Description

  The present invention relates to a scan reproduction control apparatus, method, and program for searching for content desired to be edited by scan reproduction.

  Some audio apparatuses are equipped with a scan reproduction function for reproducing a predetermined part, typically an intro part, of each music piece in order for a plurality of music pieces recorded on a recording medium. In such an audio device with a scan playback function, the user plays back the music in the recording medium in order using the scan playback, and when the music desired to play flows, the user issues a playback instruction for the music. The whole can be heard.

  The user may also wish to edit a predetermined song in the recording medium. In such a case, the audio device with a predetermined scan reproduction function allows the user to use the scan reproduction, and the user operates the edit key when the music desired to be edited is reproduced by the scan reproduction. Then, editing of the music is started.

  In the conventional audio apparatus, when a desired music is found by scanning reproduction and the editing mode for the music is entered, the scanning reproduction ends. Therefore, the user cannot hear the playback sound of the music while editing the music, and when scanning playback is resumed after editing is completed, the user needs to re-operate the scan playback key. Regardless of the finished music, the scan reproduction is performed again from the music whose reproduction order is No. 1 in the scan reproduction.

On the other hand, in Patent Document 1, in an audio system, a user performs scan reproduction for all music pieces on a CD (S20 → S21 → S22 → S23 → S26 → S27 → S20 → in FIG. 3 of Patent Document 1). ..), searching for a music to be dubbed, and when the music is found, press the one-music playback key or the REC key (S25 in FIG. 3 and S43 in FIG. 4) or press the one-music dubbing key (S85 in FIG. 10 of Patent Document 1), dubbing is performed, and after dubbing is completed, scanning reproduction is resumed from the music next to the dubbing music (S32 → S26 → S27 in FIG. 1 of Patent Document 1). S20 → S21 and S97 → S98 → S99 → S86 → S87 → S80 → S81 in FIG.

  There may be multiple pieces of music that the user desires to edit in the music to be scanned and reproduced. In a conventional audio device with a scan playback function, the user must operate the scan playback key again, and in the scan playback after completion of editing, playback starts from the first music piece. It takes time for the music to be played by scan playback.

  Patent document 1 is a scan reproduction for dubbing music search, which is different from music editing. When editing music, processing outside the recording medium or folder containing the music to be scanned and reproduced, such as copying or moving the file of the music, is excluded, and the processing remains within the same recording medium or folder. .

  An object of the present invention is to provide a scan reproduction control apparatus, method, and program that enable a user to efficiently find and edit an editing target content.

  According to the present invention, when a user finds content to be edited by scanning reproduction, edits the content, and finishes editing, scanning reproduction is automatically resumed. In the scan reproduction, scan reproduction is performed from a predetermined content whose scan reproduction order is within a predetermined number before and after the edited content.

The scan reproduction control apparatus according to the present invention includes an edit mode start instruction detecting means for detecting an edit mode start instruction from a user during a scan reproduction period in which a plurality of contents are partially reproduced in order, and the edit mode start instruction detecting means starts the edit mode. When an instruction is detected, an edit mode start means for starting an edit mode for the content that is being partially reproduced at that time, and an edit mode end instruction for detecting an edit mode end instruction during a period when the edit mode start means has entered the edit mode When the instruction detection means and the edit mode end detection means detect the edit mode end instruction, the edit mode is ended, scan reproduction is started from the content to be edited in the edit mode, and scan reproduction of the content to be edited is performed. Time, playback order Scan reproducing means shorter than the scan duration for each content that is later than the content to be edited provided with.
Another scan reproduction control apparatus according to the present invention includes an edit mode start instruction detection unit that detects an edit mode start instruction from a user during a scan reproduction period in which a plurality of contents are partially reproduced in order, and the editing mode start instruction detection unit performs editing. When a mode start instruction is detected, an edit mode start means for starting an edit mode for the content that is being partially played at that time, and an edit that detects an edit mode end instruction during the period when the edit mode is started by the edit mode start means When the editing mode end instruction is detected by the mode end instruction detecting unit and the editing mode end detecting unit, the editing mode is ended, and the predetermined content determined based on the type of editing in the editing mode, the content to be edited More Scan playback means for starting scan playback from the content and shortening the scan playback time of the content whose scan playback order is before the content to be edited shorter than the scan playback time of each content whose playback order is after the content to be edited .

