METHOD FOR REPRODUCING AV DATA IN ENAV MODE, A DEVICE THEREFOR, AND AN INFORMATION STORAGE MEDIUM THEREFOR, SPECIALLY IN CONNECTION WITH PRELOADING ENAV DATA NECESSARY FOR SEAMLESS REPRODUCTION 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 guarantee the seamless reproduction of AV data corresponding to an ENAV application by performing a preload process, and to clearly suggest the preload process, thereby supplying compatibility of the preload process. CONSTITUTION: A parser reads a loading information file loaded in an ENAV buffer(1201), and verifies whether the read loading information file is available(1202). An interpreter interprets the loading information file to send position information on an ENAV file to an interface handler, so that the interface handler can transmit the position information to a buffer manager(1203). The ENAV buffer reads a necessary ENAV file from a disk or a network(1204). The buffer manager confirms that a preload process is terminated by perceiving a state of the ENAV buffer, and generates a preload trigger to the interface handler(1205). The interface handler converts the preload trigger into a preload complete event, and transmits the event to the interpreter. The interpreter receives a verified initial file to interpret the file(1206).
