When it is determined that the download request has not been received, the CPU 101 determines whether or not the music receiving terminal 2 has performed an end operation (step S15). When it is determined that the end operation has been performed, this processing routine ends. To do.

  If it is determined in step S14 that the download request from the music receiving terminal 2 has been received, the CPU 101 specifies the music requested to be downloaded from the music ID included in the download request. Then, the data of the specified music is read from the music data storage unit 104 for distribution, and the attribute information of the music is read from the music attribute information storage unit 109 and downloaded to the music receiving terminal 2 that requested the download (step). S16).

  Then, the CPU 101 confirms the reception completion depending on whether or not the download data reception completion notification has been received from the music receiving terminal 2 (step S17), and if the reception completion is confirmed, the charging information included in the distribution request or download request is displayed. The accounting processing based on the accounting processing unit 111 is executed (step S18). This is the end of the processing routine in the music distribution server device 1.

  On the other hand, the CPU 201 of the music receiving terminal 2 that has sent the download request in step S5 receives the music data selected and specified downloaded from the music distribution server device 1, and stores the music ID and the music ID in the music data storage unit 208. The song attribute information is received from the song distribution server device 1 and stored in the song attribute information storage unit 109 in association with the song ID (step S6).

  As described above, the attribute information of the music received and stored here is used when the music receiving terminal 2 generates display information of a list menu when a reproduction is requested later.

  Then, the CPU 201 determines whether or not reception of download data has been completed (step S7). When it is determined that reception has not been completed, the CPU 201 returns to step S6 and continues the processing of step S6 until reception is completed.

  If it is determined in step S7 that the download data has been received (step S7), the CPU 201 sends a download data reception completion notification to the music distribution server device 1 (step S8), and then the communication path with the music distribution server device 1 Is cut (step S9), and this processing routine is terminated.

  Next, the music list menu generation process in step S12 of FIG. 8 will be described with reference to FIG.

  First, the CPU 101 refers to the music attribute information storage unit 109 (step S21), reads information on the names of music that can be distributed, and generates character display information (step S22). Next, the CPU 101 reads out the genre information of each song from the song attribute information storage unit 109, and selects an icon corresponding to the genre of each song from a plurality of icons that differ according to the genre difference (step S23).

  Next, tempo information as an example of the music feature amount is read from the music attribute information storage unit 109, and as described above, depending on whether the music is up-tempo or slow-tempo, the genre is determined based on the tempo information. The color gradation of the selected icon is determined in accordance with the difference (step S24).

  Next, the CPU 101 draws and generates music list menu display information according to the character display information generated in step S22 and the icon information determined in steps S23 and S24 (step S25).

  As described above, in the music distribution system of this example, the music receiving terminal 2 displays the music list menu as shown in FIG. 2 on the display screen, so that the user can display not only the music name but also the icons TK, By referring to LS and HL, it is possible to easily select and determine a music piece that is desired to be distributed.

[Reproduction of music stored in music data storage unit 208 in music receiving terminal 2]
When the music receiving terminal 2 receives an instruction to select the playback mode of the music data stored in the music data storage unit 208 through the operation unit 21, the CPU 201 of the music receiving terminal 2 starts the processing routine of FIG.

  First, the CPU 201 controls the display information generation unit 216 for all the songs stored in the music data storage unit 208 to generate display information for a list of display information for music recognition, and generates the generated music recognition data. A list of display information is displayed on the display screen of the display 26 (step S31).

  FIG. 11 is a flowchart showing details of the processing in step S31. That is, the CPU 201 refers to the music attribute information storage unit 212 (step S51), reads information on the music name of the music that is stored in the music data storage unit 208 and can be reproduced, and generates character display information thereof. (Step S52). Next, the CPU 201 reads out the genre information of each song from the song attribute information storage unit 212, and selects an icon corresponding to the genre of each song from a plurality of icons that differ depending on the genre (step S53).

  Next, tempo information as an example of the music feature amount is read from the music attribute information storage unit 212, and as described above, depending on whether the music is uptempo or slow tempo, the genre is determined according to the tempo information. It is determined how to perform the color gradation of the selected icon in accordance with the difference (step S54).

