Adaptive grouping of parameters for enhanced coding efficiency

Abstract

The present invention is based on the finding that parameters including a first set of parameters of a representation of a first portion of an original signal (130a) and including a second set of parameters of a representation of a second portion of the original signal (130b) can be efficiently encoded, when the parameters are arranged in a first sequence of tuples (138) and in a second sequence of tuples (140), wherein the first sequence of tuples comprises tuples of parameters having two parameters from a single portion of the original signal (134a, 134b) and wherein the second sequence of tuples comprises tuples of parameters having one parameter from the first portion and one parameter from the second portion of the original signal (136a, 136b). An efficient encoding can be achieved using a bit estimator to estimate the number of necessary bits to encode the first and the second sequence of tuples, wherein only the sequence of tuples is encoded, that results in the lower number of bits.
