in the automobile 41 or the like, for example. As a result, the program broadcasted by the broadcasting station 1 is output from the receiving device 42.

  When a user listens to a program output from the receiving device 42 and desires a song used in the program, the user performs a predetermined operation on the receiving device 42. Then, the receiving device 42 establishes a communication link with the broadcast station 1 via the wide area network 4 and transmits request information, similarly to the receiving device 3 of FIG. However, in this case, the request information includes, in addition to the above-described information, specific information (for example, the receiving device 43 provided in the user's house) that should transmit audio data. For example, if the wide area network 4 is a public network, the number of the line to which the receiving device 43 is connected, or if the wide area network 4 is the Internet, the so-called E-mail address of the user of the receiving device 43 ) Is included.

  When receiving the request information from the receiving device 42, the broadcasting station 1 transmits audio data as a song corresponding to the request information via the wide area network 4. However, in this case, the broadcast station 1 transmits the audio data to the terminal (information processing apparatus) specified by the specific information included in the request information, that is, the receiving apparatus 43 in this case.

  In the receiving device 43 at the user's home, audio data transmitted from the broadcasting station 1 via the wide area network 4 is received and recorded.

  Therefore, even when the user is moving by car or the like, when he / she listens to a program and likes a song used in the program, the user can easily and immediately perform the song by operating the receiving device 42 in a predetermined manner. Can be obtained.

  The flowchart of FIG. 8 shows the operation of the server 13 of the broadcast station 1 in the embodiment of FIG. In this case, the configuration of the broadcasting station 1 is basically the same as that shown in FIG.

  In this case, in steps S21 and S22, the same processing as in steps S1 and S2 of FIG. 4 is performed. In step S23, the wide area network 4 is not connected to the receiving device 43 (location) specified by the specifying information included in the request information, but to the receiving device 42 that has transmitted the request information from the communication unit 12 (FIG. 2). The audio data is transmitted via, and the process ends.

  Next, FIG. 9 shows a configuration example of the receiving device 42 of FIG. In the figure, parts that are basically the same as those of the receiving apparatus 3 in FIG. That is, the receiving device 42 includes a tuner unit 31 and an information processing unit 32 (first information processing device), and thus basically has the same configuration as that in FIG. However, in the receiving device 42, the information processing unit 32 is configured without providing the recording unit 28 and the recording medium 28.

In this embodiment, the tuner unit 31 is installed in, for example, the automobile 41 (assumed to be provided in the automobile 41). The information processing unit 32 is, for example, a portable small computer (information processing device) (terminal) (Mobile Computer) that can be connected to the tuner unit 31 via a connection terminal (not shown). As a result, the character information output from the demodulator / separator 21 of the tuner unit 31 can be received by the I / F unit 24.

  Next, the operation will be described with reference to the flowchart of FIG.

  The tuner unit 31 outputs an audio broadcast signal and character information in the same manner as in FIG.

  On the other hand, in the information processing unit 32, in steps S31 and S32, processing similar to that in steps S11 and S12 of FIG. 6 is performed, thereby generating request information. Then, the process proceeds to step S33, and the CPU 26 includes the specific information about the reception device 43 in the request information, and proceeds to step S34. In step S34, the request information is transmitted to the broadcast station 1 in the same manner as in step S13 of FIG. 6, and then the line with the broadcast station 1 is disconnected, and the process ends.

  In this case, request information is transmitted between the receiving device 42 and the wide area network 4 through wireless communication. On the other hand, in the first embodiment, wired communication is basically performed between the receiving device 3 and the wide area network 4. However, also in the first embodiment, transmission of request information can be performed by wireless communication.

  As described above, when the request information including the specific information is transmitted to the broadcast station 1, as described in FIG. 8, the broadcast station 1 transmits the request information to the receiving device 43 specified by the specific information included in the request information. Send audio data.

  Therefore, FIG. 11 shows a configuration example of the receiving device 43 (second information processing device) in FIG. In the figure, parts that are basically the same as those of the receiving apparatus 3 in FIG. That is, the receiving device 43 is configured only from the information processing unit 32. However, in the receiving device 43, the information processing unit 32 is configured without the I / F unit 24 and the operation unit 30.

  Next, the operation will be described with reference to the flowchart of FIG.

  In the receiving device 43, when there is an access from the broadcast station 1 via the wide area network 4, a communication link with the broadcast station 1 (communication unit 12) is established in the communication unit 25. In step S41, it is determined whether audio data has been transmitted from the broadcast station 1. If it is determined in step S41 that no audio data has been transmitted from the broadcast station 1, the process returns to step S41. If it is determined that the audio data has been transmitted from the broadcast station 1, the process proceeds to step S42, and the CPU 26 causes the communication unit 25 to receive the audio data. Further, the CPU 26 transfers the audio data received by the communication unit 25 to the recording unit 28 and records it on the recording medium 29. Then, when all the audio data transmitted from the broadcast station 1 is received and recorded, the process is terminated.

  Therefore, even when the user listens to a song broadcast while moving by the automobile 41 or the like, the user can only select the audio data of the song by operating the select button 30B while the song is being broadcast. It can be obtained.

  In this case, the audio data is received and recorded by the receiving device 43 installed in the user's home. However, the receiving device 43 is configured by providing the recording unit 28 and the recording medium 29, and the receiving device 43 In 43, it is also possible to receive and record audio data.

  In the above, the case where the present invention is applied to an audio providing system that provides a song used in a radio broadcast program has been described. However, the present invention is not limited to a video or a song used in a television broadcast program. It can also be provided when providing video data and audio data. Also in this case, the identification information can be transmitted by, for example, text multiplex broadcasting. That is, in this case, for example, as shown in FIG. 13, the identification information can be transmitted by being superimposed on the vertical blanking period of the television broadcast signal.

  Here, FIG. 13 shows a waveform during a vertical blanking period of a video signal by television broadcasting compliant with the NTSC system. Note that FIG. 13A and FIG. 13B show vertical blanking periods of odd and even fields, respectively.

  Character information (identification information) (denoted as a character signal in FIG. 13) includes the 10th H (line) to 21st H in which no equivalent pulse exists in the vertical blanking period (vertical blanking period), and Although it is possible in principle to superimpose on the 273H to 284H, at present, the characters on the 16th and 21st H, and the 279H and 284H are considered in consideration of the influence of the video signal on the display screen. By superimposing information, character multiplex broadcasting is performed in television broadcasting.
