Abstract
An operating system extension is used to implement embedded information on a DVD. The operating system extension examines DVD sector addresses requested from the DVD hardware. When address associated with an embedded link is requested, an application program that can run the embedded link is started, and the embedded link is provided to the application program. The system of the present invention has the advantage that it does not require modifying the DVD software program and thus can be used with a variety of different DVD software programs.
