Description

  The present disclosure relates to a content recording method, a recording apparatus, and a recording system for recording content.

  In recent years, with the spread of smartphones, tablet computers, and the like, an environment has been established in which videos can be easily viewed using mobile devices even outside the home. In particular, video on a video distribution site can be viewed using mobile communication standards such as LTE (Long Term Evolution), and streaming viewing of video in a mobile environment has become widespread. However, streaming viewing outside the home has two problems as described below.

  First, as a first issue, even if it is free broadcast content, if the broadcast content IP retransmission service is not provided free of charge, the user can view the excellent broadcast content outside the home using mobile communication. There is a problem that it is not common to do.

  Also, as the second issue, the monthly usage upper limit for packet flat-rate contracts for mobile communications is limited to about 7 GB, and if it exceeds 7 GB, you will be charged beyond the flat rate, so full HD etc. There is a problem that it is not reasonable in view of communication charges to view high-quality moving images for a long time.

  In order to solve the above two problems, a broadcast recorder such as an optical disk recorder has a function of transferring recorded content to an SD memory card, USB media, a smartphone, a tablet computer, or a portable game machine. Yes.

  For example, Patent Document 1 discloses a configuration in which content is moved from a digital video recorder to a mobile phone using a memory card. A digital video recorder is usually a stationary type, and is connected to a television at home to reproduce a recorded broadcast program or distributed content. Broadcast programs or distribution contents recorded on a digital video recorder cannot be viewed outside the home as they are. For this reason, use cases in which a broadcast program or distribution content is recorded and viewed on a portable playback device or recording medium are becoming widespread.

  In particular, in Japan, when a broadcast content is recorded, a so-called dubbing 10 operation rule that allows nine copies and one move for each recorded content was started in 2008. This makes it easier to record the broadcast content and take it outside the home for viewing. In view of viewing on a portable playback device, in addition to viewing on a dedicated playback terminal, viewing on a smartphone or tablet computer that has been rapidly spreading in recent years has been demanded. Even with small smartphones, products with HD resolution screens have appeared, and it has become possible to take HD broadcast contents of digital broadcasts outside the home and view them.

(Knowledge that became the basis of this disclosure)
In recent years, recording media that have obtained approval for recording contents broadcast in HD quality as they are by using the latest encryption technology have appeared. By using such a recording medium, it is possible to reproduce the content recorded on the recording medium with an in-vehicle AV device or with a television set at a business trip destination or a travel destination hotel. A mechanism for recording content recorded by a recorder on a portable playback device or recording medium is also known.

  However, this mechanism is a mechanism that merely mechanically synchronizes between the recorder and the playback device or recording medium based on information such as genre, creation date, or update date, and does not necessarily require a broadcast program or user desired by the user. This is not a mechanism for recording the distribution content on a playback device or a recording medium.

  Also, a channel automatic recording system recorder (recording server) that records all broadcast content for a specific channel or all channels at a predetermined time and automatically deletes old content from the recorded content. Is spreading.

  However, conventionally, a method for recording content recorded by such an automatic channel recording method on a portable terminal has not been studied.

  In addition, the conventional method of recording content on a mobile terminal has a problem in usability, and even if a recorder has a function of recording content on the mobile terminal, it is not used much.

  The present disclosure has been made in order to solve these problems, and provides a content recording method, a recording apparatus, and a recording system that can improve user convenience.

  A content recording method according to an aspect of the present disclosure is a content recording method in a recording apparatus that records content on a recording medium, and the content broadcasted in a channel and a time zone specified by a user is recorded on the channel of the recording medium. A channel automatic recording control step for automatically recording in the automatic recording area; and when detecting that communication with a mobile device that is communicably connected to the recording apparatus is detected, the channel automatic recording area in the past A deletion step for causing the mobile device to delete the content copied or moved to the mobile device, and the content recorded in the channel automatic recording area when the communication with the mobile device is detected is detected. Content transfer step of copying or moving to the mobile device.

  When it is detected that communication with the mobile device is possible, content that has been copied or moved from the channel automatic recording area to the mobile device in the past will be deleted from the mobile device, so it is unnecessary to record it on the mobile device. Content can be automatically deleted, and user convenience can be improved.

  Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Note that the following embodiment is an example in which the present disclosure is embodied, and does not limit the technical scope of the present disclosure.

  The present disclosure easily realizes an environment in which video content is taken out of the house and viewed by linking a recording device (recording server) having an automatic channel recording function and a mobile server.

  The recording server includes a recording medium. The recording medium includes a channel automatic recording area for automatically recording content of a program broadcast in a channel and time zone specified by a user, an individual recording area for recording content of a program individually reserved by the user, A personal data recording area for storing a photograph or a moving picture taken with a smartphone or a digital still camera (DSC) or the like, music purchased and ripped by a user and transferred.

  When a mobile server is connected to the recording server and synchronization becomes possible, a part of the contents of the channel automatic recording area (corresponding to dubbing 10) in the recording server is automatically sent to the mobile server by the method specified by the user in advance. Synchronously (transfer). For example, the recording server may include one of the latest one week of content, the latest two weeks of news and weather forecasts, a drama watched at least once within a week, and a movie broadcast during the latest month. Automatically transfer one or more to the mobile server. The recording server automatically transfers as much content as the recording capacity of the mobile server allows to the mobile server.

  Pay broadcast content (dubbing 1 content) in the individual recording area and the channel automatic recording area is transferred by the user individually specifying. The dubbing 1 content is content that can be copied only once. With regard to the personal data recording area, when content is newly added to the mobile server, the newly added content is automatically copied from the mobile server to the personal data recording area.

  The mobile server includes a channel automatic recording content transfer area for storing contents of a channel automatic recording area in the recording server, an individual recording content transfer area for storing contents of an individual recording area in the recording server, and personal data in the recording server. The personal data temporary recording area for storing the contents of the recording area is individually managed.

  The recording server automatically deletes the existing content stored in the channel automatic recording content transfer area of the mobile server by a method designated in advance by the user. Also, the recording server automatically transfers new content that can be stored in the channel automatic recording content transfer area of the mobile server from the channel automatic recording area to the channel automatic recording content transfer area by a method designated in advance by the user. As a result, the user does not need to manually delete the past contents in the mobile server each time the contents of the recording server and the contents of the mobile server are synchronized, and also needs to worry about the free capacity of the mobile server. In addition, the latest broadcast content desired by the user can be stored in the mobile server.

  The mobile server uses DLNA (Digital Living Network Alliance) function, etc., to easily stream video content to mobile devices (for example, tablet computers, smartphones or in-vehicle TVs) or DLNA compatible televisions. By playing the transferred video content, it is possible to view the broadcast content outside the home.

  Furthermore, by transferring personal content such as still images or moving images taken with a DSC, video camera, smartphone, or the like to the mobile server, the user can take a picture without worrying about the recording capacity of the device. Normally, when transferring personal contents to the mobile server, the user needs to check the recording capacity in the mobile server. However, for example, based on a method specified in advance by the user such as deleting the oldest content in order, the content in the channel automatic recording content transfer area is deleted to create a free area in the mobile server, thereby reducing the capacity of the mobile server. You can transfer personal content without worrying.

  When personal content such as photos is recorded on the mobile server, the recording server automatically acquires the personal content from the mobile server when performing synchronization processing with the mobile server. At this time, if there is no free area in the personal data recording area of the recording server, the channel automatic recording area of the recording server is automatically reduced to secure the free area of the personal data recording area. In that case, the user can select whether to reduce the recording period from 30th to 29th or to increase the compression rate of some or all of the content without reducing the recording period, for example, as the area is secured. Is specified in advance.

(Embodiment 1)
[Description of recording system]
FIG. 1 is a diagram showing a configuration of a recording system in the present embodiment.

  The recording system includes a recording server 100 and a mobile server 200.

  The recording server 100 includes a channel automatic recording area 111, an individual recording area 112, a system control unit 121, a recording control unit 122, a synchronization control unit 124, and a playback control unit 126.

  The channel automatic recording area 111 records the content of a program broadcast in a channel and time zone designated by the user. The individual recording area 112 records the contents of programs individually reserved by the user. For example, a recording medium such as a magnetic disk used for a hard disk drive includes a channel automatic recording area 111 and an individual recording area 112.

  The system control unit 121 controls the entire recording server 100. The recording control unit 122 automatically records the broadcast content 350 by designating a channel group, a time zone, a compression rate, and the like that the user wants to record. The recording control unit 122 automatically records the content of the program broadcast in the channel and time zone specified by the user in the channel automatic recording area 111 of the recording medium. Further, the recording control unit 122 reserves recording of programs individually designated by the user, and records the contents of the reserved programs in the individual recording area 112 of the recording medium. Further, the recording control unit 122 deletes the content designated by the user from at least one content recorded in the individual recording area 112.

  The synchronization control unit 124 communicates with the mobile server 200 and synchronizes the recorded content with the mobile server 200. The synchronization control unit 124 detects that communication with the mobile server 200 communicatively connected to the recording server 100 is possible, and copies or moves the content recorded in the channel automatic recording area 111 to the mobile server 200. . Note that the recording server 100 may be communicably connected to one mobile server 200, or may be communicably connected to a plurality of mobile servers 200. Further, when the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the mobile server 200 deletes content that has been copied or moved from the channel automatic recording area 111 to the mobile server 200 in the past. .

  Further, when the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the content recorded from the channel automatic recording area 111 to the mobile server 200 among the contents recorded from the channel automatic recording area 111 to the mobile server The mobile server 200 is caused to delete content that has exceeded the transfer period indicating the content transfer period.

  Furthermore, when the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the number of days that have elapsed since the previous detection that communication with the mobile server 200 was possible is the number of days specified by the user. If the number is less, the content recorded in the channel automatic recording area 111 after being detected may be copied or moved to the mobile server 200 regardless of the designated number of days.

  The playback control unit 126 plays back the recorded content stored in the channel automatic recording area 111 and the individual recording area 112. The user can view the reproduced content on the television 400 or the like.

