2. Description of the Related Art Recently, music data, game programs,
Various software data such as image data (hereinafter, these are referred to as contents), networks such as the Internet, memory cards, HD,
Distribution through a distributable storage medium such as a DVD or a CD has become popular. These distributed contents are stored in a user-owned PC (Personal Computer), recording / playback device, playback-only device, or game device, such as H.
D, card type storage device having flash memory, C
It is stored in the D, DVD, etc., and the reproduction process is executed.

Information devices such as recording / reproducing devices, game machines, and PCs have interfaces for receiving contents from a network, or memory cards, HDs, DVs.
RAM, RO having an interface for accessing D, CD, etc. and used as a memory area for control means, programs, and data required for reproducing contents
M and so on.

Various contents such as music data, image data, programs, and the like are transmitted from a recording / reproducing device used as a reproducing device, a game device, a user instruction from an information device main body such as a PC, or a connected input means. In response to the user's instruction, for example, it is called from a built-in or removable storage medium, and reproduced through the information equipment main body or a connected display, speaker or the like.

Many software contents such as game programs, music data, image data, etc. are generally owned by their creators and sellers. Therefore, when distributing these contents, certain usage restrictions, that is, only authorized users are permitted to use the software and unauthorized copying is not performed, that is, security is considered It is common to adopt the above configuration.

Particularly, in recent years, recording devices and storage media for digitally recording information have become widespread. According to such a digital recording device and storage medium, recording and reproduction can be repeated without deteriorating images and sounds, for example. In this way, since digital data can be repeatedly copied many times while maintaining image quality and sound quality, when a illegally copied storage medium comes into the market, various contents such as music, movies, etc. The profits of the copyright holders or legitimate sales right holders will be harmed. In recent years, in order to prevent such illegal copying of digital data, various processing configurations for preventing illegal copying have been realized or proposed in a digital recording device and a storage medium.

[0007] For example, SDMI (Secure Digital music Initiation) has proposed various specifications in music distribution technology.
has proposed a standard for a copyright protection function in a portable player. There are various forms of implementing the copyright protection function, such as the limitation on the number of copies of the content and the limitation on the usage period of the content.

[0008]

A flash memory, H
In a system that records and reproduces contents such as audio data and video data using a memory card using D or the like as a storage medium, contents such as music are copied from the storage medium such as a CD to the memory card, and the memory card is mounted. There is a usage mode such as enjoying with a portable playback device. In addition, the content distributed from the network is temporarily stored in a large-capacity storage medium such as a hard disk built in the personal computer, and then the content is moved from the personal computer to a memory card or a portable small hard disk (HD), A form in which a content is reproduced by a portable device in which a memory card and a HD can be mounted, that is, a form in which a PC is used as a personal server for the contents is becoming popular.

Contents from a storage medium such as a CD or contents obtained through communication such as the Internet are temporarily stored in a hard disk, and the contents are copied or moved from the hard disk to a memory card. Then, there is a problem in copyright of the content that the content is randomly used such that the content is reproduced on the memory card side. The move, that is, the movement of the content is an operation mode realized by, for example, copying and recording the content from the HD to the memory card and then erasing the content from the storage medium (HD) that is the copy source.

From the viewpoint of copyright protection, it is necessary to restrict copying and moving to some extent. On the other hand, completely prohibiting copy / move is not appropriate because it hinders the use of contents such as moving the contents from the PC to the portable media and enjoying the reproduction of the contents outside as described above. . Therefore, it is required to realize appropriate copy / move management so that the copyright protection can be realized and the user's right to private copy can be maintained.

In view of the above problems, a configuration has been proposed in which a number of times is set for content transfer processing from a PC to a portable device, and the number of content transfers is counted on the PC side. In a configuration that executes such counting processing, whether the content that has been transferred to the portable device remains in the portable device or is erased in order to reliably verify the number of times of content transfer or to eliminate duplicate transfer of content. There is a case where a process for determining the above is performed.

In such a search process, if the portable medium has a small capacity, the number of stored contents is small and it does not take time to judge the presence / absence of contents to be searched. Portable media with high capacity storage media have become available. The number of contents that can be transferred from a PC to a portable medium having such a large-capacity storage medium is, for example, more than 10,000 songs for music. The search processing from such a large amount of content requires a lot of time, resulting in inefficiency of the processing.

