Description

  The present invention relates to a playback apparatus and playback method capable of playing back audio data managed in units of programs.

  For example, digital audio systems capable of reproducing audio data such as music pieces are widely used, including audio devices compatible with CDs (Compact Discs) and so-called minidiscs.

In such an audio system, audio data recorded on a medium is usually managed in units of programs for each piece of music, for example. Therefore, for example, in the case of normal playback, audio data is sequentially played back in accordance with the program number order.
Hereinafter, in the present specification, the program is also referred to as a track.

  By the way, in the case where the tracks are sequentially played as described above, for example, since the music as the track to be played next is not a favorite, there is a demand for skipping (sending) this so that it is not played back. Is of course conceivable.

  However, for example, during normal playback, it is possible to know the track number to be played next by looking at the track number being played currently displayed on the display unit of the audio device. To skip only the next track to be played, when playback of the currently playing track ends and playback of this next track starts, cueing to the next track is performed. Need to do. That is, when a certain track is currently being reproduced, it is not possible to skip only the next reproduced track.

For this reason, various audio devices have a so-called program reproduction function. This program playback function allows, for example, an arbitrary number of tracks to be selected from all tracks recorded on a certain recording medium in accordance with the desired track order to be played back. It is.
However, in general, the program setting as described above is performed at a stage before reproduction, and the program content cannot be changed while reproduction according to the set program content is being performed.
Here, for example, even during program playback, even if you want to skip the next track to be played due to the user's mood at that time, for example, you can skip this as described above. Thus, after the reproduction of the currently reproduced track is completed, it is necessary to perform an operation for cueing to the next track.

Such audio equipment is also provided with a so-called shuffle playback function. Shuffle playback is to perform track playback by determining a random track order by, for example, appropriately generating random numbers on the device side.
In the case of such shuffle playback, the track to be played next is not presented to the outside by, for example, display or the like, and the user cannot grasp the next music (track).
Therefore, in the case of shuffle playback, even if the user wants to skip the next music to be played as described above, in this case, the user can know the music to be played next in advance. There will be no. Therefore, in this case, when a certain track is started to be played, it will be known for the first time that this song is not preferred. At this stage, the next track is cued and the next track is You can only expect that it is your favorite song.

  The present invention is currently played back as a playback device capable of playing back at least a predetermined recording medium on which audio data associated with related data of the program, which is managed by a unit as a program, is recorded. A next program determination means for randomly determining a next program to be reproduced next to a program that is determined to be a reproduced program that has been reproduced so far without being included in candidates for determination of the next program; A first display area for displaying a title of a program that is currently being reproduced, and a next program title for displaying a title of the next program to be reproduced next for the next program determined by the next program determining means. Display means including two display areas and a program currently being played based on the related data. Comprising a program presenting means for controlling to display on the display means the title of the program to be reproduced ram title and the next, the.

  The playback apparatus further includes skip operation means. When an operation is performed on the skip operation means during playback of a certain program, the next program determination means determines the current next program. And the program to be reproduced next to the program for which this determination has been canceled is determined, the determined program is set as a new next program, and the current displayed in the second display area The display is changed to the title of the program to be reproduced next to the program canceled from the title of the next program in the program, and the skip setting process is executed, and the determination as the next program before the reproduction is performed by the skip setting process. If a program has been canceled, it must be considered a replayed program. By not treated, to be included in the candidate of the determination of the next program in after the skip setting process.

In addition, the present invention provides a reproduction apparatus capable of performing reproduction corresponding to a predetermined recording medium on which audio data associated with at least program-related data managed by a unit as a program is recorded. As a method, the next program to be reproduced next to the program that is currently being reproduced is determined at random without including the reproduced program that has been reproduced so far as candidates for determination of the next program. A next program determination procedure, a program presentation procedure for controlling the display means to display the title of the program currently being reproduced and the title of the program to be reproduced next based on the related data, and the program presentation procedure The title of the program that is currently being played is displayed in the first display area of the display means. And a display procedure of the title of the next program to be reproduced next is determined by the following program determining step displays on the second display area of the display means,
Is provided.

