When controller 420 determines not allow free copied content data in step S113, it proceeds among the step S118, its determines last copy Limit Type discerning what this copy Limit Type is in step S118, and limits corresponding to the last copy Limit Type control copy of being discerned.When copy can not or have been finished, controller 420 withdrawed from the program in accompanying drawing 6 and 7.
After this, when last copy Limit Type indication was forbidden copying, controller 420 was forbidden copy.When the indication of last copy Limit Type only can the limited number of times of copied content data, controller 420 made it can the copied content data.
In the end copy under the situation that Limit Type indication should copy such as SCMS according to any other method for limiting, controller 420 is corresponding to specified copy restriction method control copy restriction.Therefore, content-data also has supports the specified information that joins copy restriction method wherein, and for example separates in copy restricted information separation circuit 402 and extract this information.Certainly, can also provide special-purpose circuit to come from content-data, to extract the information of supporting specified copy restriction method.
In register 400 according to first embodiment, copy restricted information separation circuit 402 only extracts required information such as copy restricted information, content-data identification information etc., and copy restricted information generation circuit 405 and combiner circuit 404 only change required information such as the copy restricted information.Yet the present invention is not limited to this set in the present embodiment.
Certainly, copy restricted information separation circuit 402 also is suitable for record-header part and the content-data with the content-data of the form transmission of file each other partly separated, and copies restricted information generation circuit 405 and combiner circuit 404 for example also is suitable for changing whole record-header part.
Second embodiment:
[comprising in a second embodiment data transmission method and recording medium]
In aforesaid first embodiment of the invention, 1 described with reference to the accompanying drawings as mentioned, pre-determine indication and be suitable for the data in the time limit that copies Limit Type to indicate the time limit that mustn't copy the time limit and be suitable for copy Limit Type A.
Yet, in one case, it is desirable to forbid the copied content data, and allow the time limit subsequently to copy 5 times for the predetermined time limit, do these (copies nearly 5 times) as long as use identical register.In other cases, it is desirable to only allow to copy 1 time, as long as the identical register of use is done these (only copy once) and forbidden copying in the time limit subsequently for the predetermined time limit.
As indicated above, for example according to content-data, the time limit that it is desirable to freely to select the copy Limit Type and use the copy Limit Type.Yet, if can from the record-header of content-data, extract about time limit of using the copy Limit Type in register one side but can not differentiate the desirable copy Limit Type of time limit that is suitable for the copy Limit Type, then in register, can not correctly copy restriction.
According to second embodiment, the data of the copy Limit Type in the time limit data defined time limit of indication by being suitable for the copy Limit Type were joined in the time limit that is suitable for copy Limit Type A, and the content-data of data of the copy Limit Type in data with the time limit that joins suitable copy Limit Type A wherein and the indication defined time limit of data in time limit by being suitable for copy Limit Type A is provided by recording medium or communication network.
Therefore, on the same day (that day of record) was in by the defined time limit in time limit that joins the suitable copy Limit Type A in the content-data time, then in register can by visit join in the data in the time limit that is suitable for the copy Limit Type copy restricted type data and according to coming the copy of limiting content data by the indicated copy Limit Type of copy restricted type data.That is, can make the time limit that is suitable for the copy Limit Type and copy Limit Type and the content-data that will copy is differed from one another.
Accompanying drawing 8 is explained data transmission method and the recording medium that is included in the second embodiment of the present invention.According to second embodiment, in the record-header HD of the content-data by recording medium or the file layout that communication network provided, provide 4 the first copy Limit Type zone C P1,32 the first Close Date area E D1 that is suitable for the time limit of copy Limit Type, 4 the second copy Limit Type zone C P2,32 second be suitable for the Close Date area E D2 in the time limit of copy Limit Type, 4 the 3rd copy Limit Type zone C P3, as shown in Figure 8.
The data of indication suitable copy Limit Type in the time limit of the first suitable copy Limit Type in the first copy Limit Type zone C P1, have been provided with.In addition, in this second embodiment, the copy Limit Type can be similar to the copy Limit Type in first embodiment.
That is, second embodiment uses 5 kinds of copy Limit Types, promptly " mustn't copy (1111) ", " only copying (1110) 1 time ", " copy can reach (1101) 5 times ", " according to SCMS (1100) " and " freely copying (0000) ", as shown in Figure 8.
Any in the copy Limit Type in above-mentioned 5 selected by content-data provider.Selected copy Limit Type is arranged among the first copy Limit Type zone C P1.At the example shown in the accompanying drawing 8, in the first copy Limit Type zone C P1, the data of binary-coded decimal " 1111 " as expression copy Limit Type are set, that is, and the data of expression " mustn't copy ".
As shown in drawings, expression first being suitable for the Close Date data of the Close Date in the time limit that copies Limit Type is arranged among Close Date in the time limit area E D1 of the first suitable copy Limit Type as binary-coded decimal.According to second embodiment, because the Close Date data only are set in area E D1, so first time limit that is suitable for the copy Limit Type was before the date represented by Close Date in the time limit data of the first suitable copy Limit Type.That is, in the example shown in the accompanying drawing 8, first time limit that is suitable for the copy Limit Type was before July 31 calendar year 2001 for example.
The data of the copy Limit Type of indicating the time limit that is used for the second suitable copy Limit Type are set in the second copy Limit Type zone C P2.With the same in the first copy Limit Type zone C P1, will be arranged among the second copy Limit Type zone C P2 by selected any copy Limit Type of content-data provider in aforementioned five kinds of copy Limit Types.In the example shown in the accompanying drawing 8, in the second copy Limit Type zone C P2, the data of binary-coded decimal " 1110 " as indication copy Limit Type are set, i.e. the data of expression " only copy once ".
Form with binary-coded decimal is provided with the Close Date data that expression second is suitable for the Close Date in the time limit that copies Limit Type in Close Date in the time limit area E D2 of the second suitable copy Limit Type.According to second embodiment, second time limit from next day by the represented date of Close Date in the time limit data of the first suitable copy Limit Type that is suitable for the copy Limit Type lasted till Close Date in time limit on the represented date of data by the second suitable copy Limit Type.That is, for example in the example shown in the accompanying drawing 8, last till on July 31st, 2002 for second August 1 time limit from calendar year 2001 that is suitable for the copy Limit Type.
In the 3rd copy Limit Type zone C P3, be arranged on the data of the indication copy Limit Type that uses after the time limit of having passed through the second suitable copy Limit Type.As in the first and second copy Limit Type zones, will be arranged in the 3rd copy Limit Type zone by selected any copy Limit Type of content-data provider in five kinds of copy Limit Types.