  The broadcast content 350 includes free broadcast content (such as dubbing 10 content) that can be viewed for free and pay broadcast content (such as dubbing 1 content) that can be viewed for a fee. The recording system targets only free broadcast content or both free broadcast content and pay broadcast content. The dubbing 10 content is content that allows nine copies and one move. The channel automatic recording area 111 automatically records a broadcast program (broadcast content) according to the recording capacity, and automatically deletes old programs. This eliminates the need for the user to designate and reserve a program to be recorded, and to delete the recorded content recorded in the automatic channel recording area 111 in order to secure a free recording capacity for recording. It becomes unnecessary.

  The playback control unit 126 has a program table type interface that displays a recording target channel for selecting the recorded content in order to view the recorded content in the channel automatic recording area 111. In addition, the playback control unit 126 displays individual recording contents in order to view the recording contents in the individual recording area 112 and selects the recording contents, or performs search processing for the recording contents in the individual recording area 112 And an interface for selecting recorded content.

  The mobile server 200 includes a channel automatic video recording content transfer area 211, an individual video recording content transfer area 212, a system control unit 221, a synchronization control unit 224, and a playback control unit 226.

  The channel automatic recording content transfer area 211 stores the recording contents stored in the channel automatic recording area 111 in the recording server 100. The individual recording content transfer area 212 stores the recording contents stored in the individual recording area 112 in the recording server 100. The recording capacities of the channel automatic recording content transfer area 211 and the individual recording content transfer area 212 are not fixed, and the channel automatic recording content transfer area 211 depends on the recording capacity of the recording contents stored in the individual recording content transfer area 212. Recording capacity can be increased or decreased.

  The system control unit 221 controls the entire mobile server 200.

  The synchronization control unit 224 communicates with the recording server 100 and synchronizes the recorded content with the recording server 100. The synchronization control unit 224 records the recorded content transferred from the recording server 100 in the channel automatic recording content transfer area 211 or the individual recorded content transfer area 212.

  The synchronization control unit 224 records the recorded content stored in the channel automatic recording area 111 of the recording server 100 in the channel automatic recording content transfer area 211 among the recorded contents transferred from the recording server 100. Further, the synchronization control unit 224 records the recorded content stored in the individual recording area 112 of the recording server 100 in the individual recorded content transfer area 212 among the recorded contents transferred from the recording server 100.

  Further, based on an instruction from the recording server 100, the synchronization control unit 224 deletes content that has been copied or moved from the channel automatic recording area 111 in the past from the channel automatic recording content transfer area 211.

  When the mobile server 200 is close to the recording server 100 and is connected to the recording server 100 by wireless communication such as Wi-Fi communication, it is possible to synchronize the contents recorded with each other. Alternatively, the mobile server 200 can synchronize content recorded with each other by being connected to the recording server 100 by wired communication such as a USB cable.

  When the synchronization is enabled, a part of the free broadcast content (corresponding to dubbing 10) in the channel automatic recording area 111 in the recording server 100 according to the method specified by the user using the user interface of the recording server 100 in advance. Automatically transferred to the mobile server 200. Note that the recording server 100 may, for example, include the latest one week of content, the latest two weeks of news and weather forecasts, a drama that has been viewed at least once within two weeks, and a movie broadcast during the latest month. One or more designations are accepted. In addition, the recording server 100 accepts a designation to transfer content as much as the recording capacity of the mobile server 200 allows.

  When the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the synchronization control unit 124 copies or moves the content recorded in the channel automatic recording area 111 to the mobile server 200 based on the user's viewing history. The content to be selected may be selected, and the selected content may be copied or moved to the mobile server 200.

  The contents of the individual recording area 112 are transferred by being individually designated by the user. When the contents of the individual recording area 112 are transferred, the old contents in the channel automatic recording contents transfer area 211 in the mobile server 200 are automatically deleted, so that the user is not aware of the latest contents at all. Content can be transferred to the mobile server 200.

  The playback control unit 226 transmits the content recorded in the channel automatic video recording content transfer area 211 or the individual video recording content transfer area 212 to a display device communicably connected to the mobile server 200.

  By using the DLNA function or the like, the mobile server 200 can easily stream video content to the mobile device group (the portable information terminal 500 or the in-vehicle TV 600) or the DLNA compatible television 410, and can play back video on each device. To do. The portable information terminal 500 is, for example, a tablet computer or a smartphone.

  FIG. 2 is a diagram showing a flow of recorded content in the recording system of the present embodiment.

  The automatic recording filter 172 performs channel automatic recording processing on the broadcast content 350 in accordance with channel automatic recording setting conditions set by the user. Broadcast content 350 to be automatically recorded is stored as copyable recorded content (such as dubbing 10) 301 in the channel automatic recording area 111. In addition, the recording reservation unit 176 performs a recording process according to a recording reservation setting in which a user individually specifies a recording program. Broadcast content 350 to be reserved for recording is stored as copyable recorded content (such as dubbing 10) 302 in the individual recording area 112.

  The copyable recording content 301 in the channel automatic recording area 111 is automatically recorded sequentially in accordance with the setting of the automatic recording filter 172. Also, the old copyable recorded content 301 is automatically deleted. Accordingly, among the copyable recorded content 301, the recorded content that the user desires to store for a long period is moved from the channel automatic recording area 111 to the individual recording area 112 (movement process 181). As a result, the copyable recorded content 301 can be excluded from automatic deletion and managed as the copyable recorded content 302 in the individual recording area 112.

  In the playback control unit 126, the recorded content moved from the channel automatic recording area 111 to the individual recording area 112 is selected as the recorded content in the individual recording area 112, and the channel automatic recording area after the moving process 181 is performed. 111 may be selected as recorded content.

  The mobile device ID management unit 161 stores the device ID 261 of a mobile device such as the mobile server 200 managed by the recording server 100 or the portable recording medium ID in the mobile device, and the copyable recorded content 301 in the channel automatic recording area 111. Alternatively, the mobile device or the portable recording medium that transfers the copyable recording content 302 in the individual recording area 112 is managed.

  Data such as recorded content between the recording server 100 and the mobile server 200 by connecting the mobile server 200 to the recording server 100 wirelessly or by connecting the mobile server 200 and the recording server 100 via a wired network. The automatic transfer process 182 is performed when the synchronization process becomes possible. In the automatic transfer process 182, the copyable recorded content 301 in the channel automatic recording area 111 is automatically transferred to the channel automatic recording content transfer area 211 in the mobile server 200 according to the transfer conditions set by the user in the automatic transfer filter 174. . The recorded content switched to the management in the individual recording area 112 in the movement process 181 is excluded from the target of the automatic transfer process 182. However, when the user specifies that the recorded content moved by the movement process 181 is included in the automatic transfer process 182, it can be the target of the automatic transfer process 182.

  When synchronization processing becomes possible, transfer processing 183 is performed in addition to automatic transfer processing 182. In the transfer process 183, the copyable recorded content 302 in the individual recording area 112 is automatically transferred to the individual recorded content transfer area 212 in the mobile server 200 according to the conditions set by the user in the transfer reservation unit 178.

  The recorded content stored in the channel automatic video recording content transfer area 211 and the individual video recording content transfer area 212 in the mobile server 200 is wirelessly or wired (for example, a technology such as USB or Wi-Fi) by a communication function such as the DLNA standard. Is transmitted to the connected portable information terminal 500, and the recorded content can be reproduced and viewed on the portable information terminal 500.

  Communication of video content between the mobile server 200 and the portable information terminal 500 is not limited to streaming communication according to the DLNA standard or the like, and the mobile server 200 is connected from the portable information terminal 500 to an external recording device via a network. It can also be realized by handling.

  FIG. 3 is a diagram showing a first modification of the flow of recorded content in the recording system of the present embodiment.

  Whereas the recording server 100 shown in FIG. 2 targets only free broadcast content, in FIG. 3, the free broadcast content 300 (such as dubbing 10 content) and the pay broadcast content 310 (such as dubbing 1 content) are recorded. Shows the flow of content.

  The automatic recording filter 172 can set automatic recording reservation for the pay broadcast content 310 in addition to the free broadcast content 300. According to the setting of the automatic recording filter 172, the free broadcast content 300 is recorded in the channel automatic recording area 111 as the copyable recorded content 301. In addition, the pay broadcast content 310 is recorded in the automatic channel recording area 111 as the move-only recording content 311.

  In addition to the free broadcast content 300, the pay broadcast content 310 can also be set with respect to the setting of the recording reservation unit 176 that stores the result of individually specifying the recorded program by the user. By performing a recording process according to the setting of the recording reservation unit 176, the free broadcast content 300 is recorded in the individual recording area 112 as a copyable recorded content (such as dubbing 10) 302. In addition, the pay broadcast content 310 is recorded in the individual recording area 112 as the move-only recording content 312.

  Data such as recorded content between the recording server 100 and the mobile server 200 by connecting the mobile server 200 to the recording server 100 wirelessly or by connecting the mobile server 200 and the recording server 100 via a wired network. The automatic transfer process 182 is performed when the synchronization process becomes possible. In the automatic transfer processing 182, the copyable recorded content 301 in the channel automatic recording area 111 is transferred to the channel automatic recording content transfer area 211 in the mobile server 200 according to the transfer conditions set by the user in the automatic transfer filter 174.

  However, the move-only recorded content 311 in the channel automatic recording area 111 can be transferred to the mobile server 200 only once. In addition, when the move-only recorded content 311 is transferred, it cannot be viewed because it is deleted from the recording server 100. For this reason, if the move-only recorded content 311 is a target for automatic transfer, there is a possibility that the user automatically performs an unexpected operation.

  For this reason, unless the user explicitly instructs transfer, the move-only recorded content 311 is not transferred to the mobile server 200 by the automatic transfer processing 182. In order to transfer the move-only recording content 311 in the channel automatic recording area 111 to the mobile server 200, the move-only recording content 311 is moved from the channel automatic recording area 111 to the individual recording area 112 in accordance with a user instruction (movement processing). 181), and managed as move-only recording content 312.

