APPARATUS, METHOD AND ARTICLE FOR A DUAL-PROGRAM DISPLAY

摘要

A system for enabling two different users to independently view and listen to two completely different programs on the same display at the same time is provided. A user wears eyeglasses with filters to filter out light from the program which the user does not want to view, while allowing the light from the program the user does want to view to be seen by the user. Successive frames of a first program are displayed using light polarized in one direction in an alternating manner with frames of a second program using light polarized in another direction. A first user wears glasses with lenses configured to filter out the light from the second program while a second user wears glasses to filter out the light from the first program. Thus, while wearing the glasses, the first user can see the first program while watching the display, but not the second program. Simultaneously, while wearing the other glasses, the second user will see the second program, but not the first program.

主权项

1. A display control unit, comprising:
a controller including a microprocessor configured to perform logical operations and send signals to a presentation device; a memory store; and a non-transitory computer readable storage medium having computer executable instructions thereon that cause the controller to
transmit first and second video signals for alternating presentation on a single display of the presentation device in synchronization with a constant refresh rate of the display;transmit first and second audio signals to first and second headsets respectively, andstore dual display configuration parameters in the memory store; and a bus that provides a communication path among the controller, the memory store, and the non-transitory computer readable storage medium.