In the example shown in the accompanying drawing 8, in the 3rd copy Limit Type zone C P3, the data of binary-coded decimal " 0000 " as expression copy Limit Type have been set, that is, and the data of expression " freely copying ".According to second embodiment, by the represented copy Limit Type of data in the 3rd copy Limit Type zone C P3 is to copy Limit Type at last, and after the time limit of having passed through the second suitable copy Limit Type, according to limiting by the represented copy Limit Type control copy of data in the 3rd copy Limit Type zone C P3.As shown in Figure 8, after the 3rd copy Limit Type zone C P3, be content-data.
Note, still in a second embodiment, will except various data copy restricted information join in record-header HD the same with first embodiment.Other data comprise that for the unique beacon information of content-data such as ISRC (ISRC), these information can be used for the sign of content-data.
In addition, as indicated above, in order to produce CD as recording medium, in this recording medium, write down content-data, in this content-data, add data, the expression first and second of representing the first and second copy Limit Types and be suitable for the data of Close Date in time limit of copy Limit Types and the data of representing the 3rd copy Limit Type, can use the pressing mold of being made by stamper, this stamper is formed by 2 records of having described with reference to the accompanying drawings.Can produce CD in batches, and the disk distribution that will be produced thus is to each final user.
As shown in the accompanying drawing 3, by making content-data serve the final user such as the transmission of the Internet through communication network.That is, first and second embodiment differ from one another aspect the data in joining content-data, but they do not have bigger difference content-data being offered aspect the final user.
As shown in the accompanying drawing 8, the register that is used for the copied content data can be with 4 described registers 400 be identical with reference to the accompanying drawings, also added the data that expression is applicable to the copy Limit Type in each time limit in this content-data.Yet the data that also additionally comprise expression copy Limit Type are as the copy restricted information that will extract from the content-data register.
Note, the register that is used for the copied content data in a second embodiment is the register 400 at accompanying drawing 4, illustrated and described the recording process of the copy that is used for content-data, the data that will be suitable for the time limit of copy Limit Type join in the record-header of this content-data, as shown in Figure 8 with the data that expression copies Limit Type.
[comprising the data recording in the register in a second embodiment]
With reference now to accompanying drawing 9,, is depicted as the recording operation stream that in the register 400 of the second embodiment of the present invention, carries out.When importing recording instructions by the key operation control module 422 of user operation records device 400, by entry terminal 401 content-data is transported to register 400, the controller 420 of register 400 is operated as shown in Figure 9.
In a second embodiment, the copy restricted information separation circuit 402 of register 400 separates and extraction copy restricted information, this copy restricted information comprises as in the data in the first copy Limit Type zone C P1 as shown in the accompanying drawing 8, in first data that are suitable among Close Date in the time limit area E D1 that copies Limit Type, data in the second copy Limit Type zone C P2, in second data that are suitable among Close Date in the time limit area E D2 that copies Limit Type, data and content-data beacon information in the 3rd copy Limit Type zone C P3, and with these data delivery in controller 420.
In step S201, content-data beacon information that controller 420 visits are carried from aforesaid copy restricted information separation circuit 402 and copy restricted information.Then in step S202, controller 420 is visited the current date of being preserved by time holding circuit 421.
In step S203, controller 420 determines whether to drop on the same day first based on the copy restricted information of having visited and the current date of having visited in step S202 in step S201 was suitable in the time limit of copy Limit Type.When dropping in the time limit of the first suitable copy Limit Type definite same day in step S203, controller 420 proceeds among the step S204, the data of its visit expression first copy Limit Type in step S204 (from the data of the first copy Limit Type zone C P1).
Among the step S205, the controller 420 identifications first copy Limit Type also limits according to the first copy Limit Type control copy of being discerned thus then.Because the first copy Limit Type is " mustn't copy (1111) " in a second embodiment, so controller 420 controlling recording control circuit 403 in step S205 is not transported to content-data in the combiner circuit 404 and it is impossible to notify the user to copy by for example display unit 423.After completing steps S205, controller 420 withdraws from the program in accompanying drawing 9.
When determining that in step S203 the same day is not when first is suitable in the time limit that copies Limit Type, controller 420 proceeds among the step S206, determines based on copy restricted information of having visited and the current date of having visited whether (with the same in the step S203) date on the same day is suitable in the time limit of copy Limit Type second in step S206 in step S201 in step S202.
When determining that in step S206 be the same day when second is suitable in the time limit that copies Limit Type, controller 420 proceeds among the step S207, the data of its visit expression second copy Limit Type in step S207 (from the data of the second copy Limit Type zone C P2).
In step S208, controller 420 identifications second copy Limit Type and copy restriction according to the second copy Limit Type control of being discerned then.Because the second copy Limit Type is " only copy once (1110) " in a second embodiment, thus controller 420 in step S208, visit the content-data beacon information of from copy restricted information separation circuit 402, carrying and and also content-based data beacon information visit copy count storer 422.
Controller 420 determines whether to surpass the copy number of times of content-data.When not surpassing the copy number of times, controller 420 controlling recording control circuits 403 output to combiner circuit 404 to allow the copied content data with content-data.In addition, when having surpassed the copy number of times of content-data, controller 420 controlling recording control circuits 403 are not transported to this content-data in the combiner circuit 404 and by for example display unit 423 notifies the user not copy.After completing steps S208, controller 420 withdraws from the program shown in the accompanying drawing 9.
When determining that in step S206 be the same day after second is suitable for the time limit of copy Limit Type, then controller 420 proceeds to step S209, the data of its visit expression the 3rd copy Limit Type in step S209 (from the data of the 3rd copy Limit Type zone C P3).
In step S210, the copy Limit Type that controller 420 identifications the 3rd copy Limit Type and basis are discerned is thus controlled the copy restriction then.Because the 3rd copy Limit Type is " freely copying (0000) " in a second embodiment, therefore this content-data is outputed to combiner circuit 404 to allow this content-data of copy at step S210 middle controller 420 record control circuits 403.
As indicated above, in the register in a second embodiment, be when first is suitable in the time limit that copies Limit Type, according to copying restriction by the represented copy Limit Type control of the first copy Limit Type zone C P1 on the same day (that day of record).On the same day (that day of record) was when second is suitable in the time limit that copies Limit Type, according to copying restriction by the represented copy Limit Type control of the second copy Limit Type zone C P2.On the same day (that day of record) was when second is suitable in the time limit that copies Limit Type, according to copying restriction by the represented copy Limit Type control of the 3rd copy Limit Type zone C P3.
Therefore, visit copy restricted type data and the time limit data that are suitable for the copy Limit Type can make the copy restriction consistent with the intention of content-data provider in the register of second embodiment.The time limit that can make the copy Limit Type and be suitable for the copy Limit Type differs from one another in each content-data, and according to the copy of the provider of content or copyright owner's intention limiting content data.
