Realize best mode of the present invention

Hereinafter the first embodiment of the present invention will be described.A kind of profile of content delivery system at first will be described with reference to figure 1.In Fig. 1, content of reference number 101 expressions is supplied with the supplier, and content server of 102 expressions.Content is supplied with supplier 101 and is produced and provide content.A record company is that a content is supplied with supplier 101.Content is supplied with supplier 101 and is also carried out a compressed encoding, coding and watermark embedding for content.The content of being supplied with supplier's 101 generations by content is accumulated in the content server 102.

Copyright management tissue of reference number 103 expressions.For example, JASRAC (author of Japan and the association of composer's right) is a concrete example of copyright management tissue 102.Content is supplied with supplier 100 and is organized right registration 103 to receive copyright fee to copyright management tissue 103 and from copyright management.

Reference number 104 expressions have a user's set of content-data regeneration function.This provides content user's set 104 regeneration, that is, performed encryption of data and decoding compressed coding are provided in decoding, and content can be reproduced.Content is provided the supplier and is present between content server 102 and the user's set 104 and the content in the content server 102 and provides to the user as required.Some means are considered to by providing the granting means that the supplier uses.Be by storage 105 methods of providing one of among them.For example, medium that wherein write down content are issued then as the supplement of a magazine that the user buys this magazine, obtain this content thus.Here also have the cable network that uses such as Internet or CATV (cable television) to provide a kind of method of means as content.A kind of cellular radio network 107 such as satellite broadcasting, satellite communication or the like and a kind of satellite network 108 also can be used as the content dispensing apparatus in addition.By using aforesaid wired network 106, telephone network 107 and satellite network 108 to provide under the data conditions that comprises content, the user is by using a device this content of regeneration from the data of providing that comprise this content such as personal computer or the like.

The dispensing apparatus of the charged content that is issued in the present invention, is not hindered as the use of above-mentioned content dispensing apparatus.Under the situation of the medium such as CD, the copyright fee of recording musical sheet is included in the price of CD.Also might provide free musical film exactly and be decoding (regeneration) another position that the content record of charging becomes the position that is different from the CD that has been recorded charged content.

In Fig. 1, CD 121 is expressed as medium of being provided by storage 105.The zone 122 of ring on the limit is the zones of having write down the musical film data in CD 121, these musical film data have the form identical and its granting with existing C D be charge and its regeneration be free.In zone 123 on the outer annular edge of CD 121 are the present invention the zone of content application on to it, that is, write down and provided content free, the regeneration charge, for example music data.Because music data has been compressed coding as the content that is recorded in 123 li in zone, so even zone 123 is very narrow, the music data of necessary duration also can be recorded.

As the medium except above-mentioned CD 121, above-mentioned MD, a kind of storage card of semiconductor memory and a kind of IC-card of using can be used as medium, as long as granting charge, the free content of regenerating and granting content free, the charge of regenerating can be recorded in the zone that can distinguish.As mentioned above, the content-data itself of providing free and regeneration charge also can be provided by using a kind of service of using satellite television broadcasting rather than using medium to be used to provide music content.

As mentioned above, by obtaining CD 121 or serving by the granting of use content, user's set 104 can receive free content.The content that receives also can freely be provided again.When this content is provided again, for device serving as the transmission source and the peculiar identifier of regenerating unit and this content are provided together again, so that granting historical record and content regeneration/decoding historical record in that content can be seen by charge/settlement center will illustrate charge/settlement center subsequently.When content was provided again, the identifier which medium is the expression content be stored in also can be issued together with this content.The free ＂ of ＂ represents a kind of actual cost that freely and not comprises such as communication cost electric charge expense or the like about copyright fee.When the content of being received by user's set 104 is reproduced, more precisely, when the data encryption that comprises this content is decoded, carries out a charge and handle.Prepayment data 109 are used for this charge and handle.These prepayment data 109 be stored in a prepaid card or safety demoder in a storer in.As for prepayment data 109, under the management of a prepayment data management company, can be rewritten as in the data in the storer in prepaid card or the safe demoder by a clientage (charger).Prepayment data 109 for example are that content can be reproduced a degree (degree).The object content of each user's set 104 regeneration charges, then reproducible degree reduces.

Charge/settlement center 110 exists and content is supplied with supplier 101, copyright management tissue 103 and user's set 104 and cooperated to be used for cost and settle accounts.Charge/settlement center 110 has an authentication/charging server 111.This charge/settlement center 110 is a bank, a credit agency or the like.In fact, a main frame in bank or trust company is automatically carried out following processing.

When this user's set 104 was planned this received content of regeneration, this user's set 104 required authentication/charging server 111 these user's sets 104 (l represents by path A) of checking.If authentication/charging server 111 determines that user's set 104 is legal satisfied authentications, then 111 requests of authentication/charging server are to user's set 104 charges (path A 2).User's set 104 carries out cost clearing (path A 3) with authentication settlement center 111.

Shown in path A 4, charge/settlement center 110 sends the fact of carrying out charge to authentication/charging server 111 and command context server 102 emission secret key data, is used for the encryption that the data that comprise this content are carried out is decrypted (path A 5).Content server 102 is given authentication/charging server 111 (path A 6) these secret key data that are used for encryption is decrypted.This authentication/charging server 111 is given user's set 104 (path A 7) the secret key data transmission that derives from content server 102.According to the secret key data of this emission, user's set 104 can be decoded the data that comprise this content and regenerate and be comprised the data of this content.When finishing decoding, this determines that content is reproduced.The degree of prepayment data 109 for example reduces ＂ 1 ＂.When this degree arrived 0, user's set 109 can not be decoded and be comprised these data of this content, that is, it can not be regenerated and comprise these data of this content.

