Abstract
Abstract A virtual reality television system includes a video capture and encoding system for capturing and encoding the surface geometries and colors of objects and their background as the objects interact during a live action event taking place in a live action space; an audio capture and encoding system for capturing and encoding spatial sound sources emanating from the live action space as a result of the objects interacting therein, as well as ambient sounds emanating from a periphery area around the live action space and commentators' voices; and a rendering system responsive to viewer manipulated input devices for rendering a visual and auditory experience of the live action event from the perspective of a viewer selected virtual viewpoint related to the live action space.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
189 words
An interactive television system providing viewer selectable virtual positions including all points within a three-dimensional space for experiencing an event occurring in said three-dimensional space, comprising: a capture and encoding subsystem including means for generating video signals from different viewpoints of said objects within said live-action space such that said video signals communicate information indicative of the locations and three-dimensional shapes of said objects, and means for processing said video signals to generate encoded data including the locations and three-dimensional shapes of said objects; and a rendering subsystem including means responsive to physical actions initiated by a viewer for generating at least one control signal indicative of a virtual position in said three-dimensional space; means for receiving said at least one control signal, said encoded data, and audio information associated with said event, and generating in response thereof, display signals and audio signals relative to said virtual position; means responsive to said display signals for providing a simulated viewing experience relative to said virtual position to the viewer; and means responsive to said audio signals for providing a simulated hearing experience relative to said virtual position to the viewer.
Claim 2
Dependent Claim
