Description

  The present invention relates to a playlist editing apparatus, a playlist editing method, a playlist editing program, and a recording medium storing a playlist editing program, which are created by selecting arbitrary contents from contents such as a plurality of music pieces.

  A playback device that plays back a content selected from a plurality of contents (for example, music data) recorded in a storage means such as a hard disk or a non-volatile memory creates a playlist that is a list of the selected contents Then, the content included in the playlist is continuously reproduced in the designated reproduction order.

  The playlist is generated when the user sequentially selects desired contents from the contents recorded in the storage means. Recently, the storage capacity of the storage means has increased, and as a result, the number of contents to be recorded tends to increase. Therefore, the user needs to select a desired content from a vast number of contents, and a playlist The operation of creating is very cumbersome. In addition, not only one playlist but also a plurality of playlists are often created so that the content to be reproduced can be changed according to the user's mood. In this case, the user needs to create a plurality of playlists, which is more complicated and troublesome.

  For this reason, it has been proposed to automatically generate a playlist without bothering the user. For example, in Patent Document 1, when at least one playlist is generated by user operation and stored in the HDD 5, the analysis unit 2A analyzes the playlist stored in the HDD 5, and generates a playlist information table. To do. It is described that the generation unit 2B generates a new playlist based on the playlist information table.

Patent Document 2 discloses a target storage medium registered in advance by a user as a playlist registration condition 2b among storage media (internal storage medium 6 and external storage medium 7) that are connected to or accessible to the information reproducing apparatus 10. For one or more storage media corresponding to 2b ₁ , all contents stored in the respective storage media are searched, and metadata matching target metadata 2b ₂ registered in advance as playlist registration conditions 2b is included. It describes that a playlist 2a in which reproduced content is registered is automatically and quickly created by extracting the content and registering it in the playlist 2a.

  However, the content list generation device described in Patent Document 1 has a problem that the processing is complicated because the generated playlist needs to be analyzed. In addition, it is not possible to accurately reflect the user's preference because it is not known exactly what purpose the user created the playlist (how the selected song was selected or deleted). was there. Further, the playlist creation method described in Patent Document 2 has a problem that it takes time and effort for the user to set conditions in advance.

  Therefore, the present invention stores a playlist editing device, a playlist editing method, a playlist editing program, and a playlist editing program that can be edited into a playlist that reflects the user's preference without requiring the user to take time and effort. It is an object of the present invention to provide a recorded medium.

  In order to solve the above-described problem, the playlist editing device according to claim 1, wherein a content recording unit in which metadata indicating a plurality of contents and attribute information of the contents is recorded, and the metadata based on the metadata Display means for displaying a content list including attribute information of content, operation means for performing selection operation for selecting the content from the content list displayed on the display means, and the content selected by the operation means A playlist editing unit that adds or deletes a playlist to edit the playlist, wherein the playlist editing unit is configured to select the content based on a selection operation in the operation unit. It is characterized by determining registration conditions for registering the list.

The playlist editing program according to claim 13, wherein a content recording unit stores a plurality of contents and metadata indicating the attribute information of the contents, and a content list including the attribute information of the contents based on the metadata Display means for displaying, an operation means for performing a selection operation for selecting the content from the content list displayed on the display means, and a playlist by adding or deleting the content selected by the operation means A playlist editing program for causing a computer to function as a playlist editing means for performing editing, wherein the playlist editing means registers the content in the playlist based on a selection operation in the operating means. It is characterized by determining the registration conditions of There.

It is a block diagram of a playlist editing apparatus according to an embodiment of the present invention. It is explanatory drawing of the screen displayed on the display part of the playlist editing apparatus shown by FIG. 3 is a flowchart of a playlist creation operation in the playlist editing apparatus shown in FIG. It is explanatory drawing which showed the operation | movement at the time of the selection range change of the playlist editing apparatus shown by FIG. It is explanatory drawing which showed the operation | movement at the time of the selection range change of the playlist editing apparatus shown by FIG.

