ABSTRACT:
A coder and/or decoder system and method are provided including a variable modulus. As an option, the modulus may reflect a steepness of a probability distribution curve associated with a compression algorithm (i.e. a negative exponential of the probability distribution). Moreover, the modulus may depend on a context of a previous set of data, while avoiding increasing as a function of a run length (i.e. a plurality of identical bits in a sequence).
