It is disclosed.

Hei 9-198853

  Such a reproducing apparatus may be used as a music reproducing apparatus used by a DJ (Disc Jockey) equipped with an operator such as a turntable in addition to the above-described general CD player.

  In many cases, a DJ who operates a music playback device plays a plurality of music seamlessly by mixing the music played on the two music playback devices. In this way, when playing a plurality of music without interruption, the DJ uses a music playback device on the other side while the music being played on one music playback device is flowing from the speaker of the club. In many cases, the music to be reproduced next (that is, the music to be played from the club speaker next) is determined from a plurality of music by listening to the music being reproduced with headphones while sequentially reproducing the music. . For this reason, there arises a technical problem that it is necessary to determine the music to be reproduced next within the reproduction time of the music on one music reproduction device (for example, within 1 to 2 minutes). In order to avoid the influence on the reproduction of the music due to such technical problems (for example, the influence that the reproduction of the music is interrupted), the music to be reproduced next is determined from a plurality of music. Therefore, it is preferable to shorten the time required for this as much as possible.

  Such a technical problem may occur not only in a music playback device that plays back music but also in a playback device that plays back any content such as video. Furthermore, such a technical problem is not only when determining the next content to be reproduced from a plurality of contents (for example, music), but also for desired contents from the plurality of contents (for example, music). The same can occur when determining content.

  Examples of problems to be solved by the present invention include the above. The present invention provides a playback apparatus and method capable of shortening the time required to determine a desired content from a plurality of contents, and a computer program that causes a computer to be executed as such a playback apparatus. Let it be an issue.

  In order to solve the above-described problem, a playback apparatus according to the present invention includes an operation unit that receives a selection operation for selecting first content for which a playback start position is set in advance, and the first content by the selection operation. And playback means for starting playback of the first content from the playback start position set for the first content selected by the selection operation at the same time as the music is selected.

  In order to solve the above problems, a playback method according to the present invention includes an operation step of receiving a selection operation for selecting a first content having a playback start position set in advance, and the first content of the first content by the selection operation. And a playback step of starting playback of the first content from the playback start position set for the first content selected by the selection operation at the same time as the music is selected.

  In order to solve the above problems, the computer program of the present invention causes a computer to execute the reproduction method of the present invention.

  Such an operation and gain of the present invention will be clarified from the embodiments described below.

It is a block diagram which shows an example of a structure of the music reproduction apparatus of a present Example. It is a flowchart which shows the flow of music determination operation | movement among operation | movement of the music reproduction apparatus of a present Example. It is a top view which shows the selection operation of the user for selecting arbitrary music from the some music which a music list shows on a music list.

  Hereinafter, as embodiments for carrying out the invention, embodiments of the playback apparatus and method and the computer program of the present invention will be described in order.

(Embodiment of playback device)
<1>
The playback device according to the present embodiment is configured to receive a selection operation for selecting first content whose playback start position is set in advance, and when the music of the first content is selected by the selection operation. At the same time, a playback unit that starts playback of the first content from the playback start position set for the first content selected by the selection operation.

  According to the playback apparatus of the present embodiment, the operation means accepts a selection operation for selecting the first content. Note that such a selection operation is typically performed by a user of the playback device.

  A playback start position is set in advance for the first content. The reproduction start position indicates a position (in other words, time or starting point) where reproduction of the first content is started. Therefore, when the reproduction of the first content is started according to the preset reproduction start position, the first content is reproduced from the preset reproduction start position. However, the first content may be reproduced from an arbitrary position.

  The reproduction means starts reproduction of the first content selected by the selection operation at the same time that the operation means accepts the selection operation. At this time, the reproduction means starts reproduction of the first content from a reproduction start position set in advance for the first content. In other words, the playback unit can start playback of the first content without receiving or needing to receive a user operation for starting playback of the first content after receiving the selection operation. Furthermore, the playback means does not require a user operation for determining the playback start position of the first content, or the playback means itself performs a process for determining the playback start position of the first content. The reproduction of the first content can be started without performing it. Therefore, the reproducing means can start the reproduction of the first content quickly. As a result, the playback device according to the present exemplary embodiment compares the first content with the playback device that needs to accept a user operation for starting playback of the first content selected by the selection operation. It is possible to shorten the time required from the selection until the reproduction of the selected first content is started.