  When synchronization processing becomes possible, transfer processing 183 is performed in addition to automatic transfer processing 182. In the transfer process 183, the copyable recording content 302 and the move-only recording content 312 in the individual recording area 112 are automatically transferred to the individual recording content transfer area 212 in the mobile server 200 according to the conditions set by the user in the transfer reservation unit 178. To do.

  The recording medium 210 of the mobile server 200 shown in FIG. 3 may be configured with a portable recording medium. At this time, the portable recording medium records a media ID for identifying the portable recording medium in the recording server 100. When the mobile server 200 has this configuration, the mobile device ID management unit 161 in the recording server 100 manages the media ID instead of the device ID 290. Therefore, when a plurality of portable recording media are used in one mobile server 200, the recording server 100 can manage one mobile server 200 as a plurality of mobile servers 200.

  The recording medium 210 of the mobile server 200 shown in FIG. 3 may be composed of a built-in recording medium and a portable recording medium. For example, the built-in recording medium includes a channel automatic recording content transfer area 211, and the portable recording medium includes an individual recording content transfer area 212.

  When the mobile server 200 has this configuration, the mobile device ID management unit 161 in the recording server 100 manages the combination of the device ID 261 and the media ID. Therefore, when a plurality of portable recording media are used in one mobile server 200, the recording server 100 can manage one mobile server 200 as a plurality of mobile servers 200.

  The recording medium 210 of the mobile server 200 includes a built-in recording medium and a portable recording medium. The built-in recording medium includes an individual recording content transfer area 212, and the portable recording medium is a channel automatic recording content. The transfer area 211 may be included.

  4 and 5 are diagrams showing an example of a mobile device ID management table for managing mobile devices and recording media. FIG. 4 is a diagram showing an example of a mobile device ID management table that manages the mobile device or recording medium, whether or not it supports channel automatic transfer, and the capacity of the channel automatic recording content transfer area in association with each other. FIG. 5 is a diagram showing an example of a mobile device ID management table for managing a combination of a mobile device and a recording medium, whether channel automatic transfer is supported, and a channel automatic recording content transfer area capacity in association with each other. It is. The mobile device ID management table is recorded in the mobile device ID management unit 161.

  In the table shown in FIG. 4, it is specified for each mobile server or portable media whether or not it is a target for automatic channel transfer during synchronization processing. When it is a channel automatic transfer target, the capacity of the channel automatic recording content transfer area is managed. For this reason, the automatic transfer filter 174 can manage the automatic transfer processing 182 to the mobile server 200 to be managed by the recording server 100 using the information in the mobile device ID management table.

  Further, in the table shown in FIG. 5, for each combination of the mobile server and the portable media, it is specified whether or not it is a target for automatic channel transfer at the time of synchronization processing. When it is a channel automatic transfer target, the capacity of the channel automatic recording content transfer area is managed.

  The mobile server 200 shown in FIG. 3 cannot specify a media ID item.

  When the recording medium 210 of the mobile server 200 is composed of a portable recording medium, since a plurality of devices can use the portable recording medium, it is meaningless to specify the item of device ID. .

  On the other hand, when the recording medium 210 of the mobile server 200 is composed of a built-in type recording medium and a portable type recording medium, since it is managed by a combination of a device ID and a media ID, both items of the device ID and the media ID are stored. Requires a valid ID to be specified.

  FIG. 6 is a diagram showing another example of a mobile device ID management table for managing mobile devices and recording media.

  In the table shown in FIG. 6, in addition to the table in FIG. 5, an item for specifying the presence / absence of automatic transfer processing of the recorded content stored in the individual recording area 112 is added. For this reason, the automatic transfer filter 174 can manage the automatic transfer processing 182 and the transfer processing 183 to the mobile server 200 to be managed by the recording server 100 using the information in the mobile device ID management table.

  FIG. 7 is a diagram showing a basic configuration of the recording server 100 in the present embodiment.

  In the recording server 100, the input / output control unit 123 that receives a signal from a remote controller 450, which is an example of an input device, transmits a user instruction to the system control unit 121 that controls the entire recording server 100. The system control unit 121 controls the recording control unit 122, the synchronization control unit 124, the reproduction control unit 126, the recording medium control unit 125, and the like.

  The recording control unit 122 includes a digital broadcast tuner 145, a transcoder 131, and a channel automatic recording management table 147.

  The digital broadcast tuner 145 receives a plurality of radio signals of the free broadcast content 300 and the pay broadcast content 310 based on the information stored in the channel automatic recording management table 147 and converts them into video signal groups. The transcoder 131 converts the received video signal into recorded content at a compression rate designated for each channel, and stores the converted recorded content in the channel automatic recording area 111.

  Also, when the user makes a recording reservation for an individual program, based on the information, the digital broadcast tuner 145 receives the radio signal of the free broadcast content 300 or the pay broadcast content 310 and converts it into a video signal. The transcoder 131 converts the received video signal into recorded content at a compression rate designated for each reserved program, and stores the converted recorded content in the individual recording area 112.

  The playback control unit 126 includes an AV decoder 133 and an HDMI (registered trademark) communication control unit 143. The recording medium control unit 125 extracts the recorded content in the channel automatic recording area 111 or the individual recording area 112 and sends it to the AV decoder 133. The AV decoder 133 converts the recorded content into a baseband video signal, and sends the converted video signal to the HDMI communication control unit 143. The HDMI communication control unit 143 transfers the video signal to a video display device such as the television 400. Thereby, the user can view the recorded content.

  The synchronization control unit 124 controls the Wi-Fi communication control unit 141 and the USB communication control unit 142 to communicate with the mobile server 200 and synchronize the recorded content recorded by the recording server 100 and the mobile server 200. I do. The synchronization control unit 124 selects the recorded content stored in the automatic channel recording area 111 based on the information in the automatic transfer management table 165 for each device ID when synchronization with the mobile server 200 becomes possible. Then, the selected recorded content is transferred to the mobile server 200 and recorded in the channel automatic recorded content transfer area 211 of the mobile server 200.

  If there is recorded content to be transferred to the individual recording area 112 and the recorded content is recorded in the DR mode, the transcoder 132 converts the recorded content at the specified compression rate before performing the transfer process. To do. The DR mode is a mode for recording a digital broadcast signal as it is. Since the compression processing using the transcoder 132 takes time, the recording content for transfer may be separately recorded in the individual recording area 112 before the transfer processing is performed.

  The recorded content in the channel automatic recording area 111 or the recorded content in the individual recording area 112 transferred from the recording server 100 to the mobile server 200 may be subjected to encryption processing. When the recorded content is encrypted, the recorded content needs to be encrypted and recorded in the mobile server 200 as well. In this case, in order to prevent the encrypted recorded content from being simply copied to another device and played back, the encrypted processing of the recorded content is performed by device-specific information such as the device ID of the recording server 100 or the mobile server. When the recording medium in 200 is a portable recording medium, it is bound using information unique to the recording medium such as the media ID of the portable recording medium. As the binding method, the recorded content itself is encrypted with a standard encryption process such as AES (Advanced Encryption Standard) with a device ID unique to the apparatus, and the recorded content itself is encrypted with a standard encryption process such as AES. In some cases, a key for reproducing the encrypted recorded content is encrypted with a device ID unique to the device.

  In the former case, the synchronization control unit 124 decrypts the encryption of the recording content to be transferred before performing the transfer process, and performs re-encryption processing using the device ID or media ID of the transfer destination mobile server 200 again. To transfer.

  In the latter case, the synchronization control unit 124 does not perform encryption conversion processing of the recorded content itself at the time of transfer, but after establishing a secure communication path (SAC) between the recording server 100 and the mobile server 200, the recording server The key for reproducing the recorded content encrypted with the unique information of 100 needs to be encrypted and transferred with the device ID or media ID of the mobile server 200.

  The method of encrypting the recorded content in the recording server 100 differs depending on the regulations of the country where the recording server 100 is used or the technology adopted. Also, the encryption processing of the mobile server 200 is different between a case where the recording medium is not composed of a portable recording medium and a case where the recording medium is composed of a portable recording medium. When the recording medium is composed of a portable recording medium, CPRM (Content Protection for Recordable Media), AACS (Advanced Access Content System), or NSM (Next Generation Security Memories Invite Memories Invite Memories Invite Memory Inventive Rules In accordance with this, the transfer processing of the recorded content is realized.

  The channel automatic recording management table 147 includes a recording channel designation item for designating a channel for channel automatic recording, a recording time zone designation item for designating a time zone to be automatically recorded within a day, and recording. It consists of an image quality designation item for designating the image quality and a recording period designation item for designating the number of days for automatic recording.

  Usually, the capacity of the channel automatic recording area 111 is designated, and if either one of the image quality and the recording period is designated, the other can be obtained by calculation.

  For example, the recording time zone, the image quality, and the recording period are specified collectively for all channels, not for each channel.

  At this time, when the capacity of the channel automatic recording area is 1 TB, the image quality is 15 times, and the recording period is not designated, the recording period is calculated based on the following equation.

Recording period = 1 TB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (6 [number of channels] * 17 [time])) * 15 [image quality]
= 1000 * 1000 / (18/8 * 60 * 60 * 6 * 17) * 15
= 18 days

  For example, when the capacity of the automatic channel recording area 111 is 1 TB, the recording period is specified as 3 weeks (21 days), and the image quality is not specified, the image quality is calculated based on the following equation. The

Image quality = (3 * 7) [3 weeks] * (18/8 Mbps [bandwidth] * 60 s * 60 s * (6 [number of channels] * 7 [time])) / 1 TB [capacity]
= 21 * (18 * 60 * 60 * 6 * 7/8) / (1000 * 1000)
= 7.14 times When the compression rate is specified only by an integer, the recorded content is compressed by 8 times.

  FIG. 8 is a diagram showing an example of the channel automatic recording management table 147.

  As shown in FIG. 8, the channel automatic recording management table 147 can specify the recording time zone and the image quality for each channel, and can meet the more detailed recording needs of the user. In FIG. 8, the start time of the recording time zone corresponding to the A broadcast station is specified at 7 o'clock, and the end time is specified at 24:00, and the B broadcast station, the C broadcast station, the D broadcast station, and the E broadcast station The start time of the corresponding recording time zone is specified at 18:00, the end time is specified at 25:00, the start time of the recording time zone corresponding to the F broadcasting station is specified at 23:00, and the end time is specified at 24:00 Yes.