The scan reproduction control method of the present invention includes an edit mode start instruction detecting step for detecting an edit mode start instruction from a user in a scan reproduction period in which a plurality of contents are partially reproduced in order, and an edit mode start in the edit mode start instruction detecting step. When an instruction is detected, an edit mode start step for starting an edit mode for the content that is being partially reproduced at that time, and an edit mode end instruction for detecting an edit mode end instruction during the period when the edit mode is entered by the edit mode start step When an edit mode end instruction is detected in the instruction detection step and the edit mode end detection step, the edit mode ends, scan playback starts from the edit target content in the edit mode, and the scan of the edit target content starts. The down playback time, including scan regeneration step, be shorter than the scan duration for each content that is later than the content playback order is edited.
In another scan reproduction control method of the present invention, an edit mode start instruction detecting step for detecting an edit mode start instruction from a user in a scan reproduction period in which a plurality of contents are partially reproduced in order, and an edit in the edit mode start instruction detecting step When a mode start instruction is detected, an edit mode start step for starting an edit mode for the content that is being partially played at that time, and an edit for detecting an edit mode end instruction during the period when the edit mode is entered by the edit mode start step When the edit mode end instruction is detected in the mode end instruction detection step and the edit mode end detection step, the edit mode is ended, and the predetermined content determined based on the type of editing in the edit mode, the content to be edited More love Scan playback of the content whose scan playback order is before the content to be edited is scanned and playback of each content whose playback order is after the content to be edited is started. A scan reproduction step of making the time shorter than the time.

  The program of the present invention causes a computer to function as each unit of the scan reproduction control device of the present invention.

  According to the present invention, in the scan playback that automatically restarts after the user exits the edit mode, the scan playback is performed from the predetermined content whose scan playback order is within a predetermined number before and after the edited content. Become. As a result, the content partially reproduced in duplicate is sufficiently reduced, and a plurality of contents can be efficiently searched and edited by scanning reproduction.

  FIG. 1 is a configuration diagram of the system component 10. The selector 11 selects one of the analog signals from the CD mechanical unit 12 and the analog input terminal 13 based on the control signal from the system microcomputer 14 and outputs it to the ADC 21. The CD mechanism unit 12 sends the data read from the CD loaded therein to the DSP 22 as a digital signal and sends it to the selector 11 as an analog signal. The ADC 21 converts the analog signal from the selector 11 into a digital signal and outputs it to the DSP 22.

  The display unit 15 displays information such as text based on display data from the system microcomputer 14. The operation unit 16 is equipped with various keys, and outputs information related to the key operated by the user to the system microcomputer 14. The system microcomputer 14 performs a predetermined process based on inputs from the operation unit 16 and the DSP 22 and outputs a control signal to the selector 11 and the display unit 15.

  The DSP 22 executes various operations such as encoding and decoding while using the external RAM 23. The system component 10 includes a memory card slot 24 and a USB controller 26, and the memory card 25 and the USB memory 27 are detachably attached to the memory card slot 24 and the USB controller 26, respectively. The memory card 25 is, for example, an SD card or a memory stick.

  The audio files (typically music files) such as MP3 and WMA stored in the memory card 25 and the USB memory 27 being mounted are read by the DSP 22, decoded, and sent to the DAC 31. The DAC 31 converts a digital audio signal into an analog audio signal. The analog audio signal from the DAC 31 is amplified by the amplifier unit 32, then sent to the speaker 33, converted into corresponding audio by the speaker 33, and output.

