Abstract

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.

Claims

means for deriving a title identification (Title_ID) of a legacy DVD disc, the Title_ID being a unique identifier of a title of the disc; and

means for linking the disc to a related web site based on the derived Title_ID.

2. The player of claim 1, wherein the Title_ID is derived in accordance with a method specified in a database.

3. The player of claim 2, further comprising means for determining whether the derived Title_ID matches an expected value indicated in the database that is associated with the specified method.

4. The player of claim 2, further comprising means for retrieving a universal resource locator (URL) in the database that is associated with the expected value if the derived Title_ID matches the expected value.

5. The player of claim 2, wherein the Title_ID is derived by retrieving a unique identifier from a pre-selected location of the disc.

6. The player of claim 5, wherein the pre-selected location is a burst cutting area (BCA).

7. The player of claim 5, wherein the pre-selected location is a private data sector.

8. The player of claim 1, wherein the Title_ID is a Volumn Set ID in a Universal Disc Format (UDF) file system of the disc.

9. The player of claim 2, wherein the Title_ID is derived based on selected data available on the disc.

10. The player of claim 1, further comprising:

11. The player of claim 10, further comprising:

means for storing a database containing a list of universal resource locators (URLs) for linking to web sites of preselected content providers, and a table of expected Title_IDs associated with the individual URLs;

means for determining whether the retrieved PVR_ID matches a corresponding URL in the list; and

13. The player of claim 12, wherein if the derived Title_ID fails to match any expected Title_ID in the table, the linking means links the disc to a general web site of a content provider using the corresponding URL.

14. The player of claim 12, further comprising:

means for accessing a source web site, if the derived Title_ID does not match any expected Title_ID in the table, the source web site containing a database which includes a list of universal resource locator (URL) links to related web sites and their associated PVR_IDs and Title_IDs;

means for searching a corresponding URL in the database based on the retrieved PVR_ID and derived Title_ID; and

means for linking the disc to a related web site using the corresponding matching URL.

15. The player of claim 12, wherein the Title_ID is derived based on selected data available on the disc.

38. The player of claim 14, further comprising means for periodically updating the database and the table stored by the storing means with information from the source web site.

39. The player of claim 14, further comprising means for caching an address of a website address each time the web site is accessed.

40. The player of claim 14, further comprising means for allowing a user to manually update the database and the table stored by the storing means with new information.

16. A WebDVD player, comprising:

means for retrieving a provider unique identification (PVR_ID) from a legacy DVD disc;

means for deriving a title identification (Title_ID) from the disc in a default manner, the Title_ID being a unique identifier of a title of the disc;

means for accessing a source web site containing a database which includes a list of universal resource locator (URL) links to related web sites and their associated PVR_IDs and Title_IDs;

means for searching a corresponding URL in the database based on the retrieved PVR_ID and derived Title_ID; and

means for linking the disc to a related web site using the corresponding matching URL.

17. The player of claim 16, wherein the database further includes a list of methods for deriving the Title_ID of a disc, the methods being associated with the Title_IDs which are derivable in accordance with the respective methods.

18. The player of claim 17, further comprising:

means for deriving the Title_ID of the disc in accordance with a method specified in the database, if the corresponding URL cannot be found by the searching means; and

means for determining whether the derived Title_ID matches a Title_ID indicated in the database that is associated with the specified method;

wherein the searching means searches an associated URL in the database based on the retrieved PVR_ID and the matching Title_ID;

wherein the linking means links the disc to a related web site using the associated URL.

19. The player of claim 18, wherein the method specified indicates retrieving a unique identifier from a pre-selected location of the disc.

20. The player of claim 18, wherein the Title_ID is derived based on selected data available on the disc.

21. A method for linking a legacy DVD disc to a related web site, the method comprising the steps of:

deriving a title identification (Title_ID) of the disc, the Title_ID being a unique identifier of a title of the disc; and

linking the disc to a related web site based on the derived Title_ID.
