Description

  The present invention relates to a technique for controlling playback of a track playback device.

  The track playback device plays back a track such as a song, sound, or audio book in accordance with its own play list. The track playback device may be connected to a speaker alone, or connected to another device such as a car navigation device, and playback may be performed using an amplifier and speaker that the other device has or is connected to. Sometimes it is done.

  The track playback device has functions such as shuffle playback, random playback, and the like, in addition to the normal playback method of playing tracks for each album, by switching the order of the tracks.

  However, for example, when the same track is included in different albums, it is inconvenient for the user if these same tracks are played back in succession as a result of shuffle playback or random playback. In addition, a very short track or the like recorded in an album for connecting the preceding and following tracks does not make sense even if it is played by shuffle playback or random playback. These problems are only examples, but when the reproduction is not performed in the normal order such as the shuffle reproduction or the random reproduction as described above, a specific problem that impedes the convenience for the user occurs.

  With respect to this problem, in Patent Document 1 (paragraph 0024), when music data stored in a storage medium is randomly played by an in-vehicle audio device, a playlist is recreated so that the music data does not overlap, and random playback is performed. Therefore, it is proposed that the same music data is not repeatedly reproduced.

JP 2008-217871 A

  When the music stored in the storage medium is reproduced as in the technique of Patent Document 1, since the in-vehicle audio apparatus itself can have a reproduction list, it is easy to prevent the same music data from being repeatedly reproduced. However, when a track playback device is connected to an in-vehicle audio device for playback, the track playback device has a playlist, so the order of playback cannot be freely rearranged on the in-vehicle audio device side, and means for correcting Absent.

  An object of the present invention is to improve the convenience of a playback function of a track playback device while using a playback list of the track playback device.

  A playback control device according to the present invention is a playback control device that makes a track-up request to a track playback device that plays back tracks in accordance with the playback order described in the playback list. A track information acquisition unit that acquires track information of a target track that is a track that is being played or is scheduled to be played back, and a first track or a track that should be tracked up based on the track information of the target track acquired by the track information acquisition unit A determination unit that performs a track-up determination to determine that the second track should not be increased, and a reproduction control unit that issues a track-up request for the first track to the track reproduction device.

  The car navigation device 2A includes an information acquisition unit 21, a determination unit 22, and a reproduction control unit 23. The information acquisition unit 21 acquires track information of the target track, which is a track being reproduced or scheduled to be reproduced, from the track reproduction device 1. Based on the track information of the target track acquired by the information acquisition unit 21, the determination unit 22 performs a track-up determination that determines that the target track is the first track that should be tracked up or the second track that should not be tracked up. The playback control unit 23 sends a track-up request for the first track to the track playback device 1. According to the above configuration, since it is possible to automatically track up a track that is determined not to be reproduced based on the track information, convenience for the user is improved.

<B. Second Embodiment>
<B-1. Configuration>
FIG. 2 is a block diagram showing a configuration of the second embodiment of the present invention. In Embodiment 2, the playback control device of the present invention will be described as a car navigation device, but the playback control device of the present invention is not limited to a car navigation device.

  The track playback device 1 is a portable terminal such as a smartphone having an audio track playback function, and includes a storage unit 11, a playback unit 12, and an operation reception unit 13. The storage unit 11 stores audio track data, audio track information, and a reproduction list. In the present specification, the term “audio track” is used as a term encompassing recorded audio, etc. in addition to music, audio books, audio track data (hereinafter simply referred to as “track data”), audio Information such as the track name, artist name, and album name of the track is referred to as audio track information (hereinafter simply “track information”).

  The reproduction unit 12 acquires track data from the storage unit 11 and reproduces the track data according to the reproduction list. The track data reproduced by the reproduction unit 12 is transmitted to the reproduction control unit 23 of the car navigation device 2B, and is output as sound from the speaker 32 connected to the car navigation device 2B. That is, the track reproducing device 1 is connected to the car navigation device 2B and reproduces music. The track information of the audio track reproduced by the reproducing unit 12 is also transmitted to the car navigation device 2B.

  The operation accepting unit 13 is an input interface that accepts a user operation, and is realized as, for example, a “play button”, a “tune feed button”, or the like.

  The car navigation device 2B includes an information acquisition unit 21, a determination unit 22, a reproduction control unit 23, and a reproduction history storage unit 24. Although not shown in FIG. 2, the communication between the track reproducing device 1 and the car navigation device 2B is performed by a communication I / F such as a Bluetooth (registered trademark) standard or a USB (Universal Serial Bus) standard. In FIG. 2, the amplifier 31 and the speaker 32 are illustrated as different configurations from the car navigation device 2B, but the car navigation device 2B may include these.