  Instead of the USB memory 27, the USB controller 26 can be connected to a parent connector of a USB cable. Thereby, a portable digital audio player or the like is appropriately connected to the system component 10 via the USB cable. The system component 10 may incorporate a hard disk. The memory card 25, the USB memory 27, the built-in hard disk, the flash memory built in the portable digital audio player, or the like itself is a recording medium that can read and write data, or is equipped with a recording medium. The system component 10 can perform scan reproduction and editing for a recording medium that is connected, mounted, or built-in.

  2 to 6 show the entire flowchart of the scan reproduction control method 40 in a divided manner. The scan reproduction control method 40 is applied to the system component 10 of FIG. The recording medium to be scanned and reproduced in the system component 10 is not only the memory card 25, the USB memory 27, or the built-in hard disk device, but also can be built in or detached from a portable digital audio player connected to the system component 10 by cable or wirelessly. It may be a recording medium to be mounted.

  When the recording capacity of the recording medium is large and the number of recorded songs is enormous, all the songs recorded on the recording media to be scanned and played are not subject to scanning and played based on user specifications. It is also possible to narrow down to a range, for example, only songs in a predetermined folder or only songs having a file number within a predetermined range. The user operation on the system component 10 is not limited to the operation unit 16 provided in the main body of the system component 10, and may be performed via a remote controller.

  In the scan reproduction control method 40, when the reproduction sound of the desired music flows from the speaker 33, the user presses the confirmation key (positive in S50 in FIG. 3), and the predetermined music of each music such as the intro part of the music is selected. Following the playback of a part, the music is played to the end, or the editing key is pressed (the correct in S52 in FIG. 3), and predetermined editing (deletion or name change of the music file, etc.) is performed on the music. You can go. In the scan reproduction control method 40, the reproduction sound of the music is kept flowing from the speaker 33 until the end of the period when the user is editing the music (S66 → S67 → S60 << in FIG. 4). Or, S66 → S60 >> S64 → S66). When the user's editing work on the editing target music is prolonged and the music being edited is played back to the end, the music is returned to the beginning and the playback of the music is repeated (FIG. 4). S66 → S67). The reproduction part of each music piece by scan reproduction in this embodiment will be described as reproduction of an intro part as an example.

  In the flowchart section of FIG. 2, in S41, it is determined whether or not the user has input (operated) the scan reproduction key. If there is an input, the process proceeds to S42. In S42, it is determined whether or not there is a reproduction medium (recording medium to be scanned and reproduced). If there is, the process proceeds to S43, and if not, the process returns to S41. When there are a plurality of recording media that are candidates for scan reproduction, the user can select which scan reproduction media this time is to be used.

  In S43, the data of the file arrangement that determines the reproduction order of the scan reproduction is read from the recording medium, and when the reading is completed, the process proceeds to S44. The reproduction order of the music in the scan reproduction is the order of the file number, and the order of the file number corresponds to, for example, the order of the addresses of the files. When the folder on the recording medium has a tree structure, the folder and the music file occupy positions of nodes and leaves of the tree structure, respectively. If the file is distributed in multiple levels of the tree structure, instead of changing the file number order to the address order of each file, the deeper the file, the faster the playback order, It is also possible to make the playback order earlier in the shallower file.

  In the flowchart section of FIG. 3, in S50, it is determined whether or not a user operation has been performed on the confirmation key. If the determination is positive, the process proceeds to S51, and if not, the process proceeds to S52. The confirmation key is operated when the user desires to reproduce all of the music currently playing the intro part. In S51, subsequent to the intro portion of the music that plays sound when the enter key is operated, the subsequent playback is continued.

  In S52, it is determined whether or not a user operation has been performed on the edit key. If the determination is positive, the process proceeds to S53, and the edit mode is started. If not, the process proceeds to S54. In S54, it is determined whether or not the playback time for the music currently being played from the speaker 33 has reached a certain time. If the determination is positive, the playback of the intro portion for the music has ended. , The process proceeds to S70 (FIG. 5), and if not, the process returns to S50 and the reproduction of the intro part for the music is continued.

