Information storage area MSCDB for recording, and an audio information recording area RPDB for recording audio information, and record and reproduce each information in accordance with an instruction from the control unit 16.

The identification information storage area CNTDB stores identification information for identifying audio information such as music distributed in the world, and a history information storage area MSCDB.
Stores history information associated with recorded audio information already recorded in the audio information recording area RPDB.

More specifically, the identification information is not, for example, audio information recorded on a CD or DVD generally sold at a record shop or the like, or audio information distributed via a communication network itself. This is so-called catalog information edited to introduce the audio information distributed by the above-mentioned sales and distribution.

This so-called catalog information includes at least
It includes work identification information that certifies the contents of audio information for each work, and supplementary information such as song names and artist names related to the audio information. It is distributed to general users by being sold at bookstores or by distributing so-called catalog information through a communication network.

Further, as the work identification information, for example, the Japanese Society for Music Copyright (Japanese Society for Rights)
of Authors, Composers, and Publishers: JASRA
This is information that can be managed and identified, such as a work code issued by C) or a work code common to the world (ISWC).

Then, a user or the like obtains the distributed CD or DVD and reproduces the CD or DVD on the CD / DVD drive 12, thereby installing so-called catalog information as identification information in the identification information storage area CNTDB, or using the Internet or the like. By receiving the so-called catalog information distributed through the communication network of the communication device at the communication device connection unit 15 and downloading it to the identification information storage area CNTDB as identification information, the identification information is stored in the identification information storage area CNTDB in advance. ing.

As a result, as shown in FIG. 4A, in the identification information storage area CNTDB, work identification information and additional information (title name, Identification information including an artist name) is stored separately for each of the storage order and the date of storage, whereby the identification information storage area CNTDB is constructed as a database of identification information.

In the history information storage area MSCDB, FIG.
As shown in (2), each piece of history information is stored in association with individual audio information already recorded in the audio information recording area RPDB (hereinafter, referred to as “recorded audio information”).

Here, the control section 16 generates history information as follows and stores the history information in the history information storage area MSCDB. The function thereof will be described with reference to FIG.

When recording new audio information not yet recorded in the audio information recording area RPDB in the audio information recording area RPDB, the control unit 16 generates history information and stores it in the history information storage area MSCDB. Has become.

First, the control unit 16 obtains the unique information recorded on the optical disk together with the new audio information, and judges the contents of the unique information. Here, it is determined whether the piece of work identification information for certifying the content of the audio information for each piece of work or the additional information such as a song name or an artist name related to the audio information has been acquired as the unique information.

When it is determined that at least one of the work identification information and the supplementary information has been obtained, it is checked whether identification information having the same content as the work identification information or the supplementary information is stored in the identification information storage area CNTDB. .

That is, as described above, since the identification information storage area CNTDB stores the identification information having at least the work identification information and the additional information, the unique information is only the work identification information, and the additional information is included. If it is not included, the identification information having the same work identification information as the work identification information of the unique information is collated, and the unique information is only supplementary information, and the work identification information is not included. In this case, the identification information having the same additional information as the additional information of the unique information is collated. If the unique information includes the work identification information and the additional information, the work identification information and the additional information are used. The identification information having the same content as at least one of the above is collated.

Then, the identification information determined to have the same content as the unique information is acquired from the identification information storage area CNTDB by the above-described collation processing, and the acquired identification information is newly recorded in the audio information recording area RPDB. History information storage area MSCDB as history information corresponding to audio information
To be stored.

For example, as illustrated in FIG. 3, as a result of the above-mentioned comparison, the identification information storage area CNTDB corresponding to the unique information is obtained.
When the identification information (C9) is obtained, the identification information (C9)
9) is set as the latest history information (Mn), and is associated with the newly recorded audio information (Rn) in the audio information recording area RPDB, and the history information storage area MSCDB
To be stored.

