  When the user designates a desired piece of music from among a large number of pieces of music in the audio device, it is convenient to designate a unique designator such as a file number assigned to each piece of music from the remote controller. However, when the number of songs is large, the user does not remember what the file number of the desired song is played, and intro play in order of the file number, and the intro of the desired song flows from the speaker. Sometimes it is necessary to instruct playback of the music, or to display a music list with file numbers on the display and to input the displayed file numbers from the remote control.

  When the number of music is enormous, searching for music by intro play takes an enormous amount of time. Although Patent Document 1 displays a music list on a display device, the display device of the audio apparatus has a few music pieces that can be displayed at a time, which is at most few, so that all the music items in the music list can be known from the display on the display device. The screen has to be scrolled or switched many times, which also takes an enormous amount of time like intro playback. The audio apparatus of Patent Document 1 can create a music list in which music is rearranged by item such as genre (FIGS. 6 to 8 of Patent Document 1), but the user-desired music is rearranged by item. There is no guarantee that it will be at the front of the list, and it is not possible to expect a reduction in the number of screen scrolls or switching until the desired music is displayed on the display.

  An object of the present invention is to provide a content processing apparatus, a content processing method, and a program that enable a user to efficiently grasp a specifier such as a file number input when a user specifies content for processing such as reproduction. Is to provide.

  According to the present invention, a unique (unique) specifier is given to the content of a recording medium that can be accessed by the content processing apparatus by mounting, connection, or incorporation, and a content list including specifier information Is created. The content list is in a format (eg, text format) that can be presented (eg, viewed and / or printed) to the user in the information processing apparatus, and the information processing device (eg, personal computer) is a content to the user. A list having a sufficiently high presentation performance than the content processing apparatus is selected. The content processing device performs predetermined processing (eg, reproduction) on the content associated with the specifier based on the input of the specifier from the user based on the presentation of the content list in the information processing device.

The content processing apparatus of the present invention processes content recorded on an accessible recording medium. The content processing apparatus includes the following means.
Specifier assigning means for assigning a unique specifier to each content recorded on the recording medium;

The content processing method of the present invention processes content recorded on an accessible recording medium. The content processing method includes the following steps.
A specifier giving step for giving a unique specifier to each content recorded on the recording medium;
A content list creation step for creating a content list in which content information including the specifiers assigned in the specifier giving step is listed for each content in a format that can be processed by an information processing device other than the content processing device;
An input receiving step for accepting a specifier input by a user based on a content list of a presentation processing result of the information processing device, and a content corresponding to the specifier received in the input receiving step is designated as a processing target content in the content processing device The specified step to be performed.

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

  According to the present invention, the content list for content stored in a recording medium accessible by the content processing device includes information on specifiers specific to each content, and an information processing device (for example, a personal computer) ) Is created in a format that can be presented, and content list information can be presented to the user in the information processing device by the content list presentation processing by the information processing device. In this way, even when the total number of contents becomes enormous, the user efficiently grasps the specifier for the desired content based on the content list of sufficiently high presentation processing by the information processing apparatus, and relates to the content. It becomes possible to instruct processing efficiently.

  FIG. 1 is a schematic configuration diagram of a stationary audio apparatus 10. The display unit 12 is provided on the front panel of the stationary audio apparatus 10 and displays at least text based on input data from the system microcomputer 11, and there are some that can also display an image. The operation unit 13 is provided in the main body of the stationary audio apparatus 10 and a remote controller, and information on keys operated by the user is sent to the system microcomputer 11.

  The CD mechanism unit 14 is loaded with a CD, accesses the part instructed by the control signal from the system microcomputer 11 to the loaded CD, and sends the data read from the part to the DSP 16. A built-in HDD / memory 15 (a recording medium such as a hard disk drive or a memory built in the stationary audio apparatus 10) 15 stores music in a compressed file such as MP3 or WMA, and is controlled by the system microcomputer 11. The file designated by the signal is accessed, and the read data is sent to the DSP 16.

