The MKB 102 is a cryptographic information block that enables the acquisition of the media cipher [Km] necessary for decrypting the content. It is only used for the occlusion based on the information processing device stored on the user having a valid license. [Kd] treatment (solution 112673.doc -21 - 1337344). This system-application and then follows the so-called hierarchical tree structure of the poor distribution method. It only enables the media to be obtained and benefited when the user device (information processing device) has a valid permission. The user device that is abolished can not obtain the administrative center that is used as a license entity to generate a structure that is intended to break the structure of the device in the user device, that is, it cannot be changed by A device secret record for decrypting the secret record information stored in (10) to obtain a media secret record necessary for decrypting the content. Thus, unauthorized devices can be revoked at any timing, thereby providing encrypted content that can decrypt only devices with valid permissions. The content decryption process will be described later. "» (3) Title Key File As described above, each set of content or multiple content is subject to individual encryption of each application (title wall (CPS unit) Encryption)) is used to manage the use of content' and is stored in the information recording medium. It is necessary to divide the AV (audiovisual) stream, the I music material, the movie, the still image, and the similar image data, the game program, and the network content of the content into the content by the different titles generated for each segment unit. The managed unit, by which the decryption process is performed. For example, the information used to generate such title secrets is the title secret data, and a title secret is selected by decrypting the (encrypted) (four) material generated by a medium or the like. . The use of the title secret record data follows a predetermined encrypted secret record generation sequence: the title key corresponding to each unit is made and the decryption of the content is performed. (4) Rules of Use 112673.doc • 22. Usage rules include, for example, Copy/Reproduction Control Information (CCI). This is copy restriction information and reproduction restriction information for use control corresponding to the encrypted content 101 stored in the information recording medium 100. There are various settings of copy/reproduction control information (CCI), such as the case of setting information of individual CPS units of the content management unit, setting corresponding to a plurality of CPS units, and the like. (5) Repair table As described above, the encrypted content 1〇1 stored in the information recording medium 1 is already encrypted by the predetermined, and one part of the 'content configuration data is configured by the damaged data different from the correct data. . In order to reproduce the content, data overwriting is necessary, in which the damaged data is replaced by the conversion data of the correct content data. The table in which the conversion data is registered is the repair table 105. A large amount of broken data is set to be distributed throughout the content, and when the content is reproduced, it is necessary to replace (overwrite) a plurality of pieces of the damaged data with the conversion data registered in the repair table. Applying this conversion material means that even in the case of performing unauthorized content decryption due to, for example, an encryption secret leak, it is impossible to reproduce the correct content by decrypting the individual content due to the existence of the substitute material. In order to prevent unauthorized access to the use. In addition to the normal conversion data, the repair table 105 includes an enablement analysis for identifying the conversion data of the data identification information configuration bit of the inner valley reproducing device or the inner valley restore application. Xiao Dingyan, for example, this includes a player ID, which is the identification of the player (the device used to execute the host application), or "conversion data including the identification tag" There is identification information generated based on the playback. Including the conversion of the identification mark H2673.doc -23- The data is the data in which the bit value of the correct content data has been slightly changed at the level that does not affect the weight of the content. The processing of the conversion resource 2 will be used later. The details are described. Although FIG. 1 illustrates an example in which the repair table 1〇5 is set as an independent data file, a configuration can be made in which the repair table is not a separate file but a configuration package dispersed throughout the encrypted content 101. The configuration and processing of this will be described later. (6) Data conversion processing program The data conversion processing program 106 is a program including processing instructions for performing data conversion processing by repairing the registered data in Tables 1 and 5, and is used by the host which reproduces the content. This is performed at the data conversion processing unit 154 of the host 1 shown in FIG. Note that the above-described repair table 105 can be set as the data included in the material conversion processing program 106. A virtual machine (VM) for performing data conversion processing is set at the host, and the data conversion processing program 106 executing the information recording medium 1 at the virtual machine (VM) reads out, and the registration item in the repair table 105 is applied. And the data conversion processing of the partial configuration data is performed on the decrypted content. The details of this processing will be described later. Then, the configuration of the host 14 and the driver 120, and an overview of the processing will be described with reference to FIG. The reproduction processing of the content stored in the information recording medium 1 is performed after the data is transferred to the host computer 14 via the drive 12. The host 140 has a reproduction (player) application 150 and a secure VM iso set. The reproduction (player) application ι5 is a content reproduction processing unit U2673.doc • 24· 1337344 兀, and performs processing such as verification processing in content reproduction processing, content decryption, decoding processing, and the like. Executed by the drive. The security VM 160 functions as a parameter generating unit for providing parameters to be applied to the data conversion processing performed in the content reproduction processing, the content reproduction processing being reproduced by the content reproduction processing unit (player The application is executed, for example, the secure VM 16 is set as a virtual machine within the host 14 . A virtual machine (VM) is a virtual computer that directly interprets and executes an intermediate language and does not rely on the "platform to read, interpret, and execute instruction code information from the information recording medium 100 in an intermediate language. The transfer of information or processing requests between the reproduction (player) application 15 and the secure vm 160 by the self-reproducing (player) application 15 to the safety 160 interrupt (INTRP) sequence and self-security* The VM 16〇 to reproduce (player) application 150 performs a response (call) process. The sequence from the application 15〇 to the secure VM 160 interrupt (INTRP), and the response from the secure VM 16〇 to the reproduction (player) application 150 (call) processing execution parameter calculation φ request and application to data conversion processing Provision of parameters (executed in content reproduction processing). These processing sequences will be described in detail later. The main processing performed by the host 140 will be described. After the use of the content, mutual authentication processing is performed between the driver 120 and the host 140, and after the confirmation of the validity of both parties by the verification is established, the encrypted content is transferred from the drive to the host, and executed on the host side. The content decryption process, and further, the above-described data conversion processing by the repair table is performed, thereby performing content reproduction. For mutual authentication performed between the host 丨40 and the driver 12〇, whether each of the devices or applications is registered as a list of abolished (invalid) issued by the Executive Order by II 2 673.doc -25-1337344 The process for determining validity is performed without an authorized device or application. The drive 120 has a memory 122 for storing a host CRL (Certificate Revocation List), and the host crl stores the abolished (invalid) information of the host certificate (public key certificate). On the other hand, the host 140 has a memory 152 for storing a drive CRL (Certificate Revocation List) which stores the abolished (invalid) information of the drive certificate (public key certificate). The memory is a non-volatile memory (RAM), and in the case where, for example, the crl read from the information recording medium 1 is a newer version, the individual data processing units 121 and 15 perform update processing. The new version of the host CRL or drive CRL is stored in the memories 122 and 152. CRLs such as host CRLs or drive CRLs are continuously updated by the administrative center. That is, in the case where an unauthorized device is newly discovered, an update CRL is issued in which a certificate (1) issued to an unauthorized device or a device mountain or the like is added as a new item. Each CRL has a version number and has a set of states in which new latitudes can be compared. For example, in the case where the CRL read from the information recording medium mounted to the drive is newer than the CRL stored in the memory in the drive, the drive performs the CRL update process. The host 140 also performs driver CRL updates in the same manner. In addition to this CRL update processing, the data processing unit m of the drive 12 performs verification processing with a host executed when the content is used, and further performs processing for reading data from the information recording medium and transferring the data to the host. . 112673.doc • 26 · 1337344 The replay (player) application of the host MO is used to reproduce (or record) an application on a data processing device such as a pc and uses, for example, a PC or the like. The hardware of the information processing device performs processing according to a predetermined data processing sequence. The host UO has a data processing unit 15 for performing mutual transfer control with the drive device, etc., for executing: within the cipher: The decryption processing unit 153 of the decryption processing, the data conversion processing unit 154 for performing the material conversion processing based on the previous document in the repaired table, and the decoding processing unit 155 for performing the decoding (for example, MpEG decoding) processing. The data processing unit 151 performs verification processing between the host and the driver, and refers to the driver stored in the memory a 1S2 within the verification process to confirm that the driver is not the deactivated driver 'the memory & (5) is a non-volatile memory (The NVRAMp host also performs an update process to store a new version of the drive CRL in the memory & 152. 'Decryption processing unit 1 53 uses the store The various types of information stored in the memory b i56 and the data read from the information recording medium 1 are generated to generate a key to be applied to the decryption of the content, and the decryption process of the encrypted content 1 to 1 is performed. The data conversion processing unit 154 The conversion processing data registered in the repair table is applied to perform the alternative processing (overwriting) of the content configuration data by following the data conversion processing program obtained from the information recording medium 1〇〇, which is obtained from the information recording medium 1〇〇 The decoding processing unit 155 performs 4 decoding (for example, ΜΡΕ (3 decoding) processing.