The present invention has been made in view of the above circumstances, and realizes appropriate content management regarding copying / moving between devices, and particularly in a content transfer processing configuration in a large-capacity portable medium, it is efficient. It is an object of the present invention to provide an information recording processing device, a content input / output management device, a content management system, an information recording processing method, a content input / output management method, a content management method, and a computer program capable of performing dynamic processing.

101, RAM 103, or HDD 111.

Next, a configuration example of an information recording processing device such as a portable medium or a portable device capable of storing contents will be described with reference to FIG. The content storage medium is a flash memory, a compact HD, an optical disc, a magneto-optical disc, or the like.

The power supply circuit 152 converts the supplied power supply voltage into internal power of a predetermined voltage and supplies it to the CPU 153 to the display unit 167 to drive the entire apparatus. The input / output I / F 157 is an interface that connects to a personal computer (PC) 172 that is a content providing source, and makes a connection in a connection mode such as USB or IEEE1394.

The data transferred from the personal computer 172 is composed of data of 64 bytes per packet as an example, and is transferred from the personal computer to the portable device at a transfer rate of 12 Mbit / sec. The data transferred to the portable device is made up of content and incidental information such as usage conditions of the content.

When the portable device receives a content write command from the personal computer together with the content, the CPU 153 which executes the main program read from the ROM 155 to the RAM 154 receives the write command and receives the write command from the storage medium 161, for example, a flash memory, HD, or the like. Content writing is executed on DVD and CD. In the example of the drawing, a flash memory, HD, DVD, and CD are shown as the storage medium 161, but these storage media are examples, and at least one type of storage medium can be used.

The process of writing data to the storage medium 161 is executed via the storage medium controller or drive 160 corresponding to the storage medium 161. For example, if the storage medium 161 is a flash memory, writing is executed via the flash memory controller, and if the storage medium 161 is a hard disk (HD), writing is executed via an HDD. The storage medium 161,
For example, flash memory, HD, DVD, and CD can be configured as removable devices in a portable device.

When a content reproduction command from the user is supplied to the CPU 153 via the operation key controller 162, the CPU 153 causes the storage medium controller or the drive 160 to execute a content read process from the storage medium 161, and transfers it to the DSP 159.

DSP (Digital Signal Processor) 159
Executes a reproduction process of the content transferred from the storage medium 161. The DSP 159 has an encryption / decryption processing function, an equalizer adjustment (gain adjustment corresponding to the frequency band of an audio signal) function, compression / expansion (encoding / decoding).
It has a processing function. For example, high-efficiency encoding is performed to write a digital audio signal in the storage medium 161, and data read from the memory card 161 is decoded. As a high-efficiency coding method, ATRAC (Adaptive Transform Acoustic C
A modified version of ATRAC3 is used.

In ATRAC3, sampling frequency =
Audio data having 16-bit quantized bits sampled at 44.1 kHz is subjected to high efficiency encoding processing. AT
The smallest data unit when processing audio data in the RAC3 is the sound unit SU. 1 SU is 10
It is obtained by compressing 24 samples (1024 × 16 bits × 2 channels) into several hundred bytes, and the time is about 23 msec. Approximately 1 / though the above high-efficiency coding processing
Audio data is compressed to 10.

The digital-analog conversion circuit 163 converts the reproduced content into an analog audio signal and supplies it to the amplification circuit 164. The amplifier circuit 164 amplifies the audio signal and supplies the audio signal to a headphone (not shown) via the headphone jack 165.

From the input I / F 171, a digital signal or an analog signal is input from an external source, and A / D conversion is performed when the analog signal is input. In the A / D conversion, the input signal to be input is, for example, sampling frequency = 44.1.
Convert to a digital audio signal of kHz and quantization bit = 16 bits. Further, a digital signal from an external source is similarly converted into a digital audio signal having a sampling frequency of 44.1 kHz and quantization bits of 16 bits by an SRC (sampling rate converter).

Further, the CPU 153 controls the LCD controller 166 to display on the display unit 167 the state of the reproduction mode (eg, repeat reproduction, intro reproduction, etc.), equalizer adjustment (gain adjustment corresponding to the frequency band of the audio signal). ), Song number, playing time, playback, stop, fast-forward, fast-reverse status, volume, and battery level information.

