Description

  The present invention relates to a recording medium playback apparatus having an edit mode for deleting a desired scene from a predetermined title recorded on a recording medium.

  In recent years, optical disc devices such as DVDs and hard disk recorders have been used for recording television broadcast content at home. One of the functions of these devices is an editing function for deleting a certain scene of content. Using this editing function, the user can delete scenes such as CMs from the recorded content. Various proposals have been made to improve the usability of such editing functions.

  For example, Japanese Patent Laid-Open No. 2004-228688 discloses a means for adding entry information indicating a position edited by a user instruction in a new reproduction order to new management information, and the new management information to which the entry information is added is a digital recording medium. An editing device including a recording means for recording in the above is disclosed.

  For example, Patent Document 2 discloses a recording / reproducing apparatus having means for recording and managing various editing contents as information different from the actual data to be edited.

Further, for example, Patent Document 3 discloses a playback method of a removable medium that can reproduce information from a predetermined position even when information corresponding to the last position is deleted from the recording type removable medium.

  Conventionally, when a certain scene is deleted in editing work, the playback position returns to the top of the title. Therefore, when the scene is continuously deleted, the user has to fast-forward to the desired scene, which takes time and effort. However, in Patent Documents 1 to 3, there is no description of a technique for reducing the time required for the user to delete a scene, that is, a technique for reducing the trouble of deleting a scene.

  It is an object of the present invention to provide a recording medium playback apparatus with improved usability by shortening the time for scene deletion and shortening the editing time.

In order to achieve the above object, the present invention is a recording medium playback device having an edit mode for deleting a desired scene from a predetermined title recorded on a recording medium,
In the editing mode, when a scene has been deleted from the title in the past, a playback start position is set immediately after the previously deleted scene.

  According to this configuration, after the scene is deleted, playback is continued from that position.

  In the editing mode, when the scene has not been deleted from the title in the past, the top of the title is set as the reproduction start position.

  According to this configuration, when a scene is deleted for the first time, the title is played from the beginning.

When the present invention is embodied, a recording medium playback device having an editing mode for deleting a desired scene from a predetermined title recorded on a recording medium,
In the editing mode,
If the scene has been deleted from the title in the past, the playback start position is immediately after the previously deleted scene,
If the scene has not been deleted from the title in the past, the beginning of the title is the playback start position,
Accepts an input command to set the current playback position as the scene deletion start position,
Accepts an input command to set the current playback position as the scene deletion end position,
An input command for authenticating the start position and the end position is received.

  According to the present invention, when a scene has been deleted in the past from the title to be edited, it is not necessary to search from the beginning of the title every time the scene is deleted by setting the playback start position immediately after the previously deleted scene. Therefore, the time for scene deletion can be shortened to shorten the editing time. This improves the usability of the device.

  Further, when a scene has not been deleted from the title to be edited in the past, it is possible to deal with the case where the scene is deleted for the first time by setting the beginning of the title as the reproduction start position.

  Hereinafter, a hard disk drive (HDD) integrated optical disk device will be described as an example of a recording medium playback device. FIG. 1 is a block diagram showing a configuration of an HDD-integrated optical disk device and its peripheral devices. The HDD-integrated optical disk device 10 is connected to a display device 11 such as a television and an external device 12 such as a video deck. The HDD integrated optical disk device 10 can be operated by a remote controller 13. Hereinafter, a DVD will be described as an example of the optical disk.

  The HDD-integrated optical disc apparatus 10 is based on an antenna 15 that receives a television broadcast signal, a tuner 16 that demodulates and digitizes the television broadcast signal received by the antenna 15, and image / audio data received from the tuner 16 in conformity with MPEG2 or the like. The image / audio compression / decompression unit 17 for decompressing and decoding the compressed image data reproduced by the HDD recording / reproducing unit 18 or the DVD recording / reproducing unit 19, and the compression received from the image / audio compression / decompression unit 17. The recorded image / audio data, the HDD recording / reproducing unit 18 for reproducing the recorded data, and the compressed image / audio data received from the image / audio compression / decompression unit 17 are recorded on the inserted DVD. , A DVD recording / reproducing unit 19 for reproducing data recorded on the DVD, and various setting values in one display device 11. An OSD (On Screen Display) unit 20 that can be set while being displayed on the screen, an image output unit 21 that converts an image signal from the OSD unit 20 into an analog signal, and outputs the analog signal to the display device 11. An audio output unit 22 that converts an audio signal into an analog signal and outputs it to a display device, a memory 23 such as a ROM or a RAM, a remote control receiver 24 that receives a signal from the remote controller 13, and an external I / O to which the external device 12 is connected F25 and a control unit 26 that controls each unit of the HDD-integrated optical disc apparatus 10 are provided.

  The control unit 26 also controls an edit mode when a desired scene is deleted from a predetermined title recorded on a DVD or HDD as a recording medium. The edit mode will be described below.

  FIG. 2 is a flowchart showing the recording operation of the HDD-integrated optical disc apparatus 10 in the edit mode. When the operation panel (not shown) of the remote controller 13 or the HDD-integrated optical disc apparatus 10 is operated by the user, the edit mode is selected and determined for a predetermined title, and then the scene deletion menu is selected and determined, the control unit 26 edits. The mode scene deletion menu is activated, and it is determined whether or not a scene has been deleted in the past from the title designated by the user in step S10. The scene deletion is to delete an unnecessary scene such as a CM from a certain title, which is one of editing functions. The deleted scene is simply played back when the edited title is played back, and the data itself is not deleted.