Notice that in a second embodiment, first, second and the 3rd each copy Limit Type that copies in the Limit Type are described as " mustn't copy ", " only copy once " and " freely copying ", as shown in Figure 8.Yet the present invention is not limited to these copy Limit Types, but can also use all kinds except the above-mentioned type according to the intention of content-data provider, and each can freely be set be suitable for the time limit that copies Limit Type.
In aforesaid first and second embodiment, as being illustrated in the data of having passed through copy Limit Type applicatory after the deadline date, as 1 and 8 having described equally with reference to the accompanying drawings, last copy Limit Type area E T and the 3rd copy Limit Type zone C P3 are joined in the content-data.Yet the present invention is not limited to this copy restricted type data.
For example, when having determined the last copy Limit Type of all content-datas, in last copy Limit Type area E T and the 3rd copy Limit Type zone C P3, do not need to be provided with any data.After having passed through the time limit that is suitable for last copy Limit Type, can control the copy restriction in a predetermined manner, such as forbidding content-data copy, free copied content data or the number of times of content-data copy being set.
In aforesaid first and second embodiment, as the time limit that provides two to be suitable for the copy Limit Type with reference to the accompanying drawings as described in 1 and 8.Yet the present invention also is limited to this time limit.A copy Limit Type can also be provided or surpass two copy Limit Type.In this case, predetermined copy Limit Type is assigned to each time limit in first embodiment, and the data that will represent the copy Limit Type in each time limit simultaneously join content-data in a second embodiment.
Providing many (such as two, three, four,) be suitable under the situation in copy Limit Type time limit, the copy Limit Type can be assigned to for first time limit separately, and simultaneously as the aforementioned second embodiment data that equally will represent to copy Limit Type join second and the time limit subsequently in each time limit in.
Interchangeablely be, providing many (such as two, three, four,) be suitable under the situation in copy Limit Type time limit, the copy Limit Type can be assigned to for first time limit separately, and simultaneously as the aforementioned first embodiment equally will copy Limit Type be assigned in advance second and the time limit subsequently in each time limit in.
Under the situation that many suitable copy Limit Type time limits are provided as indicated above, for a content-data, can use the time limit of the copy Limit Type that correspondingly is assigned to the position that it added therein in advance together and will copy the restricted type data adding time limit wherein.The position that can freely determine to specify the position in the time limit that copies Limit Type therein in advance and add the time limit of the data of representing the copy Limit Type.
In aforesaid first and second embodiment, the data of the copy Limit Type that expression is last join in the content-data.Yet the present invention is not limited to this set.For example, for all registers, be under the situation of " freely copying " or " mustn't copy " pre-determining the copy Limit Type, can not will represent that the data that copy Limit Type at last join in any content-data.
In other words, for all registers, can determine to copy at last Limit Type uniformly.Can set in advance the last copy Limit Type of each register.For example, content-based data beacon information etc. can make last copy Limit Type along with each content-data that will copy is differing from each other.
[playing restriction control]
First and second embodiment of the present invention have been described hereinbefore about copy restriction control aspect.Similarly, broadcast that can the limiting content data.Promptly, data by being provided at the time limit that has wherein added suitable broadcast Limit Type or play the restricted type data and be suitable for the content-data of the time limit data of playing Limit Type, broadcast restriction that can the control content data in the player of play content data.
Accompanying drawing 10 is explained the distribution of the content-data of the time limit data that added suitable broadcast Limit Type therein.Be similar to the content-data of adding suitable copy Limit Type time limit data as shown in Figure 1, will be suitable in this example among the record-header HD of content-data that the time limit data of playing Limit Type join file layout.
As shown in Figure 10, the time limit data area of the suitable broadcast Limit Type in the record-header HD of content comprises as forbidding maybe mustn't playing time limit zone NP, suitable Close Date in the time limit area E D2 of Limit Type A and the last broadcast Limit Type area E T of playing similar broadcast of the copy Limit Type as shown in the accompanying drawing 1.
Broadcast is forbidden maybe mustn't playing time limit zone NP and is comprised region S T1 and Close Date area E D1 Start Date.Be provided with Start Date in the time limit of forbidding playing the content-data record-header HD after among the region S T1 in the Start Date that mustn't play time limit zone NP, in the Close Date area E D1 that mustn't play regional NP of time limit, be provided with the end data in the time limit of forbidding the play content data.In the example shown in the accompanying drawing 10, for example content-data mustn't copy time limit since on August 1st, 2000 and stop on August 31st, 2000.
In the Close Date area E D2 that is suitable for the time limit of playing Limit Type A, be provided with according to being suitable for and play the Close Date that the time limit of content-data after record-header HD is play in Limit Type A restriction.Be suitable for and play the number of times that Limit Type A restriction is for example play, for example its indication " is play nearly 5 times (in identical register) ".
In the example shown in the accompanying drawing 10, last till on September 30th, 2000 time limit from the September 1st, 2000 (promptly in next day that mustn't play 31 days Augusts in 2000 in the time limit) that is suitable for broadcast Limit Type A (restriction is play 5 times) always.
The data be illustrated in suitable broadcast Limit Type A available after the time limit of having passed through suitable broadcast Limit Type A are set in last broadcast Limit Type area E T.In this example, the data that will represent " freely playing " are arranged among the area E T.In the example shown in the accompanying drawing 10, pre-determine which kind of broadcast Limit Type of use corresponding to adding the position (position in record-header) that is suitable for the time limit data of playing Limit Type.
Therefore, will be respectively the expression data that mustn't play the time limit, be suitable for the time limit of playing Limit Type A and play Limit Type at last join in the content-data, and under aforesaid copy restriction with this content data recording to recording medium such as CD in.The content-data that is recorded in thus in the CD can be issued to the final user.Interchangeablely be such as the transmission of the Internet this content-data to be sent to the final user by communication network.
Wish to represent to use the data in the time limit of playing Limit Type to join in the content-data to guarantee just in time selling CD or protection content-data provider can be owing to the copy of having made many content-datas in the predetermined time limit loses his deserved profit in that day that publishes and distributes.、
Accompanying drawing 11 has been explained the distribution example that has added the content-data of following data therein: the data of Limit Type and the data that expression is suitable for the time limit of playing Limit Type are play in expression.Still in this example, will play the restricted type data and be suitable among the record-header HD of content-data that the time limit of playing Limit Type joins document form.
As shown in the accompanying drawing 11, with the 8 copy Limit Types of having described are similar with reference to the accompanying drawings, record-header HD comprises that first Close Date in the time limit area E D1, second that plays Limit Type zone PL1, the first suitable broadcast Limit Type plays Close Date in time limit area E D2 and the 3rd broadcast Limit Type zone PL3 that Limit Type zone PL2, second is suitable for the broadcast Limit Type.
