Description

  The present invention relates to a recording / playback apparatus for dubbing content with protection information onto a recording medium in accordance with the information indicated in the protection information. In particular, when various copy restrictions are set in the recorded content, a dubbing apparatus, a dubbing method, a dubbing program, and a recording medium on which a dubbing program is recorded, which performs dubbing to a recording medium in accordance with the various set copy restrictions And a recording / reproducing apparatus having a dubbing apparatus.

  In recent years, DVR (digital video recorder) with excellent random accessibility, mainly HDD (hard disk drive) recorders and DVD (digital versatile disk) recorders have gained popularity as devices that perform information recording and playback. Yes. Among them, when using digital content, each content in the broadcast wave is given copy restriction information, and a copy according to the copy restriction information attached to each content is copied by the copy protection function of the device that performs information recording / playback. By doing so, the rights of the copyright holder of the video content are protected. The currently defined copy restriction information includes: copy prohibition that prohibits recording on the recording medium itself; copy free that can be copied even after recording on the recording medium; and copy prohibition after recording once on the recording medium. Copy permission. In addition, various methods for presenting information on content with copy restrictions to the user are considered.

The prior art regarding the management method of digital content copy restriction information and the method of presenting it to a user is described in Patent Document 1 below.
JP 2003-22610 A

However, in the current digital broadcasting, most of the content has copy restriction information that permits copying once. For example, once content that is permitted to be copied once is recorded on the recording / reproducing apparatus, it becomes impossible to copy the recorded content again to another recording medium, and it is possible to move only. Specifically, when content having copy restriction information for which copying is permitted once is once copied to the HDD of the recording / playback device, the content copied to this HDD is copied to the HDD of another recording / playback device, an optical recording medium (for example, DVD, etc.) However, although it cannot be copied to another recording medium such as a video tape or a semiconductor memory, the content copied in the HDD can only be moved to another recording medium.
Content movement is a process of copying content to the destination recording medium and erasing the copy source data (that is, the content copied to the source recording medium). If this is interrupted, there is a problem that both the copy source content and the copy destination content cannot be viewed. As a countermeasure against this, there is a policy to ease copy restrictions. For this reason, future increases in copy restriction information and execution of copy restrictions in scene units within the content are considered.

However, an apparatus that performs information recording / reproduction currently on the market regulates copy for each content, and presents copy restriction information to the user for each content. In addition, when a plurality of contents having different recorded copy restrictions are to be copied, the strictest restriction, currently the copy prohibition is determined, and the copyable contents are also moved. In this case, since the contents cannot be viewed at both the movement source and the movement destination as described above, if a plurality of various copy restriction information assumed in the future are added to one content, only the copyable part is copied. May be feasible.
However, in this case, the conventional configuration cannot clearly present the copy restriction information to the user.

(First embodiment)
Embodiments of the present invention will be described below with reference to the drawings.
1. Configuration of Device FIG. 1 is a functional block diagram showing a configuration of a recording / playback device according to the present embodiment.
In FIG. 1, the recording / playback apparatus includes an input unit 10 that receives input from a user, and a program recorded on a first recording medium 500 (or second recording medium 600) described later on a second recording medium 600 (or Dubbing means 100 for dubbing to the first recording medium 500), recording means 200 for recording the broadcasted program on the first recording medium 500 (or second recording medium 600), the first recording medium 500 (or Reproducing means 300 for reproducing a program recorded on the second recording medium 600), a first recording medium 500, and a second recording medium 600 are provided.

In this embodiment, a hard disk (HD) built in a recording / playback apparatus will be described as an example of the first recording medium. The second recording medium 600 will be described by taking a recording medium such as a highly portable optical disk or semiconductor memory as an example. In this case, drive means (for example, a drive device: not shown) for driving the second recording medium needs to be included in the recording / playback apparatus.
In this embodiment, an example in which a program recorded on the first recording medium 500 is dubbed to the second recording medium 600 will be described. Conversely, in other words, a program recorded on the second recording medium 600 is recorded. It is also possible to dubb to the first recording medium 500.
In the present embodiment, the program A is recorded on the first recording medium 500 via a broadcast wave. However, the program A is recorded on the first recording medium 500 by network distribution or the like. May be.
The display device 400 for displaying the broadcasted program and the program recorded on the first recording medium 500 (or the second recording medium 600) may be separate from or integrated with the recording / playback device. .

