Patent ID: 8019883

Claim:
A host system capable of supporting a first number of local display devices and an independent multiple second number of WiFi RF remote display systems, comprising: a graphics and display controller capable of supporting said first number of local display devices by supplying display sub frames via local display output paths and of supporting said multiple second number of WiFi RF remote display systems; a multi-display processor for simultaneously supporting said second number of WiFi RF remote display systems by receiving display sub frames from said graphics and display controller, and encoding said display sub frames by applying a compression algorithm that uses multiple frames; a frame compare function that detects when a given sub frame for a given remote display system is unchanged from a preceding sub frame for said given remote display system, and in response signals that said given sub frame does not need compression; a WiFi RF network controller that allows the host system to operate as a standard WiFi client on an infrastructure mode network, that utilizes only one standard infrastructure mode WiFi RF channel and does not switch said WiFi RF channel to standard WiFi ad-hoc mode or switch to utilizing a second RF channel, and that is used for selectively transmitting both to a WiFi router or access point using said one standard infrastructure mode WiFi RF channel and for maintaining network connectivity, and to said second number of WiFi RF remote display systems over a direct wireless connection using said standard infrastructure mode WiFi RF channel but without first transmitting said compressed sub frames in standard infrastructure mode; and means to connect said graphics and display controller, said multi-display processor, and said WiFi RF network controller to a CPU subsystem that is part of said host system.