In the example shown in the accompanying drawing 11, play the data that have been provided with among the PL1 of Limit Type zone by the specified broadcast Limit Type of content-data provider first.Playing Limit Type comprises predetermined a kind of such as " forbidding playing ", " only playing once ", " playing nearly 5 times ", " freely playing " etc.
Be suitable for to play to be provided with among Close Date in the time limit area E D1 of Limit Type first and be used for being applied in first Close Date of playing the time limit of the set broadcast Limit Type (first plays Limit Type) of Limit Type zone PL1.In the example shown in the accompanying drawing 11, first Close Date in time limit that is suitable for the broadcast Limit Type was on August 31st, 2000.Time limit before 31 days Augusts in 2000 is to be applicable to that first plays the time limit of Limit Type.
In the example of accompanying drawing 11, in the first broadcast Limit Type zone PL1, be provided with predetermined broadcast Limit Type such as " forbidding playing ", " only playing once ", " play and reach 5 times ", " freely playing " etc.
In Close Date in the time limit area E D2 of the second suitable broadcast Limit Type, be provided with the Close Date that is used for using in the time limit of the set broadcast Limit Type (second plays Limit Type) of the second broadcast Limit Type zone PL2.Second Close Date in time limit that is suitable for the broadcast Limit Type for example was on September 30th, 2000.In the example shown in the accompanying drawing 11, second time limit that is suitable for the broadcast Limit Type started from next day in 1 day September in 2000 of the time limit end of the first suitable broadcast Limit Type and ended at September 30 in 2000.
In the 3rd broadcast Limit Type zone PL3, be provided with predetermined broadcast Limit Type such as " forbidding playing ", " only playing once ", " play and reach 5 times ", " freely playing " etc.In the example shown in the accompanying drawing 11, set data representation is play Limit Type at last in the 3rd broadcast Limit Type zone PL3.
In addition, still in accompanying drawing 11, indication is play the data of Limit Type and is indicated the data that are suitable for the time limit of playing Limit Type to join in the content-data.Content-data can be joined recording medium such as in the CD so that be issued to the final user, perhaps such as the transmission of the Internet it is sent to the final user by communication network.Therefore, also by giving the data that add expression broadcast Limit Type in the content-data, can make neatly each content-data provider each other or every kind of content-data broadcast Limit Type each other inequality.
[player of controls playing restriction therein]
The content-data player of playing the content-data that has added following data is therein then described: the time limit data of the 10 suitable broadcast Limit Types of having described or the time limit data of the 11 suitable broadcast Limit Types of having described with reference to the accompanying drawings with reference to the accompanying drawings as mentioned as mentioned.Suppose that at this content data recording is in CD.
With reference now to accompanying drawing 12,, is depicted as content-data player with formal specification content data from CD 550 of calcspar.Generally represent the content-data player with reference number 500.It should be noted, above 10 and 11 described the content-data in time limit of having added suitable broadcast Limit Type therein etc. with reference to the accompanying drawings.
When being encased in CD 550 in the player 500, the latter's controller 520 control optical pickups 501 project a laser onto on the CD 550.The reflected light that optical pickup 501 detects from CD 550.Controller 520 control Spindle Motors 502 are so that for example with constant linear velocity (LCV) rotary CD 550.
Optical pickup 501 comprises optical system, gearing photoelectric detector etc., and this optical system comprises lasing light emitter such as semiconductor laser, beam splitter, object lens etc., and gearing drives object lens on focusing and tracking direction.Optical pickup 501 detects the light that returns from CD 550 from lasing light emitter emission laser by photoelectric detector, the reflected light that is detected is converted to electric signal, and the signal conveys that will export from photoelectric detector is in RF circuit 503.
RF circuit 503 produces and reads RF signal and servocontrol error signal such as tracking error signal and focus error signal etc.The servo error signal that is produced thus is transported to servo circuit 504, will reads the RF signal conveys simultaneously in demodulator circuit 505.
Servo circuit 504 based on from the servosignal of RF circuit 503 control Spindle Motor 502 with constant linear velocity (LCV) rotary CD 550, and go back laser scanning the track on CD 550 of rotary optical pick-up head 501 to use bundle point of a size suitable.
Player 500 also has the control module 524 of key operation.When the user imported play instructions by the control module 524 of key operation, each parts of system controller (being called " controller " hereinafter simply) 520 controls playing devices 500 were also play the content-data that is read by optical pickup 501 from CD 550.
More particularly, controller 520 moves to a position on CD 550 with optical pickup 501, has write down it and instructed the file of playing (content-data) on this position.Describe as preamble, project a laser onto on the CD 550, by the back light of the detection of the photoelectric detector in optical pickup 501 from CD 550, and be converted to electric signal by photoelectric detector, and the electric signal that will be gathered thus is transported to the RF circuit 503 from photoelectric detector as output signal.
As indicated above, RF circuit 503 to be from being used to play the RF signal of the content-data that comprises record-header from producing the signal of optical pickup 501, and will read the RF signal conveys to demodulator circuit 505.Receive the control signal be used to start demodulation in the slave controller 520,505 pairs of content-datas of demodulator circuit from RF circuit 503 carry out demodulation and thus institute's demodulated data be transported to ECC demoder 506.
ECC demoder 506 is proofreaied and correct the error from the content-data of demodulator circuit 505, and the error content-data of being proofreaied and correct is transported to plays restricted information separation circuit 507.Play restricted information separation circuit 507 from the record-header HD of the content-data carried, separate and extract play restricted information such as be suitable for the time limit data of playing Limit Type, for the unique identification information of content-data such as ISRC, and with the data delivery extracted in controller 520.
As shown in the accompanying drawing 12, controller 520 has been connected to time holding circuit 521 and play count storer 522.Similar with the time holding circuit 421 in register 400, time holding circuit 521 has the function of calendar to keep current date, the same day in this week and current time the impossible user's change by player of these information.
The identification information of the content-data that play count storer 522 management is play by player 500 and the number of times (play count) of broadcast, the user by player can not change (increase, change or deletion) these information.That is, play count storer 522 is equivalent to the copy count storer 422 in register 400.Play count storer 522 management broadcasting times, and copy count storer 422 management copy number of times, but they manage the number of times that uses content-data in an identical manner.
Whether controller 520 might based on the same day of the same day that comes from time holding circuit 521 or the time of coming from holding circuit 521 with from definite broadcast of the information of play count storer 522.When controller 520 determine to play may the time, its controls playing control circuit 508 is to output to the outside by lead-out terminal 509 with the content-data of institute's demodulation.
