DATA STORAGE MEDIA STORING CONTROL DATA FOR CONTROLLING BUFFERING STATE OF MARKUP DOCUMENT, AND SYSTEM AND METHOD FOR REGENERATING SAME DATA STORAGE MEDIA

摘要

PURPOSE: A data storage media, and its regenerating system and method are provided to properly present a markup document by controlling a buffering state of the markup document though some of a pre-load target file is not completely pre-loaded. CONSTITUTION: The method comprises several steps. A markup document is buffered in order to pre-load the markup document. Then, in response to a report signal, a buffering state signal of the markup document is output. Accordingly, in a case that AV data stored at a DVD is regenerated and the AD data and its related markup documents are displayed via a markup document, the buffering state of the markup document is checked. So when the markup document is not buffered because a disc is physically damaged or a network is not connected, a substitute markup document is used or a natural document pass-over operation is performed.
