Description

  The present invention relates to a recording medium reproducing apparatus, and more particularly to a recording medium reproducing apparatus having an edit mode for deleting a desired scene from a predetermined title recorded on a recording medium.

  2. Description of the Related Art In recent years, as a device for recording and reproducing video and audio processed in a video device such as a television, a digital video information processing device such as a DVD (Digital Versatile Disk) recorder or an HDD (Hard Disk Drive) recorder is used. It has become widespread. One of the functions of these digital video information processing apparatuses is an editing function for deleting a scene having content (video information). By using this editing function, the user can delete a part of scenes (for example, a CM scene) from the recorded content. Examples of the editing method include a method in which the user designates the beginning and end of the scene to be deleted, and only the designated portion of the scene is deleted. However, when there are a relatively large number of scenes to be deleted, such as a CM cut, there is a problem that it takes much time and effort to manually designate and delete the beginning and end of each scene. In order to solve the above problems and improve the convenience of the editing function, various proposals have been conventionally made.

  In relation to the above problem, Patent Document 1 discloses a recording / reproducing apparatus having means for recording and managing various edited contents as information different from the actual data to be edited with respect to recorded data (content). . The recording / reproducing apparatus of Patent Document 1 is a multimedia information recording / reproducing apparatus that records and reproduces data obtained by converting information such as video and audio into an electric signal such as digital or analog on a randomly accessible medium. The recorded data has means for recording and managing various editing contents as information different from the actual data to be edited. In addition, a cut function for deleting a part of information to be reproduced along a time axis such as a moving image or sound is provided. In the cut function, the deletion start point and end point can be set by the same key operation. It is also possible to set multiple cut ranges

  According to the above-described invention of Patent Document 1, the user can perform various edits while safely storing the recorded data without changing the data, and can easily perform the edit again. This operation can be performed while visually recognizing the state of the reproduced data.

  In relation to the resume function, Patent Document 2 discloses an editing / playback apparatus that can edit recorded data without changing the recorded data itself and can play back the edited recorded data. The editing / playback apparatus of Patent Document 2 includes an editing unit that creates editing information for recording data stored in a recording medium, a storage unit that stores the editing information, and an execution unit that plays back the recording data according to the editing information. It is equipped with. The editing means is used to create editing information according to the desired editing contents without directly editing the original recording data. Then, using the execution means, the recording data is called according to the editing information, processed according to the editing content, and the processed recording data is reproduced. Since the edited recording data is not stored, the original recording data is not changed.

  According to the above-described invention of Patent Document 2, since editing information is created, managed, and executed by internal processing, there is no need to change the original recording data. Therefore, it is possible to edit as many times as the original recording data remains, and it is not necessary to store the edited recording data, so that a large amount of recording data can be stored without consuming free space on the recording medium. Is possible.

  The conventional scene editing functions shown in the above documents will be described with reference to flowcharts and screen views. The scene editing function is a function for performing editing processing such as scene deletion, and is a function for deleting an unnecessary scene such as a CM from a certain content (video information), for example. The data recording the scene to be deleted is deleted, and the scene is edited by combining the data before and after the deletion.

  FIG. 9 is a flowchart showing a process flow of a conventional scene editing process. FIG. 10 is a block diagram showing a change in data when executing a scene deletion process in the conventional scene editing process. In FIG. 10A, the range indicated by the arrow α is the length of the content data before scene deletion. As shown in FIG. 10B from this state, when a part of the data (the range indicated by the arrow β) is designated as a deletion target, the data in the designated range is erased, resulting in FIG. (C) is data of a length indicated by an arrow γ (where γ = α−β).

  11 to 13 are screen views showing an example of a scene editing screen for performing a conventional scene editing process. Processing related to the screen transition from FIG. 11 to FIG. 13 will be described using the flowchart of FIG. On the video display screen A1, a playback video of the content to be edited is displayed. At the beginning of the process, the playback position cursor B1 indicating the current playback position is set to be positioned at the beginning of the content (S210). As the playback of the content proceeds, the playback position cursor B1 moves to the right within the range of the time scale B2, and the state shown in FIG. 11 is obtained. Note that the playback position cursor B1 can be moved in the right direction or the left direction at a double speed by instructing fast-forwarding or rewinding to the content being played back.

  When the deletion start position designation button C1 shown in FIG. 11 is pressed (Start Point in S220) during the reproduction of the content or during the pause of reproduction (for example, the button is selected by the ten o'clock key of the remote controller, and the determination button of the remote controller is When pressed, the current position of the playback position cursor B1 is set as the start point of the deletion scene (deletion start position D1 in FIG. 12) (S230). In each scene editing process screen, when the scene deletion cancel button C2 is pressed (Return in S220, S240, and S260), the deletion start position D1 can be discarded and the scene editing process can be forcibly terminated. It is.

