DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an optical disk reproducing apparatus for reproducing an optical disk such as a DVD (digital video disk), and more particularly to an optical disk reproducing apparatus for selecting and reproducing an angle of a multi-angle video recorded on an optical disk. .

[0002]

2. Description of the Related Art An optical disc such as a DVD includes a multi-angle video in which video shot from a plurality of angles is recorded, and a viewer selects a desired angle to view a multi-angle video. Is available.

[0003] The prior art is disclosed, for example, in Japanese Patent Application Laid-Open No. 11-180.
As described in Japanese Patent No. 58, when displaying an image of an angle of a multi-angle image on a screen of a monitor device during reproduction of an optical disk on which a multi-angle image is recorded, a switch can be made at the top of the screen of the monitor device. Of the angle of the multi-angle video (angle during playback,
Unplayed angles and played angles) are displayed to prevent the viewer from overlooking unplayed images.

[0004]

However, according to the above-mentioned prior art, during playback of an optical disc on which a multi-angle video is recorded, a viewer can watch the reproduction status of the angle of the multi-angle video displayed on the screen of the monitor device. Thus, it was possible to know whether the angle was already played or an angle that was not played back, but the angle of the selected multi-angle video and the time at which the angle was selected were stored, At the time when the angle of the multi-angle video is selected, the optical disk is not reproduced by switching to the video of the selected multi-angle video. Therefore, when the viewer again plays the optical disk on which the multi-angle video is recorded and views the video, he / she operates the keys of a remote controller or the like to select the angle of the multi-angle video and views the video before. There has been a problem that it is not possible to view an image of the same multi-angle image as at the time.

[0005] The present invention has been made in view of the above points, and when reproducing an optical disc on which a multi-angle video is recorded, when reproducing the multi-angle video, the video being reproduced is a multi-angle video. Displayed on the screen of the monitor device, the angle of the multi-angle video selected by the viewer is stored together with the time at which the angle was selected, and again, when playing back the optical disk to view the video,
At the time when the angle of the multi-angle video is selected, it is possible to switch to the video of the selected angle of the multi-angle video and play the optical disc to view the same angle of the multi-angle video as previously viewed. To make it possible.

Also, at the time of reproducing the multi-angle video, whether or not the angle of the multi-angle video being reproduced is stored in the memory is displayed on the screen of the monitor device, and the angle of the multi-angle video stored in the memory is displayed. Can be changed to another angle, and the angle of the multi-angle video stored in the memory can be erased.

[0007]

In order to achieve the above object, according to the present invention, in an optical disc reproducing apparatus for reproducing an optical disc on which a multi-angle video shot from a plurality of angles is recorded, an angle of the multi-angle video is selected. Angle selection means to perform, the time at which the angle of the multi-angle video is selected, time-measuring means to time as the elapsed time from the start of reproduction of the multi-angle video, and the angle of the multi-angle video selected by the angle selection means, Storage means for storing the angle together with the selected time, and angle erasing means for erasing the angle of the multi-angle video stored in the storage means, wherein the angle of the multi-angle video is selected during reproduction of the optical disc. ANGLE of the selected multi-angle video Is stored in the storage unit together with the time when the angle is selected, and when the angle of the multi-angle video is stored in the storage unit, the angle is stored in the storage unit at the time when the angle of the multi-angle video is selected. The optical disk is played back by switching to the angle image of the multi-angle image being played, and when another angle of the multi-angle image being played is selected, the angle and angle of the multi-angle image stored in the storage means are selected. The time is rewritten to another angle of the selected multi-angle video and a time at which the other angle is selected and stored in the storage means, and the angle of the multi-angle video stored in the storage means is rewritten. During reproduction of the video, the angle of the multi-angle video being reproduced stored in the storage means is deleted. To make it possible.

When the video being reproduced is a multi-angle video, a first display control means for displaying a character or an icon indicating that the video is a multi-angle video at a predetermined position on a screen of a monitor device, First display control means capable of selecting display or non-display, and whether or not the angle of the multi-angle video being reproduced is stored in the storage means is displayed at a predetermined position on the screen of the monitor device. A second display control means, which is capable of selecting display or non-display, wherein whether or not the video being reproduced is a multi-angle video during reproduction of the optical disc; Is displayed on the screen of the monitor device, and during the reproduction of the multi-angle image, whether or not the angle of the multi-angle image is stored in the storage means is displayed on the screen of the monitor device. That.

By means of these means, when reproducing an optical disk on which a multi-angle video is recorded, when the multi-angle video is reproduced, the fact that the video being reproduced is a multi-angle video is displayed on the screen of the monitor device. The angle of the multi-angle video selected by the camera is stored together with the time at which the angle was selected, and when the optical disk is played back and the video is viewed again, the angle of the multi-angle video is selected at the time at which the angle of the multi-angle video is selected. The optical disk is reproduced while being switched to the angle video of the angle video, and the same angle video of the multi-angle video as viewed previously can be viewed.

When a multi-angle video is reproduced, whether or not the angle of the multi-angle video being reproduced is stored in a memory is displayed on a screen of a monitor device, and the angle of the multi-angle video stored in the memory is displayed. The angle can be changed to another angle, and the angle of the multi-angle video stored in the memory can be deleted.
