Abstract
A selective call signaling system (10) capable of facsimile communication with a selective call receiver (40) having an active addressing display (100) comprising picture elements (pixels) (108) controlled by a plurality of first and second electrodes (106, 104). A data compressor (12) compresses the data. A transmitter (30) transmits the compressed data organized in frames to the selective call receiver (40). The selective call receiver (40) comprises a receiver (60) receiving the compressed data; the active addressing display (100) displaying the compressed data. The active addressing display (200) comprises a controller (500) controlling the plurality first electrodes (106) by a plurality of periodic first drive signals (400) represented as a sequency ordered Walsh Hadamard transform (WHT) matrix (300) and the plurality of second electrodes (104) by a plurality of second drive signals responsive to the compressed data. A processor (510) calculates the plurality of second drive signals directly from the compressed data and identifies a plurality of hierarchical tree structures (FIG. 11 ) corresponding to the WHT matrix (300) for processing the frames of compressed data directly with hierarchical tree structures (FIG. 11).