  In this example, since the capacity of the channel automatic recording area is 1 TB and the recording period is specified as 2 weeks (14 days), the image quality is calculated based on the following equation.

Image quality = (2 * 7) [2 weeks] * (18/8 Mbps [bandwidth] * 60 s * 60 s * ((17 + 7 * 4 + 1) [time])) / 1 TB [capacity]
= 14 * (18 * 60 * 60 * (17 + 7 * 4 + 1) / 8) / (1000 * 1000)
= 5.2 times When the compression rate is specified only by an integer, the recorded content is compressed by 6 times.

  Further, when the recording time zone and the image quality can be specified for each channel in the channel automatic recording management table 147, it is possible to meet the more detailed recording needs of the user.

  For example, when the capacity of the channel automatic recording area is 1 TB, the recording time zone is specified as in FIG. 8 above, the image quality is 10 times, and the recording period is not specified, the recording period is expressed by the following formula: Is calculated based on

Recording period = 1 TB [capacity] / (18/8 Mbps [band] * 60 s * 60 s * (17 + 7 * 4 + 1) [time]) * 15 [image quality]
= 1000 * 1000 / (18/8 * 60 * 60 * 46) * 15
= 27 days

  FIG. 9 is a flowchart for explaining automatic transfer processing for automatically transferring the recorded content in the channel automatic recording area 111 to the channel automatic recording content transfer area 211 in the mobile server 200. FIG. 10 is a diagram illustrating an example of the automatic transfer management table 165 for each device ID.

  First, in step S1, the synchronization control unit 124 refers to the automatic transfer management table 165 for each device ID and selects the recorded content to be automatically transferred.

  As shown in FIG. 10, the automatic transfer management table 165 includes a recording channel designation item for designating a channel for automatic channel recording, and a recording time for designating a time zone for automatic recording within a day. Band designation item, image quality designation item for designating the recording quality, recording period designation item for designating the number of days for automatic recording, and automatic transfer for designating whether or not it is subject to automatic transfer for each channel It consists of target specification items.

  The recording channel designation item, the recording time zone designation item, the image quality designation item, and the recording period designation item are the same as the channel automatic recording management table 147. The recording time zone can be specified for each channel. Whether to automatically transfer the recorded content is designated for each channel designated by the recording channel designation. When the automatic transfer target designation item is set to “automatic”, a transferable period during which automatic transfer is possible is calculated. When the automatic transfer target designation item is set to “pause”, the recorded content of the channel is not transferred. The transferable period during which automatic transfer is possible can be calculated based on the recording capacity of the transfer destination.

  Further, since the pay broadcast channel recorded content (dubbing 1 content or move-only recorded content 311) cannot be automatically transferred, the automatic transfer target designation item becomes “impossible”.

  Further, in FIG. 10, the start time of the recording time zone corresponding to the A broadcast station is specified at 7 o'clock, and the end time is specified at 24 o'clock, and the B broadcast station, the C broadcast station, the D broadcast station, and the E broadcast station The start time of the corresponding recording time zone is specified at 18:00, the end time is specified at 25:00, the start time of the recording time zone corresponding to F broadcasting station is specified at 23:00, the end time is specified at 24:00, The start time of the recording time zone corresponding to the G broadcast station is specified at 0:00, and the end time is specified at 24:00.

  Here, when the capacity of the channel automatic video recording content transfer area 211 is 128 GB, the transferable period is calculated based on the following equation.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (17 + 7 * 2 + 1) [time]) * 10 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 32) * 10
= 4.8 days As described above, since the recorded contents for four days can be transferred, the synchronization control unit 124 selects the latest four days of recorded contents as the automatically transferred recording contents.

  Next, in step S <b> 2, the synchronization control unit 124 determines whether or not there is a recording content subject to automatic transfer that is not in the mobile server 200 in the recording server 100. Based on the selection result, the synchronization control unit 124 confirms whether or not the recording content to be automatically transferred in the channel automatic recording area 111 has already been transferred to the channel automatic recording content transfer area 211 in the mobile server 200. . If it is determined that there is no automatic transfer target recorded content in the mobile server 200 (NO in step S2), the process ends.

  On the other hand, when it is determined that there is recorded content that is not automatically transferred to the mobile server 200 (YES in step S2), in step S3, the synchronization control unit 124 has a free space for recording the recorded content in the mobile server 200. Determine whether or not. Here, when it is determined that there is a free area in the mobile server 200 for recording the recorded content (YES in step S3), in step S4, the synchronization control unit 124 transfers the recorded content to be automatically transferred. The synchronization control unit 224 of the mobile server 200 records the recorded content transferred by the recording server 100 in the channel automatic recorded content transfer area 211.

  On the other hand, when it is determined that there is no free space for recording the recorded content in the mobile server 200 (NO in step S3), in step S5, the synchronization control unit 124 sends the past to the mobile server 200 the recorded content to be automatically transferred. It is determined whether or not there is recorded content in. If it is determined that there is no recorded content recorded in the past in the mobile server 200 than the recorded content to be automatically transferred (NO in step S5), the process ends.

  On the other hand, when it is determined that there is recorded content recorded in the past in the mobile server 200 rather than the recorded content to be automatically transferred (YES in step S5), in step S6, the synchronization control unit 124 starts from the oldest recorded content. Instruct the mobile server to delete in order. The synchronization control unit 124 causes the mobile server 200 to delete the content with the oldest broadcast time among the content recorded on the mobile server 200.

  At this time, the synchronization control unit 124 instructs to delete the recorded content corresponding to the capacity capable of storing the recorded content to be automatically transferred. In addition, the synchronization control unit 124 may instruct to delete the recorded content in units of programs, or may instruct to delete the recorded content in units of time. When receiving the delete instruction from the recording server 100, the synchronization control unit 224 of the mobile server 200 deletes the recorded contents recorded in the channel automatic recorded content transfer area 211 in order from the oldest recorded contents. The synchronization control unit 124 instructs the mobile server to delete the oldest recorded content in order, and then proceeds to the process of step S4.

  Note that the automatic transfer management table 165 may specify the recording time zone, the image quality, and the recording period in a lump for all channels instead of for each channel. The automatic transfer target specification item specifies whether or not to transfer for each channel. The transferable period during which automatic transfer is possible is calculated according to the recording capacity of the transfer destination.

  For example, the recording capacity of the channel automatic recording content transfer area 211 of the mobile server 200 is 128 GB, the recording time zone of six channels is from 18:00 to 25:00, the image quality is 15 times, and the recording period is specified. If not, the transferable period is calculated based on the following formula.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (6 [number of channels] * 7 [time])) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 6 * 7) * 15
= 5.6 days As described above, since the recorded content for five days can be transferred, the synchronization control unit 124 selects the latest five days of recorded content as the recorded content to be automatically transferred.

  It is possible to set whether or not to automatically transfer the recorded content for each channel. When the automatic transfer target designation item is set to “pause”, the recorded content of the channel is not transferred. Among the recorded contents recorded in the channel automatic recording area 111, the recorded contents of the channel set not to be automatically transferred are excluded from the recorded contents to be automatically transferred. In this case, since the recorded content to be transferred decreases, the transferable period increases.

For example, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the recording time zone of six channels is from 18:00 to 25:00, the image quality is 15 times, the recording period is not specified, 2 When it is set not to automatically transfer the recorded content of one channel, the transferable period is calculated based on the following formula.
Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (4 [number of channels] * 7 [time])) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 4 * 7) * 15
= 8.4 Days As described above, since the recorded content for 8 days can be transferred, the synchronization control unit 124 selects the latest 8 days of recorded content as the automatically transferred recording content.

  Further, since the pay broadcast channel recorded content (dubbing 1 content or move-only recorded content 311) cannot be automatically transferred, the automatic transfer target designation item becomes “impossible”.

  For example, when the recording period is specified and the image quality is not specified, the transferable period needs to be calculated after calculating the image quality. However, the channel automatic recording area 111 and the channel automatic recording content transfer are simply transferred. It can be obtained by calculating a ratio with the area 211 and multiplying the calculated ratio by the recording period.

  For example, the capacity of the channel automatic recording area 111 is 1 TB, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the recording time zone of six channels is from 18:00 to 25:00, and the recording period is 4 weeks. (28 days) is specified, and when the image quality is not specified, the transferable period is calculated based on the following equation.

Transferable period = 28 [days] * (128 GB / 1 TB)
= 28/8 [Sun]
= 3.5 days Since the recorded content for three days can be transferred as described above, the synchronization control unit 124 selects the latest three days of recorded content as the automatically transferred recording content.

  Also, for example, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the recording time zone is specified in the same manner as in FIG. 10, the image quality is 10 times, the recording period is not specified, When F broadcast stations from 10 A broadcast stations are designated for automatic transfer, the transferable period is calculated based on the following equation.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (17 + 7 * 4 + 1) [time]) * 10 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 46) * 10
= 3.4 Days As described above, since the recorded content for three days can be transferred, the synchronization control unit 124 selects the latest three days of recorded content as the recorded content to be automatically transferred.

  In the above example, the transferable period is calculated by setting whether or not each channel is subject to automatic transfer. However, the present disclosure is not limited to this, and the transfer indicating the period for automatic transfer is performed. A period may be specified for each channel.

  FIG. 11 is a flowchart for explaining a first modified example of the automatic transfer process for automatically transferring the recorded content in the channel automatic recording area 111 to the channel automatic recording content transfer area 211 in the mobile server 200. FIG. 12 is a diagram showing another example of the automatic transfer management table 165 for each device ID.

  First, in step S <b> 11, the synchronization control unit 124 instructs to delete recorded content exceeding the transfer period specified in the automatic transfer management table 165 from the recorded content recorded in the mobile server 200.

  As shown in FIG. 12, the automatic transfer management table 165 includes a recording channel designation item for designating a channel for channel automatic recording, and a recording time for designating a time zone for automatic recording within a day. To specify the band specification item, the image quality specification item for specifying the recording image quality, the recording period specification item for specifying the number of days for automatic recording, whether or not it is an automatic transfer target, and the transfer period for each channel It consists of automatic transfer target and transfer period designation item.

