Description

  The present invention relates to an information processing apparatus, an information processing method, and an information processing program. More specifically, the present invention relates to an information processing apparatus, an information processing method, and an information processing program for reproducing information recorded on a recording medium.

  Conventionally, audio information recorded on one CD-DA is usually about one hour. Therefore, if the audio information is music, a maximum of about 10 songs can be recorded on the CD-DA. It was easy enough to manually select the music to be played back and recorded.

  However, a storage device having a larger storage capacity than the conventional CD-DA becomes cheaper, and when a technology for compressing information is applied, the number of information that can be stored in a single storage medium is considered to increase dramatically. If the information is audio information, several thousand audio information can be stored in a single storage device. It is very difficult to manually select audio information to be reproduced and recorded from several thousand audio information.

  The present invention has been made in view of the above facts, and provides an information processing apparatus, an information processing method, and an information processing program capable of efficiently recording and reproducing a large amount of information recorded on a recording medium. Objective.

  In order to achieve the above object, an information processing apparatus according to the present invention provides a plurality of second identification information and a plurality of second identification information respectively associated with a plurality of first identification information and a plurality of first identification information. One of the storage means for storing the associated content data, the display means for displaying the first identification information and the second identification information, and the plurality of first identification information displayed by the display means is a selection operation. Display control means for displaying a plurality of second identification information associated with the first identification information selected with reference to the storage means on the display means.

  In the information processing method according to the present invention, the storage means stores a plurality of pieces of first identification information and a plurality of pieces of second and second pieces of identification information associated with the plurality of pieces of first identification information. When the display means displays the first identification information and the second identification information, and when any one of the plurality of first identification information displayed by the display means is selected by the selection operation, And displaying a plurality of second identification information associated with the first identification information selected with reference to the storage means on the display means.

  The information processing program according to the present invention stores in the storage means a plurality of first identification information and a plurality of second and second identification information associated with the plurality of first identification information, respectively. When any one of the process to display, the process to display the first identification information and the second identification information on the display unit, and the plurality of first identification information displayed by the display unit is selected by the selection operation, And displaying the plurality of second identification information associated with the first identification information selected with reference to the storage means on the display means.

  The storage means stores first identification information, a plurality of second identification information associated with the first identification information, and content data associated with each second identification information. The first identification information is information identifying a set of tracks or information identifying an artist, for example, and the second identification information is information identifying a track, for example. The first identification information and the second identification information are displayed on the screen of the display means. When any one of the plurality of first identification information displayed on the screen of the display means is selected by the user, the display control means is associated with the first identification information selected and operated with reference to the storage means. A plurality of second identification information is displayed on the screen of the display means.

  Thus, in order to search a large number of content data recorded in the storage means, the second identification information associated with the content data and the first identification information associated with a plurality of second identification information are used. Content data can be efficiently recorded and reproduced.

  Even when tracks having the same name exist in different albums, the list can specify the track. Furthermore, audio information can be recorded, reproduced, and output in the order in which the identification information is registered in the list.

  According to the present invention, the second identification information associated with the content data and a plurality of first identification information associated with the second identification information are used to search a large number of content data recorded in the storage means. Therefore, it becomes easy to search for the second identification information, and content data associated with the second information can be efficiently recorded and reproduced.

Hereinafter, the present embodiment will be described in detail with reference to the drawings.
[Hardware configuration]
FIG. 1 shows an external appearance of the information recording control apparatus according to the present embodiment from the front. This information recording control device incorporates a hard disk (not shown). In this example, a hard disk of 8.4 GB (about 140 hours during music playback) is used, but it can be accessed at high speed equivalent to a hard disk with a capacity other than 8.4 GB or hard disk, and high-speed playback is possible. Other digital information recording devices may be used.

