Record it. This recorder 53 is used as local storage of the recording / reproducing apparatus 11.

The controller 54 controls the entire operation of the recording / reproducing apparatus 11 in accordance with an operation signal from the input unit 52.

The controller 54 includes a reproduction controller 61, a recording controller 62, and an acquisition unit 63. The reproduction controller 61, the recording controller 62, and the acquisition unit 63, for example, the controller 54 executes a program recorded in the recorder 53 as needed, or the optical disc 41 This is realized by executing a program read out from and supplied from the drive 51.

The reproduction controller 61 controls the reproduction of the content recorded on the optical disc 41 or the recorder 53. For example, the reproduction controller 61 decrypts the encrypted content as needed and supplies it to the display device 14. The recording controller 62 controls the recording of data such as content onto the optical disc 41. In addition, the acquisition unit 63 is content related to the content recorded on the optical disc 41 from the update information distribution server 12 or the service server 13 via the communication unit 55 and the communication network 15. And update information of the content.

Here, the update information is information to be notified to the user related to the content recorded on the optical disc 41. For example, predetermined information such as RSS (Resource Description Framework Site Summary) format or ATOM format is predetermined. It is a form of information.

For example, new content (for example, new content of a series) that can be viewed by downloading from the service server 13 is added to the update information as content related to the content recorded on the optical disc 41. And information for notifying the user of the fact that the data can be obtained. In addition, the update information includes information that a new subtitle or production video is added to the content recorded on the optical disc 41, information that the other source to which the source of supply is related, and the like are released. .

The communication unit 55 communicates with the update information distribution server 12 and the service server 13 through the communication network 15, and controls the data received from the update information distribution server 12 and the service server 13, and the like. 54, or data supplied from the controller 54 or the like is transmitted to another device.

In the optical disc 41, some of the plurality of related contents purchased by the user are recorded. For example, a user purchases one series disk (optical disk 41) which can be watched from the first to fifth episodes of an arbitrary series of dramas. In this series disk (optical disk 41), the moving picture data of the first picture already released at the time of purchase of the disk is recorded in advance from the moving picture data of the first to fifth episodes of the drama. Then, the moving picture data from the second to fifth pictures are sequentially released, downloaded from the service server 13, and recorded according to a standard such as EST (Electronic Sell Through).

When contents are added to the optical disc 41 in accordance with the standard of the EST, for example, as shown in FIG. 3, the user has a certificate 92 and a random data 93 in addition to the encrypted contents 91. , an optical disc 41 in which media ID (Identification) 94, Token 95, and AACS (Advanced Access Content System) data 96 are recorded in advance.

Here, the content 91 is, for example, the moving picture data of the first episode of the first episode to the fifth episode of the serial drama purchased by the user, and the certificate 92 is the first episode to the fifth episode. Is an electronic certificate indicating that moving picture data is available for purchase. This certificate 92 is issued by the server 101 corresponding to the service server 13.

The random data 93 is a random number recorded on the optical disc 41 by the server 101, and the media ID 94 is identification information unique to the optical disc 41. Token 95 is right information for the purpose of having the right to reproduce the content 91 and the content recorded on the optical disc 41, that is, the moving picture data from the first to fifth episodes of the drama. Token 95 is generated from predetermined data that server 101 has, random data 93, and media ID 94.

The AACS data 96 is data such as a decryption key (common key) determined according to the AACS standard, and is used when reproducing the content 91 and the content recorded on the optical disc 41. In other words, the AACS data 96 includes a decryption key used for decrypting the encrypted content 91 and additional content.

The user can reproduce the content 91 by inserting the purchased optical disc 41 into the recording / reproducing apparatus 102 corresponding to the recording / reproducing apparatus 11 and instructing the reproduction of the content 91.

At the time of reproduction of the content 91, the recording / reproducing apparatus 102 reads the certificate 92, the random data 93, the media ID 94, and the token 95 from the optical disc 41, and reads it out. Based on these information, it is confirmed that the content 91 is the reproducible content purchased regularly. More specifically, the recording / reproducing apparatus 102 hashes the data of the predetermined value, the certificate 92, the random data 93, and the media ID 94 recorded in the recording / reproducing apparatus 102 in advance. A value is computed and the Token 95 is compared with the value obtained by the operation.

When the recording and reproducing apparatus 102 confirms that the hash value and the value of the Token 95 coincide with each other and is normally purchased content, the recording / reproducing apparatus 102 also reads the content 91 and AACS data 96 from the optical disk 41. . The recording and reproducing apparatus 102 decodes the content 91 using the AACS data 96 and reproduces the content 91.

After the user purchases the optical disc 41, when the newly remaining content, that is, the content added to the optical disc 41 purchased by the user, becomes available for download, the recording / reproducing apparatus 102 instructs the user. The content is downloaded from the server 101 accordingly. The recording and reproducing apparatus 102 records the downloaded content on the optical disk 41. Thereby, the user can use the optical disc 41 to watch not only the content 91 but also all the purchased contents, for example, all the first to fifth episodes of the drama.

Hereinafter, the content previously recorded on the optical disc 41 is also called recorded content, and the content added to the optical disc 41 purchased by the user is also called additional content.

When the user purchases the optical disc 41 in which the content 91 as the recorded content and the certificate 92 of the additional content are recorded, the user inserts the optical disc 41 into the recording / reproducing apparatus 11. And recorded content can be reproduced. When the optical disc 41 is inserted and the operation signal instructing reproduction of the recorded content is supplied from the input unit 52, the recording and reproducing apparatus 11 performs the reproducing process to reproduce the recorded content.

Hereinafter, with reference to the flowchart of FIG. 4, the reproduction process by the recording / reproducing apparatus 11 is demonstrated.

In step S11, the drive 51 reads out meta information of the recorded content from the optical disc 41 inserted in the recording / reproducing apparatus 11. Here, the meta information to be read is meta information of recorded content recorded on the optical disc 41.

For example, the meta information includes content information, feed uniform resource locator (URL), access frequency information, access authentication information, org ID, and disc ID.

The content information is information that includes the title name of the recorded content, the jacket image of the title, that is, the so-called thumbnail image, and the like, and the content information displays the library information, which is a list of the contents reproduced in the past, on the display device 14. It is used when

The feed URL is location information described in the form of a URL indicating the recording destination of the update information, that is, the location where the update information in the update information delivery server 12 is recorded. Therefore, the feed URL becomes different information for every title of content. Hereinafter, the location information described by the URL method is simply called URL.

The access frequency information is information indicating the timing and frequency with which the recording and reproducing apparatus 11 accesses the update information distribution server 12, and more specifically, the update information. For example, the access frequency information is accessed once a week and at 12:00. Information and the like. In addition, the access authentication information is information necessary for authentication of a user performed when accessing the update information of the recording / reproducing apparatus 11, for example, a user of a user who is registered in advance in the update information distribution server 12. ID, password, information indicating the authentication method, and the like. In addition, org ID is identification information which specifies the provider of the title of the recorded content, and disc ID is identification information which specifies the title of the content.

When the drive 51 reads the meta information from the optical disk 41, the drive 51 supplies the read meta information to the controller 54, and the controller 54 records the meta information supplied from the drive 51. Supplies).

In step S12, the recorder 53 records the meta information supplied from the controller 54 in accordance with the instruction of the controller 54.

In step S13, the reproduction controller 61 of the controller 54 reproduces the recorded content in accordance with the user's operation. That is, the reproduction controller 61 causes the drive 51 to read the contents from the optical disc 41 in accordance with the operation signal from the input unit 52, and acquires the read contents from the drive 51. Then, the reproduction controller 61 performs predetermined processing such as decoding on the content supplied from the drive 51 to supply it to the display device 14, and causes the display device 14 to display the content. .

More specifically, at the time of reproduction of the recorded content, the reproduction controller 61 uses the certificate, random data, media ID, and Token read from the optical disc 41, so that the content to be reproduced is normal. It is checked whether or not it is content. The reproduction controller 61 also decodes the content recorded using the AACS data read from the optical disc 41. In addition, the playback controller 61 also performs a process such as pausing or stopping the playback of content in accordance with the user's operation.

In step S14, the reproduction controller 61 determines whether or not the reproduction of the recorded content is terminated.

For example, when the user is instructed to stop playback of the recorded content, it is determined in step S14 that the playback ends.

