The present invention provides an extensible disc player that is upgradeable to play new content types. The player's capability can be extended by downloading an appropriate decoder from a web server via the Internet. In this way, the player can play back contents that it does not originally support. If the content type is unknown, the player will check whether the disc contains a URL for linking to a web site containing an appropriate decoder. If the disc contains the URL, the player will access the web site to download the appropriate decoder. In a similar manner, the capability of a recorder can also be expanded by downloading appropriate encoders from the Internet.

The present invention provides a WebDVD player to link legacy DVD discs to related web sites and to play normal WebDVD discs. The player includes a database containing a URL list of popular DVD content providers. After the disc is loaded into the player, the player reads the provider unique identification (PVR ID) and uses the PVR ID to find URL of associated content provider from URL list. URL of content provider is indexed to a table containing a list of some popular title identifications (Title IDs) of discs, location of Title ID on the disc, method of deriving Title ID, and URL of a related web site. The player then attempts to derive the Title ID of the disc according to the method in the table and compares the derived Title ID with the data in the Title ID column of the table to find the corresponding URL for locating the web pages of the content provider.

An optical disc player includes a detecting module and a creating module. The detecting module is used to detect whether to meet a branch point or an interruption point or a pause point; and the creating module is used to create a corresponding bookmark as a navigation for the subsequent broadcast to record the relevant information of a branch point or an interruption point or a pause point when meeting the branch point or the interruption point or the pause point. The playing method of the player includes: detecting whether to meet a branch point or an interruption point or a pause point, creating a corresponding bookmark as a navigation for the subsequent broadcast to record the relevant information of the branch point or the interruption point or the pause point when to meet the branch point or the interruption point or the pause point.

The present invention relates to a communication and/or reproducing device (20) able to read a data carrier (22) and a remote unit (10) comprising additional data (11) for the data carrier (22). The recording and/or reproducing device (20) and the remote unit (10) communicate via a network (30). The remote unit (10) is able to retrieve data carrier properties (23) from the data carrier (22) inserted in the recording and/or reproducing device (20), and to authenticate said data carrier (22) by comparing said properties (23) with the ones of a corresponding data carrier legally produced by a provider, before sending the additional data (11) to said recording and/or reproducing device (20).
摘要:
The present invention provides an optical disc with a generic logical format having a data structure that is defined independent of the content type (i.e., the data type and medium encoding scheme) and the physical medium. In accordance with one embodiment of the invention, a data storage medium is provided for storing data for access by a data processing system. The data storage medium comprises a data structure stored in the medium for describing different data contents stored therein. The data structure includes at least one content object containing data contents, an object definition file associated with the object for describing the object, and an index file including a table of contents having a reference to the object. The generic logical format of the invention can be easily adapted to any new content types without the need to define a complete new format.
