DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an information recording control device, and more particularly, to an information recording control device for reproducing information recorded on a recording medium.

[0002]

2. Description of the Related Art
The 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. Playback,
It was easy enough to manually select the songs to record.

However, when a storage device having a larger storage capacity than a conventional CD-DA is inexpensive, and the technique of compressing information is applied, the number of information that can be stored on a single storage medium may increase dramatically. Conceivable. If the information is audio information, it is possible to store several thousand audio information in a single storage device. It is very difficult to manually select audio information to be reproduced and recorded from several thousand audio information.

[0004] The present invention has been made in view of the above-described circumstances, and has as its object to provide an information recording control device capable of efficiently recording and reproducing a large amount of information recorded on a recording medium.

[0005]

In order to achieve the above object, an information recording control device according to claim 1 is capable of recording a plurality of audio information in a plurality of hierarchical structures and identifying the audio information. A recording medium having an information storage area capable of recording first identification information and second identification information for identifying at least one higher layer corresponding to the audio information, and selecting means for selecting at least one of the audio information And at least one of the first identification information for identifying the audio information selected by the selection means and the second identification information for identifying at least one layer above the audio information, An information recording control device, comprising: a list that identifies at least one level higher than the hierarchy associated with the audio information selected by the selection unit. Information and the second identification information for identifying at least one layer higher than the other audio information already held in the list, are equal to each other. It is characterized in that the first identification information is held in association with the second identification information for identifying at least one higher layer associated with the other audio information.

[0006] The recording medium is capable of recording a plurality of pieces of audio information in a plurality of hierarchical structures, and a first medium for identifying the audio information.
And an information storage area capable of recording second identification information for identifying at least one higher layer corresponding to the audio information. The selection means selects at least one of the audio information. The list includes the first identification information for identifying the audio information selected by the selection unit,
The audio information is held in association with the second identification information for identifying at least one layer above the audio information.

[0007] The list may be stored in the information storage area.

[0008] When the audio information is output, the second identification information for identifying the at least one layer above the audio information including the audio information may be output together.

As described above, since a list in which identification information of audio information is recorded is used to search for a large number of audio information recorded on a recording medium, audio information can be recorded and reproduced efficiently.

[0010] Even when tracks having the same name exist in different albums, the list can specify the tracks. Further, the tracks existing in the same album on the recording medium are also present in the same album in the list, so that the audio information can be searched efficiently.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings. [Hardware Configuration] FIG. 1 shows an external appearance of the information recording control device according to the present embodiment from the front. This information recording control device includes a hard disk (not shown). In this embodiment, a hard disk of 8.4 GB (about 140 hours for music playback) is used. However, a hard disk having a capacity other than 8.4 GB or high-speed access equivalent to a hard disk is possible, and high-speed playback is possible. May be another digital information recording device.

This apparatus also has 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. In addition, various memory cards such as a multimedia card and a memory stick and a digital storage device that can be connected to the apparatus via the PC card drive 10 can be used. PC
In addition to the card drive, a connector for transmitting information, such as a serial cable port or an infrared port, may be provided.

Further, the present apparatus is provided with a liquid crystal display 6 serving as an interface with a user. The user can operate the present apparatus by operating buttons arranged on the operation panel 8 and selecting functions displayed on the liquid crystal display 6.

FIG. 2 shows a block diagram of the present embodiment. Solid arrows indicate the transmission of information, and dashed arrows indicate the direction of control. CP having digital signal processing unit
U24 has a hard disk 22, a CD drive 2, a C
The DR drive 4, PC card drive 10, liquid crystal display 6, and operation panel 8 are connected. These components are controlled by the CPU 24. [Data Structure] As shown in FIG.
Has an MP3 data storage area 44 and a work area 46 as information storage areas. Further, the MP3 data storage area is an area for recording a list to be described later.
IST region 48 is included.

FIG. 4 shows a storage structure of audio information recorded in the MP3 data storage area 44. In the present embodiment, audio information is recorded in a hierarchical structure having a plurality of layers as shown in FIG. Here, music genre 64, artist 66, album 68, track (music) 70
, But what kind of hierarchy is configured is arbitrary. [List] Of the audio information recorded in the MP3 data storage area 44, which audio information to reproduce or transmit can be easily specified by selecting a list created in advance by the user. It is. Based on the list, detection and reproduction (or transmission) of audio information in the hard disk can be easily performed without sequentially instructing the user.

FIG. 5 shows the structure of the list. As shown in FIG. 5, the list is in a format holding track (music) names as identification information of audio information. However,
When the purpose is to handle a large number of pieces 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, if the track name is automatically assigned by the device, the TRA
CK001, TRACK002. . . This is more likely to be used.

If only a track name is held in the list and a track having the same name exists in a plurality of different albums, the information recording control device cannot specify the target track. Therefore, in the present embodiment, the identification information (album name in the example) of at least one level above (in this embodiment, one level above) the track corresponding to the designated track is also associated with the track name and is listed. Record. That is, if you specify a track when creating a list,
The album name is also copied together with the track name of the designated track.

Even when the album name is automatically given by the present apparatus, the same album name is not given. Also, 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 particular track.

Further, when searching for a track, instead of directly searching for a track, first, an album search is performed, so that the search time is reduced. That is, before searching for data at the lowest layer of the hierarchical structure (that is, before searching for a track), a search for a layer one level higher than that (that is, searching for an album) is performed, and the searched folder (album) is searched. ), The search time is reduced by searching for the target data (ie, track).

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

When data is written on a CD-R one track at a time (track at once), a small number of tracks at a time (session at once), or packet by packet (packet writing), writing is performed. A connection area is created between the areas. This connection area is a useless space from the viewpoint of storage capacity. Further, due to the presence of the connection area, information recorded on the created CD-R is not recognized as audio information by a normal CD player,
Playback may not be possible. In the present embodiment, the audio information in the hard disk is collectively transmitted to the CD-R on the basis of the list (disk-at-once), so that this connection area does not occur, and the created CD-R is normally read. Can be played back on a CD player.

When a list is created, tracks selected from the same album are recorded in the same hierarchy in the list. As a result, even if a plurality of tracks are selected from the same album for the same list, it is possible to avoid duplication of the same album name in the list. That is, if a track (music) is selected and the next higher level of this track is already registered in the list, the track selected this time is forcibly registered regardless of the selection order. Associated with the next higher level.

Also, the list is not limited to the case where the tracks selected from the same album are recorded in the same layer in the list, but is identification information of audio information as shown in FIG. A track name and identification information of at least one higher layer (in this embodiment, the name of an album that is one layer higher) may be registered in a 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 reproduction, transmission, or recording of the tracks can be arbitrarily determined. Will be able to do it.