Fig. 2 represents to prepay the example of a management system of data 109.A player 201 is represented as an equipment that is equivalent to user 104.Player 201 wherein has a reliable decoding device 202.Player 201 for example is a portable recording and regenerating unit.In Fig. 2, shown in dotted line, music data is as comprising that the data of content have been recorded in medium (CD, storage card or the like) lining, and it is reproduced by player 201.As shown in Figure 1, the whole bag of tricks of granting music data can be used.

Reliable decoding device 202 is communicated by letter with a prepayment data clientage 204, so that the storer that the prepayment data are sent to the reliable decoding device 202 from prepayment data clientage 204.These prepayment data for example are equivalent to the number of the renewable temporal information of player 201, usually said renewable degree or renewable time.The regeneration history information (regenerative recording) of player 201 is transmitted to prepayment data clientage 204 from player 201.This regenerative recording comprised such as the various music contents of listening to, recovery time counts the information recovery time or the like.For example, this regenerative recording is stored in and is used for being stored in the storer of reliable decoding device 202 to this regenerative recording or is kept in the storer in the controller of player 201.

These prepayment data are forwarded to prepayment data clientage 204 from prepayment data management company 205 or corresponding to a prepayment automatically selling data 206 of the cash quantity of user's payment.For example, if certain user is under management company signs a contract with prepayment, that is, and the contract of buying the prepayment data with corresponding to every day  3000 renewable degree or renewable number of times corresponding.From player 201, extract the regenerative recording of giving prepayment clientage 204 and be transmitted to prepayment data management company 205 or prepayment automatically selling data 206 from player 201.This prepayment automatically selling data 206 receives from the prepayment data of prepayment data management company 205 and this regenerative recording and sends to this prepayment data management company 205.In addition, prepayment automatically selling data 206 is to the expense of management company's 205 payments from the prepayment data of the 205... of management company acquisition.

Between prepayment data management company 205 and prepayment data clientage 204, for example prepay data and regenerative recordings by 207 emissions of a telephone wire.Equally with respect to these prepayment data, such as bank, trust company, or the like a charge/settlement center 208 exist according to a request from prepayment data management company 205, charge/settlement center 208 regains an amount of money amount from user's a pre-registration bank account, this amount of money amount is equivalent to write the prepayment data in this reliable decoding device 202.At this moment wait, be written into prepayment data sum in the reliable decoding device 202 and equal that based on the contract of concluding between user and the management company 205 one is pre-to determine sum or aforesaid by prepaying a data sum of clientage 204 user's request management companies 205.

In addition, prepayment data management company 205 receives a mandate, is used to manage and the relevant service of prepayment data of supplying with supplier 101 from content.This prepayment data management company 205 provides a technology relevant with the prepayment data to supply with the expense of listening to of supplier 101 and payment musical film to content.As described with reference to figure 1, content is supplied with supplier 101 and is organized 103 copyrights to copyright management, asks copyright management thus and receives copyright fee from copyright management tissue 103.

Fig. 3 represents to have the one-piece construction of the player 201 of reliable decoding device 202.Reliable decoding device 201 is constructed to by a represented IC chip of a dotted line.This reliable decoding device 201 has a so-called anti-structure of altering.That is, this reliable decoding device 201 has such structure so that the content in demoder 201 can not be obtained from the outside and can not be altered.

Music data as be compressed coding and ciphered data comprise the content that is recorded on the medium 1.And, to have encrypted music data with compressed encoding and interrelated, the regeneration charge is handled necessary data and is stored on these medium 1.In the following description, compressed encoding has been encrypted music data and has been called content-data, and the data that the charge that is used to regenerate is handled are called ancillary data.In the present invention who will be described hereinafter, compressed encoding and encryption both carry out always not necessary.Under the situation of only carrying out compressed encoding, as long as its underground purpose of copyright of then protecting of coding/decoding method can reach equally.

As the medium 1 that are used for the present invention, storage card, CD-R, read-only optical disc or the like can be used.If medium 1 are recordable medias such as aforesaid storage card or CD-R, then by such as satellite network, use the data of the network granting cellular network, Internet or the like to be downloaded.The content-data and the ancillary data that are recorded on the medium 1 are provided for reliable decoding device 202 by an interface 2.Simulated audio signal is exported from this reliable decoding device 202.This simulated audio signal of loudspeaker that offers player 201 by earphone that is connected to player 201 by amplifier or the like or the like is converted into a sub-audible sound and is reproduced.

This reliable decoding device 202 has: a demoder 11, and this encryption is used to decode; Decompression machine (decompressor) 12 corresponding to this compressed encoding; And D/A converter 13.As the sign indicating number that is used for content-data is encrypted, DES (data encryption standards) can be used.DES is a kind of block encryption, and being used for separately becomes block encryption conversion of each block execution then to a common sentence.

