Abstract

PROBLEM TO BE SOLVED: To provide an information processor and a network copy system in which digital content can be copied to a recording medium via a network with good operability and without wasting the recording medium because of an error during copying.SOLUTION: An information processor receives digital content from a transmission side information processor via a network, and includes a medium recorder with a recording medium set in an insertable/removable manner, a storage unit and a record control module. The record control module stores the digital content uploaded from the transmission side information processor in the storage unit, and writes the digital content stored in the storage unit onto the recording medium of the medium recorder after uploading or during uploading.

Description

  Embodiments described herein relate generally to an information processing apparatus and a network copy system.

  For example, when content that has been digitally recorded on a device having a recording function (referred to as digital content) is copied to another device or dubbing such as moving is performed, if UPnP or DLNA technology is used, the content is stored in the device on the transmission side. The digital content can be written to a recording medium (for example, a BD disc) set in a content recording / playback apparatus (this is called a media drive) mounted on or connected to a receiving device via a network.

  When performing such dubbing of digital contents, the user usually operates the remote controller of the transmitting device to upload to the receiving device, that is, the hard disk device (hereinafter referred to as “HDD”) of the receiving device. ) Once, and then the remote controller of the receiving device is operated, and the contents stored in the HDD are written to the BD disc from the HDD, followed by a two-step dubbing operation procedure.

  In the above dubbing procedure, the user operates the transmitting device to upload the recorded program to the receiving device, and then operates the receiving device again to write to the recording medium. There is a problem that it is necessary to change the device to be operated in the middle of the operation, which increases the time and effort of the operation.

  This problem is caused by connecting the sending device and the receiving device that support the HD Recording Link standard one-to-one with the same standard cable from the sending device to the receiving device as well as the HDD. Other than that, dubbing can be performed by designating media, which can be eliminated.

  By the way, when the transmission side device and the reception side device are connected via a general-purpose communication network such as a LAN and content is dubbed from the transmission side device to the reception side device, the communication speed is lowered or the LAN cable is disconnected. Data transfer may be interrupted due to network problems (external factors), and errors may occur in the dubbing operation during content transfer.

JP 2006-18871 A

  However, if an error occurs when the content transmitted from the transmitting device is directly written to the recording medium by the receiving device, the recording medium is not normal.

  For example, in a recording medium such as a BD-R disc that can be written only once, not only data that caused an error during dubbing can be read but also data cannot be written to the disc again, so the recording medium itself is wasted. turn into.

  The problem to be solved by the present invention is to provide an information processing apparatus and a network copy capable of copying digital content to a recording medium via a network with good operability and without wasting the recording medium due to an error during copying. To provide a system.

  An information processing apparatus according to an embodiment is connected to a transmission-side information processing apparatus in which digital content is stored via a network, and receives the digital content from the transmission-side information processing apparatus via the network A storage device that can be designated as a copy destination of the digital content, a media recording device in which a recording medium that can be designated as the copy destination of the digital content is detachably set, and a recording control module.

  Hereinafter, embodiments will be described in detail with reference to the drawings. FIG. 1 is a diagram illustrating a configuration of a network copy system according to an embodiment.

  As shown in FIG. 1, the network copy system of this embodiment is a first device on the transmission side that transmits digital content (hereinafter referred to as “content”) such as a recorded program title, that is, a first information processing apparatus. A television device 1 (hereinafter referred to as “TV1”), and a BD-equipped hard disk recorder 2 (hereinafter referred to as “recorder 2”) as a second information processing device as a second device on the receiving side that receives content. Are connected via a network 3 such as a LAN.

  This network copy system copies content from a TV 1 to a recording medium set so as to be detachable in a removable media drive 19 as a media recording device mounted on or connected to the recorder 2 via the network 3. Note that dubbing means copying the original content to another recording medium. Also, deleting the original content after copying is called “move”. That is, moving is included in the copy.

