US Patent 7184653 Unique digital content identifier generating methods and arrangements

In accordance with certain aspects of the present invention, enhancements have been developed to further extend the performance of the generic DVD navigator component. Of significance herein, was the need to assign a unique identifier to DVD discs and the like. Doing so allows player applications to easily identify, catalogue and associate information with each disc. Previous “unique” ID algorithms have failed to produce useful and reliable identifiers. Thus, improved methods and arrangements are provided for use in the generic DVD navigator that produces substantially, statistically unique disc IDs.