By using a secret key word of 64 bits, DES carries out an input of 64 bits and encrypts conversion.On this content-data was encrypted, an encrypted code except that DES also can be used.For example, though DES is for encrypting and a kind of Public key system of identical secret key data is used in decoding,, also can use for encrypting and a rsa encryption of different secret key data is used in decoding as the example that public keys is encrypted.As mentioned above, give the user's set 104 that is satisfied authentication the secret key data from content server 102, that is, it is correctly approved by authentication/charging server 111.

This reliable decoding device 202 comprises: comprise the control module 14 of a CPU; A cpu i/f 15 is used to carry out communicating by letter between control module 14 and the outer CPU; A storage unit 16; And a communication unit 17 and an antenna 18, be used to receive from prepayment clientage's 204 prepayment data and to the prepayment clientage and launch regenerative recording.This control module 14 is received in decoding earlier stage in the demoder 11 and is in the appropriate section such as demoder 11, decompression machine 12 or the like that the ancillary data of separation and control are used to carry out the decoding and the decompression of this ancillary data and content.

Communication unit 17 and antenna 18 are carried out communication between player 201 and the prepayment data clientage 204 in a kind of contactless mode.Carry out data communication between player 201 and the clientage 204 by using an agreement of having encrypted.Communication between player 201 and the clientage 204 is not limited to transmitting and receiving of data.Because player 201 can receive the electric power from clientage 204, so even the power supply of player 201 is to close, the reception of the prepayment data between player 201 and clientage 204 and the emission of regenerative recording also can be performed.The prepayment data of receiving from clientage 204 are stored in the storage unit 16.And the regenerative recording of player 201 is stored in the storage unit 16.Storage unit 16 is a kind of nonvolatile memories, even its memory contents also is held when the power supply of player 201 is closed.

The duplicating output and can from demoder 11, output to reliable decoding device 202 outsides of ancillary data and content-data.The duplicating output and whether be output to and outside control of ancillary data and content-data by control module 14.And demoder 11 and decompression machine 12 have such function: according to the instruction from control module 14, do not carry out decoding processing and decompression.Because decoding processing and the decompression carried out by demoder 11 and decompression machine 12 are stopped, so not have the voice data of encrypting and do not have the voice data of compressed encoding, for example, a linear PCM can be played device 201 and regenerate.

A system controller 21 is provided for the integrated operation of controls playing device 201.System controller 21 constitute by a CPU and by with reliable decoding device 202 in communicating by letter of control module 14 control the operation of reliable decoding device 202.Operating unit 22, display screen 23, storage unit 24 and modulator-demodular unit 25 are connected to system controller 21 by a bus.In addition, the operation of the regenerative operation of system controller 21, medium 1 and media interface 2.

The switch of this operating unit 22 and user operation, key or the like are corresponding and produce one and be used for the instruction that controls playing device 201 is operated.Display screen 23 for example is made of a liquid crystal apparatus and is used to show that is used for the menu and device 201 modes of operation that display the play that controls playing device 201 is operated.The external storage that storage unit 24 provides is because the memory span in the system controller 21 is very little.Modulator-demodular unit 25 is connected to common line and is used to and external data communication.For example, by the regenerative recording in demoder 202 storage unit 16 is sent to storage unit 24, remainder purpose regeneration possibility number of times or the possible number of times of residue regeneration can be displayed on the display screen 23, and perhaps regenerative recording can be launched by modulator-demodular unit 25.And the prepayment data also can be received by modulator-demodular unit 25.

User's operating operation unit 22 is ordered the regeneration of the expectation content-data in the medium 1 thus.When the content-data by user's appointment is during with the relevant free data of regeneration, even the content-data of reading from medium 1 is converted into a simulating signal by reliable decoding device 202 and is output, the prepayment data that are stored in the storage unit 16 do not change.If content-data is specified by the user and regenerated is the target of regeneration charge, then the prepayment data in the storage unit 16 change.For example, in this case, the prepayment data reduce ＂ 1 ＂ or reduce according to the regeneration times of content-data.

As a charge purpose, it is that all kinds are possible that of carrying out in the regeneration of content-data charge is handled.For example, charge is handled and can be divided into substantially: a purchase pattern; A kind of type of collecting the supervision expense by the gross; And the degree type of when the reliable decoding device is separated code encryption, collecting the supervision expense.This purchase pattern is such one type: after buying content-data, when content-data was reproduced, it did not charged.The type of collecting the supervision expense by the gross is divided into so a kind of contract type monthly so that because a type of being limited or the like of a kind of contract type monthly that the caused supervision expense of regeneration of content-data is paid together and monitoring period and Looking Out Time or the like.

And as the degree type of the supervision expense of collecting when the reliable decoding device is separated code encryption, some forms are possible.According to first form, as mentioned above, when the readout of content was performed, an amount of money sum or a degree are preset in amount of money sum (prepaid card, electronic money) or a degree from one to be deducted.In this case, if lack the redundancy of remaining sum or prepayment data, then content-data can not be reproduced.According to second kind of form, amount of money sum or degree are increased when the readout data of content are performed.In this case, deferred payment for total or that the accumulation degree is suitable expense with the amount of money of accumulation on the basis of unit at one month.When accumulated amount sum or accumulation degree reach according to total or when spending, content-data can not be reproduced with prepayment data management company 205 the sign a contract amount of money that preset.According to the third form, increase or cut the degree or the amount of money sum of prepayment data according to the regeneration times of content-data.In this case, with the similar mode of situation described in top second kind of form, the user is not limited to prepayment to the expense of management company 205 or the like payment but can be sold on credit payment.

