Patent ID: 7430018

Claim:
A method for timesharing of a display screen in a multimedia display system, said method comprising: said multimedia display system receiving multiple program feeds; wherein each of said multiple program feeds having same frame rates; multiplexing frames from each of said multiple program feeds, by interleaving one frame from each of said multiple program feeds sequentially in the same repeating order; displaying said multiplexed frames from each of said multiple program feeds at a boosted frame rate; wherein said boosted frame rate is equal to the number of interleaved program feeds times an original viewing frame rate; setting a blanking period between each frame raster on said display screen; defining a threshold blanking period; if number of said multiple program feeds increases such that said blanking period is shorter than said threshold blanking period, then increasing raster speed, to reduce frame display duration; wherein said raster speed is preconfigured to a set of raster speeds; automatically adjusting an attribute of said display screen, to compensate for reduction of display brightness, due to any reduced display duration; signaling viewer eye pieces about any changes in said raster speed; wherein one of multiple-viewer apparatuses for viewing said display screen comprising a viewing strobe, and a first rotating disc with one or more slots angularly uniformly distributed, with a slot opening in a user's line of sight; adjusting said slot opening, using an adjustable mask, or using a second rotating disc; wherein said second rotating disc rotating at the same speed, but out-of-phase, with respect to said first rotating disc; a phase lock module, with a feedback mechanism, adjusting any deviation in operation of said first rotating disc, using a synchronization signal; wherein said slot opening is adjusted inversely proportional to said raster speed; synchronizing said multiple program feeds with audio data; selecting one of said multiple program feeds to view; transmitting a frame synching signal to each of said multiple-viewer apparatuses which is associated with said selected one of said multiple program feeds to view; and wherein frequency of said frame synching signal is the same or a whole fraction of said original viewing frame rate.