  Further, the reproduction method includes a skip operation procedure. When an operation is performed on the skip operation procedure while a certain program is being reproduced, the next program determination procedure determines whether the next program is currently determined. And the program to be reproduced next to the program for which this determination has been canceled is determined, the determined program is set as a new next program, and the current displayed in the second display area The display is changed to the title of the program to be reproduced next to the program canceled from the title of the next program in the program, and the skip setting process is executed, and the determination as the next program before the reproduction is performed by the skip setting process. If a program has been canceled, it will be By not adversely to be included in the candidate of the determination of the next program in after the skip setting process.

As described above, according to the present invention, for example, when a track (program) as a certain musical piece is being reproduced, the next track that is the track to be reproduced next is presented to the user. For example, if the user grasps the presented next track and does not want to listen to the next track, even if the previous track is being played, the user can skip the track to be played next, and Can perform an operation to set a different track as the next track.
For example, conventionally, in order to prevent the next track from being listened to by listening, the user waits for the playback of the previous track to end and the playback of the next track to start, for example, cueing in the feed direction. The track was skipped by performing the operation. In other words, when the previous track was being played, the next track could not be skipped and had to wait until the previous track finished playing. On the other hand, in the present invention, when a track is being played, the next track can be skipped, so there is no need to wait for the end of the track play as described above, and the user convenience is improved accordingly. It is what is done.

  In particular, at the time of shuffle playback, since the track to be played next has not been presented in the past, the user did not know the content of the song until the playback of the next track was started. is there. Therefore, for example, if the present invention is applied at the time of shuffle playback, at least the next music (track) is presented to the user, and the end of the currently playing track is not waited as described above. This is particularly useful because the next track can be skipped.

  In addition, according to the present invention, a track that is a target of skipping, that is, a track whose determination as a next track is canceled by skip processing, is not treated as being played back, and is determined as a candidate for determination of the next track from the next time The track can be included, or the track to be skipped can be treated as being played and not included in the next track determination candidate from the next time. In the case of shuffle playback that is random without the order being determined in advance, a variation in track playback accompanying the skip operation can be obtained, thereby increasing the added value.

Hereinafter, embodiments of the present invention will be described. In this embodiment, a recording / reproducing apparatus capable of recording / reproducing at least audio data corresponding to a predetermined disc-shaped recording medium (or a solid-state memory element such as a flash memory) is used.
The following description will be given in the following order.

1. 1. Recording / reproducing apparatus 2. Data contents recorded on the disc Skip operation Processing action

1. Recording / playback device

The block diagram of FIG. 1 shows a configuration example as a recording / reproducing apparatus of the present embodiment.
In the recording / reproducing apparatus 1 shown in this figure, a disk driver 5 is provided. The disk driver 5 has a configuration capable of reading and writing data on a predetermined disk-shaped recording medium (hereinafter simply referred to as a disk) 20. Further, in the present embodiment, audio data can be recorded on the disk 20, but this audio data is managed and recorded in units of tracks for each piece of music, for example.
In the present embodiment, the disk 20 supported by the disk driver 5 is not particularly limited as long as it is at least a format in which audio data can be recorded or reproduced. However, in this embodiment, as will be described later, a character information file and an image file (hereinafter referred to as “audio-related data”) that are associated with each piece of audio data as a track can be recorded and reproduced. .

  An example of the type of the disk 20 may be a magneto-optical disk such as a mini disk, or may be a disk capable of recording or reproducing various data according to the CD method or the DVD method. Furthermore, a hard disk etc. can be considered. Further, in the following description, the description will be made on the premise of the disk medium, but instead of the disk driver 5, a configuration as a memory driver capable of recording / reproducing corresponding to a solid-state memory such as a flash memory may be adopted. There is nothing.

At the time of recording, the audio data processor 9 performs, for example, data compression processing according to a required method, error correction code addition processing, encoding processing suitable for the disc 20 and the like on the input audio data. The required signal processing is performed and supplied as recording data to the disk driver 5 via the data bus 30.
At the time of reproduction, audio data read from the disk 20 by the disk driver 5 is taken in via the data bus 30 and subjected to demodulation processing, data expansion processing, error correction processing, etc. according to a required system. Output as playback audio data.

