Description

  The present invention relates to a content playback apparatus that plays back music files and the like in a storage device and a file management method used therefor, and more particularly to a content playback apparatus that uses a file name for managing playback files and a file management method used therefor.

  In audio editing software installed in a PC (personal computer), when a music file for a CD-DA (Compact Disc Digital Audio) music is generated in a storage device such as a PC HD (hard disk) by ripping, for example, , "Half-width space-Half-width space ("-")" is used as a delimiter to divide the file name into multiple categories, and "" Track number "-" Artist name "-" Music name "-" Album name " The file name in which music information is entered in each category is given to each music file. Then, when the album is reproduced later, the information of each division of the file name is used as the reproduction order and display information.

  The artist name and the song name are obtained from CD text or the Internet CDDB (CD database) server, etc. The CD-DA to be ripped this time does not have the CD text, and the CDDB If the corresponding music information does not exist or the CDDB cannot be used, the file name correspondence classification is null, and the user will manually input the music information later.

  In Patent Document 1, an MP3 (MPEG Audio Layer-3) file generated by ripping is stored on a CD-R in one layer (FIG. 4 of Patent Document 1) or multiple layers (FIG. 6 of Patent Document 1). The display example (FIG. 5, FIG. 7 and FIG. 8 of Patent Document 1) of the music list on the display is disclosed. In addition, if there are too many songs and the list of all songs cannot be displayed on one screen, or if some songs are too long and the name of the song protrudes from the screen, scroll and cursor operations. (Paragraphs 0034 and 0036 of Patent Document 1) also discloses that the non-display portion is appropriately moved and displayed in the screen.

  Patent Document 2 discloses recording a song name and an artist name using ID3-TAG information that can be stored in the header of an MP3 file (paragraph 0003 of Patent Document 2). At the time of MP3 file playback, the presence / absence of text data in the ID3-TAG information in the MP3 file to be played back is determined (S62 in FIG. 6 of Patent Document 2). If there is text data, the text data is displayed ( If not, the file name is displayed instead of the text data (S64 of FIG. 6 of Patent Document 2).

  On the other hand, in Windows XP (registered trademark) or the like, for a file stored in a storage device, a short file name (the number of characters of the main body is 8 bytes or less and the number of extension characters is 3 bytes or less) or a long file name (= file name other than the short file name) ).

JP 2002-343067 A JP-A-2005-251287

  In some cases, a user manually inputs a music file that includes information on the serial number and music name in the file name, and the audio device itself automatically changes the file name. In the conventional audio device, there is no restriction on the change of the file name. Therefore, for example, if the serial number or separator in the file name is changed, the songs in the album cannot be played in the correct order when the album is played after the file name is changed.

  Japanese Patent Application Laid-Open No. 2004-228561 describes an improvement plan for displaying a list of music file names and the like of audio files in a storage device after ripping on a screen. However, there is no problem regarding a reproduction file management problem associated with file name rewriting by a user. Not mentioned. In Patent Document 2, although the display information source of MP3 file is selectively used as ID3-TAG information or a text table depending on whether or not text data is included as ID3-TAG information (see FIG. 6 of Patent Document 2). S62 to S64), there is no mention of how to deal with the problem when the user rewrites the file name.

  An object of the present invention is to guarantee a change of a file name by a user or the like in a content reproduction apparatus that uses a file name for managing a file in a storage device and a file management method used therefor without causing any trouble in the management. It is.

  The present invention rips a plurality of contents composed of a plurality of files or folders recorded on a first recording medium and records them on a second recording medium, and each of the contents ripped by the ripping means. When recording on the second recording medium, the ripping is performed based on a first assigning unit that assigns a first name having a first number of characters to each content, and a name editing operation by a user. A second assigning means for assigning a second name having a second number of characters longer than the first number of characters to each of the contents ripped by the means; and displaying the name of the content when the content is played back And the first giving means uses the ripping hand as the first name. A name consisting of continuous numerical values or letters is assigned in the order of ripping by the first name, and the first name given by the first giving means is restricted from being renamed, and the name of the content is displayed on the display. When displaying, the second name is displayed if the second name is assigned to the content, and the second name is displayed if the second name is not assigned to the content. A content playback apparatus that displays a first name.

  In the content reproduction apparatus, when the first name or the second name is displayed on the display, the main part of the first name or the second name excluding an extension is displayed. preferable.