For the content encryption / decryption processing executed by the DSP 159, for example, DES (Data Encryption) is used.
Standard) encryption algorithm is applied. The content encryption is a process for protecting the copyright of the content, and the content encryption process is executed in the content transfer process between the PC and the portable device and the content transfer process between the portable device and the storage medium. .

For example, an EEPR including a flash memory
The OM 168 stores a plurality of master keys and a unique storage key for each device, and performs content transfer processing between the PC and the portable device, authentication processing and session key sharing processing in the content transfer processing between the portable device and the storage medium. , Transfer data,
Alternatively, a master key and a storage key are applied in encryption and decryption processing of stored data.

The portable device of this embodiment is an EEP.
The ROM 168 further stores a plurality of different device IDs. These are IDs that are applied during the content input / output processing executed with the PC, that is, the check-in / check-out processing. The check-in / check-out process using this device ID will be described in detail below.

[Check-in / Check-out Processing] Next, regarding the input / output processing of the content, that is, the check-in / check-out processing, which is executed between the personal computer and the information recording processing device having the storage medium capable of storing the content. explain.

The check-in / check-out process is executed by the check-in / check-out management program stored in the personal computer. The check-in / check-out management program is a portable information recording processing device for contents stored in a storage medium such as a hard disk of a PC based on check-in or check-out settings and usage condition data corresponding to the contents. Performs control and management in the process of outputting (checking out) to a portable device equipped with a media or a portable media,
In addition, if the content stored in the information recording processing device is P
It is a program that executes control and management of check-in processing that is returned to C.

The check-in / check-out management program updates the counter as the number of check-outs set corresponding to the content as the usage condition data corresponding to the content in response to the check-in or check-out processing. .

FIG. 4 is a diagram showing an example of the check-in / check-out operation instruction window displayed on the display of the PC during the check-in / check-out processing.

Check in / display on the PC display.
An album title, a song title, an artist name, etc. are displayed as the content-related data to be checked out. The field [No. ], The identification number corresponding to the title is displayed, and the number of possible checkouts at the present time is displayed in a distinguishable manner as a note.

Items [No. ] Is the one note
This indicates that one checkout process is possible. No. [SOMEWHERE IN ...] of 1 is one note, and only one checkout, that is, P
It is the content for which the content transfer process from C to the portable device is permitted once more. No. 2 [HE
[RE AND ...] is two notes, and is content that has been checked out twice, that is, content transfer processing from the PC to the portable device has been permitted twice. No. [WE COULD ...] of 3 is note 3
This indicates that the content is currently permitted to be checked out three more times. No. No. 5, [BETTER MAKE ...], shows rest marks instead of notes, and indicates that the content is set to be incapable of further checkout processing. That is, it indicates that the permitted number of checkout processes have already been executed.

The personal computer stores the content together with the data related to the content (for example, the song title or the reproduction condition) in, for example, a USB (Universal Se).
rial bus) via a portable device connected via a cable to a portable medium attached to the portable device. At the time of this check-out processing, the usage condition counter corresponding to the stored content is updated. The counter corresponds to the number of notes shown in FIG. By executing the check-out process, the counter corresponding to the content recorded by the personal computer is decremented by one. That is, the number of possible checkouts is reduced by one. When the number of times check-out is possible is 0, the corresponding content cannot be checked out.

By thus setting the counter for counting the number of check-outs of contents from the PC as the usage condition corresponding to the contents, it is possible to prevent one content from being copied from the PC to an infinite number of storage media. You can For example, when the maximum number of checkouts is 3, the counter corresponding to the content stored in the HD of the PC is set to 3. This setting allows copying of content from a PC to a maximum of three storage media, but prohibits further copying.

The content correspondence counter of the PC is 3 for each content transfer process from the PC to the portable medium as the information recording processing device, that is, every check-out process.
For content whose counter is updated to 2 → 1 → 0 and which has become 0, transfer (checkout) processing from the PC is prohibited.

Content checked out to a portable medium and stored in a storage device such as an HD, a flash memory, or an optical disc can be returned to the hard disk of the PC. Such a return process from the portable medium to the PC is called a check-in process.