In the configuration shown in this figure, there are two systems for recording data input to the audio data processor 9.
One is a signal system for inputting audio data supplied from the A / D converter 12. In this case, the microphone audio signal supplied from the microphone terminal T <b> 1 is input to the A / D converter 12 via the microphone amplifier 13. The A / D converter 12 is also connected to a line input terminal T2 to which an analog audio signal is input.
The other is a signal system for inputting audio data transmitted from an external device from the connector 11 via the data interface 10 via the data bus 30.

In this case, the reproduced audio data output from the audio data processor 9 is converted into an analog audio signal by the D / A converter 14 and is connected to the speaker 16 or the headphone terminal (or the line output terminal) via the amplifier 15. May be output to T3.
In addition, the audio data processor 9 can output the digital audio signal as it is to an external device via the data bus 10 and the connector 11 via the data bus 30.

  In the present embodiment, data other than audio data can also be transmitted via the data interface 10. For example, audio-related data (character data file or image data file), which has been described as being recordable on the disk 20, can be captured via the data interface 10 and recorded on the disk 20. It is said.

The display unit 8 includes, for example, an LCD (Liquid Crystal Display), and is displayed by being driven by the display driver 7. The operation of the display driver 7 is controlled by the CPU 2 in accordance with required display contents.
In the present embodiment, as will be described later, files such as texts and images are recorded on the disc 20 after being managed as related information (audio related data) accompanying the audio data as a track. Is possible. In this embodiment, for example, as described later, when reproducing audio data as a track, display of these audio-related data can be performed on the display unit 8. .

The operation unit 6 is provided with various operators operated by the user in order to execute a required operation in the recording / reproducing apparatus 1. In the operation unit 6, an operation information signal corresponding to an operation performed on the operation element is transmitted to the CPU 2. The CPU 2 executes a required control process in response to the operation information signal transmitted from the operation unit 6. Thereby, the operation of the device according to the operation on the operation unit 6 is obtained.
Further, in this figure, among the operators in the operation unit 6, the reproduction key 21, the shuffle key 22, and the skip key 23 are shown as particularly related to the present embodiment. The playback key 21 is an operator for starting playback of audio data as a track recorded on the disc. The shuffle key 22 is an operator for setting the shuffle mode as a reproduction mode for reproducing audio data as a track. The shuffle mode will be described later. The skip key 23 is an operator for skipping a track to be reproduced next to the currently reproduced track in various reproduction modes, as will be described later.
In the recording / reproducing apparatus 1 of the present embodiment, a program mode is also provided as a track reproduction mode. Simply speaking, the program mode is a mode for reproducing a track arbitrarily selected by the user from the tracks recorded on the disc 20 in a desired reproduction order. Although not shown, the operation unit 6 is also provided with an operator for the user to set the contents of the program according to a predetermined operation procedure.

  Although not shown here, for example, a remote controller capable of performing the same operation as the operation unit 6 is provided, and a required operation in the recording / reproducing apparatus 1 is executed according to the operation performed on the remote controller. It may be configured as described above.

The CPU 2 executes control on each functional circuit unit, internal arithmetic processing, and the like in order to realize a required operation in the recording / reproducing apparatus 1.
The ROM 3 stores various necessary programs to be executed by the CPU 2 and various data necessary for the processing of the CPU 2.
The RAM 4 is a memory for holding a program read from the ROM 3 that should be used by the CPU 2 and data obtained by various control processes and arithmetic processes executed by the CPU 2. Here, in the RAM 4, a program setting area 4a in which information on the program reproduction order registered by the user is stored is set in correspondence with a program reproduction mode to be described later.

  The configuration shown in FIG. 1 is merely an example, and the configuration as a device to which the present invention is applied is not limited to this, and various modifications can be made.

2. Data recorded on the disc

For confirmation, the logical structure of data recorded on the disk 20 is simply shown in FIG.
As shown in FIG. 2A, the audio data is recorded on the disk 20 in units of tracks corresponding to each piece of music as described above. For example, tracks are managed so that track numbers are assigned as shown in tracks # 1 to #N as shown in the figure.
Then, as shown in FIG. 2B, audio related data (character data file or image data file) associated with each track is recorded. Audio-related data is also recorded so as to be managed in association with tracks # 1 to #N as shown in the figure.
It is supposed to be possible.