When content-data was determined to play, controller 520 controls playing control circuits 508 exported the content-data of institute's demodulation for any circuit downstream level of Play Control circuit 508.Therefore, can the controls playing restriction in player based on the broadcast restricted information among the record-header HD that joins content-data.
As shown in the accompanying drawing 10, when in player 500 is play record-header HD therein, having added the content-data of time limit data of suitable broadcast Limit Type, carry out play operation with logging program after the register shown in accompanying drawing 6 and 7 the samely and limit with controls playing.
More particularly, when playing at the content-data shown in the accompanying drawing 10, controller 520 visit of player 500 such as being suitable for the time limit data of playing Limit Type etc., is visited the same day (that day of broadcast) of being preserved by time holding circuit 521 from the broadcast restricted information of playing restricted information separation circuit 507 then.
The time limit data of the suitable broadcast Limit Type that controller 520 is visited based on itself and determined whether mustn't play in the time limit same day on same day, controller 520 by form by LCD and be formed on display unit 523 on the player 500 to notify the user to play impossible, and withdraw from the program of play content data.
Definite same day not in the time mustn't playing in the time limit, controller 520 determines whether be suitable in the time limit of playing Limit Type A the same day.When controller 520 is determined to be suitable for the same day in the time limit of playing Limit Type A, it is based on from the data of content-data identification information visit in play count storer 522 of playing restricted information separation circuit 507, and has determined whether to surpass the broadcasting time of the content-data that will play.
When determine surpassing broadcasting time, controller 520 controls playing control circuits 508 are not carried the content-data of institute's demodulation, and play by display unit 523 untill further notice users impossible.Then, controller 520 withdraws from the program of play content data.
When being no more than dialling of the content-data that will play and putting number of times, controller 520 controls playing control circuits 508 are with the content-data of output institute demodulation.In this case, controller 520 makes dialling in play count storer 522 put number of times increase by 1 and withdraws from the content-data playing program.
Be suitable on the same day after the time limit of broadcast Limit Type A, controller 520 is play according to the last restricted type data limit of playing.That is,, unrestrictedly play this content when last broadcast Limit Type is " when freely playing ".
When last broadcast Limit Type limited broadcasting time, controller 520 was visited from the information of play count storer 522 and is made its play content data reach the number of times that is limited.When last broadcast Limit Type is " forbid play ", play content data not.Therefore, broadcast restriction that can the control content data.
When having added expression among the record-header HD that plays at it when playing the data of Limit Type and being suitable for the content-data of the time limit data of playing Limit Type, controller 520 as the recording process in the register as shown in the accompanying drawing 9 the ground controls playing operate broadcast with the limiting content data.
More particularly, when playing at the content-data shown in the accompanying drawing 11, at first controller 520 visits of player 500 are included in from the expression in the broadcast restricted information of playing restricted information separation circuit 507 and play the data of Limit Type and about being suitable for the data in the time limit of playing Limit Type, visit the same day (that day of broadcast) of being preserved by time holding circuit 521 then.
Controller 520 determines whether be suitable in the time limit of playing Limit Type first the same day.When determining that be that controller 520 is play the restriction of Limit Type controls playing according to first when first is suitable in the time limit of playing Limit Type the same day.When determining the same day not when first is suitable in the time limit of playing Limit Type, controller 520 determines whether be suitable in the time limit of playing Limit Type second the same day.When determining the same day when second is suitable in the time limit of playing Limit Type, controller 520 is play the restriction of Limit Type controls playing according to second.
When determining the same day not when second is suitable in the time limit of playing Limit Type, controller 520 is play Limit Type (the promptly last Limit Type of playing) controls playing restriction according to the 3rd.
Therefore, can limit with the same ground of content-data copy restriction control content data playback.That is, content-data is play restriction permission protection content-data provider and is not lost his deserved profit.
In the embodiment that plays restriction control, play the content-data that is recorded in CD.Yet the present invention is not limited to this control that content-data is play restriction.For example, in the personal computer that the content-data provide such as the Internet by communication network is provided etc., player 500 is the same as the aforementioned can controls playing restriction (export-restriction) according to the broadcast restricted information in the record-header that is arranged on content-data.
For example, in receiver that is called IRD or STB (set top box) etc., this receiver will output to external device (ED) such as loudspeaker or monitoring receiver by the content-data that broadcast medium provides such as digital satellite broadcasting, player 500 equally can controls playing restriction (export-restriction) according to the broadcast restricted information in the record-header that is arranged on content-data as the aforementioned.
Play Limit Type and be not limited to aforesaid broadcast Limit Type, except above-mentioned broadcast Limit Type, can also use other various broadcast Limit Types.For example, except above-mentioned number of times such as " 1 " and " 5 ", can provide respectively broadcasting time suitably to be restricted to " 2 ", " 3 ", " 4 " ..., the broadcast Limit Type.
In addition, in aforesaid broadcast restriction control, when having determined the last broadcast Limit Type of all content-datas, need not play among the PL3 of Limit Type zone any data are set at last broadcast Limit Type area E T and the 3rd.Be suitable for the last Limit Type of playing during the time limit passing through, controls playing restriction in a predetermined manner, such as forbid that content-data is play, free play content data or the number of times that content-data is play is set.
For aforesaid broadcast restriction control, can provide the broadcast Limit Type of only once playing Limit Type or surpassing twice.In this case, predetermined broadcast Limit Type is assigned to for example each time limit in the example of accompanying drawing 10, and the data that will represent the broadcast Limit Type in each time limit simultaneously join in the content-data in the example of accompanying drawing 11.
Providing many (such as two, three, four ...) be suitable under the situation in the time limit of playing Limit Type, many broadcast Limit Types can be assigned to for first time limit separately, and the data that expression can be play simultaneously Limit Type join each second and the time limit subsequently in.
Interchangeablely be, providing many (such as two, three, four,) be suitable under the situation of playing the Limit Type time limit, can be assigned to for first time limit separately with playing Limit Type, and simultaneously as the example as shown in the accompanying drawing 10, will play Limit Type be assigned in advance second and subsequently time limit in each time limit in.
Under the situation that many suitable broadcast Limit Type time limits are provided as indicated above, for a content-data, can use the time limit of the broadcast Limit Type that correspondingly is assigned to the position that it added therein in advance together and will play the restricted type data adding time limit wherein.Can freely determine the position and the position in the time limit of the data that add expression broadcast Limit Type in the time limit of the Limit Type of appointment broadcast in advance therein.
In the example shown in accompanying drawing 10 and 11, the data of the broadcast Limit Type that expression is last join in the content-data respectively.Yet the present invention is not limited to this set.For example, for all players, be under the situation of " freely playing " or " mustn't play " pre-determining the broadcast Limit Type, will not represent that the data of playing Limit Type at last join in any content-data.
