Content utilizes the purposes of descriptor to be, for this program, is configured (sending) under the situation of record about the control information of savings (record) or output.Its meaning is expression, field (Off イ one Le De) at 1 bit of digital_recording_control_mode (digital copy mode bit) is under the situation of " 1 ", even the digital_recording_control_data of digital copy illustrated in fig. 5 control descriptor also can carry out record as " allowing the number restriction to duplicate " for " allowing duplicating of a generation ".Under the situation for " 0 ", can not carry out record as " allowing the number restriction to duplicate ".
In addition, content is utilized descriptor, at this program is must dispose (sending) under the situation of object of output protection.The meaning of this output protection is, uses content to utilize the output protection bit (encryption_mode) of descriptor, for the high speed digital interface output of the content of " allowing does not have duplicating of restriction condition ", implements protection.In other words, though when in the output of digital interface or to the duplicating of recording medium, encrypt, to the number of times that duplicates or do not limit from generation to generation.And in fact become impossible to the transmission again of the Internet.Be also referred to as " duplicating of attached output protection is free " or EPN (encryption plus non-assertion).
In addition, the digital copy control information of this program is " allow a generation duplicate ", and, not must dispose (sending) under the situation of object of " allowing the number restriction to duplicate ".
Fig. 4 is the example of record content that the expression content is utilized each field of descriptor.
In " descriptor_tag ", record and narrate the meaning content and utilize " 0xDE " of descriptor." among the descriptor_length, recording and narrating the descriptor length that content is utilized descriptor.In " digital_recording_control_mode ", be " allowing duplicating of a generation " in the digital copy control information, and, not that the situation of the object of " allowing the number restriction to duplicate " is recorded and narrated " 0 ".The digital copy control information is " allowing duplicating of a generation ", and is the situation record " 1 " of the object of " allowing the number restriction to duplicate ".
In " encryption_mode ", be " allowing duplicating of no restriction condition " in the digital copy control information, and the situation that output is implemented to protect to high speed digital interface is recorded and narrated " 0 ".
" retention_mode " meaning is temporarily to put aside control bit, " 0 " expression of recording and narrating is even " digital_recording_control_data " (digital copy control information) of digital copy control descriptor also can temporarily be put aside for " forbidding duplicating "." retention_state " meaning is the time of allowing temporary transient savings, and " 111 " expression of record can be put aside 1 hour 30 minutes.In addition, " image_constraint_token ", " retention_state ", " encryption_mode " are " 1 " when the state of acquiescence.
About each field,, with reference to Fig. 7 narration is arranged also later as the processing of receiver side.
Fig. 5 is the example of expression as the structure of one digital copy control descriptor of copy control information.Digital copy control descriptor, be for example by management information give portion 16 generate, additional, be accommodated among the PSI (as an example PMT etc.) of MPEGTS or the SI and the information that is sent out.
Digital copy control descriptor represents, information is from generation to generation duplicated in the field control of 2 bits by " digital_recording_control_data " (digital copy control information).
Fig. 6 is the example of expression digital copy control information.The digital copy control information allows duplicating of no restriction condition for expression under the situation of " 00 ", be the content of expression under the situation of " 01 " based on the definition of broadcast unit, for expression under the situation of " 10 " allows duplicating of a generation, for expression under the situation of " 11 " is forbidden duplicating.In addition, though so-called to allow duplicating of a generation be that expression can be write down the play signal that (duplicating of the first generation) receives, reproducible (copy) play signal not after writing down.
The content of Fig. 3 and Fig. 4 is utilized descriptor to be also referred to as and is duplicated the number restricted information, and the digital copy control information of Fig. 5 and Fig. 6 is also referred to as the generation limit information of duplicating.
For with from dispensing device 1 output, the specific example of the processing of the receiving trap 3 that the copy control information that illustrate in Fig. 3～Fig. 6 is correlated with describes.
Fig. 7 is each field of descriptor of an example of processing expression utilizes to(for) the content in the receiving trap 3.
