Abstract
A method of decoding a received set of encoded data is provided. The set of encoded data represents information that comprises a plurality of data elements having values within a range of values and that has been compressed by way of entropy encoding. The method comprises: receiving data comprising the set of encoded data and a set of banded distribution data, wherein the set of banded distribution data comprises one or more pairs of values, each pair comprising a sub-range value indicating a respective sub range of the range of values and a probability value representing a probability of a data element of the plurality of data elements having a value within the respective sub-range; and reconstructing the information that has been compressed, by way of performing entropy decoding, based upon a probability distribution defined by the set of banded distribution data, upon the set of encoded data. A method of compressing information comprising a plurality of data elements having values within a range of values so as to obtain a set of encoded data is also provided.