  In the flowchart section of FIG. 4, in S60, it is determined whether or not a user operation has been performed on the edit execution key. If the determination is positive, the process proceeds to S61, and if not, the process proceeds to S64. The edit execution key is pressed when the user confirms the content of editing performed on the music to be edited. In S61, the scan reproduction of the content for which the intro part is being reproduced is stopped.

  In S62, the file number (file No.) of the music (the music is recorded as an audio file on the recording medium) for which the editing content has been determined in S60 is stored. For convenience of explanation, it is assumed that the file number = n. This file number = n is used in later-described S81, S86, S88, S90 (FIG. 6) and the like. In S63, the confirmed editing content is recorded on the recording medium.

  In S64, it is determined whether or not a user operation has been performed on the edit cancel key. If the determination is positive, the process proceeds to S65, and if not, the process proceeds to S66. After depressing the edit key in S52 (FIG. 3), the user depresses the edit cancel key when canceling editing of the corresponding music or returning to the original scan reproduction without editing.

  In S65, it is determined whether or not the music being played when the edit cancel key is pressed is played for a certain period of time, that is, whether or not the intro part has been played. If the determination is positive, the process proceeds to S70 (FIG. 5). If NO, return to S50. The fixed time is, for example, in the range of 5 to 15 seconds.

  In S66, it is determined whether or not the audio file (musical piece) has been played to the end. If the determination is positive, the process proceeds to S67, and if not, the process returns to S60. In S67, the process returns to the head of the audio file (musical piece) currently being reproduced, and the reproduction of the file is repeated. As described above, in the scan reproduction control method 40, the user can reproduce the music while editing the music, and the user can edit the music while listening to the music. The music is played not only from the intro part but also from the beginning to the end of the music. Further, when the user edit for the music is prolonged and played back to the end of the music, the music returns to the top of the music and the playback continues.

  In the flowchart section of FIG. 5, in S70, it is determined whether or not the audio file that has finished playback of the intro part in S65 (FIG. 4) is the last file in the scan playback order. Go ahead and stop scan playback. If the determination in S70 is negative, the process proceeds to S72 to start scan reproduction of the next audio file.

In the flowchart section of FIG. 6, in S78, data for determining the playback order of the music in the scan playback is read (read) from the recording medium, and it is determined whether or not the reading is completed in S79, and as soon as the determination becomes positive, Proceed to S80. Through S78 and S79, the reproduction order of the music in the scan reproduction is updated. The reason for the update is that the edit includes deletion of the audio file (S80), combination (S87), or division (S89), etc., which involves a change in the total number of music pieces to be played back and the file number. , S86, S88, S90, the starting music becomes inappropriate when the starting music is determined, and this is prevented. In the scan reproduction control method 40, as can be understood from S60 →... → S63 in FIG. 4, every time the editing of each audio file is completed, the edited content is recorded on the recording medium. As a result, in S78, the data for determining the playback order of the scan playback is re-read from the recording medium, so that the playback start of the music and the subsequent playback order become appropriate in the scan playback after the editing.

  In S80, it is determined whether or not the type of editing performed by the user in the editing mode in S53 of FIG. 3 is file deletion. If the determination is positive, the process proceeds to S81 and corresponds to the file with file number = n. Scan playback starts from the music to be played. The file number (= n) assigned to the file by deleting the file becomes that of the next file with respect to the file, and scanning reproduction is started from the next music. If the determination in S80 is no, the process proceeds to S85.

  In S85, it is determined whether or not the type of editing performed by the user in the editing mode in S53 of FIG. 3 is a file name change. If the determination is positive, the process proceeds to S86, and the file number = n + 1 is set. Scan playback starts from the corresponding music. In this case, the file with the file number = n + 1 becomes the next file with respect to the file edited in S53, and scanning reproduction is started from the next music. If the determination in S85 is no, the process proceeds to S87.