  Here, when a selection operation for sequentially selecting a plurality of contents is performed, each time a selection operation for selecting a new content is performed, the newly selected content is reproduced at the same time as the selection operation is performed. Be started. For this reason, the user can view the reproduced content while reproducing the plurality of contents by performing a selection operation for sequentially selecting the plurality of contents. As a result, the user can easily determine desired content (for example, content to be reproduced next) from among a plurality of contents based on the viewing results of the sequentially reproduced content. In particular, in the playback device of the present embodiment, the first content is selected after the first content is selected as compared to the playback device that needs to further accept a user operation for starting playback of the first content. As described above, the time required to start reproduction of one content is shortened. Therefore, the playback apparatus of this embodiment can naturally shorten the time required to determine a desired content from a plurality of contents.

<2>
In another aspect of the playback apparatus of the present embodiment, the operation means further accepts the selection operation for selecting the second content for which the playback start position is not set in advance, and the second operation is performed by the selection operation. When the content is selected, there is further provided a setting unit that newly sets a position corresponding to a content portion whose characteristics satisfy a predetermined condition among the second content as the reproduction start position, and the reproduction unit includes: When the second content is selected by the selection operation, reproduction of the second content is started from the reproduction start position generated by the generation unit.

  According to this aspect, even when the second content whose reproduction start position is not set in advance is selected by the selection operation, the reproduction start position of the second content is automatically ( For example, the playback start position is set without requiring a user operation to individually set the playback start position. For this reason, the playback apparatus of this aspect needs to further accept a user operation for setting the playback start position of the second content selected by the selection operation and starting playback of the second content. Compared to the playback device, it is possible to shorten the time required from when the second content is selected to when playback of the selected second content is started.

<3>
As described above, in the aspect of the playback apparatus in which the playback position corresponding to the content portion whose characteristics satisfy the predetermined condition in the second content is newly set as the playback start position, the signal level of the content portion is equal to or higher than the predetermined level. Content part.

  According to this aspect, the reproduction means can start the reproduction of the second content from the content portion where the signal level is equal to or higher than the predetermined level. That is, the reproducing means does not start the reproduction of the second content from the content portion where the signal level is less than the predetermined level. As a result, for example, the reproduction of the second content is not started from a content portion that is silent or no video. For this reason, the playback apparatus of this aspect is particularly useful when used as a music playback device in which playback of uninterrupted content (in other words, continuous playback of content) is desirable.

<4>
In another aspect of the playback apparatus of the present embodiment, the operation unit further accepts a determination operation for determining the first content being played back by the playback unit as a playback target content, and the playback unit includes: When the first content is determined as the playback target content by the determination operation, the playback of the first content is performed after preparing to start playback of the first content from a desired playback position. Transition to a standby state that does not actually start.

  According to this aspect, the user can reproduce a plurality of contents without interruption. Specifically, the user can first perform a selection operation for selecting the first content and a determination operation for determining the content to be played while other content is being played on another playback device. As a result, while other content is being played back on another playback device, playback of the first content that is the playback target content is not actually started. Thereafter, when the other content being played back on the other playback device is played back to an appropriate position, the user plays back the first content that is the playback target content from the standby state, from the standby state. Transition to the playback state. As a result, the playback state of the content (typically, the playback state of the content being viewed by the audience) from the state in which other content being played back on other playback devices is being played back as playback target content, The state shifts to a state where the first content determined by the determination operation is being reproduced as a new reproduction target content. For this reason, a plurality of contents are reproduced without interruption.

  In addition to or instead of the determination operation for determining the first content being played back by the playback means as the playback target content, the operation means uses the second content being played back by the playback means as the playback target content. A determination operation for determining as may be accepted. In this case, the playback unit may wait without actually starting playback of the second content after preparing to start playback of the second content from a desired playback position.

(Embodiment of reproduction method)
<5>
In the playback method of the present embodiment, an operation step of receiving a selection operation for selecting the first content whose playback start position is set in advance, and when the music piece of the first content is selected by the selection operation At the same time, a playback step of starting playback of the first content from the playback start position set for the first content selected by the selection operation.

  According to the playback method of the present embodiment, it is possible to receive the same benefits as the various benefits of the playback device of the present embodiment described above. Incidentally, in response to the various aspects of the reproduction apparatus of the present embodiment described above, the reproduction method of the present embodiment can also adopt various aspects.

(Embodiment of computer program)
<6>
The computer program of the present embodiment causes a computer to execute the above-described reproduction method of the present embodiment (including various aspects thereof).