When " descriptor_tag " is " 0xDE ", judge that this descriptor is that content is utilized descriptor.Utilize the descriptor length of descriptor by " descriptor_length " judgement content.When " digital_recording_control_mode " was " 1 ", under the situation of digital copy control information for " allowing duplicating of a generation ", judgement was the object of " allowing the number restriction to duplicate ".During for " 0 ", under the situation of digital copy control information, judge it is not the object of " allowing the number restriction to duplicate " for " allowing duplicating of a generation ".About " image_constraint_token ", no matter import the restriction what kind of value all is judged as the resolution of not carrying out signal of video signal output.About " retention_mode ", all be judged as and temporarily put aside no matter import which type of value.About " retention_state ", it is 1 hour 30 minutes no matter import the allowed time which type of value all is judged as temporary transient savings.When " encryption_mode " is " 1 ", under the situation of digital copy control information for " allowing duplicating of no restriction condition ", do not implement protection when being judged as high speed digital interface output.During for " 0 ", under the situation of digital copy control information for " allowing duplicating of no restriction condition ", implement protection when being judged as high speed digital interface output.
In addition, do not having configuration (sending) content to utilize under the situation of descriptor owing to certain reason, it is following value that each field can be interpreted as.digital_recording_control_mode＝“1”，image_constraint_token＝“1”，retention_mode＝“0”，retention_state＝“111”，encryption_mode＝“1”。
Fig. 9 is the example that expression receiving trap 3 utilizes the control of copy control information savings (record) programme content.
Content shown in Figure 9 is, for example when the savings programme content, the digital_recording_control_data of digital copy control descriptor is under the situation of " 10 ", " allowing duplicating of a generation ", and the copy control information on the recording medium was put aside as " forbidding duplicating " again.But, be under the situation of " 1 " at digital_recording_control_mode, put aside as " allowing the number restriction to duplicate ".In addition, under the situation about putting aside with " forbidding duplicating again ", also can not change the value of the digital_recording_control_data of digital copy control descriptor.
In addition, the digital_recording_control_data of digital copy control descriptor is under the situation of " 10 ", " allowing duplicating of a generation ", can not generate a plurality of duplicating.But, be purpose with the backup except the savings in the zone that the user can not visit.In addition, above-mentioned restriction, the thing for the acceptance division that makes each broadcast is born has under a plurality of situations at the acceptance division of playing, and makes the acceptance division of each broadcast bear above-mentioned restriction.
About allowing the number restriction to duplicate, the programme content from being put aside as " allowing the number restriction to duplicate " can generate N and duplicate.The value of N for example can be to be benchmark with the specification.Generating the situation of duplicating via high speed digital interface output is, by using locomotive function etc., can determine also can duplicate under the situation of the number that duplicates that generates.For example, being recognition interface to be that IEEE1394, output destination are the situation corresponding to the device of DTCP specification.In addition, the state that copies as " forbidding duplicating again " or be equal to therewith of generation.
In addition, under the situation of the programme content that reproduction and output conduct " allowing number to limit duplicates " quilt is put aside, at high speed digital interface, carry out by the processing of the No More Copies of DTCP (Digital Transmission ContentProtection) the regulation line output of going forward side by side.About analog image output and digital audio output, can export as " allowing duplicating of a generation ".
At recording medium is under the situation of removable recording medium, and other restriction is arranged on the basis of Fig. 9.Digital recording about programme content to removable recording medium, in the digital recording of the digital recording of TV, data, services or voice service, when the digital_recording_control_data that receives digital copy control descriptor writes down for the programme content of " 10 " and " allowing duplicating of a generation ", even do not allow duplicating more than 3 (for example, when line item is gone forward side by side in the reception broadcast, can not in the recording medium more than 3, write down simultaneously) about the content first generation that receives yet.This value (being exemplified as more than 3) can be benchmark with the specification also for example.In addition, it is a plurality of duplicating of the identical generation of record format to be generated.But, be purpose with the backup except the digital recording in the zone that the user can not visit.In addition, the record restriction to digital recording medium is born the acceptance division of each broadcast, when the acceptance division of playing has under a plurality of situations, makes the acceptance division of each broadcast bear above-mentioned restriction.Under receiving trap is equipped with situation with the not corresponding recording mode of digital_recording_control_mode, copy_control_type about digital copy control descriptor is " 01 ", and, digital_recording_control_data is the programme content of " 10 ", carries out digital recording no matter content utilizes the value of the digital_recording_control_mode of descriptor why to be worth all according to the processing of " allowing duplicating of a generation ".

