The explanation of the non-reference position

Detailed description of the invention

Certain variants of execution, to which is applied the present invention will be described in detail below with reference to the drawings.

Figure 1 shows the basic concept of the system load content, which is an embodiment of the present invention.

System 1 download content made up of device 10 receiving set in the house of the user using the content, and devices 20 provide intended for downloading content in response to requests from the device 10 admission, which is connected via the network 2.

It should be noted that in accordance with this alternative implementation, the download is a processing device 10 receiving consisting in reception and accumulation of electronic data, such as content provided from the device 20 providing via the network 2. In addition, the content includes AV (AV, audio-video) data composed of video data for playback of the corresponding audio data and the corresponding subtitle data, etc. that are encrypted IP is by the use of key content. To use the content, a license is required, which includes the key content for decryption of encrypted data and which describes the terms of use, etc.

Network 2 is a data transmission system, which is the Internet, and can be used with cable network, for example, on the basis of fiber-optic cable, or wireless network or a broadcast network.

It is assumed that the device 10 receiving embedded, for example, in a television receiver or externally connected to a television receiver. The device 20 providing consists of many servers, etc. provided for in network 2 (details will be described later with reference to figure 3).

In accordance with the system 1 download content, as shown in figure 2, the user device 10 may download the content on your choice of device 20 providing via the network 2 and can reproduce the content stored in the device 10 receiving, at any time, to display content outside of the device 10 can receive and record it on the recording media such as DVD (MCC, digital versatile disk). Following the conclusion of the loaded content outside of the device 10 receiving and recording on the recording media shall be called export.

Thus, in the system 1 download sod is Rania used (playback or export) the content, which was basically loaded, so that preferably, but not necessarily to the speed of data transfer between the device 10 and reception device 20 providing via the network 2 was high speed.

Below, with reference to figure 3, will be described in detail an example configuration of the device 10 and reception device 20 provide, the components of the system 1 download content.

The device 10 receiving is from the browser 11, which accesses the device 20 providing, receives the HTML document (AGTR, hypertext markup language) or BML documents (ARCH, the markup language broadcast) or the like, and displays the corresponding web page; loader 12, which represents an application using the browser 11 and which transmits the content and its metadata from the device 20 provide for accumulation in the memory 13; the drive 13, consisting of a drive on a hard magnetic disk or the like; ECG 14, which functions as a user interface for the user to use already loaded content; AV player 15, destined to play an already loaded content; client 16 DRM (DRM, digital rights management), designed to obtain a license, which includes the key content that is required to decrypt the content received zashifrovana condition of the device 20 providing; and devices 17 external pin is used to output content, the playback of the AV player 15, outside the device 10 admission.

The browser 11 displays the web page so that the user can interactively perform the operation of selecting content, such as purchasing and downloading contracts on the use and content of the service loading content, on the basis of documents AGTR, documents JARS, etc. received from the device 20 of grant.

The loader 12 starts running browser 11 on the basis of documents AGTR, documents JARS etc., and he transfers the contents in an encrypted state and metadata corresponding to it, from the device 20 providing and stores them in the memory 13.

There are two types of metadata, metafile 31 control loading (6) and metafile 41 playback control (Fig.7). Metafile 31 management download contains the information described in it, to convey the content and the license to him, and metafile 41 control playback from the device 20 providing. Metafile 41 playback control contains the information described therein, necessary for the reproduction of the corresponding content.

Next, the loader 12 generates meta-DB (database, the metadata database) 13A, which is information, n is required to view the content list, accumulated in the memory 13, the user, on the basis of the metafile 41 playback control that contains the metadata and stores it in the memory 13.

The memory 13 stores the content transmitted from the device 20 providing and its metadata. In addition, it contains a base 13A metadata generated by the loader 12.

ECG 14 is a resident application, and on the basis 13A metadata contained in the memory 13, presents the user with a list already loaded content, and submit to the local list of user content that is user interactive GUI (GUI, graphical user interface)for selecting content for playback (viewing/listening) or export.

AV player 15, launched ECG 14, reads the content for playback from the drive 13, and only when satisfied the conditions specified RMPIp (information terms of use playback)transmitted from the client 16 MCC, the content encrypted using the key of the content transmitted from the client 16 MCC, decode and then encode decode so that reproduce the AV data corresponding to the video image display on the display and the sound output from the speaker (none of this is x elements not shown).