  Further, the present invention provides a ripping step of ripping a plurality of contents composed of a plurality of files or folders recorded on the first recording medium and recording them on the second recording medium, and each of the ripped in the ripping step When recording the content on the second recording medium, a first giving step for giving a first name consisting of a first number of characters to each content, and after the first giving step, A second assigning step of assigning a second name having a second number of characters longer than the first number of characters to each of the contents ripped in the ripping step based on a name editing operation by the user And a display step for displaying the name of the content on a display when the content is played back. In the first assigning step, as the first name, a name consisting of a continuous numerical value or a character in the order of ripping in the ripping step is given, and the first name given in the first assigning step The name change is limited, and when the display step displays the name of the content on the display, the second name is given to the content if the second name is given to the content. A content management method used for a content reproduction apparatus, wherein a name is displayed and the first name is displayed when the second name is not assigned to the content.

  In the file management method used in the content reproduction apparatus, the display step includes the step of displaying the first name or the second name excluding an extension when displaying the first name or the second name on the display. It is preferable to display the body part of the name.

  According to the present invention, different types of first and second file names are assigned to one reproduction file, and the first and second file names are restricted and allowed to be changed, respectively. As a result, it is possible to ensure the change of the file name by the user or the like while avoiding the trouble to the predetermined management.

It is a figure which shows the various apparatuses which mount the file name management software of AV file, and cooperation relation. It is a figure which shows the change process of a file name when the name edit work by a user is implemented after ripping about the music of CD-DA without CD text. It is a figure which shows the change process of the file name at the time of implementing ripping about CD-DA with CD text. It is a figure which shows the work screen of the file name change by a user as an example. It is a flowchart of a ripping process. It is a flowchart of a file name display process. It is a block diagram of a file management apparatus. It is a flowchart of the reproduction | regeneration file recording routine in a file management method. 5 is a flowchart of a file name change request routine in a file management method 70.

  FIG. 1 shows various apparatuses that implement file name management software for AV (Audio & Visual) files and their linkages. The AV file includes an audio file such as MP3 standard and WAV standard, an image file such as JPEG standard, and a moving image file such as MPEG standard. Hereinafter, for simplicity of explanation, the AV file is assumed to be a music file which is a kind of audio file.

  The digital audio player 10, the stationary audio device 11, and the PC 12 as playback devices incorporate a storage device such as a hard disk or a flash memory, and store music files in the storage device. The digital audio player 10, the stationary audio device 11 and the PC 12 appropriately read the music file in the storage device, and can output the music playback sound from its own speaker or earphone, and the music in the storage device. Editing such as changing the file name on the file can be performed as appropriate by the device itself.

  The stationary audio device 11 and the PC 12 copy or move the music file stored in the hard disk device of the device to a removable flash memory such as an SD memory card, and attach the removable flash memory to the digital audio player 10. Thus, the music in the detachable flash memory can be reproduced by the digital audio player 10. Further, the music file in the detachable flash memory can be edited by the stationary audio apparatus 11 and the PC 12 such as a file name.

  The digital audio player 10 and the stationary audio device 11 are connected to each other via a cable 15. In the connection state with the cable 15, the music file in the storage device of the stationary audio device 11 is encrypted and then stored in the storage device of the digital audio player 10, or the music file in the storage device of the digital audio player 10 is stored by the user. Can be edited in the stationary audio device 11, and the user can output the music playback sound of the music file in the storage device of the digital audio player 10 from the speaker of the stationary audio device 11.

  Similarly, the digital audio player 10 and the PC 12 are connected to each other via a cable 16 such as a USB cable. When the cable 16 is connected, the music file in the storage device of the PC 12 is encrypted and then stored in the storage device of the digital audio player 10, or the user edits the music file in the storage device of the digital audio player 10 on the PC 12. It is possible to do.

  Similarly, the stationary audio apparatus 11 and the PC 12 are connected to each other via a cable 17 such as a USB cable. In the connection state by the cable 17, the music file can be transferred between the stationary audio device 11 and the PC 12, or the user can edit the music file in the storage device of the stationary audio device 11 on the PC 12. It is.

  FIG. 2 shows a process of changing a file name when a CD-DA music without CD text is ripped and a name editing operation is performed by the user thereafter. The ripping from the CD-DA may be performed in any of the digital audio player 10, the stationary audio device 11, and the PC 12, but hereinafter, for convenience of explanation, the digital audio player 10 is selected as a representative. The case of the digital audio player 10 will be described. In the digital audio player 10, files in the storage device are managed in a tree structure.

  As shown in FIG. 2A, there is one folder with the name “ABCD” in the storage device before ripping, and ABC. mp3, efg. wma, HIJ. Assume that three files of doc are stored. Regarding the extension of the file name, mp3 indicates that the file is an audio MP3 standard file, wma indicates that the file is an audio wma (Windows Media Audio) standard file, and doc is a word processor software of Microsoft Corporation. It is a Word file.

