Claim 12:
13. A method comprising:
obtaining 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;
obtaining 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;
determining, 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; and
generating output data using the at least one quantisation parameter,
wherein the method further comprises:
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; and
determining the at least one quantisation parameter based on the overall similarity score.