  The TV 1 and the recorder 2 exchange requests (responses) and responses (responses) with a UPnP (Universal Plug and Play) function in accordance with, for example, the guidelines of DLNA (Digital Living Network Alliance), and between devices in the network 3 Exchange information and share resources. Regarding the content dubbing function, either the TV 1 or the recorder 2 may be the transmission side or the reception side, and the dubbing function may have the same configuration. In this example, the configuration of the recorder 2 is shown as an example in FIG. Show. Some TVs 1 do not have a removable media drive 19. In the case of the TV 1, the display module 14 is an essential element on a relatively large screen, but the recorder 2 uses the screen of the TV 1 as a display module without a small screen or screen.

  As shown in FIG. 2, the recorder 2 (TV1) includes a digital tuner 11, a decryption module 12, a decryption module 13, a display module 14, a content management information extraction module 15, a content management information management module 16, an encryption module 17, It includes a digital interface 18 (hereinafter referred to as “digital IF”), a removable media drive 19, a content management information creation module 20, a hard disk drive 21, a memory 22, an operation unit 26, a control module 27, and the like.

  The digital tuner 11 receives digital broadcasting such as terrestrial digital broadcasting, BS broadcasting, and CS broadcasting. The decryption module 12 decrypts the digital broadcast code received by the digital tuner 11 and sends the program data of the reception channel to the decryption module 13. Note that program data is sent to the encryption module 17 during recording.

  The decryption module 13 demodulates the content of the program from the program data sent from the decryption module 12 and outputs it to the display module 14. The display module 14 displays the content of the program received from the decryption module 13 on the screen.

  In the case of the receiving side (recorder 2), the content management information extraction module 15 extracts content management information from the encrypted data (program content data) received from the network 3. In the case of the transmission side (TV1), the container (content management information) included in the response is extracted.

  The content management information management module 16 stores the content management information extracted by the content management information extraction module 15 (which content is stored in what state and where) in the storage area of the hard disk drive 21 or the memory 22. to manage.

  The encryption module 17 encrypts the content to be stored and stores (records) it in a predetermined storage area (content storage folder) of the removable media drive 19 or the hard disk drive 21.

  The digital IF 18 is a communication unit that transmits data to the network 3 or receives data from the network 3, for example.

  The removable media drive 19 is a media recording / playback device built in (installed) or externally connected to the main body of the recorder 2, such as a Blu-ray multi-drive (hereinafter referred to as “BD drive”), and is a BD, BD-R. In addition to BD-RE and the like, data can be recorded (written) / reproduced (read) on removable recording media (hereinafter referred to as “removable media”) of various standards and types such as DVD and CD.

  The removable media is set so as to be detachable from the tray of the removable media drive 19. In other words, the removable media drive 19 is a media recording device in which a recording medium that can be designated as a content copy destination is detachably set.

  The content management information creation module 20 creates content management information (metadata) for managing the received content.

  The hard disk drive 21 is a storage device with a built-in hard disk or an integrated recording medium that can be designated as a content copy destination. In addition, the storage device may be a flash memory such as an SSD and an SD card.

  In the case of the recorder 2 on the receiving side, if the copy destination is the removable media drive 19, a temporary storage area (such as a temp folder) different from the storage area when the hard disk drive 21 is designated as a normal dubbing destination is generated. The contents and metadata uploaded from the TV 1 are held in the temp folder. The metadata is data indicating the content of the encrypted recorded program content (actual data).

  The operation unit 26 is, for example, a remote controller or a key operation unit, and is a graphic user interface screen (GUI screen) displayed on the display module 14 (dubbing destination device designation screen in FIG. 6, drive designation screen in FIG. 7, drive designation screen in FIG. A selection operation (instruction) on a recording list screen, a dubbing confirmation screen in FIG.

  For example, the operation unit 26 on the transmission side (TV1) selects (instructs), for example, either HDD or BD / DVD from the drive designation screen 50 (see FIG. 7) on which the type of copy destination, storage capacity, and the like are displayed. Is possible. In the case of the receiving side (recorder 2), the dubbing operation from the TV 1 does not require the operation on the recorder 2 side.

  The control module 27 includes a transmission control module 31, a notification module 32, a screen output module 33, an upload module 34, a media information module 35, a recording control module 36, and the like.

The transmission control module 31 controls data transmission (transmission and reception) to the network 3.
After uploading the content, the notification module 32 of the TV 1 on the transmission side displays the copy completion information received from the recorder 2 on the reception side on the display module 14.

