  The present invention relates to a recording apparatus and a recording method for adding fringe information to audio data, and a recording medium.

  In recent years, an audio recording apparatus equipped with a CD (Compact Disc) drive is connected to a memory device such as a portable music player using a HDD (Hard Disc Drive) or a non-volatile memory as a recording medium, and recorded on a CD. Audio recording apparatuses that can directly record audio data that has been compressed and encoded in a predetermined format such as MP3 (MPEG-1 audio layer 3) or AAC (Advanced Audio Coding) into a memory device have become widespread. ing.

  Audio data related information called fringe information such as a song title, album name, and artist name can be added to compressed audio data that has been compression-encoded in a predetermined format. A technique for adding related information to audio data as described above is described in Patent Document 1 below.

JP 2002-245762 A

  By the way, when a memory device is connected to a PC or the like that can be connected to an external network and compressed audio data obtained by compressing and encoding audio data recorded on a CD is recorded in the memory device, the fringe information is transferred to an external server. Can be obtained by accessing and added to the compressed audio data.

  However, in the case of an audio recording apparatus that cannot be connected to an external network or PC, fringe information cannot be automatically acquired and added to compressed audio data. For this reason, conventionally, it is necessary for the user to operate an operation unit or the like provided in the audio recording apparatus and to input fringe information for each audio data, which is troublesome.

  As a method for solving this problem, a method in which a storage unit in which a plurality of fringe information corresponding to audio data is stored in advance is provided in the audio recording apparatus can be considered. Thus, when audio data is recorded from the CD to the memory device, the fringe information corresponding to the recorded audio data can be read from the storage unit, and the fringe information can be added to each audio data. .

  However, the storage unit stores only fringe information related to a CD released before the audio recording device is released. Therefore, when recording audio data recorded on a newly released CD, the fringe information corresponding to the CD is not stored in the storage unit, and there is a problem that the fringe information cannot be added. It was. Further, since it is necessary to provide a storage unit in the audio recording apparatus, there is a problem that the cost increases.

  Therefore, an object of the present invention is to record fringe information without being connected to a network when audio data is recorded on an external recording medium, and to easily add this fringe information to audio data. An apparatus, a recording method, and a recording medium are provided.

  In order to solve the above-described problem, the first invention includes a connection unit to which an external recording medium on which audio data and first TOC information which is information unique to the audio data are recorded is connected; A playback unit that reads the second TOC information from the first disk-shaped recording medium in which the TOC information and the fringe information that is related information of the audio data are associated and recorded, and the first that is recorded on the external recording medium TOC information is compared with the second TOC information recorded on the first disc-shaped recording medium, and the first disc-shaped recording is performed by the reproducing unit when the first and second TOC information matches. And a controller that adds fringe information associated with the second TOC information read from the medium to audio data recorded on an external recording medium. Which is a recording device that.

  The second invention is connected to an external recording medium on which the first TOC information, which is information unique to the audio data and the audio data, is connected, and a fringe, which is related information between the second TOC information and the audio data. The second TOC information is read from the first disc-shaped recording medium recorded in association with the information by the reproducing unit, and the first TOC information recorded on the external recording medium and the first disc-shaped recording The second TOC information read from the first disc-shaped recording medium by the reproduction unit when the first and second TOC information match when compared with the second TOC information recorded on the medium. And adding fringe information associated with the audio data recorded on an external recording medium.

  The third invention is characterized in that TOC information, which is information unique to a disc-shaped recording medium on which audio data is recorded, and fringe information, which is related information of audio data, are recorded in association with each other. Is a recording medium.