  According to the computer program of the present embodiment, it is possible to receive the same benefits as the various benefits of the playback apparatus of the present embodiment described above.

  The music storage unit 11 stores music (in other words, music data indicating music) that is played back by the music playback device 1. In particular, in this embodiment, the music storage unit 11 preferably stores a plurality of music. The music storage unit 111 is typically an arbitrary storage device (for example, a hard disk or a semiconductor memory).

  The cue point information storage unit 12 stores cue points set in advance for each of a plurality of pieces of music stored in the music storage unit 11. A single cue point may be set for each musical piece. A plurality of cue points may be set for each piece of music data.

  The cue point is information for specifying a specific reproduction position (in other words, a specific reproduction time) in the music. In this embodiment, the cue point is information that specifies a reproduction position at which the reproduction of the music is started (in other words, a reproduction time at which the reproduction of the music is started).

  The cue point may be set by the cue point analysis unit 16. For example, the cue point analysis unit 16 sets the cue point of the newly stored music by analyzing the newly stored music when the music storage unit 11 newly stores the music. May be. Alternatively, the cue point may be set by the user (typically DJ) of the music playback device 1. For example, when the user performs an operation of specifying a cue point using the operation unit 14, the cue point storage unit 12 may newly store the cue point specified by the user using the operation unit 14. .

  The display unit 13 displays various information related to the operation of the music playback device 1.

Particularly in the present embodiment, the operation unit 14 receives a user operation on the music list displayed by the display unit 13 (for example, a user operation to select an arbitrary music from a plurality of music indicated by the music list). For this reason, for example, the operation unit 14 may be an operator (for example, a touch panel) that is arranged on or integrated with the display screen of the display unit 13. For example, the operation unit 14 is an operator (for example, a mouse, an operation key, or a touch) for arbitrarily moving a selection position (for example, a highlight or a cursor described later with reference to FIG. 3) in the display screen of the display unit 13. Pad, etc.).

  The operation content analysis unit 15 analyzes the user operation received by the operation unit 14. Particularly in the present embodiment, the operation content analysis unit 15 determines whether or not the user operation received by the operation unit 14 is an operation of selecting an arbitrary piece of music from a plurality of pieces of music indicated by the music list displayed by the display unit 13. Is analyzed. The operation content analysis unit 15 is typically a processing block that is logically realized on the CPU when the computer program is executed by the CPU included in the music playback device 1.

The cue point analysis unit 16 is typically a processing block that is logically realized on the CPU when the computer program is executed by the CPU included in the music playback device 1.

  The music playback unit 17 reads the music stored in the music storage unit 11 and plays back the read music. In the present embodiment, the music playback unit 17 plays back music through at least one of headphones and speakers. As a result, music flows from at least one of the headphones and speakers connected to the music playback device 1. The headphone is typically an output device for the user of the music playback device 1 to listen to the music, while the speaker is typically used by a club audience in which the music playback device 1 is installed. This is an output device for listening to music. However, the music reproducing unit 17 may reproduce the music via any output device other than the headphone and the speaker in addition to or instead of at least one of the headphone and the speaker. The music playback unit 17 typically has a dedicated hardware for playing back a processing block or music that is logically realized on the CPU when the computer program is executed by the CPU of the music playback device 1. Circuit.

  The data bus 18 includes a music storage unit 11, a cue point storage unit 12, a display unit 13, an operation unit 14, an operation content analysis unit 15, a cue point analysis unit 16, and a music reproduction unit 17. It is a signal path for transmitting and receiving information.

  In the above description, the music playback device 1 includes the music storage unit 11, the cue point storage unit 12, the display unit 13, the operation unit 14, the operation content analysis unit 15, the cue point analysis unit 16, and the music playback unit 17. The example provided with is shown. However, the music playback device 1 includes at least a part of a music storage unit 11, a cue point storage unit 12, a display unit 13, an operation unit 14, an operation content analysis unit 15, a cue point analysis unit 16, and a music playback unit 17. On the other hand, the music storage unit 11, the cue point storage unit 12, the display unit 13, the operation unit 14, the operation content analysis unit 15, the cue point analysis unit 16, and the music reproduction unit 17 are not provided. Also good. For example, the music playback device 1 may not include the cue point analysis unit 16. In this case, the music reproducing device 1 may not perform the operation to be performed by the cue point analysis unit 16 and the operation related to the operation (for example, the operation from step S15 to step S17 in FIG. 2 described later). Similarly, in the case where the music playback device 1 does not include other components, the music playback device 1 may not perform the operation to be performed by the other components and the operation related to the operation.