  The recording channel designation item, the recording time zone designation item, the image quality designation item, and the recording period designation item are the same as the channel automatic recording management table 147. The recording time zone, the image quality, and the recording period are specified collectively for all channels, not for each channel. Whether to automatically transfer the recorded content is designated for each channel designated by the recording channel designation. The transfer period is also specified for each channel specified by the recording channel specification.

  In the automatic transfer management table 165 shown in FIG. 12, whether or not to automatically transfer the recorded content and the transfer period are represented by one item. When the automatic transfer target and transfer period designation items are set to “0 days”, the recorded content of the channel is not transferred. Further, when a specific period is set in the automatic transfer target designation item, for example, “5 days”, the recorded content corresponding to the transfer period is transferred. In FIG. 12, since the automatic transfer of the two channels is suspended, the overall capacity is reduced.

  Here, the required capacity of the channel automatic video recording content transfer area 211 can be calculated based on the designated content of the transfer period. In this case, the synchronization control unit 124 calculates the capacity of the channel automatic recording content transfer area 211 for each channel using the image quality (compression rate) of the recorded content, the recording time zone and the transfer period for each channel, and sets all the channels. The required capacity of the channel automatic video recording content transfer area 211 can be calculated. Accordingly, the required capacity of the channel automatic video recording content transfer area 211 is calculated based on the following equation.

Required capacity of channel automatic recording content transfer area = 18/8 Mbps [band] * 60 s * 60 s * (7 * (3 + 5) * 2) [time]) / 15 [image quality]
= (18/8 * 60 * 60 * (58) / 15
= 31.3GB
As described above, the capacity required for the channel automatic recording content transfer area 211 of the mobile server 200 is 32 GB.

  The process in step S12 in FIG. 11 is the same as the process in step S1 in FIG.

  Next, in step S <b> 13, the synchronization control unit 124 determines whether or not there is a recording content subject to automatic transfer within a transfer period that is not in the mobile server 200 in the recording server 100. Here, when it is determined that there is no recorded content subject to automatic transfer within the transfer period that does not exist in the mobile server 200 (NO in step S13), the process ends. On the other hand, when it is determined that there is a recording content subject to automatic transfer within the transfer period that does not exist in the mobile server 200 (YES in step S13), the process proceeds to step S14.

  Note that the processing from step S14 to step S17 in FIG. 11 is the same as the processing from step S3 to step S6 in FIG.

  The automatic transfer target and transfer period designation items shown in FIG. 12 are an automatic transfer target item for designating for each channel whether or not it is an automatic transfer target, and a transfer period designation item for designating the transfer period for each channel. It may be divided into

  For example, the recording time zone of six channels is from 18:00 to 25:00, the image quality is 15 times, the recording period is not specified, six channels are specified for automatic transfer, and two channels are transferred. When the period is 5 days and the transfer period of the four channels is 3 days, the required capacity of the channel automatic recording content transfer area 211 is calculated based on the following formula.

Required capacity of channel automatic recording content transfer area = 18/8 Mbps [band] * 60 s * 60 s * (7 * 4 * 3 + 7 * 2 * 5) [time]) / 15 [image quality]
= (18/8 * 60 * 60 * (154) / 15
= 83.2 GB
As described above, the capacity required for the channel automatic recording content transfer area 211 of the mobile server 200 is 84 GB.

  In the above example, whether or not to be subject to automatic transfer is set for each channel and the transfer period is set for each channel. However, the present disclosure is not limited to this, and the time for automatic transfer is set. A transfer time zone indicating a zone may be designated for each channel.

  FIG. 13 is a flowchart for explaining a second modified example of the automatic transfer process for automatically transferring the recorded content in the channel automatic recording area 111 to the channel automatic recording content transfer area 211 in the mobile server 200.

  The process in step S21 in FIG. 13 is the same as the process in step S1 in FIG.

  Next, in step S <b> 22, the synchronization control unit 124 determines whether or not there is a recording content subject to automatic transfer within a transfer time zone that is not in the mobile server 200 in the recording server 100.

  The automatic transfer management table 165 includes a recording channel designation item for designating a channel for channel automatic recording, a recording time zone designation item for designating a time zone for automatic recording within a day, and a recording image quality. The image quality specification item for specifying the image, the automatic transfer target specification item for specifying whether or not each channel is subject to automatic transfer, and the transfer time for specifying the automatic transfer time zone in the recording time zone It consists of a band designation item.

  The recording channel designation item, the recording time zone designation item, and the image quality designation item are the same as those in the channel automatic recording management table 147. The transfer time zone is specified for each channel, and the start time and end time are specified. Note that the transfer time period may be specified for all channels at once, not for each channel.

  When the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the synchronization control unit 124 converts the content of the channel and time zone designated by the user from the content recorded in the automatic channel recording area 111 to the mobile server. Copy or move to 200.

  For example, when the transfer time zone is designated, the transferable period can be calculated from the usable amount of the channel automatic video recording content transfer area 211. In this case, the transfer capacity required for one day for each channel can be calculated using the image quality (compression rate) of the recorded content and the transfer time zone for each channel. Therefore, the synchronization control unit 124 can calculate the transferable period (number of days) from the capacity of the channel automatic video recording content transfer area 211. Therefore, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the recording time zone of 6 channels is from 7 o'clock to 24 o'clock, the image quality is 15 times, and the transfer time zone of 6 channels is 20 o'clock. 23:00, the transferable period is calculated based on the following formula.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (3 * 6) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 18) * 15
= 13.2 days As described above, the recorded contents for 13 days can be automatically transferred to the mobile server 200.

  In addition, a transfer time zone may be designated for each channel. For example, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the recording time zone of six channels is from 7 o'clock to 24 o'clock, the image quality is 15 times, and the transfer time zone corresponding to the A broadcasting station is The start time is specified at 8 o'clock, the end time is specified at 8:30, and the start time of the transfer time zone corresponding to B broadcast station, C broadcast station, D broadcast station and E broadcast station is specified at 20:00 When the end time is specified at 23:00, the start time of the transfer time zone corresponding to the F broadcast station is specified at 23:00, and the end time is specified at 24:00, the transferable period is based on the following formula: Is calculated.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (0.5 + 3 * 4 + 1) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 13.5) * 15
= 17.6 days As described above, the recorded contents for 17 days can be automatically transferred to the mobile server 200.

  Further, the recording time zone, the image quality, and the transfer time zone may be designated for each channel. For example, the image quality corresponding to the A broadcast station, the B broadcast station, the C broadcast station, the D broadcast station, and the F broadcast station may be designated 15 times, and the image quality corresponding to the E broadcast station may be designated 10 times. In this case, the recorded content having the image quality (compression rate) of 10 times and the recorded content having the image quality of 15 times are mixed. Therefore, for example, the recording capacity of the automatic channel recording content transfer area 211 is 128 GB, the recording time zones of six channels are specified in the same way as in FIG. 10, the image quality of five channels is 15 times, The image quality is 10 times, the start time of the transfer time zone corresponding to the A broadcast station is specified at 8 o'clock, the end time is specified at 8:30, B broadcast station, C broadcast station, D broadcast station, The start time of the transfer time zone corresponding to the E broadcast station is specified at 20:00, the end time is specified at 23:00, the start time of the transfer time zone corresponding to the F broadcast station is specified at 23:00, and the end time is 24 When specified at times, the transferable period is calculated based on the following equation.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s) * (0.5 + 3 * 3 + 3 * 1.5 + 1) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 15) * 15
= 15.7 days As described above, the recorded contents for 15 days can be automatically transferred to the mobile server 200.

  Here, when it is determined that there is no recorded content subject to automatic transfer within the transfer time zone that does not exist in the mobile server 200 (NO in step S22), the process ends. On the other hand, when it is determined that there is a recording content subject to automatic transfer within the transfer time zone that does not exist in the mobile server 200 (YES in step S22), the process proceeds to step S23.

  Note that the processing in steps S23 to S26 in FIG. 13 is the same as the processing in steps S3 to S6 in FIG.

  In the above example, whether or not to be subject to automatic transfer is set for each channel, and a transfer time zone is set for each channel. However, the present disclosure is not limited to this, and automatic transfer is performed. In addition to the transfer time zone indicating the time zone, the genre of the recorded content to be transferred may be designated.

  FIG. 14 is a flowchart for explaining a third modified example of the automatic transfer processing for automatically transferring the recorded content in the channel automatic recording area 111 to the channel automatic recording content transfer area 211 in the mobile server 200.

  The process in step S31 in FIG. 14 is the same as the process in step S1 in FIG.

  Next, in step S <b> 32, the synchronization control unit 124 determines whether or not there is a recording content in the recording server 100 that is not in the mobile server 200 and is subject to automatic transfer of a genre.

  FIG. 15 is a diagram illustrating another example of the automatic transfer management table 165 for each device ID.

  The automatic transfer management table 165 includes a recording channel designation item for designating a channel for channel automatic recording, a recording time zone designation item for designating a time zone for automatic recording within a day, and a recording image quality. The image quality specification item for specifying the image, the automatic transfer target specification item for specifying whether or not each channel is subject to automatic transfer, and the transfer time for specifying the automatic transfer time zone in the recording time zone A band designation item and a genre designation item for designating the genre of the recorded content to be automatically transferred.

  The recording channel designation item, the recording time zone designation item, and the image quality designation item are the same as those in the channel automatic recording management table 147. The transfer time zone is specified for each channel, and the start time and end time are specified. The genre is specified for each channel, and for example, news, drama, variety, music, animation, sports, etc. are specified.

  As shown in FIG. 15, the recording capacity of the channel automatic video recording content transfer area 211 is 128 GB, the variety is 2.5 hours / day, the drama is 3 hours / day, and the news is 0. When the transfer time is 5 hours / day and the total transfer time is 6 hours, the transferable period is calculated based on the following equation.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (6) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 6) * 15
= 39.6 days As described above, the recorded contents for 39 days can be automatically transferred to the mobile server 200.