For the disc 20 on which data is recorded in this manner, in addition to reproducing and outputting the audio data recorded on the disc 20, the audio related data is also reproduced and output at a required timing, for example, displayed. It is possible.
Here, the audio-related data is, for example, information related to a song as a track, and if it is a character data file, for example, the title of the track, the title as an album including the track, the track The name of the player who is playing the song, the profile about the player, and the lyrics. As the image data file, an album jacket corresponding to the track, a photograph of a performer, a video clip-like moving image, and the like can be considered. These various types of file data are managed in association with tracks, for example, while the type contents can be identified.

3. Skip operation

In the recording / reproducing apparatus 1 according to the present embodiment, at least three modes of a normal mode, a shuffle mode, and a program mode are provided as reproduction modes for reproducing a track (audio data).

  The normal mode is a mode in which tracks are sequentially played back in accordance with, for example, all track track number orders managed and recorded as one album. For example, the operation unit 6 can be operated from the playback stopped state without any mode designation. When the reproduction key 21 is operated, the track reproduction in the normal mode is started.

  The shuffle mode is a mode in which, for example, all tracks managed and recorded as one album on the disc 20 are sequentially reproduced in a random track order. That is, when playback is performed by selecting the shuffle mode, the user can enjoy the listening to the playback sound in a different track playback order each time.

  As a reproduction procedure for setting the shuffle mode, for example, the user operates the shuffle key 22 of the operation unit 6 in a state where reproduction is stopped. Thereby, the shuffle mode is set as the reproduction mode. The fact that the shuffle mode is set is notified to the user, for example, by displaying on the display screen of the display unit 8. Thereafter, when the playback key 21 is operated, playback in the shuffle mode is performed.

The program mode is a mode in which, for example, one or more tracks arbitrarily selected by the user from all tracks managed and recorded as one album can be specified and played back by specifying an arbitrary playback order. is there.
As an operation for this, for example, a predetermined key operation for setting the program mode is performed on the operation unit 6 in a state where the reproduction is stopped. As a result, the track for program playback can be selected, so that the user can specify the track number to be played back in accordance with the desired playback order, for example, by operating a numeric key or the like provided on the operation unit 6. I will do it. Then, an operation for registration is performed by a predetermined operation. As a result, the playback order of the tracks specified by the previous operations is stored in the program setting area 4a of the RAM 4.
Thereafter, when the playback key 21 is operated, track playback is sequentially performed in accordance with the registered contents stored in the program setting area 4a. That is, program playback is performed.

  In the present embodiment, when the track reproduction is performed under each of the above reproduction modes, for example, a display as shown in FIG. Here, a display state example during shuffle playback is shown.

In FIG. 3A, first, a current track display area 40 in which information relating to the currently reproduced track is displayed is shown. In the current track display area 40, the track number currently being played back, the playback time, and the title of the music on the track are shown. Here, track # 6 is being played back, the current playback time is 3 minutes and 30 seconds, and the track title is shown as “NO PLACE LIKE HOME ...”. Here, as described above, the title of the music on the track is obtained by reproducing from the disc a character data file managed as a title as a type of the audio data related information corresponding to track # 6. Is.
In the current track display area 40, a playback mode display indicating the current playback mode is also performed. Here, characters "Shuffle" indicating the shuffle mode are displayed.

A next track display area 41 is shown below the current track display area 40. The next track display area 41 is a display area for notifying the user of a track (next track) to be reproduced next to the currently reproduced track. Normally, for example, in the past, when performing playback in the shuffle mode, the next track is not notified, but in this embodiment, it is also considered that it corresponds to the skip operation described later. Then, such a next track is displayed.
Here, as the display form of the next track display area 41, a track number (track # 2) and characters as its title (DO YOU KNOW...) Are displayed.

  In this way, in the present embodiment, information indicating what track is to be reproduced next to the currently reproduced track is displayed on the display unit 8, so that the user views this display. Thus, it is possible to grasp what the music to be reproduced next is.

  Here, for example, during the reproduction of the track # 6, the user looks at the next track display area 41 shown in FIG. 3A, and the next track shown here is not the user's preference, and the user can Suppose you wanted to skip without playing. In such a case, the user operates the skip key 23 in the operation unit 6.

