Patent ID: 7667707

Claim:
A graphics and display system capable of supporting multiple displays, comprising: a System-On-Chip (SOC) integrated circuit including 2D and 3D drawing engines, video processing hardware, and a display controller that share a memory subsystem, that concurrently generate multiple display frames which may each correspond to a display frame at a respective remote display system, and that support a first number of local display devices via local display paths, and a second number plurality of remote display systems, not limited by the first number, each enabling a respective remote user to provide user inputs; a frame buffer which stores display frames organized as sub frame memory areas representing display frame tiles for said remote display systems; frame compare means that tracks on a frame or sub-frame basis which portions of a display have changed based on a checksum of a grid of a prior frame's display data; and display data encoder means that compresses the display data from the frame buffer; means for connecting said SOC to a host CPU in a host computer system running software that works with said SOC to identify modified display frames or sub frames so that only modified display data will be transferred via a network subsystem to corresponding ones of said remote display systems; and means for connecting said SOC to a network subsystem in communication with said second number of remote display systems and for enabling said plurality of remote display systems to transmit user inputs to said SOC.