and play item ID as identification information. Figure 2 shows two CPS units per month. These components are part of the content stored in the information recording medium. Each of the CPS unit i 271 and the coffee unit 2 is configured to include - a title used as an index, - a power to reproduce the program file, an IV object, a play list, and an AV stream file including The Cps unit of the unit of the clip for the actual content data). The inner valley management unit (CPS unit) 1 271 includes a title 1 211 and a title 2 212, reproduction programs 221 and 222, playlists 231 and 232, a clip 241, and a clip 242, and is included in the two clips 241 and 242. The AV stream data files 261 and 262 of the actual data of the content are at least the encrypted object data, and thus the data is encrypted by setting the application title key (Kt丨) as a rule (also referred to as cps single π key). The title key (Ktl) is an encryption key set corresponding to the content management unit (CPS unit) 1 271. The inner valley management unit (CPS unit) 2 271 includes an application 1 213 as an index, a reproduction program 224, a play list 233, and a clip 243, and is an AV stream data of the actual material of the content included in the clip 243. The file 263 is encrypted by applying a title key (Kt2) which is an encryption key set corresponding to the content management unit (CPS unit) 2 272. For example, in order for the user to execute the application file or content reproduction process corresponding to the content management unit 1 112673.doc -29-1337344 271, it is necessary to obtain one as the content management unit (CPS unit}1 271 The title key of the associated encryption key: Ktl 'and subject it to decryption processing. In order for the user to execute the application file or content reproduction process corresponding to the content management unit 2 272, it is necessary to obtain a setting as the content to be The management unit (cps unit) 2 272 is associated with the encrypted title key: Kt2 and is subjected to decryption processing. Figure 3 shows an example of a CPS unit setting configuration and a corresponding title key. Figure 3 shows a CPS unit setting unit (which A unit for managing the use of encrypted content stored in the information recording medium) and a correlation between each (^8 unit title key (CPS unit key). Note that it can be stored in advance and The CPS unit and the title key for the data appearing later are set. For example, the data unit 281 is used for the item of the data that appears later. The CPS unit setting unit A generic category appears, such as a content title, an application, a data set, etc., and each CPS unit management table has been set therein as a cps unit ID corresponding to the identifier of each of the CPS units. In the case where the title 丨 is, for example, (:1>8 unit five, and when the encrypted content belonging to the cps unit 1 is decrypted, it is necessary to generate the title key Ktl and perform decryption processing based on the generated title key Ktl. In this manner, the content stored in the information recording medium 100 is stored in a manner that has been subjected to encryption processing in each of the suitable units and the encrypted material to achieve different for each of the units. Use control. For each-content management unit (CPS unit), set the UR (Usage Rule) for each __ in the content management unit (CPS unit) for the individual use management setting 112673.doc -30- 1337344. The usage rule is information including, for example, copy/reproduction control information (CCI) of the content, and is copy restriction information or reproduction limit of the encrypted content included in each of the content management unit (CPS unit) Information processing The data processing of various types of information stored in the information recording medium is necessary for the generation of the title secret recording system. The special case of the processing will be described in detail later. Overview of Data Configuration and Data Conversion Processing Next, an overview of the data configuration and data conversion processing including the contents of the revised data will be described. As described above, the encryption included in the information recording medium 100 will be described. The content 1〇1 is set as the damaged data, in which the part of the configuration data is replaced with the data different from the correct content data, so that the separate decoding process does not perform the reproduction of the content in the reproduction, and is used to register in the repair table. The conversion of data to replace the processing of damaged data is necessary. An overview of the configuration of the content stored in the information recording medium and an overview of the reproduction processing will be described with reference to FIG. For example, an Av (such as a movie) inner valley is stored in the information recording medium. Such content is subject to Kaxiong, and content reproduction may be followed by decryption by the application of an encryption key. The encryption key can be obtained only by reproduction with a certain license and by the device. The special content reproduction process will be described later. The content stored in the information recording medium 100 is not only encrypted, but also has a configuration in which the content configuration data has been replaced with the correction data. FIG. 4 illustrates an example of the configuration of the recorded content 291 stored in the information recording medium 100. The recorded content 291 is configured by the uncorrected normal content data 292 and the broken H2673.doc -31 - loss data 293 (which is destroyed by the correction). Damaged data 293 is information that has been broken by the original internal wheat that has been processed by the data. Therefore, since this includes the content 291' of the damaged material, the correct content reproduction cannot be performed. The processing for reproducing the content 296 for replacing the damaged material 293 included in the recorded content 291 with the correct content material in order to perform content reproduction is necessary. The data for conversion (conversion data), which is the normal content data corresponding to each of the damaged data areas, is obtained by obtaining a repair table (FUT) l〇5 registered in the information recording medium 100 ( Referring to the conversion data 295 [Repair 295] in FIG. 1), #, the processing for replacing the private data of the damaged data area is performed, thereby generating and reproducing the reproduction content 296. Details of the special case of the repair table and the reproduction process using a repair table will be described later. Now, when the reproduction content 296 is generated, in addition to the processing for replacing the damage data 293 with the conversion material 297 which is the normal content material, the conversion data 298 (for example, 'one player id') is executed. The processing of replacing a partial region of the recorded content 291 is such that the content reproduction device or the content reproduction application identifiable, the identifier-setting conversion material 298 includes data for analyzing the configuration bits of the identification information. For example, in the event that an unauthorized copy of the content is compromised, analyzing the identifier _ setting conversion data 298 within the leaked content can be used to determine the source of the leak of unauthorized content. Note that the repair record of the stored conversion data is recorded in the information recording medium and set as the file separated from the content. In addition, part of the data in the repair table including the conversion data is recorded in a manner that is determined by the identification of the contents of the content. That is, the conversion data is stored in the repair table 105 shown in the figure, and is also dispersed and recorded in the encrypted content ι〇ι to be recorded as two injuries. An information processing apparatus for performing content reproduction obtains the conversion material stored in the repair table 105 to perform data replacement, or obtains a conversion item recorded in the content in a distributed manner to perform data replacement. In the case of the configuration of the record in a repair table block, which is a repair table configuration data including the conversion data of the determined packet scattered throughout the content configuration data, the 'repair table block configuration data is stored in the The transport stream packet of content has a setting such as shown by circle 5, for example. In Figure 5, (the illusion describes the configuration of the internal-beat material. This content configuration describes the content material consisting of the decrypted transport stream (TS) packet. The transport stream consists of a TS with a predetermined number of bytes (transport flow) The packet configuration. The configuration data of the repair table block including the conversion data is recorded in the form of a divided substance in a part of the plurality of packets of the TS packets. For example, in the TS packet shown in the figure An example of a TS packet for