  In a conventional audio apparatus, when a desired music piece is found by reproduction such as normal reproduction or intro reproduction, and the edit mode for the music is entered, reproduction of the music ends. Therefore, the user cannot listen to the playback sound of the music while editing the music, and cannot check the music to be edited during editing, so the user may make an incorrect edit. It is easy to get up. In addition, the user's desire to listen to the music to be edited is not satisfied.

  In the conventional audio device, not only the edit mode period by the edit mode instruction from normal playback or intro playback, but also the normal editing in which the user directly specifies the audio file by name, number, etc. and edits the audio file. Even during the mode period, the playback sound of the music to be edited is not played. Accordingly, the same problem as in the edit mode period by the edit mode instruction from the intro playback occurs even in the normal edit mode period.

  An object of the present invention is to provide a content editing apparatus, method, and program capable of confirming a music piece in the editing mode.

  According to the present invention, the content to be edited is reproduced during the edit mode period.

The content editing apparatus of the present invention includes the following means.
Edit mode period detection means for detecting an edit mode period from when an instruction to start editing for content is detected until an operation input for confirming the edit content is input;
Editing target content detection means for detecting the current editing target content; and
It has a function of executing a scan playback that sequentially plays back a partial playback range that is a part of content for a plurality of contents, and scans when the edit mode period detecting means detects the edit mode period during scan playback. Reproduction means for reproducing the current editing target content without reproduction.

The content editing method of the present invention includes the following steps.
An edit mode period detection step for detecting an edit mode period from when an instruction to start editing the content is detected until an operation input for confirming the edit content is input;
An editing target content detection step for detecting the current editing target content; and
It has a function of executing scan playback for sequentially playing back a partial playback range that is a part of content for a plurality of contents, and scans when the edit mode period is detected in the edit mode period detection step during scan playback. A playback step of playing back the current content to be edited without playback.

  The program of the present invention causes a computer to function as each unit of the above-described content editing apparatus of the present invention.

  According to the present invention, since the content to be edited is played back during the edit mode period, the user cannot check the music to be edited, so that the situation where the user makes an incorrect edit is prevented. Can do. Further, the user can edit the content while enjoying the reproduction of the editing target content.

  The best mode and the like will be described below with reference to the drawings. Note that “intro play” and “intro play” are distinguished from each other. “Intro play” means playing the intro part of one piece of music. “Intro play” means playing the intro part of each piece of music in a predetermined order. Shall mean.

  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 intro playback and editing with respect to a connected, mounted, or built-in recording medium. Here, the music file to be edited will be described with respect to the music file searched by intro play, but the specification of the music file is not limited to this, and the music file may be searched using the display unit 15 of the content editing apparatus. .

  2 to 6 show the entire flowchart of the intro regeneration control method 40 in a divided manner. The intro regeneration control method 40 is applied to the system component 10 of FIG. Recording media to be intro played in the system component 10 are not only the memory card 25, the USB memory 27 or the built-in hard disk device, but also can be built in or detachable in 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 intro playback target recording medium are not subject to the intro playback, and are determined based on the user designation. 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 intro playback control method 40, when the playback sound of the desired music flows from the speaker 33, the user presses the confirmation key (positive in S50 of FIG. 3), and the music is played following the intro playback of the music. Can be played to the end, or the editing key can be pressed (the correct in S52 in FIG. 3), and the music can be edited in a predetermined manner (deletion or name change of the music file). . In the intro playback control method 40, the playback sound of the music continues to be played 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).

  In the flowchart section of FIG. 2, in S41, it is determined whether or not the user has input (operated) the intro play 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 on which intro reproduction is performed). 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 intro playback, the user can select which intro playback media is to be used this time.

  In S43, the data of the file arrangement that determines the reproduction order of the intro reproduction is read from the recording medium, and when the reading is completed, the process proceeds to S44. The playback order of the music in the intro playback is, for example, the order of the addresses of the files. When the folders on the recording medium have a tree structure, for example, the folders can be arranged with priority on the width and determined based on the arrangement order. Instead of width priority, the playback order can be determined based on depth priority.

  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 wishes to reproduce all of the intro playback currently being performed. In S52, with respect to the music that plays sound when the enter key is operated, the reproduction of the music is continued following the reproduction of the intro.

  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 that is currently being played from the speaker 33 has reached a certain time. If the determination is positive, the intro playback for the music is ended. The process proceeds to S70 (FIG. 5), and if no, the process returns to S50 and the intro reproduction 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 intro playback is stopped in order to edit the content that is being played back.

  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, the user depresses the edit cancel key to cancel the editing of the corresponding music or return to the original intro playback 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 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 intro 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 for which intro playback has been completed in S65 (FIG. 4) is the last file in the intro playback order. If the determination is positive, intro playback is performed. Stop. On the other hand, if the determination in S70 is negative, the process proceeds to S72, where intro playback of the next audio file is started.

  In the flowchart section of FIG. 6, in S78, data for determining the playback order of the music in the intro 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 intro 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 involve changes in the total number of intro-played music and the file number, and if not updated, S81 , S86, S88, S90, the starting music becomes inappropriate when the starting music is determined, and this is prevented. In the intro playback 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, by re-reading the data for determining the playback order of the intro playback from the recording medium, in the intro playback after the editing is completed, the playback start of the music and the subsequent playback order become appropriate.

