    摘要: A method for encoding a plurality of signal values is described, wherein the signal values are grouped into a first subgroup and a second subgroup, the signal values of the first subgroup are compared to the signal values of the second subgroup and based on the result of the comparison it is decided whether the signal values of the first subgroup are bit-plane encoded with higher priority than the signal values of the second subgroup.
