Abstract: This paper proposes a new variable-bit-rate layered coding algorithm based on zubband coding. It makes full use of the advantage of variable-bit-rate transmission of ATM networks and has the ability to compensate picture degradation caused by cell loss, thus a high quality stable video communication is realized. The coding algorithm, cell composition method and simulation results are given. -