When the identification information corresponding to the unique information is not stored in the identification information storage area CNTDB, instead of generating the latest history information (Mn) from the identification information, the unique information acquired from the optical disk is used. Information as the latest history information (Mn) and an audio information recording area RPD
B is associated with the newly recorded audio information (Rn) and stored in the history information storage area MSCDB.

Then, when new audio information is sequentially recorded in the audio information recording area RPDB, the recorded audio information becomes the above-mentioned recorded audio information, and the recorded audio information corresponds to the recorded audio information. History information is stored in the history information storage area MSCDB.

Although the details will be described later in the description of the operation, the audio information reproduced from the optical disk (hereinafter, referred to as “recording audio information”) is the same as the recorded audio information already recorded in the audio information recording area RPDB. If the audio information is the same, the recording is interrupted before the recording audio information is recorded in the audio information recording area RPDB, and the processing is performed according to the instruction of the user or the like. The control unit 16 determines whether or not the recording audio information is the same as the recorded audio information. At this time, the control unit 16 includes information having the same content as the unique information attached to the recording audio information. A comparison search is performed to determine whether history information to be stored is already stored in the history information storage unit MSCDB, and if history information having information having the same content is searched, recording audio information for recording is recorded in the audio information recording area RPDB. Prior to the start, the recording process is interrupted, and the process according to the instruction of the user or the like is performed.

Further, when desired history information is designated by a user or the like, the control unit 16 sets the identification information storage area CNTD
Instead of generating history information from the identification information stored in B, history information specified by a user or the like is stored in the history information storage unit MSCDB.

A decoding unit or encoding unit in the signal processing unit 18 encodes the recording audio information by another compression method or compression ratio, and records the encoded recording audio information in the audio information recording area RPDB. If you do
The control unit 16 stores information on the compression method and compression ratio of the encoded recording audio information as recording condition information in the history information storage area MSCDB in association with the history information.

As a result, as shown in FIG. 4B, the history information storage area MSCDB is associated with each piece of history information in addition to the history information generated from the above-described unique information and identification information. Recording condition information is also stored, and the history information and the recording condition information associated with each other are stored in association with the recorded audio information already recorded in the audio information recording area RPDB. .

Next, the operation of the information recording apparatus 1 having such a configuration will be described with reference to the flowchart of FIG.
Note that, as a typical case, a description will be given of a ripping edit operation in a case where audio information is reproduced from an optical disk (CD or DVD) loaded in the CD / DVD drive 12 and recorded on the hard disk 13.

In the flowchart shown in FIG. 5, when the user or the like inserts an optical disk into the CD / DVD drive 12 and operates the operation unit 21 to give an instruction to start ripping editing, the control unit 16 issues the instruction. The CD / DVD drive 12 is activated according to the following.

First, in step S100, CD /
The DVD drive 12 reproduces the unique information recorded on the optical disc, and the control unit 16 acquires the unique information.
For example, in the case of a CD, TOC (Table of Contents) information recorded in the lead-in area is acquired, and unique information such as work identification information and additional information included in the attribute information is acquired. . Also, in the case of a DVD, unique information such as work identification information and supplementary information recorded to identify the DVD is acquired.

Next, in step S102, the control unit 16 compares the unique information acquired from the optical disc with the history information stored in the history information storage area MSCDB.
A search is made for the presence or absence of history information having the same information as the unique information.

That is, as shown in FIG. 3, prior to recording the audio information recorded on the optical disk, first, the recording audio information (ie,
The unique information related to the recording audio information) and the history information are compared and searched.

As an example, if the history information having the same information (work discrimination information or supplementary information) as the unique information is the history information (M1) in FIG. 3, the same recording as the recording audio information is performed. Audio information (R1)
Is already recorded in the audio information recording area RPDB.

Thus, the comparison between the unique information and the history information
As a result of the search, when it is determined that the same recorded audio information as the recording audio information exists (“YES”)
), The process proceeds to step S106. On the other hand, if it is determined that the same recorded audio information as the recording audio information does not exist (“NO”), the process proceeds to step S1.
Move to 04.