  When the playback unit 12 of the track playback device 1 plays back a track, the playback data (track data) is sent from the playback unit 12 to the information acquisition unit 21. The track data is sent from the information acquisition unit 21 to the reproduction control unit 23, further amplified by the amplifier 31, and output as audio from the speaker 32.

  The information acquisition unit 21 acquires the track information of the track being reproduced or the track to be reproduced from the track reproduction device 1 among the track information recorded in the reproduction list of the track reproduction device 1. Since the track being reproduced or the track scheduled to be reproduced is a target for track-up determination by the car navigation device 2B, these tracks are also referred to as “target tracks” in this specification.

  The information acquisition unit 21 stores the track information reproduced by the reproduction unit 12 in the reproduction history storage unit 24. Accordingly, the reproduction history storage unit 24 stores track information of a track (second track) reproduced in the past.

  FIG. 3 is a hardware configuration diagram of the car navigation device 2B shown in FIG. The car navigation device 2B includes a processor 41, a memory 42, a communication I / F 43, and a storage medium 44. The reproduction history storage unit 24 is realized by a storage medium 44 such as an HDD (Hard Disk Drive). The determination unit 22 and the reproduction control unit 23 are realized as a function of the processor 41 when a processor 41 such as a CPU (Control Processing Unit) executes a software program stored in a memory 42 such as a RAM (Random Access Memory). . However, these may be realized in cooperation with a plurality of processors 41, for example.

  The software program stored in the memory 42 is connected to the track playback device 1 that plays back tracks according to a play list that describes the playback order of tracks, or is played back on a computer (processor 41) that incorporates the track playback device 1. A reproduction control program for making a track-up request to the apparatus 1, and having the computer (processor 41) send track information of a target track, which is a track being reproduced or scheduled to be reproduced, from the track reproduction apparatus. For obtaining a target track as a first track that should be tracked up or a second track that should not be tracked up based on the track information of the target track, and for making a track-up request for the first track to the track playback device , Playback control A gram.

<B-2. Operation>
Next, the operation of the car navigation apparatus 2B will be described along the flowchart of FIG.

  When a track is played back by the playback unit 12 (step S1), track information of the track currently being played back is transmitted from the track playback device 1 to the information acquisition unit 21. The information acquisition unit 21 stores the track information of the track being reproduced in the reproduction history storage unit 24 (step S2). Since the track information of the track being played is stored and accumulated in the playback history storage unit 24 at any time, the track information of the tracks played in the past can be referred to by the playback history storage unit 24.

  Next, the information acquisition unit 21 acquires information on the next track (next track information) (step S3). The next track information indicates a track scheduled to be reproduced next to the currently reproduced track in the reproduction list. However, depending on the standard or specification of the track reproducing apparatus 1, there is a case where track information other than the currently reproduced track cannot be output to the outside. In such a case, the information acquisition unit 21 cannot acquire the next track information, but the flow in FIG. 4 will be described on the assumption that the next track information can be acquired. That is, in the flow of FIG. 4, the target track that is subject to track-up determination is the track that is scheduled to be played. The flow when the information acquisition unit 21 cannot acquire the next track information will be described later with reference to FIG.

  The next track information is sent from the information acquisition unit 21 to the determination unit 22, and the determination unit 22 performs track up determination of the next track based on the next track information (step S4). Here, the determination unit 22 refers to the reproduction history storage unit 24, and in the track information stored in the reproduction history storage unit 24, the next track information (track information of the undetermined target track) acquired in step S3 and Determine if there is a match. If there is a match, the next track (target track) is determined to be the first track to be tracked up, and the process returns to step S3 again to acquire track information to be reproduced next. Accordingly, the same track as the already reproduced track is determined as the first track.

  Note that the matching of the track information in this step may be a state in which all of the track information matches. Alternatively, when the track information includes a track name, an artist name, and an album name, a state in which a part of the track information matches, such as determining a track having a different album name but the same track name as the first track. May be the coincidence of the track information in this step.

  If the track information that matches the track information acquired in step S4 is not stored in the reproduction history storage unit 24, the determination unit 22 determines that the next track (target track) is the second track that should not be tracked up. Then, the number of times of track up corresponding to the number of first tracks continuously existing from the next track of the track currently being reproduced (second track) is determined (step S5).

  Specifically, when it is determined that the next track of the currently playing track is the second track, the number of track ups is 0. When only the next track of the currently playing track is determined as the first track, the number of track ups is 2 When n first tracks including the next track of the track currently being reproduced are consecutive, the number of times of track up is (n + 1). The determination unit 22 transmits the track-up count determined in this way to the reproduction control unit 23.