If it is determined in step S14 that the reproduction is not to end, the process returns to step S13 and the above-described process is repeated. In more detail, in step S13, for the content confirmed as the regular content once, no confirmation processing is performed again, but only the processing necessary for reproduction of the content or the like is performed.

In contrast, when it is determined in step S14 that the reproduction is terminated, each unit of the recording / reproducing apparatus 11 ends the processing that is being performed, and the reproduction processing ends.

As described above, when the optical disc 41 is inserted, the recording and reproducing apparatus 11 reads the meta information from the optical disc 41 and records it in the recorder 53.

As described above, by reading and recording the meta information, the update information delivery server 12 can be accessed using the feed URL included in the meta information, and the update information can be obtained. That is, even when the optical disc 41 is not inserted into the recording and reproducing apparatus 11, the recording and reproducing apparatus 11 can obtain the update information and present it to the user. Accordingly, the user can easily and quickly know the information related to the recorded content or the additional content, such as whether the additional content has been released (released) and made available for viewing, without requiring any special operation.

When the meta information of the content recorded on the optical disc 41 is recorded in the recorder 53 by the reproduction process, the recording / reproducing apparatus 11 distributes the update information based on the access frequency information included in the meta information. The server 12 is periodically accessed to obtain update information. When the additional content is newly recorded in the service server 13 and the additional content is in a viewable state, the recording / playback apparatus 11 acquires the additional content from the service server 13 based on the obtained update information.

In addition, the update information distribution server 12 and the service server 13 also perform a process of providing update information and additional content to the recording / playback apparatus 11 in response to a request from the recording / playback apparatus 11.

Hereinafter, with reference to the flowchart of FIG. 5, the content update process by the recording / playback apparatus 11, the update information transmission process by the update information distribution server 12, and the content provision process by the service server 13 are described. Explain.

In step S41, the acquisition unit 63 of the recording / playback apparatus 11 determines whether to obtain update information based on the access frequency information included in the meta information of the recorded content recorded in the recorder 53. Determine. For example, the acquisition part 63 always judges that acquisition information is acquired, when the timer operation | movement is always performed and it is time to access update information specified by the access frequency information.

More specifically, when the time for accessing the update information is accessed, the content specified by the org ID and the disc ID included in the meta information, that is, the content of the optical disc 41 from which these IDs are read, is being played back. Is determined that no update information is obtained. Thereby, contention with the process of acquiring the additional content and the process of acquiring update information indicated by the user operation can be avoided.

Similarly, when it is time to access the update information, even when a process of a function of managing the recorder 53 such as the deletion of the content recorded in the recorder 53 is being executed, in order to avoid contention of the update, the update information It is determined that is not obtained.

If it is determined in step S41 that no update information is obtained, the process returns to step S41 and the determination process is repeated until it is determined that the update information is obtained.

In contrast, when it is determined in step S41 that the update information is acquired, in step S42, the acquisition unit 63 requests the update information delivery server 12 to transmit the update information. In other words, the acquisition unit 63 reads the feed URL and the access authentication information included in the meta information from the recorder 53, and updates the feed URL and the access authentication information via the communication unit 55 to the update information distribution server 12. ), The recording destination of the update information indicated by the feed URL is accessed.

If the recording / reproducing apparatus 11 requests update information from the update information distribution server 12, in step S61, the update information distribution server 12 records the update information according to the request of the recording / reproducing apparatus 11. (11).

That is, the update information distribution server 12 receives the feed URL and the access authentication information transmitted from the recording / reproducing apparatus 11, and uses the received access authentication information to determine whether the user is a regular user registered in advance. Authenticate whether When authentication is performed, the update information delivery server 12 transmits the update information specified by the received feed URL to the recording / playback apparatus 11 via the communication network 15, and the update information transmission process ends.

For example, when the update information recorded by the update information distribution server 12 is information in ATOM format, and more specifically, when update information is included in ATOM format transmission information, the transmission information is shown in FIG. 6. Information on each item shown in the table is included.

In FIG. 6, each item contained in transmission information is shown by the left column in the figure, and description of the information of each item is shown by the right column in the figure. That is, in the transmission information transmitted from the update information distribution server 12 to the recording / reproducing apparatus 11, an item of "feed" in which other items are stored is set as the root element, and the item "feed" is set to "title". Information of each item of "," id "," link "," author "," updated ", and" entry "is stored.

In the item "title", a character string indicating the title of the recorded content of the optical disc 41 is stored, and in item "id", an ID (identification information) indicating that it is update information about the title of the recorded content is stored. . In the identification information stored in this item "id", the org ID and disc ID contained in the meta information of the recorded content of the optical disc 41 are arranged.

The item "link" also stores a URL indicating a recording destination of a web page from which detailed information on the title of the recorded content is obtained. The item "author" stores information on the source of supply of the recorded content of the optical disc 41, and the item "updated" stores information indicating the update date and time of transmission information. The item "entry" also stores information of each item of the entry included in the transmission information.

Here, the entry refers to one piece of update information that is notified to the user, such as an additional content being released (released) and made available for download, and when the transmission information includes a plurality of pieces of update information, the item "feed" includes: The item "entry" is stored as many as the number of update information.

The item "entry" stores information of each item of "title", "link", "id", "published", "updated", and "summary".

The item "title" stores a character string indicating update information, and the item "link" stores information indicating a link destination for update information. The item "id" stores an ID for identifying update information, and the items "published" and item "updated" store information indicating the date and time of issue of the update information and the date and time of the update. The item "summary" also stores a string representing the outline of the update information.

The transmission information contained in each item shown in FIG. 6 becomes the information shown in FIG. 7 specifically ,. In the transmission information of FIG. 7, in the figure, in the upper part K11, information of each item of "title", "id", "link", "author", and "updated" stored in the item "feed" is shown. Included. For example, the letters "70" and "1" in the tag "id" included in the portion of K11 indicate an org ID and a disc ID included in the optical disk 41, respectively.

The K12 to K14 portions of the transmission information each include an entry of one update information, and each entry includes "title", "link", "id", "published", and "entry" in the item "entry". information about each item of "update", and "summary" is included.

For example, the entry included in the part of K12 is the update information whose title is the character string "secondized release" contained in the tag "title". In addition, the tag "link" of this entry includes information indicating the type of information of the link destination and a link destination URL as a link destination for the update information. In the tag "link" of the entry contained in the part of K12, the link URL "http://some-studio.com/est/28/1/2nd/package.xml" is shown, and the tag In "link", the character "pack" which shows the kind of information of the link destination is contained. This character "pack" indicates that the information obtained by accessing the link destination is package information required for obtaining additional content.

For example, the entry contained in the part of K14 becomes update information whose title is the character string "guidance of 28 season II release" contained in the tag "title".

The tag "link" of this entry contains the character "info" indicating the type of information of the link destination regarding the update information. This character "info" refers to content whose information obtained by accessing the link destination in the tag "link" relates to the recorded content recorded on the optical disc 41, for example, the content whose title is "28 Season II". This indicates that it is a web page of a shopping site where you can purchase. In the tag " link " of the entry of the portion of K14, the URL " http: //some-studio.com/shop/28/2/index.html" of the link associated with the update information is shown.

In the update information delivery server 12, for example, update information (transmission information) shown in FIG. 7 is recorded, and the update information is updated at any time. That is, entries of new update information are sequentially added to the transmission information. When the update information distribution server 12 receives the feed URL and the access authentication information transmitted from the recording / reproducing apparatus 11, and authenticates the user, the update information distribution server 12 records the updating information recorded, more specifically, the transmission information. (11).

Returning to the description of the flowchart of FIG. 5, when update information is transmitted in step S61, in step S43, the communication unit 55 of the recording / playback apparatus 11 updates the update information transmitted from the update information distribution server 12. Receive The communication unit 55 then supplies the received update information to the acquisition unit 63 of the controller 54.

In step S44, the acquisition unit 63 compares the update information supplied from the communication unit 55 with the update information acquired in the past recorded in the recorder 53, is newly acquired, and supplied from the communication unit 55. It is determined whether there is a new entry in the updated update information.

For example, the acquisition part 63 acquires the transmission information (update information) shown in FIG. 7 newly from the update information delivery server 12, and it is K12 of FIG. 7 to the transmission information recorded in the recorder 53. FIG. When the entry of the part of and the entry of the part of K13 are included, the acquisition part 63 determines that there is a new entry. That is, since newly acquired transmission information includes the entry shown in the part of K14 which has not been acquired so far, new update information stored in the entry is obtained.