  The memory card slot 21, USB controller 22, and USB controller 23 are each appropriately mounted or connected with a memory card (eg, SD card) 26, USB memory 27 and HDD / DAP (external HDD device or digital audio player) 28. The digital data read from them is sent to the DSP 16. The music data is also written in the compression format file such as MP3 in the memory card 26, the USB memory 27, and the HDD / DAP 28.

  The DSP 16 decodes digital data from the CD mechanical unit 14, built-in HDD / memory 15, memory card 26, USB memory 27 or HDD / DAP 28, and generates a digital audio signal. The DAC 32 converts the digital audio signal from the DSP 16 into an analog audio signal. The analog audio signal is amplified by the amplifier unit 33 and then sent to the speaker 34 to be output from the speaker 34 as reproduced sound.

  FIG. 2 is a flowchart of the content list file creation method 40. A distinction is made between content files and content list files. Specifically, the content file is a music file including a compression format such as MP3 or WMA. The content list file is a file containing a content list. The content list file creation method 40 is implemented as a program in the stationary audio apparatus 10 and executed.

  In the content list file creation method 40, (a) a content list file for content stored in each recording medium accessible by the stationary audio apparatus 10 is stored in the recording medium; ) The data may be stored in a predetermined recording medium that has been set. (A) corresponds to “same recording medium” in S43, and (b) corresponds to “predetermined recording medium” in S43. In the case of (a), a content list file is created for each recording medium, whereas in the case of (b), one content list file that covers all the songs on all the recording media is stored in the predetermined recording medium. To be created.

  In S41, it is determined whether or not list creation should be started. If the determination is negative, the content list file creation method 40 is immediately terminated, and if the determination is positive, the process proceeds to S42. The start of content list creation is, for example, when the user gives an instruction to create a list from the operation unit 13 or when executing S65 and S66 in the content list file update method 60 (FIG. 5) described later.

  In S42, it is determined whether there is a manageable content file in a recording medium such as the built-in HDD / memory 15 that can be accessed by the stationary audio apparatus 10, and if the determination is positive, the process proceeds to S43. If so, the content list file creation method 40 ends. For convenience of explanation, in order to distinguish the recording medium that is the basis of the positive determination in S42 from other recording media, it will be referred to as “target recording medium” as appropriate.

  In S43, the content list file is opened on the target recording medium or a predetermined recording medium different from the target recording medium. The content list file is a file for writing a content list. The content list file is, for example, a text format file, and can be browsed and printed by opening the content list file with an information processing apparatus such as a PC.

  In S44, a content file for which content information has not been acquired is searched for in the target recording medium, and the recording medium name (or drive name), folder name, file name, tag information, etc. are acquired for the content file. . The recording medium name and folder name for each content are used as path information. The tag information includes, for example, an album name, a song name, and an artist name. For example, in the case of an MP3 file, tag information can be obtained from an ID3 tag included in the file.

  In S45, a specifier associated with the content file is generated. The specifier is unique to the content, and specifically, the file number shown in FIGS. 3 and 4 to be described later. The file number is a serial number assigned in order from 1 to the content file that is currently accessible by the stationary audio apparatus 10. The file number is used as a numerical value to be input in the operation unit 13 when the user tries to reproduce desired content (the content is music in the stationary audio device 10) in the stationary audio device 10.

  In S46, the character code related to the information acquired in S44 and the specifier generated in S45 is optimized for the content, and output to the currently opened content list file. Here, “optimization of character code” means that when a content list is opened on a PC (personal computer) or the like and displayed on a PC display, each column related to each attribute of the content list on the screen is aligned. This is the process of inserting tags and spaces between data as appropriate.

  In S47, it is determined whether or not the content information of all content files in the target recording medium is included in the content list. If the determination is positive, the process proceeds to S49, and if not, the process proceeds to S48. In S48, the specifier is incremented by 1, and the process returns to S44. In S49, the content file is closed and the content list file creation method 40 is terminated.

