[0023]
Note that the above-described extension header, padding, and footer can be omitted.
Finally, as shown in FIG. 3C, the playlist 212 stored in the HDD 5 is a list of songs, and describes a playlist name, which is the name of the playlist, and a playlist mode indicating a mode at the time of creating the playlist. You. In the playlist 212, for each song registered in the playlist 212, an audio file path indicating the location of the audio file 213 corresponding to the song on the HDD and the audio file 213 corresponding to the song are stored. Music information such as the track number, title, album name, artist name and genre of the music extracted from the bit rate of the audio data and the tag information of the audio file 213 corresponding to the music is recorded in a standard reproduction order.
[0024]
Now, in such a configuration, the operating system 201 accesses the recording / reproducing processing unit 202 to the playlist 212, the audio file 213, the CDDB 211 stored in the HDD 5, the TOC information recorded in the CD-DA 61, and the audio track. Also, it controls input and output between the display device 2, the input device 3, and the audio output device 4.
[0025]
Hereinafter, the operation of the recording / reproducing processing unit 202 will be described.
When activated, the recording / reproduction control unit 2021 of the recording / reproduction processing unit 202 first displays a control window shown in FIG.
As shown, the control window includes a play button 411, two play speed control buttons 412, a radio button 413 for receiving "random" as a play option, a play list operation area 420, a play list creation area 430, and a "CD". It has a “take in” button 440 and a “search / play” button 450. Note that the play button 411 is replaced with a play stop button while the audio file 213 is being played.
[0026]
The playlist operation area 420 displays a playlist area 421 indicating a list of the playlists 212 recorded in the HDD 5 and information on the audio files 213 registered in the playlist 212 selected in the playlist area. Music area 422 to be played. In the present embodiment, a library list in which all the audio files 213 recorded on the HDD 5 are registered is always generated.
[0027]
Now, when the “CD import” button 440 is operated on the control window by the user, the recording / reproduction control unit causes the recording processing unit 2023 to execute the CD recording process.
In this recording process, the recording processing unit 2023 reads the TOC information from the CD-DA 61, reads a record having the same TOC information as the read TOC information from the CDDB 211, and creates a new folder 210 on the HDD 5. Then, the music pieces of the audio track recorded on the CD-DA 61 are sequentially read out, and compression-encoded to audio data of a predetermined bit rate in accordance with the MP3 compression encoding algorithm is performed. Tag information such as an album name, a genre, and a title of the music based on the CD information of the record of the CDDB 211 read earlier is added, and recorded as an audio file 213 in the folder created earlier, and the recorded audio file 213 is stored in a library. To the play list 212 for use. The registration of the audio file 213 in the library playlist 212 is actually performed based on the location of the audio file 213, the bit rate of the audio data, the tag information of the audio file 213, or the record read from the CDDB 211. This is performed by registering the information of the extracted and created music in the playlist 212 for the library.
[0028]
Returning to FIG. 4A, in the playlist creation area 430 of the control window, an input box 431 for specifying a search item used for searching the audio file 213 recorded on the HDD 5, an input box 432 for specifying a search value, An input box 433 for specifying the number of searches is provided. As a search item, any one of the album name, artist name, and genre of the tag information items is accepted, and a character string that must be included in the tag information item set as the inspection item as the inspection value is included. Accept. If the number of audio files 213 found by the search is found, the number of search ends is received even if the search for all the audio files 213 on the HDD 5 has not been completed. However, when “all songs” is designated as this number, the search is terminated when the investigation on all the audio files 213 on the HDD 5 is completed.
[0029]
Then, when the “create” button 435 in the playlist creation area 430 is operated, the recording / reproduction control unit 2021 executes a playlist creation process.