  In S87, it is determined whether or not the type of editing performed by the user in the editing mode in S53 of FIG. 3 is file combination. If the determination is positive, the process proceeds to S88, and the file number = n + 1 is supported. Scan playback starts from the music to be played. If the file number = n and the file number = n + 1 are combined in the edit mode of S53, the file of file number = n + 1 is the next to the file edited in S53. And the scan playback starts from the next song. If the determination in S87 is no, the process proceeds to S89.

  In S89, it is determined whether or not the type of editing performed by the user in the editing mode in S53 of FIG. 3 is file division. If the determination is positive, the process proceeds to S90, and the file number = n + 2 is supported. Scan playback starts from the music to be played. The two files after the division have front and rear file numbers of n and n + 1, respectively, so the file with file number = n + 2 is the next file after the file edited in S53. Thus, the scan reproduction is started from the next file with respect to the file generated by the combination. If the determination in S89 is negative, the process returns to S50. If the determination in S89 is NO, it means that the user has pressed the edit key in S52 (FIG. 3) and has pressed the edit execution key in S60 (FIG. 4), but no editing has been performed.

  FIG. 7 shows a main part of a flowchart of the scan reproduction control method 100. 7 in the scan reproduction control method 100 corresponds to the flowchart division in FIG. 4 in the scan reproduction control method 40, and other flowchart divisions in the scan reproduction control method 100 are diagrams in the scan reproduction control method 40. 4 is the same as the flowchart classification of FIGS. In the scan reproduction control method 100, steps having the same processing contents as the steps of the scan reproduction control method 40 are designated by the same step numbers, description thereof will be omitted, and only differences from the scan reproduction control method 40 will be described.

  In the scan reproduction control method 100, S66 and S67 (FIG. 4) of the scan reproduction control method 40 are replaced with S101 and S102. In both the scan reproduction control methods 40 and 100, while the user is editing a file, the reproduction sound of the music of the file flows from the speaker 33. In the scan reproduction control method 40, the music is the music. In the scan reproduction control method 100, only the intro part of the music is repeated, while the reproduction is continued by returning to the beginning.

  In S101, it is determined whether or not the reproduction of the currently played music for a certain period of time (reproduction of the intro part) is completed. If the determination is positive, the process proceeds to S102, and if not, the process returns to S60. In S102, the process returns to the beginning of the audio file currently being reproduced, and the reproduction of the file is repeated.

  FIG. 8 shows a main part of the flowchart of the scan reproduction control method 110. The flowchart division of FIG. 8 in the scan reproduction control method 110 corresponds to the flowchart division of FIG. 6 in the scan reproduction control method 40, and the other flowchart divisions in the scan reproduction control method 110 are the flowcharts of FIGS. It is the same as the division. In the scan reproduction control method 110, steps having the same processing contents as the steps of the scan reproduction control method 40 are designated by the same step numbers, description thereof will be omitted, and only differences from the scan reproduction control method 40 will be described.

  In the scan reproduction control method 110, S86, S88, and S90 (FIG. 6) of the scan reproduction control method 40 are replaced with S111, S112, and S113. In S86, S88, and S90 of the scan reproduction control method 40, the scan reproduction is started from the music next to the music that has been edited, whereas in S111, S112, and S113, the scan reproduction is the file number. = N The music of the file, that is, the music that has been edited is started.

  In S111, the scan reproduction is restarted from the music of the file whose name has been changed. In S112, the scan reproduction is resumed from the combined file. In S113, the scan reproduction is restarted from the divided file. Since the file with the file number = n before the division has the file number = n and n + 1 after the division after the division, the scan reproduction is resumed from the front file portion in S113. In S113, scan reproduction = n + 1, that is, scan reproduction may be started from the back file.