The operation of the apparatus shown in FIG. 1 will be described. The recording unit 200 records a program sent via a broadcast wave in accordance with a recording command from the user input from the input unit 10. In addition to the program content itself, the program included in the broadcast wave includes scene information having scene copy restriction information corresponding to each scene (or scene) constituting the program, and this scene information is also included in the recording of the program. Recording is performed on the first recording medium 500.
The dubbing means 100 copies (or dubbes) a program (here, referred to as program A) once recorded on the first recording medium 500 to the second recording medium according to the scene copy restriction information.
At this time, for example, when the scene copy restriction information in a certain scene constituting the program A is copy prohibited or the copy permission count is 0, the corresponding scene is not copied to the second recording medium 600.

  That is, a scene that can be copied to the second recording medium 600 is copied. Therefore, as a result of copying the program A to the second recording medium 600, the generated program A1 is the same as the content of the program A as long as the scene copy restriction information for all scenes constituting the program A can be copied. Otherwise, only the scenes that can be copied from among the scenes constituting the program A are displayed. When the program A1 is copied, scene information corresponding to the program A1 is also recorded. If the scene copy restriction information of the copy source scene of the program A before copying is information indicating the permitted number of copies, the scene copy restriction information of the corresponding scene of the copy destination program A1 cannot be further copied. What is necessary is just to record so that it may become the information to show (for example, copy prohibition or copy permission frequency is 0). By doing so, it is possible to suppress copying using the program A1 recorded on the second recording medium 600.

Next, more specific configurations of the input unit 10 and the dubbing unit 100 will be described with reference to FIG.
The dubbing means 100 includes a title copy restriction information extraction means 102, a title copy restriction determination means 103, a scene copy restriction information extraction means 104, a scene copy restriction determination means 105, a title dubbing means 106, and a scene thumbnail generation / display. Means 107, copy start determination means 108, and scene dubbing means 109 are provided.
The title operation selection means 101 is an example of the input means 10 such as a remote control for controlling the recording / playback apparatus and an input button provided in the recording / playback apparatus.
Also, title copy restriction information extraction means 102, title copy restriction determination means 103, scene copy restriction information extraction means 104, scene copy restriction determination means 105, title dubbing means 106, scene thumbnail generation / display means 107, The copy start determination means 108 and the scene dubbing means 109 are each constituted by program data, and the program data may be executed by an arithmetic device such as a CPU in the recording / playback apparatus, or the above-described means may be executed. The signal processing circuit may be used, or may be realized using an integrated circuit such as an LSI that executes the above-described means.
Further, the program data may be recorded in advance in a memory or the like in the recording / playback apparatus, or may be stored in a readable recording medium, and may be configured to read and execute the contents recorded on the recording medium. .

An operation relating to the recording / reproducing apparatus of the present embodiment will be described.
Information that allows the user to identify the content in the recording medium is displayed on the display screen of the display device 400 from the first recording medium 500 that stores the recorded content.
For example, when the recording / playback apparatus receives a remote control signal corresponding to a command such as title list display in accordance with a user instruction, the content management means (not shown) stores the recorded program (content) in the first recording medium. A thumbnail of each title is generated based on the content information acquired from 500 and a signal including an instruction to display is sent to the display device 400.
The display device 400 receives this signal and displays, for example, a title list shown in FIG. 11 on the display screen of the display device. The display screen shown in FIG. 11 indicates that programs A to D are included in the first recording medium. In FIG. 11, the thumbnail image of program A is surrounded by a thick frame, which indicates that it is a selection target by the title operation selection means 101. The title operation selection means 101 can change the target surrounded by a thick frame to the program B, the program C, or the program D by operating an input key (for example, an arrow key, a numeric key, etc.).

