Abstract
In reproduction of a predetermined title recorded on an optical disk, when multiangle video images are recorded on the optical disk, an angle mark having a form of a camera is turned on. During reproduction of this title, when reproduction reaches a multiangle video image recorded portion, the angle mark flashes so that a viewer or user of the video can be notified of a state in which video reproduction at an angle different from that of the currently reproduced video image is possible.