  If it is determined that there is no recorded content that is not included in the mobile server 200 and that is subject to automatic transfer of a genre (NO in step S32), the process ends. On the other hand, when it is determined that there is recorded content that is not in the mobile server 200 and is subject to automatic transfer of a genre (YES in step S32), the process proceeds to step S33.

  14 is the same as the process from step S3 to step S6 in FIG. 9 and will not be described.

  In FIG. 15, the transfer time zone and genre may be specified for all channels at once, not for each channel. The synchronization control unit 124 checks the genre information of each recorded content within the transfer time period, selects the recorded content to be automatically transferred, and calculates the total transfer capacity of the selected recorded content. The capacity can be calculated. Therefore, the synchronization control unit 124 can calculate the transferable period (number of days) from the capacity of the channel automatic video recording content transfer area 211. Therefore, the recording capacity of the channel automatic video recording content transfer area 211 is 128 GB, the image quality is 15 times, news is 5 hours / day, drama is 6 hours / day, and animation is 1 hour / day in the transfer time zone. Yes, when the total transfer time is 12 hours, the transferable period is calculated based on the following equation.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (12) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 12) * 15
= 19.8 days As described above, the recorded contents for 19 days can be automatically transferred to the mobile server 200.

  In addition, it may be set whether to automatically transfer the recorded content for each channel. When the automatic transfer target designation item is set to “pause”, the recorded content of the channel is not transferred.

  For example, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the image quality is 15 times, and it is set not to automatically transfer to two channels, and the news is 3 hours / day in the transfer time zone. When the drama is 4 hours / day, the animation is 1 hour / day, and the total transfer time is 8 hours, the transferable period is calculated based on the following formula.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (8) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 12) * 15
= 29.7 days As described above, recorded contents for 29 days can be automatically transferred to the mobile server 200.

  In FIG. 15, the transfer time zone may be specified for all channels at once, not for each channel, and the genre may be specified for each channel. In addition to specifying whether or not to automatically transfer for each channel, it is possible to specify both the transfer time zone of the recorded content and the genre for each channel. In this case, the synchronization control unit 124 selects the recorded content to be automatically transferred by checking the genre information of the recorded content for each channel within the transfer time period, and calculates the sum of the capacities of the selected recorded content. Thus, the necessary transfer capacity can be calculated. Therefore, the synchronization control unit 124 can calculate the transferable period (number of days) from the recording capacity of the channel automatic video recording content transfer area 211. Therefore, when the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the image quality is 15 times, and the average recording target time of 6 channels in the transfer time zone is 2 hours / day, the transferable period is It is calculated based on the following formula.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (12) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 12) * 15
= 19.8 days As described above, the recorded contents for 19 days can be automatically transferred to the mobile server 200.

  Also, for example, the recording capacity of the channel automatic video recording content transfer area 211 is 128 GB, the image quality is 15 times, the start time of the transfer time zone corresponding to the A broadcast station is specified at 8 o'clock, and the end time is 8:30 The start time of the transfer time zone corresponding to the B broadcast station, the C broadcast station, the D broadcast station and the E broadcast station is specified at 20:00, the end time is specified at 23:00, and the F broadcast station The start time of the transfer time zone corresponding to is specified at 23:00, the end time is specified at 24:00, the genre corresponding to the A broadcast station is specified as news and drama, and the genre corresponding to the B broadcast station is specified as drama. The genre corresponding to the C broadcasting station is designated as music, the genre corresponding to the D broadcasting station is designated as variety, the genre corresponding to the E broadcasting station is designated as drama, and corresponds to the F broadcasting station. If the genre is news, the transfer time range is 3 hours / day, the drama is 4 hours / day, the news is 1 hour / day, and the total transfer time is 8 hours, the transferable period is Is calculated based on the following equation.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (8) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 8) * 15
= 29.7 days As described above, recorded contents for 29 days can be automatically transferred to the mobile server 200.

  In the automatic transfer process illustrated in FIG. 14, the synchronization control unit 124 determines whether or not there is a recording content in the recording server 100 that is not in the mobile server 200 and that is subject to automatic transfer of a genre. However, the present disclosure is not limited to this, and the synchronization control unit 124 may determine whether or not the recording server 100 has recorded contents that are subject to automatic transfer in a genre that does not exist in the mobile server 200.

  In this case, the automatic transfer management table 165 includes a recording channel designation item for designating a channel for channel automatic recording, and a recording time zone designation item for designating a time zone to be automatically recorded within one day. , An image quality specification item for specifying the recording image quality, an automatic transfer target specification item for specifying for each channel whether or not it is an automatic transfer target, and a genre specification for specifying the genre of the recording content to be automatically transferred It consists of items.

  When the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the content corresponding to the genre designated by the user among the content recorded in the automatic channel recording area 111 is displayed. Copy or move to

  In addition to specifying whether or not to automatically transfer for each channel, the genre of the recorded content can be specified. Genres are specified for all channels at once, not for each channel. The synchronization control unit 124 calculates the transfer period from the usable amount of the channel automatic video recording content transfer area 211. In this case, the synchronization control unit 124 checks the genre information of each recorded content, selects the recorded content to be automatically transferred, and calculates the total transfer capacity of the selected recorded content. Can be calculated. Therefore, the synchronization control unit 124 can calculate the transferable period (number of days) from the recording capacity of the channel automatic video recording content transfer area 211. Therefore, the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the image quality is 15 times, the news is 6 hours / day, the drama is 9 hours / day, the animation is 3 hours / day, When the total is 18 hours, the transferable period is calculated based on the following formula.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (18) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 18) * 15
= 13.2 days As described above, the recorded contents for 13 days can be automatically transferred to the mobile server 200.

  In addition to specifying whether or not to automatically transfer for each channel, the genre of recorded content can be specified for each channel. The genre is specified for each channel. The synchronization control unit 124 calculates the transfer period from the usable amount of the channel automatic video recording content transfer area 211. In this case, the synchronization control unit 124 checks the genre information of each recorded content, selects the recorded content to be automatically transferred, and calculates the total transfer capacity of the selected recorded content. Can be calculated. Therefore, the synchronization control unit 124 can calculate the transferable period (number of days) from the recording capacity of the channel automatic video recording content transfer area 211. Therefore, when the recording capacity of the channel automatic recording content transfer area 211 is 128 GB, the image quality is 15 times, and the average recording target time of each channel is 3 hours / day, the transferable period is based on the following formula: Is calculated.

Transferable period = 128 GB [capacity] / (18/8 Mbps [bandwidth] * 60 s * 60 s * (18) [time]) * 15 [image quality]
= 128 * 1000 / (18/8 * 60 * 60 * 18) * 15
= 13.2 days As described above, the recorded contents for 13 days can be automatically transferred to the mobile server 200.

  16 and 17 are diagrams illustrating an example in which the automatic transfer management table 165 illustrated in FIG. 15 is separated into two.

  FIG. 16 is a diagram showing an example of the channel automatic recording management table, and FIG. 17 is a diagram showing an example of the automatic transfer management table.

  In order to connect the information of the two tables, an item of recording channel ID is added to both tables. The relationship between the two tables is defined by the recording channel ID.

  FIG. 18 is a diagram showing a basic configuration of the mobile server in the present embodiment.

  The mobile server 200 includes a system control unit 221, a synchronization control unit 224, a recording device control unit 225, a playback control unit 226, and a device ID management unit 261.

  The synchronization control unit 224 includes a USB communication control unit 232 or a Wi-Fi communication control unit 231 for performing communication between the mobile server 200 and the recording server 100. Further, the synchronization control unit 224 includes a recording area management unit 223 that manages the automatic channel recording content transfer area 211 and the individual recording content transfer area 212. The synchronization control unit 224 receives information such as recorded content from the recording server 100 and transfers it to the recording device control unit 225, whereby the automatic channel recording content transfer area 211 or the individual recorded content transfer region 212 in the recording device control unit 225. Record the recorded content in.

  The recording device control unit 225 includes a channel automatic recording content transfer area 211 and an individual recording content transfer area 212. The recording device control unit 225 controls the channel automatic video recording content transfer area 211 and the individual video recording content transfer area 212.

  The playback control unit 226 records the recorded content recorded in the automatic channel recording content transfer area 211 or the individual recorded content transfer area 212 in the recording device control unit 225 to the portable information terminal 500, the in-vehicle TV 600, the DLNA compatible TV 410, or the like. Transmit to a device capable of viewing video to achieve video viewing. The playback control unit 226 includes a DLNA / DTCP communication unit 227.

  The system control unit 221 controls the entire mobile server 200.

  When the recorded content in the recording server 100 is encrypted content, and the synchronization control unit 224 is defined as a productization condition or the like for storing in the mobile server 200, the synchronization control unit 224 The recorded content is encrypted in accordance with the rules such as CPRM or AACS, and stored in the channel automatic recorded content transfer area 211 or the individual recorded content transfer area 212.

  When the recorded content in the channel automatic recording content transfer area 211 or the individual recorded content transfer area 212 is encrypted, the playback control unit 226 uses an appropriate encryption such as DTCP / IP based on the encryption method. After processing, the data is transferred to the portable information terminal 500 or the DLNA compatible television 410 or the like.

  The mobile server 200 incorporates a rechargeable secondary battery if it is required to operate in a situation where there is no external power supply when viewed on the portable information terminal 500 or the in-vehicle TV 600. May be.

  Since the mobile server 200 is taken out of the house and is viewed in the portable information terminal 500 or the in-vehicle TV 600 while being put in a bag, only a minimum UI such as power on / off is required. Is provided. The setting of the transfer processing of the recorded content is performed by the recording server 100, and the viewing operation of the stored recorded content is performed by the portable information terminal 500 or the in-vehicle television 600 which is a video viewing device.

  The recording device control unit 225 can determine the capacity of the channel automatic video recording content transfer area 211 according to the recording capacity required for the individual video recording content transfer area 212. The recording device control unit 225 can also define the recording capacity of the channel automatic video recording content transfer area 211 or the minimum capacity to be secured according to an instruction from the recording server 100.