In the playlist creation process, the tag information of each audio file 213 recorded in the HDD 5 is sequentially examined, and the audio file 213 including the character string in which the item of the tag information set as the search item is set as the search value is searched. The audio files 213 for the number of searches are extracted or all audio files are extracted until the investigation is completed. Then, when the extraction of the audio file 213 is completed, a new playlist 212 is generated in which the value input as the search value is used as the playlist name and the item selected as the search item is used in the playlist mode, and the generated play list is generated. Each extracted audio file 213 is registered in the list 212. Then, the display of the created playlist 212 is added to the playlist area 421 of the control window, and the playlist automatic generation process ends. Note that the registration of the audio file 213 in the newly created playlist 212 is actually performed by extracting the location of the audio file 213, the bit rate of the audio data, and part of the tag information of the audio file 213. This is performed by registering the created music information in the library play list 212.
[0030]
Now, in the control window of FIG. 4A, the “play” button 411 is operated or the “search and play” button 450 is operated with the information that one of the playlists 212 is selected by the user in the playlist area 421. In this case, the recording / reproduction control unit 2021 causes the reproduction processing unit 2022 to execute the following reproduction processing. In addition, when the reproduction stop button is operated, the recording / reproduction control unit 2021 performs processing to end the reproduction processing.
[0031]
FIG. 5 shows the procedure of the reproduction process.
As shown in the drawing, in the playback processing, the playback processing unit 2022 first starts the playback processing by operating the “play” button 411 by the user or starts the playback processing by operating the “search playback” button 450. The process proceeds to step 504 if the playback process has been started by operating the “play” button 411.
[0032]
On the other hand, if the playback process is started by operating the "search playback" button 450, first, a playback song search window is displayed, and an audio file is searched according to the search conditions received in the playback song window (step 526). ).
Here, as shown in FIG. 4B, the playback music search window is provided with an input box 461 for specifying a search item used for searching the audio file 213 recorded on the HDD 5 and an input box 462 for specifying a search value. Have been. Then, the reproduction processing unit 2022 receives any of the album information, the artist name, and the genre among the items of the tag information as the search items, and includes the item of the tag information set as the inspection item as the inspection value. Accept the string that must be. The playback song search window is provided with a check box 463 for accepting "random" as a playback option and a "play" button 464. When the "play" button 464 is operated, a playback process is performed. The unit sequentially examines the tag information of each audio file 213 recorded in the HDD 5 and searches and extracts the audio file 213 in which the item of the tag information set as the search item includes the character string set as the search value. .
[0033]
Returning to FIG. 5, if no audio file has been extracted in the search in step 526, the fact is displayed on the display device (step 534), and the reproduction process ends. On the other hand, when at least one audio file 213 has been extracted, a temporary playlist 212 is generated in which the item selected as the search item is set to the playlist mode, and the extracted audio files 213 are added to the generated temporary playlist 212. Is registered (step 530). Then, the temporary playlist is set as the reproduction target list (step 532), and the process proceeds to step 506.
[0034]
Returning to step 502, if it is determined in step 502 that the reproduction process has been started by operating the "play" button 411, the playlist 212 selected in the playlist area 421 of the control window is to be reproduced. A list is set (step 504), and the process proceeds to step 506.
[0035]
In this step 506, it is checked whether or not the playlist mode of the reproduction target list set as described above is an artist name. If the playlist mode is not an artist name, the process proceeds to step 536, where "random" is set by the user. Check if it is set as a playback option. If "random" is set as a reproduction option, a reproduction execution list is generated in which audio files registered in the reproduction target list are registered in a random order (step 538), and the process proceeds to step 512 and subsequent steps. If "random" is not set as the reproduction option, the process proceeds to step 510, where the reproduction target list is set as the reproduction execution list, and then the process proceeds to step 512 and thereafter.
[0036]
On the other hand, if it is determined in step 506 that the playlist mode of the reproduction target list is the artist name, the process proceeds to step 508 to check whether "random" is set as a reproduction option by the user. If "random" is set as the reproduction option, the process proceeds to step 518; otherwise, the process proceeds to step 510, where the reproduction target list is set as the reproduction execution list, and the process from step 512 onward is performed. move on.
