摘要：The present invention is directed to a variable coding of the bit-planes for aparticular source signal. This includes first partitioning or grouping the different bit-planes into embedded sub-signals and then coding each sub-signal. This technique

enables an encoder according to the present invention to control and achieve a desiredtrade-off point between scalability and coding-efficiency. Therefore, in cases where bit orbit-plane level granularity is not required, coding efficiency can be improved by

combining two or more bit-planes prior to coding. In addition, since the statistical natureof each bit-plane is different, the level of grouping used across the bit-planes can vary.