When the user operates the title operation selection unit 101 to select a predetermined title from the title list and then instructs execution of dubbing processing (that is, copy processing) for the selected predetermined program (or title), the title operation is performed. The selection means 101 sends a signal corresponding to this to the title copy restriction information extraction means 102. As described above, the title operation selection unit 101 is a dubbing selection unit that selects a program recorded on the recording medium 500 and instructs the dubbing to another recording medium 600.
When the title copy restriction information extraction unit 102 receives the selected title information sent from the title operation selection unit 101, the title copy restriction information extraction unit 102 extracts title copy restriction information related to the selected title (program).
Here, the title is one recorded program (content) from the start to the end of recording, and the selected title information is a title number selected by the user for the dubbing process. When the user selects a process other than dubbing such as playback after selecting the title, the title operation selection unit 101 notifies the playback unit 300 of the selected title information, and the playback unit plays back the program corresponding to the selected title. However, description of these processes is omitted here.

As described above, when the title copy restriction information extraction unit 102 receives the selected title information transmitted from the title operation selection unit 101, the title copy restriction information extraction unit 102 extracts the title copy restriction information of the title based on the selected title information, Together, it is sent to the title copy restriction determination means 103. Here, the scene is a continuous section having the same copy restriction information, and the title copy restriction information is a flag indicating whether or not all the scenes existing in the title are copy-prohibited.
The title copy restriction determination unit 103 determines the title copy restriction information, and provides the selected title information to the scene copy restriction information extraction unit 104 when all scene copies in the title are not prohibited. If all scenes are copy-inhibited, the process ends without executing dubbing.

The scene copy restriction information extraction unit 104 extracts scene copy restriction information of each scene included in the title based on the selected title information. The scene copy restriction information is information (or a flag) indicating the contents of copy control (for example, the number of permitted copies, copy free, copy prohibited) for each scene constituting the program. Based on the scene copy restriction information, copy restriction mixed information is generated and provided to the scene copy restriction determination unit 105 together with the selected title information.
The scene copy restriction determination unit 105 determines the received scene copy restriction mixed information, and when copy restriction information is mixed (that is, the copy prohibition or copy permission count is included in the scene copy restriction information of at least one scene constituting the program). Includes a content that is 0, and the scene copy restriction information of other scenes includes a content that is 1 or more times permitted to copy or content that indicates copy free) includes a scene that cannot be copied to a scene constituting a program to be dubbed A signal for displaying a message indicating this is sent to the display device 400. As described above, the scene copy restriction determination unit 105 is a copy restriction determination unit that determines whether or not scene copy restriction information is set for each scene of the program selected by the title operation selection unit 101. The scene copy restriction determination unit 105 determines that the scene copy restriction information is set for each scene of the selected program when it is determined that the scene copy restriction information is set for each scene of the program selected by the copy restriction determination unit. It is a message generation means for generating a message that information is set.

Upon receiving this, the display device 400 displays a message window as shown in FIG. 13, for example, on the display screen. In the message window shown in FIG. 13, selection items “execute copy” and “cancel” are displayed together, and the user can select and execute any of the above items by operating, for example, a key provided on the remote controller. It is configured as follows.
The scene copy restriction determination unit 105 notifies the selected title information to the scene thumbnail generation / display unit 107 when, for example, the user operates the remote controller and selects “execute copy”.
When the user operates the remote controller and selects “CANCEL” shown in FIG. 13, the process ends without performing dubbing.
The title dubbing means 106 acquires the title information based on the selected title information, and copies it to the second recording medium 600 to form the program A1, and creates the scene information of the copied program A1 and ends the process. .
The scene thumbnail generation / display unit 107 acquires the title information based on the selected title information, and generates a thumbnail of each scene constituting the program. Further, a signal for displaying the scene copy restriction information given for each scene together with the generated thumbnail is output to the display device 400.

Upon receiving this, for example, as shown in FIG. 12, the display device 400 displays the scene copy restriction information given for each scene together with the generated thumbnail on the display screen. As shown in FIG. 12, selection items of “copy execution” and “cancel” are displayed together with the scene copy restriction information, and the user operates any of the above items by operating a key provided on the remote controller, for example. It is configured to allow selective execution.
For example, when the user operates the remote controller and selects “execute copy” shown in FIG. 12, the copy start determination unit 108 informs the scene dubbing unit 109 of the selected title information. If “Cancel” is selected, the process ends without executing dubbing.
The seeding means 109 obtains the title information based on the selected title information, copies only the scenes that can be copied to the second recording medium 600 to form the program A1, and stores the scene information of the copied program A1. Create a new title by creating it. After creating a new title, the process ends.