When this check-in processing is executed, P
The counter set corresponding to the content stored in the C HD increases. That is, when the content is returned (checked in) from the portable media that checked out the content, the personal computer increments the counter and updates the content correspondence counter of the PC with 0 → 1 → 2 → 3 every check-in. To do. Therefore, it is possible to repeatedly check out according to the increment of the counter.

At the time of the check-in processing, the personal computer (PC) determines whether or not the portable medium requesting the check-in processing is the portable medium checked out by itself and checked out itself. The check-in processing is executed only when the request is for the check-in processing of the content from the portable medium. That is, when the portable medium storing the content stores the content checked out from another PC, the check-in process of the content is not executed. For this identification, the personal computer (PC) acquires the device ID of the portable medium (PM) that executes the checkout at the time of the checkout process, and associates it with the checkout process content and stores it in the memory in the PC. Store.

This device ID is associated with the content and P
By storing in C, "deemed check-in processing" described below becomes possible. For example, when the contents checked out from the PC to the portable media (PM) are erased on the go, the erased portable media (PM) is transmitted to the PC via the portable device, for example.
The PC detects that the content checked out by itself is erased from the portable media (PM) by connecting to the PC, and the check-in process from the portable media (PM) is not executed yet. If confirmed, it is assumed that the check-in process has been virtually executed, and the process of incrementing the counter set for the erased content by 1 is executed. By this deemed check-in, the counter can be restored (incremented) even if the checked-out content is erased outside.

When executing such a deemed check-in process, the personal computer (PC) checks the contents checked out by the portable computer (P).
A process for determining whether or not the data has been deleted from M) will be executed. At this time, a search process for the target content identifier is executed. Portable media (P
If the capacity of M) itself is small and the number of stored contents is small, the time required for search does not matter, but if a small hard disk is used as a portable medium (PM), a large amount of content is stored in the HD. Therefore, it takes time to search for the target content from these large amounts of content.

In the system of the present invention, a hard disk,
Even if the content is checked out to a portable medium (PM) having a large storage capacity such as an optical disk, a magneto-optical disk, or a large-capacity flash memory, the PC can easily search for the target content identifier and search for the content. It has a configuration that makes it possible to determine the presence or absence.

In the system of the present invention, a plurality of device IDs are set for a portable medium as an information recording processing device having a storage element such as an HD, a flash memory, an optical disc, a magneto-optical disc, or a portable device on which the portable medium is mounted. To do. Check-in / check-out processing is executed by selectively using these device IDs. The plurality of device IDs are stored in a memory in the information recording processing device, for example, the EEPROM in FIG. For example, 500 different device IDs are set in the memory of one information recording processing device as device IDs usable by the information recording processing device. These device IDs are unique identification data stored at the time of manufacture and unique.

At the time of content check-out / check-in processing, check-out / check-in processing corresponding to one device ID selected from 500 different device IDs is executed. By selectively using such a device ID, one information recording processing device is virtually
It becomes possible to recognize the different devices from the PC.

FIG. 5 shows an execution processing flow showing details of content check-out processing for a portable device equipped with a portable medium (PM). The details of the process will be described below according to the flow.

First, for example, a portable device (ex. Portable recording / reproducing apparatus) equipped with a portable medium having a storage element such as an HD, a flash memory, an optical disc, a magneto-optical disc, etc. It connects to a computer (for example, USB connection), and executes mutual authentication processing and key exchange processing between the PC and the portable device.

This is a process for confirming the validity of each other. Examples of mutual authentication protocols that are executed include common key cryptography represented by ISO / IEC 9798-2, public key cryptography represented by ISO / IEC 9798-3, ISO / IEC The one using a cryptographic check function (MAC) typified by 9798-4 and the like can be given.

FIG. 6 shows a cryptographic check function (MAC).
One of the methods for mutual authentication and encryption key sharing using is used in this embodiment.

In FIG. 6, devices A and B corresponding to either a personal computer or a portable device, which are a content transmitting device and a content receiving device, have a configuration capable of storing or generating a common key Kab. . The personal computer of this system uses the above-mentioned master key to generate the common key Kab. The processing in FIG. 6 will be described. The device B generates a random number Rb and sends it to the device A. The symbol “||” in FIG. 6 represents a connection.

