{First embodiment}
The first embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall view of a digital terrestrial radio broadcast system. The terrestrial digital radio broadcast transmitted from the broadcasting station 1 is received by the receiving device 2. The receiving device 2 may be a dedicated terminal that receives terrestrial digital radio broadcasts, or may be a mobile phone having a terrestrial digital radio broadcast reception function.

  As shown in the figure, the receiving device 2 includes an antenna 21, a receiving unit 22, a control unit 23, an operation unit 24, a monitor 25, a speaker 26, a temporary memory 27, and a memory card slot 28. In the figure, a state in which the memory card 29 is inserted into the memory card slot 28 is shown.

  The receiving unit 22 includes a tuner unit 221 and a decoding unit 222. The tuner unit 221 receives a signal of a predetermined channel from the terrestrial digital radio broadcast signal received via the antenna 21 and outputs the signal to the decoding unit 222. The decoding unit 222 demodulates an OFDM (Orthogonal Frequency Division Multiplexing) modulated broadcast signal and decodes a compressed audio signal and the like.

  There are two types of terrestrial digital radio broadcasting: a broadcasting format that uses one segment of the VHF band and a format that uses three segments. The present invention is mainly used when receiving a one-segment broadcasting signal. It is an invention that can be used. That is, in the three-segment digital radio reception, since the bandwidth is wide, the music batch download process and the like can be performed relatively easily. The present invention provides a technique for efficiently storing music even in a one-segment system having a narrow bandwidth.

  The control unit 23 outputs the broadcast signal decoded by the receiving unit 22 from the speaker 26. Thereby, the user can listen to the terrestrial digital radio broadcast. Various additional information is multiplexed in the broadcast signal of digital radio. The control unit 23 displays these additional information on the monitor 25. Thereby, the user can refer to the music information and the like while listening to the radio broadcast.

  FIG. 2 is a diagram showing a recording format of the temporary memory 27. The temporary memory 27 is used as a ring memory. That is, the control unit 23 always records the broadcast data decoded by the receiving unit 22 in the temporary memory 27. First, broadcast data is recorded in the temporary memory 27 in order from the top address, and when the final address is reached, the broadcast data is overwritten and recorded again from the top address. Since the temporary memory 27 needs to temporarily record music data for one song, the temporary memory 27 needs to have a storage size that can record at least one song. For example, an area where broadcast data of about 10 minutes can be recorded is required.

  FIG. 3 is a diagram showing a broadcast signal 50 transmitted from the broadcast station 1. The broadcast signal 50 includes a music signal 51 and a non-music signal 52 on which a DJ voice or CM other than music is broadcast.

  In the present embodiment, the transmission apparatus included in the broadcast station 1 multiplexes the head flag (FlagTM) at the head portion of the music signal 51 and multiplexes the terminal flag (FlagEM) at the terminal portion of the music signal 51. ing. In addition, charging access information (CreditP) is multiplexed in the music signal 51. The control unit 23 records these multiplexed flags and additional information in the temporary memory 27 together. Therefore, by checking the recording positions of the start flag (FlagTM) and the end flag (FlagEM) in the broadcast data recorded in the temporary memory 27, it is possible to specify the start position and end position of the music data. It is.

  As described above, first, the control unit 23 always records the broadcast data decoded by the receiving unit 22 in the temporary memory 27. At this time, the control unit 23 outputs broadcast sound from the speaker 26 while recording broadcast data in the temporary memory 27. Therefore, the user can listen to the terrestrial digital radio broadcast.

  In such a state, when the user intends to save the currently playing music, the user operates the operation unit 24 to give a save instruction. When the control unit 23 receives a storage instruction issued by the user, the control unit 23 performs an overwrite prohibition process on the currently recorded music.

  That is, as shown in FIG. 4, it is specified that the music data is started from the position where the head flag (FlagTM) is recorded, and the address from the recording address of the head flag (FlagTM) to the current recording position is set. Overwriting is prohibited. Further, the overwrite recording is continued until the end flag (FlagEM) of the currently received music is detected. The area from the start flag (FlagTM) to the end flag (FlagEM) is overwritten. Alternatively, after overwriting is performed until the end flag (FlagEM) is detected, the area from the start flag (FlagTM) to the end flag (FlagEM) may be set to prohibit overwriting.

  When the control unit 23 detects the end flag (FlagEM), the control unit 23 then causes the monitor 25 to display a message confirming the user's intention to purchase the music. For example, a message such as “Do you want to buy this song?” Is displayed.