[0037]
On the other hand, in step 518, a plurality of audio files registered in the reproduction target list are classified into groups for each title with reference to the title of the music of each audio file registered in the reproduction target list. That is, the minimum number of groups is set so that audio files of songs having the same title belong to the same group, and audio files of songs having different titles belong to different groups. Then, audio files to be reproduced are selected one by one from each group (step 520). In this selection, for a group including only one audio file 213, the audio file is selected as a reproduction target audio file, and for a group including a plurality of audio files 213, the bit set in the reproduction target playlist is set. This is performed by setting the file having the highest rate as the audio file to be reproduced. When there are a plurality of audio files having the highest bit rate, one of the audio files is set as a reproduction target audio file.
[0038]
Then, a reproduction execution list in which audio files selected from each group are registered in a random order is generated (step 522), and the process proceeds to step 512 and subsequent steps.
In the processing after step 512, each audio file registered in the reproduction execution list generated or set as described above is registered (steps 512, 516, 524) in the order registered in the reproduction execution list (step 524). The audio file 213 is read from the HDD 5, the necessary decoding processing is performed on the audio data in the audio file 213, and the audio data is output to the audio output device 4 to be reproduced (step 514). If so (step 516), the reproduction process ends.
[0039]
The reproduction process has been described above.
According to the above-described playback processing, a playlist as a playback target list (a playlist created by a user in the past by operating a playlist creation button with an artist name as a search item, or a search playback with an artist name specified in search playback) In the case where the playlist mode of the temporary playlist created in step 530 is the artist name, that is, only the audio files of the songs of the same artist are included in the playback target list, and “random” is If it is set as a playback option, the processing of steps 518 to 522 is performed, and an operation is performed so that only one audio file of a song having the same title is included in the playback execution list. Play only once There. Therefore, the same music is not reproduced a plurality of times, and the user is not uncomfortable.
[0040]
By the way, in the above-described reproduction processing, when only the audio files of the music of the same artist are included in the reproduction target list, and only when performing random reproduction, a plurality of audio files of the same music included in the reproduction target list are The music is reproduced only once for the file 213 in the reproduction processing. However, even when the reproduction target list includes a music of a different artist or when the random reproduction is not performed, the reproduction target list is also included. For a plurality of audio files of the same music included in, the music may be reproduced only once in the reproduction processing. If the reproduction target list includes songs of different artists, the difference between the songs in the audio file is determined according to the difference between the artist name and the title.
[0041]
In the above-described reproduction processing, when a plurality of audio files of the same music are included in the reproduction target list, the audio file with the highest bit rate is selected as the audio file 213 to be reproduced. Is configured so that the time length, production date, etc. of the music stored in each audio file can be obtained in the playback processing, and instead of or together with the bit rate, the playback time and The audio file to be reproduced may be selected in consideration of the production date.
[0042]
In the above embodiment, the difference between the songs stored in each audio file 213 is determined based on the difference between the artist and the title. However, the information stored in each audio file is determined using information other than the artist and the title. May be determined. That is, for example, the work number of each music piece is also registered in the CDDB 212, and this work number is included in the tag information of the audio file containing the music piece read out from the CD-DA 61, and the music piece number is determined according to the work number in the tag information. Alternatively, it may be possible to determine the difference between the pieces of music stored in each audio file.
[0043]
The determination of the difference between the music pieces stored in each audio file may be made such that the audio file whose artist and title are completely the same is determined as the audio file 213 storing the same music piece. May be used as the audio file 213 storing the same music. That is, for example, a title in which a character string representing a variation (version) of a song such as "karaoke" or "remix" or a symbol such as "(" or ")" is excluded from the title is identical. The audio file of a song of the same artist having the same may be determined as an audio file storing the same song.
[0044]
【The invention's effect】
As described above, according to the present invention, it is possible to prevent the same music from being reproduced a plurality of times when a plurality of music are automatically and successively reproduced automatically.
