Description

  The present invention provides a recording / reproducing apparatus using a cartridge type hard disk standardized in accordance with an international standard called iVDR (Information Versatile Disk for Removable Usage) as a recording medium. The present invention relates to a recording / reproducing apparatus that performs chapter editing when recording content by using various comment information recorded by an unspecified number of people acquired from.

  In addition to VTRs that have been widely used in the past, devices that use DVDs (Digital Versatile Disks) and hard disks (Hard Disk Drives) as recording media have been widely used as devices for recording and reproducing content consisting of video and audio. I'm starting. At present, DVDs having a large storage capacity of several gigabytes and hard disks of several hundred gigabytes are in widespread use. By using high-efficiency encoding technology such as the MPEG2 system, contents can be stored for several hours to several tens of hours. Recording is possible easily.

In the recording / reproducing apparatus using these hard disk and DVD recording media, the conventional V
Like the TR, a scheduled recording function is provided, so that a desired number of programs can be continuously recorded on the same medium. In such a case, a large number of contents are continuously recorded. Therefore, in order to improve the convenience for the user, a desired part of each program (content) or in the program (in the content) is separated. Therefore, chapter information is usually created and associated.

  For example, it is also realized that chapter information is created in accordance with the recorded audio mode. For example, if a program such as a movie or a drama was broadcast with monaural audio or double audio, chapter information is added by detecting a change in audio mode at the part where the commercial broadcast during the program broadcast switches to stereo audio It is possible to make it. However, in this case, if the program itself is the same stereo sound as the commercial, the break cannot be detected, so that chapter information cannot be added.

  As a recording / reproducing apparatus capable of editing chapter information, for example, there is a recording / reproducing apparatus with an automatic chapter creation function disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 2002-152636). This recording / playback device with automatic chapter creation function is configured to automatically create chapters by setting the position where recording was paused during recording and then resumed as the chapter boundary. is there.

  However, in such a chapter editing method, the chapter information and the recorded program are in a one-to-one relationship, that is, when a plurality of programs are continuously recorded, the breaks in each program and the desired program in the program are recorded. In order to attach chapter information to each part, it is necessary to add chapters sequentially while performing playback or search operations for all recorded programs. The longer the recording time, the more time is required for the work. . In addition, it is not considered to automatically add chapters at desired locations in the program.

  In order to eliminate such inconvenience, a chapter information management method as disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2005-217875) has been proposed. In this management method, when recording chapter data created by a user, an identifier associated with the chapter data is registered in the chapter list, and the identifier is registered in the recording information of the recording list. And the identifier associated with the chapter data already recorded in the first identifier field provided in the recording reservation information of the reservation list is designated as the corresponding recording information of the recording list after the recording ends. The recorded data and chapter data are associated with each other by duplicating in the provided second identifier field.

  In recent years, in order to cope with the digitization of television broadcasting, digital recording / reproducing apparatuses such as DVD recorders and HDD recorders have become widespread. One of the functions of these digital recording / reproducing apparatuses is a time shift function. The time shift function is a function that enables the currently recorded content to be played back in parallel while recording the content (video information). By using the time shift function, the user can start playback from a recorded scene of the content being recorded (for example, a game start scene in the case of soccer) and can also continuously perform the recording process. . Accordingly, for example, when a soccer game is being recorded, it is possible to view the game from the scene where the game starts at any time without waiting for the completion of the recording (for example, the end of the game).

  A digital recording / reproducing apparatus having a time shift function is disclosed in, for example, the following Patent Document 3 (Japanese Patent Laid-Open No. 2007-310955). This recording / reproducing apparatus accepts an editing instruction for data being recorded during time shift reproduction. The input editing instructions are temporarily stored in a storage device such as a hard disk, and the editing instructions stored in the storage device are automatically reflected in the recorded data when the recording process and the time shift playback process are completed. It is comprised so that it may be. As the editing instruction, for example, a chapter setting instruction or a manual deletion instruction of video information is accepted. The accepted instruction can be changed any number of times before reflection.

  Further, in recent years, contents such as video, music, programs, and the like have increased in data quality and image quality, and the amount of data has increased remarkably. In order to record this, a large-capacity storage medium is required. In addition, in order to expand good content that is generally provided, a technology that effectively protects copyright must be provided, such as restricting illegal duplication of content. Furthermore, there is a demand for users to store content in a storage medium that can be freely carried and to connect (install) the storage medium to an arbitrary electronic device.