  If the number of times of track up is 0 (step S6: Yes), the process returns to step S2, and when the next track is reproduced, the track information of the track (second track) is stored in the reproduction history storage unit 24.

  When the number of track ups is not 0 (step S6: No), the playback control unit 23 determines whether or not the playback of the currently playing track is just before the end (step S7). If it is not immediately before the end, the process waits until the end (step S7: No).

  At the timing just before the end, the reproduction control unit 23 controls the amplifier 31 to perform a mute process (step S8). Note that if the volume is suddenly reduced to 0 in the mute process, the sound may be cut off, so that a fade-out process for gradually reducing the volume to 0 may be performed. The reproduction control unit 23 controls the amplifier 31 for the mute process and the fade-out process. Alternatively, the reproduction control unit 23 may process the reproduction data and perform mute processing or fade-out processing, and then output the data to the amplifier 31. Further, the playback control unit 23 may request the playback unit 12 of the track playback device 1 for mute processing and fade-out processing, and the playback unit 12 may perform the processing.

  Next, the track-up request for the number of times determined in step S5 is sent from the playback control unit 23 to the playback unit 12 of the track playback apparatus 1 (step S9). When receiving the track up request from the playback control unit 23, the playback unit 12 immediately executes the track up and switches the track to be played back. For example, when the track A is currently being reproduced, the next track B is the first track, and the next track C is the second track, the number of track-ups is two. The track A being reproduced is shifted to the next track B by the first track up, and the track B is further shifted to the next track C by the second track up. Accordingly, the process of shifting to the track C is performed immediately before the end of the reproduction of the track A, and the track up of the track B which is the first track is realized.

  That is, the playback control unit 23 makes a track-up request for the number of times corresponding to the number of first tracks that are present next to the second track that is currently being played back, so that the track up to the nearest second track is performed. It can be carried out.

  The playback unit 12 immediately executes the track up upon receiving the track up request from the playback control unit 23, but the processing may be delayed for a moment. For this reason, if a track-up request is made at the same time as the reproduction of the second track is completed and the reproduction is switched to the reproduction of the first track, there is a possibility that the sound of the first track flows for a moment, thereby generating a noise. In order to avoid such a situation, the playback control unit 23 issues a track up request immediately before the end of playback of the second track.

  Further, for the above purpose, for example, when the track volume level [dB] drops to a level that cannot be perceived by humans within 1 second before the track playback end time, it is determined that the track playback end is “immediately before”. You may do it. Alternatively, the time point when the track playback data from the track playback device 1 continues to be 0 data for a certain period of time may be determined as “immediately before” the end of track playback.

  In addition, since the track up request for the next track or the like is made immediately before the end of the reproduction of the track, the number of track up requests is at least twice or more. In order to prevent a track up request from being made in time when a track up request is made in succession multiple times, a mute process is performed before the track up request in order to prevent the head portion of the track from being reproduced for a moment.

  After making the track up request, the reproduction control unit 23 cancels the mute process (step S10) and returns to step S2. In step S 2, the information acquisition unit 21 stores the track information of the second track to be newly reproduced in the reproduction history storage unit 24.

  With the above processing, the same track as the track that has been played back in the past and whose playback history is stored in the playback history storage unit 24 is determined to be the first track, and track-up is performed. Therefore, even if there are overlapping tracks in the playback list of the track playback device 1, the tracks can be played back without duplication, and the convenience for the user is improved. In particular, when performing shuffle playback or random playback, the present invention is particularly useful because the same track may be repeatedly played back at short intervals. However, the present invention can also be applied to normal playback other than shuffle playback or random playback.

  Next, the operation of the car navigation device 2B when the next track information cannot be acquired from the track reproducing device 1 will be described with reference to the flowchart of FIG.

  When a track is played back by the playback unit 12 (step S11), the information acquisition unit 21 acquires track information of the track being played back from the track playback device 1, and stores this in the playback history storage unit 24 as a playback history ( Step S12). Next, the playback control unit 23 determines whether or not the playback of the track currently being played is just before ending (step S13). The determination method in this step is the same as that in step S7 in FIG.

  If the reproduction of the track is not immediately before the end, the process waits until the end (step S13: No), and a mute process is performed immediately before the end (step S14). This step is the same as step S8 in FIG.

  Thereafter, when playback of a new track starts in the playback unit 12, the information acquisition unit 21 acquires track information of the track (target track) from the track playback device 1 (step S15). That is, the target track that is the target of track-up determination in the flow of FIG. 5 is the track that is being reproduced. Even when the track reproducing apparatus 1 is restricted from transmitting the next track information according to the standard, the information acquisition unit 21 can acquire the track information because the track information of the track currently being reproduced can be transmitted. .

