Description

The present invention relates to a content data search device, a content data search method, and a content data search program .

  Many devices that convert audio signals recorded on CD (Compact Disc) albums into audio data files such as MP3 (MPEG-1 Audio Layer-3) and WMA (Windows (registered trademark) Media Audio) It is now possible to acquire music metadata indicating the music name and artist name of each recorded music from a database on the network and embed the metadata into an audio data file as tag data in a predetermined format such as ID3v2. (For this mechanism, see Patent Document 1).

  One database that collects this type of metadata is CDDB (Compact Disc Data Base: Trademark). For example, CDDB related to the operation of Gracenote (trademark) company associates music metadata of music recorded on each CD with TOC (Table Of Contents) data of those CDs. The TOC data is binary data indicating the length of time of each piece of music recorded on the CD until the start of playback, and is stored in a lead-in area secured inside a program area for recording PCM (Pulse Code Modulation) audio data. To be recorded. The combination of the time lengths until the start of reproduction of each piece of music is unique for each album. Therefore, the device that has read the TOC data from the CD album can acquire the song metadata of each song recorded on the CD album from the CDDB in exchange for the transmission of the request including the TOC data. Then, if such music metadata is embedded as tag data in the audio data file obtained from the CD album, it can be referred to during later reproduction or used as a key for searching for a desired audio data file.

The display unit 38 includes, for example, a liquid crystal display, and displays various information on the display based on a signal supplied from the CPU 40.

  The CD drive 39 has a CD loading tray, an optical head, a decoder, and the like. The CD drive 39 supplies the CPU 40 with a PCM (Pulse Code Modulation) audio data signal read from the CD program area and a TOC data signal read from the lead-in area under the control of the CPU 40.

  The CPU 40 executes various programs stored in the EEPROM 41, the flash memory 42, and the hard disk drive 44 while using the SDRAM 43 as a work area. The CPU 40 for executing these programs supplies a digital signal supplied from the CD drive 39 or the tuner 34 to the sound emitting device via the DAC 32 to emit sound, or outputs an audio data file obtained from the digital signal to the hard disk drive. 44, and the audio data file stored in the hard disk drive 44 is transmitted from the Ethernet (registered trademark) controller 35 or the USB controller 36 to an external terminal or personal computer 50. Also do.

  The personal computer 50 supplies a command for operating the audio playback / recording device 30 from its own Ethernet (registered trademark) controller (not shown) to the audio playback / recording device 30, or the audio playback / recording device 30 is a CD. The audio data file generated from is acquired and played. The hardware configuration of the personal computer 50 is the same as that of the music metadata distribution apparatus 10 shown in FIG. 2 except for the storage contents of the hard disk drive. However, the personal computer 50 may have the hardware configuration of the audio playback / recording apparatus 30 and perform the same processing as the audio playback / recording apparatus 30 described above.

  Next, the operation of this embodiment will be described. 5 and 6 are flowcharts showing the characteristic processing of this embodiment. A series of processing shown in this flowchart is started when an instruction to generate an audio data file is given through operation of the operation unit 37 in a state where a CD is loaded in the CD drive 39 of the audio playback / recording apparatus 30.

  When an instruction to generate an audio data file is given, the CPU 40 of the audio playback / recording apparatus 30 acquires PCM audio data of each song read from the program area of the CD loaded in the CD drive 39 (S100). ) TOC data (corresponding to “attribute data”) of each music read from the lead-in area is acquired (S110).

  Subsequently, the CPU 40 transmits an HTTP (Hypertext Transfer Protocol) request including the TOC data acquired in step S110 from the Ethernet (registered trademark) controller 35 to the music metadata distribution apparatus 10 (S120), and then in step S100. In step S130, an audio data file is acquired for each piece of music including the audio data obtained by compressing the PCM audio data obtained in step S1 and the TOC data obtained in step S110.

  Here, it is desirable that the compression of the PCM audio data in step S130 is performed in accordance with an MP3 or WAV data compression algorithm. In that case, the extension of each audio data file acquired in step S130 is MP3 or WAV. Each file name is a character string indicating the recording order on the CD, such as “Track 1” or “Track 2”. Also, the audio data file acquired in step S130 is stored in the SDRAM 43. The transmitted request is transmitted to the music metadata distribution apparatus 10 via the modem 61 and one or a plurality of nodes constituting the Internet communication network 62.