  In order to satisfy such a demand, a recording / reproducing apparatus using a cartridge type hard disk standardized in accordance with an international standard called iVDR (information Versatile Disk for Removable usage) as a recording medium is also provided. According to this standard, content that is copyright-protected is acquired and recorded in iVDR without changing the copyright protection state.

For this reason, the recording / reproducing device 20 is received when the cartridge 100 is attached to the recording / reproducing device 20 for receiving a video signal and an audio signal input from the antenna input terminal 209, the HDMI terminal 213, and the like. For example, a signal processing circuit for recording the recorded video signal on the hard disk and reproducing the video signal recorded on the hard disk.

  FIG. 5 is a block diagram showing a configuration of the recording / reproducing apparatus 20 according to the embodiment of the present invention in which the cartridge 100 can be mounted. The recording / reproducing apparatus 20 includes a tuner 21, an iVDR attachment unit 22 in which a cartridge 100 (hereinafter also referred to as a hard disk) based on the iVDR standard is attached, a network connection unit 23, a viewing control unit 24, a recording / reproduction control unit 25, and a WEB browser 26. The video / audio output unit 27 is provided. These constituent elements are provided in a recording / reproducing apparatus corresponding to a general iVDR standard. The recording / reproducing apparatus according to the present invention further includes a comment management unit 28 and a chapter editing processing unit 29 in addition to the above components.

  The tuner 21 receives the broadcast wave of the channel selected by the user, sends it to the video / audio output unit 27 via the viewing control unit 24, and the output signal output from the video / audio output unit 27 is a television receiver (TV). ) Etc. In addition, the recording / reproducing apparatus 20 has a network connection function, connects to the Internet or a home network through the network connection unit 23, specifies desired content on the network using the WEB browser 26, and The audio output unit 27 can be used for output. The functions of these units are the same as those of a general recording apparatus having a network connection function.

  The broadcast wave received via the tuner 21 is recorded (recorded and saved) on the cartridge 100 attached to the iVDR attachment unit 22 via the recording / reproduction control unit 25. Therefore, the function and operation of the recording / playback control unit 25 is different from that of a normal broadcast receiving apparatus, and controls recording generation processing in accordance with the iVDR standard. That is, the recording / playback control unit 25 encrypts the content on the cartridge 100 based on the encryption method defined by the iVDR standard. Further, when the content recorded on the cartridge 100 is read and reproduced, the content is decrypted based on the encryption method and output from the video / audio output unit 27. Further, when access restriction information is given to the content for copyright protection based on the iVDR standard, the recording / playback control unit 25 performs a recording / playback process based on the access restriction information.

  Next, the chapter editing procedure according to the present invention will be described. The comment management unit 28 can acquire comment information stored in a comment storage server (not shown) via the network connection unit. As described above, the comment accumulation server is a server provided by the social network system. For example, if the object of interest is a specific movie, a server operated by a movie distribution company or a broadcasting company that provides television broadcasting is assumed. Or, a server that can write impressive introductions of scenes, etc. may be a general server connected to the Internet or a WEB site, so that comments regarding broadcast programs written on these servers or WEB sites are acquired. It can also be configured.

  Comments written by an unspecified number of users are accumulated in the comment accumulation server in time series. Further, for example, when content is provided by television broadcasting, it can be stored in the comment storage server for each broadcast channel by content title. An unspecified number of users who are interested in the movie can access the comment storage server and refer to (read) their writings. In addition, you can write your own comments on the referenced writing. The comment management unit 28 acquires a comment from such a comment storage server.

  The comment management unit 28 is used as a comment storage server based on the title of the content (hereinafter referred to as “recorded content”) recorded on the cartridge 100 mounted on the iVDR mounting unit 22 by the recording / playback control unit 25, broadcast date and time, broadcast station, and the like. The comment information regarding the recorded content is acquired and stored in the cartridge 100. It is not necessary to acquire the comment information at the time of recording the content and store it in the cartridge 100. The comment information may be acquired when the chapter is edited. Of course, comment information may be acquired and stored when recording content.

  When chapter editing is performed by the chapter editing processing unit 29, the comment management unit 28 acquires (reads out) the comment information stored in the cartridge 100 and sends the comment information to the chapter editing processing unit 29. The chapter edit processing unit 29 analyzes the comment information sent from the comment management unit 28. There are several methods for analyzing comment information. For example, the first method is a method in which a chapter is set and edited based on a predetermined numerical value (the number of comments) set in advance in a part of the content in which a comment exceeding a certain number or less than a certain number is written. is there. The second method is a method in which a user sets one or a plurality of keywords, and sets and edits a chapter in a content portion where a comment including the set keywords is written.