Prepayment data amount of money sum that is cut or increase or degree can be set to constant according to any content regeneration or can also be weighted according to the content-data that will regenerate.Carrying out this charge in the communication to the content (with the form of music example, photograph album) of the content of a title (with the form of the example of music, a musical film) or a large amount of titles handles.

As the method for definition content readout, in the situation that whole content-data has been reproduced, it can be defined like this so that content is reproduced.Equal or be longer than in the situation of pre-determined number at the content regeneration number of times, it also can be defined so that content is reproduced like this.In addition, be used for that sales promotion is propagated and the regeneration of the promotional content of circulation is free of charge.Even in the content of serving as the target of charging, for example under the situation of the regeneration of the anterior part of content, for example, freely carry out from the regeneration that can be set to high light part free or just content in 10 seconds of front portion, allowing thus provides content choice to the user easily.As mentioned above, under the situation that the content and the free content mix of Regeneration Treatment of Regeneration Treatment charge exists, then by with this relevance and be stored in ancillary data in the medium 1 and judge charge/freely.

Fig. 4 represents the example of a data structure of ancillary data.Ancillary data is data additional before the content-data that is issued (compressed encoding and encrypted content data, for example, voice data).As required this ancillary data is encrypted.This ancillary data is attached to before the content-data and is recorded on the recordable media or records a zone that is used for data management on the medium 1.If be read-only medium, this ancillary data is recorded in the data management zone.If be a CD, usually, owing to provide the management area in the zone on the innermost edge of this CD, so this ancillary data is recorded in this management area.For example, if be storage card, owing to a musical film of the such music data of file management data when a file is determined is processed, so ancillary data is stored in stored that storage area of file management data.

As shown in Figure 4, a fixed value (fixed code) 301 is positioned at the front portion of ancillary data.This fixed value 301 is fixed code of a byte, for example ＂ 01010101 ＂.This fixed value 301 shows that follow-up data is an ancillary data.Data after fixed value 301 will be illustrated in proper order.

Constitute by following with the relevant ancillary data of charge: the charge identifier of 1 byte (below, this identifier is called ID) 302; The charge type 303 of 1 byte; And the toll condition 304 of 32 bytes.Whether this charge ID302 order instruction content is charge or free content.Charge type 303 is the information that is used to distinguish aforesaid purchase pattern, type of population, degree type or the like.Toll condition 304 is data of the toll condition information in each charge type of expression.

For example, under the situation of above-mentioned purchase pattern, it is a toll condition 304 that the buying price data of content-data are set up (perhaps record).If limit the regeneration times of number of the regeneration times of above-mentioned type of population content-data, then the data of the content-data regeneration times number that can be reproduced are set to a toll condition 304.If be above-mentioned type of population regeneration period of restriction, then the data of regeneration period (a day, a week, month or the like) are set to a toll condition 304.If be above-mentioned degree type, then Du data (1 Yen/2 minutes, 1 Yen/1 minute, 1 Yen/30 seconds ...) be set to a toll condition 304.In addition, if even be the content that charged as condition precedent, the condition in the situation that it can freely be monitored also can be set to toll condition 304.

A CODEC type 305 is set after toll condition 304.This CODEC type 305 is formed and is used to represent the compressed encoding type of content-data by a byte.As the method that is used for compressed encoding, the AAC (Advanced Audio Coding Advanced AudioCoding) that MPEG2 (the stage 2Moving PictureExperts Group Phase2 of Motion Picture Experts Group) arranged here, MP3 (MPEG1 audio layer III MPEG1 Audio Layer III), ATRAC (adaptive transformation acoustic coding Adaptive Transform Acoustic Coding), ATRAC3 or the like.ATRAC3 is by improve to use ATRAC in above-mentioned MD and obtain and plan to realize a higher ratio of compression.

Except that codec type 305, the software of CODEC also can be used as ancillary data and is launched.The software of CODEC is used for content-data is decompressed or being deposited among the DSP of player 201 and being used for by this software content-data being decompressed by personal computer.

The channel 306 of one 1 byte is set after CODEC type 305.This channel 306 is the data that are used to discern the voice-grade channel number.The number of the voice-grade channel such as monaural, stereo, 5.1 channels or the like content-data is identified by channel 306.The bit rate 307 of one 1 byte is set after channel 306.Bit rate 307 is the data that are used to discern the bit rate of content-data, for example, and 64 kbps, 128 kbps, 192 kbps, 256 kbps or the like.

The encryption type 308 of one 1 byte is set after bit rate 307.This encryption type 308 is to be used for the data that kind (DES, RSA or the like) is encrypted in identification.Come to determine also to be possible in such a way: promptly, all be ＂ 0 ＂ when encryption type 308 shows, this refers to data and does not encrypt.The encryption parameter 309 of one 1 byte is set after encryption type 308.This encryption parameter 309 is used to bit length of representing an encryption key or the like.Consider expansion in the future, for example be provided as reservation (undefined) zone 310 in 12 bytes of encrypting after 309.

A fixed value 311 after reserve area 310 shows the zone 312 that has been provided with a medium ID after that continues.Medium ID in the zone in 312 is an ID, for example, is used to make it can unconditionally discern such as CD, MD, CD-R, comprise a sequence number of the medium the storage card or the like of a nonvolatile memory.These medium ID for example represents by 8 bytes.For example, in the zone 312 of medium ID, 32 medium ID can be set.

