  Next, a specific operation of the mobile communication terminal 1 having the above configuration will be described.

  First, music reproduction processing executed by the mobile communication terminal 1 in the present embodiment will be described with reference to the drawings. FIG. 5 is a flowchart showing details of the music reproduction process.

  When the user operates the cross cursor key, the enter button, or the like of the operation unit 7 to select “reproduce music” from the “menu list” displayed on the display unit 6, the music reproduction process shown in FIG. 5 is started. . When this music reproduction process is started, the system control unit 10 first refers to the entire reproduction list 96 stored in the nonvolatile memory (EEPROM: Electrically Erasable Programmable Read Only Memory) of the music storage management unit 9. The artist name and the song title are specified and displayed as a list on the display unit 6.

  First, with reference to the list of artist names and song names displayed on the display unit 6, when the user operates the cross cursor key or the enter button on the operation unit 7 to specify the music to be played (step S101; Yes). The system control unit 10 reads the reproduction list 96 in which the designated music is stored, and selects the file name of the designated music from the read reproduction list 96 (step S102).

  At this time, the system control unit 10 reads the value of the favorite flag DF corresponding to the file name selected in the process of step S102 from the favorite music list 95 shown in FIG. Is determined. Here, if the value of the favorite flag is “0”, that is, if the music specified in the process of step S101 is not registered in the favorites, “Do you want to register this music in favorites?” Is displayed on the display unit 6.

  When the user selects “Register to Favorites” by operating the cross-shaped cursor key, the enter button or the like of the operation unit 7 in accordance with the selection screen displayed on the display unit 6 (step S103; No), the above By setting the value of the favorite flag read in the process of “1” to “1”, the music designated in the process of step S101 is registered as a favorite (step S104). On the other hand, when the value of the favorite flag is “1” or when the user selects not to perform “favorite registration” (step S103; Yes), the process proceeds to step S105, and step S104 is performed. Skip the process.

  Thereafter, when the user operates the cross cursor key, the enter button, or the like of the operation unit 7 to instruct the reproduction of the music designated in the process of step S101 (step S105; Yes), the reproduction list 96 is referred to. The music number (song number) specified in the process of step S101 is specified, and the specified music number “M” is set as the counter initial value in the playback music number counter provided in the RAM of the system control unit 10. (Step S106).

  On the other hand, when the user designates “play” by operating the cross-cursor key, the determination button, or the like of the operation unit 7 without designating the music to be played (step S101; No) (step S107; Yes). Then, a random number is extracted from a random counter provided in the RAM of the system control unit 10, and a random reproduction playlist 96 as shown in FIG. 4 is created and registered in the random reproduction playlist 96. Of the file names of the music, the file name of the first music is selected as the file name of the music to be played (step S108). Since the music selected in step S108 is the first music, “1” is set as the counter initial value in the reproduction music number counter (step S109).

  When the process of step S106 or S109 described above is completed, the number of reproductions corresponding to the file name of the music selected in the process of step S102 or S108 is read from the favorite music list 95, and "+1" is added. The number of reproductions is updated by setting the number of times and resetting it in the music list 95 (step S110). And it is discriminate | determined whether the reproduction | regeneration frequency after update became larger than the frequency | count of reproduction (setting frequency) preset as a threshold value (step S111).

  Here, when the number of times of reproduction after the update is larger than the set number of times (step S111; Yes), the frequency corresponding to the file name of the music selected in the process of step S102 or S108 from the newly entered music list 95 is repeated. The value of the reproduction flag FF is read, and it is determined whether or not the value of the frequent reproduction flag FF is “0” (step S112). At this time, if the value of the frequent reproduction flag FF is “0” (step S112; Yes), the value of the frequent reproduction flag FF is set to “register as a favorite” for the music selected in the process of step S102 or S108. Update to “1” (step S113). On the other hand, if it is “1” (step S112; No), it is determined that “registration as a favorite” has already been performed, and the process proceeds to step S114. To skip.

  On the other hand, if it is determined in the above-described determination processing in step S111 that the updated number of reproductions is equal to or less than the set number (step S111; No), the condition to be “registered as a favorite” has not yet been established. As a thing, it progresses to the process of step S114 and skips the process of step S112 and S113.

