ABSTRACT:

TECHNICAL FIELD OF THE INVENTION
This invention relates generally to DVD technology and more particularly to a method and apparatus for providing additional user interactive software with the DVD data content.
BACKGROUND OF THE INVENTION
DVD is a relatively new technology that is just beginning to emerge in the commercial market place. In general, a DVD player reads, via a laser reader, a DVD disk to extract digital video and digital audio. The DVD player converts the digital video and audio into signals that are readily presentable on a television set, home theater, or a computer. A typical DVD disk includes substantially more information than is contained on a normal VCR (videocassette recorder) tape. For example, a DVD disk stores video data that is based on MPEG 2 (moving picture expert group), digitized audio (e.g., AC3, PCM, or MPEG) that corresponds to the video data, and sub-picture data which includes on-screen buttons for selecting different video and audio options. The options include jumping to various chapters of the video content, viewing special scenes of the video content, hearing additional commentary of the video content (e.g., director's and/or editor's cuts and comments), and viewing the video content from different angles.To select one of these options, the user activates the sub-pictures, via a remote control, and then selects the particular option via an on-screen cursor.
To control the hardware aspect of the DVD player (e.g, volume, picture quality, pause, rewind, etc.) and the accompanying displaying device (e.g., television, home theater, computer) the hardware provides applications which present on-screen buttons for the user to alter the hardware applications. The software that generates the on-screen buttons is generated by the manufacture of the DVD player or accompanying displaying device. As such, the on-screen buttons for hardware control typically have a different appearance than the on-screen buttons contained on the DVD disk. In addition to the different appearance, a separate controlling device is needed to pop-up the on-screen buttons of the hardware and other DVD commands. Thus, for a user to fully control the presentation of a DVD video, the user requires two control mechanisms; one for the hardware of the DVD system and another for the DVD content on the disk.
Therefore, a need exists for a method and apparatus that integrates the hardware applications of the DVD player and displaying device and DVD video user interactive content of the DVD disk into a single user controlled mechanism.