  When the skip key 23 is operated, the setting of the track # 2 having the title “DO YOU KNOW...” Shown in the next track display area 41 in FIG. . Then, as shown in FIG. 3B, another track is newly set as the next track, and the display of the next track display area 41 is changed. Here, a state where a track # 4 titled “DID YOU KNOW...” Is displayed as a new next track is shown.

  For example, if the skip key 22 is further operated from the state shown in FIG. 3B, the track # 4 titled "DID YOU KNOW ..." is further skipped, and another track is newly added. The next track is selected and displayed on the next track display area 41.

The display form of the current track display area 40 and the next track display area 41 is substantially the same in the normal mode and the program mode. However, in the playback mode display 42, the display is changed to the content indicating the normal mode (or may not be displayed) if it is the normal mode, and the program mode if it is the program mode.
Even in the normal mode and the program mode, the previous next track is skipped by the operation of the skip key 23, and a new next track is displayed in the next track display area 41.

Further, in the present embodiment, when the skip key 23 is operated as described above, a track that has already been reproduced is excluded from the track candidates that are newly selected as the next track. And This applies not only to the shuffle mode but also to the normal mode and the program mode.
Therefore, if a skip operation is performed during playback in the normal mode, the track number next to the skipped track number is set as the next track.
In addition, when a skip operation is performed during playback in the program mode, a track registered to be played back next to the skipped track is newly selected as the next track.

  In addition, regarding the shuffle mode, it is a handling of a track that is skipped (skip) by the operation of the skip key 23. One of them is handled as being played back and is not played back by the subsequent shuffle playback. It is possible to do so. Also, as one, the skipped track is changed to the next track after the skip operation is performed and the next track is changed after the skip operation is performed. Can be considered.

As described above, in the present embodiment, it is possible to skip the next track by operating the skip key.
For example, in the past, in order to skip the playback of a track as a certain piece of music, in any playback mode, when playback of a track to be skipped is started, for example, It was necessary to perform a cue selection operation to send one track. In other words, during a period in which a track before the track to be skipped is being played, there is no operation function for skipping the track to be skipped in advance.
On the other hand, if the next track can be skipped as in the present embodiment, it is not necessary to wait for the playback of the currently playing track to end and the playback of the next track to start. Therefore, the convenience for the user is improved.
In particular, with respect to the shuffle playback mode, conventionally, the next track has not been presented to the user, and therefore the user has not been able to grasp in advance the track to be played next. On the other hand, in the present embodiment, in the shuffle mode, the next track is displayed as described with reference to FIG. 3 and the skip operation can be performed so that the user can perform the shuffle mode. In this case, at least the track to be played next can be known, and if the user does not like it, an operation for skipping the playback of the next track can be performed.

  The display form as the next track display area 41 is not limited to that shown in FIG. For example, if an image data file such as an album jacket is recorded on the disc 20 as audio-related data on the disc 20, such an image data file can be displayed. is there.

  Conversely, for example, as the information indicating the next track, as long as the track number is displayed, the user can know the music of the track with the track number. For this reason, in the present embodiment, the minimum necessary information for indicating the next track is a track number. However, as shown in FIG. 3, if information other than the track number such as an album title is presented, it is possible to more easily understand what kind of music the next track is. .

4). Processing action

Next, a processing operation for realizing a track skipping operation in accordance with the skip operation in each playback mode described above will be described with reference to the flowcharts of FIGS. This processing operation is executed by the CPU 2. Further, as processing operations described below, it is assumed that the playback mode is selected in the previous stage according to the predetermined operation procedure described above.

First, the CPU 2 waits for the operation of the reproduction key 21 in step S101 shown in FIG. 4, and when it is determined that the operation of the reproduction key 21 has been performed, the process proceeds to step S102. move on.
In step S102, the currently set playback mode is determined. If it is in the normal mode, the process proceeds to step S501 in FIG. In the case of the program mode, the process proceeds to step S701 in FIG. Further, in the case of the shuffle mode, by proceeding to step S103 in FIG. 4, track reproduction as the shuffle mode is performed thereafter.

