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.

System and method for reproducing information stored on a data recording medium in an interactive networked environment

The present invention relates to an interactive disk reproducing method using a network. The present method downloads various content-related information and the latest contents associated with A/V data pre-recorded on a placed interactive disk from a remote content-providing server connected through a network before reproduction of the placed interactive disk, and makes presentation of video or audio reproduced from the interactive disk along with contents already-received from the server while synchronizing presentation time of the A/V data and the contents with reference to the downloaded content-related information.

Method of reproducing an interactive disk through a network

The present invention relates to an interactive disk reproducing method using a network. The present method downloads various content-related information associated with A/V data pre-recorded on a placed interactive disk from a remote content-providing server connected through a network, and makes presentation of video or audio reproduced from the interactive disk along with contents received from the server while synchronizing presentation time of the A/V data and the contents with reference to the downloaded content-related information.

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.