When it is determined in step S44 that there is no new entry, new update information has not been obtained, so the processing of steps S45 to S52 is skipped, and the content update processing ends.

On the other hand, when it is determined in step S44 that there is a new entry, in step S45, the acquisition unit 63 supplies the recorder 53 with the acquired new update information. In addition, as the update information, the transmission information immediately shown in FIG. 7 may be recorded, or only the newly acquired update information in the obtained transmission information may be recorded.

In step S46, the acquisition unit 63 determines whether there is an entry of package information in the new entry included in the update information newly acquired from the update information distribution server 12, more specifically, the transmission information.

For example, the transmission information shown in FIG. 7 is newly acquired, and it is determined that the entry of the portion of K13 and the entry of the portion of K14 in the transmission information are new entries in step S44. In this case, the tag " link " in the entry of the part of K13 includes the character " pack ", which indicates that the type of the link destination information is the package information, and therefore it is determined in step S46 that there is an entry of the package information.

If it is determined in step S46 that there is no entry of package information, the processing of steps S47 to S52 is skipped, and the content update processing ends.

In contrast, when it is determined in step S46 that there is an entry of package information, in step S47, the acquisition unit 63 requests the service server 13 to transmit package information.

For example, when the entry of the part of K13 of FIG. 7 becomes an entry of the package information among the new entries, the acquisition part 63 selects the URL of the link destination relating to the update information in the tag "link" of the entry, By transmitting to the service server 13 via the communication unit 55, the recording destination of the information indicated by the URL is accessed.

When the recording / reproducing apparatus 11 requests the package information from the service server 13, in step S71, the service server 13 sends the package information to the recording / reproducing apparatus 11 in accordance with the request of the recording / reproducing apparatus 11. Send. That is, the service server 13 receives the URL transmitted from the recording / reproducing apparatus 11, and transmits the package information specified by the received URL to the recording / reproducing apparatus 11 via the communication network 15. .

For example, when the package information recorded by the service server 13 is information described by XML (Extensible Markup Language), the package information includes the information of each item shown in FIG.

In FIG. 8, each item contained in package information is shown by the left column in the figure, and description of the information of each item is shown by the right column in the figure. That is, in the package information, an item of "package" in which other items are stored is set as the root element, and in the item "package", each item of "title", "id", "description", and "file" is set. Information is stored.

The item "title" stores a character string indicating the contents of the package information, and the item "id" stores an ID (identification information) for specifying the package information. The identification information stored in this item "id" becomes the same value as ID which identifies the update information which specified the package information as a link destination. This makes it possible to identify whether the package information is information specified by the URL included in which update information.

In the item "description", a string indicating the details of the contents of the package information is stored. In addition, the item "file" stores the information of each item about the file which comprises the package represented by package information.

Here, the files constituting the package are, for example, moving image data of additional content, files required for reproducing the additional content, and the like. When the package information includes information of a plurality of files, the item "package" The item "file" is stored as many as the number of files.

The item "file" stores the information of each item of "title", "id", "size", "checksum", "url", and "dest".

The item "title" in the item "file" stores a string representing the content of the file, and the item "id" stores an ID for identifying (specifically) the file. In item "size" and item "checksum", the size and checksum of the file are stored, respectively.

The item "URL" stores the file acquisition destination, that is, the URL of the recording destination where the file is recorded, and the item "dest" indicates the storage destination after the file acquisition by the recording / reproducing apparatus 11. The information is stored.

Specifically, the package information which includes each item shown in FIG. 8 becomes the information shown in FIG. 9, for example. In the package information of FIG. 9, in the figure, the part of the upper K31 contains the information of each item of "title", "id", and "description" stored in the item "package".

For example, the character "pack / 3rd" in the tag "id" contained in the part of K31 has shown the ID which specifies the package information stored in the item "id". The character " pack / 3rd " representing this ID is the same as the ID " pack / 3rd " for identifying the update information in the entry of the portion of K13 in FIG. have.

In addition, the information of each item of one file which comprises a package is shown by K32 and K33 part of package information, respectively.

For example, the file represented by the part of K32 is the URL "http://some-studio.com/est/28/1/3rd/bumf.from1-2.to3.xml contained in the tag" url ". Is a file obtained by accessing "," and the storage destination of the file is a position on the recorder 53 indicated by the character "bumf.from1-2.to3.xml" included in the tag "dest".

More specifically, in the tag " dest ", a path on the recorder 53 may be designated as a file storage destination, and a path on the optical disk 41 may be designated. For example, in the tag "dest", when the character which shows the storage destination of a file is arrange | positioned after the character "buda", the character which shows the storage destination has shown the path | route on the recorder 53. As shown in FIG.

More specifically, the character "bumf.from1-2.to3.xml" indicating the storage destination following the character "buda" in the tag "dest" of the part of K32 indicates the path and file name of the file to be saved. The acquired file is stored in the directory of the name of the value of disc ID in the directory of the name of the value of org ID in the meta information of the optical disc 41 belonging to the root directory on the recorder 53. It is written as "bumf.from1-2.to3.xml".

In the tag " dest ", when a character indicating the destination of the file is arranged after the character " disc ", the character indicating the destination of the file indicates a path on the optical disk 41. As shown in FIG. In the tag " dest " of the K32 portion, only the character " buda " that designates a path on the recorder 53 is included, so that a file obtained by the URL included in the portion of K32 is not recorded on the optical disk 41. FIG. Do not.

For example, the file acquired by the URL included in the part of K32 is called the BUMF (Binding Unit Manifest File) required when playing back the recorded content recorded on the optical disc 41 and the additional content. It will be a file. This BUMF contains information indicating the path and the like of the recorder 53 in which the additional content is recorded.

For example, the file represented by the part of K33 becomes a file which shows the play list of additional content. This file is a file obtained by accessing the URL "http://some-studio.com/est/28/1/3rd/3rd.mpl" contained in the tag "url" of the part of K33. The destination of the file is a position on the recorder 53 indicated by the character "addition / 3rd.mpl" included in the tag "dest", or the character "BDMV / PLAYLIST / contained in the tag" dest ". 00030.mpls ".

In other words, when the additional content is downloaded and recorded in the recorder 53, it is recorded at the position indicated by the character "addition / 3rd.mpl" and is also recorded on the optical disc 41 from the recorder 53. Is recorded at the position indicated by the character " BDMV / PLAYLIST / 00030.mpls ".

For example, the package information shown in FIG. 9 is recorded in the service server 13, and the service server 13 receives a URL transmitted from the recording / reproducing apparatus 11, and receives the package information from among the recorded package information. Package information specified by one URL is transmitted to the recording / reproducing apparatus 11.

Returning to the description of the flowchart of FIG. 5, when package information is transmitted from the service server 13 to the recording / reproducing apparatus 11 in step S71, the communication unit 55 of the recording / reproducing apparatus 11, in step S48, The package information transmitted from the service server 13 is received and supplied to the controller 54.

When the package information is supplied from the communication unit 55, the acquisition unit 63 of the controller 54 supplies the package information to the recorder 53 and records the package information, and the status of the additional content specified by the package information. (status) information is recorded in the recorder 53.

Here, the status information of the additional content means any of the states in which the additional content has not been downloaded yet, has been downloaded and recorded in the recorder 53, or further recorded in the optical disc 41 from the recorder 53. Refers to information indicating whether the state of.

The status information is set to "not yet downloaded" when the additional content is not downloaded, and set to "downloaded" when the additional content is recorded in the recorder 53, and the additional content is When recorded on the optical disk 41, it is set to " disc recorded. &Quot; Therefore, the status information of the additional content specified by the package information received in step S48 is "undownloaded" at this point in time.

The status information is recorded in the recorder 53 in association with an ID for specifying the package information, for example, ID " pack / 3rd " included in the portion K31 of the package information in FIG. Since this ID is also included in the update information in which the package information is designated as a link destination, the package information and update information corresponding to the status information are specified from the ID associated with the status information.

In step S49, the acquisition unit 63 of the controller 54 accesses the recording destination of the additional content indicated by the URL included in the package information, and requests the service server 13 to transmit the additional content.

For example, the acquisition part 63 transmits the URL contained in the tag "URL" of the part K33 of FIG. 9 to the service server 13 via the communication part 55, and requests transmission of additional content. . The acquisition unit 63 also accesses the URL included in the item "file" of the package information for another file different from the additional content indicated by the package information, for example, a file such as BUMF, and the service. The server 13 is requested to send a file.