  The chapter editing process according to the present invention is preferably performed by user selection. In this case, the recording / playback apparatus may be provided with a chapter editing start button, or the chapter editing process may be selected on the menu screen so that the recorded content to be subject to chapter editing can be selected. When acquiring comments, editing chapters, and recording content at the same time, simply operate the chapter editing start button during recording, and the broadcast station (channel) and broadcast time being recorded are automatically known. In particular, the content for the recorded content can be acquired from the content storage server and edited in chapter. If a setting is made so that chapters are automatically assigned at the time of recording reservation, it is possible to automatically acquire a comment from the comment storage server and execute chapter editing when recording starts. In addition, when an iVDR recording medium is loaded, chapter editing can be automatically executed on recorded content to which no chapter is assigned.

  FIG. 6 is a diagram for explaining the concept of such chapter editing. FIG. 6 is a graph showing the recorded content m around the time axis t, the number of comments on the vertical axis, and the number of comments at each time as a predetermined threshold value n as a bar graph. Assuming that the broadcast start time of the recorded content subject to chapter editing is Ts and the broadcast end time is Te, the recorded content recorded in the cartridge 100 is recorded from the start of the broadcast to the end of the broadcast as shown in m in FIG. Has been.

  On the other hand, comments are written to the comment storage server in real time from an unspecified number of viewers who are watching the broadcast. In the comment, the channel (or broadcast station name) of the broadcast station to be written is described, and the posting time is given by the server. FIG. 6 is a bar graph showing the number of comments at each time. It can be seen that comments were written exceeding the threshold value n at times ta, tb, tc, and td.

  Therefore, chapters ch1, ch2, ch3, and ch4 are set at the respective positions of the recorded content corresponding to times ta, tb, tc, and td. The user can play back the recorded content from any of the positions ch1, ch2, ch3, and ch4 where the chapter is set. In the chapter setting, for a comment acquired from the comment storage server, for example, the number of written comments per minute can be calculated every minute.

  In this way, for example, if the recorded content is a soccer game, the number of written comments will naturally increase at the moment of the goal, so that a chapter can be set at the scene corresponding to the recorded content. Can start playback from the goal scene.

  In the case of the first method, the chapter edit processing unit 29 analyzes the comment information regarding the recorded content sent from the comment management unit 28, and when a comment exceeding a predetermined number of times is detected, a chapter is added to the corresponding portion of the recorded content. Set. The chapter edit processing unit 29 repeats the above processing until the processing for all the comment information is completed. In the above, the chapter is set when the number of comments is a certain number or more. However, the present invention is not limited to this, and the chapter may be set in a portion where a predetermined number of comments are written. . Therefore, chapters can be automatically set based on comments written by an unspecified number of users.

  In the case of the second method, when the user sets one or a plurality of keywords and the chapter edit processing unit 29 detects a comment including the set keyword, the content in which the comment including the keyword is written Set the chapter in the part and edit it.

  Recording start / end time and channel name information are recorded in the recorded content recorded on the hard disk (cartridge 100). Further, as described above, a comment posted to a comment accumulation server (not shown) includes a posting date and a channel name corresponding to the comment. Therefore, when the comment management unit 28 performs processing for acquiring and storing the comments stored in the comment storage server during the recording of the content, the content management unit 28 records the desired content on the hard disk. A comment group posted to the content storage server is received from the content storage server in real time for the channel broadcasting the content being recorded, and stored.

  In addition, when the comment management unit 28 acquires and stores comments stored in the comment storage server after recording the content, a comment group posted between the recording start time and the end time is posted from the comment storage server. Acquire and save with time information.

  As described above, since the comment group corresponding to the recorded content can be acquired during or after the recording with respect to the desired recorded content, when performing the chapter editing process, the chapter editing processing unit 29 is stored in the hard disk. Of the comment group, the comments related to the recorded content that is subject to chapter editing are obtained via the comment management unit 28. For example, the number of comments is counted every minute, and the chapter is set when the number is equal to or greater than a certain number. To do. That is, it is possible to set a chapter in the recorded content portion according to the time when the number of comments written reaches a predetermined number.

  Processing for detecting a comment including a set keyword and setting a chapter can be performed in the same manner, and a chapter can be set in a portion of the recorded content corresponding to the time when the comment in which the keyword is detected is written. With this configuration, when the recorded content is, for example, a movie, the scene (such as a last scene or a mountain scene) corresponding to the point in time when the number of related comments regarding the recorded movie is written above or below a certain number is automatically set. You can set chapter settings. Therefore, the user can directly call the scene (scene) at the time of reproduction and can reproduce from the scene.