  Hereinafter, a playlist editing apparatus according to an embodiment of the present invention will be described. The playlist editing apparatus according to an embodiment of the present invention is based on a selection operation for the playlist editing unit to select content in the operation unit from a content list including content attribute information based on metadata. Since the registration conditions for registering the content in the playlist are determined, the registration conditions estimated based on the contents that the user has clearly intended and operated are set, and the playlist is edited based on the registration conditions. Thus, it is possible to edit the playlist to reflect the user's preference without requiring the user to take time and effort.

  Further, the playlist editing unit may perform playlist editing by adding the content selected by the operation unit from the content list of the content stored in the content storage unit to the playlist to be edited. In this way, content to be added can be selected from the content list, so that the user can easily edit the playlist.

  Further, the playlist editing means may perform the playlist editing by deleting the content selected by the operation means from the content list of the playlist to be edited from the playlist to be edited. In this way, the content to be deleted can be selected from the content list, so that the user can easily edit the playlist.

  The selection operation in the operation means includes an operation for specifying any attribute information as specific attribute information from the metadata included in the content list, and the display means is a content whose display mode is changed based on the specific attribute information. The list may be displayed, and the playlist editing means may determine the registration condition based on the specific attribute information in the content selected from the content list whose display mode has been changed. By doing so, it is possible to obtain a playlist having playlist registration conditions estimated based on an operation of selecting content information whose display mode has been changed by specifying arbitrary attribute information from metadata. .

  The display means may display a content list in which the content has been rearranged or narrowed based on the specific attribute information. By doing in this way, it is possible to display a content list in which a plurality of contents are rearranged or narrowed down by the operating means, and to select the content that the user is paying attention to.

  Further, the display means displays the content list on which the content is rearranged based on the specific attribute information, and the selection operation on the operation means is continuously arranged in the rearranged content list. The playlist editing means may register the content belonging to the range of the specific attribute information in the selected plurality of continuously arranged contents as a registration condition. . In this way, content belonging to the range of the specific attribute information selected from the content list can be registered, user operations can be faithfully reflected in the playlist, and user preferences are reflected. be able to.

  In addition, the playlist editing means includes content other than the plurality of selected consecutively arranged contents that are included in the content list and have specific attribute information within the range. The registration condition may be that the content is excluded from the playlist registration target. In this way, it is possible to set a registration condition that content that is not selected even though the specific attribute information is within the range can be set as a registration condition, and the user's operation can be faithfully reflected in the playlist. It is possible to reflect the user's preference.

  In addition, when the plurality of selected consecutively arranged contents are equal to or less than the predetermined number, the playlist editing means specifies that each of the selected plurality of contents is registered in the playlist. The registration condition may be given priority over the range. In this way, for example, it is determined whether or not the user clearly intends to add to the registration condition the content of adding a song included in the range of the specific attribute information such as only one selected content. If it is difficult, it is possible to reliably reflect the user's preference by using a registration condition that prioritizes the content name (eg, song title) over the range.

  Further, the selection operation in the operation means includes a batch selection operation for selecting a plurality of contents arranged in succession, and the playlist editing means includes a plurality of selected contents after the batch selection operation. When the selection of at least one content is canceled, the registration condition is to register the content belonging to the range of the specific attribute information in the plurality of contents selected at once, and the selected content is It may be added to the registration condition to be excluded from the registration target. By doing so, it is possible to accurately reflect the user's intention to cancel the selection.

  Further, when at least one content other than the selected plurality of contents is further selected after the batch selection operation, the playlist editing means belongs to the range of the specific attribute information in the plurality of contents selected at once. While registering content may be a registration condition, adding selected content to the registration target may be added to the registration condition. In this way, the user's intention of additional selection can be accurately reflected.

  Moreover, the playlist editing means may perform the playlist editing based on the registration condition. By doing in this way, it can edit to the play list reflecting a user preference based on the registration conditions registered based on selection operation in an operation means.

  The playlist editing method according to an embodiment of the present invention determines playlist registration conditions based on a selection operation for selecting content from a content list including content attribute information based on metadata. Therefore, it is possible to set the registration conditions estimated based on the contents that the user has clearly intended and operated, and to edit the playlist based on the registration conditions, and without making the user troublesome. Can be edited into a playlist that reflects the user's preferences.