In addition, the AV player 15 reads the content that is intended for export, from the drive 13, the content is encoded, using the keys of the content transferred from the client 16 MCC, decode, and the coded data obtained by decryption, the output of the device 17 external output.

After establishing a reliable data transmission channel with the server 26 DRM device 20 providing the client 16 MCC receives a license that includes a key content from the server 26 MCC, and itself contains a license. In response to a request from the AV player 15, the key is to provide content in the AV player 15 only when satisfied the conditions of use described in the license.

Only when the conditions expressed RMPI (information terms of use export)transmitted from the client 16 MCC, the device 17 external output converts the encoding method corresponding to the output destination (the recording media such as DVD, playback device, recording device, etc.) the coded data of the AV player 15, accordingly, encrypts them again and displays in the field next output destination.

The device 20 providing compiled from the web server 21, which provides documents AGTR, documents JARS etc. to display interactive web pages in device is iste 10 admission, the server 22 to the client management tool for managing information relating to the client upload services content server 23 accrual account/calculation, performing a calculation with clients in the case of using the service loading content server 24 metadata intended for transfer metadata corresponding to the content, the device 10 receiving, the server 25 content intended for transfer content to the device 10, and the server 26 MCC intended to grant a license to the device 10 admission.

The web server 21 sends a document AGTR, documents JARS, etc. to display the web pages of various types in the browser 11, in response to requests from the browser 11 of the device 10 admission. The server 22 and client management correlates and manages the packages (in units of product)purchased by different customers, and downloaded content to customer information (for example, ID (ID, ID) of the client, the password information for the calculation of accounts (credit cards etc), production ID, device 10 receiving, the client ID 16 PMU (ID MCC), and so on) of the client (user of the device 10 admission).

The server 23 accrual account/calculation handles the accrual account/billing customer, for the customer in response to requests from the server 22 and client management.

The server 24 manages metadata information is the situation, related packages (modules work content) and the content, and provides the requested information in another server, transmitting the metadata, such as a metafile 31 control loading and metafile 41 playback control, the loader 12, in response to requests from the loader 12 of the device 10 admission. The server 25 transmits content the content of the loader 12 in response to requests from the loader 12 of the device 10 admission.

After establishing a reliable data transmission channel with the client 16 DRM device 10 receiving server 26 MCC provides the client 16 FCC license, which includes key content to decrypt the encrypted content.

The license may include the following types. Then there exist a valid license such as a license to reproduce (for example, the playback of the content is 7 nights and 8 days, or the like), license for additional playback (for example, the playback extended for one night), the license for the preview (test viewing/listening) (for example, the playback time of the content is limited to 10 minutes), the license serial download (playback during download of the content; not suitable for use when the download is complete), the export license (for example, the content can skopinova the ü on DVD only once), etc. and bogus license (for example, the validity period is set as an extremely short period, and the content may not actually be used). The license granted to the client 16 MCC and contained therein, is automatically removed when it expires.

It should be noted that the web server 21 via the server 26 MCC, which is the device 20 providing can be executed concentrated in the network 2, or may be dispersed. In addition, a number of devices between the web server 21 and the server 26 MCC can be combined, or the functionality between the web server 21 and the server 26 MCC can be provided on a single server.

Next, with reference to figure 4, will be described the contents transmitted from the device 20 to provide the device 10 receiving and playing in it.

After encoding compression with a given encoding method (for example, using MPEG 2) in the server 25 content device 20 providing, AV data constituting the content, convert transport stream data (TS, TP) along with the data of the subtitles and the like, and transmit the device 10 receiving an encrypted state with the increment in the TS package using the key KS of the content generated by the server 26 MCC, and accumulate in the memory 13.

On the other hand, the key KS of the content that is used to decrypt containing the Oia in an encrypted state, provide from the server 26 DRM device 20 providing, separately from the content, the client 16 DRM device 10 receiving the condition included in the license, along with RMPIp (information about the terms of use playback).