  In this example, the process of displaying the screens of FIGS. 12 and 13 can be recognized as including at least the scene that the user cannot copy to the program to be tabbed if the process of displaying the screen of one of the screens is performed. Therefore, the process for displaying either one of the screens is not necessarily performed.

2. Next, the operation of the recording / playback apparatus configured as described above will be described.
FIG. 3 is a flowchart showing a processing procedure for explaining an operation of dubbing content in the recording / playback apparatus of the present embodiment. In FIG. 3, the title operation selection means 101 sends selected title information to the title copy restriction information extraction means 102 when a dubbing process is selected after a title is selected by a user operation (S201).
The title copy restriction information extraction unit 102 extracts title copy restriction information based on the selected title information, and the title copy restriction determination unit 103 determines that the title copy restriction information is false (that is, copies each scene constituting the title). If there is information regarding the restriction and the information regarding the copy restriction of at least one of the scenes is copy permission), the selected title information is notified to the scene copy restriction information extracting unit 104 (S202N). At this time, if a command for displaying a message indicating that there is information on copy restrictions for each scene constituting the title is displayed, the user can restrict copying to a program to be dubbed before dubbing. Since it is possible to know that a certain scene is included, it is possible to accurately determine whether or not to perform dubbing.
On the other hand, when the title copy restriction information is determined to be true (that is, when all scenes constituting the title are prohibited from being copied together, or there is information on copy restriction for each scene constituting the title, and all scenes are copied) If the information regarding the restriction is copy prohibition), the process ends (S202Y).

The scene copy restriction information extraction unit 104 extracts the remaining number of times that each scene of the selected title can be copied, and generates and displays copy restriction mixed information (S203).
The scene copy restriction determination means 105 notifies the selected title information to the title dubbing means 106 when there is no need to display the copy restriction mixed information (that is, when all scenes constituting the title can be copied) (S204). N) in Then, the title dubbing means 106 copies the selected title and ends the process (S205).
On the other hand, after the copy restriction mixed information is displayed, if there is a dubbing instruction from the user, the selected thumbnail information is notified to the scene thumbnail generation / display unit 107 (Y in S204). The scene thumbnail generation / display unit 107 generates a thumbnail for each scene based on the selected title information, and displays it together with the scene copy restriction information (S206).
The copy start determination unit 108 receives an input of copy execution selection and dubbing cancellation by a user operation (S207). When copy execution is selected by an operation by the user, the selected title information is notified to the scene dubbing means 109 (Y in S208). If dubbing cancellation is selected, the process ends (N in S208).
The seeding means 109 copies a scene that can be copied based on the selected title information, generates a new title, and ends the process (S209).

  In the flowchart of FIG. 3, only when the result in S204 is Yes, the process in S206 (that is, the scene thumbnail generation / display unit 107 generates a thumbnail for each scene based on the selected title information, together with the scene copy restriction information. (Processing for display) is executed. However, even if No in S204, the process in S206 may be executed. In this way, it is possible to know the current copy restriction information (especially the number of permitted copies) of each scene before performing dubbing. This is effective because when the number of permitted copies of a scene included in a program to be dubbed approaches 0, a more careful judgment can be made regarding the execution of dubbing.

FIG. 4 is a flowchart showing a processing procedure in which the scene copy restriction information extracting unit 104 generates and outputs copy restriction mixed information in step 203. In FIG. 4, the scene copy restriction information extraction unit 104 sets the first scene (in this example, the first scene is the scene 1) among the scenes included in the selected program as a processing target (S300). Next, the scene copy restriction information of the set scene to be processed is acquired (S301). Next, it is determined whether the remaining copy count of the set scene to be processed is 0 or copy prohibition (S302). If the set remaining copy count of the scene to be processed is 0 or copy prohibited (S302Y), it is determined that the copy restriction mixed information needs to be output (S303), and a command to display the copy restriction mixed information is displayed on the display device. After sending to the process, the process ends. If the set remaining copy count of the scene to be processed is not 0 (S302N), it is determined whether or not the determination of all scenes in the title has been completed. If all scenes in the program have not been determined (N in S304), the scene to be processed is set as the next scene of the currently selected scene (S305), and the process returns to step 301.
On the other hand, if it is determined in S304 that all scenes have been determined (Y in S304), it is determined that there is no need to output copy restriction mixed information (S306), and the process ends.
In this way, it is possible to determine whether or not a program to be tabbed includes a scene that cannot be copied.