A fixed value 313 is set after the zone 312 of medium ID.This fixed value 313 is illustrated in that zone 314 of continuing to be provided with afterwards a demoder ID.Demoder ID is an ID, for example, is used to make it can unconditionally discern a sequence number that is installed in the inner reliable decoding device of user terminal, user's players or the like.For example, in the zone 314 of storage decoder ID, 32 demoder ID can be set.Utilize by clientage 204 and regenerative recording and launch medium ID and demoder ID to management company 205 or the like together, can discern each regenerative recording of medium and reliable decoding device by a computing machine such as management company 205 or the like.

Handle example referring now to the charge that the flow chart description of Fig. 5 is illustrated in the player 201 among Fig. 3.This charge is handled and is carried out by control module in the reliable decoding device 202 14 and system controller 21.First step S1 has represented a such regeneration standby mode, and promptly the content-data that will regenerate is present among the medium 1.In particular, the content-data of granting has been stored in situation that situation, content-data in the medium 1 be recorded in 1 li of medium or the like and has regenerated standby corresponding with this.At step S2, judge that whether this regeneration be instructed to by a start button of user's push unit 22.

If step S2 result is NO (not having), this meaning is that step S3 is done in the replicate run of content-data then.At step S3, judge whether this operation is the replicate run of the free content of regeneration.Here the content representation of free regeneration is not because the content that charge is handled is carried out in the regeneration of content-data.Judge at step S3 whether this content is the content of free regeneration with reference to the charge ID 302 (Fig. 4) in the ancillary data.If the content of free regeneration, in order to protect copyright, forbid the output of duplicating of this content-data (its encryption by by demoder 202 deciphering and decoding), that is, and to duplicate be under an embargo (the step S4) of this content-data of another device or medium.

If determined that at step S3 this operation is not duplicating of free content of regenerating, promptly, if determined this operation be the content-data of the replicate run of content-data of charge regeneration then the regeneration of charging from 202 outputs of reliable decoding device, it can be copied to another device or medium (step S5).As mentioned above, the content-data of charge regeneration freely is copied to another device or medium.In this case, the data of exporting from the reliable decoding device are content-datas of ancillary data and encrypted and compressed encoding.

If judge that in step S2 this regenerative operation is instructed to, then judge at step S6 whether the charge processing is accepted.For example, show message first on the display screen 23 of player 201, the sales promotion user answers about whether accept charge by the operation of operating unit 22 and handles thus., the user do not handle this content-data (step S7) of then can not regenerating if not accepting this charge.Owing to also have a kind of situation: it allows freely to be regenerated by the part of regeneration condition 304 indications of content-data, for example, can freely carry out the regeneration of the anterior part or the high light part of musical film, so even handle in the charge of step S7 refusal, also have a kind of situation: content-data can be monitored.If be allowed in step S7 charge processing, then at step S8, the regeneration toll condition relevant with the content-data that will regenerate is displayed on the display screen 23.According to the information and the toll condition 304 of the charge type in the ancillary data 303, toll condition is displayed to the user, follows by step S9.

At step S9, whether be purchase pattern by user's selection or definite this charge type.If judge that at step S9 charge type selected or that determine is a purchase pattern, then carrying out at step S10 that the charge that is used to buy this content-data handles is step S11 then.At step S11, in the demoder 11 of reliable decoding device 202, use by server 102 and this encryption is decoded up to the secret key data that server 111 provides.In step 512, carry out the free regeneration of content-data.Since free here regeneration expression user has bought the content-data that will regenerate and has had it individually, so the expense except that the expense that the purchase by content-data causes or not again.In this case, comprise that freely the distribution again of the content-data that will regenerate to another user's emission or duplicate is under an embargo.Yet, move to handle, that is, such one is different from the processing of duplicating, and the original contents data do not remain on the copy source and this content-data is launched only exists in and duplicates on the destination so that can carry out this content-data.

If selected or definite charge type is not a purchase pattern step S9 user, then select by the user or determine whether this charge type is type of population at step S13,, for example, contract type monthly.If at step S14, monthly contract exists, and for example, can be reproduced up to every charge per month accumulation at content-data based on contract monthly and to reach under the situation of  3000, judges whether this accumulation has reached the restriction sum of  3000.If this accumulation does not also arrive the restriction sum of  3000, carry out the free regeneration of content-data in step 15.In addition do not cause expense in the regeneration of the content-data in the total scope of restriction that free regeneration is illustrated in contract here.In this case, comprise that content-data duplicates or distributing again and can be carried out by the gratis to another user's forwarding with the state identical with ancillary data.

If selected or definite charge type is not a contract type monthly step S13 user, it is the data of charging by the method for degree of being equivalent to type that content-data is confirmed as.At step S17, being encrypted in the reliable decoding device 202 of content-data is decoded.Charge regeneration is performed in step S18.As mentioned above, in the charge of step S18 regeneration, regeneration is charged according to the regeneration degree of content-data, regeneration times or the like.Still in this case, content-data can be duplicated by the gratis.

In addition, if judge that in step accumulation is not in the scope at contract monthly, for example, even when it has exceeded the restriction sum of this contract, then in the regeneration of content-data the processing of charge regeneration (step S17 S18) is performed.

