Content utilizes the purposes of descriptor to be, for this program, under the situation of recording and narrating the control information of perhaps exporting about savings (record), is configured (sending).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, the number of times or the generation of duplicating do not limited.And in fact become impossible to redispatching of the Internet.Be also referred to as " it is free to attach duplicating of output protection " 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.In " descriptor_length ", record and narrate the descriptor length that content is utilized descriptor.In " digital_ recording_control_mode ", be " allow a generation duplicate " in the digital copy control information, and, be not to allow the number restriction to duplicate " the situation of object record and narrate " 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 " copy "." 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, as the processing of receiver side, literary composition also has narration with reference to Fig. 7 in the back.
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 PSI (as an example PMT etc.) or the SI of MPEGTS and the information that is sent out.
Digital copy control descriptor representes, information is from generation to generation duplicated in the field control of 2 bits through " 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, represent copy under the situation for " 11 ".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 of in Fig. 3～Fig. 6, explain 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 through " 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 situation 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, through using locomotive function etc., also can duplicate under the situation of the number that duplicates that can confirm to generate.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 situation, makes the acceptance division of each broadcast bear above-mentioned restriction.Be equipped with under the situation with the not corresponding recording mode of digital_recording_control_mode at receiving trap; 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 ".

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 by the data of output protection with do not have encrypted in the numerical data that generational management information is " can duplicate " also not by the data of output protection.
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 through 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 through the operation of stipulating can access internal the data recording area of data.In 301, write down key data.In 302, write down the information regeneration that is 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. and use data.But in the recording medium 115 of such a installing/dismounting, also can copy control information 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 in anti-tamper zone, taking in through confirming under the situation of authentication 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 through 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 of sending to carry out recording schedule from broadcast office, 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 about describing with one of which is contained in the electric program guide of the situation in the SI information for example to a corresponding packets of information of duplicating control a example of processing.
Broadcast office be in the video-audio data multiple be provided with content utilize descriptor or content utilize the digital_recording_control_mode information of descriptor, or about with the SI information of one of which to a corresponding information of duplicating control, transmission numerical data.This numerical data in input terminal 101 inputs is separated into video-audio data and SI information etc. through acceptance division 102.Based on the SI information (for example EIT) of separating through 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 is included in the electric program guide about duplicating generational management information and reproducible number information (below, be generically and collectively referred to as copy control information) with one of which to a corresponding information of duplicating control.
Receiver 3 (record reproducing device 10) is judged the content of the copy control information of demonstration according to that kind of explaining in above-mentioned < copy control information>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 the for example service describing table (ServiceDescription Table) of digital broadcast or the Event Information Table (Event Information Table) representes 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 the situation of free_CA_mode " 1 " of playing for the expression charge, and the generational management information of duplicating when judging record is " copy ".If this method, owing to be the information of in advance sending, 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. through 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 through text line, also can be through the image demonstration (also is later on same about Figure 15) 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.