  FIG. 9 shows a main part of the flowchart of the scan reproduction control method 120. The flowchart division of FIG. 9 in the scan reproduction control method 120 corresponds to the flowchart division of FIG. 6 in the scan reproduction control method 40, and the other flowchart divisions in the scan reproduction control method 120 are the flowcharts of FIGS. It is the same as the division. In the scan reproduction control method 120, steps having the same processing contents as the steps of the scan reproduction control method 40 are designated by the same step numbers, description thereof will be omitted, and only differences from the scan reproduction control method 40 will be described.

  In the scan reproduction control method 120, S81, S86, S88, and S90 (FIG. 6) of the scan reproduction control method 40 are replaced with S121, S122, S123, and S124. In S81, S86, S88, and S90 of the scan reproduction control method 40, the scan reproduction is started from the music next to the music that has been edited, whereas in S122, the music of the file with the file number = n, that is, editing. Scan playback is started from the music that has been completed, and in S121, S123, and S124, the scan playback is performed by scanning from the music of the file with the file number = n−1, that is, the music immediately before the music that has been edited. To start.

  In the scan reproduction control method 120, when the type of user editing in the editing mode is editing that affects the arrangement of files, such as file deletion, file combination, or file division, the editing is performed on the content to be edited. By playing the previous song, the user can accurately grasp the arrangement of contents changed by deletion, combination, and division, including surrounding contents.

  In S122 of the scan reproduction control method 120, the file number is set to n, but it is also possible to start the scan reproduction from a music piece two or more before the music piece that has been edited by setting the file number to a predetermined value less than n. Similarly, in S121, S123, and S124, the file number is set to n-1, but the file number is set to a predetermined value less than n-1, and scanning reproduction is started from two or more songs before editing. You can also.

  10 and 11 are explanatory diagrams specifically showing the relationship between the type of user editing and the scan start content after editing in the above-described scan reproduction control methods 40, 100, 110, and 120. FIG. In the example of FIGS. 10 and 11, it is assumed that the order of scan reproduction is music 1 → music 2 → music 3 → music 4 →... Further, it is assumed that the edit key (S52 in FIG. 3) is pressed.

  In each user editing type such as “file deletion” in FIG. 10 and FIG. 11, the music sequence following the “edit mode end instruction” is scanned and played back after the editing of each scan playback control method 40, 100, 110, 120 is completed. The order of the songs.

  FIG. 12 shows a modification of S54 in FIG. S541 to S543 are performed instead of S54. This modification is effective when applied to the scan reproduction control method 110 (FIG. 8) and 120 (FIG. 9). That is, in the scan reproduction control methods 110 and 12, when the scan reproduction is resumed after the editing is finished, the reproduction is started from the music to be edited or from the music having the reproduction order before the music to be edited. (S111 to S113 in FIG. 8 and S121, S123, and S124 in FIG. 9). In this case, although the user can confirm whether or not the music to be edited has been edited as desired, the music to be heard again appears in the scan reproduction after the restart. Since there are few cases in which a music piece that has been reproduced for the second time is subject to editing again by the user, it is more reasonable to proceed to the next music piece with a shorter reproduction time. S541 to S543 in FIG. 12 deal with this.

  In S541, it is determined whether or not the music currently being played is the first time. If the determination is positive, the process proceeds to S543, and if not, the process proceeds to S542. In S542, it is determined whether or not the playback time has reached a certain time (eg, 5 seconds) that is smaller than the default time (eg, 10 seconds). If the determination is positive, S70 (FIG. 5). If NO in step S50, the flow advances to step S50 (FIG. 3). In S543, it is determined whether or not the playback time has reached the default time. If the determination is positive, the process proceeds to S70, and if the determination is not, the process proceeds to S50.