  In the configuration example shown in FIG. 18, a passive device such as a portable HDD (Hard Disk Drive) or a portable SSD (Solid State Drive) is assumed, but a secondary recording device such as a large-capacity SSD is used. It is also possible to implement software using a mobile device such as a tablet computer with

  The mobile server 200 may include a portable recording medium instead of the recording device controller 225 that is a built-in recording medium. The portable recording medium includes a channel automatic video recording content transfer area 211 and an individual video recording content transfer area 212. The recording server 100 manages the media ID of the portable recording medium instead of the device ID. Therefore, even if the mobile server 200 has only one main body, it is possible to store recorded contents with different settings by using a plurality of the portable recording media. For example, only the content broadcast as a news program is automatically transmitted to the first portable recording medium, and the content broadcast as a drama or documentary program is automatically transferred to the second portable recording medium. When viewing recorded content at 500 or the like, the first portable recording medium and the second portable recording medium may be interchanged.

  In this configuration example, the mobile server 200 is assumed to be a passive device such as a portable HDD, a portable SSD, or a media card reader, but a tablet computer having a media card slot such as an SD memory card. It is also possible to implement software using a mobile device such as

  The mobile server 200 may include a built-in recording medium and a portable recording medium. The built-in recording device managed by the recording device control unit 225 includes a channel automatic recording content transfer area 211, and the portable recording medium includes an individual recording content transfer area 212.

  In this configuration example, a passive device such as a portable HDD, a portable SSD, or a media card reader is assumed, but a secondary recording device such as a large-capacity SSD and a media card such as an SD memory card. Software implementation is also possible using a mobile device such as a tablet computer having a slot.

  The built-in recording device managed by the recording device control unit 225 may include the individual recording content transfer area 212, and the portable recording medium may include the channel automatic recording content transfer area 211.

  In this configuration example, a passive device such as a portable HDD, a portable SSD, or a media card reader is assumed, but a secondary recording device such as a large-capacity SSD and a media card such as an SD memory card. Software implementation is also possible using a mobile device such as a tablet computer having a slot.

  Further, the playback control unit 226 may further include an AV decoder and an HDMI communication control unit so that the playback can be performed on a normal HDMI-compatible television via HDMI or the like. In the case of this configuration, the recorded content in the mobile server 200 can be viewed on a home-compatible HDMI television in addition to the mobile device.

  The playback control unit 226 can also be implemented in software in a mobile terminal such as the portable information terminal 500.

  FIG. 19 is a diagram showing a basic configuration of the portable video viewer in the present embodiment.

  The portable video viewer 201 includes a system control unit 221, an input / output control unit 228, a synchronization control unit 224, a recording device control unit 225, a playback control unit 226, a device ID management unit 261, and a display device control unit 251.

  The reproduction control unit 226 includes a DLNA / DTCP communication unit 227, an AV decoder 233, and an HDMI communication control unit 243.

  The video signal reproduced by the AV decoder 233 is output to an external HDMI-compatible television 420 or the like via the HDMI communication control unit 243 and viewed. In addition, the display device control unit 251 includes a small display device 252 including a liquid crystal or an OLED (Organic Light Emitting Diode), a display control unit that performs a down conversion process for displaying a video signal on the display device 252, and the like. 253, and the portable video viewer 201 itself enables viewing of recorded content.

  The configuration of the portable video viewer 201 is based on the configuration of the mobile server 200 of FIG. The configuration of the portable video viewer 201 can also be implemented in a mobile terminal such as the portable information terminal 500.

  Next, the mobile device ID management table 162 that manages device IDs and media IDs in the recording server 100 will be described.

  The mobile device ID management table 162 indicates an item indicating a device ID or a media ID, an item indicating whether each device or each medium supports channel automatic transfer, and a capacity of the channel automatic recording content transfer area 211. And an item indicating whether or not automatic transfer of the individual recording area 112 is supported. The mobile device ID management table 162 can manage the transfer processing contents at the time of synchronization processing for each device or medium.

  Note that the device ID and the media ID may be described in two separate items instead of being described in one item.

  FIG. 20 is a flowchart for explaining a transfer process for transferring the copyable recording content 302 or the move-only recording content 312 in the individual recording area 112 to the individual recording content transfer area 212 in the mobile server 200.

  First, in step S <b> 41, the synchronization control unit 124 determines whether there is a transfer target recording content in the individual transfer management table 166.

  FIG. 21 is a diagram illustrating an example of the individual transfer management table 166.

  As shown in FIG. 21, in the individual transfer management table 166, a recorded content designation item for designating a recorded content that can be a transfer target, an item for designating an automatic transfer target, dubbing 1 or dubbing 10 or the like. The attribute information item indicating the attribute of the recorded content and the item for managing the transferable number of times.

  The transfer process shown in the flowchart of FIG. 20 differs depending on the attribute information. That is, when the recorded content is free broadcast content (10 dubbing content), all the 10 or less devices managed by the recording server 100 can be automatic transfer target devices, but the recorded content is paid broadcasting. In the case of content (dubbing 1 content), since it can be transferred only once, one device becomes a device to be automatically transferred, and it is necessary to designate only one device to be transferred. In addition, since pay broadcast content (dubbing 1 content) can be transferred only once, it is possible to specify that it is not transferred to any device.

  If it is determined that there is no transfer target recording content in the individual transfer management table 166 (NO in step S41), the process ends.

  On the other hand, when it is determined that there is a recording content to be transferred in the individual transfer management table 166 (YES in step S41), in step S42, the synchronization control unit 124 uses the information in the individual transfer management table 166 to transfer. It is determined whether the target recording content is dubbing 1 content (moving target content).

  If it is determined that the transfer target recording content is dubbing 1 content (YES in step S42), in step S43, the synchronization control unit 124 determines whether an automatic transfer destination device is set for the transfer recording content. Judging. Here, when it is determined that the automatic transfer destination device is not set in the transfer recording content (NO in step S43), in step S44, the synchronization control unit 124 determines that transfer is unnecessary, and returns to the process of step S41. .

  On the other hand, when it is determined that the automatic transfer destination device is set for the transfer recording content (YES in step S43), in step S45, the synchronization control unit 124 has not transferred the transfer target recording content to the automatic transfer destination device. Judge whether there is. Here, when it is determined that the transfer target recording content is not transferred to the automatic transfer destination device, that is, when it is determined that the transfer target recording content has been transferred to the automatic transfer destination device (NO in step S45), The process proceeds to step S44.

  On the other hand, when it is determined that the transfer target recorded content has not been transferred to the automatic transfer destination device (YES in step S45), in step S46, the synchronization control unit 124 moves the transfer target recorded content during the next synchronization. Set and return to step S41.

  On the other hand, when it is determined that the transfer target recording content is not dubbing 1 content, that is, when it is determined that the transfer target recording content is dubbing 10 content (NO in step S42), in step S47, the synchronization control unit 124 Then, it is determined whether or not the transferable number of times of the transfer target recording content is zero. If it is determined that the transferable number of times of transfer of the recording content to be transferred is zero (YES in step S47), the process proceeds to step S44.

  On the other hand, when it is determined that the transferable number of times of the transfer target recorded content is not zero (NO in step S47), in step S48, the synchronization control unit 124 determines whether an automatic transfer destination device is set for the transfer recorded content. Determine whether. Here, when it is determined that the automatic transfer destination device is not set in the transfer recording content (NO in step S48), the process proceeds to step S44.

  On the other hand, if it is determined that an automatic transfer destination device is set for the transfer recording content (YES in step S48), in step S49, the synchronization control unit 124 has not transferred the transfer target recording content to the automatic transfer destination device. Judge whether there is. Here, when it is determined that the transfer target recording content is not transferred to the automatic transfer destination device, that is, when it is determined that the transfer target recording content has been transferred to the automatic transfer destination device (NO in step S49), The process proceeds to step S44.

  On the other hand, when it is determined that the transfer target recorded content has not been transferred to the automatic transfer destination device (YES in step S49), in step S50, the synchronization control unit 124 copies the transfer target recorded content at the next synchronization. Set.

  Next, in step S51, the synchronization control unit 124 reduces the transfer count of the transfer target recording content by one, and returns to the process of step S41.

  The individual transfer management table 166 shown in FIG. 21 further includes an image quality designation item for designating the recording image quality for each recorded content and a size item indicating the size (capacity or playback time) of each recorded content. But you can.

  When the picture quality is DR picture quality (Broadcast picture quality of MPEG2), transcoding to mobile compressed data such as MPEG-4 AVC at the time of synchronization processing results in a very long transfer time and is impractical. May be. At this time, a setting for creating a compressed recorded content for transfer while leaving a DR-quality recorded content and a setting for creating a compressed recorded content for transfer without deleting the DR-quality recorded content are selectively performed. . Furthermore, when the recorded content with DR image quality is dubbing 1 content and the setting is made to leave the recorded content with DR image quality, it is necessary to prevent the recorded content for transfer from being played back.

  Further, the individual transfer management table 166 shown in FIG. 21 may further include an item for understanding a situation in which transfer reservations are made to individual devices or media. With this item, the recording server 100 can manage automatic transfer processing to a plurality of devices or media.

  FIG. 22 is a diagram showing a second modification of the flow of recorded content in the recording system of the present embodiment. The recording server 100 shown in FIG. 22 has a configuration in which a check-in / check-out processing unit (CI / CO processing unit) 192 is added to the configuration of the recording server 100 in FIG.

  When the move-only recorded content 311 is transferred to the mobile server 200, the recording server 100 needs to erase (make playback impossible) the original move-only recorded content 311. For this reason, after the recorded content is transferred to the mobile server 200, when the viewing on the mobile server 200 ends or is canceled and the recorded content is deleted from the mobile server 200, the mobile server 200 is synchronized with the recording server during synchronization. Reverse transfer of recorded content to 100.

  The check-in / check-out processing unit 192 may actually reverse transfer the recorded content. In addition, the check-in / check-out processing unit 192 is in an unreproducible state instead of deleting the recorded content in the recording server 100 when transferring the recorded content from the recording server 100 to the mobile server 200 (checkout). It may be. Then, the check-in / check-out processing unit 192 can play back the recorded content in the recording server 100 that has been made unplayable when the mobile server 200 deletes the content and performs synchronization again. The check-in process may be performed by returning to.