In step S103, n = 1 (that is, the first) is set for a variable n indicating the reproduction order of tracks reproduced in the subsequent shuffle mode. Then, in the next step S104, a process for determining the track #a to be reproduced first (n = 1) is executed.
As a process of the CPU 2 at this time, for example, random numbers are generated with the track numbers of all tracks managed as one album in the disk 20 as candidates. If all the track numbers are from track # 1 to # 10, random numbers are generated using integers 1 to 10 as candidates in step S104, and the integers 1 to 10 obtained here are generated. One of the numbers a is determined as the track number #a.

  As described above, when the track #a is selected, the CPU 2 proceeds to step S105, and executes a control process for starting reproduction of the nth track #a. That is, the CPU 2 reads the audio data as the track #a recorded on the disk 20 and performs the necessary signal processing as described above with reference to FIG. Output as.

  In the subsequent step S105, a control process for displaying the reproduction status of the track #a on the display unit 8 is executed. In other words, for the track #a, for example, the display driver 7 is controlled so that the display mode as the current track display area 40 of FIG. At this time, the track number in the current track display area 40 is performed based on management information on the disc 20 that manages audio data in units of tracks. In addition, it is conceivable that the reproduction time display is performed using time information obtained by extracting, for example, a subcode inserted into audio data. Then, for a character as a title as a song, a title character data file as audio-related data of track #a is read from the disk 20, and control is performed so that characters are displayed according to the title character data file. This display is realized.

  In the subsequent step S107, it is determined whether or not the variable n is the same as the maximum track number. That is, it is determined whether or not the currently reproduced track is the last track to be reproduced. If an affirmative result is obtained, the process proceeds to step S112 to wait for the reproduction of the currently reproduced track #a to end. If the reproduction of the track #a is completed, the process proceeds to step S113. Thus, the reproduction of the audio data is stopped and this routine is exited.

On the other hand, if a negative result is obtained in step S107, it is determined that there are still tracks to be reproduced, and the process proceeds to step S108. In step S108, the process for determining the track #b to be reproduced n + 1 is executed. That is, a process for selecting the track number of the next track to be reproduced next to the currently reproduced track is executed.
In this case, the CPU 2 excludes the track numbers of the reproduced tracks (including the currently reproduced track) from the candidates, and generates a random number using the remaining track numbers as candidates. The value obtained here is determined as the track #b.

In the subsequent step S109, control processing is executed so that the next track display area 42 is displayed as shown in FIG. 3A for the track #b determined in step S108.
By the processing so far, for example, the display state of the display unit 8 as shown in FIG. 3A in the shuffle mode is obtained.

In the subsequent step S110, the process waits for the reproduction of the track #a (that is, the currently reproduced track) to end, and when the reproduction ends, the process proceeds to step S111.
In step S111, the variable n is incremented to n + 1. Also, track number management is performed so that track #b, which has been treated as the next track until now, is treated as track #a currently being reproduced. A value as track #a before this is handled as a reproduced track number.
Then, the process returns to step S105.

  By executing such processing, track playback (that is, shuffle playback) is performed in a random playback order that does not follow the track number, and the track playback progresses as shown in FIG. As shown, the playback status display (current track display area 40) regarding the currently played track and the display (next track display area 41) indicating what the next track is are performed.

  When the processing for shuffle playback shown as steps S103 to S113 in FIG. 4 is being executed, if the skip key 23 is operated, the interrupt processing shown in FIG. 5 is executed. Thus, the next track is skipped as shown in the transition from FIG. 3A to FIG. 3B.

  As the processing shown in FIG. 5, first, the process waits for the operation of the skip key 23 in step S201. If it is determined that the operation of the skip key 23 is performed, the process proceeds to step S202. To be. In step S202, a process for changing the track #b, which is the track number of the next track currently determined, is executed. This process is actually the process included in step S108 of FIG.

The process in step S202 is as shown in FIG. 6, for example.
In FIG. 6, first, in step S301, the current track #b is set as the track #c indicating the track number to be skipped.
In step S302, a setting process for excluding track #c from candidate track numbers for determining the next track is executed. In the subsequent step S303, the reproduced track number is also set to be excluded from the candidate track numbers for determining the next track. As a result, the track number of the track to be skipped and the track of the reproduced track is excluded as a candidate for determining the next track.

