The play list switching unit 3 is a part for switching the play list currently being played back to a different play list based on an instruction from the input determining unit 2. Which playback list is switched to is not uniquely determined, and may be performed based on a predetermined switching criterion.
For example, as will be described later, when a plurality of playlists are set to have a predetermined layer relationship, the playlist is switched to another playlist set at the same level as the currently played playlist. May be.

Further, when the play list is switched, when the fast-forward button 12 is input, the stored arrangement order may be switched to the next play list among the plurality of play lists in the same hierarchy.
Furthermore, when the rewind button 13 is input, it is only necessary to switch to a playlist having the previous arrangement order among a plurality of playlists in the same hierarchy.

The music switching unit 4 is a part that switches the currently played music to another music based on an instruction from the input determination unit 2. Which music to switch to is not uniquely determined.
For example, as will be described later, the registration order stored in the music data 22 is referred to, and when the fast-forward button 12 is input, the registration order may be switched to the next music.
When the rewind button 13 is input, the registration order may be switched to the previous music piece. Alternatively, when there is a play list to which the currently played music belongs, the next song or the previous song in the play list may be switched in correspondence with the fast forward button 12 or the rewind button 13.

The reproduction processing unit 5 is a part that reproduces content. In particular, based on an instruction from the input determination unit 2, the playback start process for the currently selected song, the pause process for the currently playing song, the fast-forward process for the currently playing song, or the currently playing song This is the part that performs rewinding processing.

The function of each functional block is realized by causing the CPU to organically operate various hardware based on a program stored in a ROM or the like.

The audio output unit 6 is a part that outputs sound such as music to the outside. For example, a speaker provided in the apparatus main body is used. However, when a wired earphone with a remote control or a wireless headset is connected, the speaker of the earphone or headset becomes the audio output unit.
The display unit 7 is a part for displaying the content itself, displaying a display screen necessary for inputting information and selecting a function, and an LCD, an organic EL display, or the like is used.

The storage unit 20 is a part for storing information necessary for executing the functions of the information processing apparatus of the present invention, a program, etc., and a storage such as a semiconductor storage element such as a ROM, RAM, flash memory, HDD, SSD, etc. A storage medium such as a device or a DVD or CD is used.
The program may be supplied to the computer via an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit the program.
The storage unit 20 mainly stores play list data 21, music data 22, long press setting time 23, user selection information 24, and playing information 25. However, in addition to this, information such as a plurality of contents other than music may be stored.

  The reproduction list data 21 stores one or a plurality of reproduction lists, and the reproduction list is a list in which contents having common characteristics among a plurality of contents are registered as one group. One reproduction list is a list that is created based on characteristics such as feature items and classification items of a song and includes one or more song names. Further, when the playlist is created in a hierarchy structure, the playlist data 21 includes information indicating the hierarchy relationship between the playlists.

FIG. 3 shows an explanatory diagram of an embodiment of the reproduction list data 21.
FIG. 3A shows data indicating the hierarchical relationship of the five reproduction lists (A, A1, A2, B, B1).
FIG. 3C is a diagram showing the hierarchical relationship shown in FIG. For example, the playlist A and the playlist B belong to the first hierarchy (layer 1), and these playlists indicate that there is no upper hierarchy playlist.

Further, the playlists A1 and A2 belong to the second hierarchy (layer 2), and the playlist on the upper hierarchy one above these playlists is the playlist A.
The reproduction list B1 belongs to the second hierarchy (layer 2), and the reproduction list in the upper hierarchy is the reproduction list B.

FIG. 3B shows an example of the contents of music included in each playlist.
Here, it is shown that the reproduction list A1 includes two music pieces (101, 102), and the reproduction lists A2 and B1 include the music piece 103 and the music piece 104, respectively.
As described above, when the process of switching to the playlist of the same hierarchy (layer) is performed, for example, when the playlist currently being played back is A1 of layer 2, the playlist is switched to playlist A2 of the same hierarchy (layer 2). .

FIG. 4 is an explanatory diagram of an embodiment of music data stored in the storage unit.
The music data 22 in FIG. 4A stores information for each music piece.
One piece of music data includes, for example, a song name (or song identification information), a file specifying the song itself, and a reproduction list to which the song belongs.