In other words, for all players, can determine to play at last Limit Type uniformly.Can set in advance the last broadcast Limit Type of each player.For example, content-based data beacon information etc. can make last broadcast Limit Type along with each content-data that will copy is differing from each other.
The time limit data and the suitable time limit data both who plays Limit Type that are suitable for the copy Limit Type can join in the record-header of content-data, perhaps the data and the sign of expression copy Limit Type can be applicable to that these two kinds of data of the data in the time limit of playing Limit Type all join in the record-header of content-data.

As 13 situations about having described with reference to the accompanying drawings, the content-data that has added do not pay the time limit data and the time limit data of paying in its record-header HD is input in the register shown in the accompanying drawing 14 600 by entry terminal 401 and is transported in the additional information separation circuit 601.
Note, the content-data of carrying register 600 from the content-data player, be connected to communication network such as the Internet and the user terminal by communication network received content data such as personal computer or the digital satellite broadcast receiver of content-data is provided, this content-data player is content data from the CD that has write down content-data therein.
Additional information separation circuit 601 is used for separating and extracting as pay the bill restricted information such as the time limit data of not paying the time limit zone NP that do not paying, paying time limit data in regional PY of due time limit and the content-data beacon information among the record-header HD at content-data required as shown in the accompanying drawing 13 from content-data, and the data delivery that will be separated thus is transported to content-data in the encrypted circuit 602 in controller 420 simultaneously.
For example slave controller 420 is given encrypted circuit 602 conveying encryption keys and the content-data that is recorded in the CD is encrypted to prevent that content-data from unlawfully being used.Encrypted circuit 602 flows to record control circuit 403 with encrypted content-data.
On the other hand, carry the time limit data of not paying as indicated above, paying time limit data, content-data beacon information etc. for controller 420, and it manage these data.When from keyboard operation control module 424 conveying recording instructions, the date on the same day that controller 420 visits are kept by time holding circuit 421 is also detected the same day (that day of record) of the content-data that will write down.
Controller 420 determines that the same day are whether in the time limit of not paying, in the time limit of paying or after having passed through the paying time limit.When the same day was in the time limit of not paying, controller 420 carried control signal will flow to combiner circuit 404 from the content-data of encrypted circuit 602 for record control circuit 403.
Simultaneously, controller 420 control additional information generation circuit 603 to be to produce the restricted information of paying the bill that will join in the content-data that will be recorded in the CD such as the time limit data of not paying, the time limit data of paying etc., control simultaneously combiner circuit 404, ECC scrambler 406, record modulation circuit 407 and writing circuit 408 with this content data recording to CD.
Therefore, will be transported in the combiner circuit 404, in combiner circuit 404, it is arranged in the precalculated position of record-header HD of content-data at the restricted information of paying the bill that additional information generation circuit 603 is produced.Be transported in the CD 650 by ECC scrambler 406, record modulation circuit 407, writing circuit 408 and optical pickup 409 content-data that will encrypt and that in its record-header HD, added its new restricted information of paying the bill.
In the time of in paying the time limit by time holding circuit 421 on same day of determining to be preserved, controller 420 reads in the payment in advance information in the memory card 660 that is inserted in the card reader 604 in the present embodiment, and determine whether and to pay the bill promptly, whether the remaining sum on user's account is enough.When paying the bill possibility, controller 420 is controlled at each circuit that the downstream provided of record control circuit 403 so that it can be with content data recording in CD 650.
Yet, when the same day of being preserved by time holding circuit 421 was to pay in the time limit but Sorry, your ticket has not enough value on the account the user when enough coming defrayment, perhaps when memory card 660 itself was not inserted in the appropriate location of card reader 604, controller 420 determines to pay the bill and controlling recording control circuit 403 does not output to this content-data in the combiner circuit 404.That is, controller 420 makes it can not be with this content data recording in CD 650.In this case, controller 420 notifies the user can not copy this content-data by display unit 423.
In that day of the same day or record is in the paying time limit as above the time, only pay the bill may the time just can copy this content-data.In the time can not paying the bill, forbid copying this content-data.It should be noted, be when paying after the time limit on the same day, the copy restriction or the restriction of paying the bill be scheduled at the 3rd embodiment middle controller 420.In the register 600 that is included in the 3rd embodiment, all unify to forbid copy for any situation.
Notice that except on the same day being forbids after the time limit of paying the time the copy, the copy that makes controller 420 can also freely copy or be scheduled to limits the restriction of control ratio as the number of times that copies.Should also be noted that, restriction for the copy number of times, controller 420 determines based on the information in copy count storer 422 whether copy is possible, and when having copied content-data, be updated in the copy count in the copy count storer 422, as in the register 400 of aforesaid first and second embodiment.
On the same day was when paying after the time limit, the restriction control of paying the bill that controller 420 can be scheduled to.More particularly, can make controller 420 allow this content-data of copy after being in the time limit of paying and can pay predetermined money the time on same day, and in the time can not paying the money of being scheduled to, forbid copying.
Note, for example in register 600, pre-determine the money of being kept accounts.Certainly, the data of the money that expression can also be kept accounts join among the record-header HD of content-data, this content-data is flowed to register 600, and by the money information of additional information separation circuit 601 from extraction record keeping the content-data of register 600, the money information of usage billing when paying the bill thus.
Register 600 in the 3rd embodiment has aforesaid communication I/F605.By the data of communication I/F605 from the money that expression can be provided on the server of content-data provider keep accounts.
Still in the 3rd embodiment, can specify by following mode having passed through the copy Limit Type applicatory after the time limit of paying or the Limit Type of paying the bill: will copy at last among the record-header HD that the Limit Type data or the Limit Type data of paying the bill at last join content-data and this data are provided with this content-data.
[being included in the data recording of the register among the 3rd embodiment]
Then, be described in above with reference to the accompanying drawings the recording operation that carries out in the register of having described in 14 600.Accompanying drawing 15 is depicted as the operations flows of carrying out in record in register 600 (restriction record) process.When input recording instruction from the keyboard operation control module 424 that register 600, is provided, by entry terminal 401 content-data is transported in the register 600, the controller 420 of register 600 is as hereinafter with reference to operating the operation of the flow chart description as shown in the accompanying drawing 15.
At first, in step S301, controller 420 is visited the restricted information of paying the bill from aforesaid additional information separation circuit 601, promptly visits the time limit data of not paying, the time limit data of paying and content-data beacon information.Then in step S302, controller 420 is visited the same day of being preserved by time holding circuit 421.