  FIG. 23 and FIG. 24 are flowcharts for explaining a modified example of the transfer process for transferring the copyable recording content 302 or the move-only recording content 312 in the individual recording area 112 to the individual recording content transfer area 212 in the mobile server 200. It is.

  Note that the processing in steps S61 to S66 in FIG. 23 is the same as the processing in steps S41 to S46 in FIG.

  In step S67, the synchronization control unit 124 does not delete the transfer target recording content in the recording server 100 when transferring the transfer target recording content from the recording server 100 to the mobile server 200 as the check-in / check-out process. And set to a non-reproducible state (checkout process).

  On the other hand, if it is determined in step 65 that the transfer target recorded content is not transferred to the automatic transfer destination device, that is, if it is determined that the transfer target recorded content has been transferred to the automatic transfer destination device (in step S65). NO), in step S <b> 68, the synchronization control unit 124 determines whether or not the transfer target recorded content has been deleted in the mobile server 200. If it is determined that the transfer target recording content has not been deleted by the mobile server 200 (NO in step S68), the process proceeds to step S64.

  On the other hand, when it is determined that the transfer target recorded content has been deleted by the mobile server 200 (YES in step S68), in step S69, the synchronization control unit 124 becomes in a non-playable state when the synchronization process is performed again. The transfer target recorded content in the set recording server 100 is set in a reproducible state (check-in process).

  Note that the processing from step S70 to step S74 in FIG. 23 is the same as the processing from step S47 to step S51 in FIG.

  FIG. 25 is a diagram showing a third modification of the flow of recorded content in the recording system of the present embodiment. In FIG. 25, the check-in / check-out processing unit 192 of FIG. 22 is targeted for the copy-only recorded content 302 in addition to the move-only recorded content 312.

  In this case, in order to add the copyable recorded content 302 to the target of the check-in / check-out process, the processes of step S75 and step S76 are added to the flowchart of FIG.

  That is, in step S62, when it is determined that the transfer target recorded content is dubbing 1 content (content to be checked in / checked out) (YES in step S62), in step S75, the synchronization control unit 124 It is determined whether or not the transferable number of times of the transfer target recorded content is 1. If it is determined that the transferable number of times of the transfer target recording content is not 1 (NO in step S75), the process proceeds to step S70.

  On the other hand, when it is determined that the transferable number of times of transfer target recorded content is 1 (YES in step S75), in step S76, the synchronization control unit 124 sets to move the transfer target recorded content at the next synchronization. . At this time, when transferring the transfer target recording content from the recording server 100 to the mobile server 200, the synchronization control unit 124 does not delete the transfer target recording content in the recording server 100, but sets it to a non-playable state. Yes (checkout process). Then, the synchronization control unit 124 sets the transfer count to 0, and returns to the process of step S61.

  FIG. 26 is a diagram illustrating another example of the mobile device ID management table.

  In the mobile device ID management table shown in FIG. 26, an individual recording check-in / check-out correspondence item for specifying whether or not to make a check-in / check-out process target for each device ID or each media ID is added.

  FIG. 27 is a diagram showing a first modification of the basic configuration of the recording server 100 in the present embodiment.

  The recording server 100 accesses the optical disc transfer permission server 330 specified by the optical disc 320 reproduced by the optical disc drive 151 via the network, and transfers the optical disc content recorded on the optical disc 320 from the recording server 100 to the mobile server 200. Is transferred from the optical disk transfer permission server 330, and when the transfer permission is acquired, the optical disk content is transferred (copied) to the individual recording area 112. This point is different from the configuration of the recording server 100 of FIG. The optical disk 320 is, for example, a Blu-ray (registered trademark) disk.

  Copying of content recorded on video package media such as optical discs is generally prohibited. However, according to the AACS (Advanced Access Content System) managed copy specification, the content right holder can use a network server or the like. If licensed, a copy can be made as many times as licensed. For this reason, after copying of the content in the optical disc is permitted and stored in the individual recording area 112, it can be managed in the same manner as the pay broadcast content (dubbing 1 content).

  In this case, the optical disc playback / recording control unit 152 accesses the optical disc transfer permission server 330 specified by the optical disc 320 to be played back by the optical disc drive 151 via the network, and receives the optical disc content recorded on the optical disc 320 from the recording server 100. A transfer permission for permitting transfer to the mobile server 200 is acquired from the optical disk transfer permission server 330. The optical disc playback / recording control unit 152 copies the optical disc content to the individual recording area 112 when obtaining the transfer permission.

  The synchronization control unit 124 detects that communication with the mobile server 200 is possible, and the optical disc content copied to the individual recording area 112 is designated by the user as a target to be automatically copied or moved. If so, the optical disk content is automatically copied or moved to the mobile server 200.

  FIG. 28 is a diagram showing a second modification of the basic configuration of the recording server 100 in the present embodiment.

  The recording server 100 transfers the content purchased from the video distribution server 340 to the individual recording area 112. This point is different from the configuration of the recording server 100 of FIG.

  The content purchased through the video distribution service is also managed in the same manner as the pay broadcast content (dubbing 1 content) after being stored in the individual recording area 112 in the same manner as the optical disc content transferred to the individual recording area 112 with permission. be able to.

  However, when content is distributed from the video distribution server 340 or when copying of the optical disk is permitted, the content right holder can specify the number of times of copying. For this reason, the recording server 100 can receive a plurality of times of copying permission, and in this case, it is necessary to manage the number of copies as with the dubbing 10 content.

  The synchronization control unit 124 downloads the distribution content distributed by the video distribution server 340 and records the downloaded distribution content in the individual recording area 112.

  Further, the synchronization control unit 124 detects that communication with the mobile server 200 is possible, and the distribution content recorded in the individual recording area 112 is automatically copied or automatically designated by the user as the object of the move. If it is, the distribution content is automatically copied or moved to the mobile server 200.

  In FIG. 28, the recording system may not include the optical disc drive 151, the optical disc playback / recording control unit 152, and the optical disc transfer permission server 330.

  The content from the optical disc 320 is recorded as the move-only optical disc content in the individual recording area 112, and the content purchased from the video distribution server 340 is recorded as the move-only delivery content in the individual recording area 112 and recorded. The move-only distribution content may be subjected to check-in / check-out processing as a target of the check-in / check-out processing unit 192.

  In such a configuration, the recording server 100 can manage the recorded content in two categories of free recorded content and paid recorded content (paid broadcast content, optical disc content or distributed content), and dubbing 10 content also in terms of user interface. As in the case of managing the number of copies, a transfer operation instruction (transfer reservation) can be made only by being aware of the number of copies.

  In this case, in step S62 of the flowchart of FIG. 23, the synchronization control unit 124 determines whether or not the transfer target recording content is dubbing 1 content, and whether or not the transfer target recording content is optical disc content and distribution content. Also judge. Thereby, the check-in / check-out process for the optical disc content and the distribution content can be realized by the same process as the dubbing 1 content.

  Further, although the attribute information of the individual transfer management table 166 shown in FIG. 21 manages only the dubbing 1 content and the dubbing 10 content, the check-in / check-out process is performed by managing the optical disc content and the distribution content. Can be realized.

  The individual transfer management table 166 may further include an image quality designation item for designating the recording image quality for each recorded content, and a size item indicating the size (capacity or playback time) of each recorded content.

  In addition, the individual transfer management table 166 may further include an item for understanding the status of transfer reservation for each device or medium.

The mobile server 200 further includes a personal data temporary recording area 213 for temporarily recording personal data such as a still image or a moving image captured by a portable information terminal 501 such as a DSC, a video camera, or a smartphone. When synchronization processing is performed between the mobile server 200 and the recording server 100, the personal data in the personal data temporary recording area 213 in the mobile server 200 is recorded by the automatic transfer unit 184 in a method designated by the user. A transfer process 185 transferred to the personal data recording area 113 in the server 100 is performed.

  The synchronization control unit 124 records personal data including still image data or moving image data captured by the user in the personal data recording area 113 of the recording medium.

  The mobile server 200 records personal data. When the synchronization control unit 124 detects that communication with the mobile server 200 is possible, the synchronization control unit 124 receives personal data recorded in the mobile server 200 from the mobile server 200, and receives the received personal data in the personal data recording area 113. To record.

  The synchronization control unit 224 of the mobile server 200 transfers personal data temporarily recorded in the personal data temporary recording area 213 from the mobile server 200 to the recording server 100 when performing synchronization processing with the recording server 100.

  When the personal data is automatically transferred from the mobile server 200, if there is no free space in the personal data recording area 113 of the recording server 100, the recording server 100 automatically increases the capacity of the channel automatic recording area 111 of the recording server 100. The recording capacity of the personal data recording area 113 is ensured. In that case, the user can select whether to reduce the recording period from 30 days to 29 days or to increase the compression rate of some contents or all contents without reducing the recording period in accordance with the area reservation. The recording server 100 includes a UI that can be designated in advance.

  When personal data such as still image data or moving image data is photographed with a portable information terminal such as a DSC or a smartphone, and a large amount of the recording medium of the portable information terminal is used to record the photographed personal data By transferring this personal data to the mobile server 200, the user can shoot without worrying about the recording capacity of the portable information terminal. Normally, when transferring personal data to the mobile server 200, it is necessary to check the storage capacity in the mobile server 200. However, the content in the channel automatic recording content transfer area 211 is deleted and a free area is created based on a method designated in advance by the user, such as deleting the contents of the channel automatic recording content transfer area 211 from old content, for example. The personal data can be transferred without worrying about the capacity of the mobile server 200.

  The recording server 100 accesses the optical disc transfer permission server 330 specified by the optical disc 320 reproduced by the optical disc drive 151 via the network, and transfers the optical disc content recorded on the optical disc 320 from the recording server 100 to the mobile server 200. The optical disc content may be transferred to the individual recording area 112 after obtaining the transfer license for granting the license from the optical disc transfer permission server 330.