In FIG. 4, the song having the song name “101” has the file “aa101.mp3”, and belongs to the reproduction list A1.
When the user does not select the play list and directly selects one song, for example, when the song name “101” is selected and being played and the fast-forward button 12 is pressed shortly, The music selection operation is performed, and the music “102” registered after “101” in the music data 22 is selected and reproduced.

The long press setting time 23 means a time for determining whether the input operation is “short press” or “long press” when the fast forward button 12 or the rewind button 13 is input.
In the case of FIG. 4B, when the long press setting time 23 is set in advance as 5 seconds and the operation button is continuously pressed down for 5 seconds or more, the input operation of the button is determined as the long press operation. To do.
Conversely, if the duration of the pressed state (the time during which the input operation is performed) is shorter than 5 seconds, it is determined that the operation is a short press operation.
The long press setting time is not limited to 5 seconds, but may be set in advance to another time, or the user may change the setting to a unique time.

The user selection information 24 means information stored in association with the selection input operation when the user selects a music or the like to be viewed on the apparatus main body.
Generally, when a desired music is selected, there are a case where an individual music is directly selected and input, and a case where a reproduction list including the music is selected.
Further, when selecting a playlist, there are a case where a playlist prepared in advance by default is selected, and a case where a playlist itself created by the user is selected.

Therefore, when the user directly selects and inputs each piece of music, the user selection information 24 stores information on the selected music (music information).
Further, when the user selects and inputs a playlist, the selected playlist information (playlist information) is stored in the user selection information 24.
FIG. 4C shows a case where the reproduction list “A1” is selected, and FIG. 4D shows a case where the song “102” is selected.

Depending on the contents stored in the user selection information 24, event processing to be executed varies as described later. For example, when content (music) information is stored in the user selection information 24, a process for changing the reproduction state of the content (music) currently being reproduced is executed.
The process for changing the reproduction state is, for example, either a process for fast-forwarding the currently reproduced content (music piece) or a process for rewinding the currently reproduced content (music piece).

  Here, in addition to storing information for specifying a playlist or a song in the user selection information 24, when the user performs a selection operation to perform a song playback process, the user selects the playlist or the song Only information (for example, a selection flag having a value of 0 or 1) for discriminating whether or not has been selected may be stored.

The in-reproduction information 25 stores information on the music currently being reproduced.
As shown in FIG. 4 (e), the playback information 25 includes information specifying the music being played (for example, “102”), and a play list to which the music being played belongs (for example, “A1”). Is included.
When the music being reproduced is registered in duplicate in a plurality of reproduction lists, all of the registered reproduction lists may be stored. Based on the contents of the in-reproduction information 25, the music to be reproduced next and the reproduction list can be determined.

<Execution event for user input operation>
FIG. 2 is an explanatory diagram of an embodiment of an execution event for a user input operation.
Here, the user input operation is assumed to operate the fast-forward button 12 and the rewind button 13 among the operation buttons 11 attached to the earphone.
The execution event indicates a process to be executed when a predetermined event condition is satisfied.
The event condition indicates a condition for executing the execution event. The type of the operation button, the type of input time of the operation button, and the user selection stored by the user's selection input operation at the start of playback. Information 24 is included.

The operation button indicates whether the operated button is the “fast forward button 12” or the “rewind button 13”. Specific input operations using these operation buttons include an operation of long-pressing the fast-forward button or an operation of long-pressing the rewind button.
“Input time” indicates whether the time during which the input of the operated button is continued is “long press” or “short press”.
Whether the input time is “long press” or “short press” is determined by comparing the actual input duration time with the long press set time 23 described above.

As described above, the user selection information 24 stores either reproduction list information for specifying a reproduction list or music information for specifying a music piece.
Here, for example, in FIG. 1, “playlist information” is stored in the user selection information 24, and when the fast-forward button 12 is operated for a long time, a playlist including the currently played music is changed to another in the same hierarchy. A process of switching to the next playlist in the playlist is executed. Thereafter, the reproduction processing unit 5 reproduces predetermined content (music) included in the switched reproduction list.
The next playlist, for example, means a playlist that is one level lower than the current playlist based on the registration order of the playlist data shown in FIG.