  When an operation for instructing purchase is performed by the user, the operation unit 23 obtains network address information of a server to be accessed for charging processing from the charging access information (CreditP). And as shown in FIG. 1, the control part 23 accesses the WWW server 3 via the internet, and transmits accounting information. When the billing information is transmitted in this way, settlement processing is performed later, and the sales proceeds are distributed to the broadcasting station and the record company.

  When the billing information is transmitted to the WWW server 3, the control unit 23 saves the music data temporarily recorded in the temporary memory 27 in the memory card 29. That is, the data for one song specified by the start flag (FlagTM) and the end flag (FlagEM) is stored in the memory card 29. In this way, the user can store the music data broadcast on the terrestrial digital radio broadcast in the memory card 29. The user can play and enjoy the music stored in the memory card 29 at any time on the receiving device 2. Alternatively, the stored music can be enjoyed by inserting the memory card 29 into another playback device.

  The control unit 23 saves the music data recorded in the temporary memory 27 in the memory card 29 and then cancels overwriting prohibition of the temporary memory 27. Then, the continuous recording of the broadcast data is started again. As described above, the receiving device 2 according to the present embodiment is capable of storing the currently received music in response to the storage instruction given by the user during the music broadcasting while constantly recording the broadcast data. Yes. Since the music part included in the broadcast signal is specified by the start flag (FlagTM) and the end flag (FlagEM), the user can simply save the current flow without performing complicated operations. The stored music can be stored in the memory card 29.

{Second Embodiment}
Next, a second embodiment of the present invention will be described. FIG. 5 is a diagram showing a broadcast signal 50 according to the second embodiment. Also in the second embodiment, the transmission apparatus included in the broadcasting station 1 multiplexes a head flag (FlagMU) at the head of the music signal 51 and multiplexes a terminal flag (FlagME) at the terminal portion of the music signal 51. . In addition, charging access information (CreditP) is multiplexed in the music signal 51.

  FIG. 6 is a diagram showing a broadcast data recording method for the temporary memory 27 by the control unit 23. In the first embodiment, the control unit 23 always records the broadcast data, but in this embodiment, only the music data is recorded in the temporary memory 27.

  That is, the control unit 23 outputs only from the speaker 26 and does not record in the temporary memory 27 while receiving the non-music signal 52 such as DJ sound or CM. Then, the music data is recorded in the temporary memory 27 from the point of time when the multiplexed leading flag (FlagMU) is detected. Then, when the end flag (FlagME) is detected, the recording to the temporary memory 27 is ended. In this way, only the music portion is recorded in the temporary memory 27.

  In such a state, when the user wants to save the currently played music or the music played a little before, the user operates the operation unit 24 to give a save instruction. When the control unit 23 receives a save instruction given by the user, the control unit 23 performs a process of prohibiting overwriting of music data stored in the temporary memory 27 at that time. If the music data is being recorded, the music data is recorded in the temporary memory 27 until the end flag (FlagME) is detected, and overwriting prohibition processing is performed, as in the first embodiment. If the music data is not being recorded, the music data already recorded is overwritten.

  The subsequent processing is the same as in the first embodiment. The user's intention to purchase the music is confirmed, the WWW server 3 is accessed, and the billing information is transmitted. After the charging process, the control unit 23 stores the music data temporarily recorded in the temporary memory 27 in the memory card 29.

  The control unit 23 saves the music data recorded in the temporary memory 27 in the memory card 29 and then cancels overwriting prohibition of the temporary memory 27. Then, it again waits until the head flag (FlagMU) of the music is detected. When the head flag is detected, recording of the music is started.

  In the state where the music data for one song is saved in the temporary memory 27, as described above, when the start flag (FlagMU) of the next song is detected without the user giving a save instruction as described above. Then, recording of the next music is started on the temporary memory 27. That is, as shown in FIG. 6, the temporary memory 27 temporarily stores music data for one song from the head address. Then, when broadcasting of the next music is started without a save instruction, new music data is overwritten from the top address of the temporary memory 27. That is, the user can store the music that has been temporarily recorded in the memory card 29 during the broadcast of the music or after the broadcast ends until the broadcast of the next music starts.

{Third embodiment}
Next, a third embodiment of the present invention will be described. In the third embodiment, as shown in FIG. 7, two temporary memories 27 </ b> A and 27 </ b> B are connected to the control unit 23. Other configurations of the receiving apparatus 2 are the same as those shown in FIG.

