Information recording / reproducing device

Technical field

[0001] The present invention relates to an information recording / reproducing apparatus capable of recording information on a recording medium and reproducing information from the recording medium.

Background art

[0002] A recent DVD (Digital Versatile Disk) recorder has a large-capacity hard disk and can record a large amount of content data (data including video data, audio data, etc.) on the hard disk. It has become. Therefore, when multiple users record their own content on the same recording medium (node disc), their content is managed in a mixed manner, and title management is difficult.

[0003] For such a problem, a content recording apparatus in which a plurality of users manage their own content using a folder display for each user has been proposed (see, for example, Patent Document 1). Also, a video signal recording / reproducing apparatus has been proposed in which users other than the recordr are restricted from viewing and erasing content on the same recording medium on which a plurality of users record or reproduce (for example, Patent Documents).

Problems to be solved by the invention

However, in the content recording apparatus in which a plurality of users described above manage their own content using the folder display for each user, it is easy to manage the titles of their own recorded content. Since the same content is not shared and managed by multiple users, folders cannot be displayed for each user when multiple users share the same content for viewing.

[0006] Further, a video signal recording / reproducing apparatus in which a user other than a recorder is restricted from viewing and erasing content on the same recording medium on which a plurality of users perform recording or reproduction. Therefore, it is possible to share the same content with multiple users for viewing.

1S Recorders give authentication information to content and restrict viewing by content, not content management by user. Therefore, a list of contents that can be viewed by the user cannot be displayed for each user.

[0007] In future information recording / reproducing devices such as DVD recorders, it is expected that the recording capacity of the hard disk will become larger and will be networked. The need to share the same content on a hard disk in a single information recording / playback device is expected to increase (for example, sharing content with the whole family). From the above, multiple users can share the same content

When sharing on a single recording medium, it is easy to manage content for each user, and the user's use, convenience, and information recording / reproducing device are desired.

[0008] The present invention has been made in view of the above circumstances. As an example of the problem, content management for each user is easy when multiple users share and use the same content. Therefore, an object is to provide an information recording / reproducing apparatus that is convenient for the user.

Means for solving the problem

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic configuration diagram of an information recording / reproducing apparatus 1 according to an embodiment of the present invention. The information recording / reproducing apparatus 1 is specifically assumed to be an HDD (Hard Disk Drive) recorder, a DVD (Digital Versatile Disk) recorder, a BD (Blu-ray Disc) recorder, etc., and receives broadcast data. Thus, the received broadcast data is recorded on a predetermined recording medium (eg, hard disk, DVD, etc.). Since data recorded on the recording medium is not limited to broadcast data, hereinafter, data recorded on the recording medium is referred to as content data including video data, audio data, character data, and the like.

Specifically, as shown in FIG. 1, the information recording / reproducing apparatus 1 includes a data input unit 11 for inputting content data from the outside, and recording the input content data in the data storage unit 15 as well as data Data recording for reproducing content data recorded in the storage unit 15 Data to be output to the reproduction unit 12, an input content data or an information output device (for example, a television, etc.) not showing the reproduced content data Output unit 13, information recording / reproducing apparatus 1 System control unit 14 for controlling the whole, data storage unit (for example, hard disk, DVD, etc.) 15, which is a recording medium for recording input content data, and recording / reproducing content data A management information storage unit 16 for storing management information at the time. The management information storage unit 16 manages user management information 161, data management information 162, and reservation management information 163. The user management information 161 is information related to a plurality of users who use the information recording / reproducing apparatus 1, and specifically, as shown in FIG. 2 (a), a user identification number, user It includes items such as name and password for authenticating the user.

Further, the data management information 162 is information for managing the usage rights for the content data stored in the data storage unit 15, and is managed for each user. Here, “use rights for content data” means the right to play, edit and delete content data, and “use rights to content data” means play / edit for content data. This means that both erasing and erasing are possible.

[0017] Specifically, the data management information 162 is a title list for each user as shown in FIG. 2 (b), and there is a right to use the content data stored in the data storage unit 15. In this case, the user is associated with the recorded content data, and the association is managed with a unique link name. The state in which the user is associated with the content data recorded in the data storage unit 15 is the state in which the title link is established, and the data management information 162 is also referred to as link information.