  The playlist editing program according to an embodiment of the present invention is based on a selection operation for the playlist editing unit to select content in the operation unit from a content list including content attribute information based on metadata. Since the registration conditions for registering the contents in the playlist are determined, the registration conditions estimated based on the contents that the user has clearly intended and operated are set, and the playlist is edited based on the registration conditions. The user can edit the playlist to reflect the user's preference without taking the user time and effort.

  Further, the above-described playlist editing program may be stored in a computer-readable recording medium. In this way, the program can be distributed as a single unit in addition to being incorporated in the device, and version upgrades can be easily performed.

  An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, a music player 1 as a content playback apparatus according to an embodiment of the present invention includes a CPU 2, a memory 3, a display unit 4, an input unit 5, a playback unit 6, and a recording medium 7. And. The CPU 2, the memory 3, the display unit 4, the input unit 5, the playback unit 6, and the recording medium 7 are connected to the bus B.

  The CPU 2 serving as a playlist editing unit operates in accordance with a control program recorded in a ROM or the like of the memory 3 and manages overall control such as reproduction and display of the music player 1. Further, the CPU 2 adds the music data 7a selected from the list of music data 7a stored in the storage medium 7 to the playlist to be edited based on an operation input from the input unit 5 to be described later. The list 7c is edited.

  The memory 3 includes a RAM, a ROM, and the like. The ROM stores a control program for operating the CPU 2, and the RAM temporarily stores various data as a work area when the CPU 2 operates.

  The display unit 4 as a display unit is configured by a liquid crystal display, for example, and outputs and displays the result processed by the CPU 2 for the user.

  The input unit 5 as an operation unit includes an input unit such as an operation button or a touch panel (not shown) and notifies the CPU 2 of an instruction from the user.

  The playback unit 6 includes a decoder, a DA converter, an amplifier, and the like, and plays back the content (music data 7a) recorded on the recording medium 7 based on the control from the CPU 2 and outputs it to an external speaker or the like. .

  A recording medium 7 as content recording means is composed of, for example, a hard disk drive (HDD), an optical disk, or a nonvolatile memory, and music data 7a as content to be played back by the music player 1 and tag data 7b as metadata. , A play list 7c is recorded.

  The music data 7a is music data reproduced by the music player 1, and is encoded and recorded by a predetermined method for each music. In the tag data 7b, items such as title, artist, genre, number of reproductions, release year, BPM (Beats Par Minute) are recorded as attribute information of the music data 7a for each music. The tag data 7b may be acquired along with the music data 7a, or may be acquired separately from an external network or the like by being configured to be connectable to an external network (not shown). The playlist 7c is a list configured by registering music arbitrarily selected from all the music recorded on the recording medium 7, and there may be a plurality of playlists according to registration conditions.

  Among the above-described configurations, the CPU 2, the memory 3, the display unit 4, the input unit 5, and the recording medium 7 constitute the playlist editing apparatus 10 according to an embodiment of the present invention.

  Next, an example of a screen displayed on the display unit 4 when creating a playlist will be described with reference to FIG. A screen displayed when an operation such as playlist editing is input from the input unit 5 to the display unit 4 includes a library area 4a, a narrowing area 4b, and a detailed area 4c.

  The library area 4a displays the name of a library composed of a plurality of songs. For example, all songs are a library including all songs recorded on the recording medium 7. A playlist 7c is also included in the library, and two playlists, playlist 1 and playlist 2, are created in FIG.

  In the narrowed-down area 4b, for example, information in the library selected for each item of the tag data 7b such as a genre, an artist, and an album is displayed, and music can be narrowed down by selecting arbitrary information among these. . For example, in FIG. 2, genre, artist, and album are displayed as items, and rock and pop are displayed as information in the genre. If the genre lock is selected here, only the music whose genre in the selected library is locked is narrowed down and displayed in the detailed area 7c described later.