  As described above, in the first and second inventions, the audio data and the external recording medium on which the first TOC information, which is information unique to the audio data, is connected, the second TOC information and the audio data are connected. The second TOC information is read from the first disc-shaped recording medium recorded in association with the fringe information, which is related information, and the first TOC information recorded on the external recording medium The second TOC information recorded on the first disk-shaped recording medium is compared, and when the first and second TOC information match, the reproduction unit reads the first TOC information from the first disk-shaped recording medium. Since the fringe information associated with the second TOC information is added to the audio data recorded on the external recording medium, the fringe information is recorded on the external recording medium. It can be easily added to the fringe information to the audio data.

  In the third invention, since the TOC information that is unique to the disc-shaped recording medium on which the audio data is recorded and the fringe information that is related information of the audio data are recorded in association with each other, If there is TOC information that matches the TOC information of the audio data recorded on the recording medium, fringe information can be easily added to the audio data.

  The present invention relates to the second TOC information when the first TOC information recorded on the external recording medium matches the second TOC information recorded on the second disc-shaped recording medium. Since the fringe information is added to the audio data recorded on the external recording medium, the fringe information can be easily added to the audio data even in the recording apparatus 10 that cannot be connected to the network. There is an effect that it can be added.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the recording apparatus 10 includes a central processing unit (CPU) 11 as a control unit, a read only memory (ROM) 12, a random access memory (RAM) 13, a disk drive 14 as a playback unit, and a connection unit. 15, the display unit 16 and the operation unit 17 are connected via a bus 18. Here, a case where a CD (Compact Disc) or a CD-ROM (Compact Disc-Read Only Memory) is used as an attachable / detachable disc-shaped recording medium will be described as an example.

  When an audio CD 30 that is a removable disk-shaped recording medium on which audio data is recorded is loaded, the disk drive 14 reads the audio data from the audio CD 30 and performs predetermined signal processing such as demodulation processing. Then, the disk drive 14 supplies the demodulated audio data to the CPU 11. Further, the disk drive 14 reads out the TOC information indicating the number of music pieces and the reproduction time of the audio data recorded in the innermost peripheral portion of the audio CD 30 and supplies the TOC information to the CPU 11.

  Further, the disc drive 14 reads out the fringe information and supplies it to the CPU 11 when a fringe CD 40 in which information related to audio data called fringe information such as a song title, album name, and artist name is recorded is loaded. .

  The CPU 11 controls each unit connected to the bus 18 using the RAM 13 as a work memory according to a program stored in advance in the ROM 12. In addition, the CPU 11 performs predetermined compression encoding processing on the audio data supplied from the disk drive 14 to generate compressed audio data, and supplies the generated compressed audio data and TOC information to the connection unit 15. For example, MP3 (MPEG-1 audio layer 3) or AAC (Advanced Audio Coding) can be used as compression encoding processing of audio data.

  Further, the CPU 11 converts the fringe information supplied from the disk drive 14 according to the compression encoding format of the compressed audio data recorded in the storage unit 22 of the memory device 20 to be described later, and adds it to the compressed audio data. Specifically, for example, when MP3 is used as the compression encoding format of the compressed audio data, the fringe information is converted into the “ID3 tag” format and added before or after the compressed audio data.

  The connection unit 15 is connected to a connection unit 21 provided in the external memory device 20 by a predetermined connection method, and transmits and receives data by performing communication using a predetermined protocol. As a connection method, for example, USB (Universal Serial Bus) can be used. The connection unit 15 supplies the compressed audio data supplied from the CPU 11 to the memory device 20 via the connection unit 21. The connection unit 15 receives TOC information from the memory device 20 via the connection unit 21 and supplies the TOC information to the CPU 11.

  The display unit 16 uses, for example, an LCD (Liquid Crystal Display), and displays the music number and playback time of the audio CD 30 based on the TOC information of the audio CD 30. Further, the display unit 16 displays the fringe information of the compressed audio data recorded in the storage unit 22 of the memory device 20. The operation unit 17 uses, for example, operators such as dial keys and other keys provided on the panel of the recording apparatus 10, a remote control commander, and the like, and is operated to create a folder for the memory device 20 during recording. The

  The memory device 20 includes a connection unit 21 and a storage unit 22. When the memory device 20 is connected to the recording device 10 via the connection unit 21, the memory device 20 is recognized as a storage device of the recording device 10, and input / output of data recorded in the storage unit 22 is performed by the CPU 11 of the recording device 10. To be controlled.