  The track information of the track currently being reproduced is sent from the information acquisition unit 21 to the determination unit 22, and the determination unit 22 performs track-up determination of the track currently being reproduced based on the track information (step S16). This determination process is the same as step S4 in FIG. If it is determined that the track is the first track, the playback control unit 23 issues a track up request to the playback unit 12 of the track playback device 1 once (step S18), and the playback unit 12 tracks up to the next track. Thereafter, the mute is canceled (step S19), and the process returns to step S12. The process in step S19 is the same as step S10 in FIG.

  When it is determined in step S16 that the currently playing track is the second track, the playing control unit 23 instructs the playing unit 12 to return the playing position to the head of the currently playing track, and the process is executed by the playing unit 12. (Step S17). Thereafter, the mute is canceled (step S19), and the process returns to step S12.

<B-3. Modification>
In the above description, the track playback device 1 is a portable terminal and the playback control device of the present invention is a car navigation device. However, the playback control device of the present invention may be configured as a device other than the car navigation device as long as each component described above is provided as each component of the car navigation device 2B. Further, the track playback apparatus 1 is not limited to a portable terminal, and may be configured by a non-portable music playback apparatus such as a mini component system (minicomponent) as shown in FIG. In this case, the track playback device 1 and the playback control device 2B are components of the mini component system 4.

  In the playback history storage unit 24, track information of a track (second track) played without being tracked up is stored as a history. When the number of history records is unlimited, the playback list of the track playback device 1 is played back as a whole song. At that point, there are no songs that can be played after that. Therefore, in step S4 of FIG. 4, an upper limit may be set for the number of times that the first track is continuously determined. That is, when the track information of a certain number of tracks continuously matches the track information in the playback history storage unit 24, it is determined that the playback list of the track playback device 1 has made a round and the playback history storage unit 24 The history may be deleted and the second track may be determined.

  Alternatively, as another method, an upper limit may be set for the number of histories stored in the reproduction history storage unit 24. For example, half of the number of songs in the playlist of the track playback device 1 may be the upper limit of the number of histories, and when the number of histories reaches the upper limit, the old history may be deleted and a new history may be stored.

  In the Bluetooth standard, each track-up request is a request for track-up to the next track to be reproduced, and it is not possible to instruct track-up to two or more tracks with one track-up request. In the above description, assuming that the Bluetooth standard is assumed, when a plurality of tracks determined to be the first track are continuous, a plurality of track-up requests are made in response thereto. However, when it is possible to instruct to track up to two or more tracks according to the communication standard, it is possible to track up to an arbitrary track with a single track up request.

  In the description of FIG. 3, the determination unit 22 and the reproduction control unit 23 are realized by the processor 41 operating according to a software program stored in the memory 42. However, instead of this, the determination unit 22 and the reproduction control unit 23 may be realized by a signal processing circuit that realizes the operation by a hardware electric circuit. As a concept combining the software determination unit 22 and the reproduction control unit 23 with the hardware determination unit 22 and the reproduction control unit 23, the word “processing circuit” may be used instead of the word “part”.

<C. Embodiment 3>
<C-1. Configuration>
FIG. 7 is a block diagram showing the configuration of the third embodiment. In Embodiment 3, the playback control device of the present invention will be described as a car navigation device, but the playback control device of the present invention is not limited to a car navigation device. In addition to the configuration of the car navigation device 2B according to the second embodiment, the car navigation device 2C according to the third embodiment includes an operation reception unit 25 that is an input / output interface that receives a user's track-up operation.

<C-2. Operation>
FIG. 8 is a flowchart showing the operation of the car navigation device 2C according to Embodiment 3 when the next track information can be acquired. Of the flow of FIG. 8, steps S31, 32, and 33 different from the flow of FIG. 4 described in the second embodiment will be described.

  In the car navigation device 2C, after determining the number of track-ups (step S5), the determination unit 22 determines whether or not a track-up operation has been performed in the track playback device 1 (step S31). When a track up operation is performed in the track reproduction apparatus 1, the track to be reproduced is switched halfway, so that the determination unit 22 knows that the track reproduction operation has been performed in the track reproduction apparatus 1. Alternatively, depending on the communication standard, information indicating that the track up operation has been performed is transmitted from the track playback device 1 to the information acquisition unit 21. Here, although the determination unit 22 has already determined the number of track-ups in step S5, since the track to be reproduced has already been switched to the next track, a track-up request corresponding to the number of track-ups in step S5. There is a concern that the head of the next track may be reproduced for a moment even if it is performed. Therefore, when a track up operation is performed in the track playback device 1 (step S31: Yes), the car navigation device 2C returns to step S2 without making a track up request. Then, the information acquisition unit 21 stores the track information of the newly reproduced track in the reproduction history storage unit 24.