  In the detail area 4c, the contents of the library selected in the library area 4a are displayed in a list (content list). Specifically, items in the tag data 7b are displayed in a column direction, and information on each item is displayed in one line for each music piece. For example, in FIG. 2, the title, artist, album, genre, number of playbacks, and BPM are displayed in the column direction as the item 4c1, and information on each item is displayed for each song. Further, by selecting (specifying) the item 4c1 in the detailed area 4c, the information of the selected item is sorted (assorted) in ascending order or descending order and displayed. For example, when BPM is selected, the music is displayed in the order in which the BPM values are sorted in ascending or descending order as the specific attribute information. That is, the list in which the music is rearranged based on the specific attribute information is displayed.

  Next, an outline of a playlist creation operation in the playlist creation device 10 having the above-described configuration will be described. In this embodiment, the playlist registration condition is determined based on an operation when the user selects a song from the content list displayed in the detail area 4c and adds it to the playlist 7c. That is, the registration condition of the playlist 7c of the music data 7a is determined based on the selection operation at the input unit 5. The playlist registration condition is for automatically adding an additional song to the playlist 7c when the song data 7a is added to the library (all songs) after the condition is set and the condition is met. This condition is included in the playlist 7c. Further, when the playlist 7c including the playlist registration condition is distributed to other users, the music that matches the playlist registration condition is selected from the library of the other user.

  When a user adds music to the playlist 7c, first, an arbitrary library is selected from the library area 4a in order to determine a content list to be displayed in the detailed area. Here, a library other than the playlist 7c to be edited is selected. Secondly, the narrow-down area 4b or the item 4c1 is selected to narrow down or rearrange the content list displayed in the detailed area 4c. Third, an arbitrary piece of music is selected from the content list whose display mode has been changed by narrowing down or rearranging. Fourthly, it is often performed from four operations of specifying (or newly creating) the playlist 7c to be added and adding an arbitrary selected piece of music. Therefore, in the present embodiment, the tag data 7b (specific attribute information) that is noticed when the user adds music to the playlist 7c from the above operation is specified, and the display mode is changed based on the tag data 7b. The playlist registration conditions are determined based on the specific attribute information in the music selected from the displayed content list.

  Next, the playlist creation operation described above will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG.

  First, in step S1, the library name selected in the library area 4a is temporarily stored in the memory 3 as information 1, and the process proceeds to step S2.

  Next, in step S2, the item name selected in the item 4c1 in the detailed area 4c or the narrowed area 4b is temporarily stored in the memory 3 as information 2, and the process proceeds to step S3. That is, step S2 is a process for specifying by which item in the tag data 7b the content list of the library selected in the library area 4a is narrowed down or rearranged.

  Next, in step S3, the range of items in the music selected in the detail area 4c is temporarily stored in the memory 3 as information 3, and the process proceeds to step S4.

  Next, in step S4, the music in the selected range is added and the playlist 7c is edited. At this time, information to be added is temporarily stored in the memory 3 as information 4, and the process proceeds to step S7. When adding a song to the playlist 7c, first, an addition source (all songs, etc.) is specified, then a song to be added is specified, and an addition destination (playlist 1, etc.) is specified. Accordingly, since the addition destination is determined in step S4, the addition destination determined in step S4 is also added as information 1, that is, the playlist 7c to be edited.

  Next, in step S5, information 1 to information 4 temporarily stored in the memory 3 in steps S1 to S4 are combined and stored in the playlist 7c edited as a playlist registration condition. The playlist 7c in which the playlist registration condition is set evaluates the registration condition every time a song is added to the library, and a song that matches the registration condition is automatically or at the time of registration by the user. Is added to the playlist 7c. That is, the playlist 7c is edited based on the playlist registration conditions. Further, by repeating this flowchart every time the playlist 7c is edited, playlist registration conditions for the edited playlist 7c are accumulated.

  The specific operation example of the flowchart described above will be described. With all songs selected as a library in FIG. 2, BPM is selected as item 4c1, sorted by BPM, and titles BB to II are selected and played. When the information is added to the list 1, first, “playlist 1 from all songs” as information 1, “BPM” as information 2, “100 to 101” which is BPM information of titles BB to II as information 3 “Add” is extracted as “4”, and “Add a song having a BPM of 100 to 101 to the playlist 1 from all songs” is set as a registration condition of the playlist 1. That is, when the list in which the music data 7a is rearranged based on the specific attribute information is displayed on the display unit 4 and a plurality of music data 7a arranged in succession in the list is selected, The playlist registration condition is to add music data 7a belonging to the range of the specific attribute information in the plurality of music data 7a that are continuously arranged.