Next, the device A generates random numbers Ra and Sa, and MAC (Kab, Ra || Rb || S together with Ra and Sa.
Send a) to device B. MAC (Kab, Ra || Rb ||
Sa) uses Kab as a key for the cryptographic check function,
Indicates that Ra || Rb || Sa is input as data.
The cryptographic check function is a FIPS 46-2 Data Encryption Standard (Data Encry), as specified in ISO / IEC 9797.
ption Standard, DES).

The device B itself calculates the MAC (Kab, Ra || Rb || Sa) using the received data and checks whether this matches the received one. If they match, the device A, which is the communication partner, is recognized as valid and the processing is continued, but if they do not match, it is determined to be invalid and the processing is stopped.

Next, the device B generates a random number Sb and sends it and the MAC (Kab, Rb || Ra || Sb) to the device A. Device A also uses the received data to MAC itself
(Kab, Rb || Ra || Sb) is calculated and it is confirmed whether or not it matches the received one. If they match, the device B, which is the communication partner, is recognized as valid and the processing is continued, but if they do not match, it is determined to be invalid and the processing is stopped. Finally,
Both sides compute MAC (Kab, Sa || Sb) and use this as the session key for the session.

By the above, the personal computer and the portable device as the content transmitting device and the receiving device can inspect each other's legitimacy and can safely share the session key. After that, the transfer data between the personal computer and the portable device is encrypted with the session key if necessary.

Returning to FIG. 5, the checkout process will be further described. The result of the authentication process in step S101 is determined in step S102, and if the authentication is not established, the checkout process is not executed and the process ends. If the authentication is successful, the process proceeds to step S103, and it is verified whether or not the check-in process for the device ID included in the check-out request data received from the portable device on the PC side has been executed.

The portable device as the information recording processing device, when requesting the check-out process from the PC as the content input / output management device, makes use of the plurality of devices I described above.
The device ID selected from D (for example, 500 types) is P
Send to C. As shown in FIG. 7, the hard disk on the PC side stores a check-in / check-out management table together with the encrypted content.

The check-in / check-out management table, as shown in FIG. 7, is a content ID (C
ID is registered, and the checkout number count value (CO) corresponding to the checked-out content ID (CID) is stored. In the example shown in FIG. 7, content: CI for device ID = 1000
D = 1, 2, 3, 4 is checking out, and device I
Content for D = 1001: CID = 1, 2, 5
Indicates that the device is checking out and the content: CID = 1, 3 is checking out for the device ID = 1002. Furthermore, the checkout count value (C.O.) of CID1 is 3, and the checkout number count value of CID2 is 3 The checkout number count value (C.O.) is 2, the checkout number count value (C.O.) of CID3 is 2, the checkout number count value (C.O.) of CID4 is 1, and the checkout number of CID5 is It indicates that the number count value (C.O.) is 1.

Returning to FIG. 5, the explanation of the checkout process will be continued. In step S103, the PC sets P
The C side verifies whether the check-in process for the device ID included in the check-out request data received from the portable device has been executed. The check-in process is executed as a process of returning the checked-out content from the portable device to the PC as described above.

The PC is a portable medium (for example, H-type) in which the contents registered in its own check-in / check-out management table are attached to the portable device.
D, flash memory, optical disk, magneto-optical disk)
It is determined whether or not the check-in is performed by searching whether or not it is stored in. This process is executed as a process of searching for a content identifier from a directory generated corresponding to the stored content in the portable medium.

The directory structure corresponding to the content data stored in the storage medium of the information recording processing apparatus of the present invention, for example, HD, flash memory, optical disk, magneto-optical disk will be described with reference to FIG. As shown in the figure, a file directory for still images, a file directory for moving images, a file directory for music, and a category-specific directory are formed from the root directory. In this example, the recording / playback of music will be mainly described, so that the music directory will be described below.

In the system of the present invention, two independent directories HiFi and HiFi2 are provided in the music directory (HiFi) belonging to the same category.
To generate. Multiple files are placed in each music directory. One of them is the reproduction management file PBLIST. MSF (hereinafter, simply referred to as PBLIST), and the others are ATRAC3 data files A3Dnnnn.
MSA (hereinafter, simply referred to as A3Dnnn).
The ATRAC3 data file is arbitrarily created by the device after being registered in the reproduction management file. In addition to these files, a music title data file, a performer data file, an encryption key data file, etc. are stored, but they are omitted in the figure.