  Thereafter, the system control unit 10 refers to the reproduction list 96, specifies a file name corresponding to the count value (music number) in the reproduction music number counter, and stores the MP3 file having the specified file name as a music storage management unit. 9 is read from the non-volatile memory (EEPROM) 9 and supplied to the music playback unit 14 to start playback of the music and to start measurement of playback time using a time counter provided in the RAM (step S114).

  After that, by sequentially checking whether the count value in the time counter has reached the count value corresponding to the playback time of the music specified from the MP3 file, it is determined whether or not the playback of one music has ended. (Step S115). If it is determined that the reproduction of one piece of music has been completed (step S115; Yes), the time counter is reset to return the count value in the time counter to the initial value “0” (step S116), and the reproduced music piece The count value in the number counter is incremented by “+1” (step S117).

  And it is discriminate | determined whether the count value after addition reached the maximum value (maximum number) of the music number in the reproduction | regeneration list 96 (step S118), and when not reaching the maximum number (step S118; No) ), The process returns to step S110. On the other hand, if the count value after the addition reaches the maximum number (step S118; Yes), the count value in the reproduction music number counter is set to the initial value “1” (step S119), and then the process proceeds to step S110. And return. Thereby, reproduction of the next music is started.

On the other hand, when a reason for interrupting music playback occurs, such as when an incoming call from another mobile communication terminal is received before the playback of one music is completed (step S115; No, step S120; Yes). Then, a music reproduction interruption / resumption process described later is executed (step S121). Further, when the user operates the cross cursor key, the enter button, or the like of the operation unit 7 to instruct “end of reproduction” during reproduction of the music (Step S115; No, Step S120; No, Step S122; Yes), this music reproduction process is terminated.
The above processing is the music reproduction processing executed by the mobile communication terminal 1.

  Next, the music reproduction interruption / resumption process in step S121 in FIG. 5 will be described with reference to the drawings. FIG. 6 is a flowchart showing details of the processing content of the music reproduction interruption / resumption processing.

  First, when it is determined by the determination process in step S120 described above that a music reproduction interruption cause has occurred, the system control unit 10 interrupts reading of the MP3 file from the nonvolatile memory (EEPROM) of the music storage management unit 9. Then, the reproduction of the music is interrupted (step S201), and the measurement of the interruption time by the interruption time counter provided in the RAM is started (step S202). Next, the count value (music number) in the reproduction music number counter is written in the reproduction music file number register 91 as an interrupted music file number (step S203). For example, when a reason for interruption of music reproduction occurs during reproduction of the fifth music piece in the reproduction list 96, the reproduction music file number register 91 stores “reproduction music file number” as “reproduction music file number” as shown in FIG. 5 "is set.

  Subsequently, the system control unit 10 acquires the count value in the time counter (step S204), and calculates a played ratio (%) indicating what percentage of the interrupted music pieces have been played (step S205). Specifically, the played ratio is calculated by dividing the count value in the time counter acquired in the process of step S204 by the count value corresponding to the playback time of the music specified from the MP3 file.

  Then, by referring to the playback progress determination table shown in FIG. 7B stored in the ROM of the system control unit 10, the playback progress number corresponding to the playback completed ratio calculated in the process of step S205. PN is determined (step S206), and the determined reproduction progress number PN is written in the current reproduction progress number register 92 (step S207). For example, when the playback ratio calculated in the process of step S205 is 33%, “4” is set as the playback progress number PN in the current playback progress number register 92 as shown in FIG. The

Thereafter, when the reason for interrupting the music playback is resolved, such as when the call with another mobile communication terminal is terminated (step S208; Yes), a playback restart process described later is executed (step S209).
The above processing is the music reproduction interruption / resumption processing executed in step S121.

  Next, the reproduction restart process in step S209 will be described with reference to the drawings. FIG. 8 is a flowchart showing details of the playback restart process, and FIG. 9 is a timing chart for explaining the playback restart process.

  First, the system control unit 10 acquires the count value in the interruption time counter (step S301), resets the interruption time counter (step S302), and compares the acquired count value with a predetermined threshold value, thereby reproducing the music piece. It is determined whether or not has been interrupted for a predetermined time or more (step S303). When the music interruption time PT is within the above-mentioned predetermined time (step S303; No), a selection screen such as “Do you want to resume playing music?” Is displayed on the display unit 6.