  With the ripping of the CD-DA music, the folder with the folder name “Album001” is located under the folder with the folder name “Special” in the storage device of the digital audio player 10 as shown in FIG. Created as a hierarchy. The folder name “Album001” is a folder name that the digital audio player 10 gives as a default folder name when ripping from a CD-DA. If the current CD-DA has CD text, the folder name “Album001” is typical. Is the album name of the CD-DA album instead of “Album001”. Note that the folder with the folder name “Special” is set as a special folder in the storage device in the digital audio player 10, and the digital audio player 10 issues an edit request and playback request for the music file from the user Then, first, the “Special” folder is accessed, and the corresponding music file is searched from this folder.

  In this example, each piece of music data in the folder is converted into a wma standard music file and stored in the folder “Album001”. Each music file is given a short file name with a file name (TR001.wma, TR002.wma,...) Including the track order in the CD-DA as a numerical value. The short file name is, for example, a file name having a main body character length of 8 bytes or less and an extension character number of 3 bytes or less in accordance with Windows (registered trademark) of the personal computer OS. Or a file name having an extension character number of 4 bytes or more. However, in the digital audio player 10, the short file name and the long file name are assigned independently from each other, that is, in the name standard adopted, the text up to the first 8 digits of the long file name becomes the short file name. The standard has no dependency. Further, in the name standard, a short file name is essential, whereas a long file name is null, that is, it may not be necessary.

  In the digital audio player 10, the numerical value included in the short file name is used for management of the reproduction order as management data for the serial number. Further, at the stage of FIG. 2B, the long file name of each music file is null (empty). 2 (b) and 2 (c) and FIGS. 3 (b) and 3 (c) to be described later, the short file name and the long file name are shown on the left side and the right side of “:” for each wma music file. .

  Ripping based on CD-DA without CD text ends in the file name state of FIG. When the digital audio player 10 receives a user instruction for all-track playback or continuous playback for the folder “Album001”, the digital audio player 10 detects a numerical value related to the serial number included in the short file name of the music file in the folder, and each music file in the sequential order. Will play the songs. During the playback of each song file, text information such as the song name of the playback song is displayed on the display of the digital audio player 10 based on the long file name. The long file name is shown in FIG. In this state, the digital audio player 10 displays a short file name on the display instead of the information (described later in S44 of FIG. 6).

  After ripping, the user edits the file name himself / herself in order to display appropriate music information on the display during reproduction of the music of each music file. In addition, by connecting the digital audio player 10 to the CDDB server via the Internet and downloading music information from the CDDB, it is possible to automatically input instead of the user input. Editing of file names by the user is prohibited for short file names, and long file names are targets. FIG. 2C shows a state in which the user has changed the file names of the music files 1 to 3 in the folder “Album001”.

  In FIG. 2 (c), the music files with serial numbers 1 to 3 are left unchanged in their short file names, while their long file names are “kakikukeko.wma”, “sasiseseo.wma”, respectively. Changed to “tattituto.wma”. As a result, even when the long file name is changed, if the user instruction for all-track playback or continuous playback is received for the folder “Album001”, the sequential number of each file is calculated from the numerical value included in the short file name of the music files in the folder. Judgment can be made and the music of each music file can be reproduced without any trouble in the order of the number. In addition, when playing the music numbers 1 to 3, the display of the digital audio player 10 shows the main part of the long file name (= long file name part excluding the extension part) "titletoto" "is displayed as reproduced music information.

  The long file name “kakikuko” etc. of each music file input by the user is typically input in a predetermined order while separating the artist name, music name and album name with a predetermined separator for each file. It has become. In order to streamline the input work, the delimiter may be automatically input when the user presses the tab key once. When playing back a music file, the digital audio player 10 extracts music information such as a music name and artist name from each section of the long file name of the file, and displays it on the display.

  FIG. 3 shows a process for changing a file name when ripping is performed on a CD-DA with CD text. 3A and 3B are the same as FIGS. 2A and 2B, respectively. In the case of ripping CD-DA without CD text, ripping is completed with the file name state shown in FIG. On the other hand, in ripping for CD-DA with CD text, the processing is further continued after FIG. 3B, and the digital audio player 10 automatically sets the long file name of each music file to CD. Editing based on the text leads to the file name state of FIG.

  In FIG. 3C, the long file names of the music files are “kakikukeko.wma”, “sasiseseo.wma”, “tattituto.wma”. “Naninuneno.wma”, “hahihuheho.wma”. Since the long file name is automatically input by the digital audio player 10 based on the CD text of the CD-DA, the time-consuming manual input in FIG. 2C is omitted.