storing a repair table block includes a PMT (Program Map Table) set in the form of a dispersed substance throughout the content, etc. Recorded in the repair table block is used for Performing conversion data (or identifier. setting conversion material) on the alternative processing of the decrypted content, and recording the recording position of the data. For recording the position information, in the case where there are a plurality of recording positions such as shown in (8) of FIG. 5, For example, the offset of the TS packet 3G7 from the inclusion of the repair item (which is the configuration data of the repair table block) is recorded for the first-corrected packet position 'and is indicated from the first-correction packet to the subsequent correction The offset position of the packet 309 relative to the packet location is recorded for the modified packet location of the second packet 112673.doc -33· 1337344. The conversion data recorded in each of the repair table blocks has settings included in the The recording location near the TS packet of the repair item, which is used as the configuration data for each of the repair table blocks 'for example, as shown in (b) of Fig. 5. In (b) of Fig. 5 In the illustrated example, for example, the packets 308 and 309 having the converted data recording area are set near the packet 3〇7 with the repair item. The repair item is the configuration data of the repair table block. The setting is decrypted in real time. In the case of reproducing the content, the data can be replaced by the data of the conversion data as the continuous processing following the decryption, and the detection and analysis processing of the TS packet of the record repair table is allowed to obtain the converted data and is recorded in the table. The process of writing the conversion data (overwrite) is efficiently performed. A configuration of the data conversion processing program 300, the repair table (FUT) 301, and the encrypted content 306 stored in the information recording medium 1 will be described with reference to FIG. As shown in Fig. 6, the repair table 301 recorded in the information recording medium 1 () has a configuration including a secret parameter ID determination table 302 and a repair table main body 3 〇 3a. The repair table main body 303a Set to the repair table group 3〇3b of each clip, the repair table in the unit of each clip is configured by a plurality of repair table blocks 1 to K 304, and further, each of the repair table blocks has one The configuration includes a plurality of repair items 305. Each of the repair items includes conversion data to be applied as substitute data, and record position information of the converted data. FIG. 7 illustrates one of the repair table blocks included. One of the data configuration examples for the fix item (FixUpEntry). As shown in Figure 7, a FixUpEntry contains the following information. 112673.doc •34· 1337344 type_indicator : type identifier [〇〇·· no conversion, 〇lb: processing with conversion data, 10b, 11b: processing with conversion data including identification mark] FM JD—bit—position: The identification bit position corresponding to the identifier-setting player ID is relative to an SPN: the location of the packet, where the conversion data is to be applied (the number from the packet of the PMT packet) byte_position: the position of the conversion data recorded in the packet isvenvrhe —va丨ue : Convert data (also includes identifier_set conversion data) reUtive-SPN-2: location of the packet 'where the second conversion data is applied (number from the packet of the PMT packet) byte-poshion-2: conversion The location of the data recorded in the packet (corresponding to the second conversion data) overwrite a value-2: The second conversion data (including the identifier setting conversion data) is configured from this data. A repair table is set as a repair table for recording conversion data (for replacing one of the content materials) and setting the location information of the conversion data about the content'. This repair table is applied to execute a data conversion including a content configuration data replacement processing execution instruction. Processing the program to perform data conversion. The information [type_indicat〇r] included in the repair item (FixUpEntry) information included in the repair table block shown in FIG. 7 is used to identify the type of registration information of the repair table as follows (a) or (b) The identifier is: 112673.doc • 35· 1337344 (a) Whether it is registration information about the conversion data used to convert the damaged data into the correct content, or (b) about the device or content used for reproduction Reproduce the identifier of the application's identification information - set the registration information for the conversion data.

The registration information [FM_ID~bit-position] is a location information of a reproducing device composed of a plurality of bits or a reference bit of the identification information of the reproducing application to determine the manner of processing. Determining how the data conversion is handled such that, for example, in the case of a reproduction device consisting of a plurality of bits or a bit value of a bit referenced by the identification information of the reproduction application, the bit value of the bit is 丨Registered identifier - Sets the substitution of the conversion data execution content configuration data, and does not perform the substitution if the bit value of the referenced bit is 〇.

And if the conversion data indicates that this is 1, the conversion data is set as a separate conversion data, and the conversion data is selected according to the bit value of the reference bit and set to be appropriate. As shown in FIG. 6, the encrypted content 306 is set as a TS packet stream, and the setting 112673.doc • 36 · 1337344 has a packet stored as a repair item scattered over one part thereof, that is, the repair item storage packet 307a to 307d . The AV stream is divided into units of clips, and the repair items in the frying unit are recorded as scattered throughout the content. As described with reference to Fig. 5, nearby conversion data is recorded in each of the repair items, and the repair items are set as the data of the distributed record. The repair item recorded as the distributed content of the encrypted content 306 is the same as the repair item included in the repair table 3.1, and the information processing apparatus performing the content reproduction performs the self-recording according to the specification of the reproduction (player) application. Obtain conversion data and substitute data for the repair items that are distributed throughout the content, or obtain conversion data from the repair items in Table 1-3 and replace one or the other. As shown in FIG. 6, the content is divided into segments of predetermined units of data. The repair item including each conversion material is subjected to calculation or encryption processing of a parameter (SP: secret parameter) different for each predetermined unit (segment unit) of the content. The information processing apparatus that performs the data conversion processing (which is the data substitution processing performed when the content is reproduced) sequentially obtains the conversion of the secret parameters (SP1, sp2, SP3, ...) to include the position corresponding to the parent-segment. The repair table block of the data performs calculation or encryption processing of the parameter (spn) obtained by the application, thereby performing processing for obtaining the converted data. The secret parameter (SP) ID determination table shown in Fig. 6 is a table for recording guidance information about which secret data parameters should be applied to which content data position. Examples of the details and use of this table will be described later. A special example based on the data of the conversion data will be described with reference to Figs. 8 and 9. First, an example of processing for performing data substitution by obtaining the table configuration data of the repair I12673.doc -37-1337344 including the conversion material will be described with reference to Fig. 8, which has been recorded as distributed throughout. In Fig. 8, (a) illustrates the configuration of the content recorded in the information recording medium 100. The configuration data record including the repair table block of the repair item is distributed throughout the TS packets 307a to 307 &lt;1 shown in the figure. The data replacement processing sequence will be described with reference to (b) in Fig. 8. The processing shown in (1) of Fig. 8 is for executing a host reproduction (player) application. (b) of FIG. 8 illustrates a portion of the Ts packet stream belonging to the content of the segment m=N, N+1 in the content configuration material. For example, the packet 3 n including the repair item recorded in the segment ID=N stores a mutually exclusive or repair item 315, which is a result data of mutual exclusion or calculation by the secret parameter (SPX). The host reproduction (player) application that performs the data substitution processing performs the mutual exclusion or calculation on the mutually exclusive or