  The connection unit 21 is connected to the above-described connection unit 15 by a predetermined connection method, and transmits and receives data by performing communication using a predetermined protocol. The storage unit 22 uses, for example, an HDD (Hard Disc Drive) or a nonvolatile memory as a recording medium, and records compressed audio data and TOC information supplied from the recording device 10 via the connection unit 21. The compressed audio data and the TOC information recorded in the storage unit 22 are not limited to this example, and may be recorded by another recording device, for example. The storage unit 22 supplies the recorded TOC information to the connection unit 21 based on the control of the CPU 11 of the recording apparatus 10.

  The memory device 20 may be, for example, a portable music player that can reproduce compressed audio data by itself as long as it can be controlled by the CPU 11 as a storage device when connected to the recording apparatus 10.

  Next, the fringe CD40 will be described. On the fringe CD 40, fringe information, which is related information of audio data, is recorded for a plurality of audio CDs 30. As the fringe information, as shown in FIG. 2, for example, the album name, artist name, and title of the audio CD 30 are described. The fringe information is associated with the TOC information of each audio CD 30.

  The item “TOC information” indicates the TOC information of the corresponding audio CD 30. The TOC information is information unique to the audio CD 30, and describes information such as the song number and playback time of the audio data recorded on the audio CD 30. In the item “album name”, the album name of the audio CD 30 is described. In the item “artist name”, an artist name such as a performer of the audio CD 30 is described. The item “title” describes the name of each piece of audio data recorded on the audio CD 30.

  Note that items described as fringe information are not limited to this example, and for example, items such as a genre of audio data, a production year, and comments on audio data may be further provided. Further, the fringe information is not limited to the character information as described above, and for example, image and video information such as a jacket image or commercial video of the audio CD 30 may be recorded in association with the TOC information.

  By the way, the fringe information recorded on the fringe CD 40 is information associated with the TOC information of the audio CD released at a certain time. Therefore, no fringe information is recorded for audio CDs released after a certain point. Therefore, for example, when a new audio CD is recorded, there may be a case where fringe information cannot be added to the audio data by using the fringe CD 40 currently owned. Therefore, in such a case, it is possible to cope with a new audio CD by updating the fringe CD 40 to obtain a new fringe CD.

  As a method for updating the fringe CD 40, for example, a method of periodically providing the latest fringe CD from a fringe information provider can be considered. In this case, for example, the user can obtain a customer by registering and receiving a new fringe CD.

  As another method for updating the fringe CD, for example, fringe information can be downloaded via an external network, and a CD-R (CD-Recordable) or CD-RW (CD-ReWritable) can be recorded. A method of recording on a recording medium is conceivable. In this case, for example, a PC that can be connected to an external network such as the Internet and has a disk drive capable of recording data on a CD-R or CD-RW is prepared, and fringe information is downloaded from the server. Then, the downloaded fringe information is recorded on a CD-R or CD-RW to produce a fringe CD.

  By preparing a plurality of fringe CDs in this way, it is possible to deal with more audio CDs such as newly released audio CDs.

  Next, a method for recording compressed audio data from the audio CD 30 to the memory device 20 and adding fringe information to the recorded compressed audio data will be described. First, the recording device 10 and the memory device 20 are connected, and the memory device 20 is recognized as a storage device of the recording device 10.

  When recording the audio data of the audio CD 30 in the memory device 20, the user operates the operation unit 17 to create a folder classified for each artist in the storage unit 22. Further, the user creates a folder classified for each album in a folder for each artist. As described above, it is preferable that the folder structure for recording the audio data has a hierarchical structure for each artist and each album so that the classification of the compressed audio data becomes clear when recording from a plurality of audio CDs.