FIG. 3 is a diagram schematically showing the association between the data management information 162 and the content data stored in the data storage unit 15. An arrow extending from the data management information 162 to the data storage unit 15 represents a state in which the title link is extended. In other words, in the state shown in FIG. 3, user A has title links for the contents whose title names are “title 1”, “title 4”, “title 5”, and “title 7”. Therefore (Title Link A—l, Title Link A—2, Title Link A—3, Title Link A—4), “Title 1,” “Title 4,” “Title 5,” and “Title 7” content Data can be used. User B has title links for the titles with titles “Title 2” and “Title 4” (title link B-l, title link B-2). The content data of “Title 4” can be used.

[0019] The reservation management information 163 manages reservation information of content data to be recorded in the data storage unit 15. For example, when receiving and recording broadcast data, the reservation management information 163 is shown in FIG. As shown in c), in addition to information related to reservation such as title name, channel, date and time, usage right information (the power to permit use of content data to be recorded for reservation to which user is stored) is stored.

[0020] Specifically, the system control unit 14 is composed of a CPU that is a main body of calculation / control processing, a ROM in which a predetermined control program is recorded, a RAM that is used as a work area, and the like. Control to record / reproduce data is performed. In particular, in the present embodiment, content data sharing is controlled based on the information stored in the management information storage unit 16 described above.

Next, the operation of the information recording / reproducing apparatus 1 according to the present embodiment will be described using FIG. 4 to FIG.

First, the title list display process will be described with reference to FIG. Here, FIG. 4 is a flowchart of a title list display process for displaying a title list corresponding to the user in accordance with an instruction from the user. Note that the processing shown in FIG. 4 is performed by the CPU of the system control unit 14 (the processing shown in FIGS. 7 to 10 described later is also performed by the CPU of the system control unit 14). In addition, it is assumed that information regarding a user who uses the information recording / reproducing apparatus 1 is stored in the management information storage unit 16 as user management information 161 in advance.

[0023] First, the user operates the user button B1 to which the user is assigned using the remote controller 2 as shown in FIG. Here, the user button B1 corresponds to the user identification number of the user management information 161 described above. For example, specifically, when the user button Bla is operated, the remote controller 2 detects the user identification number 1. Further, when the user button Bib is operated, the remote controller 2 detects the user identification number 2. The remote controller 2 that has detected the user identification number transmits the detected user identification number to the information recording / reproducing apparatus 1. As a result, the information recording / reproducing apparatus 1 receives the user identification number from the remote controller 2 (step S10).

Next, the information recording / reproducing apparatus 1 that has received the user identification number outputs authentication screen information to the information output apparatus connected to the information recording / reproducing apparatus 1 (step S20). As a result, for example, an authentication screen dlO as shown in FIG. play) is displayed.

[0025] The user whose password is asked on the authentication screen dlO uses the numeric key B2 of the remote controller 2 to input the password on the authentication screen dlO. As a result, the information recording / reproducing apparatus 1 receives the personal identification number (step S30), and determines whether or not the received personal identification number is correct (step S40). This is determined based on whether or not the password of the user management information 161 stored in the management information storage unit 16 matches the input password.

[0026] When the personal identification number is correct, the information recording / reproducing apparatus 1 displays a title list corresponding to the user (step S50). Here, displaying the title list according to the user means displaying a list of content data usable by the user corresponding to the received user identification number. For example, a user button assigned to the user A When B1 is operated, as shown in FIG. 6, a title list screen d20 on which the title names of content data that can be used by user A is displayed. The list of content data displayed on the title list screen d20 is displayed based on the data management information 162 stored in the management information storage unit 16, and is displayed as content with title links. Other attribute information (for example, genre name, thumbnail video, etc.) may be displayed in addition to the data title name.

Next, the user selects desired content data from the displayed title list, and instructs the desired operation (playback “edit” deletion). As a result, the information recording / reproducing apparatus 1 performs each instructed operation on the selected content data (step S70).

On the other hand, when the password is correct in step S40, the information recording / reproducing apparatus 1 outputs an error display screen to the information output apparatus (step S60).

[0029] In the present embodiment, the title list is displayed using an authentication process based on a personal identification number, but this authentication process is used to increase security and is necessarily required. It is not something to do. That is, the process of displaying a title list according to a user according to an instruction from the user may be configured by a step force including Step S10, Step S50, and Step S70 in FIG. In addition, for a specific user among a plurality of users, the processing flow may require an authentication process (for example, user A may require an authentication process, user B may not require an authentication process, etc.) ). In addition, this implementation In the embodiment, the user identification button adopting the user button B1 as a user identification button is not limited to this, and the user selection screen is displayed by another button, for example, a navigation button. You may be notified of the user identification number by making a user selection!