  FIG. 13 and FIG. 14 are explanatory diagrams of changes in the reproduction time of each song in the scan reproduction control methods 40, 100, 110, 120 when the step of adjusting the music reproduction time in the scan reproduction period of FIG. 12 is applied. . In FIGS. 10 and 11 and FIGS. 13 and 14, the width of each piece of music indicates the reproduction time in the scan reproduction. The difference between FIGS. 13 and 14 with respect to FIGS. The point is that the playback time of some of the music pieces after the restart of playback is shorter than that of FIGS.

  When the scan playback is resumed after the editing mode related to the editing of the music 3 ends, depending on the type of editing in the scan playback control methods 110 and 120, the playback order of the music 3 that was the music to be edited is changed. The music before that (including the music 3 before that. The music 3 includes the music 3a and 3b obtained by dividing the music 3) is reproduced again. In FIGS. 13 and 14, the horizontal width of the music reproduced at the second time is almost half of the horizontal width after music 4. That is, the reproduction time before the music 3 after the scan reproduction is resumed is half the default time.

  FIG. 15 is a block diagram of the scan reproduction control device 130. An example of the scan reproduction control device 130 is the aforementioned system component 10 (FIG. 1). The content in the scan reproduction control apparatus 130 is not limited to audio, but may be video or other arbitrary reproducible content. The content is typically digital content such as MP3 or WMA. The scan reproduction control apparatus 130 may be an information processing apparatus such as a stationary or portable video apparatus, a mobile phone, or a PDA, in addition to a stationary or portable audio apparatus.

  The scan reproduction control device 130 includes an edit mode start instruction detection unit 131, an edit mode start unit 132, an edit mode end instruction detection unit 133, and a scan reproduction unit 134. The edit mode start instruction detecting unit 131 detects an edit mode start instruction from the user in a scan reproduction period in which a plurality of contents are partially reproduced in order. When the edit mode start means 132 detects the edit mode start instruction, the edit mode start means 132 starts the edit mode for the content being partially reproduced at that time.

  The edit mode end instruction detecting unit 133 detects an edit mode end instruction in the edit mode period. When the scan reproduction means 134 detects the edit mode end instruction, the scan reproduction unit 134 ends the edit mode, and starts scan reproduction from a predetermined content whose scan reproduction order is within a predetermined number before and after the content to be edited in the edit mode. .

  Specific processes corresponding to the functions of the edit mode start instruction detecting unit 131, the edit mode starting unit 132, and the edit mode end instruction detecting unit 133 are S52 (FIG. 3), S53 (FIG. 3), and S60 (FIG. 4), respectively. is there. Specific processing corresponding to the function of the scan reproduction means 134 is S81, S86, S88 (FIG. 6), S90, S111, S112, S113 (FIG. 8), S121, S122, S123, S124 (FIG. 9). It is.

  Typically, the content to be edited is continuously reproduced during the scan reproduction period, but the content to be edited may be intermittently reproduced or the reproduction may be completely stopped. In the scan reproduction, the part where each content is reproduced is not limited to the intro part, but may be an intermediate part, a tail part or a chorus part. The reproduction speed in the scan reproduction is not limited to 1 × speed, and can be made faster than that. The content editing is, for example, deleting, renaming, combining, or dividing the content file.

  “Within the predetermined number before and after” in the “predetermined content whose scan reproduction order is within the predetermined number before and after the content to be edited in the editing mode” is preferably within the first or second before and after, It may be within a higher number.

  In the scan playback control method 40 (FIG. 6), 100, the predetermined content for which the scan playback means 134 starts scan playback after the detection of the edit mode end instruction scans and reproduces the content that has been edited by the edit mode end instruction. In the scan reproduction control method 110 (FIG. 8), the content is the content that has been edited in response to the editing mode end instruction, and in the scan reproduction control method 120 (FIG. 9). The content that has been edited in response to the editing mode end instruction is the content in the scan reproduction order one before that.

  The scan reproduction control device 130 resumes the scan reproduction as soon as the user exits the edit mode. In the resumed scan reproduction, the scan reproduction is not started from the first content in the scan reproduction order, but is reproduced to the content that has been edited. Since the content is started from nearby content in order, the user can efficiently search for the next content to be edited.

