Description

  The present invention relates to a playback apparatus, a playback program, and a playback method that perform playback based on a erasable file recorded on a recording medium.

  In general, an apparatus that reproduces music based on an audio file stored on a hard disk or the like has a mode for performing trick play. Trick play means special reproduction such as random play, repeat play, and scan play, which is different from normal reproduction.

  In these trick plays, if the sound file being played is deleted, the subsequent trick play is hindered. Therefore, conventionally, when the file is deleted by the user during the trick play, the trick play is canceled. Alternatively, access restrictions are provided so that the file cannot be deleted during trick play. Alternatively, if the file is to be deleted during trick play, a warning screen is displayed, and if the file is deleted, a warning that the trick play is canceled is displayed.

  Specifically, for example, when an audio file to be played is deleted during one song repeat play, repeat play is canceled or repeat play is continued for the next song. In addition, during random play, if an audio file of any song in a folder that is a play target is deleted, random play is canceled. Further, when the audio file of any music in the folder to be scanned is deleted during the scan play, the scan play is canceled.

  As prior art related to trick play, for example, when recording a video signal, two types of encoded data for forward variable speed reproduction and reverse variable speed reproduction are generated and recorded. Are known for use in forward variable speed playback and reverse variable speed playback, respectively (see, for example, Patent Document 1). Further, Patent Document 2 discloses a technique related to switching of data for normal reproduction and various trick play of a program stored in a storage device.

Also, when playing back the digital video / audio data recorded on the recording medium, the playback control information is created and stored in the storage means, and in response to a data playback restart instruction from an arbitrary playback position issued after the playback of the recording medium is completed. A technique is known in which reproduction control information in a storage unit is retrieved, and reproduction from an arbitrary reproduction position on a recording medium can be resumed based on the retrieved reproduction control information (for example, Patent Document 3). reference).

  However, as described above, canceling trick play based on the deletion of an audio file being played back prevents subsequent trick play from being performed, and thus a user who will continue trick play. Will betray you. For example, if an audio file being played is deleted during one song repeat play, the repeat expectation is canceled or the target song for repeat play is automatically changed to the next song. It will be betrayed.

  In addition, when the play is canceled based on the fact that the audio file being played is deleted during random play or scan play, the user is deprived of the opportunity to listen to all the songs in the folder that was the play target. In order to avoid this and continue the play, the user must perform an operation of excluding the music to be deleted from the one-round management table.

  Also, once you delete an audio file, you will not be able to listen to the end of the song, so it is inconvenient if you want to decide whether to delete it after listening to the end. There is also a problem.

  In view of such problems of the prior art, the first object of the present invention is to perform file playback by a user during trick play when performing playback based on a removable file recorded on a recording medium. Even in the case of deleting, the expectation of the user is not impaired by the release of trick play or the change of the music to be played.

  A second object of the present invention is to determine whether or not to delete a song after the user has listened to the end of the song when performing playback based on the deleteable file recorded on the recording medium. The object is to provide a convenient means to make a judgment.

  In order to achieve the first object, a playback apparatus according to the present invention deletes a file being played back in trick play in a playback apparatus that performs playback based on a deleteable file recorded on a recording medium. Trick play continuation setting means is provided for accepting a setting as to whether or not to continue the trick play when an instruction or a file based on the instruction is deleted.

  Here, examples of the recording medium include a hard disk, a CD-R, a CD-RW, a DVD + RW / + R, and a DVD-R / RW. As the file, for example, a file in each format such as WAVE, WMA, MPEG, AVI and the like is applicable. Examples of trick play include random play, repeat play, scan play, fast forward playback, fast reverse playback, and slow playback.

  Conventionally, when there is an instruction to delete a file being played in trick play, the file is deleted and the trick play is canceled, or the next file is used if the trick play is one-track repeat playback. In this way, one-track repeat playback is automatically continued. For this reason, there is a possibility that the user's expectation may be lost because the trick play is interrupted or repeat reproduction is performed for an unintended song.

  On the other hand, according to the present invention, since the user can set whether or not to continue trick play even if the file being played back by trick play is deleted by the trick play continuation setting means, the expectation is lost. Can be avoided.

  The playback device according to a second aspect of the present invention is the playback device according to the first aspect of the present invention, wherein when the file deletion instruction or the file deletion based on the instruction is made, the trick play is continued based on the setting content by the trick play continuation setting means Or it has the means to perform cancellation | release, It is characterized by the above-mentioned.