The content encrypted with the increment in the TS package, accumulated in the memory 13, is subjected to encryption, which decrypts the AV player 15 using the key KS of the content provided from the client 16 MCC, and TA MPEG 2, result, decode. However, the provision of key content from the client 16 MCC is limited to cases in which satisfied the conditions of use (the period of use, the number of times of use, etc), described in RMPIp.

Next, with reference to figure 5, will be described the contents transmitted from the device 20 to provide the device 10 receiving and exported.

The content of the encrypt and loaded into the device 10 receiving, as described above. On the other hand, the key KS of the content that is used for decrypting the content in an encrypted state, provide to the client 16 DRM server 26 DRM device 20 providing, separately from the content of the device 10 of the receiving state, when it is included in the license, along with RMPIe (information terms of use when exporting).

The content, which is encrypted with an increment of packages TA nakoplennoj drive 13, subjected to encryption, which decrypts the AV player 15 using the key KS of the content provided from the client 16 DRM and MPEG 2 TS, the resulting served in the device 17 external output. In the device 17 external output only when satisfied the terms of use (number of times of copying, output destination, etc), described in RMPIe, TP, MPEG-2, convert the encoding method corresponding to the destination device output, and again encrypt and then output.

Next, with reference to Fig.6 and Fig.7, describes the metadata that the device 10 receiving receives from the device 20 of grant.

Figure 6 shows a descriptive example of a metafile 31 control loading, which describes the content and the corresponding license, and information intended to download metafile 41 control playback. It should be noted that the metafile 31 upload control does not necessarily correspond to the same content and corresponds to the loading module, composed of one or more parts of the content.

In the metafile 31 control loading, the name of the module to load the content described in <dl_unit_name>. Boot time (immediately reserved date/time, fixed time) of the content included in the download module, described in <dl_timing>.

It should be noted that in the case, to the GDS many parts of the contents included in the module download in the elements after them, from <criid> to <AB_media> describes only the number corresponding to the multiple pieces of content.

It should be noted that in addition to the items described in example display 7, the information section of the content information index management trukovym playback (information display the time and size for each GOP (GRIS, the group of images), information encoding, the information switching audio/subtitles, and so on, can be added to the metafile 41 playback control.

Next will be described with reference to Fig, a brief overview of the processing sequence for the device 10 receiving during download of the content or the like of the device 20 of grant.

Should the tmetal, as preconditions of the processing sequence can be recalled that the user of the device 10 receiving completed registration to use the service at the operator's service loading content, and, thus, customer information relating to the user of the device 10 receiving registered on the server 22 to the client management device 20 of grant, and additional information about the purchased package and downloaded content correlated, and it is managed.

In accordance with operations of the user, the browser 11 of the device 10 receiving accesses the web server 21 of the device 20 providing, and presents the user with a navigation page download, compiled from the list of contents that can be downloaded, etc. After the user performs the operation on the navigation page load, in order to choose the content in the modules load, the browser 11 starts the loader 12.

Running the loader 12 receives the metafile 31 control loading that corresponds to the selected module loading content from a server 24 metadata. It should be noted that the WEAR of the metadata server 24, which represents a source of metafile 31 control loading obtained here, are described in the document AGTR or the like on the navigation page load.

Download the chick 12, after receiving the metafile 31 control loading, transmits the contents of the server 25 content and stores the metafile 31 control loading from server 24 metadata in the memory 13 in accordance with the contents of the metafile 31 control loading. Next, the loader 12 generates a base 13A metadata in order to generate local list of contents on the basis of the transferred metafile 41 control playback, and stores it in the memory 13.

Also the loader 12 prompts the client 16 FCC license. The client 16 MCC requests and receives a license from the server 26 MCC, in accordance with the contents of the metafile 31 control loading received by the loader 12.

This completes a brief description of the sequence of processing to download content, etc.

Next will be described in more detail with reference to a timing diagram figure 9 and the block diagram of the sequence of operations figure 10, the operation of the processing sequence for downloading content, etc. it Should be noted that figure 9 server 24 metadata and the server 25 content integrated with the purpose of their representation in the drawing, and similar approaches can be adopted in other drawings. From the sequence of processing to download content, etc. figure 10 focuses in particular on the processing loader 12 of the device 10 is of Riem.

