According to method of managing and reproducing additional audio files of an interactive optical disc, additional audio data associated with main video data of an optical disc such as an interactive DVD are recorded as a file of a prescribed format. File information about the additional audio data and buffering information thereabout recorded in the file of a prescribed format. An optical disc apparatus interprets the file information and buffering information and then carries out a series of operations storing and reading out and playing the additional audio data in a way suitable to the buffering area allocated within a buffer. Consequently, additional audio data of various contents are read out from the optical disc or provided by a content providing server connected through the Internet.

Method of managing and reproducing additional audio files of an interactive optical disc

A method of presenting auxiliary data for an interactive recording medium is disclosed. In an interactive recording medium reproducing apparatus that reproduces A/V data and contents data recorded on an interactive recording medium and contents data provided by a contents providing server, the contents data provided by the contents providing server is presented appropriately according to the attributes of the contents data by using attribute information for the contents data.

Method of presenting auxiliary data for an interactive recording medium

A method for authenticating an interactive optical disk, wherein first content is stored on the interactive optical disk for reproduction by a reproducing system, the method comprising: transmitting a first request to a content server to access second content from the content server based on enhanced navigation data recorded on the interactive optical disk; and authenticating identity of the interactive optical disk with the content server based on authentication data provided by the reproducing system, when the first request indicates that authentication is required.

Authentication system and method for an interactive optical disc

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.

Interactive medium and method for managing additional data thereof

A method and apparatus for synchronized reproduction of main contents recorded on an interactive recording medium and additional contents therefor is disclosed. The additional contents related to the main contents include time information for synchronizing the additional contents with a part of the main contents.

Method and apparatus for synchronous reproduction of main contents recorded on an interactive recording medium and additional contents therefor

An interactive DVD system for reproducing chatting data is provided. The Content disk player is connected to a content server via a communication network. The Content disk player system comprises means for forwarding a request to the content server to receive new chatting data associated with content for play-back by the Content disk player, wherein the request comprises a first LUT information; means for receiving the new chatting data and a second LUT information associated with the new chatting data; means for playing back the new chatting data in synchronization with content provided from a content source.

System and method for updating message data in an interactive disc player network

An interactive media player is provided. The player comprises a storage unit for storing a plurality of image sources read from a recording medium, each image source having a respective bit depth; a decoder for decoding the plurality of image sources, confirming the respective bit depths of the image sources, and determining whether or not the confirmed bit depths are to be converted to another bit depth; and a converter for converting at least one of the respective bit depths into another bit depth.