  Alternatively, the music playback device 1 includes at least a part of the music storage unit 11, the cue point storage unit 12, the display unit 13, the operation unit 14, the operation content analysis unit 15, the cue point analysis unit 16, and the music playback unit 17.

For example, when the music playback device 1 is a so-called DJ controller (for example, a user interface device having a number of controls having an appearance like a DJ player or a mixer), the music playback device 1 includes at least the display unit 13 and While the operation unit 14 is provided, another device (for example, at least one of a personal computer and a DJ player) connected to the music playback device 1 is connected to the music storage unit 11, the cue point storage unit 12, and the operation content analysis. At least a part of the unit 15, the cue point analysis unit 16, and the music playback unit 17 may be provided.

(2) Operation of Music Playback Device 1 Next, the flow of operation of the music playback device 1 will be described with reference to FIG. Below, the flow of music determination operation | movement among the operation | movement of the music reproduction apparatus 1 is demonstrated. FIG. 2 shows an example of the flow of the music determination operation among the operations of the music playback device 1.

  Note that the “music determination operation” in the present embodiment means that a plurality of music stored in the music storage unit 11 is sequentially played back via headphones, and the user is asked to listen to the music from the plurality of music. This means an operation for determining one piece of music to be played through (ie, to be heard by the audience). However, the “music determination operation” may be an operation of determining a desired music from a plurality of music stored in the music storage unit 11 (in other words, extracting a desired music).

  As shown in FIG. 2, first, the display unit 13 displays a music list indicating a list of a plurality of music items stored in the music storage unit 11 (step S <b> 12). The music list may indicate a list of all of a plurality of music. The song list may indicate a list of at least a part of the plurality of songs.

  Thereafter, the operation content analysis unit 15 determines whether or not the user operation received by the operation unit 14 is a selection operation for selecting an arbitrary song from a plurality of songs indicated by the song list displayed by the display unit 13. To analyze. That is, the operation content analysis unit 15 analyzes the display content of the display unit 13 and the user operation content received by the operation unit 14, thereby determining whether any music is selected from a plurality of music indicated by the music list. Is determined (step S13).

  Here, the user's selection operation for selecting an arbitrary piece of music from a plurality of pieces of music shown in the music list will be described with reference to FIG. FIG. 3 is a plan view showing a user's selection operation on the song list for selecting an arbitrary song from a plurality of songs shown in the song list.

  As shown in FIG. 3A, the display unit 13 displays a music list indicating a music named “ABCDE”, a music named “FGHIJK”, a music named “LMNOP”, and the like. To do. The music list shown in FIG. 3A is only an example. Therefore, the display unit 13 may display a music list in a format different from the music list shown in FIG. In short, it is sufficient for the display unit 13 to display some information that can specify the music as a music list.

  As shown in FIG. 3B, when the operation unit 14 includes an operation key, the user highlights the selected music in a desired direction (for example, upward, downward, rightward). Alternatively, an operation of moving in the left direction may be performed as a selection operation. In this case, the music on which the highlight is located is the music selected by the user. For example, if the user presses the down key, which is an example of the operation key, with respect to the music list in the state shown in FIG. 3B, the highlight is the music named “FGHIJK” from the music named “ABCDE”. Move to. Such a user operation corresponds to a selection operation for selecting a song having the name “FGHIJK”.

  As shown in FIG. 3C, when the operation unit 14 includes a mouse, the user performs an operation of moving a cursor that substantially indicates the current position of the mouse in a desired direction as a selection operation. Also good. In this case, the music on which the cursor is located is the music selected by the user. For example, if the user moves the mouse downward in the music list in the state shown in FIG. 3C, the cursor moves from the music named “ABCDE” to the music named “FGHIJK”. To do. Such a user operation corresponds to a selection operation for selecting a song having the name “FGHIJK”.

  Even when the operation unit 14 includes a touch panel, a touch pad, or other operation elements, the user may select a music piece by moving a highlight or a cursor. Further, not only a user interface for selecting a music piece using a highlight or a cursor, but also a user interface that can distinguish a music piece selected in some form from other music pieces may be used.