  The screen output module 33 on the TV 1 side reads the copy destination information acquired from the recorder 2 at the time of dubbing from the memory 22 and displays various GUI screens (FIGS. 6 to 9 and the like) on the display module 14.

  The upload module 34 on the TV 1 side uploads the program title selected by the user to a desired copy destination (such as the hard disk drive 21 or the removable media drive 19 on the recorder 2 side). That is, the upload module 34 uploads content from the copy destination information displayed on the display module 14 to the designated copy destination.

  When the removable media drive 19 is connected, the media information module 35 on the recorder 2 side can record data by referring to the removable media drive information preset in the memory 22 by the plug and play function. The type (standard and type) and capacity of a removable medium is read, and media information is created from these information.

  Then, the media information module 35 transmits the created media information to the network 3 (connected to the TV 1) through the digital IF 18. In addition, the type (standard and type) and capacity of removable media that can be recorded may be read from the removable media drive 19 in response to a search request from the TV 1.

  That is, the media information module 35 on the recorder 2 side collects at least the storage capacity of the removable medium set in the removable media drive 19 that can be specified as the copy destination and the storage capacity of the hard disk drive 21, and transmits it as the copy destination information. It functions as an information collection module that transmits to the TV 1 that is the information processing apparatus.

  The media information module 35 of the TV 1 searches the network 3 for a copy destination (such as the hard disk drive 21 or the removable media drive 19 of the recorder 2) that can be dubbed by exchanging commands to the network 3. The retrieved copy destination information (media information including the type and capacity of the removable medium on which data can be recorded) is acquired from the retrieved device and stored in the memory 22.

  When the hard disk drive 21 is designated as a content copy destination on the TV 1 side, the recording control module 36 of the recorder 2 stores (saves) the content uploaded from the TV 1 in a predetermined storage destination such as a Video folder. )

  The recording control module 36 of the recorder 2 also stores a temp folder (BD dubbing temporary folder) in the hard disk drive 21 when a removable medium of the removable media drive 19 such as a BD disc is designated as a content copy destination on the TV 1 side. And the content uploaded from the TV 1 is stored in the created temp folder.

The recording control module 36 of the recorder 2 writes the contents of the temp folder to the BD disc set in the removable media drive 19 when the uploading of the contents is completed, and then erases the contents in the temp folder and the temp folder.
In other words, the recording control module 36 erases the content from the hard disk drive 21 after the content has been written to the recording medium.

  At the time of dubbing, the recording control module 36 determines the end of content upload based on the presence / absence of information indicating the last content written in the content metadata. In the description of the create object request 25 in FIG. 10, the information indicating the last content indicates that the content is the last content when the line 25a is set to last = "1", and last = " If it is “0”, it indicates that the content is not the last content.

  The recording control module 36 of the recorder 2 transmits copy completion information to the TV 1 when the writing of the content to the BD disc is normally completed.

  The memory 22 of the TV 1 stores information on the copy destination acquired from the recorder 2 (information on the removable media drive 19 (media information) and information on the hard disk drive 21).

  As for the media information, when the removable media set is, for example, a BD-R disc, the writable capacity is one of two types of 25 Gbytes and 50 Gbytes, and when the removable media is a BD-RE disc, the writable capacities are 25 Gbytes and 50 Gbytes. One of the two types.

  This media information is fixed data recorded in advance in a non-volatile storage area such as the hard disk drive 21 when the recorder 2 is manufactured, and a dubbing operation of the operation unit 26 by a user for dubbing with the recorder 2 is performed. Sometimes, the control module 27 reads the data from the nonvolatile storage area of the hard disk drive 21 into the memory 22.

  As another method, for example, data is embedded as media information in dubbing software, or the user sets the media information by some means and saves it in a nonvolatile storage area. Alternatively, the media information stored in the non-volatile storage area may be read into the memory 22 by the control module 27 at the time of startup or the like.

  Further, when the dubbing function is activated, the control module 27 may read the media information read from the removable medium by the removable media drive 19 onto the memory 22.

  The operation of this network copy system will be described below with reference to FIGS.

  The TV 1 and the recorder 2 are connected via the network 3, and the TV 1 detects a receiving device (in this case, the recorder 2) by the UPnP device discovery function.