The prerequisite for the processing similar to the above description, a brief overview. First, at step S11, the browser 11 of the device 10 receiving accesses the web server 21 of the device 20 of grant, and after validation is complete, the user receives documents AGTR, etc. to display the navigation page load, and presents the user with a navigation page load based on the received documents AGTR etc. After the user completes the operation for selecting the content in the modules load, performing interactive operations on the navigation page load, at step S12, the browser 11 starts the loader 12, which represents an application of the aid.

At step S13, running loader 12 accesses the server 24 based metadata SCPI server 24 metadata transferred from the browser 11, receives the metafile 31 load control in accordance with the load modules of the selected content and stores it in the memory 13 (step S31 figure 10).

At step S14, the loader 12 performs initialization processing, to include processing that analyzes the metafile 31 control loading, confirms boot time, confirms the available capacity of the memory 13 after determining the data size of the content will be loaded, and generates a directory in the memory 13 (steps S32-S35 figure 10).

N is the step S15, loader 12 accesses the server 24 based metadata SCPI server 24 metadata, described in the metafile 31 control loading, gets metafile 41 playback control corresponding to each part of the entire content included in the selected modules load, and on the basis of the obtained metafile 41 playback control, at step S16, generate a base 13A metadata and store it in the memory 13 together with the file 41 control the playback (step S36 figure 10).

At step S17, the loader 12 accesses the server 25 content-based SCPI server 25 content and content ID described in the metafile 31 control loading, and requests transmission of the content included in the selected elements of the increment of the load. In response to this request, at step S18, the server 25 content starts sending the requested content, and the loader 12 accumulates the transferred content in the memory 13 (step S37 figure 10).

During this transfer, even if the program was stopped due to interruption of data transmission, at step S19, the loader 12 performs processing for restarting transmission of the content of the state in which the program was stopped after resumption of interrupted data transfer.

After all the download content included in the selected load modules will be completed, at step S20 loader 12. shiveet the client 16 FCC license (steps S3 8 and S39 figure 10). The client 16 MCC accesses the server 26 by the PMU based on the SCPI server 26 FCC ID and license described in the metafile 31 control loading, obtains a license after completing the processing of authentication, which includes notification ID MCC, etc. and notifies the loader 12 that received the license will be kept from him and that the license was obtained. It should be noted that the license obtained here corresponds to the ID license described in the metafile 31 control loading, and there may be cases in which this license is a valid license, and there may be cases in which this license is a fictitious license.

On the other hand, the server 26 MCC notifies the server 22 and client management at step S21 that the license was requested by the client 16 MCC. The server 22 management client invoices/calculates with client server 23 accrual account/calculation, on the grounds that the uploading was completed (however, for example, in the case of mode with a pre-paid fixed amounts, billing/settlement with clients already completed, so that the billing/settlement with clients now fails).

In addition, the server 22 and client management adds information indicating the content that was already loaded in the information CL the clients. Add this information to reflect on the navigation page load, which is specially formed for each client. Accordingly, after that, the client can confirm the content that the client already loaded on the page navigation download. It should be noted that can be assigned to a layout in which the information indicating that the downloading of the content is finished, and it was recognized on the side of the device 20 provide, transmit to the loader 11, and a notification sent to the user device 10 admission.

This concludes the detailed description of the operations of the processing sequence for downloading content, etc.

As described above, the content and the metafile 41 playback control corresponding to each other, remain in the memory 13 of the device 10 receiving the result of this processing, and the license corresponding to the content stored in the memory (but there may be cases of fictitious license)is contained in the client 16 MCC.

Next will be described with reference to 11 a brief overview of the playback processing of the content loaded in the device 10 of the reception.

In accordance with the operations specified by the user, ECG 14 generates a local list of content based on the base 13A metadata contained in the memory 13, and presents it to the user. After vibratorsamateur content and input instructions to perform with a local list of content ECG 14 starts the AV player 15, and the information representing the selected content for playback, passed as notification of the ECG 14 running AV player 15.

In accordance with this notification, the AV player 15 reads and analyzes the metafile 41 control playback of the corresponding content from the drive 13, selects the ID of the license to license to reproduce, relevant content, and confirms whether already license to reproduce, the corresponding ID of the license, the client 16 MCC.

