Abstract
A method improves the efficiency of a compression technique by introducing a new parameter to be associated with a given probability range for events. When the new parameter is to be utilized, that parameter is associated with a table that matches codes to sequences of events. The coder receives the bit stream, detects a sequence of events and then reads the corresponding code from the table when the coder recognizes that the probability range with respect to the code corresponds to this new parameter. At the decoder the received bit stream is matched to table entries to determine the corresponding event sequence.