  Further, it may be narrowed down in the narrowed down area 4b without sorting in the item 4c1 of the detailed area 4c. For example, when all the songs are selected as the library, and the genre lock is selected and narrowed down in the narrowing area 4b, and the genre displayed in the detailed area 4c is selected as the rock title and added to the playlist 1, First, “playlist 1 from all songs” is extracted as information 1, “genre” is extracted as information 2, “rock” is extracted as information 3, and “addition” is extracted as information 4. Is added as a registration condition for the playlist 1. Further, this narrowing method is not limited to the narrowed area 4b, and may be performed by a search operation. For example, although not shown in FIG. 2, if a search area or the like is provided, a keyword included in the tag data 7b such as aaa, XXX, or lock is input from the search area, and the keyword is used as the tag data 7b. You can narrow down the list by displaying a list of songs you have.

  Also, for example, when all the songs are selected as the library and BPM is selected as the item 4c1, when the titles BB to DD are selected and added to the playlist 1, "add songs with 100 BPM from all songs" In addition to the condition “Yes”, the condition “Exclude title EE” is also added, and the condition is “Add music with BPM of 100 from all songs but exclude title EE”. That is, in the case where there is music data 7a other than the plurality of music data 7a that are included in the content list and selected and arranged in sequence, and the specific attribute information is within the range, The playlist registration condition is that the music data 7a is excluded from the addition target (registration target) of the playlist 7c.

  Further, in the case of the above example, “Titles BB, CC, and DD are added out of songs having a BPM of 100 from all songs” may be used. That is, when the number of the selected music data 7a arranged in succession is equal to or less than the predetermined number, the BPM indicates that each title of the selected music data 7a is added to the playlist 7c. The playlist registration condition has priority over the range.

  In these two examples, it is only necessary to determine whether to add a title selected according to the number of songs whose BPM is 100 or to exclude a title not selected. For example, if there are 10 BPM songs and only one song is not selected, it can be said that the user's intention to remove only that song is clear. If there are 10 out of 100 music pieces and only 3 music pieces are selected, it can be said that the user's intention to select those three music pieces is clear, and therefore the selected title is added.

  Also, for example, as shown in FIG. 4, with all songs selected as the library and BPM selected as the item 4c1, the titles BB to II are selected at once, and then only the title II is removed from the playlist. In the case of adding to 1, it is assumed that “music with a BPM of 100 to 101 is added from all music, but title II is excluded”. Since it can be said that the user's intention to remove title II is clear because the user has performed the operation of removing title II after selecting it, playlist registration conditions are set faithfully to that operation. That is, when the selection of at least one piece of music data 7a among the plurality of pieces of music data 7a selected after the batch selection operation is canceled, it belongs to the range of the specific attribute information in the plurality of pieces of music data 7a selected at once. The addition of the music data 7a is used as a playlist registration condition, and the addition of the music data 7a whose selection is canceled is added to the playlist registration condition.

  Also, for example, as shown in FIG. 5, with all songs selected as a library and BPM selected as item 4c1, titles BB to EE are selected once, then titles FF and GG are additionally selected and played. When added to the list 1, it is assumed that “a song having a BPM of 100 is added from all songs, and titles FF and GG are also added”. This is because the user performs an operation of adding a title FF and a GG other than 100 after the BPM selects a song whose BPM is 100, and thus the playlist registration condition is set faithfully to the operation. That is, when at least one piece of music data 7a other than the selected music data 7a is further selected after the batch selection operation, the music belonging to the range of the specific attribute information in the plurality of music data 7a selected at once. Adding the data 7a is a playlist registration condition, and adding the selected music data 7a to the addition target is added to the playlist registration condition.