  FIG. 4 exemplifies a work screen for changing the file name by the user. In the file name display window 24 on the display 23 of the digital audio player 10, the name of the music file called by the user as the file name change target is displayed. In FIG. 4, for example, the name of a music file whose short file name is “TR001.wma” is called.

  If a long file name is already assigned to the called music file, the long file name is displayed in the file name display window 24. FIG. 4A shows a file name display window 24 in the case where a long file name “kakakaka.wma” has already been assigned to a music file.

  When the long file name is not given to the called music file, that is, when the long file name is null, the short file name of the music file is displayed in the file name display window 24. FIG. 4B shows a state where the short file name “TR001.wma” is displayed in the file name display window 24 when the long file name of the music file is null. In the file name display window 24, the extension can be omitted from the display without displaying all of the short file name and the long file name.

  The user uses the file name display window 24 to edit the displayed file name. FIG. 4C shows the file name display window 24 when the input of up to “kakeukuke” is completed as the file name. When a long file name is displayed in the file name display window 24 and the user performs an editing operation, the file name edited by the user is registered as the long file name of the music file. When a short file name is displayed in the file name display window 24 and the user performs an editing operation, the file name edited by the user is registered as the long file name of the music file. The short file name retains the same name as before editing even after the long file name has been edited.

  Further, in the typical digital audio player 10, when the extension “wma” is also displayed in the file name display window 24, it is normal to prohibit the user from changing or newly inputting the extension. . As for the extension, the digital audio player 10 gives a predetermined extension.

  As the user uses the music file in the digital audio player 10, the user may delete unnecessary music files from the storage device. In the short file name explained in FIG. 2 and FIG. 3, the name portion related to the serial number is a three-digit number such as 001, 002,. I can't. The serial number of the deleted music file becomes a missing number, and when such a number increases, the number of music files in the storage device is within the maximum number of 999, and the number of music files in the back is changed. You will not be able to assign a serial number.

  In order to cope with this, in the digital audio player 10, when the last serial number is near the maximum value, the serial number is appropriately renumbered (also referred to as “refresh”) based on a user instruction or automatically. It is like that. Of course, during the renumbering process, the restriction on changing the short file name is released. Then, with respect to the files remaining in the storage device, the sequential number portion of the short file name of each music file is changed so that the sequential number sequence is maintained and the sequential number is continuous. As a result, the missing serial number is eliminated.

  A plurality of short file names and long file names can be assigned to folders. For example, the folder's short file name includes a numerical value related to the serial number, the folder's long file name includes an album name or artist name, the long file name is allowed to be changed by the user, and the short file name is Take measures to prohibit user changes. Thereby, when a plurality of folders are reproduced at a time, the reproduction order of the folders can be maintained.

  FIG. 5 is a flowchart of the ripping process. The ripping process corresponds to the file name changing process shown in FIGS. In S35, a short file name including a numerical value related to the serial number is assigned to each music file. In S35, Tr01, Tr02,... Indicate the track number of each musical piece on the CD-DA, and TR001, TR002,.

  In S36, it is determined whether or not the CD text copy function in the digital audio player 10 is ON. The user can select ON / OFF of the CD text copy function. If the determination in S36 is positive, the process proceeds to S37, and if not, the ripping process is terminated.

  In S37, it is determined whether or not the current CD-DA has CD text. If the CD-DA is positive, the process proceeds to S38, and if not, the ripping process is terminated. In S38, a long file name including the corresponding CD text is assigned to each music file.

  FIG. 6 is a flowchart of the file name display process. The file name display process is started, for example, when the music file is started to be reproduced in the digital audio player 10 or when the user starts editing the file name.

  In S42, it is determined whether or not the music for which the file name display process is to be performed has a long file name. If the determination result is positive, the process proceeds to S43, and if not, the process proceeds to S44. In S43, the long file name is displayed on the display of the digital audio player 10. In S44, the short file name is displayed on the display of the digital audio player 10.

  FIG. 7 is a block diagram of the file management apparatus 50. The digital audio player 10, the stationary audio device 11, and the PC 12 in FIG. 1 are specific examples of the file management device 50. The processing of the file management device 50 includes the processing described with reference to FIGS.

  The file management device 50 includes a reproduction file recording unit 51 and a file name assigning unit 52. The reproduction file recording means 51 records a reproduction file 58 for reproducing the content information in the storage device 59. The file name assigning means 52 assigns the first and second file names to each reproduction file 58 recorded by the reproduction file recording means 51.

  The first file name is a name including a continuous description, and the change is restricted. The second file name is a name that includes a description associated with the attribute of the playback file and is allowed to be changed.