Now, when a licence to reproduce corresponding to the ID license is not contained in the client 16 MCC, that is, in the case where the license contained in the client 16 MCC, is a fictitious license, a license for any other use (for example, a license to play to preview, export license), upon receipt of user approval on the invoice, the client 16 MCC accesses the server 26 by the PMU based on the SCPI server 26 MCC described in the metafile 41 playback control, receives a license to play among the ID of the licenses described in the metafile 41 control playback, and provides key KS of the content included in the AV player 15.

Then, the AV player 15 MF is intended contents of the memory 13, decrypts the encrypted content using the key KS of the content, provided from the client 16 MCC, decodes encoded data obtained as a result of this, to get the AV data, and displays the corresponding video data, and simultaneously outputting audio data.

It should be noted that, even if the license is a valid license can be restricted to the period and the number of reproductions.

In this case, the user shall notify each play that the remaining number of playbacks decreased. In addition, when the license becomes invalid after approval of the user account can be set again, and may be granted a new license.

This brief overview of the playback processing ends.

Further, more detailed processing operation of the reproduction will be described with reference to a timing diagram shown in Fig, and a block diagram of the sequence of operations on Fig. It should be noted that Fig focuses in particular on the processing of the AV player 15, among the playback processing.

In accordance with user-defined operations, at step S81, the ECG 14 reads the base 13A metadata from the drive 13 and, at step S82, generates a local list of content which is submitted is a GUI, on the basis of a few base 13A metadata, and presents it to the user.

After the user completes selection of the content and input instructions for playback of local content, at step S83 ECG 14 starts the AV player 15, indicates information representing the content whose playback has been specified on the instructions for running the AV player 15.

At step S84, the AV player 15 reads the metafile 41 control playback of the corresponding content from the mass storage device 13, and at step S85 analyzes the metafile 41 playback controls and allocates the ID of the license to license the reproduction of the corresponding content (step S91 Fig).

Next, at step S86, the AV player 15 confirms whether already license to reproduce, the corresponding ID of the license, the client 16 PMU (step S92 to Fig). If a license to reproduce, the corresponding ID of the license is contained in the client 16 MCC, that is, in the case where the license is stored in the client 16 MCC, is a fictitious license or the like (YES at step S93 on Fig), AV player 15 notifies the user that to obtain a license, to reproduce the content generated by the account, and presents the user with a confirmation message to confirm the e l e C approved the generated account (step S94 to Fig).

Now, if approved user generated account to obtain a license (YES at step S95 on Fig), the client 16 MCC accesses the server 26 by the PMU based on the SCPI server 26 MCC described in the metafile 41 playback control, receives a license playback, the corresponding ID of the license, is described in the metafile 41 control playback, and after determining that shall be satisfied if the terms of use it provides to the AV player 15 key KS (step S96 to Fig).

AV player 15, received the key KS content, transmits an instruction to read the content in the memory 13 at step S87 and S88, reproduces the content provided from the memory 13 in accordance with this instruction (decrypts the resulting encrypted content, decodes the coded data and receives AV data, while the corresponding video display, and audio output) (step S97 on Fig).

It should be noted that in the confirmation message to the user, when the approval generated accounts for a license is not received from the user (NO at step S95 on Fig), AV player 15 represents the user that the content cannot b is to be reproduced (step S98 on Fig), this local processing of the playback of the content ends.

It should be noted that in the case of playback of the content, the user controls the AV player 15, and can be made of different types of surgery trick play, such as playing with the search-start-up, such as playback, fast forward, playback fast rewind, etc).

After playback of the content, at step S89, the AV player 15 removes the key KS of the content itself, and performs processing completion, which includes the return processing from the user control to the management of ECG 14.

This description of the processing of the playback of the loaded content ends. In accordance with the above-described processing, the playback is confirmed whether there was obtained a license to reproduce the client 16 MCC, in the case of playback of the content, and if it was not received, a license to play again receive from the server 26 MCC. That is, a license to receive, in General, twice on the stage of downloading the content.

Next will be described with reference to Fig, a brief overview of the export processing content that is loaded in the device 10 of the reception.

In accordance with user-defined operations, ECG 14 generates a local is a list of content based on the base 13A metadata contained in the memory 13, and presents it to the user. The user selects the content of the presented local list of contents and instructs on its exports, so that the ECG 14 starts the AV player 15, and the information representing the content selected for export for running the AV player 15, is passed as the notification of the ECG 14.