If the recording / playback apparatus 11 requests the service server 13 to transmit additional content, in step S72, the service server 13 records the additional content according to the request of the recording / playback apparatus 11; Is sent to, the content providing process ends.

That is, the service server 13 receives the URL transmitted from the recording / reproducing apparatus 11, and transmits the additional content and the BUMF specified by the received URL to the recording / reproducing apparatus 11 via the communication network 15. do.

When the additional content is transmitted from the service server 13 to the recording / playback apparatus 11, in step S50, the communication unit 55 of the recording / playback apparatus 11 receives the additional content transmitted from the service server 13, Supply to the controller 54. In addition, when files such as BUMF are transmitted from the service server 13, the communication unit 55 also receives these files and supplies them to the controller 54. The acquisition unit 63 of the controller 54 supplies the additional content or BUMF to the recorder 53 when additional content or BUMF is supplied from the communication unit 55.

In step S51, the recorder 53 records the additional content supplied from the controller 54 and a file such as a BUMF. A file such as additional content recorded in the recorder 53 is recorded at a position indicated by a path stored in the item "dest" in the package information. In addition, the additional content acquired from the service server 13 is previously encrypted by the encryption key corresponding to the decryption key contained in the AACS data on the optical disc 41.

In step S52, the acquisition unit 63 updates the status information of the additional content recorded in the recorder 53 from "undownloaded" to "downloaded", and the content update process ends.

As described above, the recording and reproducing apparatus 11 accesses the feed URL included in the meta information and acquires the update information. The recording and reproducing apparatus 11 acquires and records the additional content upon knowing that the additional content is uploaded to the service server 13 and can be viewed based on the entry of the package information included in the obtained update information.

As described above, by acquiring the update information using the feed URL read and recorded from the optical disc 41, information related to the recorded content of the optical disc 41, in particular, newly added and made viewable The information can be obtained without causing the user to perform special operations. Therefore, the information related to the title of the optical disc 41 and the information about the additional content can be presented to the user more simply and quickly.

In addition, when the acquired update information includes an entry of package information, by acquiring the package information and acquiring additional content using the acquired package information, additional content can be acquired without causing a user to perform special operations. Can be. As a result, the user can easily and quickly view the additional content without inserting the optical disc 41 into the recording / reproducing apparatus 11 or confirming the update of the content on the web page. As a result, it is possible to promote the use of the content.

Further, even if the user does not insert the optical disc 41 into the recording / reproducing apparatus 11, the information relating to the contents is obtained by the recording / reproducing apparatus 11, so that the provider of the contents can provide information about the contents provided by the user. The user can be notified simply and reliably by the update information distribution server 12.

The optical disc 41 also records a recorded content, a feed URL, and a token as reproduction right information indicating that the recorded content and the additional content can be reproduced. Therefore, the user can simply purchase a plurality of related contents, including additional contents that have not been released yet, in one batch simply by purchasing one optical disc 41, in one batch. .

In addition, when the additional content is released sequentially, the update information and the additional content are acquired without requiring any operation, so that the release of the additional content can be known simply and quickly, and the additional content can be viewed. .

When each of the meta information of the plurality of recorded contents read from each of the plurality of optical discs 41 is recorded in the recorder 53, the content update process described with reference to FIG. 5 for each of these recorded contents. Is performed. In other words, the content update process is performed at the timing of access for each recorded content. In addition, the content update process may be started immediately after the last content update process has been completed, or may be performed at regular time intervals.

If the additional content is recorded in the recorder 53 in the same manner as described above, the user can watch the additional content.

Next, with reference to the flowchart of FIG. 10, the additional content reproduction process which is the process which the recording / playback apparatus 11 reproduces the downloaded additional content is demonstrated.

When the user operates the input unit 52 and instructs the display of the menu screen while the optical disc 41 is not inserted into the recording / reproducing apparatus 11, the user inputs the controller 54 from the input unit 52 to the controller 54. The operation signal according to the operation is supplied.

When an operation signal is supplied to the controller 54, in step S111, the controller 54 causes the display device 14 to display a menu screen based on the meta information and update information recorded in the recorder 53.

Thereby, the menu screen shown in FIG. 11 is displayed on the display apparatus 14, for example. In the menu screen shown in FIG. 11, an item 131 for selecting the contents of the optical disc inserted in the recording / reproducing apparatus 11, an image 132-1 relating to the contents of the optical disc reproduced in the past, and an image ( 132-2), the library information is displayed. The menu screen also displays a cursor 133 for selecting any one of the item 131 and the images 132-1 and 132-2.

When a predetermined optical disc 41 is inserted into the recording / reproducing apparatus 11, the controller 54 causes the meta data to be read from the optical disc 41 inserted into the drive 51, and the read meta information is read. On the basis of this, the title name of the content recorded on the optical disc 41 is displayed on the item 131. When the title of the content is displayed in the item 131, the user can select the item 131 by the cursor 133 and play the content.

In addition, the images 132-1 and 132-2 on the menu screen are images representing the contents of one optical disc 41, respectively, and are read from the optical disc 41 and recorded in the recorder 53. The information is displayed based on the content information included in the meta information.

On the right side of the image 132-1 in the figure, the title name "28 season I" of the content represented by the image 132-1 is displayed. In the title name diagram, the lower side shows the last acquired content. Title "Guide of 28 Season II Release" indicating the related information, that is, the content of the update information, and the character "NEW" indicating that it is unconfirmed update information are displayed.

The title of the content on the right side of the image 132-1 is displayed based on the content information of the meta information recorded in the recorder 53, and the title of the update information is updated to the update information recorded in the recorder 53. Displayed on the basis of For example, a string stored in the item "title" of the entry of the K14 portion of the update information in FIG. 7, that is, the string "28 season II release guide" in the tag "title" is the menu screen as the title of the update information. Is displayed.

As in the image 132-1, in the drawing of the image 132-2, the title name "Mona Lisa Code" of the content represented by the image 132-2 is displayed on the right side. On the lower side, a title "addition other than the production video" indicating the content of the finally obtained update information is displayed.

Hereinafter, when it is not necessary to distinguish between the image 132-1 and the image 132-2 individually, it is simply called the image 132. FIG.

In addition, the user operates the input unit 52 to move the cursor 133, selects the image 132 by the cursor 133, and displays a list of update information of the content corresponding to the image 132. Can be displayed.

For example, when the image 132-1 is selected by the user and the display of the list of update information of the content represented by the image 132-1 is instructed, the controller 54 displays the image 132-1. The list of update information is displayed on the display device 14 on the basis of the update information of the content represented by and status information.

For example, when the update information of the content represented by the image 132-1 is the update information shown in FIG. 7, the controller 54 lists the update information shown in FIG. 12 on the display device 14. Is displayed.

In the list of update information in FIG. 12, display fields 161-1 to 161-3 in which update information (entry) of parts of K14 to K12 in FIG. 7 are displayed are set together with the image 132-1. . For example, in the display field 161-1, the title "Guide of 28 season II release" of the update information and the content "season II was released. The season II was released." Becomes a character string in tag "title" of the part of K14 of FIG. 7, and a character string in tag "summary".

Further, in the display field 161-1, the character "notification INFO" indicating that the update information is information of the content related to the recorded content is displayed. This character "notification" is displayed when the type of information of the link destination in the tag "link" in the entry of the corresponding update information in FIG. 7, that is, the entry of the portion of K14 is "info".

In the display field 161-1, a button 162 that is operated when accessing the URL in the tag "link" of the part of K14 is displayed. For example, when the button 162 is operated, the display device 14 can purchase content whose title is "28 season II" notified by the update information displayed in the display field 161-1. The web page is displayed.

When the type of the information of the link destination in the tag "link" in the entry is "pack", the entry is an entry for specifying package information as a link destination, and therefore, in the display field, it indicates that it is update information about additional content. The letter "additional content" is displayed.

In the display field 161-1, the updated date and time "2008/04/01 00:00" of the update information is displayed, and the date and time, the tag "updated" of the part K14 of the update information of FIG. It is a date and time indicated by.

For example, in the display field 161-3, the title "Section 2 release" of the update information, the content "Section 2 was released" of the update information, and the updated date and time "2008/03" of the update information / 01 00:00 "is displayed.