  The reproduction file 58 includes at least a music file, an image file, and a moving image file. For the second file name, the description associated with the attribute of the playback file is, for example, a song name, album name, or artist name included in the CD text. The user can use the second file name when he / she wants to attach his own memo to each playback file.

  The first and second file names may be the short file name and the long file name described in FIG. That is, the first and second file names can be, for example, names having a number of characters less than a predetermined value and a number of bytes greater than, respectively. It should be noted that the first and second file names can be mutually independent names, and the second file name may initially be null.

  The continuous description included in the name of the first file name includes, for example, continuous numerical values (example: 001, 002, 003,...), Continuous characters (example 1: a, b, c,.・ ・ Example 2: Ai, i, u,..., And a mixture thereof (example: a01, a02,..., A99, b01, b02,... B99, c01,...) is there.

  Typically, the continuous description in the first file name is a description related to a predetermined processing order for a plurality of playback files. The predetermined processing order is, for example, the default ripping order when the user does not designate the ripping order when ripping from the CD-DA, that is, the track number order in the CD-DA, or the user designates the ripping order. And the recording order of the playback file 58 to the storage device 59 (this recording order is usually the same as the ripping order).

  The first file name is used as sort management data for a plurality of playback files 58, for example. As the sort management data, there is, for example, a serial number that defines the playback order of music.

  The second file name is, for example, text data of content information of the reproduction file 58. Specific examples of such text data include a song name, artist name, and album name included in the CD text. Further, the content memo written by the user may be the whole or part of the main body part (= excluding the extension) of the second file name.

  The user may delete unnecessary playback files as appropriate. As a result, at the beginning of ripping, the first file name is discontinuous partially missing although the description is continuous. In addition, due to restrictions on the number of characters for the first file name, there is a maximum value limit for continuous description, and the first file name assigned to the playback file 58 may be exhausted.

  In order to cope with this, it is desirable to reassign the first file name to eliminate the discontinuity when the lack of continuous description of the first file name becomes appropriately large. Preferably, the file name assigning unit 52 removes the restriction on the change of the first file name for the discontinuity described in the first file name caused by the partial deletion of the reproduction file 58. The first file name of the non-deleted playback file is returned to the continuous description. Note that the serial number or the like may be set independently for each folder in the storage device 59, or a continuous serial number may be set for the entire storage device 59.

  The file name assigning means 52 may be applied as means for assigning a folder name to a folder including at least one reproduction file 58 instead of assigning a file name to the reproduction file 58.

  The file management method 70 will be described based on the flowcharts of FIGS. FIG. 8 is a flowchart of a reproduction file recording routine in the file management method 70, and FIG. 9 is a flowchart of a file name change request routine in the file management method 70. The reproduction file routine (FIG. 8) is activated when a new reproduction file 58 is recorded in the storage device 59, for example, at the time of ripping.

  The file name change request routine (FIG. 9) includes, for example, when CD text is included in the file name when ripping from CD-DA with CD text, or when the user renames the file name after ripping. To start. The process of FIG. 2 (b) → FIG. 2 (c) is an example of the latter, and FIG. 3 (b) → FIG. 3 (c) is an example of the former.

  In the reproduction file recording routine (FIG. 8), a reproduction file 58 for reproducing the content information is recorded in the storage device 59 in S71. In S72, a first file name including a continuous description and a second file name including a description associated with the attribute of the reproduction file are assigned to each reproduction file 58 recorded in the storage device 59. .

  The file name change request routine (FIG. 9) limits the change to the file name change request if it is the first file name, and accepts the file name change request if it is the second file name. To do.

  That is, in S76, it is determined whether or not the current file name change request is for the first file name. If the determination is positive, the process proceeds to S77, and if not, the process proceeds to S78. In S77, the change of the first file name is restricted. The restriction on the change of the first file name is, for example, prohibition of the change. The first file name may not be completely changed, but may be a partial change restriction that allows a change other than the continuous description such as the serial number.

  In S78, it is determined whether or not the current file name change request is for the second file name. If the determination is positive, the process proceeds to S79, and if not, the routine is terminated. In S79, the second file name is allowed to be changed.

  The program to which the present invention is applied causes a computer to function as each unit of the file management apparatus 50. Another program to which the present invention is applied causes a computer to execute each step of the file management method 70.

  Although the present invention has been described with respect to various specific embodiments, the present invention is not limited to this, and each component in the various specific embodiments is modified (including deletion) without departing from the gist of the invention. And can be materialized. Various inventions can also be formed by replacing constituent elements between various specific forms or combining a plurality of constituent elements in various specific forms.
