  • Method and apparatus for providing additional DVD data
    Patent number: 6507696
    Abstract: A method and apparatus for displaying DVD and/or application data is accomplished by detecting selection of a user interaction request that is requesting the display of a DVD subpicture or an application subpicture. Once the user interaction request is detected, the system determines the particular type of the request; i.e., whether the request is for a DVD data stream or an application data stream. Note that the DVD data stream includes DVD video data, DVD audio data, and DVD subpicture data. Simliarly, the application data stream includes at least one of application video data, application audio data, and application subpicture data. When the user interaction request relates to the application data stream, the application data stream is displayed only or merged with the DVD data stream.
