Abstract :
It is shown how to encode and transmit binary Markov sources using a set of block codes called MELCODE. Fill symbol control is used to manage the transmission order of codewords with limitation of memory size. MELCODE is extended to arithmetic-type code, and the calculation accuracy of coding address is clarified. Block codes and arithmetic codes are compared in terms of memory size and coding efficiency through the simulation of bilevel image coding, showing an improvement in coding efficiency