  FIG. 3 and FIG. 4 are display examples when content files created by the content list file creation method 40 for each recording medium and for all recording media are displayed on the screen of the PC. The content list according to FIG. 3 is a content list of the internal HDD / memory 15, for example, among the content lists by recording medium. The predetermined disk according to FIG. 4 is a list-dedicated recording medium described in S64 of the content list file update method 60 (FIG. 5) described later.

  A PC that displays the content list of FIGS. 3 and 4 on the display is connected to the stationary audio device 10 via a LAN (Local Area Network) or USB (Universal Serial Bus), and the user goes to the stationary audio device 10. A content list file in the locally connected internal HDD / memory 15, memory card 26, USB memory 27, or HDD / DAP 28 can be accessed from a PC via a network. In the case of a content list file stored in a recording medium detachably attached to the stationary audio apparatus 10 such as the memory card 26, a network is required to display the content list of FIGS. 3 and 4 on the PC display. Instead of using the recording medium, the recording medium may be removed from the stationary audio apparatus 10 and attached to a compatible drive or the like of the PC, and the content list file of the recording medium may be directly read into the PC.

  Note that the content list file is created, for example, as a text file (XXX.txt) so that it can be read by a PC. Although not described in the content list file creation method 40, the item name of each column as an attribute is written in the content list file prior to the writing of the first piece of music information. In the example of FIGS. 3 and 4, the item name is File No. (File No.), File Name (file name), Folder Path (folder path), Album (album name), Title (music name), and Artist (artist name).

  The Folder Path (folder path) is path information used when accessing each content. Regarding the path information, since the content list in FIG. 3 is classified by recording medium, the path information of each content starts from the highest folder name of each recording medium, but the content list in FIG. Since all content lists are stored in a predetermined recording medium, the path information of each content indicates the name of the recording medium (drive name) in which the content is stored. Therefore, it starts with the recording medium name (drive name).

  In creating a content list file in text format, a space or tag is appropriately inserted between the horizontal data in the content list by optimizing the character code in S45 of the content list file creating method 40. As a result, the content is displayed on the PC screen. The data in each column of the list is aligned straight. Although the contents list of FIGS. 3 and 4 is only partially described due to space limitations, the user can operate the mouse with respect to the scroll key on the PC keyboard or the scroll bar at the right end of the screen in the text file editing software, The large-screen PC screen can be efficiently switched to an arbitrary part of the content list by moving the screen back and forth or jumping by setting shortcut keys in the text file editing software. The text file can be edited on a PC, and the user can use text file editing software to supplement the missing information part in the content list as appropriate, or to add the already described part to his / her favorite description. The contents can be changed as appropriate, and the edited contents can be stored in a recording medium.

  The user can know information about the content stored in the built-in HDD / memory 15 or the like based on the screen display of the PC much larger than the display unit 12 of the stationary audio apparatus 10. The user can further print a text file related to the content list in a printer that is locally or network-connected to the PC. The user can efficiently understand what content is stored in the internal HDD / memory 15 or the like by looking at the print result of the content list.

  As shown in FIG. 3 and FIG. 4, the content list includes a file No. associated with each content. Is described. When the user intends to reproduce the content, the file No. associated with the content desired to be reproduced in the content list. Is input at the operation unit 13. The system microcomputer 11 receives the input file number. An instruction signal for reading the content file related to the folder path associated with is sent to the built-in HDD / memory 15, memory card 26, USB memory 27 or HDD / DAP 28, and the playback sound of the content related to the read content file is received. Output from the speaker 34.