  According to the present embodiment, the playlist registration condition is determined based on an operation when the user adds music to the playlist 7c, that is, an arbitrary item (attribute information) is selected from the tag data 7b included in the content list. It is specified as specific attribute information, and a content list whose display mode has been rearranged or refined based on the specific attribute information is displayed, and the specific attribute information in the content selected from the content list whose display mode has been changed is displayed. Since the playlist registration conditions are determined on the basis of this, the operation of performing sorting or narrowing by the item such as the genre of the tag data 7b, or the range of the items from the result of sorting or narrowing down, and the song data Since the operation for selecting 7a can be set as a playlist registration condition, it is based on the contents that the user has specifically intended to operate. It has set the playlist registration conditions, the play list that is based on the registration conditions to be able to edit, to not let the hassle to the user, it is possible to edit the play list that reflects the preferences of the user.

  In addition, when the list in which the music data 7a is rearranged based on the specific attribute information is displayed on the display unit 4 and a plurality of music data 7a arranged continuously in the list is selected, Since the playlist registration condition is to add the music data 7a belonging to the range of the specific attribute information in the selected plurality of music data 7a arranged in succession, the range of the specific attribute information selected from the list is Playlist registration conditions can be set, user operations can be faithfully reflected in the playlist, and user preferences can be reflected.

  In addition, when there is music data 7a other than the plurality of music data 7a selected and continuously arranged included in the content list, and the specific attribute information is within the range, Since the playlist registration condition is that the music data 7a is excluded from the addition target of the playlist 7c, the playlist registration condition that the music data 7a that is not selected while the specific attribute information is within the range is intentionally removed from the selection. Can be set, the user's operation can be faithfully reflected in the playlist, and the user's preference can be reflected.

  In addition, when the selected plurality of music data 7a arranged in succession is equal to or less than a predetermined number, the BPM indicates that each title of the selected music data 7a is registered in the playlist 7c. Since the playlist registration condition has priority over the range, for example, the user may add to the playlist registration condition the content of adding a song included in the range of the specific attribute information such as only one selected song data 7a. When it is difficult to determine whether the operation is a clearly intended operation, it is possible to reliably reflect the user's preference by using a title or the like as a playlist registration condition rather than a range.

  Further, when the selection of at least one of the selected plurality of songs is canceled after the batch selection operation, the song data 7a belonging to the range of the specific attribute information in the plurality of selected songs is added. This is the playlist registration condition, and the playlist registration condition is that the music that has been deselected is excluded from the addition target, so that the intention of the user to deselect can be reflected.

  Further, when at least one song other than the selected plurality of songs is further selected after the batch selection operation, the song data 7a belonging to the range of the specific attribute information in the plurality of songs selected at once is added. Is added to the playlist registration conditions, and the user's intention of additional selection can be reflected.

  In the above-described embodiment, an example of adding a song as an operation for registering a song in a playlist has been shown. However, the same applies to the case of deletion (not added). The deletion condition is also included. For example, when the playlist 1 is selected as the library, and the displayed titles EE and FF are selected and deleted in the narrowed-down area 4b by selecting YYY of albums, first, “play” “List 1” is extracted as “Information 2”, “Album” is extracted as Information 3, “YYY” is extracted as Information 4, and “Delete” is extracted as Information 4, and “Playlist 1 does not add songs whose album is YYY” is the playlist. 1 as a registration condition. Therefore, when the user deletes a music piece from the playlist, the playlist registration condition can be set based on the content that the user has clearly intended and operated, and can be edited into the playlist based on the registration condition. .

  In the above-described embodiments, the range of the specific attribute information has been described by items that can be expressed by a numerical range called BPM. However, in the case of items that are not expressed by numerical values such as genres, artists, albums, etc. The items can be made a range by enumerating the items.

  Further, the playlist 7c created in the above-described embodiment can be used when selecting a song from another playlist 7c as well as all the songs as a library. Further, by distributing to other users alone via a network or other recording medium, the music suitable for the playlist 7c can be selected from the library of the other user and can be reproduced.

  In the above-described embodiment, the music data has been described as the content. However, the present invention can be applied to video data as long as metadata such as tag data can be acquired.

  Further, the present invention can be configured as a playlist editing program by making each block constituting the playlist editing apparatus 10 described above a program that operates on a computer.
