Abstract: A method for connecting a media player to a remote server is provided. The method comprises processing a request for connecting to an remote server while reproducing data recorded on an enhanced navigation medium, processing connection information recorded on the enhanced navigation medium to determine whether connection to the remote server is permitted, and requesting connection to the remote server, if connection to the remote server is permitted in accordance with the connection information.

Abstract: 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.

Abstract: In accordance with one or more embodiments, a method and system of managing animation data and related control data for recording on an enhanced navigation medium is provided. The method comprises constructing animation data comprising first image data into a first graphic MNG file in chunk data format, wherein the first graphic file comprises a first header portion, a second end portion, first control data and a frame containing additional data; and recording the first graphic file on an enhanced navigation medium.

Abstract: 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.

Abstract: In accordance with one or more embodiments, a method for setting a playback environment for an ENAV recording medium comprises determining availability of additional contents associated with audio/video (A/V) data recorded on the ENAV recording medium, based on data recorded on the ENAV recording medium; loading the additional contents in a temporary storage area; and reproducing the A/V data and the additional contents loaded in the temporary storage area according to the data.

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: 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.

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.

Abstract: 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.

Abstract: 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.

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.