repaired item 3 15 with the secret parameter (SPX) 3丨6, thereby obtaining the repair item 317, and the self-repair item 317 obtains the conversion data and records the location information to perform the replacement processing of the packets 312a and b at the data replacement location. The parameters (SPx) applied to the calculation to obtain the repair item 317 are supplied from the secure vm 320. For example, the reproduction (player) application obtains the secret parameter ID (sp_iD) used as the secret parameter specification information corresponding to each segment, and rounds up the secret parameter calculation including the notification of the secret parameter 1〇 to the secure VM. The request is requested as an interrupt (INTRp) to obtain the secret parameter (SPn) necessary for each segment of the content. Security ¥^^ responds to the secret parameter (SPx) from the replay (the secret parameter calculation request of the player program is calculated to correspond to dm), and this is used as a response (call D is provided to reproduce (play 112673.doc • 38- 1337344 Releaser) Application As shown in Figure 8, the different segments have different parameters that are applied to the calculation to obtain the parameters of the repair item (SPX). For example, t, each month segment is set to approximately 10 private. The valley reproduces the time, and the replay (player) application receives the parameter recovery restoration items for each segment from the secure VM every 1 sec., the self-recovery repair item obtains the conversion data, and performs data substitution processing. Description processing example 'where the mutually exclusive or repaired item is obtained from one of the repair values of the repair table 303b used as the independent repair table block file, and not from the record of the repaired table block scattered throughout the content, from the processing instance Performing calculation or encryption processing, restoring the repair item, and extracting the conversion data from the restored repair item to perform data substitution. In FIG. 9, (a) illustrates the content recorded in the information recording medium 1〇〇 The configuration of the repair item containing the conversion data is distributed throughout the TS packets 307a to 307d shown in the figure, but for this example, this material is not used, and the value of the edit table 303b is used to edit the value of the clip. For the configuration data of one of the repair records independently recorded in the information recording medium, and the application is stored in the repair value of the clip value stored in the repair table 303 b. The data will be replaced by referring to the description in FIG. 9(b). The sequence is processed in the host reproduction (player) application. The (b) in Figure 9 shows the fragment ID=N, N+11 belonging to the content configuration data. &amp; <part of the content TS packet stream. For example, in the case where the data about the segment ID=N is executed from the 曰n, the slice corresponding to the clip value included in one of the repair values 303b is obtained. =N repair item. However, 'Repair item X 315 is a mutually exclusive or repair item 3 15 as a result of mutual exclusion or calculation with secret 112673.doc -39-1337344 (SPx) The same way the blocks are recorded as scattered The reproduction (player) application of the host for performing data substitution processing obtains the repair item 3 17, by performing a mutual exclusion or calculation on the secret or repair item 315 with the secret parameter (SPx) 316. The repair item 3 17 obtains the conversion data and records the location information, and performs the substitution processing by the data replacement location packets 312a and 312b. The parameters (SPx) to be applied to the calculation to obtain the repair item 31 are the same as the above-mentioned appeal processing example. The method is securely supplied from the VM 320. For example, the reproduction (player) application obtains a secret parameter ID (SP_ID) corresponding to the secret parameter specification information of each segment, and outputs a secret parameter ID to the secure VM. The secret parameter calculation request of the notification is requested as an interrupt (INTRp) to obtain a secret parameter (SPn) necessary for each segment of the content. The secure VM calculates a secret parameter (spx) corresponding to the SP_ID in response to the secret parameter calculation request from the replay (player) application, and calls this as a response (call) to the replay (player) application. Program. As shown in Figure 9, the different segments have different parameters to be applied to the calculation to obtain the parameters (SPx) of the repair term. For example, each segment is set to a content reproduction time of about 10 seconds, and the reproduction (player) application receives different parameters for each segment from the secure VM every ι〇 second, and restores the restoration item 'self-recovery. The repair item obtains the conversion data and performs data substitution processing. Therefore, the replay (player) application for performing content reproduction receives secret parameters from the secure VM and performs calculations in units of each segment, 112673.doc • 40· 1337344 Execution Department G complex table block Recovery of the repair items of the configuration data, and obtaining the restored repair items and performing data substitution. &amp; It is intended that although the above processing example has explained the use of mutual exclusion or (x 〇 R) as the calculation of the application secret parameters, other contention processing can also be applied. Further, a configuration can be made which causes the application secret parameter to perform encryption processing or the like. 4. Reproduction (player) application and secure VM processing In the case of performing the above processing, the reproduction (player) application sequentially obtains different secret parameters (SP1, SP2, SP3... ...) 'Performs content recurrence at the same time, which means that the security VM obtains the secret parameters and performs data substitution before the transition point of the segment is reproduced. In this case, the replay (player) application notifies the secure VM of the secret parameter ID (SP_I) as the secret parameter specification information, thereby determining the necessity. The secret, number ID (SP_I) δ has been recorded in the secret parameter (sp) jD determination table 302 described earlier with reference to FIG. The reproduction (player) application needs to perform processing to set this secret parameter (SP) ID confirmation table 302 to a referenceable state. A series of processing sequences executed by the reproduction application and the secure VM will be described with reference to FIG. As described earlier with reference to Figure 1, the transfer of information or processing requests between the reproduction (player) application 150 and the secure VM 160 is interrupted by the self-reproducing (player) application 150 to the secure VM 160 (mTRP) The sequence, and its response (call) processing from the secure VM 160 to the replay (player) application 15〇. The processing sequence shown in FIG. 1A is a description of the processing performed between the reproduction (player) application 15 and the secure VM 160 (from the point of recording the media information of the inserted content, 112673.doc -41 - 1337344) A diagram of the type of its popup). For example, step S11 is a process for media initialization (age 3 IniHaIiZe) 'which is executed as a process when inserting an information recording medium (Disc), wherein the reproduction (player) application 15 loads a storage for The initial reproduction process is the necessary code information to the content code file (C〇ntent C〇de FUe) in its memory, and execution begins. The Content Code File determines the manufacturer model of the reproduction (player) application, and the like. For example, the security VM 160 determines whether the obtained model is a model in which security issues have occurred in the past, and here is a case where a model of security issues has occurred in the past, by executing the content code (Content Code) A check is made as to whether a similar security issue has occurred. For example, checking the determined value in the RAM of the information processing device or the operation of a determining device checks whether it is in a correct state. Note that the checker for each model may not be included in the originally loaded content code file' and in this case access another necessary content code file. Upon completion of the initialization process by the secure VM 160, a response (call) is notified to the reproduction (player) application 150, and the flow proceeds to the next step § 12. At step S12t, initialization processing (Title Initialize) is performed. The title application is specified information of the content to be reproduced, the title corresponding to the determined content to be reproduced is selected based on the user specification or the like, and a title initialization processing request is reproduced with the title information (player) The application 150 outputs to the secure VM 160.