In step S104, the recording process of the recording audio information is continued, and as shown in FIG.
The compression method set in the recording audio information is displayed on the display unit 4, and further, the user or the like is instructed whether or not the recording audio information is encoded by another compression method or a compression ratio and recorded. Menu display for

FIG. 6A shows the first item,
An indication that the recording audio information is recorded in "CD-DA (CD format)" is displayed, a display indicating that a compression method and a compression ratio should be set is made in a blank section of the second item, and a third information is displayed. Shows a case where a display for prompting an instruction to start recording is made in the item of.

When the user or the like inputs a desired compression method or compression ratio, or a compression method and a compression ratio from the operation unit 21 in accordance with the above menu display, and gives a recording start instruction, the control unit 16 is instructed. Then, the process proceeds to step 116.

If the user or the like gives an instruction to start recording without inputting a compression method and a compression ratio, the process also proceeds to step 116.

The processing is performed from step 104 to step 116.
Then, at step 116, step S1 is performed.
In step 04, the decoding condition and the encoding portion instructed by the user or the like are instructed to the decoding portion and the encoding portion in the signal processing portion 18 to start the reproduction of the recording audio information from the optical disk, and the decoding portion and the encoding portion perform the recording. For the audio information for recording, the instructed encoding is performed, and the encoded recording audio information is recorded in the audio information recording area RPDB.

As described above, step S104
In step 116, when the recording start is instructed without input of the compression method and the compression ratio from the user or the like, in step 116, the reproduction of the recording audio information from the optical disk is started, and the recording audio information is recorded. The recording is directly recorded in the audio information recording area RPDB without changing the encoding condition.

As described above, the recording audio information can be recorded in the audio information recording area RPDB by the encoding method desired by the user or the like, and the convenience and versatility are improved.

For example, rather than recording audio information for recording in the audio information recording area RPDB as it is, the compression method and the compression ratio are appropriately changed so that the audio information recording area RPDB can be used more effectively and more audio data can be recorded. Information can be recorded.

Next, when the process proceeds to step S106 as a result of searching for the history information having the same information as the unique information in the above step S102, the display unit 4 is instructed to record the audio information for recording. An indication that the same recorded audio information is present is displayed, and the comparison / searched history information and the recording condition information stored in association with the history information are displayed. Further, a menu is displayed for prompting a user or the like to determine whether or not the recording audio information should be recorded. FIG. 6 as an example
The display as shown in (b) is performed.

Next, in step S108, it is determined whether an instruction of "stop recording" has been given by the user or the like to the above menu display, and in the case of "stop recording"("YE
In the case of "S"), the process ends without recording the recording audio information.

On the other hand, when the instruction of “continue recording” is given (in the case of “NO”), the process shifts to step S110.

In step S110, a menu is displayed for prompting the user or the like to instruct whether or not the recording audio information should be encoded by a desired compression method or compression ratio and recorded. For example, a menu is displayed as shown in FIG.

Then, upon input of a desired encoding condition (compression method or compression ratio) from the user or the like in accordance with the menu display and an instruction to complete the setting is made, the flow shifts to step S112.

In step S112, it is determined whether or not the encoding condition input from the user or the like is the same as the recording condition information of the recorded audio information described above. Here, if it is determined that the input encoding condition and the recording condition information are the same (in the case of “YES”), the process proceeds to step S114,
If the encoding condition and the recording condition information are different (“N
In the case of "O"), the process proceeds to step S116.

In step S116, a menu is displayed on the display unit 4 as shown in FIG. 6D to urge an instruction as to whether or not to stop recording. In addition, the input encoding condition is displayed, and a display that the input encoding condition and the recording condition information are the same is displayed.

Here, it is determined whether or not the user has instructed “stop recording” with respect to the menu display, and if the “stop recording” instruction has been given (in the case of “YES”),
The process ends without recording the recording audio information.

On the other hand, when the instruction of “recording start” is given (in the case of “NO”), after the above-mentioned temporary suspension is released, the processing shifts to step S116.

