Abstract
In a system and method for transmitting and displaying multiple different views of a scene, three or more simultaneous scene signals, representing multiple different views of a scene, are provided by an appropriate camera arrangement to a spatial multiplexer. The size and resolution of the scene signals are reduced as necessary to combine the multiple scene signals into two super-view signals. The super-view signals are encoded using compression based on redundancies between the two super-views and then transmitted. A decoder receives the transmitted data signal and extracts the two super-view signals according to the inverse of the encoding operation. A spatial demultiplexer recovers the individual scene signals from the decoded super-view signals in accordance with a defined multiplexed order and arrangement. The scene signals are then interpolated as needed to restore the original resolution and size and subsequently displayed.