11 forbid duplicating (Copy-never)
Can not duplicate (No-more-copies) again behind 01 video recording
10 only can write down a generation (Copy-one-generation)
00 can duplicate (Copy-free).
Reproducible number information is to specify with the integer more than 0, and appointment can be duplicated several.In addition, duplicate and to exist data encrypted and be output the data of protection and do not have the encrypted data that also are not output protection in the numerical data that generational management information is " can duplicate ".
But Figure 12 is the example of preferred data structure of the recording medium 115 (for example removable hard disk) of expression installing/dismounting.The management area that 115 persons of being to use can not visit.Be kept at the management area by the key data that will be used for encrypting to digital data and be recorded in data recording area 302 and keep invisible.302 persons of being to use can visit the data recording area of inner data by the operation of stipulating.In 301, write down key data.In 302, write down the information regeneration data that are used to differentiate corresponding to the key information of each data of data recording area with the data of video-audio data or still image data etc.But in the recording medium 115 of such a installing/dismounting, also copy control information can be recorded in the management area blanketly.
Figure 13 is the synoptic diagram of an example of preferred data structure of representing the recording medium of Figure 12 with another form of expression.This recording medium is the recording medium (being also referred to as secure removable media) that can duplicate control.Duplicating in the control here comprises the management (be also referred to as and duplicate generational management, duplicate control from generation to generation, control is from generation to generation duplicated) of a plurality of management of duplicating (be also referred to as and duplicate number management, duplicate number control, number control is duplicated) and/or generation of duplicating.In a recording medium, have anti-tamper (anti-tamper) zone that normal areas that the user can visit and user can not visit concurrently.The confidential information of taking in anti-tamper zone under the situation that can confirm to authenticate with the authentication processing of the device that can handle this recording medium, becomes and can visit, and just can carry out the management of confidential information.The 301 corresponding anti-tamper zones, management area of Figure 12, data recording area 302 corresponding normal areas.
In the record reproducing device of in Figure 10, representing 100, but the recording medium 115 of installing/dismounting different with shown in Figure 12 and Figure 13, for example be might be by the improper recording medium of distorting about the management information and the programme information that duplicate control, or can not duplicate control recording medium (when with duplicate the recording medium of control at once not assert by specification etc.) situation under, when record is from numerical data that input terminal 101 is transfused in this recording medium 115 (non-safety record medium), it is No-more-copies that control part 111 makes the generational management information of duplicating of copy control information handling part 203, and reproducible number information is 0 to carry out record.
The picture display process of＜listing, program details, program search 〉
Consider that in the present embodiment the user uses a teleswitch or uses operating portion 110 (acceptance division and the operating portion 110 of general designation remote control are also referred to as operation inputting part), carries out the situation of recording schedule in record reproducing device 100.From the numerical data of input terminal 101 inputs for example is the digital broadcast signal.Under the situation that digital broadcast is recorded a video, utilize the electric program guide that generates based on the SI information that sends from broadcast office to carry out recording schedule, very effective on the convenience that improves the user, usually utilize electric program guide to carry out recording schedule mostly.
Utilize the digital_recording_control_mode information of descriptor to making content, perhaps an example of processing that is included in the electric program guide of the situation in the SI information for example about the information of duplicating control of answering a pair of with it describes.
Broadcast office is that the multiple content that is provided with utilizes descriptor or content to utilize the digital_recording_control_mode information of descriptor or about the SI information of the information of duplicating control of answering a pair of with it, sends numerical data in the video-audio data.This numerical data in input terminal 101 inputs is separated into video-audio data and SI information etc. by acceptance division 102.Based on the SI information (for example EIT) of separating by acceptance division 102, control part 111 shows electric program guide on picture.At this moment, content from be included in SI information is utilized the digital_recording_control_mode information of descriptor or will be duplicated generational management information and reproducible number information (below, be generically and collectively referred to as copy control information) about the information of duplicating control of answering a pair of with it and is included in the electric program guide.