Note also 'can perform during the title initialization and the media initialization in step S 丨Security Check Same Security Check β An example of a process for generating a repair table on the memory of the secure VM 160 by collecting conversion data corresponding to all clips necessary for reproducing the title will be described with reference to FIG. This instance is executed during title initialization. Figure 11 illustrates a memory area (e.g., 2 MB) that can be used by the secure VM 160. The content code of the code information included in the security conversion program included in the security Vm 16〇 information storage medium is stored here. Note that this content code includes a repair table that is subjected to fuzzification such as encryption. After the self-reproduction (player) application 150 inputs the title initialization request, the secure VM 1 60 performs the decryption of the repair table by collecting the conversion material information corresponding to all the clips necessary for the reproduction of the title from the content code as needed. Processing, storing the state (masked state) subjected to processing such as the above-mentioned mutually exclusive or state in the memory, and notifying the reproduction (player) application 15 of the memory storage location. This notification processing is performed as a response (call) to the title initialization request (INTRP) from the reproduction (player) application 150. After receiving a response (call) to the title initialization request (INTRP) from the secure VM 160, the replay (player) application 150 copies and stores the repair table storage area in the memory area used by the secure VM 160.

For example, the secret parameter ID (Sp's secret parameter ID (SP_ID) determination table of Sp is described as described earlier with reference to FIG. 6 to FIG. 9 is extracted and copied and stored in reproduction (playing) In the memory area that can be used by the application 1 50, as described earlier with reference to FIG. 8, the reproduction (player) application executes the processing for obtaining the conversion data for the self-recording of the repaired table block for the distributed content. In the case of 'getting a secret parameter ID (Sp_ID) determination table is sufficient 'however' in the player as described with reference to FIG. 9, that is, an unused record is played for the repaired table block scattered throughout the content. In the case of the device, the processing for copying and storing the repair parameter table of the secret parameter ID (SP_ID) determination table and the storage repair item is performed in the copy processing in the memory area available to the player. The described mutually exclusive or repaired table block is a repair table block that is copied to the memory area available by reproducing (player) application 150 in this process. Returning to Figure 10, the description will continue. A process sequence between the (player) application 15 and the secure VM 160 is reproduced, and step S13 is a process corresponding to a secret parameter (SP) calculation (Compute-SP), wherein the reproduction (player) application 150 The secure VM 160 outputs an SP calculation request (INTRP), and the secure VM 160 returns the calculation result (SP) to the reproduction (player) application 150 as a response (call). A Sp calculation is output to the secure VM 160. In the case of (INTRP), the reproduction (player) application 15 obtains Sp-m as the SP-specified information from the secret parameter ID (SP-ID) determination table, for example, and gives its notification. In the case where the SP_ID is obtained as the SP specification information and this is notified of the security I12673.doc -44· 1337344 160, the reproduction (player) application 15 needs to precisely select the SP-ID corresponding to the segment of the content. A special example of the sp-hill selection process will be described. The processing in step su is repeatedly performed for each segment. The processing in step S14 is for the self-reproduction (player) application 15 to the secure VM 160 for division. Outside the secret parameter calculation For example, s, in the case where the request processing is used to perform a security check, the secure VM 160 performs processing according to the request, and responds to the reproduction (player) application 150 with a notification regarding the processing result. (Call) Note that the reproducer (player) application 150 and the secure VM 16 are both capable of writing and reading the scratchpad (eg, player status register, scratchpad (PSR) )) is used for this information transfer. The processing in step S15 is to process the media finalize processing in the pop-up information recording medium (7), and the content code (c〇ntem c〇de) processing status is recorded in the non-volatile memory.

Adding and executing the application request mode after the completion of the mode period In addition, accepting the secret parameter (10) received during this period) the calculation request 'and after the completion of the application request mode, the transition to the correct calculation mode is performed, In the case where the parameter calculation process is performed in this way, the female full VM has a configuration for keeping only unprocessed interrupts before a type of interrupt (INTRp). Ignore the second and subsequent interrupt request. 5. Content Reproduction Processing Next, the content reproduction processing performed by the host will be described with reference to FIG. Figure 13 is an illustration of an information recording medium storing encrypted content; a drive 340 in which the information recording medium 33 is set to perform data reading; and a host 345 connected to the drive to enable data communication And the content stored in the information recording medium 33 is obtained by the drive 340 and a reproduction application (which performs its reproduction processing) is executed. 112673.doc -46 1337344 Note that the host 345 shown in Figure 13 is shown divided into: a reproduction (player) application block 350' which performs processing such as content decryption, decoding, data conversion, etc. 'And a secure VM 360 block with a secure VM 3 60' that performs secret parameter (sp) calculation processing and the like. The information § recorded media 330 stores MKB (Media Key Block) 331, title cc file 332, encrypted content 333 'fixed table 335 and data conversion processing program 334. The host 345 holds the device key 351 for MKB processing. The processing sequence will be described. The host 345 shown in Fig. 13 obtains and reproduces the stored contents in the information recording medium 33 via the drive 340. First, before reading the stored content in the information recording medium 330, the host 345 and the drive 340 perform mutual authentication in step S101. This mutual authentication is used to confirm that the host and the drive are each authorized device or application software. Various types of processing can be applied to this mutual authentication processing sequence. Due to the mutual authentication process, the drive 340 shares a session key (Ks) with the host 345 as a common key. In step S101, after the mutual authentication and the shared session key (Ks) are performed between the host and the drive, the replay (player) application 350 of the host 345 obtains the record recorded in the information in step s 102 by the drive. The MKB 331 in the beginning 33〇 performs the processing of applying the MKB 331 of the device key 351 stored in the memory, and obtains the media key (Km) from the MKB. As described above, the MKB (Media Key Block) 331 is an encryption key block generated based on a tree structure key distribution system known as a type of broadcast encryption method, and has only one based on storage based on A key information block obtained by a media key H2673.doc -47· 1337344 (Km), which is processed (decrypted) by a device key (Kd) in a device that is validly licensed, the media key (Km) Is the key necessary to decrypt the content"

