Abstract: System and methods for allowing a person or a process to select between multiple spatial-temporal sub-channels provided within a multi-sub-channel video-audio stream being output to a viewer, where selection causes a specific sub-channel within the stream to be received when viewing through an active filter device. A single image of the stream comprises at least two spatial sub-channels and the stream comprises at least two temporal sub-channels, where spatial sub-channels are formed using polarization and restrictive narrow-band color filtering. The stream is output by a display or projector and viewed using an active filter device. The active filter device comprises a combination of an active spatial channel filter and an active temporal channel filter and is responsive to sub-channel selections indicated through either a manual or automatic content selection means, where an automatic selection means includes a program for example directing the person through an adjustable story movie.

Abstract: System and methods for providing simultaneous public and private video, where a private viewer looking through an eye filter perceives the private video while a public viewer not looking through an eye filter perceives the public video. First a public image is generated and linearly polarized. The public image is then modulated to further encode a private image using an additional liquid crystal modulating layer. The modulated public image including the encoded private image is then received and filtered by various embodiments of passive or active eye filters comprising various combinations of spatial, temporal or spatial-temporal filters. The eye filters optionally include identifying means such that the system provides customized private images to selected eye filters. Means for providing private audio simultaneous with the private video are also shown. The system can be implemented as either a display or a projector and used in a destination-wide gaming system.