  The CPU 11 of the music metadata distribution apparatus 10 that has received the HTTP request stores the TOC data included in the received request in the RAM 12, and then has a record in the CD database 16 that stores the TOC data in the “TOC” field. It is determined whether or not (S140). When it is determined in step S140 that there is no record storing the TOC data (S140: No), the CPU 11 transmits an HTTP response including a message indicating that to the source of the request (S150). The CPU 40 of the audio playback / recording apparatus 30 that has received an HTTP response including a message indicating that there is no record storing TOC data causes the display unit 38 to display a character string indicating that no song metadata exists (S160). ), The process is terminated.

  When it is determined in step S140 that there is a record storing the TOC data (S140: Yes), the CPU 11 summarizes the data stored in the fields such as “track”, “song name”, and “artist” of the record. Is read for each music piece (S170). For example, if ten songs are recorded on the CD, in this step S170, song metadata corresponding to each of the ten songs is read from the CD database 16.

  CPU11 transmits the HTTP response containing the music metadata read by step S170 to the transmission origin of a request (S180). The transmitted response is transmitted to the audio reproduction / recording apparatus 30 via one or a plurality of nodes of the Internet communication network 62 and the modem 61.

  Receiving the HTTP response, the CPU 40 of the audio playback / recording apparatus 30 embeds each piece of music metadata included in the received response as tag data in each of the audio data files acquired in step S130 (S190). Data formats of tag data that can be embedded in an audio data file such as MP3 include ID3v1 (ID3 Tag Version 1) and ID3v2 (ID3 Tag Version 2). Therefore, in step S190, each piece of music metadata may be converted into these data formats and then embedded in the audio data. The file name of the audio data file is a character string indicating the order of recording on the CD, while the track data forming part of the music metadata is data indicating the track number of each music recorded on the CD. Therefore, it is preferable to associate the two based on the track data and the file name of each audio data.

  The CPU 40 specifies the audio data file of the first music piece, that is, the audio data file in which the track data of the first track is embedded among the audio data files in which the tag data is embedded in step S190 (S200).

  Subsequently, the CPU 40 acquires the song title data embedded as tag data in the audio data file identified in step S200, and sends an HTTP request including the song title data from the Ethernet (registered trademark) controller 35 to the song metadata delivery device 10. (S210). The transmitted request is transmitted to the music metadata distribution apparatus 10 via the modem 61 and one or a plurality of nodes constituting the Internet communication network 62.

  The CPU 11 of the music metadata distribution apparatus 10 that has received the HTTP request determines whether or not the music name data included in the received request is stored in a record different from the record from which the music metadata was read in step S170 ( S220). If the song specified by the song name data is a popular song and is recorded on a plurality of CDs, the determination result in step S220 is “Yes”. Otherwise, the determination result in step S220 is “No”.

  When it is determined in step S220 that the song title data included in the request is stored in another record (S220: Yes), the CPU 11 includes a message indicating that there is another record storing the song title data. An HTTP response is transmitted to the request source (S230). On the other hand, when it is determined in step S220 that the song title data included in the request is not contained in another record (S220: No), the CPU 11 displays a message indicating that there is no other record storing the song title data. The included HTTP response is transmitted to the request source (S240). The transmitted response is transmitted to the audio reproduction / recording apparatus 30 via one or a plurality of nodes of the Internet communication network 62 and the modem 61.

  The CPU 40 of the audio playback / recording apparatus 30 that has received the HTTP response indicates that the message included in the response indicates that there is another record storing the song title data, or indicates that there is no such record. Is determined (S250). When it is determined in step S250 that the message indicates that there is another record storing the song name data (S250: Yes), the CPU 40 embeds the priority data as tag data in the audio data file specified in step S200. (S260). The priority data is data indicating that the music has a high priority. On the other hand, when it is determined in step S250 that the message indicates that there is no other record storing the song title data (S250: No), the CPU 40 proceeds to the next step without executing step S260.

