An electronic system that produces an enhanced spatial television-like
audio-visual experience is disclosed. Unlike normal television, the
system enables the viewer to control both the viewing direction and
relative position of the viewpoint with respect to the movie action. In
addition to a specific hardware configuration, this patent also relates
to a new video format which makes possible this virtual reality like
experience including a system by which multi-channel audio can be
recorded in addition to visual information onto a single data channel
which is compatible with existing television and audio-visual standards
and an optical tracking system to provide both angular and spatial
position information to control the display of said imagery and spatial
audio.