As described above, steps S106 to S114
Is provided to interrupt the recording process when the same recorded audio information as the recording audio information has already been recorded, and to prompt the user or the like to select whether to stop recording or to perform recording.

That is, in step S108, the user or the like can select whether to "stop recording" or to change the encoding condition and perform recording, and determine that the encoding condition should be changed and recorded. In this case, the recording process is restarted, and in step S110, a desired encoding condition can be designated. If the specified encoding condition is new to the recording condition information of the recorded audio information, the process proceeds to step S112 through step S112.
The process can be shifted to a recording step of 116,
On the other hand, if the specified encoding condition is the same as the recording condition information of the recorded audio information as a result of, for example, erroneous input, in step S114,
The user can select whether to “stop recording” or perform recording. Then, when "recording start" is selected, the recording process is restarted even if the designated encoding condition is the same as the recording information of the recorded audio information, and step S116 is performed.
The process can be shifted to the recording step.

As described above, the convenience is improved by providing the user and the like with various methods of handling the recording audio information.

Next, when the process shifts from step S112 to step S116, in step S116, the encoding condition instructed by the user or the like is instructed to the decoding unit and the encoding unit in the signal processing unit 18, and While starting the reproduction of the recording audio information from the, the decoding unit and the encoding unit, for the recording audio information, performs encoding under the specified encoding conditions,
The encoded recording audio information is recorded in the audio information recording area RPDB.

When the process shifts from step S114 to step S116, the recording audio information is overwritten on the already recorded audio information in step S116. As a result, it is possible to obtain effects such as updating old recorded audio information with new recording audio information.

As described above, the audio information recording area RPDB
In addition, even when the same recorded audio information as the recording audio information has already been recorded, the recording audio information can be recorded, thereby improving the convenience and versatility. For example, when the user or the like instructs to change the compression method or the compression ratio and record, the recording audio information can be recorded as new audio information, and further, the recorded audio information can be recorded more than already recorded audio information. An effect such as high-quality recording can be obtained.

Next, when the recording processing in step 116 is completed, the flow shifts to step 118, where the history information storage area MS
Start the process for storing history information in the CDB.

First, in step 118, as shown in FIG. 6 (e), it is determined whether to automatically generate and store history information or to store desired history information such as a user. Display for prompting. If the user or the like makes a selection for automatically generating history information (in the case of “YES”), the process proceeds to step 120 and if so-called manual creation for creating desired history information is selected (“NO”). "), The process proceeds to step 122.

In step 120, the above-described step S1
04 to step S116 (hereinafter, referred to as “first case”), and when the process proceeds from step S112 to step S116 (hereinafter, “second case”).
In the case of “)” and steps S111 to S
When the processing has shifted to 116 (hereinafter, referred to as “third case”), specific processing is performed.

When the recording corresponding to the above “first case” is performed, as shown in FIG. 3, the identification having the same information as the unique information accompanying the recording audio information is performed. Check the information. Then, the identification information obtained as a result of the collation is used as history information, and the history information is associated with newly recorded audio information (audio information that has become recorded audio information by recording recording information). Store in the history information storage area MSCDB.

Further, as described above, when a user or the like instructs to set an encoding condition (a compression method or a compression ratio), the encoding condition is set as recording condition information and associated with the history information. When the user or the like instructs not to set the encoding condition, the encoding condition of the recording audio information is stored as it is as recording condition information in association with the history information.

When the recording is performed roughly in the above-mentioned "second case", as shown in FIG. 3, information having the same content as the unique information accompanying the recording audio information is provided. Check the identification information. Then, the identification information obtained as a result of the collation is used as history information, and the history information corresponds to newly recorded audio information (audio information that has become recorded audio information as a result of recording audio information for recording). And store it in the history information storage area MSCDB.

Further, as described above, the encoding condition (compression method and compression ratio) for which the setting instruction is given by the user or the like is stored as the recording condition information and associated with the history information.