  The stationary audio apparatus 10 accesses the content file in parallel with the creation of the text file in the content list file creation method 40 in order to access the content file. Is created in a RAM (not shown, Random Access Memory) and stored. Then, the user uses the operation unit 13 to set the file number. Is input based on the RAM association information. Is detected and the content file in the detected folder path is accessed. The stationary audio apparatus 10 has a file No. in RAM. Instead of using the association information between the file path and the folder path, the content list file in the recording medium is read and the file number included in the content list file is read. It is also possible to use association information between a folder path and a folder path.

  FIG. 5 is a flowchart of the content list file update method 60. In the content list file update method 60, one content list file covering all the contents of all recording media to which the stationary audio apparatus 10 is connected is created, and the content list file is accessed. Updated whenever there is a change in possible recording media. The content list related to the content list file is the one shown in FIG.

  In S61, it is determined whether or not a new connection of the recording medium has been detected. The determination in S61 is repeated until the determination becomes positive, and the process proceeds to S62 as soon as the determination becomes positive. For convenience of explanation, the recording medium in which a new connection is detected will be referred to as “recording medium A” as appropriate. In S62, it is determined whether there is a content list in another connected recording medium, that is, a connected recording medium other than the recording medium A. If the determination is positive, the process proceeds to S63, and if not, Proceed to S64. For convenience of explanation, the recording medium determined to have the content list in S62 is referred to as “recording medium B”. In S 63, information about all contents stored in the recording medium A is added to the content list in the recording medium B. Specifically, the contents of the content list file are updated so that the content list file in the recording medium B includes content information about the contents of the recording medium A. After executing S63, the content list file update method 60 is terminated.

  In S64, it is determined whether or not the recording medium A is a recording medium dedicated to the content list. If the determination is positive, the process proceeds to S65, and if not, the process proceeds to S66. The recording medium dedicated to the content list is preset in the stationary audio apparatus 10 as a recording medium for storing a content list for all contents in all recording media accessible by the stationary audio apparatus 10. Is. The stationary audio apparatus 10 can set, for example, a predetermined memory card 26 as a recording medium dedicated to the content list. In general, the memory card 26 may store not only a content list file but also a large number of content files (specifically, music files). The memory card 26 is created, for example, when setting a folder with a specific name for storing a content list file as a recording medium dedicated to the content list. In S64, it is determined whether or not the recording medium A is a recording medium dedicated to the content list based on whether or not the recording medium A has a folder with the specific name.

  In S65, a content list is created in which all the contents of all the recording media that are currently accessible by the stationary audio apparatus 10 are created and stored in the recording medium A. In S66, a content list is created in which all the contents of all the recording media that are currently accessible by the stationary audio apparatus 10 are created, and this list is created as a predetermined recording medium (hereinafter, for convenience of explanation, the recording list is recorded). The medium is appropriately referred to as “recording medium C”). The recording medium C has, for example, a recording medium that is set to record a content list, such as the HDD / memory 15 built in the stationary audio apparatus 10, and the content that has been reproduced in the most recent predetermined period. The number of accesses during the most recent predetermined period (when content is reproduced continuously from the same recording medium, the number of accesses to the recording medium increases with respect to the reproduction of the second and subsequent contents. 1 is the largest recording medium or the recording medium having the largest free capacity.

  In S65, a single content list is created in which information about songs on all recording media that are currently accessible by the stationary audio apparatus 10 is created and stored in the recording medium A. The entire content list for each of the plurality of recording media may be stored in the recording medium A.

  FIG. 6 is a flowchart of a method 80 for directly printing a content list from the stationary audio apparatus 10. In the direct printing method 80, the content list can be directly printed on the printer from the stationary audio apparatus 10 instead of being displayed or printed on the PC for user browsing. In this case, the stationary audio apparatus 10 is equipped with a printer driver, and the printer is connected to the stationary audio apparatus 10 via a network or locally.