Similarly, when “play list information” is stored as the user selection information 24, No. 2, when the rewind button 13 is pressed for a long time, a process of switching to the previous playlist in the same hierarchy is executed.
No. 3, “music information” is stored as the user selection information 24, and when the fast-forward button 12 is operated for a long time, a process of fast-forwarding the same music being reproduced is executed.
No. 4, “music information” is stored as the user selection information 24, and when the rewind button 13 is pressed for a long time, a process of rewinding the same music currently being played back is executed.

No. 5 to No. Up to 8 shows an execution event when the button is “short-pressed”, and in either case, a process of switching the music being played back to another music is performed. That is, when a short press operation is performed on the fast-forward button or the rewind button, the content (music) being played is switched to another content and played.
For example, no. 5, “play list information” is stored as the user selection information 24, and when the fast-forward button 12 is pressed for a short time, the music to be played is switched so as to play the next music in the same play list.
No. 6, “play list information” is stored as the user selection information 24, and when the rewind button 13 is pressed for a short time, the music to be played is switched to play the previous music in the same play list.

No. 7, “music information” is stored as the user selection information 24, and when the fast-forward button 12 is operated for a short time, the music to be reproduced is switched so that the next music existing in the same hierarchy is reproduced.
No. 8, “music information” is stored as the user selection information 24, and when the rewind button 13 is pressed for a short time, the music to be reproduced is switched so that the previous music existing in the same hierarchy is reproduced.

As described above, by combining the information stored in the user selection information 24 and the user's operation content of a predetermined operation button, three types of processing, that is, playlist switching processing, music switching processing, Either fast forward or rewind processing of the same music can be executed.
By using a wired earphone with a remote control or a button attached to a wireless device as an operation button, there is no need to add an operation button, and it is not necessary to take out the device body from a pocket or the like, and any of the above three types can be easily performed. Such processing can be performed, and the operation burden on the user can be reduced.

<Switching process during playback>
FIG. 5 shows a flowchart of an embodiment of the music switching process executed by the information processing apparatus of the present invention.
Here, after the user starts playback of a predetermined song by performing an input operation for selecting a song or a playlist using the input unit 1, the user presses the fast-forward button 12 attached to the earphone with remote control or A case will be described in which the rewind button 13 is operated to switch the music to be played, to switch the play list to be played, and to fast forward or rewind the music being played.

In step S <b> 1, it is confirmed whether or not the user has performed an input operation using the input unit 1.
When an input operation is performed by the user, the input determination unit 2 determines what is instructed by the input operation.

In step S2, the input determination unit 2 checks whether or not the content instructed by the input operation is the start of reproduction.
If reproduction is started, the process proceeds to step S3. If not, the process returns to step S1.
However, if the reproduction is not started and there is a processing content associated with the input operation, the processing content may be executed without returning to step S1.

In this invention, when the user inputs an instruction to start playback, the user performs an operation of selecting a desired piece of music or an operation of selecting a desired play list before performing the input operation. Shall.
It may be temporarily stored in the storage unit 20 whether the music or the reproduction list is selected by this selection operation.

In step S <b> 3, when one piece of music is selected, the reproduction processing unit 5 starts reproduction of the music and outputs audio from the audio output unit 6.
Here, the playback processing unit 5 stores the information of the music that has started playback (the music being played back and the list being played back) in the playing information 25.

In step S4, the input determination unit 2 confirms whether the user has selected a music piece or a reproduction list before inputting a reproduction start instruction.
When the music is selected, the music information is stored in the user selection information 24 as shown in FIG.
When the playlist is selected, the playlist information is stored in the user selection information 24 as shown in FIG.

In step S5, the input determination unit 2 checks whether the user has performed a new input operation.
Here, not only the input operation of the device main body but also the input operation of the button attached to the earphone with remote control or the input operation of the button provided in the device capable of wireless communication with the device main body is checked.
The following flow shows a case where the “fast forward button 12” or “rewind button 13” attached to the earphone with remote control or the wireless device is input.

If there is no input operation in the input check in step S5, step S5 is looped.
Further, when it is confirmed that an input operation has been performed, a timer is started, and for example, after an input operation for depressing a button is started, an input time until the button is released is measured.

