ABSTRACT:
A method for managing recording and reproduction of a multi-dubbed audio stream. This method includes the steps of producing virtual play lists, the number of which corresponds to the number of dubbed audio streams desired by a user in association with the clip-unit main A/V stream, for reading and reproduction of the dubbed audio streams, and recording a common play item, for reading and reproduction of the clip-unit main A/V stream, in the virtual play lists, while recording distinct sub play items, for reading and reproduction of the dubbed audio streams associated therewith, in the virtual play lists, respectively. Management information for search and management of play lists for multiple dubbed audio streams is also recorded in the file structure of a rewritable storage medium such as BD-RE (Blu-Ray Disc Rewritable). Accordingly, it is possible to additionally record and manage multiple dubbed audio streams associated with one clip-unit main A/V stream, and to selectively reproduce diverse dubbed audio streams desired by the user.
