Abstract: Disclosed herein are a method for reproducing contents information in an interactive optical disc device and a method for providing contents information in a contents provider server. The interactive optical disc device is connected with the contents provider server via the Internet to receive a variety of contents information provided from the contents provider server. When the sending of the contents information from the contents provider server to the interactive optical disc device is suspended or delayed due to a network connection loss on the Internet or an insufficient storage capacity of a buffer memory in the interactive optical disc device, contents information re-sent from the contents provider server and a data stream read from an interactive DVD are re-synchronized and reproduced. Therefore, a user of the interactive optical disc device can normally watch more various contents information.

Abstract: A method for controlling playback of data recorded on an enhanced navigation medium is provided. The method comprises initializing at least a first playback engine of an enhanced navigation device, when an enhanced navigation mode is selected; entering a first playback state for at least the first playback engine, when an enhanced navigation engine preloads navigation information; and controlling media playback operations, in response to user interaction with a user interface of the enhanced navigation device; wherein the enhanced navigation engine controls a plurality of playback states based on the user interaction with a plurality of user interfaces of the enhanced navigation device.

Abstract: 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.

Abstract: A method of playing interactive content information using a content disk player is provided. The method comprises retrieving playback time information of first content information recorded on a recording medium playable in a content disk player; transmitting the playback time information to a content server in communication with the content disk player via a communication network; receiving second content information corresponding to the first content information from the content server; and playing back the second content information along with the first content information, based on said playback time information.

Abstract: A method of reproducing information stored on a data recording medium accessible via a communication network comprises loading first information stored on the data recording medium for reproduction, determining if second information associated with the first information is available through the communication network; and synchronizing the reproduction of the first information and the second information with respect to a timing information embedded in the second information. The timing information is relative to a play start time associated with the first information.

Abstract: In accordance with one or more embodiments of the invention, a reproduction engine for reproducing A/V data stored on an interactive DVD comprises a navigator connected to a temporary data storage unit for loading A/V data from the interactive DVD into a first section of the temporary data storage unit, and for loading enhanced data associated with the A/V data into a second section of the temporary data storage unit; a decoder for decoding the A/V data and the enhanced data loaded into the temporary data storage unit; and a presentation engine for reproducing the decoded A/V data and the enhanced data in accordance with control information stored on the interactive DVD.