Another example that Fig. 6 represents to charge and handles.Because it is shown in Figure 5 that the processing till step S9 (wherein the user selects or determines whether charge type is purchase pattern) is similar to, so they are omitted in Fig. 6.At step S9, when selected or definite charge type is purchase pattern as the user, then determine that according to remaining on prepayment data in the user's players 201 charge whether may.If this charge is possible, then carry out free regeneration in the mode that is similar to step S12 at step S22.Though not expression among Fig. 6, step S10 between step S21 and S22 in the execution graph 5 (buying charge handles) and step S11 (decoding processing of encryption).Forbid equally the distribution again and the output of the content-data that is used to duplicate in the mode that is similar to step S12.

If judge that at step S23 charge is impossible, then require an additional or storage again of the amount of money sum of prepayment data at step S23.The user for example activates one by the operating unit 22 of operating player 201 and stores menu again, replenishes the amount of money sum or the degree of prepayment data thus with a kind of online mode.The present invention is not limited to this online mode but also can temporarily interrupts Regeneration Treatment, and player 201 is connected to clientage 202, carries out then and should replenish.Judge once more at step S24 whether this charge is possible.If determine that at step S24 this charge is possible, then handling procedure advances to step S22.If determine that at step S24 this charge is impossible, then judge that to be similar to charge type is not the mode of the sort of situation of purchase pattern in step S9, handling procedure advances to step S25.In the drawings, when determining that at step S24 this charge type is not a purchase pattern, this charge type degree of being confirmed as type then.

Step S25 is an inquiring user about a step of whether accepting to charge and handle.For example, a query messages is displayed on the display screen 23 of player 201.In response to this, user's operating operation unit 22, relevant of whether accepting this charge of input replys thus.When step S25 user does not accept this charge, this content-data (step S26) of then can not regenerating.Yet as mentioned above, also have a situation: the regeneration of the free regenerating section of being represented by regeneration condition 304 in content-data is allowed to.

When this user of step S25 accepts this charge, then judge with reference to prepayment data (remaining sum, redundancy or the like) whether this charge is possible at step S27.If judge the charge possibility, then carry out the charge regeneration of content at step S28 at step S27.In the charge regeneration of in step S28, carrying out, carry out charge according to regeneration times and handle.For example, after the regeneration beginning,, carry out the charge processing once more with the regeneration of valuation execution on time in 10 minutes and when the recovery time surpasses 10 minutes.Though not expression among Fig. 6, the processing among the step S17 in Fig. 5 (decoding of encryption) is performed and content-data is reproduced.With with Fig. 5 in the similar mode of step S18 situation, in step S28 content-data duplicate or the distribution step again of data can be carried out by the gratis.

When carrying out this charge regeneration at step S28, for example, a timer that provides in control module 14 is activated.At step S29, whether a schedule time has expired and overtime whether the generation when judging from the regeneration beginning.If the schedule time expires when step S29 determines from content-data regeneration beginning, then handling procedure is got back to step S27 and is judged once more whether this charge is possible.Therefore, stop such situation, that is, do not allow content-data to be reproduced and charge and handle and to carry out, then carry out charge regeneration though remain enough prepayment data sums.

If determine that at step S27 charge is impossible, then continue step S30 and be used to carry out replenishing of expense that charge handles or the like to customer requirements.After that, judge once more at step S31 whether this charge is possible.At step S31, the user does not carry out replenishing of the amount of money or the like and determines that so once more this charge is impossible, then the regeneration of content-data be under an embargo (step S32).Determine that charge is possible so once more if carry out replenishing of the amount of money or the like, then continue step S28 and carry out the charge Regeneration Treatment step S31 user.

The processing of expression in above-mentioned Fig. 5 and 6, though the control and treatment of duplicating of the Regeneration Treatment of content-data and content-data is performed as public processing, the replication processes of content-data can be separated to carry out.Fig. 7 is a process flow diagram of the example that duplicates control and treatment of content-data.First step S41 represents by a button of the replicate run that is used for operating unit 22 by user's operation or the like caused a kind of standby mode that duplicates.

Whether at step S42, whether the content-data that judgement will be duplicated is the target that is used to charge, that is, be the charged content data.If the content-data that will duplicate at step S42 is not the target of charge, that is, it is free content-data, and then duplicating of this content-data is allowed to (step S43).If this content-data that will duplicate is the target of charge, then judge at step S44 whether the user allows charge (this charge is essential when duplicating this content-data).If when step S25 user does not allow this charge, the duplicating of this content-data be under an embargo (step S45) then.

When step S44 user allows this charge, continue step S46 and judge whether this charge is possible.If the remaining sum of prepayment data, redundancy or the like are examined and charge if possible, continue step S47.Carrying out this charge handles and reproduced content data.At step S46,, then require the user to replenish advance charges (step S48) if prepayment remaining sum of data and redundancy equal 0 or not have to remain remaining sum and redundancy and the impossible words of charging that enough allow the prepayment data that this content-data is reproduced.Though expression among Fig. 7, if after step S48, replenished the prepayment data and the user has replenished the amount of money, then can reproduced content data.

Referring now to Fig. 8 and follow-up accompanying drawing a kind of data recording and/or regenerating unit and its method according to the second embodiment of the present invention are described.For those common parts of above-mentioned first embodiment are represented with identical reference number and will be carried out their detailed description by using among first embodiment those total contents.

