Abstract
The present invention relates to an interactive medium and a method for managing additional contents synchronously outputted with audio/video (A/V) data in an interactive digital versatile disk (I-DVD). A player in which an interactive disk is seated accesses a server providing the additional contents of the A/V data recorded on the interactive disk before the interactive disk is reproduced, and receives updated information of the additional contents from the server. The player refers to the received updated information and determines whether an arbitrary file contained in an additional content list associated with the A/V data has been updated. The player makes a request for an original file contained in the list or an updated file designated in the updated information, and receives the requested original or updated file. Therefore, the player can always receive additional contents containing the updated file. According to this operation, the server enables the additional contents to be conveniently updated.