  When there is no track up operation in the track playback device 1 (step S31: No), the determination unit 22 determines whether there is a track up operation in the car navigation device 2C (step S32). The track-up operation for the car navigation device 2C is input to the operation reception unit 25, and the operation information is sent from the operation reception unit 25 to the determination unit 22. Therefore, the determination unit 22 performs the determination in step S32 based on this information.

  If there is no track-up operation for the car navigation device 2B, the process proceeds to step S6. If there is a track-up operation for the car navigation device 2B, the number of track-ups determined in step S5 is corrected (step S33). Here, the number (A) of track-up operations performed by the playback control device is compared with the number of track-ups (B) determined in step S5. If A ≦ B, B is the number of track-up requests ( No correction). However, if A> B, the track-up determination in step S4 is performed for the track 2 after A from the currently reproduced track 1. For track 2, if track up is not present, A is the number of track up requests, and if track up is present, track up determination is similarly performed for the track after track 2. Then, the number obtained by adding the number of tracks after track 2 that has been continuously determined to have track-up to A is defined as the number of track-up requests. As described above, the determination unit 22 determines the number of track-up operations for the car navigation device 2B, the number of first tracks that are present next to the second track that is currently being reproduced, and the second track that is currently being reproduced. By determining the number of times of track-up according to the number of first tracks continuously existing after the number of times of track-up operation for the car navigation device 2B from Do not become the first track.

  Thereafter, the mute process is performed without waiting for the reproduction of the currently reproduced track to be just before the end (step S8), and a track up request is made (step S9). As described above, when the user performs a track-up operation on the car navigation device 2B, the intention of the user can be reflected by performing the track-up at the timing when the operation is performed.

  FIG. 9 is a flowchart showing the operation when the next track information cannot be acquired by the car navigation device 2C according to the third embodiment. Of the flow of FIG. 9, steps S34-37 different from the flow of FIG. 5 described in the second embodiment will be mainly described.

  When the playback of the track is started in the playback unit 12 (step S11), the information acquisition unit 21 acquires the track information of the track being played back from the track playback device 1, and stores this in the playback history storage unit 24 as a playback history. (Step S12). The determination unit 22 determines whether or not a track up operation has been performed in the track playback device 1 (step S34). This determination process is the same as step S31 in FIG.

  Here, when a track-up operation is performed in the track playback device, a track-up process is performed in the playback unit 12 and a new track is immediately played back, so the car navigation device 2C does not perform a track-up determination process. Then, the information acquisition unit 21 stores the reproduction history of the new track in the reproduction history storage unit 24 (step S12), and returns to step S34.

  If there is no track up operation in the track playback device 1, the determination unit 22 determines whether there is a track up operation in the car navigation device 2C (step S35). This determination processing is the same as step S32 in FIG. If there is a track-up operation in the car navigation device 2C, the playback control unit 23 performs a mute process without waiting for the track being currently played back immediately before the end of playback (step S36). A track-up request is made to the playback unit 12 for the number of times of input (step S37). When the playback unit 12 performs track up and a new track is played back, the track information of the track is acquired (step S15).

  If there is no track up operation in the car navigation device 2C, the process proceeds to step S13, and if not immediately before the end of the reproduction of the track, the process proceeds to step S12.

<C-3. Modification>
In the second and third embodiments, the determination unit 22 of the car navigation devices 2B and 2C determines that the track information of the track scheduled to be reproduced or being reproduced matches the track information stored in the reproduction history storage unit 24. Therefore, the same track is prevented from being repeatedly reproduced. However, the determination unit 22 may perform the track-up determination by another method.

  For example, referring to the performance time of the track described in the track information, a track that does not fall within a predetermined time range may be determined as the first track. Thereby, the performance time is too long, or the performance time is too short. Albums may contain short tracks for connecting songs, and these connected tracks are meaningless unless played through the album, so shuffle or random playback When performing, it is desirable to track up. On the other hand, an extremely long playing time such as an audio book may not be suitable for shuffle playback or random playback. By tracking up such a track, user convenience is improved. The track-up determination based on the reproduction history and the track-up determination based on the performance time may be combined, or any one of the determination methods may be performed. When only the track-up determination based on the performance time is performed, the reproduction history storage unit 24 is not necessary in the car navigation devices 2B and 2C.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
