Abstract
A multiuser display system in which the bit planes are shared by a plurality of user stations. A bus carries a superpixel containing bits from each of the bit planes in this system. Each user station is assigned particular bit planes and extracts the bits corresponding to the assigned bit planes from the superpixel. Double buffering within a window is made possible by providing two sets of bit plane identification registers.