Receiver 3 (record reproducing device 10) is according to above-mentioned＜copy control information〉like that the content of the copy control information that shows being judged of illustrating in the hurdle.Perhaps as in addition determination methods, the field of 1 bit of the digital_recording_control_data of digital copy control descriptor is " 0 ", and the descriptor that passes through that comprises in for example service describing table (ServiceDescription Table) of digital broadcast or the Event Information Table (Event Information Table) represents that this program is the situation of the free_CA_mode of charge/free for " 0 " of expression free, the generational management information of duplicating when judging record is " can duplicate ", field at 1 bit of digital_recording_control_data is " 1 ", and free_CA_mode is the situation of " 0 " of expression free, the generational management information of duplicating when judging record is " allowing the restriction number to duplicate ", field at 1 bit of digital_recording_control_data is " 1 ", and free_CA_mode is the situation of " 1 " of expression charge broadcast, and the generational management information of duplicating when judging record is " forbidding duplicating ".If this method, owing to be the information that in advance sends, so have the advantage that when electric program guide shows, can judge.
Figure 14 is an example that comprises the electric program guide of copy control information.The 1401st, the dateline on expression date, the 1402nd, expression moment hurdle constantly.It in the example of Figure 14 the example of the expression program guide of ordering from No. 19 PM5 points to PM7.The 1403rd, represent the broadcast scheduled program hurdle of the broadcast scheduled program of each broadcast office, distinguish by playing the schedule time.The 1404th, the expression user plays the program detail information hurdle of the program detail information of time on date, programm name and copy control information etc. by the channel of the program of telepilot or operating portion 110 selections.In the example of Figure 14,1404 the copy control information on program detail information hurdle is to duplicate from generation to generation that information and reproducible number information show as text line.But display packing also can show by text line, also can show (also is later on same about Figure 15) by the image of icon etc.In addition, copy control information also can just duplicate information from generation to generation, perhaps is reproducible number information, but the preferred reproducible number information (also is later on same about Figure 15) that shows.
In the example of Figure 14, displaying duplication control information in program detail information hurdle 1404, copy control information also can show in each program area of playing scheduled program hurdle 1403.Thus, in program guide,, also can discern copy control information even without program detail information hurdle 1404.
In addition, but under the situation of the record reproducing device 100 of the recording medium 115 of the compatible installing/dismounting that does not have a management area that the user can not visit, promptly, carry out under the situation of the record reproducing device 100 of the video recording of the medium of the non-correspondence of copyright administration, as shown in figure 18, the copy control information of the situation of the copy control information of the situation of 1404 demonstrations " to the video recording of the corresponding medium of copyright administration " and " to the video recording of the non-corresponding medium of copyright administration " on the program detail information hurdle.Thus, with regard to carrying out record reproducing device, also can improve user convenience to the video recording of the non-corresponding medium of copyright administration.
In the example of Figure 18, displaying duplication control information in program detail information hurdle 1404, but copy control information also can show in each program area of playing scheduled program hurdle 1403.Thus, in program guide,, also can discern copy control information even without program detail information hurdle 1404.
Next, content is utilized the digital_recording_control_mode information of descriptor, and perhaps an example of processing that is not included in the generation electric program guide of the situation in the SI information about the information of duplicating control of answering a pair of with it describes.The definite uniquely situation of control mode of duplicating that each broadcast office uses, for example, the program that certain broadcast partial seeding is put all is " allowing duplicating of a generation ", under the situation that " can duplicate a plurality of ", show the copy control information that this broadcast office adopts in each broadcast office hurdle on broadcast scheduled program hurdle 1403.
At this moment, but (promptly carry out under the situation of the record reproducing device 100 of the video recording of the non-corresponding medium of copyright administration) under the situation of the record reproducing device 100 of the recording medium 115 of the compatible installing/dismounting that does not have a management area that the user can not visit, copy control information under the copy control information under the situation of demonstration " to the video recording of the corresponding medium of copyright administration " and the situation of " to the video recording of the non-corresponding medium of copyright administration ".
