APPARATUS AND METHOD FOR FAST FORWARD AND BACKWARD PLAYING IN JPEG2000 BASED DIGITAL CINEMA SYSTEM

摘要

PURPOSE: A content high speed playback apparatus in a digital cinema system and method thereof are provided to offer content high speed playback method by using video stream which is hierarchically encoded. CONSTITUTION: In case outputted video steam is able to be reproduced in selected N-speed, a control unit(230) outputs the video stream of a higher resolution layer by decoding the video stream. The control unit repeatedly determines playback states. The control unit decodes the video stream until a layer which the video stream is reproduced in the selected N-speed.