  According to a third aspect of the present invention, there is provided a playback apparatus according to the first or second aspect, further comprising: a playback end deletion unit that deletes the designated file when the playback of the file ends.

  According to a fourth aspect of the present invention, there is provided a playback apparatus according to the third aspect of the present invention, wherein the specified file is deleted when the deletion instruction is given or when the reproduction of the file is completed. It has a deletion reservation setting means.

  According to a fifth aspect of the present invention, in the third or fourth aspect, the playback apparatus accepts an instruction for confirming whether or not the deletion is actually executed before executing the deletion of the file at the time when the playback ends. It is characterized by having.

  A playback device according to a sixth invention is characterized in that, in the fourth or fifth invention, when a file being played back in trick play is changed, the file is not deleted when the playback is finished. To do.

  In any one of the first to sixth inventions, the playback device according to the seventh invention provides a file deletion instruction or a file deletion based on the instruction when setting to continue trick play is made. Is performed, trick play is continued using a file other than the deleted file.

  According to an eighth aspect of the present invention, there is provided a playback apparatus according to any one of the first to seventh aspects, wherein the file is deleted when the trick play is one-track repeat playback and the trick play is set to continue. Or deleting a file based on the instruction, trick play is continued using the next file after the deleted file.

  In order to achieve the second object described above, a playback device according to a ninth aspect of the present invention deletes a file being played back in a playback device that performs playback based on a deleteable file recorded on a recording medium. And a means for executing deletion of the file when the reproduction of the file is completed.

  A reproduction program according to a tenth invention causes a computer to function as each unit constituting any one of the first to ninth reproduction apparatuses.

  According to an eleventh aspect of the present invention, in order to achieve the first object described above, a reproduction method for reproducing based on a erasable file recorded on a recording medium is a method for reproducing a file being reproduced in trick play. The method includes a step of accepting an instruction to delete or setting of whether or not to continue trick play even when a file is deleted based on the instruction.

  A playback method according to a twelfth aspect of the present invention is a playback method for performing playback based on a deletable file recorded on a recording medium in order to achieve the second object described above, wherein the file being played is deleted. When the instruction is issued, the deletion of the file is performed when the reproduction of the file is completed.

  According to the present invention, it is possible to make settings so that trick play can be continued without any trouble even when a file being played back in trick play is deleted. Further, it is possible to finally determine whether or not to delete the reproduced file after viewing the reproduction result to the end.

  FIG. 1 is a block diagram showing the configuration of a playback apparatus according to an embodiment of the present invention. As shown in the figure, this apparatus controls the various parts of the apparatus and performs data processing, reproduces music based on audio data recorded on the hard disk, and displays information for display on the main microcomputer 1. A hard disk device 2 to be transferred to the storage unit, a storage unit 3 for storing setting data based on a user instruction, a display unit 4 for displaying information to be provided to the user based on a command from the main microcomputer 1, and a user Includes an input unit 5 for performing an input operation on the main microcomputer 1.

  The audio data recorded on the hard disk has an audio file format such as MP3 or WAVE. The input operation by the user includes, for example, an operation for turning on / off the setting of trick play continuation and the setting of deletion reservation in addition to conventional operations such as starting and releasing trick play and deleting an audio file.

  The trick play continuation setting means setting whether or not to continue without releasing the trick play even when the sound file of the music being reproduced in the trick play is deleted. Deletion reservation is a setting for whether or not to perform the deletion after the end of playback without performing the deletion immediately when there is an instruction to delete the audio file of the music being played in trick play. Means.

  Trick play includes one-track repeat play, random play, scan play, and the like. The display on the display unit 4 includes a display relating to a trick play state and a reproduction state such as a time code. The storage unit 3 can be configured by a RAM or the like, and the storage content includes information on the setting content for trick play continuation and deletion reservation.

  FIG. 2 is a flowchart showing a part of processing (hereinafter referred to as “first processing”) performed by the main microcomputer 1. The first process is repeated at predetermined intervals during the trick play period.

  When the first process is started, first, in step 21, it is determined whether or not to release the trick play. For example, when the user performs an operation for canceling trick play or an operation for replacing a disc, it is determined that the trick play is cancelled. If it is determined that the trick play is to be cancelled, the process proceeds to step 22, and if it is determined not to cancel the trick play, the process proceeds to step 23.

  In step 22, trick play is canceled and the normal playback mode is entered, and the first process is terminated. When the normal playback mode is entered, the music is sequentially played from the next music after the music played in the trick play mode. As the next song, for example, the next song in the index of the folder or the playlist in which the song that has been reproduced by trick play is present corresponds.