  The CPU 40 determines whether there is an audio data file of the music next to the audio data file specified in step S200 among the audio data files in which the music metadata is embedded in step S190 (S270). When it is determined in step S270 that there is the next audio data file (S270: Yes), the CPU 40 identifies the audio data file (S280), and then performs the processing from step S210 onward for the identified audio data file. Execute. On the other hand, when it is determined in step S270 that there is no next audio data file (S270: No), the CPU 40 displays a character string indicating that the CD ripping is completed on the display unit 38 (S290). The process is terminated. The audio data file obtained by the series of steps described above is stored in the hard disk drive 44 and reproduced by an audio data file reproduction application.

  In the present embodiment described above, when an audio data file is generated by ripping each song of a CD loaded in the CD drive 39 of the audio playback / recording apparatus 30, each of those songs is also recorded on another CD. Judge whether or not. For music recorded on another CD, priority data indicating that the music has a high priority is embedded as tag data in the audio data file. The embedded priority data can be referred to by an audio data file reproduction application, like the song name and artist name tag data. Therefore, by referring to the priority data, it is possible to easily search popular music pieces recorded on a plurality of CDs from a plurality of audio data files stored in the hard disk drive 44. . It is also possible to display a plurality of audio data files searched using the song name and artist name as a key, in order from popular songs recorded on a plurality of CDs.

(Second Embodiment)
A second embodiment of the present invention will be described below with reference to the drawings.

  In the first embodiment, all music recorded on one CD is ripped and priority data is embedded in all or part of the audio data file obtained by the ripping. . On the other hand, in this embodiment, CD ripping and priority data embedding are performed as separate procedures and selected from one or a plurality of audio data files stored in the hard disk drive 44 of the audio playback / recording apparatus 30. Whether or not priority data is embedded is determined for each audio data file.

  The hardware configuration of the music metadata distribution device 10, the audio playback / recording device 30, the personal computer 50, and the modem 61 constituting the data distribution system according to the present embodiment is the same as that of the first embodiment, and the description thereof is omitted. To do.

  Next, the operation of this embodiment will be described. FIG. 7 is a flowchart showing characteristic processing of the present embodiment. A series of processes shown in this flowchart is started when one or a plurality of audio data files are stored in the hard disk drive 44 and any one of them is selected through the operation of the operation unit 37. The audio data file that can be selected is an audio data file that is transmitted from another audio playback / recording apparatus 30 or personal computer 50 or downloaded via a network, and the operation from the operation unit 37 thereafter. Or an audio data file in which tag data of a song name and an artist name is embedded through access to the song metadata distribution device 10.

  When the audio data file is selected, the CPU 40 acquires the song name and artist name embedded as tag data in the audio data file (S300), and then acquires the song name data ("attribute data" of the attribute data) indicating the acquired song name. And an HTTP request including artist name data (corresponding to a part of “attribute data”) indicating the artist name is transmitted from the Ethernet (registered trademark) controller 35 to the music metadata distribution apparatus 10 (corresponding to a part). S310).

  The CPU 11 of the music metadata distribution apparatus 10 that has received the HTTP request stores the song name data included in the received request in the “Song Name” field, and stores the artist name data included in the request in the “Artist” field. It is determined whether or not the record is in the CD database 16 (S320). That is, in this step S320, a search is performed using a combination of a song name and an artist name as a key.

  When it is determined in step S320 that there is no record storing the song name data and artist name data (S320: No), the CPU 11 transmits an HTTP response including a message indicating that to the source of the request ( S330). The CPU 40 of the audio playback / recording apparatus 30 that has received the HTTP response including a message indicating that there is no record storing the song name data and artist name data causes the display unit 38 to display a character string indicating that the song metadata does not exist. (S340), the process is terminated.

  When it is determined in step S320 that there is a record storing the song title data and artist name data (S320: Yes), the CPU 11 stores the song title data stored in the “Song Title” field of the record of another record. It is determined whether or not it is also stored in the “Song Title” field (S350). If the song specified by the song name data is a popular song and is recorded on a plurality of CDs, the determination result in step S350 is “Yes”. Otherwise, the determination result in step S350 is “No”.

  When it is determined in step S350 that the song name data included in the request is stored in another record (S350: Yes), the CPU 11 includes an HTTP including a message indicating that there is another record storing the song name data. The response is transmitted to the request source (S360). On the other hand, when it is determined in step S350 that the song title data included in the request is not stored in another record (S350: No), the CPU 11 displays a message indicating that there is no other record storing the song title data. The HTTP response including the request is transmitted to the request source (S370).