Fig. 8 represents another example of the data structure of ancillary data.This ancillary data is data additional before the content-data that is issued (content is compressed encoding and encrypted content data, for example, voice data).This ancillary data and content-data are encrypted together or encrypted independently as required.This ancillary data is attached to before the content-data and is recorded on the recordable media or records a zone that is used for data management on the medium 1.Under the situation of read-only medium, this ancillary data is recorded in the data management zone.If be a CD, owing to provide the management area in the zone on the innermost edge of this CD usually, so this ancillary data is recorded in this management area.If for example be to be kept at card, because the processed and ancillary data of a musical film of the such music data of file management data is stored in that storage area that this file management data is saved when a file has been determined.

As shown in Figure 8, a fixed value (fixed code) 501 is positioned at the front portion of ancillary data.This fixed value 501 is fixed code of one 1 byte (8 bit), for example: ＂ 11110000 ＂.This fixed value 301 shows that the data after fixed value 501 are ancillary datas.Data after fixed value 501 will be illustrated in proper order.

The sum of the content 502 of 8 bits is represented the sum that wraps, for example, and the content in the CD.After that, (record) context number 503 (8 bit) is set.Context number 503 for example represents to be recorded in the order in the sum of the content on the CD, and first (#1) content is set at the primary importance place.Represent the satellite information relevant from the unit of 256 bits of context number 503 beginning with #1.

After context number 503, a title 504 (128 bit) of content is set.This title 504 is described a title and an ISRC (ISRC) (copyright sign indicating number).The language and the code that are used to describe title are determined in advance.After content title 504, flag F LG1 (505) is set, FLG2 (506), FLG3 (507) and FLG4 (508), its each comprise 4 bits.

This flag F LG1 (505) show content copyright existence or do not exist.If this content does not have copyright, flag F LG1=0000 then.An example as the content that does not have copyright for example, has such content here: promptly, and based on a protection period this copyright calcellation then at the expiration of the Copyright Law.This flag F LG2 (506) show content-data encryption existence or do not exist.If this content is not encrypted, then flag F LG2=0000.Usually, there is not the content-data of copyright not encrypted.Whether whether this content is the content that is used for sales promotion in mark flg3 (507) expression.If this content is used for sales promotion, flag F LG3=0000 then.Mark flg4 (508) shows whether whether this content is by the individual formed original contents such as user or the like.If this original contents is formed by individuality, for example he forms FLG4=0000 himself by the user.

After above-mentioned mark 505,506,507 is with 508, be provided with and the relevant satellite information of charging.Can judge that by a kind of method whether content is that the content that is performed as condition precedent is handled in charge, if flag F LG1 (505) is designated as (0000) at least one of FLG4 (508), then such content is the content of unnecessary charge.Constitute by the charge type 509 of 8 bits and the charge treatment conditions 510 of 96 bits with the relevant satellite information of charge.Charge type 509 is to be used to distinguish aforesaid information such as charge type, type of population, degree type or the like.Charge treatment conditions 310 are the data that are illustrated in by the information of the charge treatment conditions in each charge type of charge type 509 expressions.

For example, when charge type was purchase pattern, it was charge treatment conditions 510 that the buying price data are set up (perhaps record).Be limited if charge type is the regeneration times number of type of population and content-data, then the instruction content data regeneration may number of times data be set to charge treatment conditions 510.If charge type is to be limited the regeneration period of the content-data of type of population, then be set to charge treatment conditions 510.If charge type degree of being type, then Du data (1 Yen/2 minutes, 1 Yen/1 minute, 1 Yen/30 seconds ...) be set to one the charge treatment conditions 510.In addition, if even be the content that charge is performed as condition precedent, the condition in the situation that free content can monitor also can be set to the treatment conditions 510 of charging.

In the information (256 bit) relevant afterwards, be provided with and the relevant information of next content (context number #2) with foregoing numbering #1.A kind of structure of the information relevant with context number #2 has and is similar to those a kind of data placement relevant with above-mentioned context number #1.Put down in writing hereinafter with the relevant information of full content in the bag.

Be described in another example of the charge processing of carrying out in the player 201 referring now to Fig. 9 and 10.Control module 14 and system controller 21 in this cash desk reason reliable decoding device 202 are carried out.First step S51 has represented a such regeneration standby mode, wherein wants the content-data of reproducing contents to be present among the medium 1.In particular, the content-data of granting has been stored in situation that situation, content-data in the medium 1 be recorded in 1 li of medium or the like and has regenerated standby corresponding with this.At step S52, come marker for determination FLG1 (505) whether to equal (0000) with reference to the flag F LG1 in the satellite information (505) to FLG4 (508), judge thus whether the content-data that will regenerate is the content-data of essential charge at least one of FLG4 (508).

The result is at step S52, and one of them equals ＂ 0000 if flag F LG1 is to FLG4, and then to be confirmed as be the content-data that unnecessary charge is handled to the content-data that will regenerate.Judge at step S53 reference marker FLG2 whether this content-data is encrypted content data.If it is encrypted content data that the content-data that will regenerate at step S53 is confirmed as, then the encryption of content-data is decoded at step S54.Carry out free regeneration at step S55.If content-data is not encrypted, then skips steps S54 carries out free regeneration in step 555.By using a key, the decoding of encryption is performed in the demoder 11 of reliable decoding device 202.