  FIG. 7 is a flowchart showing the procedure of the chapter editing process using the first method described above. When the chapter editing process 29 is started, the chapter editing processing unit 29 acquires comment information related to the recorded content stored in the cartridge 100 via the comment management unit 28 (step S101). Next, the chapter edit processing unit 29 starts analysis processing of the acquired comment information (step S102). In the process of step S103, the chapter edit processing unit 29 determines whether there is a comment exceeding the predetermined number of times or less than the predetermined number of times.

  When a comment that exceeds the predetermined number of times or less than the predetermined number of times is detected, the chapter editing processing unit 29 sets a chapter in the corresponding part of the recorded content (step S104), and proceeds to the determination process of step S105. On the other hand, when the determination process in step S103 does not detect a comment that exceeds the predetermined number of times or less than the predetermined number, the process proceeds to the determination process in step S105.

  In the determination processing in step S105, the chapter editing processing unit 29 determines whether or not the processing for all the comment information has been completed. If the process for all of the comment information has not been completed, the process returns to step S102 and the above process is repeated. When the process for all of the comment information is completed, the chapter editing process is completed, and the chapter editing processing unit 29 stores the chapter set for the recorded content in the cartridge 100. When the recorded content recorded by the user on the cartridge 100 is played back, the recording / playback control unit 25 outputs the chapter stored in the cartridge 100 via the video / audio output unit 27 and displays it on the screen.

  In the case of the second method, the chapter editing processing unit 29 analyzes the comment information regarding the recorded content sent from the comment management unit 28, and a comment including the keyword is determined according to one or more keywords set in advance by the user. Set chapters on written content. The chapter edit processing unit 29 repeats the above processing until the processing for all the comment information is completed. Therefore, by setting a desired keyword in advance, the user can set a chapter based on the keyword desired by the user for the recorded content.

  FIG. 8 is a flowchart showing the procedure of the chapter editing process using the second method based on the set keyword. When the chapter edit processing unit 29 starts the chapter edit processing, the chapter edit processing unit 29 acquires comment information regarding the recorded content stored in the cartridge 100 via the comment management unit 28 (step S201). Next, the chapter edit processing unit 29 starts an analysis process for the acquired comment information (step S202). In step S203, the chapter edit processing unit 29 determines whether there is a comment including the set keyword.

  When a comment including the set keyword is detected, the chapter editing processing unit 29 sets a chapter in the corresponding part of the recorded content (step S204), and proceeds to the determination process of step S205. On the other hand, when a comment including a comment including the keyword set in the determination process in step S203 is not detected, the process proceeds to a determination process in step S205.

  In the determination processing in step S205, the chapter editing processing unit 29 determines whether or not the processing for all of the comment information has been completed. If the processing for all of the comment information has not been completed, the processing returns to step S202 and the above processing is repeated. When the process for all of the comment information is completed, the chapter editing process is completed, and the chapter editing processing unit 29 stores the chapter set for the recorded content in the cartridge 100. When the recorded content recorded by the user on the cartridge 100 is played back, the recording / playback control unit 25 outputs the chapter stored in the cartridge 100 via the video / audio output unit 27 and displays it on the screen.

  As described above, in the recording / reproducing apparatus according to the present invention, in the recording / reproducing apparatus that uses a cartridge type hard disk standardized in accordance with the iVDR standard as a recording medium, an unspecified number obtained from the social network. Since various comment information recorded by people can be used to perform chapter editing on the recorded content, the user can perform chapter editing on the recorded content without performing various chapter editing operations.

  Devices such as a cartridge conforming to the iVDR standard and a recording / reproducing apparatus employing the cartridge are highly compatible. In particular, in the recording and playback of digital broadcasts, it is compatible with content protection technology (SAFIA: Security Architecture for Intelligent Attachment device) that features device compatibility, and is highly convenient for compatibility with digital TV devices. ing.

  According to this device, if the content recorded on the cartridge is a broadcast receiving device compliant with iVDR, the content recorded on the cartridge can be reproduced even if the content is replaced with a broadcast receiving device of another manufacturer.

  Editing and giving of chapters to content is performed in accordance with the standard of a medium for recording content. However, since a recording / reproducing device conforming to the iVDR standard is highly compatible, the recording / reproducing device does not support the chapter editing function. Even so, if the recording / playback apparatus has a chapter playback function, the cartridge 100 storing the chapter information can be attached to the recording / playback apparatus and the recorded content can be played back in chapters.