In the system of the present invention, two independent directories HiFi and HiFi2 are provided in the music directory (HiFi) belonging to the same category.
To generate. The contents input by the check-out process with the PC are once registered in the directory HiFi, and after the transfer process from the PC is completed, the directory H
A transfer process from the iFi to the directory HiFi2, that is, a directory change process is executed. The content registered in the directory HiFi2 is registered and managed in the content management table created in the portable medium.

A content management table generated in the information recording processing device such as a portable medium for storing content will be described with reference to FIG. In the content management table, the ATRAC3 data file name A3Dn of the content registered in the directory HiFi2 is displayed.
a content identifier (CID) associated with nnn,
And the device ID that was applied during the checkout process
Are stored in association with each other.

In the configuration of the present invention, one information recording processing device can selectively execute the checkout process by selectively using a plurality of device IDs set in the information recording processing device and stored in the memory. In the example of FIG. 7, first, the device ID = 10 as the device ID applied to the checkout process.
00 is set as the selected device ID, and the device ID = 1000
A3D0000 by the checkout process using
The contents of 1, CID = 1 to A3D00004, and CID = 4 are stored in the directory HiFi2 via the directory HiFi.

Next, the same information recording processing apparatus uses the device ID = 10 as the device ID to be applied to the checkout process.
01 is set as the selected device ID, and device ID = 1001
A3D0000 by the checkout process using
5, the contents of CID = 1 to A3D00007 and CID = 5 are stored in the directory HiFi2 via the directory HiFi. Further, the same information recording processing device sets the device ID = 1002 as the selected device ID as the device ID applied to the checkout process, and the device I
By the checkout process using D = 1002, A
3D00008, CID = 1, A3D00009, CI
The processing when the content of D = 3 is stored in the directory HiFi2 via the directory HiFi is shown.

By these processes, the directory HiF
A content management table as shown in FIG. 7 is generated corresponding to the content stored in i2.

In the directory HiFi2, the ATRAC3 data file name A3Dnnnn is
It is converted into a sequential number in cumulative order and registered. For example, when checking out for the first time, first, 15 songs are stored in the directory HiFi, and then the directory H
When moved to and stored in iFi2, A3D00001 ~
The ATRAC3 data file name of A3D00015 is given, but thereafter, for example, when three pieces of contents are stored by the check-out process, first, from the PC, the A3D0000 stored in the directory HiFi is stored.
1 to A3D00003 are converted to A3D00016 to A3D00018 and stored when moving to the directory HiFi2.

A delimiter as an album identified as a set of a plurality of A3D files, which are serial ATRAC3 data files, is a directory HiFi.
It is managed by the second reproduction management file PBLIST. When checking out, the directory HiFi
The reproduction management file PBLIST is generated in the directory HiFi2 in the directory HiFi2 during the directory moving process after the checkout. The cumulative number of 1 to 500 is reset and stored as the MSF. A3D0 which is each ATRAC3 data file based on the reproduction management file PBLIST of the directory HiFi2
Which reproduction management file P is 0001 to A3D20000
It can be identified whether it belongs to BLIST. One playback management file PBLIST corresponds to one album, and PBLIST is used to determine which ATRAC3 file belongs to which album.

Returning to FIG. 5, the description of the checkout processing flow will be continued. The PC verifies in step S103 whether or not the check-in process for the device ID included in the check-out request data received from the portable device by the PC side has been executed, as shown in FIG.
It is executed as a process for searching whether or not the content registered in the check-in / check-out management table of the device is stored in the portable medium mounted in the portable device.

In the search processing, check-in / check-in is performed corresponding to the device ID received from the PC at the time of check-out request processing.
This is executed by transmitting the content identifier (CID) registered in the checkout management table to the portable device, and the portable device searching the content management table based on the received CID. For example, the device ID received from the PC during the checkout request processing is 10
If 00, check-in / in the PC shown in FIG.
CID = 1, registered in the checkout management table
CIDs 2, 3, and 4 are transmitted to the portable device, and the portable device searches the content management table based on the received CID. In the content management table, a content identifier (CID) is stored for each device ID, and the device ID is stored without searching all data.
It suffices to extract only the data that coincides with each other and execute the search processing, which enables high-speed processing.