In accordance with this notification AV player 15 reads and analyzes the metafile 41 control playback of the corresponding content from the drive 13 and confirms whether already export license corresponding to the content, the client 16 MCC.

Now, if the export licence is not contained in the client 16 MCC, after approval, such as billing, will be received from the user client 16 MCC accesses the server 26 MCC and receives an export license based on the SCPI server 26 FCC ID and a license for an export license, is described in the metafile 41 control playback. The key KS of the content included in the license to export, and then provide the AV player 15.

After that, the AV player 15 reads the contents of the memory 13, decrypts the encrypted content using the key KS of the content, provided from the client 16 MCC, and provides the resulting Kadirova the data in the device 17 external output. The device 17 external output, respectively, converts the encoding method, etc. provide coded data, and encrypts them again and displays the destination of the output, which is located after it. This completes a brief description of the export processing.

Next will be described in more detail the operation of export processing with reference to a timing diagram for Fig and block diagram of a sequence of operations on Fig. It should be noted that processing exports to Fig focuses in particular on the processing of the AV player device 15 and 17 external output.

In accordance with user-defined operations, at step S111, the ECG 14 reads the base 13A metadata from the drive 13 and, at step S112 (generates a local list of contents, which is a GUI based read base 13A metadata, and presents it to the user.

After the user completes selection of the content and transmission of instructions to export from a local list of contents, at step S113, the ECG 14 starts the AV player 15, and passes as the notification information representing the contents, the export of which was specified in the instructions for running the AV player 15.

At step S114, the AV player 15 reads the metafile 41 control playback of the corresponding content from the mass storage device 13, and at step S115 is nelisiwe metafile 41 playback controls and allocates the ID of a license for an export license, corresponding content (step S131 on Fig).

Next, at step S116, the AV player 15 confirms whether already export license, the corresponding ID of the license, the client 16 PMU (step S132 to Fig). If the export license corresponding to the ID license is not contained in the client 16 MCC, after receiving approval on the invoice generated in obtaining export licenses (steps S133 and set s134 on Fig), the client 16 MCC accesses the server 26 MCC and receives an export license based on the SCPI server 26 FCC ID and license for export licenses, and determines whether satisfied with the conditions of use included in it, and then provides the key KS of the content in the AV player 15 (step S135 on Fig).

AV player 15 after receiving the key KS content passes into the drive 13 instruction to read the contents, at step S117, and S118 decrypts the encrypted content supplied from the memory 13 in response to this instruction, and provides the coded data obtained as a result of this, the device 17 external output. At step S119, the device 17 external output, respectively, converts the encoding method, etc. provide coded data, encrypts them again and writes the output destination, located after (step S136 on Fig).

Then, after the former is Orta content at step S120 AV player 15 performs the processing end which includes processing the delete key KS content from him.

This concludes the description of the export-processing of the loaded content. In accordance with the above-described processing exports, the client 16 MCC confirms, was already obtained a license to export, in the case of export of the content, and if it was not received, a license is obtained from the server 26 MCC after receiving approval from the user.

Next will be described the operation mode upload services, which can be accomplished by using the system 1, the content of which is applied the present invention. The mode refers to the combination of the time of invoicing for use of the content, use and multiple uses of content.

The time of invoicing may take three points in time: the bill before loading, invoicing after downloading and invoice at the time of service, but for the invoice before downloading and billing after the download, the user can be notified on the screen that is displayed by the browser 11 that will be generated invoice. Billing at the time of service, the user can be notified and give him the confirmation is generated if the setting of the couple and its amount, etc. displaying on the display, the displayed ECG 14.

Modes of use can be coarsely divided into two types: playback (viewing/listening of the content) and export the output to an external device). It should be noted that for playback, it is possible to assume normal playback (for which you set the playback, such as period of play of 7 nights 8 days, but also described as a rental viewing/listening), preview (test viewing/listening) and additional reproduction for use after a period of normal playback (rental viewing/listening) (for example, one additional night), and play during progressive download, which start before the download is finished. Hereinafter, may also be adopted such an export license that one copy can be made on DVD, or the like. Terms of use licenses are different for each of these modes of use, and their difference is described as the license type in the item <license_type> metafile 41 playback control.