In the display field 161-3, a character " additional content " indicating that the update information is related to the additional content and a character " disc recorded " representing the status information of the additional content are displayed. In addition, in the display field 161-3, a button 163 operated when downloading the additional content is also displayed. The button 163 is displayed when the status information of the additional content is "undownloaded" or "disc recorded".

When it is not necessary to distinguish each of the display columns 161-1 to 161-3 individually, it is simply called the display column 161. The update information displayed in the display field 161 is arranged in order from top to bottom in FIG. 12 in order from the new date and time of the update date.

Further, below the image 132-1 in FIG. 12, the additional content indicated by the update information displayed in the display field 161, more specifically, the additional content whose status information is "downloaded" is stored in the optical disc ( A button 164 to be operated when recording to 41 is set. In the drawing of the button 164, a button 165 that is operated when switching the display on the display device 14 to the menu screen of FIG. 11 is set on the lower side.

As described above, by displaying the list of update information on the display device 14, the user can easily and quickly know the update status of the content without inserting the optical disc 41 into the recording / playback device 11. .

And by confirming the status information displayed on the display field 161, it can also be understood that new additional content is downloaded and can be viewed. Therefore, when the user intends to watch newly downloaded additional content, the recording and reproducing apparatus 11 inserts the optical disc 41 in which the certificate and the token of the additional content are recorded.

Returning to the description of the flowchart of FIG. 10, when the optical disc 41 is inserted into the recording / playback apparatus 11, in step S112, the playback controller 61 performs the VFS based on the BUMF recorded in the recorder 53. Configure (Virtual File System).

Here, the VFS is a virtual file system defined by the Blu-ray Disc standard, and is a virtual file system that treats the recorded content on the optical disc 41 and the additional content recorded in the recorder 53 as one content. .

For example, the reproduction controller 61 treats the recorded content and the additional content as one content by referring to the path and the like of each content shown in the BUMF recorded in the recorder 53.

The BUMFs for constructing the VFS differ from each other by the status information of the additional content, that is, the place where the additional content is recorded. For example, when the first episode of a series of dramas is recorded content, and the second episodes and third episodes are additional contents, are the second episodes and third episodes recorded on the optical disc 41 or the recorder? By recording at 53, different BUMFs are required to reproduce the content.

That is, as shown in Fig. 13, when the second and third episodes (additional content) are recorded on the recorder 53, the first episode is recorded on the optical disc 41 in order to configure the VFS. The BUMF which designates to add 2nd and 3rd episodes is needed. In this case, the paths of the second and third episodes on the recorder 53 are recorded in the BUMF.

In addition, when the first and second episodes are recorded on the optical disc 41 and the third episode is recorded on the recorder 53, the first and second episodes are used to construct the VFS. The BUMF, which was recorded in the document and has been designated to add the third episode, is required. In this case, the third pass on the recorder 53 is recorded in the BUMF.

In the case where the first to third episodes are recorded on the optical disc 41, there is no need to configure the VFS, so that the BUMF is not used for reproduction of the first to third episodes.

When the second and third episodes become additional content, two BUMFs are required, but these BUMFs are obtained by accessing the URL stored in the item "file" of the package information.

For example, as shown in Fig. 14, in the state where additional contents of the second and third episodes are recorded in the recorder 53, the recording / reproducing apparatus 11 constitutes a VFS, thereby making it possible to obtain the first image. The contents of the first to third episodes can be played back.

However, if the additional content of the second episode is deleted from the recorder 53, the additional content of the second episode does not exist in the recording destination indicated by the path of the second episode represented by BUMF, so that recording and reproduction The apparatus 11 cannot configure the VFS, so that only the first episode recorded on the optical disc 41 can be reproduced.

When the additional content of the second episode is deleted, the status information of the additional content is updated to "undownloaded", so that the second episode can be downloaded. Thereafter, when the recording / reproducing apparatus 11 downloads the second episode (additional content) again, the recording / reproducing apparatus 11 is in a state where the second episode exists in the recording destination of the second episode represented by BUMF. Is again in a state in which the first to third episodes can be reproduced.

If the second and third episodes are recorded on the optical disc 41, the first to third episodes can be reproduced without the need for BUMF.

The first episode is recorded on the optical disc 41, and a BUMF to which the third episode is added is prepared, and the recording / playback apparatus 11 can reproduce the first episode and the third episode by using the BUMF. You may have it.

Returning to the description of the flowchart in FIG. 10, when the VFS is configured, and the user instructs playback of the additional content, in step S113, the playback controller 61 supplies the operation from the input unit 52 in accordance with the user's operation. Based on the signal, additional content is played.

That is, the reproduction controller 61 refers to the path of the additional content indicated by the BUMF recorded in the recorder 53 and reads out the additional content from the position of the recorder 53 indicated by the path. The reproduction controller 61 also reads the certificate of the additional content, random data, media ID, Token, and AACS data from the optical disk 41 via the drive 51.

Then, the playback controller 61 checks whether or not the additional content to be played back is the content acquired by the regular user, using the certificate, the random data, the media ID, and the Token. Then, AACS The additional content is decoded using the data and supplied to the display device 14. The display device 14 displays additional content from the playback controller 61.

In step S114, the playback controller 61 determines whether or not the reproduction of the additional content is finished. For example, if the user is instructed to stop the playback of the additional content, it is determined in step S114 that the playback ends.

If it is determined in step S114 that playback is not to end, the process returns to step S113 and the above-described process is repeated.

In contrast, when it is determined in step S114 that the reproduction is finished, the respective portions of the recording / reproducing apparatus 11 end the processing that is being performed, and the additional content reproduction processing ends.

In the above-described manner, the recording / playback apparatus 11 constructs a virtual file system using the BUMF, and plays back the downloaded additional content.

As described above, by configuring the virtual file system and reproducing the additional content recorded in the local storage (recorder 53) of the recording / reproducing apparatus 11, the user can record the content recorded on the optical disc 41. In addition, the content downloaded from the service server 13 can be viewed and enjoyed.

In the above, it was demonstrated that when update information is acquired, package information and additional content are acquired without requiring a user's operation. Alternatively, the package information and the additional content may be acquired when instructed by the user who confirmed the update information.

In such a case, after confirming the list of update information displayed on the display device 14, the user inserts the optical disc 41 corresponding to the additional content to be acquired into the recording / reproducing device 11, Instruct the acquisition. Then, the acquisition unit 63 of the recording and reproducing apparatus 11 is, for example, the BD-J (BD (Blu-ray Disc (registered trademark of Sony Corporation)) from the optical disc 41 via the drive 51). -The program of Java (registered trademark) is read and executed, and package information and additional content are acquired from the service server 13 using update information.

By the way, in the recording / reproducing apparatus 11, in order to prevent the shortage of the recording area of the recorder 53 caused by recording a lot of additional content in the recorder 53, the additional content recorded in the recorder 53 is stored in the optical disc. It is made to be able to record in (41).

Hereinafter, with reference to the flowchart of FIG. 15, the additional content recording process by the recording / reproducing apparatus 11 will be described.

When the user operates the input unit 52 and instructs the display of the menu screen while the optical disc 41 is not inserted into the recording / reproducing apparatus 11, the user inputs the controller 54 from the input unit 52 to the controller 54. The operation signal according to the operation is supplied.

When the operation signal is supplied to the controller 54, the controller 54 displays the menu screen of FIG. 11, for example, based on the meta information and update information recorded in the recorder 53 in step S141. Mark it.

After the menu screen is displayed, an operation is performed on the input unit 52 to display the list of update information in FIG. 12, and the display device 14 is operated by operating the button 164 and the controller 54 in accordance with the user's operation. A message prompting the insertion of the optical disc 41 is displayed.

Then, in response to the message, when the user inserts the optical disc 41 into the recording / reproducing apparatus 11, in step S142, the recording controller 62, based on the package information recorded in the recorder 53, receives the optical disc. The additional content is recorded on the disc 41.

That is, the recording controller 62 obtains the designated additional content from the recorder 53 and supplies it to the drive 51. Then, the recording controller 62 passes the recording destination of the additional content specified by the item "dest" in the item "file" corresponding to the additional content to be recorded in the package information recorded in the recorder 53. Read

This path is, for example, a path "BDMV / specified by a tag on the side of the two tags" dest "of the part of K33 of FIG. 9 that contains the letter" disc "which designates the path on the optical disc 41. FIG. PLAYLIST / 0030.mpls ".