The content management table of the portable device as the information recording processing device is subjected to content check-in processing or deletion processing, and the entry is deleted when data is deleted from the directory HiFi2. Therefore, when there is no content identifier to be searched in the content management table of the information recording processing device, it can be considered that the content check-in processing or the content deletion processing has been executed. When the content check-in process is executed, P
The check-in / check-out management table of C is also updated, the CID entry of the check-in processing target content corresponding to the device ID that executed the check-in processing is deleted, and the check-out number count value corresponding to the content ID (CID) (C.O.) is incremented by 1.

Although the check-in / check-out management table of the PC has an entry of the content identifier (CID) corresponding to the device ID for which the presence or absence of check-in is determined, the content management table of the portable device does not. If there is no corresponding entry, it means that the check-in process is not performed and the erasing process is performed. In this case, step S in the processing flow of FIG.
The determination of 104 is No, and the deemed check-in process is executed in step S112.

The deemed check-in process is executed as a process of updating the check-in / check-out management table of the PC. That is, the corresponding entry is not detected in the content management table of the portable device, and the P
If an entry remains in the check-in / check-out management table of C, the CID entry of the check-in processing target content corresponding to the device ID is deleted and the content I
The checkout number count value (C.O.) corresponding to D (CID) is incremented by 1.

Next, in step S105, the check-out capacity is checked. In the case of music data, the check-out process is executed as a data storage process for the directory HiFi of the portable medium. Therefore, the capacity check is performed by comparing the data capacity of the check-out target content with the free capacity of the portable medium set corresponding to the directory HiFi of the portable medium. When the data capacity of the check-out target content is larger than the free capacity of the directory HiFi of the portable medium, the process proceeds to step S113, a capacity shortage message is displayed on the display of the PC, and the process ends.

If it is determined that there is no problem with the capacity, a checkout process for the directory HiFi is executed in step S106, and the reproduction management file PBLIS is written in the directory HiFi of the portable medium.
T. ATR containing MSF and encrypted music data
AC3 data file A3Dnnnn. The MSA, song title data file, performer data file, encryption processing key data file, etc. are stored. The file name of the ATRAC3 data file is sequentially generated from A3D00001. Check out multiple ATRAC3s
Data files can be transferred. For example, when 15 songs are checked out, ATRAC3 data files A3D00001 to A3D00015 are stored in the directory HiFi.

Next, in step S107, it is determined whether or not the transfer (checkout) is completed, and if it is determined that the transfer is completed, in step S108, the process of moving from the directory HiFi to the directory HiFi2 is executed. As mentioned above, the directory HiFi2
, The ATRAC3 data file name A3Dnn
nn is registered by being converted into a sequential number in the order of accumulation, and is identified as a set of a plurality of A3D files that are serially numbered ATRAC3 data files. To be done.

After the directory moving process in step S108, in step S109, the content management table is updated corresponding to the content registered in the directory HiFi2.

The content management table generated in the portable medium is as described with reference to FIG. In the content management table, the content identifier (CID) associated with the ATRAC3 data file name A3Dnnnn of the content registered in the directory HiFi2 and the device ID applied during the checkout process are stored in association with each other. It

Next, in step S110, the reproduction management file PBLIS generated in the directory HiFi.
The T and ATRAC3 data file deletion processing is executed, and the checkout processing ends.

As described above, in the configuration of the present invention, one information recording processing device can execute the checkout process by properly using a plurality of device IDs, and the PC as the content input / output management device can record the information. Management of check-out or check-in of contents associated with a plurality of device IDs of the processing device is performed. Therefore, a large amount of H
It is possible to execute the content search in the check-out / check-in process for the information recording processing device having a storage medium such as a D or an optical disc within a range limited by the device ID, which enables high-speed processing.

In the above embodiment, the music data is used as an example of the check-in / check-out target content, but the same processing can be applied to other image data, data such as programs. For example, in the case of inputting a still image as content, the information recording processing device is provided with two directories for a still image file, and is input to the first still image directory at the time of checkout, and then to the second still image directory. Execute the move process. The selective use of a plurality of device IDs is the same as the above-mentioned processing.

