METHOD FOR MANAGING AND REPRODUCING ADDITIONAL CONTENTS DATA OF A HIGH-DENSITY OPTICAL DISK, PARTICULARLY CONCERNED IN DISTINGUISHING VARIOUS ADDITIONAL CONTENTS DATA INTO SYNCHRONOUSLY AND ASYNCHRONOUSLY REPRODUCED ADDITIONAL CONTENTS DATA WITH REGARDS TO A/V DATA

摘要

PURPOSE: A method for managing and reproducing additional contents data of a high-density optical disk is provided to record and manage stream coding information on additional contents data within a clip information file for controlling a reproduction of main A/V data and the additional contents data, thereby effectively recording/managing synchronously and asynchronously reproduced additional contents data with regards to the main A/V data. CONSTITUTION: Within a clip information file associated with a clip file where a main A/V stream and an ENAV stream are recorded, program information is included. The program information includes stream packet IDs and stream coding information. In case of a packet ID corresponding to the ENAV stream among the stream packet IDs, an intrinsic packet ID distinguished from the main A/V data is additionally recorded in 16-bit recording size.
