Abstract :
The authors propose an efficient conditional arithmetic coding scheme for tree structured vector quantisation (TSVQ) systems which effectively exploits interblock correlation. A memory reduction method for the conditional arithmetic coding scheme is also presented. Simulation results show that the proposed scheme provides remarkable bit-rate reduction performance