In addition, what each broadcast office used duplicates under the not definite uniquely situation of control mode, duplicate in broadcast office side control program programm name the top or insert copy control information at last, when programming complete list, will comprise the programm name input program guide and the demonstration of this copy control information, and can point out the copy control information of this program thus to the user.And, but allow not have under the situation of record reproducing device 100 of recording medium 115 of installing/dismounting of the management area that the user can not visit (promptly carrying out under the situation of the record reproducing device 100 of the video recording of the non-corresponding medium of copyright administration), identification program names ahead or the copy control information that appends at last, copy control information under the copy control information under the situation of demonstration " to the video recording of the corresponding medium of copyright administration " and the situation of " to the video recording of the non-corresponding medium of copyright administration ".
Figure 15 person of being to use uses a teleswitch or an example of the program detail information picture when using the details of operating portion 110 display programs.The expression content is utilized the digital_recording_control_mode information of descriptor, perhaps is included in an example of the processing of the situation in the SI information about the information of duplicating control of answering a pair of with it.The numerical data that is input to input terminal 101 is separated into video-audio data and SI information etc. by acceptance division 102.Control part 111 is based on the SI information of being separated by acceptance division 102, display program detailed picture on picture.At this moment, the content from be included in SI information is utilized the digital_recording_control_mode information of descriptor, perhaps about the information of duplicating control of answering a pair of with it copy control information is included in the program detailed picture.In the example of Figure 15, as the icon display copy control information, but display packing both can be a text line, also can be the image beyond the icon.
And, but allow not have under the situation of record reproducing device 100 of recording medium 115 of installing/dismounting of the management area that the user can not visit (promptly carrying out under the situation of the record reproducing device 100 of the video recording of the non-corresponding medium of copyright administration), as shown in figure 19, copy control information under the copy control information under the situation of demonstration " to the video recording of the corresponding medium of copyright administration " and the situation of " to the video recording of the non-corresponding medium of copyright administration ".In the example of Figure 19, with icon display, show under the situation of " to the video recording of the corresponding medium of copyright administration " to be copied to eight, show not reproducible under the situation of " to the video recording of the non-corresponding medium of copyright administration ".
Next, content is utilized the digital_recording_control_mode information of descriptor, and perhaps an example of processing that is not included in the generation electric program guide of the situation in the SI information about the information of duplicating control of answering a pair of with it describes.The unique situation about determining of control mode of duplicating that each broadcast office uses, for example, certain program of playing that partial seeding puts all be " allow one from generation to generation duplicate ", under the situation of " can duplicate a plurality of ", the program detail information screen displayed should the employing of broadcast office copy control information.
At this moment, allow (compatibility) but do not have under the situation of record reproducing device 100 of recording medium 115 of installing/dismounting of the management area that the user can not visit (promptly carrying out under the situation of the record reproducing device 100 of the video recording of the non-corresponding medium of copyright administration), copy control information under the copy control information under the situation of demonstration " to the video recording of the corresponding medium of copyright administration " and the situation of " to the video recording of the non-corresponding medium of copyright administration ".
In addition, the control mode of duplicating that each broadcast office uses does not have under unique situation about determining, duplicate in broadcast office one side control program programm name import copy control information ahead or at last, the programm name that will comprise this copy control information when generating the program detail information picture is inserted program detail information picture and demonstration, can point out the copy control information of this program thus to the user.And, but allow not have under the situation of record reproducing device 100 of recording medium 115 of installing/dismounting of the management area that the user can not visit (promptly carrying out under the situation of the record reproducing device 100 of the video recording of the non-corresponding medium of copyright administration), identification program names ahead or the copy control information that appends at last, copy control information under the copy control information under the situation of demonstration " to the video recording of the corresponding medium of copyright administration " and the situation of " to the video recording of the non-corresponding medium of copyright administration ".
