Abstract:
A peripheral device is coupled to a system bus of an apparatus via a system bus compatible cable, and transmits to an operating system a request to transmit to the output multiple image stream 3D video data and a request to access a video subsystem for monitoring a status of page flip signals. The peripheral device transmits sync signals to at least one output of the peripheral device representing the page flip signals detected in response to monitoring page flip signal status. The apparatus transmits the multiple image stream 3D video data to the output. The multiple image stream 3D video data is received at a stereographic projection apparatus input. Each stream data contains a plurality of frames. The stereographic projection apparatus comprises an alternating polarizing filter, synced with the alternately projecting images, for separately filtering images from each of the image stream 3D video data at different polarization angles.