When the recording controller 62 reads the path indicating the recording destination of the additional content, the recording controller 62 controls the drive 51 to supply the position to the position of the optical disc 41 represented by the read path. Record the content. The drive 51 records the additional content supplied from the recording controller 62 to the optical disc 41 in accordance with the instructions of the recording controller 62.

Since the optical disc 41 has previously recorded a certificate, a token, and AACS data which are used in common with other contents necessary for reproducing the additional content, the user records the optical disc 41 with the recording and reproducing apparatus 11. And the additional content recorded on the optical disc 41 can be viewed.

In step S143, the acquisition unit 63 updates the status information of the additional content recorded on the optical disc 41 from "downloaded" to "disc recorded".

In step S144, the recording controller 62 deletes the additional content recorded on the optical disc 41 from the recorder 53, and the additional content recording process ends. That is, the recorder 53 deletes the additional content recorded in accordance with the instruction of the recording controller 62.

In the above-described manner, the recording and reproducing apparatus 11 records the additional content downloaded and recorded in the recorder 53 on the optical disk 41.

As described above, by recording the additional content recorded in the recorder 53 on the optical disc 41 and deleting the recorded additional content from the recorder 53, the recording area of the recorder 53 is prevented from running out. can do. In addition, the user can watch the recorded additional content and the recorded content recorded in advance by the optical disc 41 alone.

As described above, according to the recording and reproducing apparatus 11, it is possible to download additional contents purchased in advance by the user and to record them on the optical disc 41. As a form of use of the recordable optical disc 41 of the additional content purchased in advance, for example, a form shown in FIGS. 16 to 18 is considered.

In the mode of use shown in FIGS. 16 to 18, the first episode (motion picture data) is recorded in advance in the contents of the series drama consisting of the first episode to the third episode, and the second episode and the third episode are recorded in advance. It is assumed that an optical disk 41 capable of recording additional video data is purchased. In other words, the first episode becomes recorded content, and the second episode and third episode become additional content.

In the form of use shown in FIG. 16, the user purchases the optical disc 41 in which the first episode is recorded. When the second episode is released and uploaded to the service server 13, the recording / reproducing apparatus 11 acquires the second episode from the service server 13.

When the user operates the button 162, an operation signal corresponding to the user's operation is supplied from the input unit 52 to the controller 54.

In step S172, the recording and reproducing apparatus 11 accesses a purchase page of the related content. That is, the controller 54 reads out the URL stored in the item "link" in the update information displayed in the display field 161-1 among the update information recorded in the recorder 53. For example, the URL in the tag "link" of the entry of the portion of K14 in FIG. 7 is read.

Then, the controller 54 transmits the URL read out to the communication unit 55 to the service server 13, and transmits data for displaying the purchase page (web page) recorded at the position indicated by the URL. It requests to the service server 13.

When the URL of the purchase page is transmitted from the recording / reproducing apparatus 11, in step S201, the service server 13 receives the transmitted URL. Then, the service server 13 transmits the data of the purchase page recorded at the position indicated by the received URL to the recording / playback apparatus 11 via the communication network 15.

The communication unit 55 receives the data of the purchase page transmitted from the service server 13 and supplies it to the controller 54. In step S173, the controller 54 supplies the data supplied from the communication unit 55 to the display device 14 and causes the display device 14 to display the purchase page.

When the purchase page is displayed on the display device 14, the user inputs a user ID for identifying the user registered in the service server 13 in advance, and designates the content to be purchased to instruct the purchase of the content. do. Then, an operation signal indicative of the input user ID and the designated content is supplied from the input unit 52 to the controller 54.

In step S174, the controller 54 requests the payment of the purchase of the content from the service server 13. That is, the controller 54 acquires a product ID which specifies the specified content from the image data for displaying the purchase page, based on the information indicating the content supplied from the input unit 52. The controller 54 supplies a purchase request signal to the communication unit 55 including a user ID and a product ID to request payment, and the communication unit 55 purchases a request signal from the controller 54. Is sent to the service server 13.

Then, in step S202, the service server 13 receives a purchase request signal transmitted from the recording / reproducing apparatus 11 and makes a payment. That is, the service server 13 confirms that the user who has requested the purchase of the product is a regular registered user based on the user ID included in the received purchase request signal, and is included in the purchase request signal. Payment is made for the content specified by the product ID. At this time, the service server 13 records necessary information such as a user ID and a product ID.

When the payment for the purchase of the content specified by the requested product ID is completed, the service server 13 transmits a notification of the completion of the payment to the recording / playback apparatus 11. Then, the communication unit 55 of the recording and reproducing apparatus 11 receives the notification transmitted from the service server 13 and supplies it to the controller 54, and the controller 54 receives the notification supplied from the communication unit 55. The display device 14 is supplied and displayed. As a result, the display device 14 displays a notification that the settlement of the purchase of the content has been completed.

Then, when the user performs an operation on the input unit 52 and instructs download of the purchased content, an operation signal instructing the download of the content is supplied from the input unit 52 to the controller 54.

In step S175, the acquisition unit 63 of the controller 54 requests the service server 13 to transmit the content in accordance with the operation signal from the input unit 52. FIG. That is, the acquisition unit 63 supplies the communication unit 55 with a transmission request signal for requesting transmission of the content including the user ID input at the time of purchase of the content and the specified product ID. The communication unit 55 then transmits a transmission request signal from the controller 54 to the service server 13.

Here, the content purchased by the user is, for example, the moving picture data of the sixth to tenth episodes of the series drama, and at this point, only the sixth episode is released and can be viewed. We shall not be able to watch until episode 10.

When the transmission request signal is transmitted from the recording / reproducing apparatus 11 to the service server 13, in step S203, the service server 13 receives the transmitted transmission request signal and records the requested content in the recording / reproducing apparatus 11. Send to That is, the service server 13 specifies the content to be transmitted to the recording / playback apparatus 11 from the user ID and product ID included in the received transmission request signal.

For example, the service server 13 transmits the information indicating the content purchased by the user to the user specified by the user ID and the information indicating the content provided to the user, that is, the recording and reproducing apparatus 11. Information indicating the content is recorded, and the content to be transmitted is specified from these information and the user ID and the product ID. For example, when the contents of the sixth to tenth episodes of the series drama are purchased by the user, the contents of the sixth episode are specified as the content to be transmitted.

When the content to be transmitted is specified, the service server 13 transmits the specified content to the recording / playback apparatus 11. In more detail, the service server 13 also transmits the certificate and AACS data common to all the contents purchased by the user to the recording / reproducing apparatus 11 together with the contents. Thus, for example, the content of the sixth episode, the certificates common to the sixth to tenth episodes, and AACS data commonly used in the sixth to tenth episodes are transmitted to the recording and reproducing apparatus 11. .

Here, the content to be transmitted is encrypted by an encryption key corresponding to a decryption key included in the AACS data, and the content information, feed URL, access frequency information, and access authentication information are added as meta information. .

When the content is transmitted from the service server 13 to the recording / playback apparatus 11, in step S176, the communication unit 55 of the recording / playback apparatus 11 is the content transmitted from the service server 13, more specifically. Receive content, credentials, and AACS data. The communication unit 55 supplies the received content to the controller 54. As a result, other content related to the content is obtained from the service server 13 indicated by the update information based on the update information of the predetermined content.

The acquisition part 63 of the controller 54 supplies the recorder 53 with the content, certificate, and AACS data supplied from the communication part 55, and records it. In addition, the controller 54 causes the display device 14 to display a message prompting the insertion of the optical disk. The user who saw the message inserts a so-called blank disk into the recording / reproducing apparatus 11 which is different from the optical disk 41 in which nothing is recorded, that is, the optical disk 41 in which the first to fifth episodes are recorded. do.

When an optical disc 41 with nothing recorded therein is inserted into the recording / reproducing apparatus 11, the controller 54 instructs the drive 51 to read the media ID from the optical disc 41. The media ID is identification information unique to the optical disc 41 and has been recorded in advance in the optical disc 41. The recording controller 62 of the controller 54 instructs the drive 51 to generate a predetermined random number and to write the random number to the optical disc 41 as random data.

In step S177, the drive 51 reads the media ID from the optical disk 41 and supplies it to the controller 54 according to the instruction of the controller 54, and optically outputs the random data supplied from the controller 54. The data is recorded at a predetermined position of the disc 41.