In step S303, controller 420 is based on determined that the same day was whether in the time limit of not paying the same day of not paying the time limit data and having visited in the restricted information of paying the bill of having visited in step S302 in step S301.
When determining that in step S303 be in the time limit of not paying the time same day, controller 420 proceeds among the step S304, it allows the copied content data in step S304, controlling recording control circuit 403 is transported to (that is, the various parts of controlling recording device 600 are to carry out recording operation) in the combiner circuit 404 with encrypted content-data.Then, controller 420 proceeds among the step S305, in step S305 it make register 600 with content data recording in CD 650.After this, in step S306, controller 420 is waited for up to finishing the copied content data.When copy was finished, controller withdrawed from the program shown in the accompanying drawing 15.
When determining that in step S303 the same day is not in the time limit of not paying, controller 420 proceeds among the step S307, and it is based on determined that the same day was whether in the time limit of paying the same day of paying the bill restricted information and having visited of having visited in step S301 in step S302 in step S307.
When determining that in step S307 be that controller 420 proceeds among the step S308 when paying in the time limit same day, it for example notifies the user only just can copy this content-data by defrayment by display unit 423 in step S308.In step S308, controller 420 control display units 423 are with display message, such as " the payment reasonable expense allows copy.Specific prepaid card is inserted in the card reader ".
In step S309, the remaining sum of the payment in advance in the memory card 660 (prepaid card etc.) of controller 420 inspection records in being inserted in card reader 604 also determines whether and can pay the bill.When in step S309, determining to pay the bill possibility, controller 420 proceeds to step S310, it allows copy in step S310, and controlling recording control circuit 403 is transported to (that is, the parts of controlling recording device 600 carry out recording operation) in the combiner circuit 404 with encrypted content-data.Then, in step S311, controller 420 make register 600 with content data recording in CD 650.
In step S312, controller 420 is waited for and being finished up to the record of content-data.When record is finished, controller 420 proceeds to step S313, it is paid the bill by deducting the expense that is used to copy in the payment in advance (remaining sum) in the prepaid card from be inserted in card reader 604 (memory card) 660 in step S313, and withdraws from the program in accompanying drawing 15.
Note, in the time of in step S313, can not successfully paying the bill, for example, when prepaid card (memory card) 660 takes out from card reader 604, up to this pay the bill complete successfully before paying the bill operation in step S313 can not finish.Can not the copied content data before not paying.
When in step S309, determining to pay the bill, content-data is not transported in the combiner circuit 404 at the 3rd embodiment middle controller 420 controlling recording control circuits 403, in step S315, forbid the copied content data thus.
In the operation of step S315, controller 420 shows such as " not paying the bill by control display unit 423.Insertion has the prepaid card of the payment in advance of enough remaining sums " thus and so on the message informing user owing to can not successfully pay the bill and can not copy.
When determining that in step S307 the same day is not in the time limit of payment, proceed to step S314 at the 3rd embodiment middle controller 420, it controls the copy restriction in a predetermined manner in step S314.Owing to forbid copy after having passed through the time limit of payment, controller 420 controlling recording control circuits 403 are forbidden the recorded content data thus content-data is transported in the combiner circuit 404 in the 3rd embodiment.
In step S314, controller 420 shows such as " having passed through the time limit that can copy by control display unit 423.Do not allow copy " and so on the message informing user can not the copied content data.
As indicated above; add in the content-data do not pay time limit and paying time limit by giving; in the time limit of the certain-length of starting selling, allow free this content-data of copy for the purpose of propagating; in order not pay that the universal of content-data is interfered after the time limit but protect content-data provider not lose its deserved profit and prevent having passed through, just allow the suitable expense of payment can copy this content-data.
Note, in the 3rd embodiment, provide one not pay time limit and a paying time limit as shown in Figure 13, but the present invention is not limited to this set.For example, for only when having paid the expense of being scheduled to, just allowing the copied content data having passed through after the predetermined time limit of not paying, so the time limit data of will not paying join in the content-data.Even, just can use do not pay time limit and paying time limit: passed through after the time limit of not paying as long as when the copied content data, will pay predetermined expense by carry out such control in the register side only by joining the time limit data of not paying in the content-data.
Under the situation that any time limit of not paying is not provided, only the time limit data of paying should be joined in the content-data.Not paying any expense (freely) after the paying time limit only being provided and having passed through the paying time limit just allows under the copied content data conditions, even only by joining under the paying time limit data conditions in the content-data, by allow this control of gratis copied content data in the register side, after having passed through the paying time limit, can use the pay time limit and the time limit copied content data of not paying.
Just allow under the situation of copied content when after the paying time limit only being provided and having passed through the time limit of paying, only having paid predetermined expense, only will join in this content-data about the data in the time limit of paying.Just can be applied in two differing from each other aspect paying the bill and pay the time limits by carry out such control in the register side: pass through after the time limit of paying as long as the expense that just essential payment is scheduled to when the copied content data.It should be noted and can be provided in the aspect of paying the bill many paying time limits differing from each other.
In aforesaid the 3rd embodiment, implement to be included in and passed through the predetermined copy restriction control of forbidding any copy after the time limit of paying.That is, pre-determine the copy Limit Type that after last time limit of having passed through in the do not pay time limit and the time limit of paying, is suitable for, in register 600, automatically carry out copy restriction control corresponding to predetermined copy Limit Type.Yet the present invention is not limited to this set.
For example, can implement following this set: the data that will be illustrated in the copy Limit Type (copying Limit Type at last) that is suitable for after last time limit of having passed through in the do not pay time limit and the time limit of paying join in the content-data and based on join in the content-data restriction of last copy Limit Type control copy with passed through the deadline date, copied content data after the do not pay time limit or the time limit of paying.In this case, this device can be revised as and in additional information separation circuit 601, extract the last copy restricted type data that join in the content-data, and by the copy of controller 420 uses with the limiting content data.
Can use the Limit Type of paying the bill at last and substitute last copy Limit Type.Join in the content-data that will send by the unified Limit Type of paying the bill at last that pre-determines all registers maybe will represent to pay the bill the at last data of Limit Type, can control the copy restriction so that only when having paid the expense of being scheduled to, just allow the copied content data after the time limit that is suitable for the Limit Type of paying the bill at last having passed through.
This Limit Type of paying the bill at last can also be applicable to the data transmission method according to aforesaid first and second embodiment.That is, be applied in the last copy Limit Type area E T conduct shown in the accompanying drawing 1 and pay the bill the Limit Type zone at last after the time limit of having passed through the suitable Limit Type of paying the bill at last, only when having paid predetermined expense, just to allow the copied content data.