When the recording corresponding to the above “third case” is performed, that is, when the above-described overwrite recording is performed, the history information and the recording condition information are not stored, and the information already exists. The history information and the recording condition information are stored as they are.

When the storage of the history information is completed, the process ends.

Next, when the process proceeds from step 118 to step 122,
The display illustrated in FIG. 6F is performed to prompt the user or the like to input desired history information. Then, when the history information is input and an instruction to start storing the history information is given,
The input history information is stored in the history information storage area MSCDB in association with newly recorded audio information (audio information that has become recorded audio information by recording the recording information). Then, when the storage of the history information is completed, the process ends.

As described above, the user and the like can arbitrarily specify the history information, so that the user and the like can appropriately specify the history information that is easy to manage and can specify the history information that suits the user and the like. Such effects as possible can be obtained, and convenience and versatility are improved.

As described above, according to the present embodiment, prior to recording the audio information recorded on the optical disk on the hard disk as the storage medium, the unique identification information having the work identification information or the supplementary information is used. Since the work identification information and the history information having the supplementary information are compared, it can be more accurately determined whether or not the same audio information as the audio information to be recorded has already been recorded on the hard disk. Rip editing can be performed. In particular, using work identification information to identify audio information as a criterion,
Since it is determined whether or not the same audio information as the audio information to be recorded has already been recorded on the hard disk, an accurate determination can be made.

Furthermore, since the same is not checked for the data constituting the audio information to be recorded and the data constituting the already-recorded audio information as in the prior art, Editing processing time can be reduced.

Incidentally, as a typical case, a CD or DVD
The case where audio information reproduced from a hard disk is recorded on a hard disk has been described. However, audio sources supplied from other sources such as a memory card, an information terminal device, a digital television broadcast receiving tuner, and an external information recording device, etc. It is possible to rip and edit information.

That is, when recording the audio information stored in the memory card inserted into the external storage medium slot 14 shown in FIG. When recording audio information distributed to a television broadcast receiving tuner on a hard disk, or when inputting audio information supplied from an external information recording device to the optical input unit 22 or A
Even when the data is input via the / D converter 23 and recorded on the hard disk, ripping editing can be performed.

In such a case, unlike the case of an optical disk such as a CD or a DVD, it is often impossible to acquire information of a unique identification code. However, as described above, since the user or the like can manually create history information by manual operation, duplicate recording can be prohibited, and a highly versatile ripping editing function can be provided.

For example, if the user instructs to store the album title name and the artist name in the history information, an error in detecting the identity between the audio information to be recorded and the recorded audio information is detected. Detection can be prevented.

During ripping editing, audio information targeted for ripping editing may be reproduced by a speaker or the like so that a user or the like can listen.

[0111] Alternatively, information other than the audio information to be ripped and edited may be reproduced by a speaker or the like, and the ripping and editing may be performed while the user or the like listens. For example, when audio information recorded on an optical disk such as a DC / DVD is recorded on a hard disk, audio information supplied from an external information recording device, which is another information source, is output in accordance with an instruction from a user or the like. It may be reproduced and provided to the user or the like.

The history information and the identification information are stored in the history information storage area MSCDB and the identification information storage area CNTDB of the hard disk.
However, a storage unit separate from the hard disk may be provided and stored in the storage unit.

As described with reference to the flowchart of FIG. 5, after recording audio information is recorded in step 116, history information is stored in steps 118, 120 and 122. Before recording the information, the history information may be stored, and then the recording audio information may be recorded.

Also, a case has been described in which the audio information is ripped and edited, but it is possible to rip and edit video information such as a movie.

[0115]

As described above, according to the information recording apparatus of the present invention, when recording a content supplied from a source source on a storage medium, the unique information of the content and the history stored in the history information storage means are stored. If the history information containing the same information as the unique information is already stored in the history information storage means, the recording of the content supplied from the source source to the storage medium is interrupted. Therefore, it is possible to avoid duplicating recording of the same content as content already recorded.