The many uses of the same content will be available not only single use mode, once downloaded content, but involves many modes of use the of, in particular, many different modes of use, in accordance with many of the licenses identified above described types of licenses, and the time of invoicing for each mode of use can be set for the already downloaded content. For example, for content, which was previously obtained a license for normal play 7 nights 8 days from the invoice after loading, it is assumed that after the next boot can be additionally purchased a licence for the export so that one copy can be made on a DVD or the like, etc.

For the above modes, which are a combination of the time of invoicing, modes of use and reuse of content, we can assume a variety of types, but considering a feasible operation for each of the seven modes of the structures from a to g, shown below, will be described transitions of screens presented to the user, the sequence of operations and the corresponding metafile 31 control loading, and metafile 41 playback control.

Structure: billing after loading/normal playback

Structure b: billing after the download/export

Structure: the billing at the point of use/playback is the introduction

Structure d: invoicing at the time of use/export

Structure e: billing after downloading/playing + billing at the point of use/additional playback

Structure f: preview + billing at the point of use/export

Structure g: billing before downloading/sequential playback during boot + normal playback

The mode structure and represents a service that provides the period of playback of the content, such as 7 nights 8 days, and provides for the lease of viewing/listening, so that invoicing perform on stage, when the content is already loaded.

On Fig shows the transition of screens presented to the user in accordance with the structure of the mode. The browser 11 displays the first screen navigation download, and the user selects the content And to download on the navigation screen loading, so that, as shown in position a in the drawing, a confirmation screen displays, made up of images of reduced size, appropriate content, a brief description of the content, information, such as "rent view/listen", "7 nights 8 days", "the price of 300 yen", etc. and click "start", and after the op the radio button "purchase and download" on the confirmation screen start the download. Displaying on the screen transitions to a view of the progress of the download, as shown in position on the drawing.

After the download is complete, the contents And, after the user performs the specified operation, ECG 14 displays the local list of content, such as shown at position C in the drawing. After selecting content And local content, display screen information content, composed of brief descriptions of the content And image of reduced size and click "view/listen", such as shown at position D in the drawing, and after the operation with the button "view/listen", the AV player 15 starts playback of the content And, as shown in position E on the drawings. It should be noted that various types of information shown on the drawings in the positions A-D based on the content description of the metafile 41 playback control.

On Fig shows the sequence of processing corresponding to the operation mode of the structure. In the structure and, after selecting content by the user on the navigation page load displayed by the browser 11, and the operation of the acquisition (in particular, the operation with the button "buy and download" in position And Fig), the server 22 management client notified of the registration of the acquisition, the loader 12 receives the metafile 31 control loading, the content loads in accordance with the metafile 31 control loading. In response to the completion of the download content then request a license from a client 16 DRM server 26 MCC, and a license to provide playback from the server 26 DRM client 16 MCC. At this stage, the server 22 management client may determine that the device 10 receiving've already downloaded the content, so that at this point, the billing server performs 23 accrual account/calculation. In addition, after that, information about the end of the boot reflect on the navigation page load.

Then, after performing playback operations (in particular, the operation with the button "view/listen" at position D on Fig), for the already downloaded content, ECG 14 starts the AV player 15, and confirms the existence of any licenses for playback at the client 16 MCC of the AV player 15. In this case, a licence to reproduce already contained, so that the key KS of the content extracted from the license to reproduce and provide the AV player 15, and the AV player 15 reproduces the content (the decryption of the encrypted content and the decryption encoding).

It should be noted that when a licence to reproduce is not contained in the client 16 MCC for some reason (for example, when to obtain a license for playback is not possible due to obstacles when moving the hache data or the like), the client 16 MCC requests the license server 26 MCC. In this case, the flag confirmation at the time of use metafile 41 control playback off (described below with reference to Fig), the processing of obtaining the approval of the user does not perform, and receive the license.

On Fig shows an example of the description of the metafile 31 load control in accordance with the structure of the mode. Feature metafile 31 load control in accordance with the structure of the mode is that the ID of the license to reproduce, which is a valid license, is described in the item ID of the license.