If all flag F LG1 are not equal to ＂ 0000 ＂ and are confirmed as at step S52 content-data to FLG4 is that charge is used as the content-data that condition precedent is carried out, then judge with reference to the charge treatment conditions in the satellite information 510 whether this content-data is to buy content-data.If judge that at step S56 the content-data that will regenerate is not to buy content-data, then handling procedure advances to the step S60 in Figure 10 process flow diagram.

If judge that at step S56 the content-data that will regenerate is to buy content-data, then reference marker FLG2 (506) determines at step S57 whether the content-data that will regenerate is encrypted content data.If encrypted, then the encryption of content-data is decoded and carry out free regeneration at step S59 at step S58 at the content-data that step S57 will regenerate.If＞the content-data that will regenerate at step S57 is not have content data encrypted, skips steps S58 and carry out free regeneration then at step S59.Here, the free regeneration among the step S12 in free regeneration and the process flow diagram that Fig. 5 represents has the identical meaning.If the content-data of essential charge it has been generally acknowledged that then such data are encrypted.Yet,, also have the situation that content-data is not encrypted if it is very difficult that compressed encoding is decompressed.The free regeneration meaning in step S59 is because this content-data was purchased in the past, so the regeneration of such content-data is free, and comprises to another user's transmission content data with to the distribution again of other this content-data of medium replication and being under an embargo.With with above-mentioned Fig. 5 in step S12 similar fashion in the process flow diagram represented, move, that is, be different from and duplicate, a kind of like this processing is possible: do not have content-data to remain on to serve as on one side of copy source and content-data only is present in and duplicates purpose on one side so that it can be reproduced.

The processing of flow chart description in the situation that the definite content-data that will regenerate of step 556 is not the purchase content-data referring now to Figure 10.In step 560, select or judge whether content-data is purchased by the user.If at step S60, present purchase condition and user according to determining it when precondition to the user.For example, a purchase condition and a query messages are displayed on the display screen 23 of player 201.Whether the user buys it about him thus and replys according to screen content operating operation unit 22.

If determine that step 560 user he buys the content-data that will regenerate, then judge at step S61 whether the charge of buying content-data may according to the prepayment data of player 201.If determine that at step S61 charge is possible, continue step S22 and needn't carry out the charge processing with regard to the reproducing contents data.Though in order not represent in the picture space of saving among Figure 10, carrying out processing in step S53 and S57 (about the whether encrypted judgement of content-data) and the processing (decoding processing of encryption) in step S59 and S58 between step S61 and the S62 among Fig. 9.

If judge that at step S27 the charge of content-data is impossible, then continue step S63 and replenishing or recovery to the customer requirements amount of money.The user is connected to player 201 or clientage 204 to player 201, activates for example supplement menu, and replenishes amount of money total value or degree in online mode to the prepayment data.The present invention is not limited to this online mode but can temporarily interrupts this processing equally, and player 201 is connected to clientage 204, carries out from this clientage 204 then and replenishes.Whether the charge of judging the purchase content-data at step S64 once more may.If judge that at step S61 charge is possible, then continue step S22 and content-data and be reproduced.If determine buying the charge of content-data at step S24 is impossible, then with the similar mode of the sort of situation of in step S60, determining not buy content-data, handling procedure advances to step S65.

Step S65 is used to inquire about a whether received processing of this charge.In step, for example, this query messages is displayed on the display screen 23 of player 201.In response to this, reply thus about whether accepting this charge user's operating operation unit 22.If do not accept this charge step S65 user, the regeneration that then continues step S66 and this content-data is under an embargo.Here also has a kind of situation: allow the part of the content-data that will regenerate freely to regenerate according to charge treatment conditions 510.

When step S65 user allows to charge, continue step S67 and judge with reference to prepayment data (remaining sum, redundancy or the like) whether this charge is possible.If step S67 judge charge may, carry out then that charge is handled and to content-data regenerate (step S68).

Under the situation of carrying out in step S68 that charge is handled and content-data being regenerated, a timer that provides in control module 14 is provided control module 14.At step S69, whether a schedule time disappears when judging from the regeneration beginning.If disappear from the content-data schedule time in when beginning regeneration at step S69, then handling procedure is got back to step S67 and is judged once more whether this charge is possible.Therefore, stop so a kind of situation: promptly,, carry out regeneration though fail to carry out charge.

If judge that at step S67 charge is impossible, then at step S70 to replenishing of customer requirements expense or the like.After that, judge at step S71 whether this charge is possible.If＞step S71 determine once more this charge can not then, the regeneration of this content-data be under an embargo (step S72).If step S71 determine this charge may, then handling procedure is got back to step S68 and is carried out the Regeneration Treatment of this content-data.

The processing of expression in above-mentioned Fig. 9 and 10, though the control and treatment of duplicating of the Regeneration Treatment of content-data and content-data is set to public processing, also can with above-mentioned process flow diagram shown in Figure 7 in the similar mode of processing represented carry out the control procedure of duplicating respectively.

Though be illustrated substantially about the audio content in the foregoing description, also can be applied to the present invention on the content such as video data, Still image data, character data, computing mechanism diagram data, Games Software, computer program or the like except that voice data in the mode that is similar to above-mentioned those modes.