Next, with reference to FIG. 9, an example of the content check-out and check-in processing accompanied by the change of the device ID will be described. In the content checkout process described using FIG. 7, the device ID is changed in each of the three checkout processes, that is, device ID = 10.
The example of the process of checking out using the three types of IDs 00, 1001, 1002 has been described.

In the example shown in FIG. 9, the device ID = 1000 is applied as the selected device ID as the first process, the second process is the check-in using the device ID = 1001, and the third process is the device ID = 1000. This is an example of checking out using. The first and third processes are checkout processes using the same device ID. By thus using the same device ID, the ATR of the content registered in the directory HiFi2
It is possible to set the reproduction management file PBLIST set for the AC3 data file as common to the first and third check-out contents. That is, the first and third check-out contents can be set as contents in one album, and the setting of the reproduction order can be collectively executed.

FIG. 10 shows a case where one information recording processing device performs checkout using a new device ID, and a case where the device ID is the same as the device ID already applied to checkout.
FIG. 5 is a processing sequence diagram between the information recording processing device and the PC when the checkout processing is performed by using. The checkout process is executed according to the process described above with reference to FIG. The sequence diagram of FIG. 10 shows a new device I.

FIG. 10 (1) shows a processing sequence for performing checkout using a new device ID.
The PC confirms the capacity of the HiFi directory in the information recording processing device, and then the information recording processing device acquires one ID from the device IDs stored in the memory as the selection ID and transmits it to the PC. The PC creates a field for the new device ID in the check-in / check-out management table and records the identifier of the output content. Further, the number of check-out possible for each CID is set (C.
O. ) Decrement the corresponding count value of the output contents of the field by 1. Upon completion of the check-in / check-out management table update processing, the requested content is transferred to the information recording processing device, that is, checked out.

FIG. 10 (2) shows a processing sequence in the case of performing the checkout processing using the same device ID as the device ID already applied to the checkout. The PC confirms the capacity of the HiFi directory in the information recording processing device, and then the information recording processing device sets the same device ID as the device ID already applied to the checkout as the selection ID and transmits it to the PC. The PC confirms that the check-in / check-out management table has a field for the receiving device ID, and records the identifier of the output content in the same device ID field. Further, the corresponding count value of the output content of the (CO) field in which the number of check-out possible for each CID is set is decremented by 1. When the check-in / check-out management table update process is completed, the requested content is transferred to the information recording processing device, that is, checked out.

Checkout as shown in FIG.

For items 2 and 5, it is assumed that the device ID = 1001 is used to perform the check-out process once.

In this state, first, in the first check-out processing, the content ID = 1, 2, 3, 4 is checked out using the device ID = 1000. According to this processing, in the check-in / check-out management table on the PC side, each entry of CID = 1 to 4 is generated in the field of device ID = 1000. Further, the number of check-out possible for each CID is set (C.
O. ) Numerical values of CID = 1, 2, 3, 4 in the field are decremented by 1. As shown in the figure, C
ID = 1 is updated to 2 → 1, CID = 2 is updated to 2 → 1, CID = 3 is updated to 3 → 2, and CID = 4 is updated to 3 → 2.

Next, as the second processing, the device ID = 10
The check-in process using 01 is executed. Device ID
= 1001 is used to check in content IDs = 1, 2, and 5. According to this process, the device ID = 10 in the check-in / check-out management table on the PC side.
The entries of CID = 1, 2, 5 in the field 01 are deleted. Furthermore, the number of check-out possible for each CID is set (CID) in the (C.O.) field = 1, 2, 5
Are incremented by one. As shown in the figure, CID = 1 is 1 → 2, CID = 2 is 1 → 2,
CID = 5 is updated as 2 → 3.

Next, as the third processing, the device ID = 10
Checkout processing using 00 is executed. Equipment I
Content IDs = 5 and 6 are checked out using D = 1000. According to this processing, the check-in / check-out management table on the PC side shows the device ID = 10.
Entries of CID = 5 and 6 are generated in the 00 field. Further, the numerical values of CID = 5 and 6 in the (CO) field in which the number of check-out possible for each CID is set are decremented by one. As shown in the figure, CID = 5 is updated to 3 → 2, and CID = 6 is updated to 3 → 2.