  FIG. 8 is a diagram illustrating a broadcast signal 50 according to the third embodiment. Similar to the broadcast signal 50 of the second embodiment, a head flag (FlagMU), a terminal flag (FlagME), and charging access information (CreditP) are multiplexed. In addition, in this embodiment, music information (InfoMU) multiplexed on the broadcast signal 50 is used. That is, the transmitter 1 included in the broadcast station 1 multiplexes the broadcast signal 50 with music information (InfoMU) corresponding to each music. The song information includes information such as song name, artist name, genre name, and song length.

  The recording method in the temporary memories 27A and 27B is basically the same as that in the second embodiment. That is, only the music data is recorded in the temporary memories 27A and 27B.

  First, as shown in FIG. 9, when the first flag (FlagMU) of the first song (MU1) is detected during reception of the broadcast signal 50, the song (MU1) is temporarily recorded in the temporary memory 27A. .

  Next, when the head flag (FlagMU) of the second music piece (MU2) is detected, the second music piece (MU2) is temporarily recorded in the temporary memory 27B. In this way, one piece of music is recorded in each of the temporary memories 27A and 27B. In this state, when the third music is received, the music is alternately overwritten such that the third music is overwritten in the temporary memory 27A and the fourth music is overwritten in the temporary memory 27B. At this time, as shown in FIG. 9, the music information (InfoMU) multiplexed on each music signal 51 is also stored in the temporary memories 27A and 27B together with the music.

  Then, at a certain timing, the user operates the operation unit 24 to give a music storage instruction. The control unit 23 extracts each piece of music information stored in the temporary memories 27A and 27B, and prompts the user to instruct which music to save. FIG. 10 is a diagram showing music information displayed on the monitor 25. In this way, by displaying the respective music information stored in the temporary memories 27A and 27B, the user can refer to the information of the music that can be saved at present.

  That is, in this embodiment, since the two temporary memories 27A and 27B are used, the user selects a song to be saved from two songs that have been broadcast in the past including the current broadcast. It is possible. Of course, the number of temporary memories may be further increased. For example, if four temporary memories are prepared, the user can select a song to be saved from four songs broadcast in the past. In this case, the control unit 23 sequentially records the songs one by one in the first to fourth temporary memories, and when the songs are recorded in all the temporary memories, the song is overwritten again from the first temporary memory. You should do it.

  When the user selects which music is to be saved, the temporary memory in which the selected music is saved is set to prohibit overwriting. Further, the temporary memory in which the music that was not selected for storage by the user is recorded is not overwritten and is released.

  Subsequent processing is the same as in the first and second embodiments. The control unit 23 accesses the WWW server 3 according to the charging access information (CreditP) and executes the charging process. Then, the music selected by the user is stored in the memory card 29. After saving to the memory card 29, the overwriting prohibition of the temporary memory in which the saved music is recorded is released.

{Fourth embodiment}
Next, a fourth embodiment of the present invention will be described. FIG. 11 is a diagram illustrating a broadcast signal 60 according to the fourth embodiment. The broadcast signal 60 includes a music signal 61, a special content signal 62, a DJ signal 63, and a CM signal 64. Each signal is multiplexed with a flag indicating the content of the signal.

  First, in the music signal 61, a head flag (FlagMU) indicating the head of the music and a terminal flag (FlagME) indicating the end are multiplexed. In the special content signal 62, a head flag (FlagTS) indicating the head of the content and a terminal flag (FlagES) indicating the end are multiplexed. A DJ flag (FlagDJ) is multiplexed at the head of the DJ signal 63, and a CM flag (FlagCM) is multiplexed at the head of the CM signal 64.

  In addition, the receiving device 2 according to the fourth embodiment includes four temporary memories 271, 272, 273, and 274, as shown in FIG. Other configurations of the receiving apparatus 2 are the same as those shown in FIG.

  The temporary memory 271 is a memory that records music data, and the temporary memory 272 is a memory that records special contents. These memories are used in the same format as in the second embodiment. That is, only the music data is recorded in the temporary memory 271 using the start flag (FlagMU) and the end flag (FlagME). When the next song is broadcast, the new song is overwritten. Only the special content is recorded in the temporary memory 272 by using the start flag (FlagTS) and the end flag (FlagES). When the next special content is broadcast, the new content is overwritten. The special content is content provided along with music such as a message from an artist. The special contents are not limited to those attached to the music, and various contents may be provided. For example, messages from artists / actors to fans, unusual animal calls, animated character voices, sound effects that can be used as ringtones for mobile phones, and sounds that create an atmosphere can be considered.