  The apparatus also includes a CD drive 2 for reproducing a CD, a CD-R drive 4 for recording information on a CD-R, and a PC card drive 10 for recording information on a compact flash (registered trademark). In addition, various memory cards such as a multimedia card and a memory stick that can be connected to the apparatus via the PC card drive 10 and a digital storage device can be used. In addition to the PC card drive, a serial cable port, an infrared port, or the like may be provided as a connector for transmitting information.

  Furthermore, this apparatus is provided with a liquid crystal display 6 that serves as an interface with the user. The user can operate the apparatus by operating a button arranged on the operation panel 8 and selecting a function displayed on the liquid crystal display 6.

  FIG. 2 shows a block diagram of the present embodiment. Solid arrows indicate information transmission, and broken arrows indicate the direction of control. A hard disk 22, a CD drive 2, a CD-R drive 4, a PC card drive 10, a liquid crystal display 6, and an operation panel 8 are connected to the CPU 24 having a digital signal processing unit. These components are controlled by the CPU 24.

[Data structure]
As shown in FIG. 3, the hard disk 22 has an MP3 data storage area 44 and a work area 46 as information storage areas. Further, the MP3 data storage area includes a MUSIC LIST area 48 which is an area for recording a list to be described later.

  FIG. 4 shows a storage structure of audio information recorded in the MP3 data storage area 44. In this embodiment, the audio information is recorded in a hierarchical structure having a plurality of hierarchies as shown in FIG. Here, the music genre 64, the artist 66, the album 68, and the track (music) 70 are provided, but what kind of layer is configured is arbitrary.

[list]
Of the audio information recorded in the MP3 data storage area 44, which audio information is to be played back or transmitted can be easily specified by selecting a list created in advance by the user. Based on the list, detection and reproduction (or transmission) of audio information in the hard disk can be easily performed without the user sequentially instructing.

  FIG. 5 shows the structure of the list. As shown in FIG. 5, the list is in a format that holds track (music) names as identification information of audio information. However, when the purpose is to handle a large number of audio information as in the present embodiment, there is a high possibility that tracks having the same name exist even though they are different tracks. In particular, when a track name is automatically given by this apparatus, TRACK001, TRACK002. . . Etc. are used, and this possibility becomes high.

  When only the track name is held in the list and there are tracks having the same name in a plurality of different albums, the information recording control apparatus cannot specify the target track. Therefore, in this embodiment, identification information (in the example, the album name) at least one track above the track corresponding to the designated track (in the present embodiment) is also associated with the track name in the list. Record. That is, if a track is specified when creating a list, the album name is copied together with the track name of the specified track.

  Even when the album name is automatically given by the present apparatus, the same album name is not given. The same track name cannot exist in one album. Therefore, by creating the list by the above method, different tracks are not registered by the same combination of identification information. That is, the list can always identify a specific track.

  Furthermore, when searching for a track, the search time is shortened because the album search is performed first, rather than the track search directly. That is, before searching for data in the lowest layer of the hierarchical structure (ie, before searching for a track), search for the hierarchy one level above (ie, search for an album), and search the folder (album The search time is shortened by searching for the target data (ie, track) from among the above.

  The list created here is recorded in the MUSIC LIST area 48 in the MP3 data storage area 44 in the hard disk 22.

  In addition, if writing is performed on a CD-R one track at a time (track at once), a small number of tracks (session at once), or packet by packet (packet writing), between the writing areas A connecting region is generated. This connection area is a useless space from the viewpoint of storage capacity. Furthermore, due to the presence of this connection area, information recorded on the created CD-R may not be recognized as audio information by a normal CD player and may not be reproduced. In the present embodiment, the audio information in the hard disk is collectively transmitted to the CD-R based on the list (disc-at-once). It can be played back on other CD players.

  When creating the list, as shown in FIG. 6, the track name, which is the identification information of the audio information, and the identification information of at least one hierarchy (in this embodiment, the album which is the hierarchy above) May be registered in the list. By using this method, the same track name does not exist in the list, the order of the tracks in the list can be arbitrarily specified, and the order of track reproduction, transmission, or recording is arbitrarily determined. Will be able to.