In step S178, the acquisition unit 63 of the controller 54 requests acquisition of a token required for reproduction of the content purchased by the user. That is, the acquisition unit 63 supplies the communication unit 55 with an acquisition request signal including a user ID, a product ID, a media ID read from the optical disc 41, and generated random data. The communication unit 55 then transmits an acquisition request signal from the acquisition unit 63 to the service server 13.

Then, in step S204, the service server 13 receives the acquisition request signal transmitted from the recording / reproducing apparatus 11, and transmits a token to the recording / reproducing apparatus 11 in response to a request of the recording / reproducing apparatus 11. .

In other words, the service server 13 generates a Token required when playing back the content purchased by the user, using the media ID and the random data included in the received acquisition request signal and predetermined data recorded in advance. . At this time, a token related to the content specified by the user ID and the product ID is generated. Then, the service server 13 transmits the generated token to the recording / playback apparatus 11, and the content selling process ends. Here, the generated token is commonly used, for example, when the contents of the sixth through tenth contents are played back.

When the Token is transmitted from the service server 13 to the recording / playback apparatus 11, in step S179, the communication unit 55 of the recording / playback apparatus 11 receives the Token transmitted from the service server 13. The communication unit 55 supplies the received token to the controller 54, and the acquisition unit 63 of the controller 54 supplies the token from the communication unit 55 to the recorder 53 and records it.

Then, the recording controller 62 reads the received, recorded content, certificate, AACS data, and token from the recorder 53 and supplies it to the drive 51, and supplies the optical disk such as the content to the drive 51 ( Write to 41) is instructed.

In step S180, the drive 51 writes the contents, the certificate, the AACS data, and the token supplied from the recording controller 62 to the inserted optical disc 41 in accordance with the instructions of the recording controller 62.

If the content is recorded on the optical disc 41, in step S181, the recording controller 62 deletes the content, certificate, AACS data, and Token recorded on the optical disc 41 from the recorder 53, and purchases the content. The process ends.

As a result, the optical disc 41 includes contents of the sixth episode among the sixth to tenth contents purchased by the user, certificates required for reproduction of the sixth to tenth episodes, AACS data, and tokens. This is in a recorded state. Therefore, when the seventh to tenth episodes are released in sequence, the user can download these contents as additional contents to the recording / reproducing apparatus 11 for viewing, or write them to the optical disc 41. In such a case, the above-described reproduction processing, content update processing, additional content reproduction processing, and additional content recording processing are appropriately performed by the recording / reproducing apparatus 11.

As described above, the recording and reproducing apparatus 11 requests the service server 13 to pay for the purchase of new content according to the user's instruction, downloads the content, and records the content on the optical disc 41. .

As described above, by requesting the payment to download the content and recording the content on the optical disc 41, the user can obtain the optical disc 41 on which the purchased content is recorded by a simple operation. In addition, the user only checks the update information of the content viewed by the user, operates a button set in the list of update information, for example, the button 162 of FIG. 12, and inputs necessary information such as a user ID. You can easily purchase content related to your own content.

In the above description, when the payment for the purchase of the content is completed, the content corresponding to the recorded content is downloaded and recorded on the optical disc 41. However, the recording of the content onto the optical disc 41 does not have to be performed immediately after the payment. do. That is, for example, when the user instructs after payment, the content may be downloaded, and the content may be recorded on the optical disc 41.

After payment for the purchase of the content, the user can receive the optical disc 41 on which the content is recorded at a particular store. Alternatively, the user may purchase the optical disc 41 directly at the store without paying for the purchase.

In addition, in the above, when the recording / reproducing apparatus 11 acquires the update information from the update information distribution server 12, only the newly obtained update information is recorded among the acquired update information. Alternatively, the update information distribution server 12 may transmit only necessary update information to the recording / playback apparatus 11.

In such a case, the recording / reproducing apparatus 11 and the update information distribution server 12 perform the process shown in FIG. 20, for example. That is, FIG. 20 is a flowchart for describing content update processing, update information transmission processing, and content providing processing performed by the recording / playback apparatus 11, the update information distribution server 12, and the service server 13. .

In step S241, the acquisition unit 63 of the recording / playback apparatus 11 determines whether to obtain update information based on the access frequency information included in the meta information of the recorded content recorded in the recorder 53. Determine.

If it is determined in step S241 that no update information is obtained, the process returns to step S241 and the determination process is repeated until it is determined that the update information is obtained.

In contrast, when it is determined in step S241 that the update information is acquired, in step S242, the acquisition unit 63 requests the update information delivery server 12 to transmit the update information.

That is, the acquisition part 63 reads the feed URL and access authentication information contained in the meta information from the recorder 53. FIG. The acquisition unit 63 requests transmission of the update information by transmitting the read feed URL and access authentication information and the list of update information acquired so far to the update information distribution server 12 through the communication unit 55. do.

Here, in the list of update information acquired so far, for example, as shown in FIG. 21, the update information obtained last, more specifically, the item "id" and the item "updated" in the item "feed" of transmission information ID and update date and time, and ID and update date and time are stored in item "id" and item "updated" in item "entry" for each entry included in the transmission information.

In the example of FIG. 21, the part K61 of the list of update information contains the information stored in the item "id" and the item "updated" in the item "feed" of transmission information. That is, the part of K61 contains the information contained in the tag "id" and the tag "updated" of the part K11 of FIG.

In addition, each of the part of K62 and the part of K63 of FIG. 21 contains the information regarding the entry of transmission information. That is, the part of K62 contains the information contained in the tag "id" and the tag "updated" in K12 of FIG. 7, The part of K63 contains the tag "id" and the tag "updated in K13 of FIG. Information contained in the "

As described above, the list of update information transmitted to the update information distribution server 12 includes information for specifying the last received transmission information and information for specifying the received entry (update information). . Therefore, the update information distribution server 12 which received the list of update information can know which update information is recorded in the recording / reproducing apparatus 11 which requested the update information.

Returning to the description of the flowchart in FIG. 20, when the list of feed URLs, access authentication information, and update information is transmitted from the recording / reproducing apparatus 11 to the update information distribution server 12, and transmission of update information is requested, In step S271, the update information distribution server 12 generates update information.

That is, the update information distribution server 12 receives a list of feed URLs, access authentication information, and update information transmitted from the recording / reproducing apparatus 11, and the user uses the received access authentication information in advance. Authenticate whether or not it is a registered regular user. And if authentication is performed, the update information distribution server 12 will transmit information which contains all the update information except the update information represented by the list of received update information among the update information specified by the received feed URL. Create As a result, transmission information including only an entry of update information not yet acquired by the recording / reproducing apparatus 11 is generated.

In step S272, the update information delivery server 12 transmits the update information, more specifically, the generated transmission information to the recording and reproducing apparatus 11, and the update information transmission process ends.

In step S243, the communication unit 55 of the recording and reproducing apparatus 11 receives the update information transmitted from the update information distribution server 12, that is, the transmission information. The communication unit 55 then supplies the received update information to the acquisition unit 63 of the controller 54.

When update information (transmission information) is supplied from the communication unit 55, the acquisition unit 63 supplies the supplied update information to the recorder 53.

In step S244, the recorder 53 records the update information supplied from the acquisition unit 63. As a result, update information that has not been acquired so far is newly recorded in the recorder 53. Thereafter, the processing of step S245 to the processing of step S251 is performed, but since these processing are the same as each of the processing of step S46 of FIG. 5 to the processing of step S52, the description thereof is omitted.

In addition, although the process of step S301 and the process of step S302 are performed by the service server 13, since these processes are also the same as the process of step S71 of FIG. 5, and the process of step S72, the description is abbreviate | omitted.

In the above-described manner, the recording / reproducing apparatus 11 transmits a list of acquired update information and requests transmission of update information, thereby newly acquiring and recording only update information that has not been acquired yet. As described above, by transmitting the list of update information, it is possible to prevent duplication of acquiring already obtained update information.

In addition, although it demonstrated that the list of update information is transmitted at the time of acquisition of update information, the update information distribution server 12 acquires which update information is acquired for every recording reproduction apparatus 11, without transmitting a list of update information. May be managed.