  In step 23, it is determined whether or not an operation for deleting a performance song has been performed. If it is determined that the deletion operation has not been performed, the first process is terminated. If it is determined that the deletion operation has been performed, the process proceeds to step 24, where it is determined whether the deletion reservation setting is on or off. If it is determined that the deletion reservation setting is ON, the process proceeds to step 25 without deleting the audio file of the performance song being played (hereinafter, the audio file name of this song is referred to as “Song A”). The deletion reservation flag is set to ON, “Song A” is stored, and the first process is terminated. Even after the processing is completed, the reproduction of the music piece A is continued.

  If it is determined in step 24 that the deletion reservation setting is OFF, the process proceeds to step 26 to determine whether or not the trick play continuation setting is ON. If it is determined that the trick play continuation setting is off, the process proceeds to step 27, the sound file of the song A is deleted to cancel the trick play, and normal playback is started from the next song, and the first process is performed. finish. As the next song, for example, the next song in the index of the folder or the playlist in which the song that has been reproduced by trick play is present corresponds.

  If it is determined in step 26 that the trick play continuation setting is on, the process proceeds to step 28, the sound file of the song A is deleted, and the first process is terminated. Trick play continues even after the end of processing. That is, for example, when the trick play is one-track repeat playback, one-track repeat playback is continued for the next song. When the trick play is random reproduction, the music selected at random is reproduced next.

  FIG. 3 is a flowchart showing another part of the processing performed by the main microcomputer 1 (hereinafter referred to as “second processing”). The second process is also repeated at a predetermined interval during the trick play period together with the first process.

  When the second process is started, first, in step 31, it is determined whether or not to release trick play. For example, when the user performs an operation for canceling trick play or the like, it is determined to cancel the trick play. If it is determined that the trick play is not canceled, the process proceeds to step 33. If it is determined that the trick play is to be cancelled, the trick play is canceled in step 32, and after the transition to the normal playback mode, the second process is terminated.

  In step 33, it is determined whether or not the target song or folder for trick play has been changed by an operation such as track-up. If it is determined that the target has been changed, the deletion reservation flag is set to OFF in step 34, the storage of “Song A” performed in step 25 in FIG. 2 is discarded, and the second process is terminated. Trick play is continued using the new song.

  If it is determined in step 33 that the target has not been changed, the process proceeds to step 35, where it is determined whether or not the reproduction of the music piece A is completed and the deletion reservation flag is on. If the determination result is negative, the second process is terminated. Trick play will continue. If the determination result is affirmative, the process proceeds to step 36, the deletion reservation flag is set to OFF, the storage of “Song A” is discarded, and the process proceeds to step 37.

  In step 37, a message requesting an instruction as to whether or not the song A can be deleted is displayed on the display unit 4 to accept the user's instruction, and it is determined whether or not to delete the song A based on the instruction content. To do. During this time, the playback operation for the next song is paused. The reason for requesting confirmation of deletion in this way is that there is a possibility that the user is not willing to delete the song A when the user has finished listening to the song A.

  If it is determined in step 37 that song A is not deleted, the process proceeds to step 39. If it is determined in step 37 that music A is to be deleted, music A is deleted in step 38, and then the process proceeds to step 39. In step 39, it is determined whether or not the trick play continuation setting is ON. If the setting is on, the second process is terminated.

  In this case, trick play is continued. That is, for example, when the trick play is one-track repeat playback, one-track repeat playback is continued for the next song. When the trick play is random reproduction, the music selected at random is reproduced next.

  If it is determined in step 39 that the trick play continuation setting is off, the trick play is canceled in step 40, the normal playback mode is entered, and the second process is terminated. When transitioning to the normal playback mode, playback starts from the song next to song A.

  FIG. 4 shows a setting screen for trick play continuation setting and deletion reservation setting. FIGS. 9A to 9D show setting screens in different setting states. That is, the setting states for the trick play continuation setting and the deletion reservation setting are both on in the screen of FIG. 10A, off and on in the screen of FIG. 10B, and on in the screen of FIG. And off, and both are off in the screen of FIG. In each setting state, if the music of track 3 stored in the hard disk is played and one song repeat playback is performed as a trick play, according to the processing of FIG. 2 and FIG. Depending on the operation, the playback device operates as follows.