  The CPU 40 of the audio playback / recording apparatus 30 that has received the HTTP response indicates that the message included in the response indicates that there is another record storing the song title data, or indicates that there is no such record. Is determined (S380). When it is determined in step S380 that the message indicates that there is another record storing the song title data (S380: Yes), the CPU 40 embeds priority data as tag data in the audio data file (S390). The process is terminated. On the other hand, when it is determined in step S380 that the message indicates that there is no other record storing the song title data (S380: No), the CPU 40 ends the process without executing step S390.

  In the present embodiment described above, the embedding of priority data in an audio data file is performed as a procedure different from the generation of the audio data file by ripping a CD. Further, instead of the TOC data, the CD database 16 is searched using the song name and artist name embedded as tag data in the audio data file as keys. Therefore, even if the TOC data cannot be obtained from the recording source CD such as an audio data file transmitted from another audio playback / recording apparatus 30 or personal computer 50 or downloaded via the network, the priority data It is possible to determine whether or not there is embedding.

(Third embodiment)
A third embodiment of the present invention will be described below with reference to the drawings.

  In the second embodiment, the CD database 16 is searched using the song name and artist name of the music in the audio data file as keys, and the record to be referenced is specified. On the other hand, in the present embodiment, the file name of the audio data file transmitted from another audio playback / recording device 30 or the personal computer 50 or downloaded via the network is changed to the song name and then the hard disk. Since it is often stored in the drive 44, the CD database 16 is searched by regarding the file name of the audio data file as a key of the song name.

  The hardware configurations of the music metadata distribution device 10, the audio playback / recording device 30, the personal computer 50, and the modem 61 that constitute the data distribution system according to the present embodiment are the same as those of both the above embodiments, and the description thereof is omitted. To do.

  Next, the operation of this embodiment will be described. 8 and 9 are flowcharts showing the characteristic processing of this embodiment. A series of processes shown in this flowchart is started when one or a plurality of audio data files are stored in the hard disk drive 44 and any one of them is selected through the operation of the operation unit 37. Note that the audio data file that can be selected is an audio data file that is transmitted from another audio playback / recording device 30 or personal computer 50 or downloaded via a network, and is operated by an operation from the operation unit 37. This is an audio data file whose file name is changed to the song name. However, unlike the second embodiment, it is not necessary to embed a song name or artist name as tag data in these audio data files.

  When an audio data file is selected, the CPU 40 acquires a character string indicating the file name of the audio data file (S400), and then includes file name data (corresponding to “attribute data”) indicating the acquired character string. An HTTP request is transmitted from the Ethernet (registered trademark) controller 35 to the music metadata distribution apparatus 10 (S410).

  The CPU 11 of the music metadata distribution apparatus 10 that has received the HTTP request has a record in the CD database 16 that stores music name data consisting of the same character string as the file name data included in the received request in the “song name” field. It is determined whether or not (S420). That is, in this step S420, it is considered that the character string indicated by the file name data is the same as the music title, and the search is performed using the character string as a key.

  When it is determined in step S420 that there is no record storing song name data having the same character string as the file name data (S420: No), the CPU 11 sends an HTTP response including a message indicating that to the sender of the request. (S430). The CPU 11 of the audio playback / recording apparatus 30 that has received an HTTP response including a message indicating that there is no record storing song name data having the same character string as the file name data displays a character string indicating that no song metadata exists. 38 (S440), the process is terminated.

  When it is determined in step S420 that there is a record storing song name data having the same character string as the file name data (S420: Yes), the CPU 11 stores the song name data stored in the “song name” field of the record. It is determined whether or not the stored contents of the “artist” field are stored in a plurality of records (S450). That is, in this step S450, it is determined whether or not the music piece having the same music title is a music piece recorded on a CD related to recording by different artists.

  When it is determined in step S450 that the song name data is stored in a plurality of records having different storage contents in the “artist” field (S450: Yes), the CPU 11 stores “artist” in the plurality of records. The artist name data stored in the field is read, and an HTTP response including the artist name data is sent to the request source (S460).