  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. Intro playback starts from the music to be played. The file number (= n) assigned to the file by deleting the file becomes the next file with respect to the file, and the intro 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. Intro play starts from the corresponding song. In this case, the file with the file number = n + 1 becomes the next file with respect to the file edited in S53, and the intro 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. Intro 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 intro 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. Intro 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. In this way, intro 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 the flowchart of the intro reproduction control method 100. The flowchart portion of FIG. 7 in the intro playback control method 100 corresponds to the flowchart portion of FIG. 4 in the intro playback control method 40, and the other flowchart portions in the intro playback control method 100 are diagrams in the intro playback control method 40. 4 is the same as the flowchart portion of FIGS. In the intro playback control method 100, steps having the same processing contents as the steps of the intro playback control method 40 are designated by the same step numbers, description thereof will be omitted, and only differences from the intro playback control method 40 will be described.

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

  In S101, it is determined whether or not the reproduction of the currently played music for a certain period of time (intro reproduction) 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 intro reproduction control method 110. The flowchart portion of FIG. 8 in the intro playback control method 110 corresponds to the flowchart portion of FIG. 6 in the intro playback control method 40, and the other flowchart portions in the intro playback control method 110 are the flowcharts of FIGS. Is identical to the part. In the intro playback control method 110, steps having the same processing contents as the steps of the intro playback control method 40 are designated by the same step numbers, description thereof will be omitted, and only differences from the intro playback control method 40 will be described.

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

  In S111, the intro play is resumed from the music of the file whose name has been changed. In S112, the intro playback is resumed from the combined file. In S113, the intro playback is resumed 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, the intro playback is resumed from the front file portion in S113. In S113, intro playback = n + 1, that is, intro playback may be started from the back file.

  FIG. 9 is a block diagram of the content editing apparatus 130. An example of the content editing apparatus 130 is the above-described system component 10 (FIG. 1). The content in the content editing apparatus 130 is not limited to audio, and may be video or other arbitrary reproducible content. The content is typically digital content such as MP3 or WMA. The content editing 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 content editing apparatus 130 includes an editing mode period detection unit 131, an editing target content detection unit 132, and an editing target content reproduction unit 133. The edit mode period detection unit 131 detects an edit mode period for the content. The editing target content detection unit 132 detects the current editing target content. The editing target content playback unit 133 plays back the editing target content during the editing mode period.

  Typically, the start of the edit mode period is when an edit mode start instruction from the user is detected during the period in which the content is being played back, and the content to be edited is played back when the edit mode start instruction is detected from the user. Content. The period during which the content is reproduced includes not only a scan reproduction period in which a plurality of contents are partially reproduced in order, but also a normal reproduction period that is not scan reproduction.

  Note that scan reproduction is not limited to intro reproduction. In the scan reproduction, it is assumed that the portion where each content is reproduced may be an intermediate portion other than the intro portion of each content, the end portion or the chorus portion.

  The edit mode period in the content editing apparatus 130 may be started irrespective of the scan reproduction. That is, for example, the user can enter the edit mode for the content by designating the file number or selecting from the list without searching for the content desired to be edited from the scan reproduction.

  The specific processing of the intro playback control method 40 corresponding to the function of the edit mode period detection means 131 in the case of the edit mode transition from scan playback is S52 (FIG. 3), S60, and S64 (FIG. 4). The specific processing corresponding to the function of the editing target content detection unit 132 is S52 (FIG. 3), S60, and S64 (FIG. 4). S52 corresponds to the start of the edit mode period, and S60 and S64 correspond to the end of the edit mode period. Specific processing corresponding to the function of the editing target content reproduction means 133 is S66, S67 (FIG. 4) and S101, S102 (FIG. 7).

  Preferably, the editing target content reproduction unit 133 repeatedly reproduces the editing target content until the end of the editing mode period. The specific processing corresponding to the function of the editing target content reproduction means 133 is S66. This is S67 or S101 and S102 in FIG.

  Typically, the repeated playback range for the editing target content during the editing mode period by the editing target content playback unit 133 is the partial playback range for the target content or the entire range for the editing target content. The partial playback range for the target content matches, for example, the partial playback range for the editing target content in scan playback. The specific processing corresponding to the former function is S101 and S102 in FIG. 7, and the specific processing corresponding to the latter function is S66. S67.

  The reproduction speed in scan reproduction is not limited to 1 × speed, and it can be made faster or slower. The content editing is, for example, deleting, renaming, combining, or dividing the content file.

  In the content editing apparatus 130, the user edits the content to be edited while the content to be edited is being reproduced. Therefore, the user may forget what is the content to be edited or make a mistake. As a result, efficient and appropriate editing can be performed. In addition, since the content to be edited is being played back, editing can be performed while having fun.

  FIG. 10 is a flowchart of the content editing method 150. The content editing method 150 is applied to the content editing device 130. In S151, an edit mode period for the content is detected. Specifically, it is determined whether or not the current time is the editing mode period for the content. If the determination is positive, the process proceeds to S152, and if not, the content editing method 150 is terminated.

  In S152, the current editing target content is detected. In S153, the content to be edited is reproduced during the edit mode period.

  The processes of S151, S152, and S153 correspond to the functions of the edit mode period detection unit 131, the edit target content detection unit 132, and the edit target content reproduction unit 133 of the content editing apparatus 130, respectively. Therefore, the specific modes describing the functions of the editing mode period detecting unit 131, the editing target content detecting unit 132, and the editing target content reproducing unit 133 in the content editing apparatus 130 are the processes of S151, S152, and S153 in the content editing method 150. The present invention can also be applied as a specific embodiment.

  The program to which the present invention is applied causes a computer to function as each unit of the content editing apparatus 130. Another program to which the present invention is applied causes a computer to execute each step of the content editing method 150.

  Although the present invention has been described with respect to the best mode, the present invention is not limited to this, and each constituent element in the best mode can be modified and embodied without departing from the gist of the invention. Various inventions can be formed by a convenient combination of a plurality of constituent elements disclosed in the best mode.