  In FIG. 11, when the deletion start position designation button C1 is pressed, the scene editing screen changes to the state shown in FIG. In FIG. 12, a deletion start position cancel button C3 and a deletion end position designation button C4 can be newly selected. When the deletion start position cancel button C3 is pressed (Start Point Cancel in S240), the deletion start position D1 is canceled (erased) (S241). When the deletion start position D1 is deleted, the scene selection screen again transitions to the state (S220) shown in FIG. Conversely, when the deletion end position designation button C4 is pressed (End Point in S240), the current position of the reproduction position cursor B1 is set as the end point (deletion end position) of the deletion scene (S250).

When the deletion end position designation button C4 is pressed in FIG. 12, the scene editing screen changes to the state shown in FIG. In FIG. 13, the determined deletion target range β1 is displayed, and a scene deletion execution button C5 and a deletion end position cancel button C6 can be newly selected. When the deletion end position cancel button C6 is pressed (End Delete in S260), the deletion end position is canceled (erased). If deleted, the scene selection screen again transitions to the state (S240) shown in FIG. Conversely, when the scene deletion execution button C5 is pressed (Updat in S260), the scene in the deletion target range β1 is deleted and the content is updated (updated) (S270). At this time, the actual data is not updated, and the scene deletion can be virtually performed by excluding the deletion target range β1 from the reproduction target by the address information operation.

  However, in the conventional storage / playback devices represented by Patent Document 1 and Patent Document 2, when a scene is deleted in editing work, the playback position is always returned to the top position of the content. For this reason, when deleting scenes continuously, it is necessary to fast-forward the video to the beginning of the scene to be deleted again after deleting the scene, and there is a problem that it takes time and effort for the user. However, Patent Document 1 and Patent Document 2 do not disclose or suggest a technique for reducing the time required for the user to delete a scene, that is, a technique for reducing the amount of work required for deleting a scene.

  Further, in the storage / reproduction devices disclosed in Patent Document 1 and Patent Document 2, the actual data (video data) recorded on the recording medium is not changed, and management information (address information) of the actual data is not changed. Etc.) are used to virtually edit the scene. For this reason, for example, even if a scene is deleted, the actual data to be deleted still remains on the recording medium. That is, there is a problem that when the actual data is deleted by the editing process and the free space of the storage medium is to be secured, a sufficient role cannot be played.

  The present invention has been made to solve the above problems, and its purpose is to reduce the number of processes related to scene deletion work on actual data and shorten the editing time, thereby improving the convenience of the user. An object of the present invention is to provide an improved recording medium reproducing apparatus.

In the video information editing means, video information updating means for updating the video information by deleting data corresponding to the deletion target range from the recording medium;
A recording medium playback device comprising:
In the deletion target range setting means, after specifying one deletion target range, by continuing execution of the deletion target range setting means without executing the video information update means for the video information, a plurality of deletion target range setting means The deletion target range can be set simultaneously;
It is characterized by.

  According to this configuration, when editing the content (video information) recorded on the hard disk (recording medium) (for example, deleting a part of the scene), the start point of the deleted scene (deletion target range) The range of the deletion scene is set by specifying the end point. The set deletion scene data is physically erased from the hard disk by receiving a deletion execution command. At this time, immediately after the user designates the deletion scene, the user can continuously select a plurality of deletion scenes without updating the contents (effective execution of the deletion execution command).

In order to achieve the above object, the video information processing apparatus of the present invention
In the video information update means, when a plurality of the deletion target ranges are set, deleting a plurality of the deletion target ranges from the recording medium at a time,
In the video information update means, the video information from which a plurality of ranges have been deleted by the batch deletion process is connected in time order to form one video information;
It is characterized by.

According to this configuration
In the content editing process, when the user specifies multiple deletion scenes at the same time, when the user updates the content (the execution of the deletion execution command), the selected multiple deletion scenes are deleted at once. The In addition, content in which a plurality of blank portions are generated is updated as content with new contents by connecting scenes before and after each deleted scene.

  According to the first configuration of the present invention, when the user edits the content recorded on the hard disk, immediately after selecting the scene to be deleted, the content is updated as before (the deletion execution command is effective). It is possible to continue to select a deletion scene without performing the above. This eliminates the need for a series of operations such as updating the content each time the selection of the deletion scene is performed once and setting the deletion scene by playing again from the beginning of the content. Thus, since the amount of work for the user is reduced, convenience for the user is improved.

  According to the second configuration of the present invention, after the user simultaneously specifies a plurality of deletion scenes in the content editing process, the user updates the content (the deletion execution command is activated), thereby selecting the plurality of selected scenes. The deleted scenes are deleted all at once, and the contents are updated with the remaining scenes. For this reason, it is not necessary for the user to individually issue a deletion execution command to a plurality of selected deletion scenes, and the amount of work for the user is reduced, so that convenience for the user is improved.

  An embodiment of the present invention will be described below with reference to the drawings.