  Preferably, the scan reproduction unit 134 determines the predetermined content, that is, the reproduction start content when the scan reproduction is resumed, based on the type of editing of the edited content. Specific examples are S80 → S81, S85 → S86, S87 → S88, S89 → S90 in FIG. 6, S80 → S81, S85 → S111 in FIG. 8, S87 → S112, S98 → S113, and S80 → S121 in FIG. S85 → S122, S87 → S123, S89 → S124.

  The predetermined content determined by the scan reproduction unit 134 based on the type of editing in this manner is based on the content to be edited in the edit mode as the reference content, and the scan reproduction order is after the reference content, the reference content itself, The scan reproduction order may be before the reference content (eg, FIGS. 10 and 11).

  Preferably, the scan playback unit 134 sets the predetermined content to the content whose playback order is before the content to be edited in the edit mode and resumes the scan playback from the predetermined content. The scan playback time of each content is set shorter than the scan playback time of each content whose playback order is after the content to be edited. A specific example is S541 to S542 in FIG. 12, and in FIGS. 13 and 14, when scanning reproduction is resumed after the editing mode ends, the reproduction times of the songs 2, 3, 3a, 3b before the song 3 to be edited are I explained that it was half the default time.

  Preferably, the scan reproduction control device 130 includes a file data update unit 137. The file data updating unit 137 updates the file data of the content in the recording medium 138 based on the user editing of the content at the end of the editing mode for each content. Correspondingly, the scan reproduction means 134 updates the content reproduction order in the scan reproduction based on the updated file arrangement in the recording medium 138 every time the file data in the recording medium 138 is updated. Specific examples are S78 and S79 in the intro reproduction control method 40.

  Some contents editing affects the total number of contents to be scanned and reproduced and the order of reproduction such as division, combination or deletion of files. The file data updating unit 137 updates the file data in the recording medium 138 every time the editing mode ends and updates the playback order of the content in the scan playback based on the updated file layout in the recording medium 138. First, it is possible to appropriately control the start content in the scan reproduction after the content editing is completed and the subsequent reproduction order.

  FIG. 16 is a flowchart of the scan reproduction control method 150. The scan reproduction control method 150 is applied to the scan reproduction control device 130. In S151, it is determined whether or not it is a scan reproduction period in which a plurality of contents are partially reproduced in order. If the determination is positive, the process proceeds to S152, and if not, the scan reproduction control method 150 is terminated. In S152, it is determined whether or not an edit mode start instruction from the user has been detected, and the process proceeds to S153 as soon as the determination becomes positive.

  In S153, the editing mode for the content being partially reproduced at that time is started. In S154, it is determined whether or not an editing mode end instruction is detected in the editing mode period, and the process proceeds to S155 as soon as the determination becomes positive. In S155, the edit mode ends. In S156, the scan reproduction is started from the predetermined content whose scan reproduction order is within a predetermined number before and after the content to be edited in the edit mode.

  The processing of S151 and S152 corresponds to the function of the edit mode start instruction detecting means 131 of the scan reproduction control device 130. The processes of S153 and S154 correspond to the functions of the edit mode start unit 132 and the edit mode end instruction detection unit 133, respectively. The processing of S155 and S156 corresponds to the function of the scan reproduction means 134. Therefore, the specific modes described for the functions of the respective units in the scan reproduction control apparatus 130 can also be applied as specific modes for the processing of each step corresponding to them in the scan reproduction control method 150.

  In the scan reproduction control method 150, a step of executing a process corresponding to the function of the file data update unit 137 of the scan reproduction control apparatus 130 can be added. The additional step is inserted between S155 and S156. In response to this, in step S156, the content reproduction order in the scan reproduction is updated based on the updated file arrangement in the recording medium 138 every time the file data in the recording medium 138 is updated.