  The CPU 40 of the audio playback / recording apparatus 30 that has received the HTTP response causes the display unit 38 to display an artist selection screen laid out based on a plurality of artist name data included in the response (S470). The artist selection screen is a screen in which a character string “Please select an artist” and a character string indicating a plurality of artist names are arranged. The user who refers to this screen selects one of the artist names through the operation of the operation unit 37.

  When an artist name is selected (S480: Yes), the CPU 40 transmits an HTTP request including artist name data of the selected artist name from the Ethernet (registered trademark) controller 35 to the music metadata distribution apparatus 10. (S490).

  Upon receiving the HTTP request, the CPU 11 of the music metadata distribution apparatus 10 stores the artist name data included in the request in the “artist” field, and the music name having the same character string as the file name data used for the determination in step S420. It is determined whether or not there are a plurality of records storing data in the “Song Title” field (S500). That is, in this step S500, it is determined whether the music of the artist specified by the file name of the audio data file and selected by the user is recorded on a plurality of CDs, or whether such a CD is one. The When it is determined in step S450 that the song name data is not stored in a plurality of records having different storage contents in the “artist” field, the process proceeds from step S460 to step S490 without executing step S490. move on.

  When it is determined in step S500 that there are a plurality of records storing song name data of the same character string (S500: Yes), the CPU 11 transmits an HTTP response including a message indicating that to the sender of the request ( S510). On the other hand, when it is determined in step S500 that there are not a plurality of records storing song title data of the same character string (S500: No), the CPU 11 transmits an HTTP response including a message indicating that to the sender of the request. (S520). The music metadata distribution apparatus 10 that has received the HTTP response performs the same processing as steps S380 and S390 in FIG. 7 (S530 and S540).

  In the present embodiment described above, the character string of the file name of the audio data file is regarded as the same as the song name, and the CD database 16 is searched using the file name as a key. Therefore, it is possible to determine whether or not priority data is embedded even in an audio data file in which tag data of a song name or artist name is not embedded through an operation from the operation unit 37 or access to the song metadata distribution device 10. it can.

(Fourth embodiment)
A fourth embodiment of the present invention will be described below with reference to the drawings.

  In the second embodiment, when there is a record specified from the CD database 16 using the song name and artist name of a song in an audio data file as a key and another record having the same storage content in the “song name” field, priority data is assigned to that record. It is designed to be embedded in an audio data file. On the other hand, in this embodiment, since the song name of a popular song is often the title of the CD itself, the song name of the song in a certain audio data file and the stored contents of the “title” field are the same. When there is another record, the priority data is embedded in the audio data file.

  The hardware configuration of the music metadata distribution device 10, the audio playback / recording device 30, the personal computer 50, and the modem 61, which constitute the data distribution system according to the present embodiment, is the same as that of the above three embodiments, and will be described again. Omit.

  Next, the operation of this embodiment will be described. FIG. 10 is a flowchart showing characteristic processing of this embodiment. A series of processes shown in this flowchart is started when one or a plurality of audio data files are stored in the hard disk drive 44 and any one of them is selected through the operation of the operation unit 37. The audio data file that can be selected is an audio data file that is transmitted from another audio playback / recording apparatus 30 or personal computer 50 or downloaded via a network, and the operation from the operation unit 37 thereafter. Or an audio data file in which tag data of a song name and an artist name is embedded through access to the song metadata distribution device 10.

  When the audio data file is selected, the CPU 40 obtains the song name and artist name embedded as tag data in the audio data file (S600), and then obtains the song name data ("attribute data" of the attribute data) indicating the obtained song name. And an HTTP request including artist name data (corresponding to a part of “attribute data”) indicating the artist name is transmitted from the Ethernet (registered trademark) controller 35 to the music metadata distribution apparatus 10 (corresponding to a part). S610).

  The CPU 11 of the music metadata distribution apparatus 10 that has received the HTTP request stores the song name data included in the received request in the “Song Name” field, and stores the artist name data included in the request in the “Artist” field. It is determined whether or not the record is in the CD database 16 (S620).

  If it is determined in step S620 that there is no record storing the song name data and artist name data (S620: No), the CPU 11 transmits an HTTP response including a message indicating that to the request originator ( S630). The CPU 40 of the audio playback / recording apparatus 30 that has received the HTTP response including a message indicating that there is no record storing the song name data and artist name data causes the display unit 38 to display a character string indicating that the song metadata does not exist. (S640), the process is terminated.

