There is provided an apparatus and method for transmitting, over a general purpose data network, graphical data to a display device having a memory. The apparatus has a graphics component for generating graphical data in an appropriate format for direct transmission to corresponding addresses in the display device memory. Graphical data transmitted from the network interface specifies an address in the memory of that display device upon which an action is required. The apparatus is thus more efficient than conventional remote graphics systems. Direct transmission of graphical data to a memory address uses less network capacity as a single address value can generally be packed more tightly than a pair of coordinates. The invention simplifies the requirements placed on display devices: since the data is not transmitted as geometric coordinates there is no need for the display device to perform complicated arithmetic operations to convert incoming geometries to memory addresses. The network is preferably a general purpose data network and may be wireless.