  In step S304, a new track #b (that is, the next track) is determined by generating random numbers for the track numbers remaining as candidates in the processing in steps S302 and S303.

  Here, following step S305, as the process of step S306, the track #c that has been skipped by the process of the previous step S301 and has been temporarily excluded from the next track determination candidates is used from the next time. It is set to be included in the candidate track number for determining the next track. The setting of the candidate track number for determining the next track is performed by using a predetermined area of the RAM 4, for example.

Then, when the processing so far is completed, the system controller proceeds to step S203 in FIG. This step S203 actually overlaps the process of step S109 shown in FIG.
As a result, the next track display area 41 of the display unit 8 is switched to the display of the track #b which is the next track newly determined in step S304. That is, from FIG. The display state transition shown in FIG. 3B is obtained.

  In this case, in the process shown in FIG. 6, the process of step S305 is executed, and in the subsequent process for determining the next track, the skipped track is shuffled. Will be treated as a candidate. That is, skipping is performed correspondingly only when a skip operation is performed, and in the subsequent shuffle playback, there is a possibility of playback.

On the other hand, step S202 in FIG. 5 is replaced with the process shown in FIG. 7 in place of the process shown in FIG. 6, so that once skipped tracks are not shuffled. It is also possible to do.
In FIG. 7, first, in step S401, the track #b currently determined as the next track is included as a reproduced track. Then, a setting is made so that the reproduced track number is excluded from the track numbers of the next track determination candidates.

In subsequent step S402, a random number is generated by the next track candidate set in step S401, and a process for determining a new track #b is executed.
Then, the process proceeds to step S203 in FIG.

In the processing shown in FIG. 6, the track to be skipped is reproduced in the subsequent shuffle reproduction. For example, as the user desires, the flow and the atmosphere in accordance with the order of the reproduction music during the shuffle reproduction. It is suitable for cases where emphasis is placed on. In other words, if you do not want to play the next track after the currently played song (track), but want to play the next track after a certain song later, this playback mode Becomes effective.
On the other hand, in the process shown in FIG. 7, a track once skipped will not be shuffled thereafter, so for example, a song (track) that the user does not want to listen to during shuffle playback in the album. It will be suitable when there is.
Then, as the process of step S202 in FIG. 5, it is conceivable that the process in FIG. 6 or 7 is set in advance on the device side in consideration of the user's actual usability, for example. . Alternatively, it may be possible to allow the user to arbitrarily select by a predetermined operation.

So far, the operation in the shuffle mode has been described.
On the other hand, if it is determined in step S102 in FIG. 4 that the normal mode is selected, the process proceeds to step S501 in FIG.
In step S501, a variable N indicating a track number is set to N = 1, and the process proceeds to step S502. In step S502, playback of track #N is started. Accordingly, at the stage of first transitioning to step S502, the reproduction of track # 1 is started.

In the subsequent step S503, display control is executed so that the track #N is displayed as the current track display area 40 of FIG.
In subsequent step S504, it is determined whether or not the variable N is N = the maximum track number. That is, it is determined whether or not the currently reproduced track is the last track.
If an affirmative result is obtained in step S504, the process proceeds to step S509 to wait for the reproduction of the currently reproduced track #N to be completed, and to the subsequent step S510 with the completion of the reproduction of the track #N. To stop playing the audio data. Then, this routine is exited.

On the other hand, if a negative result is obtained in step S504, and reproduction of all tracks is not completed, the process proceeds to step S505.
In step S505, the track # N + 1 having the track number following the currently reproduced track #N is set as the track #M indicating the track number as the next track, and the process proceeds to step S506.

  In step S506, display control is executed so that the track set as track #M is displayed in the next track display area as shown in FIG.

  In subsequent step S507, the process waits for the reproduction of the currently reproduced track #N to end. When the reproduction of the track #N is completed, in the subsequent step S508, the track #M that has been set as the next track so far is set to be handled as the track #N to be reproduced, The process returns to step S502.

  If the skip key 23 is operated while the normal mode playback process is being executed as shown in FIG. 8, the next track is skipped by executing the process shown in FIG. Is called.