  When the receiving device is detected, the TV 1 acquires drive information as copy destination information that the recorder 2 can receive.

  The drive information includes a drive name, a reception availability status, a reception destination ID, a total capacity, a free capacity, the number of receivable titles, and the like. When there are a plurality of receiving destination drives as in this example, information on each drive is acquired. The drive information is acquired by a SOAP action or the like. At this time, for example, a drive information acquisition request 23 as shown in FIG. 4 is issued from the TV 1 (step S101 in FIG. 3).

  The drive information acquisition request 23 includes information such as the content length, the content type, and the fact that this request is a soap action and an upload destination request.

  In response to the drive information acquisition request 23, the recorder 2 returns a drive information acquisition response 24 (step S102).

  As shown in FIG. 5, the drive information acquisition response 24 includes information on a device capable of dubbing content mounted on or connected to the recorder 2. In the case of this example, information on devices capable of dubbing content includes, for example, information on the hard disk drive 21 and information on the removable media drive 19.

  Information on the hard disk drive 21 includes destID = "hdd" as the destination ID, totalCapacity = 536870912000 bytes as drive capacity information, availableCapacity = 229421737000 bytes as available capacity information of the drive, and the like.

  The information of the removable media drive 19 includes destination ID = destID = “bd”, drive capacity information, totalCapacity = 26843545600 bytes, drive usable capacity information, availableCapacity = 26842173200 bytes, and the like.

  The control module 27 of the TV 1 receives the drive information acquisition response 24 sent back from the recorder 2 and stores it in the memory 22 as received drive information (copy destination information) (step S103).

  That is, the control module 27 of the TV 1 holds the information on the copy destination acquired from the recorder 2 in the memory 22 by exchanging commands with the recorder 2.

  Here, when the user operates an item by a procedure of “dubbing” → “dubbing destination list display” from the menu screen of the TV 1 by remote control operation (step S 104), the screen output module 33 of the TV 1 is stored in the memory 22. The dubbing destination device designation screen 40 (see FIG. 6), which is a list of detected devices, is displayed using the information of the copy destination that is present (step S105).

  As shown in FIG. 6, “Dad HDD” 41, “LAN DISK1” 42, “LAN DISK2” 43, “LAN DISK3” 44, “recorder” 45, etc. are displayed on the dubbing destination device designation screen 40. The

  When the user selects a dubbing destination device such as “Recorder” 45 to be dubbed from the list (step S106), the screen output module 33 reads the drive information of the recorder 2 that is the designated device from the memory 22. Then, a drive designation screen 50 showing a list of receiving drives is displayed (step S107).

  As shown in FIG. 7, the drive designation screen 50 displays a plurality of drive names “HDD” 51, “BD / DVD” 52, and the like as the drive names acquired by the drive information acquisition operation described above.

  When the user selects and operates the “BD / DVD” 52 on the drive designation screen 50 to designate a reception drive (step S108), the media information module 35 of the TV 1 has no change in the device configuration on the reception side. In order to confirm this, a drive information acquisition request 23 is issued (step S109), and when the drive information acquisition response 24 is returned from the recorder 2 in response to this request (step S110), it is included in the drive information acquisition response 24. From the information, it is determined whether or not the designated receiving drive is receivable (step S111). If destID = "bd" exists in the drive information acquisition response 24, it is determined that reception is possible.

  If it is determined that reception is possible, the screen output module 33 displays the recording list screen 60 (FIG. 8) (step S112).

  As shown in FIG. 8, on the recording list screen 60, a list of contents already recorded (saved) on the hard disk drive 21 in the TV 1 is displayed with the title name 61, and a check box 62 is placed at the head position of the title name. Is provided. Titles whose check boxes 62 are checked are to be dubbed. A message prompting selection (check) by a remote control operation is displayed at the bottom of the recording list screen 60.

  Here, the user selects one or more titles that he / she wants to dubb and checks the check box. At this time, the following various determinations are made based on the drive information acquired in advance.

  For example, the TV 1 can determine whether or not dubbing is possible depending on whether or not reception is possible, whether titles to be dubbed can be included in the disc due to free space, and how many titles can be dubbed depending on the number of receivable titles.