Figure 16 person of being to use uses a teleswitch or an example of the program search picture of operating portion 110 when retrieving program from play predetermined program.The 1601st, the various settings hurdle of the various settings in the setting program search.In the present embodiment, make it possible in various settings hurdle, the copy control information setting item is set, can carry out the setting of input copy control information in searching object.In the copy control information of Figure 16 was set, " nothing is duplicated control " tested can " to allow (one from generation to generation) a plurality of duplicating " to " can duplicate " by check button (チ エ Star Network ボ Application), and the user retrieves according to the project after checking.For example insert under the situation about retrieving " allowing (one from generation to generation) a plurality of duplicating ", the result after the retrieval only shows the program of " allowing (one from generation to generation) a plurality of duplicating ".Certainly also can utilize the retrieval of key word or the retrieval of use pattern simultaneously.And copy control information is set can carry out a plurality of settings simultaneously, also can cancel one-hundred-percent inspection in addition.
When retrieving, about additional this project that check is arranged, utilize the digital_recording_control_mode information of descriptor with reference to the content that in SI information, comprises, perhaps about carrying out whether consistent checking with its a pair of information of duplicating control of answering.When in SI information not content utilize the digital_recording_control_mode information of descriptor, perhaps under the situation about the information of duplicating control of answering a pair of with it, what each broadcast office used duplicates under the definite uniquely situation of control mode, and the broadcast program of this broadcast office is all retrieved as the program of this copy control information.When in SI information not content utilize the digital_recording_control_mode information of descriptor, perhaps under the situation about the information of duplicating control of answering a pair of with it, each broadcast office uses duplicates control mode when determining uniquely, broadcast office side by in programm name etc. with text line input copy control information, judge whether to comprise this text line and retrieve.
Figure 17 is an example of expression retrieval program search display frame as a result during program from play predetermined program.To show with the form of complete list about the result of the copy control information in the copy control information setting item of Figure 16, set retrieval.The 1701st, result for retrieval guide look display field, the copy control information that comprises for this program shows.And display packing also can be to show by text line, also can show with the image of icon etc.In addition, copy control information also can only be to duplicate information from generation to generation, also can only be reproducible number information, but the reproducible number information of preferred demonstration.
And; when in SI information, there not being content to utilize the digital_recording_control_mode information of descriptor; perhaps under the situation about the information of duplicating control of answering a pair of with it; what each broadcast office used duplicates under the definite uniquely situation of control mode; the control mode of duplicating of this each broadcast office is managed as table; this table of storage is protected literary property thus in the anti-tamper zone that the user can not visit.
In addition, as the display packing of reproducible number information, considered the situation that program videoed in the copy control information of the foregoing description.But recording medium 105 or be inserted in the recording medium 115 of the installing/dismounting in the line of rabbet joint 114 there to be and the program of playing predetermined programme content equivalence video recording.Here, the program of so-called content equivalence is meant, for example by other the program of playing in the same time on date of apparatus video recording, and program that perhaps is played and the program that is played once more etc.Whether be program of equal value, for example be with type, program code, channel, the time on broadcast date of program, play area etc. and judge as the identifying information of program.Whether the analysis result of the content of length of program (time) or program (video-audio data) etc. also can add to is in the judgement key element of equivalent program.The program of displaying contents equivalence like this, the content of program repeats also to show.This detects, and whether when being judgement of equal value, it is on all four not needing these information, as long as at least a portion (for example title) is consistent can be judged as equivalence (or non-equivalence).
Playing the predetermined program and the program of content equivalence videoed, playing content that predetermined program and video recording finish is additional on the program of equal value copy control information to be arranged, any one all adds under the situation that can duplicate number information, is that the total number of the reproducible number of program of equal value shows as the reproducible number of the broadcast scheduled program of program guide etc. with playing the reproducible number of predetermined program and content that video recording is finished.For example, the reproducible number of the program finished of video recording is 6, and the reproducible number of playing predetermined program is under 8 the situation, and then the reproducible number of the broadcast scheduled program of program guide etc. shows as 14.In addition, in playing predetermined program, do not have under the situation of additional copy control information, even the content finished of video recording is additional in the program of equal value copy control information to be arranged, additional copy information does not show yet in the program that broadcast is scheduled to, when recording schedule, show that " duplicating confined program is recorded.Replace? " the message of such content, the user can select.Thus, the user can know in the lump that the content that video recording is finished is the information of the program of equivalence, can improve user's ease of use.