  The temporary memory 273 is a memory that records DJ sound, and the temporary memory 274 is a memory that records CM. In these memories, DJ sounds and CMs are recorded in a ring structure. That is, DJ voice and CM are recorded in order from the head address, and when the final address is reached, the voice and CM of DJ are recorded again by returning to the head address. When the control unit 23 detects the DJ flag (FlagDJ) or the CM flag (FlagCM), the control unit 23 records the broadcast data in the temporary memory 273 or the temporary memory 274. Then, when another broadcast data flag is detected, recording to the temporary memory 273 or the temporary memory 274 is stopped. Broadcast data is recorded on the temporary memory 273 or the temporary memory 274 in a ring structure while repeating such recording and stopping.

  When the user performs a save operation while performing such recording, the control unit 23 executes the following processing.

  First, when the user gives an instruction to save music or special content, the same processing as in the second embodiment is executed. After performing the billing process, the music or special content stored in the temporary memory 271 or the temporary memory 272 is stored in the memory card 29.

  It should be noted that a flag indicating whether to pay or not may be multiplexed on the music signal 61 or the special content signal 62. When the pay flag is multiplexed, the address specified by the charge access information (CreditP) is accessed as described above, and the charge process is executed. Then, after executing the billing process, the music or content is stored in the memory card 29. If the free flag is multiplexed, it may be stored in the memory card 29 as it is upon receiving a save instruction.

  When the user instructs to save the DJ sound or CM, the oldest data stored in the temporary memory 273 or the temporary memory 274 to the latest data are prohibited from being overwritten and then saved in the memory card 29. is there. If there is free space in the temporary memories 273 and 274, recording may be performed until the memory is full and then stored in the memory card 29.

  Further, the user can operate the operation unit 24 to give an instruction to listen again to the music or special content temporarily recorded in the temporary memories 271 and 272. In response to this, the control unit 23 reproduces music or special content temporarily recorded in the temporary memories 271 and 272. When the reproduction is completed, the user is caused to determine whether to save or delete. For example, a message such as “Do you want to save the played music now or delete it?” Is displayed on the monitor 25. Then, when the user gives a save instruction, as described above, after overwriting prohibition is set, a billing process is performed, and the music or special content is saved in the memory card 29. On the other hand, when a deletion instruction is issued, the memory in which the music or special content is stored is released.

  As described above, when the music or special content is charged, the charging process may be performed according to the charging access information (CreditP). On the other hand, even if the content is free, the user may desire to cancel the copy-once state. The music signal 61 and the like are set to copy once for copyright protection. In this embodiment, the copy once setting can be canceled by the following mechanism.

  FIG. 13 shows a state in which copy release access information (CponCanP) is multiplexed on the music signal 61. For example, after an instruction to save free music is given, the control unit 23 accesses the server via the Internet in accordance with the address recorded in the copy release access information (CponCanP), and performs a predetermined copy release cancellation. The procedure is performed.

  For example, the right to cancel copy once can be obtained by performing a procedure for answering a questionnaire. When the predetermined procedure is completed, a release key for releasing the copy-once is downloaded to the receiving device 2. Then, the copy-once for the music or special content is canceled, and the music or the like is stored in the memory card 29. After the music or the like is stored in the memory card 29, the storage area of the temporary memory is released as described above.

  This copy cancellation access information (CponCanP) may be included in the broadcast signal 50 of the first to third embodiments. Even in that case, the receiving device 2 can execute the copy-once cancellation procedure by accessing the server.

{Modifications}
In the fourth embodiment, the copy-once release process has been described. However, the copy-once release process may be performed in the accounting process described in the first to third embodiments. That is, in each embodiment, the process of purchasing a music piece by charging processing has been described. However, the purchase procedure may have a plurality of patterns including a copy-once release purchase right.

  One form is the purchase of music while maintaining a copy-once state. That is, the user can store the music on the memory card 29 by the billing process, but cannot copy the music to any other medium.

  Another form includes the purchase of a copy once release key. In this case, the user can also copy the music stored in the memory card 29 to another medium.

  Furthermore, another form is a form in which a copy once release key is purchased together with additional information such as lyrics data and jacket image data. In this form, after the accounting process, the lyrics data and album jacket image data of the stored music are downloaded to the receiving device 2. In this case, the user can enjoy the music stored in the memory card 29 by copying it to another medium or purchase various additional information related to the music.