  In S81, it is determined whether or not the printer output should be started. If the determination is positive, the process proceeds to S82, and if not, the direct printing method 80 is immediately terminated. The printer output of the content list from the stationary audio apparatus 10 is started, for example, when the user instructs printing of the content list from the operation unit 13. S82 to S87 respectively correspond to S42 and S44 to S48 of the content list file creation method 40 of FIG. In S42 and S44 to S48 of the content list file creation method 40, information with a specifier for each content is output to the content list file, whereas in S82 to S87 of the direct print method 80, designation for each content is performed. The child information is output to a printer driver, that is, a printer.

  In S82, it is determined whether there is a content file that can be managed on a recording medium that is accessible from the stationary audio apparatus 10. If the determination is positive, the process proceeds to S83. If so, the direct printing method 80 is terminated. In S83, information (for example, a recording medium name, a folder name, and tag information exemplified in FIGS. 3 and 4) is acquired for one content file for which information has not been acquired.

  In S84, a specifier associated with the content file is set. In S85, the character code of the information acquired in S83 and the specifier set in S84 is optimized, and then output to the printer driver. As a result, one line of the content list of FIG. 3 or FIG. 4 is output from the printer connected to the stationary audio apparatus 10.

  In S86, it is determined whether or not the output of S85 has been completed for all the content files. If the determination is positive, the direct printing method 80 is terminated. If the determination is negative, the process proceeds to S87. In S87, the specifier is incremented by 1, and the process returns to S83.

  FIG. 7 is a block diagram of the content processing apparatus 100. The above-described stationary audio apparatus 10 is a specific example of the content processing apparatus 100. The content handled by the content processing apparatus 100 is not limited to audio content such as music, and includes all content that can be reproduced, such as video. The content processing apparatus 100 is not limited to a stationary type and may be a portable type. The content processing apparatus 100 includes a specifier assigning unit 101, a content list creating unit 102, a specifier input receiving unit 103, and a specifying unit 104. The content processing apparatus 100 can further include a processing unit 107, a storage unit 108, a driving unit 109, and a print instruction unit 110. The content processing apparatus 100 processes content recorded on the accessible recording medium 113. The content processing is, for example, processing for selecting content or reproducing the selected content.

  The specifier assigning unit 101 assigns a unique (unique) specifier to each content recorded on the recording medium 113. The content list creating means 102 can present and process the content list 114 that lists the content information including the specifier assigned by the specifier assigning means 101 to each content by the information processing apparatus 115 other than the content processing apparatus 100. Create in the correct format.

  The specifier input receiving unit 103 receives a specifier input by the user based on the content list of the presentation processing result of the information processing apparatus 115. The designating unit 104 designates content corresponding to the designator accepted by the designator input accepting unit 103 as processing target content in the content processing apparatus 100.

  Specific examples of the content list 114 are those shown in FIGS. The file numbers in FIGS. 3 and 4 are examples of specifiers, and are assigned consecutive numbers starting from 1 for all contents on all recording media. The specifier is not limited to a sequential number, and is not limited to a numerical value. The processing target content in the specifying unit 104 is, for example, a playback target content. The recording medium 113 is typically a plurality, but may be one. Specific examples of the recording medium 113 include the built-in HDD / memory 15, the memory card 26, the USB memory 27, or the HDD / DAP 28 shown in FIG.

  A specific example of the information processing apparatus 115 is typically a PC (personal computer) or a printer. The information processing apparatus 115 such as a PC is usually equipped with a display larger than the display of the content processing apparatus 100. The printer may be one that is locally connected to the PC, one that is connected to the content processing apparatus 100 and the information processing apparatus 115 on the same network, or one that is locally connected to the content processing apparatus 100. The network is not limited to connection using a LAN cable, but may be connection using a wireless LAN.

  The format in which the information processing device 115 other than the content processing device 100 can process the content list 114 is, for example, the file format of the content list file is text format, HTML (HyperText Markup Language) format, XML (Extensible Markup Language) ) Format or PDF (Portable Document Format) format. When the PC as the information processing apparatus 115 has already installed predetermined word processing software and spreadsheet software, the predetermined file format can be adopted as the file format.