  The folder for recording audio data is not limited to this example, and may be automatically created with a predetermined folder name, for example.

  When the audio CD 30 is loaded in the disk drive 14, the disk drive 14 reads audio data from the audio CD 30 based on the control of the CPU 11 and performs predetermined signal processing such as demodulation processing. Then, the demodulated audio data is supplied to the CPU 11. Further, the disk drive 14 reads the TOC information from the audio CD 30 and supplies it to the CPU 11.

  The CPU 11 performs compression encoding processing on the audio data supplied from the disk drive 14 to generate compressed audio data. The generated compressed audio data and the TOC information supplied from the disk drive 14 are supplied to the memory device 20.

  The memory device 20 records the compressed audio data and TOC information supplied from the recording device 10 in a predetermined folder created by the user. An example of the file structure in the storage unit 22 in this case is shown in FIG. 3A. In this case, the fringe data is not added to the album name for the audio data and the title of each compressed audio data, so for example, temporary names such as “Title # 1,” “Title # 2,” and so on are provided. Added.

  Next, when the fringe CD 40 is mounted on the disk drive 14, the drive 14 recognizes that it is the fringe CD 40 based on the TOC information of the mounted disk-shaped recording medium. Then, the TOC information is read from the storage unit 22 of the memory device 20 and supplied to the CPU 11. The CPU 11 compares the TOC information supplied from the memory device 20 with the TOC information of the audio CD 30 recorded on the fringe CD 40, and reads the fringe information associated with the matching TOC information from the fringe CD 40. The drive 14 is controlled. The disk drive 14 reads the fringe information from the fringe CD 40 based on the control by the CPU 11 and supplies it to the CPU 11.

  The CPU 11 converts the fringe information supplied from the disk drive 14 into a predetermined format according to the format of the compressed audio data recorded in the storage unit 22, and the compressed audio data recorded in the storage unit 22 of the memory device 20. Append to By doing so, the file structure in the storage unit 22 is as shown in FIG. 3B, and the album name based on the fringe information and the title of each compressed audio data are added to each folder and file name.

  Next, in the recording apparatus 10 according to the embodiment of the present invention, the processing flow when adding fringe information to the audio data recorded in the memory device 20 is described with reference to the flowchart shown in FIG. This will be described in detail. In the following, it is assumed that processing is performed by the CPU 11 unless otherwise specified.

  In step S <b> 14, the CPU 11 compares the TOC information received from the memory device 20 with the TOC information recorded on the fringe CD 40 and reads from the memory device 20 among the plurality of TOC information recorded on the fringe CD 40. It is determined whether there is TOC information that matches the TOC information. If the TOC information read from the memory device 20 is recorded on the fringe CD 40 as a result of the comparison, the process proceeds to step S15.

  In step S <b> 15, the fringe information associated with the TOC information read from the memory device 20 is read from the fringe CD 40 and supplied to the CPU 11. In step S <b> 16, the CPU 11 converts the fringe information read from the fringe CD 40 according to the compression encoding format of the compressed audio data recorded in the memory device 20, and converts it into the compressed audio data recorded in the storage unit 22. The series of processing is completed.

  On the other hand, if the TOC information that matches the TOC information read from the memory device 20 is not recorded on the fringe CD 40 in step S14, the process proceeds to step S17. In step S17, it is determined whether or not to install a fringe CD different from the fringe CD 40 attached to the disk drive 14. At this time, for example, it is preferable to display on the display unit 16 of the recording apparatus 10 so as to notify the user that the fringe CD 40 is to be replaced.

  In the case of mounting another fringe CD, the user takes out the fringe CD mounted on the disk drive 14, mounts another fringe CD, and the process returns to step S12. When no other fringe CD is mounted, the fringe information is not added to the compressed audio data recorded in the memory device 20, and the series of processes ends.