  It should be noted that the selection operation is preferably as simple as possible, simplified or not complicated. For example, the selection operation may be an operation of simply moving the position (for example, the highlight shown in FIG. 3B or the cursor shown in FIG. 3C) currently selected by the user. In this case, the selection operation may be an operation that does not require the selection position to be determined after the selection position is moved while the user's current selection position is simply moved. For example, in the example shown in FIG. 3B, the selection operation is an operation of pressing the operation key at least once to move the highlight. In other words, in the example shown in FIG. 3B, the selection operation is performed by pressing the operation key at least once to move the highlight and then pressing the confirmation key (return key) to confirm the highlight position. It is an operation that does not need to be performed. Similarly, in the example shown in FIG. 3C, the selection operation is an operation of moving the mouse. In other words, in the example shown in FIG. 3C, the selection operation is an operation that does not require clicking the mouse button to determine the position of the cursor after moving the mouse to move the cursor.

  In FIG. 2 again, as a result of the determination in step S13, when it is determined that the user's operation is not a selection operation (that is, any music is not selected from a plurality of music shown in the music list) (step S13: No), the operation content analysis unit 15 continues to analyze whether or not the user operation received by the operation unit 14 is a selection operation (step S13).

  On the other hand, as a result of the determination in step S13, when it is determined that the user's operation is a selection operation (that is, an arbitrary song is selected from a plurality of songs indicated by the song list) (step S13: Yes). ), The music playback unit 17 starts playback of the selected music via the headphones at the same time that the user's operation is determined to be a selection operation (step S14). In particular, the music playback unit 17 automatically starts playback of the selected music from the cue point of the selected music (that is, the cue point preset for the selected music). (Step S14). For this reason, the music reproducing unit 17 determines that the user's operation is a selection operation, and simultaneously acquires the cue point of the selected music from the cue point storage unit 12 and is selected from the acquired cue point. Start playing the current song.

  In the state of “starting playback of the selected music at the same time as determining that an arbitrary music is selected”, an operation of “determining that an arbitrary music is selected” is performed. This means a state in which “the cue point of the selected music is acquired and the reproduction of the music selected from the acquired cue point is started” without interruption or without further user operation. . In other words, the state of “starting the playback of music at the same time as determining that an arbitrary music is selected” is the state of “determining that an arbitrary music is selected” and “ The operation that is the minimum necessary to start the playback of the selected music (typically, the music playback device 1 that does not require further user operation) This may mean a state in which a supplementary or automatic operation) is allowed to be performed. However, the state of “starting playback of music at the same time that it is determined that an arbitrary music is selected” is literally “timing that an arbitrary music is selected” and “selected” It may mean a state in which the timing of “starting the reproduction of music” matches with no error.

  On the other hand, the music reproducing unit 17 cannot always obtain the cue point of the selected music. For example, when the cue point of the selected music is not stored in the cue point storage unit 12, the music reproducing unit 17 cannot acquire the cue point of the selected music (Step S15: No). ). Therefore, when the music playback unit 17 cannot acquire the cue point of the selected music (step S15: No), the cue point analysis unit 16 is selected by analyzing the selected music. A new cue point is set for the music (step S16). In this case, it is preferable that the cue point storage unit 12 stores the cue point newly set by the cue point analysis unit 16. Thereafter, the music playback unit 17 starts playback of the selected music from the newly set cue point (step S17).

  The setting of a new cue point by the cue point analysis unit 16 may be performed using a known method. For example, the cue point analysis unit 16 may set a playback position corresponding to a music part whose signal level is equal to or higher than a predetermined level as a new cue point. Alternatively, for example, the cue point analysis unit 16 may generate a reproduction position corresponding to a music portion having a predetermined characteristic as a new cue point. In any case, it is preferable that the cue point analysis unit 16 sets a new cue point based on some cue point generation criterion.

  Thereafter, the operation content analysis unit 15 determines whether or not the user operation received by the operation unit 14 is a determination operation for determining the selected music piece to be played from the speaker. That is, the operation content analysis unit 15 determines whether or not the selected music has been determined as a reproduction target music to be played from the speaker (step S18).

  For example, as illustrated in FIG. 3B, when the operation unit 14 includes an operation key, the user determines the selected music (that is, the music on which the highlight is located) as the music to be played. As the determination operation to perform, an operation of pressing the confirmation key may be performed. Alternatively, the user presses the operation key that does not move the highlight for a predetermined time or more (that is, presses the operation key for the predetermined time or more) as a determination operation for determining the selected music (that is, the music where the highlight is located) as the reproduction target music. May not be performed).