Next, content usage right setting processing will be described with reference to FIG. Here, FIG. 7 is a flowchart showing a process when the desired content data (program) is reserved and recorded, that is, when the reservation information is set.

[0031] First, the user sets reservation information for recorded! / And content data. For example, program information such as channel, broadcast date and time, and title name is input. At that time, together with the reservation information, usage right information for the content data, that is, a user who can use the content data is set. Specifically, the right of use is set by the person who sets the right of use (the person who sets the reservation information; the right of use is set for the person who sets the reservation information). Decides whether or not to use. When setting of usage right information is omitted, a user with a predetermined initial value may be set to reduce the setting operation (for example, setting of usage right information is omitted). (For example, granting content usage rights to all users registered in the user management information 161). As a result, the information recording / reproducing apparatus 1 sends the reservation management information 163 to the management information storage unit 16. .

Next, the content recording process will be described with reference to FIG. Here, FIG. 8 is a flowchart showing processing when content data is recorded in the data storage unit 15 based on the reservation information.

First, the information recording / reproducing apparatus 1 records content data in the data storage unit 15 according to the reservation management information 163 stored in the management information storage unit 16 (step S100). Next, the information recording / reproducing apparatus 1 creates a title link between the user and the recorded content data based on the reservation management information 163, and manages this association information (link information) as the data management information 162. The information is stored in the information storage unit 16 (step S110).

Next, the recorded content editing process will be described with reference to FIG. FIG. 9 is a flowchart of the content editing process, which is selected in step S70 of FIG. This is processing when editing the selected content data.

[0035] When the content data selected by the user is edited (for example, partial erasure of content data such as CM cut), the information recording / reproducing apparatus 1 separates from the original content data recorded in the data storage unit 15. Then, a playlist (content data for editing) is created and recorded in the data storage unit 15 (step S710).

Next, the information recording / reproducing apparatus 1 creates a new title link between the user who has performed the editing process and the created playlist, and stores it in the data management information 16 as the data management information 162 (step S720). . After the editing process, when the user selects and reproduces the content from the title list, the playlist is reproduced based on the newly created title link.

FIG. 11 is a diagram schematically showing title links established between the data management information 162 and the content data stored in the data storage unit 15 when a playlist is created. As shown in FIG. 11, when user A edits content data whose title name is “title 1”, a new title link is created between user A and playlist P1. After the editing process, when user A selects and reproduces the content whose title name is “title 1” from the title list, the content data is reproduced according to the playlist P1.

Next, the recorded content erasing process will be described with reference to FIG. FIG. 10 is a diagram showing a flowchart of the content erasing process, which is a process when the content data selected in step S70 of FIG. 4 is erased.

[0039] When the user instructs to erase the selected content data, the information recording / reproducing apparatus 1 erases the title link established between this user and the content data to be erased recorded in the data storage unit 15. (Step S730). In other words, in the present embodiment, each user's content erasure process means the abandonment of its own content usage right, and it means that the content data itself to be erased recorded in the data storage unit 15 is erased. do not do

[0040] Next, the information recording / reproducing apparatus 1 determines whether or not a title link is established between the other user and the content data to be erased recorded in the data storage unit 15 (scanning). Step S740). When there is no user with a title link, that is, when all title links have been deleted, all users have abandoned the right to use the content, so the content to be deleted recorded in the data storage unit 15 Erase the data (Step S750). On the other hand, if there is at least one user who has a title link, the process ends (step S740).

FIG. 12 is a diagram schematically showing a title link created between the data management information 162 and the content data stored in the data storage unit 15 when the content data is erased. As shown in Figure 12, when user A instructs to delete the content data with title name “Title 4”, a title link (title title) is created between user A and the content data with title name “Title 4”. Link A—2) is erased. In addition, when user B instructs to delete the content data with title name “title 4”, a title link (title link B-2) is created between user B and the content data with title name “title 4”. Is erased. As a result, in the content data with the title name “title 4”, all the title links that have been set up with the user are deleted, so the title name stored in the data storage unit 15 is “title 4”. The content data is erased.

Therefore, according to the information recording / reproducing apparatus 1 in the present embodiment, when the usage right information indicating the user who can use the desired content data is set and the content data is recorded. Link information generated between the content data and available users is generated, and the use of shared content data in the same recording medium is controlled based on the link information. Can easily manage content for each user when sharing the same content

That is, since a title list in which content data usable by the user is displayed in a list is output for each user, own content management can be facilitated.