  In FIG. 3, in S302, the copy restriction mixed information is output according to the determination whether the set remaining copy count of the scene to be processed is 0 or copy prohibition. After the determination in S302, flag information for controlling whether to output copy restriction mixed information (for example, if Yes in S302, flag information is set to true, and if No in S302) In this case, the flag information is set to false) may be recorded in association with the target content, and when the copy restriction mixed information is displayed, the display may be controlled according to the flag information.

FIG. 5 is a flowchart showing a processing procedure for generating a thumbnail of the scene in step 206 and displaying it together with the scene copy restriction information. In FIG. 5, the scene thumbnail generation / display unit 107 acquires AV information of the title selected for dubbing (S401). Next, among the scenes included in the selected title, the first scene (in this example, the first scene is set as scene 1) is set as a processing target (S402). Next, scene start position information corresponding to the selected scene is acquired (S403). Next, a thumbnail image is generated from the video included in the acquired scene. Here, the scene image at the time stored in the acquired scene start position information is created as a thumbnail (S404). Next, it is determined whether thumbnails have been created for all scenes included in the title (S405).
If the thumbnail generation processing for all scenes has not been completed (N in S405), the scene to be processed is set as the next scene of the currently selected scene (S406), and the process returns to step 403.

On the other hand, when the thumbnail generation processing for all scenes is completed (Y in S405), the first scene (in this example, the first scene is set as scene 1) among the scenes included in the selected title is set as the processing target. (S407).
Next, scene copy restriction information corresponding to the set scene is acquired (S408). Next, an instruction is given to display the thumbnail of the scene created in the above-described process and the acquired scene copy restriction information on the display screen of the display device (S409).
Next, for all scenes, it is determined whether or not the instruction to display the corresponding thumbnail and scene copy restriction information has been completed (S410).
If the instruction to display the corresponding thumbnail and scene copy restriction information is not completed for all the scenes, the scene to be processed is set as the next scene of the currently selected scene (S411), and the process returns to step 408.
If all the scenes have been instructed to display the corresponding thumbnails and scene copy restriction information, the process ends.
By doing so, it becomes possible to display thumbnails corresponding to each scene and scene copy restriction information on the display screen. An example of this display screen is shown in FIG.

FIG. 6 is a flowchart showing a processing procedure for performing a dubbing process on the title selected by the scene dubbing means 109 in step 209 and copying it to another recording medium. In FIG. 6, the scene dubbing means 109 sets the first scene (in this example, the first scene is scene 1) among the scenes included in the title as a processing target (S500).
Next, the scene dubbing unit 109 acquires copy restriction information of the set scene (S501). It is determined whether the remaining copy count of the set scene is 0 or copy prohibition (S502). If the set remaining copy count of the scene is 0 or copy prohibition (Y in S502), the process proceeds to step 506. If the remaining copy count is neither 0 nor copy prohibition (N in S502), the start position information acquisition of the set scene (S503) and the end position information acquisition of the scene (S504) are performed, and the above-described position information in the AV information The scene defined in (1) is copied to another recording medium (S505).
Next, it is determined whether or not copying has been completed for all scenes (S506). If the determination of all the scenes has not been completed (N in S506), the scene to be processed is set as the next scene of the currently selected scene (S507), and the process returns to step 501.

With this configuration, it is possible to perform dubbing according to scene copy restriction information for each scene in which different copy restriction information is set in the program. As for the scene information of the program for which dubbing has been selected, as for the recording source title, as shown in FIG. 9 (a), the scene copy restriction information in which the number of times of copying is set for what was actually copied. Is set (or rewritten) by subtracting 1 from each.
As for the scene information in the title information of the recording destination, as shown in FIG. 9 (b), this information is set to “prohibited” when the scene copy restriction information in the recording source scene sets the number of copies. For those that are copy-free, set to “free”.
With this configuration, it is possible to copy from the recording medium of the recording source a predetermined number of times, and it is possible to suppress further copying from the recording medium of the recording destination.
The timing for changing the scene copy restriction information corresponding to each scene with respect to the recording source scene information, and the timing for recording the scene information to the recording medium of the recording destination may be performed every time copying of each scene is completed, It may be performed after the copying of the scene is completed.