  When the user selects a title desired to be dubbed and then operates the determination button on the remote controller, the screen output module 33 displays a dubbing confirmation screen 70 (FIG. 9).

  As shown in FIG. 9, on the dubbing confirmation screen 70, a display 71 indicating dubbing from my HDD to a BD / DVD, a message 72 indicating that a plurality of program titles are dubbed, and a dubbing execution screen are executed. The button “Yes” 73 and the button “No” 74 for stopping the dubbing are displayed.

  When the user selects “Yes” 73 on the dubbing confirmation screen 70 using the remote controller, the upload module 34 checks the drive information on the receiving side (steps S114 to S116), and then starts uploading the selected content.

  In checking the drive information on the receiving side, a drive information acquisition request is made before starting dubbing (step S114), a response to the request is received (step S115), and reception is checked (step S116).

  After checking whether or not reception is possible, dubbing over the network from the TV 1 to the recorder 2 is executed if reception is possible.

  In this case, the upload module 34 generates a create object request for the first content, transmits the metadata of the content (step S117), then transmits the data of the recorded title that is the actual content by HTTP POST. DTCP-IP finalize processing is performed. If there are multiple titles, this process is repeated for the number of titles (step S118).

  In the recorder 2, the recording control module 36 determines whether to save the content (title) sent from the TV 1 on the BD disc or on the hard disk drive 21. This determination is performed using information included in the create object request 25 (metadata) sent from the TV 1.

  As shown in FIG. 10, the ID of the destination drive is specified in the create object request 25, and the storage device is identified by this ID. In this example, since destID = "bd" is specified in the row 25a, the BD disc is the storage location.

  On the recorder 2 side, since all the titles selected by the user are received by the HDD and then automatically transferred to dubbing from the HDD to the BD, it is necessary to know which title is the last title selected by the user. This determination also uses the metadata of the create object request 25.

  In the example shown in FIG. 10, last = "1" is specified for the last title, and last = "0" is specified for other than the last title. In the example of FIG. 10, it can be determined that the title is the last.

  Since the total dubbing title number (totalCount) and the current dubbing number (serialNo.) Are also added to the create object request 25, the last title can be identified from these pieces of information.

  The title dubbed by designating the BD disc of the recorder 2 from the TV 1 is temporarily stored in a specific folder (temp folder) created in the HDD (step S119). The title stored in the temp folder is a target for dubbing to the BD disc.

  After the title determined to be the last title is stored in the hard disk drive 21, the recording control module 36 of the recorder 2 initializes the disk for the uninitialized disk (step S120), and then the temp folder Are sequentially written on the BD disc (step S121).

  When the writing of all titles in the temp folder is completed, the recording control module 36 of the recorder 2 notifies the TV 1 of the completion of dubbing to the BD disc (step S122).

  In the TV 1 that has received the dubbing completion notification, the notification module 32 outputs a message indicating that all titles specifying the BD disc of the recorder 2 have been dubbed to the BD disc to the display module 14 and displays them on the screen (step). S123). By this screen display, the user can confirm the completion of dubbing to the BD disc that has been performed in the background in the recorder 2.

  In the recorder 2, when the dubbing end power off setting information (LC_POWEROFF) is added to the create object request 25, the recording control module 36 notifies the dubbing end and then turns off the recorder 2 power. (OFF) (step S124).

  As described above, according to this embodiment, when the content of the program recorded on the TV 1 is dubbed to the recorder 2 via the network, the BD disc of the recorder 2 is designated from the TV 1 and the dubbing is performed. Then, a dubbing waiting folder (temp folder) is generated in the hard disk drive 21, and the content is uploaded to the folder, that is, once saved, and then written on the BD disc after the upload is completed. Thereby, the user can dubb on the BD disc without operating the recorder 2. In addition, after a dubbing start, when a transfer error occurs due to a network failure or the like, writing to the BD disc is not performed directly, so the probability of wasting the BD disc can be reduced.

In other words, according to the embodiment, there is provided an information processing apparatus and a network copy system capable of copying digital content to a recording medium via a network with good operability and without wasting the recording medium due to an error during copying. Can be provided.