In such a case, for example, the reproducing process and the registration process shown in the flowchart of FIG. 22 are performed by the recording / reproducing apparatus 11 and the update information distribution server 12, and the user, and more specifically, the recording / reproducing apparatus 11. ) Is registered. Since the process of step S341 and the process of step S342 are the same as the process of step S11 and the process of step S12 of FIG. 4, the description thereof is omitted.

That is, when the optical disc 41 which has not been reproduced so far is inserted into the recording and reproducing apparatus 11, the recording and reproducing apparatus 11 reads the meta information from the inserted optical disc 41 and records the recorder 53. To record.

If the meta information is recorded, in step S343, the controller 54 requests registration of the recording / playback apparatus 11 (user) to the update information distribution server 12 via the communication unit 55. That is, the controller 54 includes information for specifying the contents of the optical disc 41, information for specifying the recording / reproducing apparatus 11, specifically, org ID and disc ID included in the meta information, The device ID of the recording and reproducing apparatus 11 is supplied to the communication unit 55. The communication unit 55 then transmits the org ID, disc ID, and device ID supplied from the controller 54 to the update information distribution server 12, and requests registration of the recording / reproducing device 11.

Here, the device ID is information previously recorded in the recording / reproducing apparatus 11, and is information for identifying the recording / reproducing apparatus 11. The update information distribution server 12, i.e., the access destination, which is a request for registration of the recording / reproducing apparatus 11 may be a URL included in the meta information, and the recorder 53 or the optical disc 41 are previously described. It is good also as a URL recorded.

When the org ID, disc ID, and device ID are transmitted from the recording / reproducing device 11 to the update information delivery server 12, in step S361, the update information delivery server 12 transmits the org ID, disc ID, And the device ID, and the recording and reproducing apparatus 11 is registered.

That is, the update information distribution server 12 records the received org ID, disc ID, and device ID. In addition, whenever the update information distribution server 12 transmits the update information to the recording / playback apparatus 11 specified by the device ID thereafter, the update information delivery server 12 records and reproduces the content specified by the org ID and disc ID. The list of update information sent to the device 11 is recorded. When the update information delivery server 12 is requested to transmit the update information, the update information delivery server 12 generates the update information to be transmitted to the recording / playback apparatus 11 with reference to the list of recorded update information.

In the above-described manner, in the update information distribution server 12, when the recording / playback apparatus 11 is registered, the update information distribution server 12 sends a notification to the recording / playback apparatus 11 that the registration has been completed. And the registration process ends. In the update information distribution server 12, the content may be specified from information obtained by simply arranging the org ID and the disc ID. Alternatively, a value unique to each content may be calculated by calculation using the org ID and the disc ID. The content can be specified.

In addition, the communication unit 55 of the recording and reproducing apparatus 11 receives the notification of the completion of the registration sent from the update information distribution server 12 and supplies it to the controller 54. The controller 54 supplies the notification supplied from the communication unit 55 to the display device 14, and causes the display device 14 to display a notification indicating that registration has been completed.

In addition, the controller 54 records the registration flag for the purpose of user registration (device registration of the recording / reproducing apparatus 11), that is, the registration flag that is set, in the recorder 53 in association with the meta information. This registration flag is a flag indicating whether or not to perform the process of acquiring update information. When the registration flag is reset, the registration flag is a timing for acquiring the update information based on the access frequency information. Not done.

When the registration flag is recorded in the recorder 53, the process of step S344 and the process of step S345 are then performed, and the reproduction process ends, but these processes are the same as the process of step S13 and step S14 of FIG. Therefore, the description is omitted.

In the above-described manner, the recording / reproducing apparatus 11 transmits the org ID, disc ID, and device ID to the update information distribution server 12, requests registration of the recording / reproducing apparatus 11, and distributes the update information. The server 12 registers the recording and reproducing apparatus 11 in response to a request of the recording and reproducing apparatus 11.

By registering the recording / reproducing apparatus 11 in advance in the above-described manner, the recording / reproducing apparatus 11 can simply acquire only necessary update information.

In the update information distribution server 12, when the recording / playback apparatus 11 is registered, in order to acquire update information of the content of the optical disc 41, the content update process and update described with reference to the flowchart of FIG. Processing similar to the information transmission processing and the content providing processing is performed.

However, if the registration flag recorded in association with the meta information of the content for which the update information is to be obtained is reset, the content update process is not performed.

In the process of step S242, the communication unit 55 transmits the org ID, the disc ID, and the device ID to the update information distribution server 12, and requests transmission of the update information.

In addition, upon receiving the transmitted org ID, disc ID, and device ID, the update information distribution server 12 authenticates whether it is the registered recording / reproducing device 11 based on the device ID, and then org ID, disc. Based on the ID, the device ID, and the list of recorded update information, transmission information composed of update information to be transmitted to the recording / playback apparatus 11 is generated. That is, transmission information containing only update information not yet transmitted is generated and transmitted to the recording / reproducing apparatus 11.

In the above-described manner, when the recording and reproducing apparatus 11 is registered by the update information distributing server 12, the update information distributing server 12 indicates which update information has been transmitted to each recording and reproducing apparatus 11. I can figure it out. The update information includes, for example, information for notifying release of new content related to content owned by the user. In order to acquire and display the update information from the update information delivery server 12 without requiring the user's instruction, the recording and reproducing apparatus 11 can regard a part of the update information presented to the user as an advertisement. Therefore, depending on the results of the transmission of the update information from the update information distribution server 12, the manufacturer of the recording / playback apparatus 11 may obtain the advertisement publication fee from the provider of the content.

In addition, the user may deregister the recording and reproducing apparatus 11 in the update information distribution server 12 so that update information may not be obtained. In such a case, for example, the processing shown in the flowchart of FIG. 23 is performed.

FIG. 23 is a flowchart for describing deregistration request processing and deregistration processing performed by the recording / reproducing apparatus 11 and the update information distribution server 12.

When the user operates the input unit 52 and instructs the display of the menu screen while the optical disc 41 is not inserted into the recording / reproducing apparatus 11, the user inputs the controller 54 from the input unit 52 to the controller 54. The operation signal according to the operation is supplied.

When the operation signal is supplied to the controller 54, in step S391, the controller 54 displays the menu screen of FIG. 11 based on the meta information and update information recorded in the recorder 53, for example. 14).

After the menu screen is displayed, if the user further performs an operation on the input unit 52 to instruct the release of the recording / reproducing apparatus 11 regarding the contents of the specific optical disc 41, the controller from the input unit 52 An operation signal corresponding to the user's operation is supplied to 54.

In step S392, the controller 54 requests the update information distribution server 12 to release the registration of the recording and reproducing apparatus 11 for the content designated by the user through the communication unit 55. That is, the controller 54 stores information for specifying the content designated by the recorder 53 and the recording / reproducing apparatus 11, specifically, the org ID and disc ID included in the meta information of the designated content, and the device ID. It reads and supplies it to the communication part 55. The communication unit 55 transmits the org ID, disc ID, and device ID supplied from the controller 54 to the update information distribution server 12, and requests the release of the recording / reproducing apparatus 11 to be released.

Then, in step S411, the update information distribution server 12 receives the org ID, disc ID, and device ID transmitted from the recording / reproducing apparatus 11, and records them according to the request of the recording / reproducing apparatus 11. The registration of the playback device 11 is released. That is, for the recording / playback apparatus 11 specified by the received device ID, information about the list of update information for the content specified by the org ID and the disc ID is deleted, and the recording / playback apparatus 11 is registered. Release it. Therefore, after this, even if transmission of the update information is requested for the content specified by the org ID and the disc ID, the update information is not transmitted.

When the update information delivery server 12 releases the registration of the recording / reproducing apparatus 11, it transmits a notification to the recording / reproducing apparatus 11 that the release of registration has been completed, and the registration release processing ends.

In addition, the communication unit 55 of the recording and reproducing apparatus 11 receives a notification that the release of registration transmitted from the update information distribution server 12 is completed and supplies it to the controller 54. The controller 54 supplies the notification supplied from the communication unit 55 to the display device 14, and causes the display device 14 to display a notification that the release of registration is completed.

In step S393, the controller 54 resets the registration flag recorded in the recorder 53, and the deregistration request processing ends. When the registration flag is reset, update information of the content corresponding to the registration flag is not obtained.

In the above-described manner, the recording / reproducing apparatus 11 requests the update information distribution server 12 to release the registration of the recording / reproducing apparatus 11, and resets the registration flag. By requesting the release of registration, it is possible to prevent the update information from being unnecessarily acquired.