  Next, the CPU 201 refers to the reproduction history storage unit 215 to check whether or not there is a reproduction history for the music for which the display information for recognition is to be created (step S55). When it is determined in step S55 that there is no reproduction history, the CPU 201 follows the character display information generated in step S52 and the icon information determined in steps S53 and S54, and is similar to that shown in FIG. A list of music recognition display information including an icon in which music attribute information is reflected is drawn and generated and displayed on the display screen of the display 26 (step S57).

  When it is determined in step S55 that there is a reproduction history, the CPU 201 determines the characteristics of the reproduction history, in this example, whether it is frequently reproduced in the morning, noon, or night, and the determination result is as follows. A corresponding icon is selected (step S56). Then, the process advances to step S57, and the CPU 201 follows the character display information generated in step S52, the icon information determined in steps S53 and S54, and the icon information determined in step S56 as shown in FIG. A list of display information for recognizing music including an icon reflecting the music attribute information and an icon reflecting the reproduction history is drawn and generated and displayed on the display screen of the display 26 (step S57).

  Then, the CPU 101 of the music receiving terminal 2 monitors which music recognition display information in the list of music recognition display information is selected and determined through the operation unit 21 (step S32 in FIG. 10). If it is determined that the selection determination operation has not been performed, it is determined whether or not a cancel operation has been performed through the operation unit 21 (step S33). If it is determined in step S33 that a cancel operation has been performed, the CPU 201 ends this processing routine.

  If it is determined in step S33 that the cancel operation has not been performed, the CPU 201 returns to the process of step S32 and determines which music recognition display information selection determination operation has been performed.

  When it is determined in step S32 that an operation for selecting and determining display information for recognizing music has been performed, the CPU 201 determines whether or not a music feature amount is stored in the music attribute information storage unit 212 for the music to be played. A determination is made (step S34).

  When it is determined in step S34 that the music feature amount has already been stored, the music ID of the music selected and determined by the selection determining operation is recognized, and the music of the music ID is read from the music data storage unit 208. Reproduction is executed (step S35). That is, the music data read from the music data storage unit 208 is converted into a digital audio signal by the recording encoding / playback decoding unit 209, and the digital audio signal is output from the I / O port 211. Then, the digital audio signal output from the I / O port 211 is converted into an analog audio signal by the D / A converter 23, supplied to the speaker 25 through the amplifier 24, and reproduced as sound.

  Next, the CPU 201 determines whether or not an operation for stopping the reproduction of the music to be reproduced has been performed, or whether or not the reproduction of the music has ended (step S36). When it is determined in step S36 that the operation for stopping the reproduction of the music to be reproduced has not been performed or the reproduction of the music has not ended, the CPU 201 returns to step S35 and continues the reproduction of the music. .

  If it is determined in step S36 that an operation for stopping the reproduction of the music to be reproduced has been performed or the reproduction of the music has been completed, the CPU 201 performs an operation for ending the reproduction mode (an operation for changing to another mode). It is determined whether or not an operation has been performed (step S41). When it is determined that an operation for ending the reproduction mode has been performed, the processing routine for the reproduction mode is terminated.

  If it is determined in step S41 that the playback mode end operation has not been performed, the CPU 201 accepts a playback instruction for the next music through a list of music recognition display information displayed on the screen of the display 26. It is determined whether or not.

  If it is determined in step S34 that the music feature quantity is not stored, the music ID of the music selected and determined by the selection determining operation is recognized, and the music of the music ID is read from the music data storage unit 208. Playback is executed (step S37).

  Then, the CPU 201 controls the music feature quantity calculation unit 213 for the music data being reproduced to perform a music feature quantity calculation process (step S38).

  Next, the CPU 201 determines whether or not an operation for stopping the reproduction of the music to be reproduced has been performed, or whether or not the reproduction of the music has ended (step S39).

  If it is determined in step S39 that the operation for stopping the reproduction of the music to be reproduced has not been performed or the reproduction of the music has not ended, the CPU 201 returns to step S37 and continues the reproduction of the music.

  If it is determined in step S39 that an operation for stopping the reproduction of the music to be reproduced has been performed or the reproduction of the music has ended, the CPU 201 uses the music feature amount calculated by the music feature amount calculation unit 213 as the music In association with the ID, it is written and stored in the music attribute information storage unit 212 (step 40). The stored music feature amount is then reflected in the display of icons in the list of display information for recognition when music reproduction is selected.