  In response to the selection screen displayed on the display unit 6, when the user operates the cross cursor key, the enter button, or the like on the operation unit 7 to instruct “resume playback” (step S 304; Yes), the reproduced music The interrupted music file number set in the process of step S203 in FIG. 6 is acquired from the file number register 91 (step S305), and the count value (reproduced time count value) in the time counter is acquired and converted into the restart time. (Step S306).

  Then, the system control unit 10 specifies the MP3 file having the file name corresponding to the interrupted music file number acquired in the process of step S305, and reads the data from the specified MP3 file in the process of step S306. By starting from the address corresponding to the restart time converted in this way, as shown in FIG. 9A, the reproduction of the music is resumed from the point where it was interrupted in step S201 in FIG. 6 (step S307). At this time, the measurement of the reproduction time by the time counter is resumed. Thereafter, the system control unit 10 proceeds to the process of step S115 in FIG.

  On the other hand, if the music interruption time PT exceeds the above-mentioned predetermined time (step S303; Yes), the interruption music file number set in the process of step S203 in FIG. Obtain (step S308).

  Subsequently, the playback list 96 is referred to, the file name corresponding to the interrupted music file number acquired in the process of step S308 is specified, and the newly stored music list 95 is referred to, and the specified file name is set. By checking the corresponding frequent reproduction flag FF and favorite flag DF, it is determined whether or not the song having this file name is registered in “favorites” (steps S309 and S310).

  Here, when the value of at least one of the frequent reproduction flag FF and the favorite flag DF is “1” (step S309; Yes, step S310; Yes), the process of step S201 in FIG. 6 is performed. Assuming that the interrupted music is registered in “favorites”, after resetting the time counter, the process proceeds to step S114 in FIG. 5 to reproduce this music from the beginning as shown in FIG. 9B. .

  On the other hand, when the values of the frequent reproduction flag FF and the favorite flag DF are both “0” (step S309; No, step S310; No), the music piece interrupted in the process of step S201 in FIG. 6 is acquired from the current playback progress number register 92 (step S311), and the playback progress number is registered from the progress reference number register 93. A reference value BN is acquired (step S312).

  Then, the playback progress number PN acquired in the process of step S311 is compared with the playback progress reference value BN acquired in the process of step S312 (step S313). If it is less than or equal to the reference value BN (step S313; No), after resetting the time counter, the process proceeds to step S114 in FIG. 5, thereby making step S201 in FIG. 6 as shown in FIG. 9B. The music that was interrupted by the process is played from the beginning.

On the other hand, if the playback progress number PN exceeds the playback progress reference value BN (step S313; Yes), after resetting the time counter, the process proceeds to step S117 in FIG. Playback of the music next to the music that was interrupted in step S201 is started. In the example shown in FIG. 7A, “4” is set as the playback progress number PN in the current playback progress number register 92, and “3” is set as the playback progress reference BN in the progress reference number register 93. Therefore, it is determined Yes in the process of step S313, and as shown in FIG. 9C, the reproduction of the music next to the interrupted music is started.
The above processing is the reproduction resumption processing executed in step S208.

  As described above, according to the mobile communication terminal 1 of the present embodiment, when a music is interrupted for a predetermined time or longer, after the reason for the interruption is resolved, the reproduction of the music is resumed from the interruption time, and the interruption time is If it is within the predetermined time and the interrupted music is registered as “favorite”, the interrupted music is replayed from the beginning after the reason for the interruption is resolved. On the other hand, when the interrupted music is not registered as a “favorite” and the ratio of the replayed music does not exceed a predetermined threshold, the same as when the “favorite” is registered, Replaying is started, and when the played ratio exceeds a predetermined threshold, playback of the music specified next to the music suspended in the play list 96 is started.

  In this way, if a predetermined percentage or more of the interrupted songs have already been played, after the reason for the interruption has been resolved, skip the interrupted songs and start playback from the next song, Even if there are a plurality of interruptions in the meantime, it is possible to avoid the situation where the same music piece is repeatedly played, thereby reducing user discomfort.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation and application are possible. Hereinafter, modifications of the above-described embodiment applicable to the present invention will be described.