  If it is determined in step S10 that the scene has been deleted in the past, the process proceeds to step S11, where the reproduction start position is set immediately after the previously deleted scene. On the other hand, if it is determined in step S10 that no scene has been deleted in the past, the process proceeds to step S12, and the head of this title is set as the reproduction start position. Therefore, the designated title is played back immediately after the previously deleted scene during the second and subsequent scene deletion operations, and when the scene is deleted for the first time, playback is started from the beginning of the title.

  Then, when the reproduction is started from a predetermined position, the process proceeds to step S13, where the input command displayed on the display device 11 is accepted. The input command here is a command for designating the current playback position as the scene deletion start position. FIG. 3 shows an example of a screen for designating the scene deletion start position. The screen 30 is a title movie 31 to be played back, a time scale 32 representing the time of the title, a vertical line in the time scale 32, a playback position cursor 33 indicating the current playback location, and the user starts deleting It comprises a Start Point button 34 for designating a position and a Return button 35 for exiting the scene deletion menu.

  When the Start Point button 34 is selected and determined in step S13, the process proceeds to step S14, and the current playback position is stored in the memory 23 as the deletion start position. On the other hand, when the Return button 35 is selected and determined in step S13, the scene deletion menu is terminated.

  When the process proceeds from step S14 to step S15, the input command newly displayed on the display device 11 is accepted. The input command here is a command for designating the current playback position as the scene deletion end position. FIG. 4 shows an example of a screen for designating the scene deletion end position. On the screen 40, instead of the Start Point button 34 on the screen 30, a Start Point Cancel button 41 for discarding the deletion start position designated by the user and an End Point button 42 for designating the deletion end position by the user are displayed.

  When the End Point button 42 is selected and determined in step S15, the process proceeds to step S16, and the current reproduction position is stored in the memory 23 as the deletion end position. On the other hand, if the Start Point Cancel button 41 is selected and determined in step S15, it is determined that the deletion start position has been specified incorrectly, and the process proceeds to step S17 to discard the deletion start position stored in the memory 23. Return to S13. If the Return button 35 is selected and determined in step S15, the scene deletion menu is terminated.

  When the process proceeds from step S16 to step S18, the input command newly displayed on the display device 11 is accepted. The input command here is a command for authenticating the start position and end position of scene deletion. FIG. 5 shows an example of a screen for authenticating scene deletion. On the screen 50, instead of the Start Point Cancel button 41 and the End Point button 42 on the screen 40, an End Delete button 51 for discarding the deletion end position designated by the user, and the start position and end position designated by the user are determined. An Update button 52 is displayed. In addition, a scene deletion target range 53 is displayed in the time scale 32.

  When the Update button 52 is selected and determined in step S18, the process proceeds to step S19, and the control information related to editing is updated to determine the scene deletion start position and end position stored in the memory 23. After updating the control information, the process may return to step S10, or the scene deletion menu may be terminated. On the other hand, if the End Delete button 51 is selected and determined in step S18, it is determined that the deletion end position has been specified in error, the process proceeds to step S20, and the deletion end position stored in the memory 23 is discarded, and step S15. Return to. If the Return button 35 is selected and determined in step S18, the scene deletion menu is terminated.

  In the above scene deletion processing, when the recording medium is a DVD, the title and address may be stored as the scene deletion start position and end position. When the recording medium is an HDD, the title and time may be stored as the scene deletion start position and end position.

  Next, as a specific example of the scene deletion described above, a procedure for deleting a CM by editing a certain unedited title recorded on a DVD will be described. First, the user selects and determines a desired title of the DVD, subsequently selects and determines an edit mode, and further selects and determines a scene deletion menu. Then, the screen as shown in FIG. 3 is displayed, and the moving image 31 is reproduced from the beginning of the title. Therefore, when the CM to be deleted is reproduced while viewing the moving image 31, the Start Point button 34 is selected and determined. As a result, the title and address are stored in the memory 23 as the scene deletion start position. Then, a screen as shown in FIG. 4 is displayed, and when the CM ends, the End Point button 42 is selected and determined. Thus, the title and address are stored in the memory 23 as the scene deletion end position. Then, a screen as shown in FIG. 5 is displayed, and the Update button 52 is selected and determined. Thereby, the control information is updated and a scene to be deleted is registered. Then, the screen returns to the screen as shown in FIG. 3, and the playback continues immediately after the scene deletion end position. Therefore, if the next CM is played back, the scene deletion may be performed as described above. During playback of the moving image 31, operations related to playback such as fast forward and rewind can be performed.

  If the scene has been deleted in the past from the title to be edited as in the above embodiment, it is necessary to search from the beginning of the title every time the scene is deleted by setting the playback start position immediately after the previously deleted scene. Therefore, the time for scene deletion can be shortened and the editing time can be shortened. This improves the usability of the device.

  The present invention can be used for reproducing apparatuses for various recording media having an editing function, such as an optical disk apparatus such as a DVD, a hard disk recorder, and an optical disk apparatus integrated with a hard disk drive.