[playing restriction control]
The 3rd embodiment has described about copy restriction control.Yet, controls playing restriction similarly.More particularly, under application joins the do not pay time limit and the time limit play content data conditions of paying among the record-header HD of content-data as shown in Figure 13, can be in player the broadcast of control content data so that in the time limit of not paying, allow gratis play content data, and in the time limit of paying, only when having paid predetermined expense, just allow to play it.

Card reader 703 provides the purposes of paying the bill.It has and is used to hold the slot of memory card such as the so-called prepaid card with the payment in advance information that is recorded in wherein, reads money information or money information is written to wherein from be inserted in memory card wherein.
Communication I/F704 is connected to communication network such as the Internet with the terminal 705 that is connected to the I/F704 that communicates by letter with player 700.For example, I/F704 and terminal 705 allow player 700 that the information about paying the bill that for example provides by communication network is provided.
Corresponding parts in other parts of player 700 in accompanying drawing 16 and the player 500 in first and second embodiment shown in the accompanying drawing 12 are constructed similarly, therefore represent them with identical or similar Ref. No. in accompanying drawing 12.Therefore, explain them hereinafter no longer in detail.
The same with the player 500 in accompanying drawing 12, when the control module 524 that CD 750 is inserted in the player 700 and the user operates by operating key is imported play instructions, player 700 begins content data from CD 750, and the content-data that demodulation is read from CD 750 also flows to institute's demodulated data in the additional information separation circuit 701.
Additional information separation circuit 701 from the time limit zone NP that do not pay among record-header HD, separate and extract do not pay the time limit data with from due time limit zone PY, separates and extracts paying time limit data, this data delivery is transported to this content-data in the Play Control circuit 508 simultaneously to controller 520.
Controller 520 is to limit with the basic similarly mode controls playing of the mode in the register shown in the accompanying drawing 15 600.Promptly, do not pay the time limit data and the time limit data of paying that controller 520 visits are carried from additional information separation circuit 701, visit the same day of being preserved then, determine that thus the same day is whether in the determined time limit of not paying by the time limit data of not paying by time holding circuit 521.
When definite same day was in the time limit of not paying the time, controller 520 allows the play content data, controls playing control circuit 508 and decrypt circuit 702 will be being transported to from the content-data of additional information separation circuit 701 in the decrypt circuit 702, at decrypt circuit 702 it is decrypted, and with through the content-data of deciphering by lead-out terminal 509 outputs.
When definite same day was in the time limit of not paying, controller 520 determined that the same day are whether in the time limit of paying.On definite same day was when paying in the time limit, controller 520 notifies the user only just to allow the play content data when having paid suitable expense, and the remaining sum of the payment in advance that is write down in the memory card 730 of inspection record in being inserted in card reader 703 is to determine whether and may pay the bill.
When controller 520 determines to pay the bill possibility, it allows the play content data, ground as indicated above controls playing control circuit 508 and decrypt circuit 702 will be being transported to from the content-data of additional information separation circuit 701 in the decrypt circuit 702, at decrypt circuit 702 it is decrypted, and with through the content-data of deciphering by lead-out terminal 509 outputs.
Causing because the payment in advance remaining sum is not enough or memory card 730 suitably is not inserted in the card reader 703 can not pay the bill the time, controller 520 controls playing control circuits 508 are not transported to content-data in the decrypt circuit 702, forbid the play content data thus.
In the time of in not paying the time limit, that is, determine that be after the time limit of paying the time same day, the broadcast restriction that controller 520 is scheduled on definite same day.In the present embodiment, the broadcast restriction of being scheduled to comprises forbids playing, freely plays, limits broadcasting time etc.
Notice that for the number of times that restriction is play, the data of controller 520 visits in play count storer 522 are to check the play count of the content-data that will play.Only controller 520 just allows the play content data and makes the broadcasting time of the content-data in play count storer 522 increase by 1 when playing possibility.In this case, from the record-header HD of this content-data, extract the beacon information of the content-data that will play, and it is flowed to controller 520 by additional information separation circuit 701.Therefore, can use the content-data beacon information.
Join content-data by do not pay time limit and the time limit of paying that will be used for that content-data plays as indicated above, the same with the control of copy restriction can the controls playing restriction.
Attention, still in playing restriction control, for only just allow the play content data when having paid predetermined expense after having passed through the time limit of being scheduled to not pay, the time limit data of will not paying join in the content-data.Even only use the time limit data of not paying join in the content-data,, can use the time limit of not paying so that passed through after the time limit of not paying by carrying out such control as long as play the expense that the just essential payment of this content-data is scheduled in the player side.
Do not pay during the time limit providing any, only the time limit data of paying should be joined in the content-data.Just allow under the copied content data conditions only providing the time limit of paying not pay any expense (freely), even only by joining under the paying time limit data conditions in the content-data, can only use do not pay time limit and paying time limit by carry out such control in the player side, promptly whenever the play content data user does not pay the bill after having passed through the paying time limit.
Provide one pay the time limit and at any time the play content data all should pay under the situation of predetermined expense, the time limit data of only will paying join in this content-data.By carrying out such control: passed through after the time limit of paying as long as when the copied content data, will pay predetermined expense, can be applied in the aspect of paying the bill two paying time limits differing from each other in the player side.It should be noted and can be provided in the aspect of paying the bill many paying time limits differing from each other.
Be in addition in aforesaid broadcast restriction control, pre-determine the broadcast Limit Type that after last time limit of having passed through in the do not pay time limit and the time limit of paying, is suitable for, and in player 700 according to playing Limit Type controls playing restriction automatically.Yet the present invention is not limited to this set.
The data of suitable broadcast Limit Type (playing Limit Type at last) join in the content-data and have passed through this content-data of broadcast after the deadline date after will being illustrated in last time limit of having passed through in do not pay time limit and paying time limit, can also play Data Control broadcast Limit Type and that join in the content-data at last based on expression and limit.In this case, in additional information separation circuit 701, should extract the last broadcast Limit Type data that join in the content-data and use by controller 520 and to limit with controls playing.
Can use the Limit Type of paying the bill at last and substitute the last Limit Type of playing.Join in the content-data by the unified data that pre-determine pay the bill the at last Limit Type or the Limit Type of will paying the bill at last of all players, can controls playing limit so that after the time limit of having passed through the suitable Limit Type of paying the bill at last, only when having paid predetermined expense, just allow the play content data.
This Limit Type of paying the bill at last can also be applicable to the data transmission method in first and second embodiment respectively.That is, be applied in the last broadcast Limit Type area E T shown in the accompanying drawing 10 and the 3rd shown in the accompanying drawing 11 play Limit Type zone PL3 as the Limit Type zone of paying the bill at last only when having paid the expense of being scheduled to, just to allow the play content data passed through the deadline date after.