In step S6, it is checked whether the input user operation is for the fast-forward button 12 or the rewind button 13, and if it is either button, the process proceeds to step S7. Proceed to step S12.
In step S12, when the input user operation is an input indicating the end of reproduction, the process ends.
Otherwise, the process returns to step S5 as shown in FIG. Or although not shown in figure, when it is the input for performing another function, you may perform the function.

In step S7, it is checked whether or not the input operation performed by the user is a long press operation. Here, for example, as described above, it is determined whether the measured input time is longer or shorter than the long press setting time 23.
If the measured input time is longer than the long press setting time 23, it is determined that a long press operation is being performed, and if it is shorter than the long press setting time 23, it is determined that a short press operation has been performed.
When the long press operation is performed, the process proceeds to step S9, and when the short press operation is performed, the process proceeds to step S8.

In step S8, since the short press operation of the fast forward button 12 or the rewind button 13 has been performed, the music being played is switched to another music and played.
In the reproduction process here, the above-described No. in FIG. 5 to No. Execute any event up to 8.

For example, no. When the event condition 5 is satisfied and the fast-forward button 12 is pressed for a short time, the music (next song) arranged next to the currently played music is played out of the music in the same playlist. Switch as follows.
No. When the event condition of 8 is satisfied, when the rewind button 13 is pressed for a short time, switching is performed so as to play the previous song of the same hierarchy that was played immediately before the currently played song.
After step S8, the process returns to step S5, and the same processing as described above is repeated.

In step S9, it is checked whether the information stored in the user selection information 24 is reproduction list information or music information.
In the case of reproduction list information, the process proceeds to step S10, and in the case of music information, the process proceeds to step S11.

In step S10, since the play list has been selected, the play list currently being played is switched to another play list in the same hierarchy, and the music included in the play list after the change is played.
Here, the music to be played back may be any music included in the playlist after switching, or may be music placed at the top. Further, the order of music to be played by the user may be set in advance.

The processing executed in this step S10 is No. 1 in FIG. 1 and No. This corresponds to an execution event corresponding to any one of the event conditions.
For example, when the play list information is stored in the user selection information 24 and the fast-forward button 12 is operated for a long time, no. Since the event condition of 1 is satisfied, the playlist is switched to the playlist (next playlist) arranged next to the playlist being played out of the playlists in the same hierarchy as the currently played playlist.

In addition, when the playlist information is stored in the user selection information 24 and the rewind button 13 is operated for a long time, no. Since the condition 2 is satisfied, the playlist is switched to a playlist (previous playlist) arranged immediately before the playlist being played out of the playlists in the same hierarchy as the currently played playlist.
Then, it returns to step S5 and repeats the same process.

In step S11, since the music has been selected, in response to the long press operation of the fast forward button 12 or the rewind button 13, the music currently being reproduced is fast forwarded or rewinded.
The processing executed in this step S11 is No. 1 in FIG. 3 and no. 4 corresponds to an execution event corresponding to any one of the event conditions.
The fast-forwarding or rewinding process is performed only for the time during which the user holds down the fast-forward button 12 or the rewind button 13, and the process may be terminated when released.
Then, it returns to step S5 and repeats the same process.

  As described above, in the series of processing from step S5 to S12, the content of the user selection information stored by the user's selection operation at the start of reproduction and the long press or short press of a predetermined operation button attached to the earphone Depending on the combination with the operation, any of the music switching process, playlist switching process, fast-forwarding and rewinding of the music being played can be easily performed without taking out the device body from the pocket, etc. The burden of user input operations can be reduced.

Also, at the start of playback, the content of the user selection information 24 is determined by the user's selection operation. For example, when priority is given to fast-forwarding or rewinding the same music over switching of the playlist, the user starts playback. Sometimes, an operation of selecting one piece of music may be performed.
For example, if the music to be played is not just music, but a recorded audio teaching material for language learning, etc., you can select the music and then press and hold the fast-forward button or the rewind button Fast forward and rewind are possible.

In addition, when priority is given to switching playlists over playback fast forward and rewind of the same song, for example, when as many songs as possible are to be played back, the user selects one playlist at the start of playback. Just do it.
As a result, before listening to all the music pieces included in the selected play list, it is possible to switch to another play list and continue playing other music pieces.
