SYSTEM AND METHOD FOR UPGRADING AND EXTENDING THE FUNCTIONALITY OF PUBLISHED BLU-RAY DISC TITLES

摘要

An apparatus and method for upgrading and extending the functionality of published Blu-Ray disc titles using a player is disclosed. A disc is first read. A directory structure for the disc is then created in local storage on the player. The directory structure is updated using a first Java application. This invention is implemented, for example, in an improved system for upgrading a movie mode disc with Java full mode interactivity. Additionally, the method may be used to update Java applications on full mode titles with new versions of these applications, which may be made available over the Internet.