  For example, as illustrated in FIG. 3C, when the operation unit 14 includes a mouse, the user determines to select the selected music (that is, the music on which the cursor is located) as the music to be played. As an operation, an operation of clicking a mouse button may be performed. Alternatively, the user does not move the cursor for a predetermined time or longer (that is, does not move the mouse for a predetermined time or longer) as a determination operation for determining the selected music (that is, the music on which the cursor is located) as the music to be played. May be performed.

  In any case, it is preferable that the user performs an operation different from the selection operation for selecting an arbitrary music from a plurality of music shown in the music list as the determination operation for determining the selected music as the music to be played.

  As a result of the determination in step S18, when it is determined that the user's operation is not a determination operation (that is, the selected music is not determined as a reproduction target music) (step S18: No), the music playback device 1 Repeats the operations after step S13. That is, the music playback device 1 continues the operation of starting playback of the selected music from the cue point. When another music piece is newly selected, the music reproducing device 1 newly performs an operation of starting reproduction from the cue point of another newly selected music piece. Therefore, when the user sequentially selects a plurality of songs, the music playback device 1 sequentially performs an operation of starting playback of the music from the cue point for a plurality of songs.

  On the other hand, as a result of the determination in step S18, when it is determined that the user's operation is a determination operation (that is, the selected music is determined as a reproduction target music) (step S18: Yes), The music playback unit 17 waits for playback of the playback target music (step S19). Specifically, the music playback unit 17 prepares to start a playback operation for playing back the playback target music from the desired playback position (for example, to the buffer memory of the music portion near the desired playback position of the playback target music Read). Then, the music playback unit 17 waits for a user operation to instruct the start of playback of the playback target music without actually playing back the playback target music (that is, without actually playing back from the speaker). Thereafter, when the user's operation for instructing the start of reproduction of the reproduction target music is performed, the music reproduction unit 17 starts reproduction of the reproduction target music.

  As described above, the music playback device 1 according to the present embodiment determines that the user's operation is a selection operation (that is, any music is selected from a plurality of music shown in the music list). The playback of the selected music is started from the cue point preset for the selected music via the headphones. That is, the music playback device 1 starts playback of the selected music without receiving or needing to receive further user operation for starting playback of the music selected after receiving the selection operation. be able to. Furthermore, the music playback device 1 receives the selection operation in advance without receiving or needing to receive a user operation for determining the playback start position of the music selected after receiving the selection operation. Playback of the selected music can be started from the set cue point. Therefore, the music playback device 1 can quickly start playback of the selected music. That is, the music playback device 1 selects the music after selecting the music compared to the music playback device of the comparative example that needs to further accept the user's operation for starting playback of the selected music. It is possible to shorten the time required to start the reproduction.

  Here, when a selection operation for sequentially selecting a plurality of songs is performed, the music playback device 1 is newly selected at the same time as the selection operation is performed each time a selection operation for selecting a new song is performed. Start playing the song. For this reason, the user performs a simple selection operation by simply pressing an operation key to move a highlight or moving a mouse to move a cursor, thereby reproducing a plurality of music pieces. It is possible to listen to the music being played (for example, to confirm the tone of the music). As a result, the user can easily determine the music to be played (that is, the music to be played next through the speaker) from the plurality of music based on the viewing results of the music that is played sequentially. In particular, in this embodiment, since the time required to start playback of the selected music after the selection of the music is shortened, the time required to determine the playback target music from a plurality of music is also increased. Naturally shortened. That is, the user can quickly determine a music to be played (that is, a music to be played next through a speaker) from among a plurality of music.

  In addition, in the present embodiment, the music reproducing device 1 can newly set a cue point even when a user selects a music for which no cue point is set in advance. For this reason, the music reproducing device 1 can shorten the time required from the selection of a music for which cue points are not set in advance to the start of the reproduction of the selected music.

  In particular, when the music playback device 1 newly sets a cue point of a music for which no cue point is set in advance, a position corresponding to a music portion whose signal level is equal to or higher than a predetermined level is set as a new cue point. can do. As a result, for example, the reproduction of the music is not started from the music part that becomes silent. For this reason, the music playback device 1 is particularly useful when the music playback device 1 is used as a DJ device in which playback of music without interruption (in other words, continuous playback of music) is desirable.

  The present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit or idea of the invention that can be read from the claims and the entire specification, and a reproducing apparatus with such changes And methods and computer programs are also included in the technical scope of the present invention.