FIG. 7 is a diagram showing a specific example of a program having different copy restriction information for each scene. In FIG. 7, the program A corresponds to a scene where the presenter speaks (hereinafter referred to as scene 1), a scene where the singer receives an interview (hereinafter referred to as scene 2), a scene where a song is sung (hereinafter referred to as scene 3), and CM. It is assumed that a scene (hereinafter referred to as “scene 4”), a scene spoken by the presenter (hereinafter referred to as “scene 5”), and a scene in which a video flows (hereinafter referred to as “scene 6”) are included.
The title information is given scene copy restriction information which is information indicating copy restrictions for each scene included in the program A. When the program A is dubbed to another recording medium, the scene copy restriction information is stored in the title information. It is configured to be rewritten as necessary.

FIG. 8 is a diagram showing a specific example of title information when the program A shown in FIG. 7 is recorded on a recording medium.
The title information 701 indicates information on the entire title. The title information 701 includes, for example, AV information 702 that is program content (title main body), management information 703 (for example, marking information of chapters and playlists, a table of AV information memory addresses, a time that links the size and time of AV information) Table) and title copy restriction information 704 are held. Here, the title copy restriction information holds “true” if all scenes of the title are copy-prohibited, and “false” otherwise, and all scenes included in the title are copy-prohibited. It is a flag for determining whether or not. The title information 701 holds scene start position information 706, scene end position information 707, and scene copy restriction information 708 as information for each scene. The scene copy restriction information sets how many times copying is permitted for the corresponding scene, copying is prohibited, or copying is permitted without limitation (that is, copy free).

An operation when the title list shown in FIG. 11 is displayed and the user selects the program A in the title list as a dubbing control will be described. At this time, it is assumed that the program A has the title information shown in FIG.
This dubbing operation will be described with reference to the flowchart shown in FIG. First, in step S201, title copy restriction information is acquired. As shown in FIG. 8, since “false” is set in the title copy restriction information, “No” is determined in S202, and the process proceeds to S203. In S203, since the corresponding scene copy restriction information for scene 6 is set to copy prohibition, copy restriction mixed information is generated. FIG. 13 is a diagram for explaining an example of copy restriction mixed information. As shown in FIG. 13, a description will be given by taking as an example a display screen in which a screen indicating the content that there is a scene that cannot be dubbed exists in the selected program on the title list screen shown in FIG. The screen shown in FIG. 11 may be cleared and the screen having the above-described content may be displayed.
Next, after confirming the screen shown in FIG. 13, when the user instructs dubbing, it is checked in S204 whether at least one of the scenes in the scene information A705 indicates copy prohibition. In this example, since “prohibition” indicating copy prohibition is set in the copy restriction information of scene 6, “Yes” is determined in the determination of S204, and the process proceeds to S206. In S206, a thumbnail for each scene is generated, and copy restriction information for each scene is read and output together with it. An example of the output display screen is shown in FIG.

In FIG. 12, scene 1 is “5 times”, scene 2 is “3 times”, scene 3 is “2 times”, and scene 5 is “5 times”, and scene 4 is copy-free. Information indicating “free” and “prohibition” indicating that the scene 6 is copy prohibited is output to the display screen together with a thumbnail of the corresponding scene. In this way, if it is configured to display together with the thumbnails of the respective scenes, the user can easily understand which contents in the program are subject to copy restrictions.
When the information output on the display screen is confirmed and the user instructs execution of copying program A, execution of dubbing of the scene is started.

At the end of the dubbing execution, the recording medium of the recording source shows the number of permitted copies of scene 1, scene 2, scene 3, and scene 5 in the scene information A as shown in FIG. A value obtained by subtracting 1 from the value is set.
Since copying of scene 6 is prohibited, no recording is made on the recording medium of the recording destination.
In addition, in order to prevent copying to the recording medium of the recording destination using the recording destination data, the scene copy restriction information of scenes 1 to 3 and scene 5 is “prohibited” as shown in FIG. 9B. To be set. In this way, only the copy-free scene 4 can be dubbed using the data of the recording destination program A.
Or, for the scene 4, if the copy restriction information of the recording destination scene 4 is set to “prohibited” and the title copy restriction information is changed to “true”, further dubbing from the recording medium of the recording destination is completed. Can be suppressed.
