Abstract :
This paper proposes several improved schemes on the two-layer codec. In a two-layer coder, the packets produced by the base layer are set to the high priority and those produced by the second layer are low. Three improved schemes on the base layer are proposed. The base layer bits and/or the total bits have been significant reduced by these improved algorithms. In addition, the base images have been also remarkably enhanced