  When it is determined in step S620 that there is a record storing the song title data and artist name data (S620: Yes), the CPU 11 is composed of the same character string as the song title data stored in the “Song Title” field of the record. It is determined whether the title data is stored in the “title” field of the same record or another record (S650). If the song specified by the song name data is a popular song and the song title is the title of the CD itself, the determination result in step S650 is “Yes”. Otherwise, the determination result in step S650 is “No”. It becomes.

  When it is determined in step S650 that title data composed of the same character string as the song title data is stored in the “title” field of the same record or another record (S650: Yes), the CPU 11 An HTTP response including a message indicating that there is a record storing title data of the same character string is transmitted to the source of the request (S660). On the other hand, when it is determined in step S650 that the song title data included in the request is not included in the same or another record (S650: No), the CPU 11 records the title data having the same character string as the song title data. An HTTP response including a message indicating that there is no message is transmitted to the request source (S670). The music metadata distribution apparatus 10 that has received the HTTP response indicates that the message included in the response indicates that there is a record storing title data having the same character string as the music title data, or there is no such record. (S680), and based on the result of the determination, processing similar to step S390 in FIG. 7 is performed (S690).

  According to the present embodiment described above, whether or not priority data is embedded is determined based on whether or not the song name of the song in the audio data file matches the title of the CD on which the song is recorded or another CD. Judgment is made. Even with such a procedure, music suitable for embedding priority data can be specified with high accuracy.

(Fifth embodiment)
A fifth embodiment of the present invention will be described below with reference to the drawings.

  In the second embodiment, when there is a record specified from the CD database 16 using the song name and artist name of a song in an audio data file as a key and another record having the same storage content in the “song name” field, priority data is assigned to that record. It is designed to be embedded in an audio data file. On the other hand, in this embodiment, since the music recorded at the beginning of a single CD of about 1 to 4 songs is often popular, the song name of the audio data file and When the number of track data stored in the record specified from the CD database 16 using the artist name as a key is four or less and the track data of the audio data file indicates “Track 1”, the priority data is Embed it in the audio data file.

  The hardware configuration of the music metadata distribution device 10, the audio playback / recording device 30, the personal computer 50, and the modem 61 constituting the data distribution system according to the present embodiment is the same as that of the above four embodiments, and will be described again. Omit.

  Next, the operation of this embodiment will be described. FIG. 11 is a flowchart showing characteristic processing of the present embodiment. A series of processes shown in this flowchart is started when one or a plurality of audio data files are stored in the hard disk drive 44 and any one of them is selected through the operation of the operation unit 37. The audio data file that can be selected is an audio data file that is transmitted from another audio playback / recording apparatus 30 or personal computer 50 or downloaded via a network, and the operation from the operation unit 37 thereafter. Or an audio data file in which tag data of a song name and an artist name is embedded through access to the song metadata distribution device 10.

  When the audio data file is selected, the same processing as in steps S300 to S320 in FIG. 7 is executed (S700 to S720). In step S720, the song title data (part of “attribute data”) included in the request is executed. If the CPU 11 determines that the record that stores the artist name data (corresponding to a part of the “attribute data”) is not in the CD database 16 (S720: No), the same processing from step S330 to step S340 in FIG. Are executed (S730 to S740).

  If it is determined in step S720 that the CD database 16 has a record storing the song name data and artist name data included in the request (S720: Yes), the CPU 11 stores the track stored in the “track” field of the record. It is determined whether the number of data is 4 or less (S750). If the song specified by the song name data is recorded on a single CD, the determination result in step S750 is “Yes”, otherwise the determination result in step S750 is “No”.

  When it is determined in step S750 that the number of track data stored in the “track” field is four or less (S750: Yes), the CPU 11 stores the track data corresponding to the song title data included in the request as “ It is determined whether or not it indicates “Track 1” (S751). That is, in this step S751, it is determined whether or not the music specified by the music title data is recorded at the beginning of the single CD.