  Next, the CPU 201 determines whether or not a playback mode end operation (change operation to another mode) has been performed (step S41). When it is determined that a playback mode end operation has been performed, this playback mode processing routine is performed. Exit.

  If it is determined in step S41 that the reproduction mode end operation has not been performed, the CPU 201 returns to step S32 and proceeds to the next step through the list of music recognition display information displayed on the screen of the display 26. It is determined whether or not a music playback instruction has been received. When a playback instruction is received, the above-described processing is repeated.

[Reproduction from CD22 and recording of music data]
In this embodiment, even when music data is reproduced from the CD 22, if music attribute information is recorded on the CD 22 along with the music data, the music attribute information is used to record the music data on the CD 22. The music list menu is displayed in the same manner as described above.

  Further, at the time of reproducing music data from the CD 22, the music feature quantity calculation unit 213 calculates the music feature quantity of each song and stores it in the music attribute information storage unit 212 in association with the music ID. . Then, when the CD 22 is reproduced from the next time, as a list menu of music recorded on the CD 22, the music characteristic amount stored in the music attribute information storage unit 212 is reflected on the icon. .

  Also, when music data from the CD 22 is stored and recorded in the music data storage unit 208, the music ID and attribute information such as genre and artist name are fetched at the time of recording. In addition to writing to the storage unit 212, the music feature amount calculation unit 213 calculates the music feature amount, and the calculated music feature amount is written to the music attribute information storage unit 212.

  Therefore, the music data from the CD 22 can also display icons in addition to the character information such as the music name in the list of display information for recognition, similarly to the music data downloaded from the music distribution server device 1. This is used when selecting the music to be played.

  When music data from the CD 22 is stored in the music data storage unit 208, if the music ID is obtained from the CD 22, but attribute information such as genre information cannot be obtained, the music ID is obtained via the Internet, for example. Can be used as a searcher to inquire a server device that provides the attribute information providing service, the attribute information can be acquired from the server device, and can be written and stored in the music attribute information storage unit 212.

[Other Embodiments]
In the above-described embodiment, the personal computer as the music receiving terminal 2 receives a music data download from the music distribution server device 1, but the present invention is a portable music storage / playback with a built-in hard disk device. The present invention can also be applied to the form of a system including a device and a personal computer that transfers music data to the music storage / playback device. In that case, the personal computer corresponds to the music transmitting apparatus.

  The personal computer as the music transmission device and the portable music storage / playback device are connected to each other through the communication interface of USB or IEEE1394 standard, and the system is the same as that described above. Similar effects can be obtained.

  In the above-described embodiment, the music feature quantity calculation unit 213 calculates the tempo as the music feature quantity of the music, but the music feature quantity to be calculated is not limited to the tempo. For example, the feature amount of the music may be obtained using MFCC (Mel-Frequency Cepstrum Coefficient).

  Here, Mel-Frequency (mel frequency) is a value created in accordance with “sensitivity of human beings to listen to sound”, and is used to indicate how well the sound can be heard by human ears. Further, Cepstrum (cepstrum) is a result of inverse Fourier transform performed by regarding the logarithm of the power spectrum of the original waveform as a waveform.

That is,
-Take the "amplitude at fixed intervals" of the voice waveform data,
・ Cut out only the necessary part using the Hamming window,
・ Perform discrete Fourier transform ・ Convert the result of discrete Fourier transform to logarithmic representation,
・ Inverse discrete Fourier transform of the logarithmic representation. ・ Processing to extract the waveform generated by inverse Fourier transform at regular intervals. The order of the extracted data is 1D, 2D, 3D ... MFCC is what counts.

  In this case, since the MFCC as the feature quantity extracted from the music signal on the time axis changes along the time axis, an enormous feature quantity is generated in the long-time signal, so the music feature quantity calculation unit 213 Is a mixed normal distribution model (GSM (Gaussian Mixture Modeling)), which is obtained by compressing a feature value using MFCC in the time axis direction and outputting it as a music feature value.

  In the above-described embodiment, an example in which two types of attribute information are reflected in one figure (icon) has been described. However, three or more types of attribute information are reflected in display attributes of one figure. It can also be.

  In addition, as the graphic display attribute, in the above-described embodiment, the color and the gradient thereof have been described as an example. However, the graphic size, the change in the graphic shape, the vibration of the graphic on the display screen, etc. Of course, display attributes can also be used.