Now, the decrypted content stored in the plain text TS buffer button t is the content containing the above-mentioned damaged assets that cannot be reproduced as it is, and there is a need to perform predetermined data conversion (by replacing the overwritten material).棺田骂骂的资 ::: The processing example of the system - which is recorded as scattered within the encryption: = capital, determine the repair item in the package, from which to extract the conversion ’ 仃 仃 仃 仃 替代 的 。 。 。 。 。 。 That is, this is equivalent to the data conversion processing described in the earlier description of Fig. 8. ;&quot; Divided and recorded in the inbound by + &amp; $only and in the repair of the item is used to perform the conversion data (or identifier - for the alternative processing of the solution 112673.doc · «· 1337344 Setting the conversion data) and converting the recorded data of the recorded position. The security VM 361 is based on the input from the event processing routine 354 and the input of the player information 355 during the content reproduction or before the output processing and during the processing. The recording medium 330 reads out the material conversion processing program 335' including the instruction code information and intermittently generates and outputs secret parameters (SP1, SP2) necessary for changing the repair table recorded in the information recording medium 330 together with the content to the plain text repair table. , SP3.... This processing is performed intermittently. As described above, the 'secret parameters (SP1, SP2, SP3, ...) are the calculation results of the encryption processing parameters for the segment conversion corresponding to the pre-element data unit' and especially For (for example) mutual exclusion or (X〇r) operation parameters. Secure VM 36 1 is executed for intermittent generation and output for recovery repair items (such as by adding The processing of the secret processing is processing of the necessary parameters (sp i, SP2 &gt; SP3, ...) based on the configuration data of the repair table block corrected from the request of the reproduction (player) application. In the reproduction (player) application 35, decryption of the encrypted content 333 including the repair item is performed, and in step S105, the repair item is separated by the processing of the demultiplexer (which is recorded in the content) Repairing the configuration data of the table), and performing the table recovery and data conversion processing under the control of the instant event processing routine 356 in step S106. The control (reproduced) application is reproduced due to the control of the instant event processing routine 3S6. The program 35 forwards a secret parameter calculation request corresponding to the conversion of the segment to the secure VM 36ι as an interrupt (INTRP), and receives security parameters (spi, sp2, 112673.doc • 49-SP3...) from the secure VM 361. Performing decryption or calculation of the repaired table block to obtain a plain text repair table block, and obtaining the repair item included in the obtained repair table block. The repair item records the conversion data, that is, (a) conversion data (b) knowledge - the setting conversion information and the recording position of the information in the content of the above conversion data, and the reproduction (player) application 35 performs the data conversion processing for writing the prescribed position as the content with the content in step 51〇6 The processing or external output processing is parallel processing in real time. For example, the parameters (SP1, SP2, SP3, ...) are mutually exclusive or (measured) operations with corresponding conversion data in the unit of the predetermined content portion data. In the case of the parameters, the recovery processing in step S303 is as follows: [Repair Table Block 1] (XOR) [SP1] [Repair Table Block 2] (X〇R) [SP2] [Repair Table Block 3] (XOR ) [SP3] and so on. The mutual exclusion or arithmetic processing is performed' to thereby obtain the repair items included in the repair table block data order. Note that in the above expression, (4) (x〇r) is a mutually exclusive OR operation of A and B. Therefore, the repair table containing the content recorded in the information record (4): the block is divided into the repair items corresponding to the conversion data and the information of the conversion data corresponding to each content part, and the secret parameters (SP1, SP2) are used.

The secure VM 361 continuously obtains and outputs these parameters. 112673.doc 1337344 In the table recovery and data conversion processing in step S106, the repair item recovered by the acquisition of the application secret parameter (SP1, SP2, SP3, ...) or the encryption process is obtained. The conversion data, including the damage in the content, is replaced by the conversion data of the correct content configuration data, and in addition, the data overwrite processing is performed (where the identifier-setting conversion material is replaced by one part of the content data). Thereby, the stored data in the plain text TS buffer 353 is changed to the converted material. An overview of this data conversion process will be described with reference to FIG. The encrypted content 333 stored in the information recording medium is temporarily stored in the track buffer 352 at the host side. This is the track buffer storage material 401 shown in Fig. 14 (1). Decryption of the encrypted content of the track buffer storage data 4〇1 is performed by the host side decryption process, and the decrypted result data is stored in the plain text TS buffer 353. This is the decryption result data shown in Fig. 14 (2). The decrypted result data 402 includes the damage information 403 which is not the correct content configuration data. The data conversion processing unit of the host performs processing for replacing the damaged data 4〇3 with the conversion data 404 which is the configuration data of the correct content. This alternative processing is performed as part of the data on rewriting (overwriting) of, for example, writing data in the plain text Ts buffer 353. In addition, as shown in FIG. 14, the data conversion processing performed by the host is not only a process for replacing the damaged data with the conversion data of the normal content data, but also is performed by using the identifier/setting conversion data. The processing of one of the configuration data in the decryption result data 402 is replaced. As described above, an identifier is a configuration bit that enables the identification information so that the 51 112673.doc content reproduction device or content reproduces the data identifiable by the application. A special example is a configuration data of an identification information (player ID) used as an information processing device for executing a player of a host application, or an identification mark generated based on a player ID. As described above, the identifier-setting conversion data is information in which the bit value of the correct content material has changed slightly within the level that does not affect the content reproduction. For example, a large number of identifier-setting conversion data 405' is set in the content and a plurality of sets of identifier-setting conversion data 4〇5 are collected and analyzed to determine the player ID. The identifier-setting conversion data 405 is data in which the configuration bit of the normal content data has changed within a level (where normal reproduction can be made into content) and in which the enabling bit is analyzed by the MPEG bit stream This information is determined by the (identification tag configuration bit). The large amount of conversion data 4〇4 and the identifier-setting conversion data 405 shown in Fig. 14 are registered in the repair table stored in the information recording medium, and in addition, the writing position information is registered. The data stored in the plain text TS buffer 353 is replaced with the converted material 406 shown in Fig. 14 (3) based on the information stored in the repair table. Subsequently, the converted TS (transport stream) is externally output via a network or the like, and is reproduced at the external reproducing apparatus. Or, in step s7, a conversion from a transport stream (TS) to an elementary stream (ES) is performed by processing by a demultiplexer' and further, after the decoding process (step S108), this is via A display speaker is reproduced. 6. Processing for Obtaining 81&gt; Identifier (Sp_ID) Corresponding to Segments As described above, the content recorded in the information recording medium is divided into slices 112673.doc • 52· 1337344 segments 'so performed for each When the segment is the necessary data conversion process, the secret parameter (spn) is obtained from the secure VM for each segment, and the secret parameter recovery obtained by the application is necessary to recover the repair table block including the repair item. In order to obtain a different secret parameter (SPn) for each segment from the secure VM, the 'reproducer (player) application obtains a secret parameter identifier (SP_ID) corresponding to each segment, and notifies the secure VM of the obtained secret parameter identification. Symbol (SP_ID). Next, a description will be given of a plurality of processing examples 1 to 3 regarding techniques for obtaining a correct secret parameter identifier (SP_ID) corresponding to each segment. (6.1) Processing Example 1 for Obtaining the SP Identifier (sp_ID) Corresponding to the Segment The processing example 1 for obtaining the SP identifier (SP_ID) corresponding to the segment will be described. In the present processing example, the SPN (Source Packet Number) of the identification information packet (TS packet) used as the configuration content is registered in advance in the secret parameter ID determination table described with reference to FIG. 6, and is related to the SP identifier (SP_ID). . The reproduction (player) application that executes the content reproduction first obtains the SPN (source packet number) corresponding to the content material to be reproduced from the EP mapping recorded in the clip information. The clip information is the content reproduction section information. . Further, based on the SPN (source packet number) obtained from the EP mapping, the secret parameter ID field table is searched for and the "identifier (SP_ID) corresponding to the obtained SPN (source packet number) is obtained. Reproduction (player) The application notifies the secure VM of the SP identifier (SP_ID) obtained from the secret parameter id determination table and executes a secret parameter calculation request (INTRP). 