  In addition, the list is not limited to registering the identification information of the audio information and the identification information of at least one level higher, and the tracks selected from the same album are in the same level in the list. May be recorded inside. Thereby, even if a plurality of tracks from the same album are selected for the same list, it is possible to avoid duplicating the name of the same album in the list. That is, when a track (music) is selected and the layer one level above this track is already registered in the list, the track selected this time is forcibly already registered regardless of the selection order. Associated with the next higher hierarchy.

[Edit mode]
FIG. 34 shows a flowchart of the list creation procedure. List creation is done in edit mode. When the MUSIC LIST is selected to create a list from the edit content selection menu 450 which is a menu for selecting the edit content shown in FIG. 35, it is recorded on the hard disk as shown in FIG. A menu for selecting the music genre of the track to be registered in the list from the music genres is displayed.

  In FIG. 36, a music genre selection menu 454 is displayed. Since the menu screen in the subsequent list creation is substantially the same as the menu screen in the playback mode, illustration is omitted, but the music genre is selected in step 404, the artist is selected in step 406, the album is selected in step 408, and the track is selected in step 410 select.

  In step 412, it is determined whether or not to register the selected track in the list. If a predetermined button on the operation panel 8 is pressed by the user and it is determined to be registered in the list, it is registered in the list in step 414, and the process proceeds to step 416.

  In step 416, it is determined whether or not the creation of the list is finished. If a predetermined button on the operation panel 8 is pressed by the user and it is determined not to end the creation of the list, the process returns to step 404. Similarly, when another predetermined button on the operation panel 8 is pressed by the user and it is determined in step 416 that the creation of the list is finished, the creation of the list is finished.

  Here, the created list is recorded in the MUSIC LIST area 48 in the MP3 data storage area 44 in the hard disk 22. As described above, the identification information held in the list includes the identification information (track name) for identifying the track shown in FIG. 5 and the identification information (album name) for identifying the layer above the track corresponding to the track. Is associated. The identification information held in the list may be in the form of a combination of the track name and album name shown in FIG. 6, or may be in the form of forming a hierarchy with the track name and album name shown in FIG. Further, one identification information may be formed by the album name and the track name. Also, the physical track search efficiency can be achieved by using a combination of two types of lists: a list in which track names and album names are combined, and a list in which track names and album names form a hierarchy. The track order for reproduction and recording can be specified.

  37 and 38 show a structure in which the track name is associated with the name of the upper layer (album) corresponding to the track, and the track name and the name of the upper layer (album) corresponding to the track form a layer. Shows the list creation process. When a track of a different album is selected at the time of creating the list, as shown in FIG. 37, the track name and the album name corresponding to the track are registered in the list as track identification information. On the other hand, when another track in the already registered album is newly designated, as shown in FIG. 38, the track name is associated with the album name as in the previously registered track in the same album. Registered.

  That is, when the MUSIC4 506 belonging to the ALBUM1 502 is newly designated, the MUSIC4 506 is associated with the already registered ALBUM1 502 and registered in the lower layer of the ALBUM1 502 in the same manner as the already registered MUSIC1 504. Is done.

  The names of music genres, artists, albums and tracks in the hard disk displayed on the menu screen must be registered in advance. If the names of the music genre, artist, album, and track are not registered by the user, they are automatically added by this apparatus.

  When registered by the user, the names of music genres, artists, albums and tracks can be registered using the liquid crystal display 6 and the operation panel 8 in the edit mode. Similarly, the name can be changed.

  The hierarchical structure in the hard disk for recording tracks can also be created by the user by selecting a hierarchy and creating and deleting folders in the edit mode. It is also possible to delete the recorded track.

  That is, folder creation, folder / track name change, folder / track deletion, and the like described above are reflected in the configuration of the MP3 data storage area 44 in the hard disk 22.