[0044] Also, in the content data editing process, the original content data to be shared is not edited, and each user's playlist is created, so that a plurality of users can edit each. At the same time, since a link is established between the playlist, it is convenient for the user. [0045] Also, in the content data erasure process, the content data is automatically erased when all the title links are erased, so it is not necessary to confirm whether or not someone else has watched the content data. Content data can be erased, content management is easy, and recording medium resources can be used effectively. In the past, when sharing the same content data with multiple people, even if it was viewed by themselves and it was judged that the content data was no longer needed, it was confirmed that others would view it and no longer need it. If you can't do it, you can't erase it.

[0046] In the present embodiment, the content data recorded in the data storage unit 15 is not directly edited and deleted as described above, so that multiple users can use the same content at the same time. It is. For example, for content data with the title name “title 1”, user A can instruct playback and user B can instruct deletion at the same time.

[0047] While the embodiments of the present invention have been described above, various modifications and changes can be made to the embodiments of the present invention without departing from the gist of the present invention. For example, in the above embodiment, the usage right information for the content data is set when the reservation information is set. However, the setting of the usage right information for the content data is not limited to the setting of the reservation information. It may be at the time of. For example, when recording the content data currently being broadcast, the user may instruct the recording process and perform the usage right setting process. In addition, after recording the content data, usage right information for the content data may be set, and a title link may be established between the content data and the user for which the usage right has been set (for example, at the time of reservation setting) If you have set the usage rights for other users because you wanted to encourage other users to watch as a result of viewing the content data, etc. ; In this case, a title link is also established between the content data and other users).

In the above embodiment, for example, program information such as channel, broadcast date and time, title name, etc. is set and reserved recording is performed. However, the present invention is also applied to reserved recording using keywords. Is applicable. For example, the keyword "soccer" is reserved and registered If user A and user B have the right to use the keyword “soccer”, and the content data related to the keyword is recorded in the data storage unit 15, the recorded content data A title link is created between the user A and user B.

[0049] Also, in the above embodiment, the specification is such that the title link is automatically deleted when the content data is played back by the user himself / herself deleting the content data. Also good. In this case, it may be possible to set whether to delete the title link automatically or manually for each user. For users who have not set reservation information, the title link may be automatically deleted when the content data is played. In this case, the specification that automatically deletes the title link may be canceled when a person who is not the user who set the reservation information sets the reservation for the program. The specification may be such that the title link is automatically deleted when a predetermined time elapses after the content data is recorded. Also in this case, it may be possible to set whether to delete the title link automatically or manually for each user.

[0050] Also, in the above embodiment, the power of displaying a list of content data that can be used as a title list. It is also possible to display a flag that makes it possible to distinguish whether the content data has set usage rights. This makes it easier to manage content data because you can know whether you want to view or record content data, or content data recommended by someone else.

[0051] Also, in the above embodiment, since each of a plurality of users sets reservation information, there is a possibility that usage right information is set redundantly for the same content data.

. For example, when user A pre-records content data with the title name “title 1”, he / she sets the usage rights for user B as well as user B, while user B also controls the same content data. This is the case where the user A and other user rights are set during scheduled recording. In this case, a warning may be displayed to the subsequent use right setter so that the use right is not set redundantly. Also, when registering reservation information A confirmation screen (for example, a screen that displays a list of content data for which usage rights information is set based on the booking management information 163) can be displayed, allowing you to check your reservation status. May be avoided.

Furthermore, in the above embodiment, content data shared by a plurality of users is recorded in the data storage unit 15 in the housing of the information recording / reproducing apparatus 1, but is connected to the information recording / reproducing apparatus 1 through a communication network. Record the content data to be shared on the recording medium of another device.

As described above, the information recording / reproducing apparatus according to an embodiment of the present invention is an information recording / reproducing apparatus for recording content data that can be shared and used by a plurality of users on a predetermined recording medium, and the recording medium Usage right information registration means for registering usage right information in which usable users are set with respect to content data to be recorded, content recording means for recording content data on the recording medium, and the content recording means for the recording When content data is recorded on a medium, link information that associates the recorded content data with a user who can use the content data based on the usage right information set by the usage right information registration unit. Link information registration means for registering the content information and when the user uses the content data recorded on the recording medium, Content use judging means for judging whether or not the content data recorded on the recording medium can be used based on the link information registered by the information registration means. When users share and use the same content, content management for each user can be facilitated and user convenience can be improved.
