Method and apparatus for processing and subsequently displaying transmitted image data on an active-addressed display device

An electronic device for receiving and displaying information on a display driven according to active addressing techniques in which the display is driven with orthonormal signals, the electronic device comprising:

• a receiver for receiving addresses;
• a memory coupled to the receiver for storing predetermined addresses and groups of column values, wherein each predetermined address is associated with a single group of column values, and wherein each group of column values has been previously derived by transforming a single column of image data values into another domain according to the active addressing techniques and subsequently stored in the memory prior to operation of the data communication receiver, and wherein each group of column values is to be utilized for driving a single column of the display;
• determining means coupled to the receiver and the memory for determining which ones of the groups of column values are associated with predetermined addresses that are equivalent to the addresses received by the receiver;
• and
• column signal generating means coupled to the determining means for generating column signals from the ones of the groups of column values, wherein the column signals are utilized to drive the columns of the display in accordance with the addressing techniques.