  That is, in the case of the setting state of FIG. 9A, when the user performs an operation to delete the track 3, the deletion reservation mode is on, so the deletion of the track 3 is not immediately executed (step 23, 24, 25), it becomes a reserved form and is performed when the reproduction of the track 3 is finished (step 38). Therefore, the user can listen to the music on track 3 to the end. However, if the user changes the target of one-track repeat playback from the song on track 3 to another song, the deletion reservation for track 3 becomes invalid (steps 33 and 34), and the deletion is not executed.

  When the reproduction of the track 3 is finished, the reproduction is paused and a message confirming the intention to delete is displayed, so that the user can instruct execution or withdrawal of the track 3 (step 37). In either case of execution or withdrawal, since the trick play continuation mode is on, one-track repeat reproduction is started for the next track 4.

  On the other hand, in the case of the setting shown in FIG. 5B, when the user performs an operation to delete the track 3, since the deletion reservation mode is on, the deletion of the track 3 is not executed immediately (steps 23, 24, 25) It becomes a reserved form and is performed when the reproduction of the track 3 is completed (step 38). Therefore, the user can listen to the track 3 to the end. However, if the user changes the target of one-track repeat playback from the song on track 3 to another song, the deletion reservation for track 3 becomes invalid (steps 33 and 34), and the deletion is not executed.

  When the reproduction of the track 3 is finished, the reproduction is paused and a message confirming the intention to delete is displayed, so that the user can instruct execution or withdrawal of the track 3 (step 37). In either case of execution or withdrawal, since the trick play continuation mode is off, the one-track repeat reproduction is canceled, the normal reproduction is started, and the normal reproduction is started from the next track 4.

  Further, in the case of the setting shown in FIG. 5C, when the user performs an operation for deleting the track 3, the deletion reservation mode is off, so that the deletion of the track 3 is immediately executed (steps 23, 24, 27, 28). Since the trick play continuation mode is on, the one-track repeat reproduction is continued for the next track 4 (step 28).

  In the case of the setting shown in FIG. 6D, when the user performs an operation of deleting the track 3, the deletion reservation mode is off, so that the deletion is immediately executed (steps 23, 24, 27, 28). ). Since the trick play continuation mode is off, the one-track repeat playback is canceled, the normal playback is started, and playback is started from the next track 4.

  By the way, in the case of performing random play or scan play, the once-reproduced music is excluded from the reproduction target until the reproduction of all the music to be played is completed. For example, if there are five tracks 1 to 5 to be played, in the case of random play, the track numbers are reproduced as 3 → 1 → 5 → 2 → 4, and in the case of scan play, 3 The reproduction is performed once for each track such that the reproduction is performed in the order of 4 → 5 → 1 → 2, and the reproduction for the next round is performed after completing the round for all the target tracks.

  FIG. 5 shows a setting screen for random play continuation and deletion reservation. In the figure, the random play continuation setting is on and the deletion reservation setting is off. In this case, after the user plays the track 3 and starts random play, when the user performs an operation to delete the song being listened to, the deletion reservation setting is off, so the deletion is executed immediately, and the track 4 Playback is started (steps 23, 24, 26, 28). That is, since the random play continuation setting is on, the random play is continued from the track 4.

  FIG. 6 shows a setting screen for scan play continuation and deletion reservation. In the figure, the scan play continuation setting is on and the deletion reservation setting is off. In this case, if the user performs an operation of deleting the song being listened to after playing the track 3 and starting the scan play, the deletion is immediately executed because the deletion reservation setting is off (step 23, 24, 26, 28), the reproduction of the track 4 is started. That is, since the scan play continuation setting is on, the scan play is continued from the track 4.

  According to the present embodiment described above, by setting trick play continuation on or off, it is possible to determine in advance whether or not to continue trick play when deleting a song being played in trick play mode. .

  Also, if trick play continuation is set to ON, even if the song being listened to is deleted, the trick play is continued from the next song, so that it is possible to save the trouble of setting the trick play again. .

  Also, by setting the deletion reservation on or off, when deleting a song being played in trick mode, it is possible to determine in advance whether to delete immediately or after the end of playback of the song.

  In addition, when the deletion reservation setting is on, playback of the song to be deleted ends, and the deletion intention is reconfirmed when the deletion is executed. Can be canceled.

  Note that the present invention is not limited to the above-described embodiment, and can be implemented with appropriate modifications. For example, in the above description, the case where the audio file stored in the hard disk is reproduced as the target is described, but the present invention is also applied to the case where the reproduction is performed on the MPEG file recorded on the DVD instead. Can do.

  Further, in the above description, the case where one song repeat play, random play, and scan play are performed as trick play has been described, but the present invention is also applied to the case where other trick play such as fast-forward playback is performed instead. can do.