112673.doc -53- 参看 系 参看 参看 参看 参看 参看 参看 参看 参看 参看Description: Figure 15 is a diagram of the content reproduction process by the content reproduction unit, which reproduces the intra-valley reproduction, that is, a reproduction (player) application. First, In the reproduction of the content, the reproduction (player) application obtains the clip information 'the clip information is the reproduction section information of the content. For example, the clip information illustrated in Fig. 15A is selected. The clip information includes the content. The packet identifier information is set as a mapping of a plurality of sets of data. The parent-EP mapping includes, for example, G〇p (for) a coding data unit used as one of MPEG data (which is an encoded data of a configuration AV stream) Image group) Encapsulation information of an image within one, the AV stream is the reproduction content shown in Fig. 15B. The SPN (source packet number) is included in the packet information of the image included in the Ep mapping. For example, ' As shown in Fig. 15C, each -G〇p (image group) is configured by an image 411 and a plurality of P&amp;B images. The j image 411 is set as the encoded material of one of the reference images, and !&gt; and 3 images are application image information as the image information of the reference information. / The main idea is as shown in the figure, the packet to be set as the damaged data is located in the unit of the TS packet, and the TS packet is set.组态 Image 411 or 1&gt; and 8 of the configuration data of the image, that is, each image, or 5&gt; and B image is stored as being dispersed in a large number of TS packets. For example, 'will constitute this G〇 One of the D 8 packets of the I picture 411 in p is set as the correction data (damaged data) means that the I image of the reference of the MPEG citation data is broken, so the ί image is used as a pair for restoration (MpEG) The P image and the B image of the reference to the information of the decoding cannot be recovered, and therefore, 112673.doc •54- can perform effective data breaking ^Reproduction (player) application for reproducing content obtains conversion data recorded in the repair table by data conversion, and performs data substitution. Note that as described above, data substitution is not only used for damage The data is substituted for the conversion data, and also for the identifier-setting conversion data. As described above, the conversion data is registered in the repair table, but subject to the calculation or encryption of the different secret parameters (sp) applied to each segment, and thus The replay (player) application for reproducing the inner valley must obtain the secret parameters corresponding to each segment from the secure VM. For this processing example, the replay (player) application is self-registered for use as content reproduction. The EP mapping in the clip information of the section information obtains the SPN (source packet number), searches the secret parameter (1) based on the obtained SPN (source packet number), and obtains a table corresponding to the SPN (source packet number) (for recurring execution thereof) ) the sp identifier (SP_ID). First, the details of the EP mapping will be described with reference to Figs. As shown in Fig. 16, the EP map (EP_map) 412 is data included in the clip information slot (clip information). The detection of the I picture position based on the EP mapping will be described with reference to FIG. Figure 17A shows a clip AV stream, each rectangle indicating a source packet of 192 bits. Each source packet is set with a time stamp and the processing time is redefined. Figure 17B illustrates the detailed configuration of source packet (XI). Each source packet is configured by the TP_extra header and transport packet. The transport packet consists of various types of header information and I-PIC used as MPEG2 entity data. Information such as configuration 0 112673.doc • 55· 1337344 The clip information shown in Fig. 17C includes the EP mapping as described above. As shown in the figure, the EP map includes various materials of [PTS-EP start], [SPN-EP start], and [I_end_position_offset]. The meaning of each information is as follows. PTS_EP start : corresponds to the time frame (presenting the current stamp) of the source packet including the sequence header. SPN_EP start : The header address of the source packet including the sequence header. I_end_position_offset: The source packet including the end of the I picture is offset from the source packet including the sequence header. Figure 17D illustrates the relationship between such data.

A position_offset] can be used to obtain the position of the I image in the source packet based on this data. For this processing example, the reproduction (player) application for performing content reproduction self-registers the Ep map in the clip information (which is the content reproduction section information) to obtain the material corresponding to the content to be reproduced. SPN (Source Packet Number), based on the obtained SPN (Source Packet Number), searches for the secret parameter m by the determination table, and obtains the sp identifier (sp_ID) corresponding to the SPN (source packet number) to be reproduced. Figure 18 shows an explanation of the secret parameter ^. (1) Determining a data configuration example of a table and a flowchart of a SP § ten request processing sequence, and reproducing a (player) application executing the SP calculation request processing sequence with respect to the secure VM. Each step of the flowchart shown in Fig. 18 will be described. First, in step S201, the reproduction (player) application for playing the content obtains the potential information of the reproduction section information of the content to be reproduced by 112673.doc -56-1337344, and further, in the step In S201, 'the sand map included in the clip information is obtained. Further, an SPN is obtained from the EP mapping obtained in step S203, and the SpN is a source packet number indicating the reproduction position. For example, it can be said that the source packet number has been obtained: spN=9451〇〇〇. Then, in step S2〇4, the SP_ID determination table is referred to. Note that the sp-m determination table is the configuration data of the repair table stored in the information recording medium as described earlier with reference to FIG. 6, and as described earlier with reference to FIG. 1 and FIG. Now in the memory area that the application can use. As shown in Fig. 18, the SP_ID determination table is recorded as a correlation table between the sp_ID and the source packet number (SPN). The sp-ID determination table shown in the drawing is an SP_ID determination table corresponding to a clip. The source packet number (SPN) registered for each spjD is equivalent to the first packet number in each of the constituent contents. In the example of the SP_ID determination table shown in the drawing, for example, the segment corresponding to the inner valley of SP-ID-124 is the content of the packet number (spn) 9 362153 to 94443 10 ' and SP_ID=125. The fragment is the packet number (SPN) 9444311 to 9528254. It can be said that in step S203, the reproduction application has obtained the source packet number from the Ep mapping in the clip information: SPN=9451000 » In step 82〇4, the reproduction application obtains the source packet from the SP-ID determination table. No. SP_ID of SPN=9451000 For the example of the SP_ID determination table shown in Fig. 18, the source packet number: SPN=9451000 belongs to the packet number corresponding to SP_ID=125 H2673.doc -57· 1337344 (SPN)=944431 1 to 9528254. Therefore, the secret parameter concept corresponding to the source packet number: SPN=9451000 is SP_id=125. In step s2〇5, the secret parameter ID [SP__ID=125] corresponding to the source packet number: spn=9451〇〇〇 is obtained in this way. In step S206, the reproduction (player) application notifies the security server of the obtained secret parameter ID [SP_ID=125], performs a secret parameter (SP) calculation request (INTRP) corresponding to the fragment, and is self-safe. Vm obtains the secret parameter (SP) corresponding to the segment. A configuration example of the repair table and the SP_ID determination table which can be applied together with the present processing example will be described with reference to Figs. Fig. 19 is a view for explaining the configuration of the repair table. The repair form includes the following information.

First, the 'reproducer (player) application determines the title to be reproduced in step S401, and issues a title initialization instruction to the secure VM. In the step-by-step, the secure VM performs the header (four) processing, and the generation processing corresponding to the title repair table (FixUp application) is executed. This is the process previously described with reference to Fig. 10 (10), and corresponds to the processing in step S12 of the sequence diagram shown in __.

