  • Abstract
    SNR scalability, used in two-layer video coding, guarantees good base quality pictures at the expense of increased overall bit-rate. By understanding the inherent inefficiencies of enhancement layer coding we have developed an optimisation method called optimal coefficient adjustment in order to reduce overall bit-rates to levels consistent with single-layer operation
