METHOD FOR REPRODUCING AV DATA IN ENAV MODE, A DEVICE THEREFOR, AND AN INFORMATION STORAGE MEDIUM THEREFOR, SPECIFICALLY IN REFERENCE TO PRELOADING ENAV DATA IN A BUFFER, AND REPRODUCING THE PRELOADED ENAV DATA

摘要

PURPOSE: A method for reproducing AV data in ENAV(Enhanced Navigation) mode, a device therefor, and an information storage medium therefor are provided to preload an ENAV file in a buffer disposed in an ENAV engine, and to interpret the preloaded ENAV file, so that the ENAV engine can guarantee a seamless reproduction of AV data in an ENAV mode. CONSTITUTION: A reader(1) controls an optical pickup, and reads AV data and ENAV data from a disk(100). An ENAV engine(3) interprets a markup language and a script language to present an ENAV file read by the reader(1). The ENAV engine(3) functions as a markup document viewer, and reads the ENAV data by accessing the Internet. An AV reproduction engine(2) decodes a selected video title in an ENAV mode, and transmits a decoded AV data stream to the ENAV engine(3). The ENAV engine(3) interprets a markup document to blend the markup document with the AV data stream, and outputs the blended document to a TV.
