Claim 19:
20. A non-transitory computer-readable medium storing computer program code comprising instructions that, if executed by a computer processor would cause an apparatus to:
obtain a first value of a first data element in a first set of data elements, the first set of data elements being based on a first time sample of a signal;
obtain a second value of a second data element in a second set of data elements, the second set of data elements being based on a second, later time sample of the signal;
deriving a measure of similarity between the first value and the second value, including generating an overall similarity score for the first time sample by combining a plurality of similarity scores, each of the plurality of similarity scores being associated with a different data element in the first set of data elements;
determine, based on the derived measure of similarity, at least one quantisation parameter useable in performing quantisation on data based on the first time sample of the signal, the at least one quantisation parameter being determined based on the overall similarity score; and
generate output data using the at least one quantisation parameter.