  When it is determined in step S751 that the track data corresponding to the song title data included in the request indicates “Track 1” (S751: Yes), the CPU 11 has four track data corresponding to the song title data. An HTTP response including a message indicating “Track 1” is sent to the source of the request (S760). On the other hand, when it is determined in step S750 that the number of track data stored in the “track” field is greater than four (S750: No), or in step S751, the song name data included in the request When it is determined that the corresponding track data does not indicate “Track 1” (S751: No), the CPU 11 indicates that the track name data and the corresponding track data are not “Track 1” of four or more. An HTTP response including the message is transmitted to the request source (S770). The music metadata distribution apparatus 10 that has received the HTTP response determines whether the message included in the response indicates “Track 1” out of four or more (S780). Based on the result, the same processing as step S390 in FIG. 7 is performed (S790).

  In the present embodiment described above, is the number of track data stored in the “track” field of the record specified from the CD database 16 using the song name and artist name of a song in a certain audio data file as keys? Then, it is determined whether or not the track data of the music of the audio data indicates “Track 1”. Then, priority data is embedded in the audio data file of the music that satisfies both of these requirements. Therefore, priority data can be embedded only in an audio data file of a very popular song (single cut song) recorded at the beginning of a single CD.

(Sixth embodiment)
A sixth embodiment of the present invention will be described below with reference to the drawings.

  In the second embodiment, when there is a record identified from the CD database 16 with the song name and artist name of a song of an audio data file as a key and another record having the same stored content in the “song name” field, that is, the same song Priority data is embedded in the audio data file when there are two or more CDs having recorded. On the other hand, in this embodiment, priority data to be embedded in an audio data file is ranked according to the number of songs recorded on the CD.

  The hardware configuration of the music metadata distribution device 10, the audio playback / recording device 30, the personal computer 50, and the modem 61 constituting the data distribution system according to this embodiment is the same as that of the above five embodiments, and will be described again. Omit.

A series of processes shown in this flowchart is started when one or a plurality of audio data files are stored in the hard disk drive 44 and any one of them is selected through the operation of the operation unit 37. The audio data file that can be selected is an audio data file that is transmitted from another audio playback / recording apparatus 30 or personal computer 50 or downloaded via a network, and the operation from the operation unit 37 thereafter. Or an audio data file in which tag data of a song name and an artist name is embedded through access to the song metadata distribution device 10.

  When an audio data file is selected, processing similar to that in steps S300 to S320 in FIG. 7 is executed (S800 to S820). In step S820, song name data (part of “attribute data”) included in the request is executed. If the CPU 11 determines that the record storing the artist name data (corresponding to a part of the “attribute data”) is not in the CD database 16, the same processing as in steps S330 to S340 in FIG. S830 to S840).

  If it is determined in step S820 that the CD database 16 has a record storing the song title data and artist name data included in the request, the CPU 11 stores the same song title data included in the request in the “Song Title” field. The number of records in the CD database 16 is specified, and an HTTP response including the number is transmitted to the request source (S850).

  The CPU 40 of the audio playback / recording apparatus 30 that has received the HTTP response determines whether the number included in the response is 2 or more, that is, the song name data that is included in the request and transmitted in the two or more records of the CD database 16. It is determined whether it is stored in the “Song Title” field (S860).

  When it is determined in step S860 that the number included in the response is 2 or more (S860: Yes), the CPU 40 determines whether the number is 3 or more, that is, the song title data transmitted by itself included in the request. It is determined whether or not it is stored in the “Song Title” field of three or more records in the CD database 16 (S870).

  When it is determined in step S870 that the number included in the response is 3 or more (S870: Yes), the CPU 11 embeds the priority data of “rank 1” as tag data in the audio data file (S880). When it is determined in step S870 that the number included in the response is not 3 or more (S870: No), the CPU 11 embeds "rank 2" priority data as tag data in the audio data file (S890). The “rank 1” priority data is data indicating that the priority of the music is the highest, and the “rank 2” priority data is data indicating that the priority is the next highest. Further, when it is determined in step S860 that the number included in the response is not 2 or more (S860: No), the CPU 11 ends the process without executing steps S880 and S890.

  In the present embodiment described above, when the number of records storing the same song name data as that of a song in an audio data file is two, priority data of “rank 2” is embedded in the audio data, When the number is three or more, the priority data of “rank 1” is embedded in the audio data. In this way, by embedding priority data with different ranks according to the number of CDs containing songs with the same song title, multiple audio data files searched using song titles and artist names as keys are sorted by priority data rank. Can be displayed.