In the case of a reproduction (player) application that performs data conversion by extracting a FUT block multiplexed on the TS (transport stream) of the content, thinking is performed earlier with reference to FIG. In the case of the reproduced (player) application of the processing described, only the secret parameter (sp) ID determination table is copied into its own memory area. On the other hand, a reproduction (player) application that uses the conversion data recorded in the repair table block in the repair table file without using the FUT block multiplexed on the content TS (transport stream) In this case, it means that the reproduction (player) application (FUT preload type player) of the processing described earlier with reference to Fig. 9 is executed, and the entire repair table is copied into its own memory area. Then, in step S404, the reproduction (player) application obtains the clip information corresponding to the title, and obtains the source packet number corresponding to the reproduction starting point from the £1&gt; map included in the clip information (8? ]^) value β and then 'in step S405' based on the SPN obtained from the self, the secret parameter ID (SP_ID) of the starting point is determined from the SP_ID determination table (SPChangeP0Siti0nTable()). This processing is as described with reference to FIG. Processing. Then, the secure VM is notified with the obtained secret parameter ID (sp_ID) in step S406, and a secret parameter (SP) value calculation request is output. This processing is equivalent to the processing in step S13 described with reference to Fig. 10. 112673.doc -61 · 1337344 Then, in step S407, the reproduction (player) application obtains the secret parameter (SP) value corresponding to the segment calculated by the secure VM, and executes the repair table block based on the secret parameter (SP) Recovering, obtaining a repair item stored in the restored repair table block, performing data conversion processing of the data in the clip of the content replacement by the conversion data based on the converted data recorded in the repair item and the position of the record, and in the step In S408, decoding and reproduction processing are performed. In addition, in the case of proceeding to the next segment, in step S4, the SPN of the next reproduced segment is obtained from the EP mapping, and the processing starting from step s4〇5 is performed, that is, based on the EP mapping. Obtaining the spn, obtaining the SpJD corresponding to the fragment from the SP_ID determination table (SPChangePositionTableO), and notifying the security VM of the obtained SP-ID, obtaining the threshold value corresponding to the fragment, restoring the repair table block based on the obtained SP value, and recovering itself The repair table block obtains the repair item, extracts the conversion data and the record position from the repair item, and performs data conversion processing for each piece, and the data in the clip part of the content is replaced by the conversion data. According to this processing, the processing of applying different secret parameters (SP) for each segment is performed. Then, reference will be made to the description of the processing sequence in the case of performing special reproduction processing such as random access. Note that the processing shown in Fig. 24 only describes the processing sequence after the header initializing processing. That is, this shows the processing after the completion of the processing steps 84〇1 to 84〇3 in the processing flowchart shown in Fig. 23. First, in step S421, the reproduction (player) application &lt; in response to a special reproduction processing request such as random access, obtains one (four) 112673.doc -62-1337344 from the clip information and obtains from the obtained EP The mapping obtains a source packet number (SPN) value corresponding to the reproduction starting point. Then, in step S422, the secret parameter ID (SP_ID) at the starting point is determined from the SP_ID determination table (spchangePositionTable()) based on the SPN obtained from the EP mapping. This processing is the processing described with reference to FIG. Then, in step S423, the secure VM ' is notified with the obtained secret parameter ID (SP_ID) and the secret parameter (SP) calculation request is output. This processing is equivalent to the processing in step S13 described with reference to Fig. 10. Then, in step S424, the replay (player) application obtains the secret parameter (sp) value corresponding to the segment calculated by the secure VM, and performs recovery of the repair table block based on the secret parameter (SP) 'obtained for storage and recovery The repair item in the repair table block performs data conversion processing of the data in the fragment of the content by the conversion data based on the conversion data recorded in the repair item and the position of the record, and in step S425, performs decoding and heavy Processing now.

Referring to FIG. 15 earlier, 'set an EP mapping for each GOP, and the reproduction (player application) performs the process of obtaining the EP mapping in the clip information and extracting and reproducing the reproduced packet. For this processing example, The current (player) application applies an EP mapping registry ID corresponding to the EP mapping used to calculate the secret parameter ID (SP_ID). Alternatively, the replay (player) application maps the registry to the Ep used. The number is counted and it is determined that a segment conversion will occur each time the number of EP mapping registries that make up a segment (corresponding to the number of Ns of the EP mapping registry) will occur and thus the execution for conversion is to be applied The processing of the secret parameter (SP) of the recovery of the table block.

The setting example shown in Fig. 28 is 'n=5, so it is determined that fragment conversion will occur every five Ep mapping registers' so that the SP_ID is incremented by one every five EP mappings, the SP_ID is determined, and the determined SP-ID is output to Secure VM, and get the secret parameters corresponding to the fragment. It is carried out without specifying that the segment can be determined in an integer unit other than N = 5, but in consideration of the processing time of the reproducing device, it is necessary to determine one of a plurality of EP mapping registry entry points. For this processing example, different SPjDs for each segment can be obtained based on the above expression or Ep mapping registry count, so there is no processing example 1 and 2 as described earlier for using a source packet number or secret parameter 1 112673.doc • 72· 1337344 The table needs to obtain the secret parameter (1) based on the EP mapping registry id. In the case where the present processing example is applied, a flow of the content reproduction processing relating to obtaining a secret parameter (sp) different for each-segment, and data replacement by conversion data will be described with reference to the flowchart shown in FIG. First, in step S601, the reproduction (player) application determines the title to be reproduced, and issues a title initialization instruction to the secure VM. In step S602, the secure VM performs title initialization processing, and performs generation processing corresponding to the title repair table (FixUpTable). This process is described earlier with reference to Figs. 1A and 11 and corresponds to the processing in step S12 of the sequence diagram shown in Fig. 1A. In step S603, the 'reproducer (player) application self-repair table (FixUpTable) obtains the necessary information. This is performed earlier with reference to the processing described in the figure 'and as a process for copying the necessary information from the self-repairing table to the memory area usable by the reproducing (player) application, which is stored in the secure VM. In the memory area. In the case of a reproduction (player) application that performs data conversion by extracting a FUT block multiplexed on the TS (transport stream) of the content, meaning "before performing the reference to FIG. 8 In the case of the reproduction (player) application of the processing described, only the secret parameter (SP) ID determination table is copied into its own memory area. On the other hand, a reproduction (player) application that uses the conversion data recorded in the repair table block in the repair table file without using the FUT block multiplexed on the content TS (transport stream) In this case, it means that the reproduction (player) application (FUT preset type player) of the processing described earlier with reference to FIG. 9 is executed, and the entire repair table is copied to -73-112673.doc 1337344 to its own In the memory area. Then, in step S604, the reproduction (player) application obtains the clip information corresponding to the title, determines the EP map included in the clip information, and obtains the value of the EP mapping registry ID as the registered Ep map. Table identification information. Then 'in step S605, the SP-ID is calculated based on the EP mapping registry ID. For example, the number of Ep mapping registries included in the snippet is N, and the SP_ID is calculated as:

This processing is equivalent to the processing in step S13 described with reference to Fig. 10. Then, in step S607, the reproduction (player) application obtains the secret parameter (sp) value corresponding to the segment calculated by the secure VM, performs recovery of the repair table block based on the secret parameter (SP), and obtains the storage for recovery. The repair item in the repair table block performs data conversion processing of the data in the fragment of the content by the conversion data based on the conversion data recorded in the repair item and the position of the record, and performs decoding in step 86〇8.
