ABSTRACT:
Characters which repeat between successive groups or lines on a page, are, except for an initial transmission, not transmitted, thereby decreasing the time for data transmission. Only the non-repeat characters between the successive groups or lines are transmitted along with a "map" (i.e. a sequence of numbers) indicative of the format of the repeat and non-repeat characters of the present group, or line, so as to enable a receiving station to reassemble the compressed data. A new map need not be sent, thereby further decreasing transmission time, if the transmission using an old map which has been previously transmitted compares favorably with the transmission using the new one.