  As the capacity of the recording medium 113 increases, the content posted on the content list 114 becomes enormous and the size of the content list 114 also increases. However, instead of the display device of the content processing device 100, the user efficiently views the content information with a large number of specifiers by viewing the content list 114 from the display device or as a printed material in the information processing device 115, The specifier assigned to the desired content can be known efficiently.

  Preferably, the content processing apparatus 100 further includes a processing unit 107. The processing unit 107 accesses and processes the content specified by the specifying unit 104 based on the path information. The path information on which the processing unit 107 is based on access is read from the content list 114 or stored separately from the content list 114. For example, in parallel with the creation of the content list 114 by the content list creation unit 102, path information-content association information is extracted from the content list 114, and the content processing apparatus 100 is in a RAM or the like for the duration of power-on. If stored in a recording medium, when a user designates a specifier for playback, the path information associated with the specifier can be detected quickly without opening a content file. it can.

  Preferably, the content processing apparatus 100 further includes a storage unit 108. The storage unit 108 stores the content list 114 created by the content list creation unit 102 in the recording medium 113. The content list 114 stored by the storage unit 108 has a file format that can be processed by the information processing apparatus 115.

  The content list creation unit 102 may create a content list 114 for the contents stored in each recording medium 113, or one content covering all the contents of the plurality of recording media 113. List 114 may be created. In the former case, the storage unit 108 stores the content list 114 created by the content list creation unit 102 for each recording medium in each recording medium, or stores them in a predetermined recording medium. To do. In the latter case, the storage means 108 is preferably stored in a predetermined one recording medium 113. Specific examples of the predetermined one recording medium 113 are the recording medium B in S63, the recording medium A in S65, or the recording medium C in S66 of the content list file update method 60 (FIG. 5).

  The content processing apparatus 100 recognizes information indicating that the recording medium 113 stores the content list 114 (eg, a folder having a predetermined name indicating a folder storing the content list 114) in the predetermined recording medium 113. Can be recorded as possible. The content list creation unit 102 creates the content list 114 when a predetermined recording medium 113 is recognized by the content processing apparatus 100.

  Preferably, the content list creation unit 102 updates the content list 114 every time the recording medium 113 accessible by the content processing apparatus 100 is changed or every time the content recorded on the recording medium 113 is changed. To do. The storage unit 108 stores the updated content list 114 in the corresponding recording medium 113 every time the content list is updated. The content recorded on the recording medium 113 is changed, for example, when the user deletes, moves, or adds the content in the recording medium 113.

  The processing of the content list by the information processing apparatus 115 can include displaying the content list 114 on the display of the information processing apparatus 115 or printing from the information processing apparatus 115. Then, the information processing apparatus 115 reads the content list 114 stored in the recording medium 113 through a network connection to the content processing apparatus 100 or a local connection in the information processing apparatus 115, and displays it on the display of the information processing apparatus 115. Printing is performed from the display or information processing apparatus 115.

  The content processing apparatus 100 can further include a driving unit 109 and a print instruction unit 110, and the information processing apparatus 115 can be a printer connected to the content processing apparatus 100. The driving unit 109 drives the printer. The print instruction unit 110 instructs the printer to print the content list 114 using the driving unit 109. The drive unit 109 is, for example, a printer driver installed in the content processing apparatus 100, and outputs the content list 114 as a control code to the corresponding printer. The printer driver may be set in the information processing apparatus 115 in advance, or a printer driver corresponding to the printer used for printing may be acquired and set via a network or the like.

  The content list creation unit 102 creates a content list 114 for the content stored in each recording medium 113, and the print instruction unit 110 prints the content list 114 for each recording medium 113 individually. You may instruct. In addition, the content list creation unit 102 creates a content list 114 that is a collection of contents stored in a plurality of recording media 113, and the print instruction unit 110 prints the content list 114 that is a collection. This may be instructed to the printer.