In FIG. 9, first, it waits for the skip key 23 to be operated in step S601. If the skip key 23 is operated here, the process proceeds to step S602.
In step S602, the track #M that is currently set as the next track (when the skip key is operated) is processed as reproduced. Then, in the subsequent step S603, the track (# M + 1) of the number next to the track #M treated as being reproduced is handled as a new track #M.
Then, as the processing of the next step S604, display control is executed so that the track newly set as the track #M in the above step S604 is displayed as the next track display area 41. This is substantially a transition to the process of step S506 in FIG.

  By executing such processing, the track reproduction according to the track number order as the normal mode is performed. Also during the playback in the normal mode, the current track display area 40 and the next track display area 41 as shown in FIG. 3A are displayed. Then, according to the operation of the skip key 23, when a certain track is being reproduced, the next track can be skipped, and the track of the subsequent track number can be set as the next track. In response to this, the display content of the display unit 8 is also changed as described with reference to FIG. 3 (a) → FIG. 3 (b).

Next, processing operations corresponding to the program mode will be described.
If it is determined in step S102 in FIG. 4 that the program mode is set, the process proceeds to step S701 in FIG. 10 to execute processing for program mode reproduction.

In FIG. 10, first, in step S701, n = 1 (first) is set for a variable n indicating the playback order of tracks to be played back in the program mode. In step S702, a process for identifying the first (n = 1) th track #a to be reproduced is executed.
At this stage, as can be understood from the operation procedure described above, the program playback order information registered by the user by the program setting operation before operating the playback key 21 is already stored in the program setting area 4a of the RAM 4. It is in the stored state. In the process of step S702, the CPU 2 refers to the information content stored in the program setting area 4a to identify the track number as the track #a.

In the subsequent step S703, a control process for starting reproduction of the nth track #a is executed.
In subsequent step S704, along with the reproduction of track #a, display control is executed so that this track #a can be displayed as the current track display area 40 of FIG.

  In a succeeding step S705, it is determined whether or not the variable n matches the number of tracks registered in the program. That is, it is also determined here whether or not the track currently being reproduced is the last track to be reproduced. If an affirmative result is obtained, the process proceeds to step S709 to wait for the reproduction of the currently reproduced track #a to end. If the reproduction of the track #a is completed, the process proceeds to step S710. The playback of the audio data is stopped and the routine is exited.

On the other hand, if a negative result is obtained in step S705, it is determined that there are still tracks to be reproduced, and the process proceeds to step S706. In step S706, referring to the program setting area 4a of the RAM 4, a process for determining the track #b to be reproduced n + 1 is executed. That is, a process for selecting the track number of the next track to be reproduced next to the currently reproduced track is executed.
In this case, in principle, the CPU 2 treats the currently reproduced track and the previously reproduced track as a reproduced track, and the currently reproduced track from among the tracks that have not been programmed yet. Next, the track registered to be reproduced is determined as track #b.

In the subsequent step S707, control processing is executed so that the next track display area 42 shown in FIG. 3A is displayed for the track #b determined in step S706.
Through the processing so far, for example, even when track reproduction is performed in the program mode, the display state of the display unit 8 as shown in FIG. 3A can be obtained.

In the subsequent step S708, the process waits for the reproduction of the track #a (the currently reproduced track) to end, and when the reproduction ends, the process proceeds to step S711.
In step S711, the variable n is incremented to n + 1. Also, numerical value replacement processing is performed so that the track #b that has been treated as the next track so far is treated as the currently reproduced track #a. A value as track #a before this is handled as a reproduced track number. Then, the process returns to step S703.

  Through the processing as described above, program reproduction is performed, and the display shown in FIG. 3A is performed as the track reproduction progresses.

  The skip process is performed when the skip key 23 is operated during the track reproduction in the program mode. This process may be performed in accordance with the process of FIG. 5 shown as the skip process in the previous shuffle mode. However, in program playback, the track playback order is determined according to the registered contents, so there is no need to include the skipped track as a candidate for determining the next track to be executed later. It is thought that there is nothing in particular. Therefore, the processing in step S202 in FIG. 5 may be configured to execute the processing operation shown in FIG.
