Field: Audio-visual technology (Electrical engineering)
Classification: CPC H  A | IPC A  H

Claim 14:
15. The system of claim 9 where the system is controllable for switching between distinct private video streams either prior to or during the output of the ongoing composite stream, where switching includes any one of or any combination of:
controllably alternating the one or more projectors to switch from emitting the composite light (b) at a first linear angle of polarization to emitting the composite light (b) with a second and substantially orthogonal linear angle of polarization, where the one or more projectors is further adapted to comprise a switchable linear polarization filter responsive to electric signals for switching the linear angle of polarization, and
causing the video filtering lens to operate to transmit a second private video stream that is distinct from a first private video stream that would otherwise be transmitted, where the filtering lens comprises an active shutter for differentiating between temporally distinct private images comprising a private video stream, where the video filtering lens is further adapted to comprise a switchable linear polarization filter responsive to electric signals for switching the filtering of the composite light with characteristics (b) from a first linear angle of polarization to a second substantially orthogonal linear angle of polarization, and where the filtering lens switches between distinct private video streams by either one or both of operating the active shutter or operating the switchable linear polarization filter.
