Abstract
When an instruction is given to perform a playback operation, for example, a fast-forward operation, at a speed greater than normal, a system controller obtains playback data (VOBU) corresponding to a current playback position, and the video images and the subtitles are played back by using this VOBU, and are displayed. The system controller then moves the playback position by a predetermined amount of movement (for example, three VOBUs) without performing the fast playback operation. The fast playback operation is then performed by using the VOBU corresponding to the moved playback position. In this manner, the fast playback operation and the movement operation are alternately repeated to display the video images and the subtitles.