On Fig shows an example of the description of the metafile 41 playback control in accordance with the structure of the mode. Feature metafile 41 playback control corresponding to the operation mode of the structure and, is that normal reproduction is described in the item about the type of license, and that the ID of the license to reproduce, which is a valid license, which is the same ID of the license, as described in the item ID of the license metafile 31 control loading described in the item ID of the license. In addition, the feature is that the flag confirmation at the time of use is turned off.

The mode structure b represents a service copy of the content is of the DVD once, and invoicing perform on stage, when the content is already loaded.

On Fig shows the transition of screens presented to the user in accordance with the mode of operation of the structure b. The browser 11 displays the first screen navigation download, and the user selects the content And to download on the navigation screen loading, so that, as shown in position a in the drawing, is shown a confirmation screen composed of images of reduced size corresponding to the content And a brief overview of the content And information such as "copy to DVD", "price 1000 yen", etc. and click "start", and after the operation with the button "start" on the confirmation screen, start downloading. The screen then goes to the thing that is, what is the boot process, as shown in position on the drawing.

After the download is complete, the contents And, after the user performs the specified operation, the local list of content, such as the one shown in position on Fig display with ECG 14. After selecting content And local content, display screen information content, composed of brief descriptions of the content And image of reduced size and click "copy", such as shown at position D in the drawing, and after the operations with the button "copy", AV player 15 starts exporting content And, as shown at position E in the drawing. It should be noted that various types of information in position And the drawing - in position D on the drawing displayed on the basis of the content of the description of the metafile 41 playback control.

On Fig shows the sequence of processing corresponding to the operation mode of the structure b. In the structure b, after selecting content by the user on the navigation page load displayed by the browser 11, and the operation of the acquisition (in particular, the operation with the button "buy and download" on Fig), the server 22 management client notified of the registration of the acquisition, the loader 12 receives the metafile 31 control loading, and the content loads in accordance with the metafile 31 control loading. In response to the completion of the download content, then request a license from a client 16 DRM server 26 MCC, and an export license grant from the server 26 DRM client 16 MCC.

At this stage, the server 22 management client may determine that the device 10 receiving've already downloaded the content, so that at this point, the server 23 accrual account/calculation performs the billing. In addition, after that, information about the end of the boot reflect on the navigation page load.

Then, after the export operation (castnet the operation, performed by using the button "copy" at position D on Fig) for the already downloaded content, ECG 14 starts the AV player 15, and confirms whether there is any export licenses from the client 16 MCC of the AV player 15. In this case, the export license is already included, so that the client 16 MCC allocates key KS to the content of export licenses and provide the AV player 15, the AV player 15 decrypts the encrypted content, the encoded data obtained as a result of this, is the device 17 external output coding method is changed accordingly and the data is encrypted again, and output to the output destination (block burn a DVD or the like).

It should be noted that when the export license is not contained in the client 16 MCC for some reason (for example, when an export license could not be obtained due to obstacles in the transmission data or the like), the client 16 MCC requests the license server 26 MCC. In this case, the flag confirmation when using the metafile 41 control playback off (described below with reference to Fig), the processing of obtaining the approval of the user is not performed, and receive the license.

On Fig shows an example of the description of the metafile 31 control the load according to the operating mode b. Feature metafile 31 control the load according to the operating mode of the structure b is that the ID of the license to export, which is a valid license, is described in the item ID of the license.

On Fig shows an example of the description of the metafile 41 playback control in accordance with the mode of operation of the structure b. Feature metafile 41 playback control in accordance with the mode of operation of the structure b is that the export to DVD described in the item type of license, and that the ID of an export license, which is valid licence that has the same ID of the license, as described in the item ID of the license metafile 31 control loading described in the item ID of the license. In addition, the feature is that the flag confirmation time off.

The mode structure is a service for rental viewing/listening of the content provided in the period of time possible playback, such as 7 nights 8 days, and the billing perform on the stage play download.

On Fig shows the transition of screens presented to the user in accordance with the mode of operation of the structure S. the Browser 11 displays the first screen navigation download, and the user selects the content And to download on the navigation screen download, so what Braz, that is, as shown in the drawing, display the confirmation screen, composed of images of reduced size corresponding to the content And a brief overview of the content And information such as "download", and click "DL", and after the operation with the button "DL" on the confirmation screen start downloading.
