Abstract:
1. A hardware implemented compression unit for compression of parameters, the parameters including a first set of parameters including a representation of a first portion of an original signal, the parameters further including a second set of parameters including a representation of a second portion of the original signal, the second portion neighboring the first portion, comprising: a supplier for supplying a first tuple and all remaining tuples of a first sequence of tuples using only tuples having parameters from one single set of parameters, and to supply a first tuple and all remaining tuples of a second sequence of tuples using only tuples having at least one parameter from the first set of parameters and at least one parameter from the second set of parameters; a bit estimator for estimating a number of bits necessary to encode the sets of parameters using the first sequence of tuples and to encode the sets of parameters using the second sequence of tuples, based on an encoding rule; and a provider for providing encoded blocks, the provider being operative to provide the encoded blocks using the sequence of tuples resulting in a lower number of bits, and for providing a single sequence indication for one encoded block indicating the sequence of tuples from which the encoded blocks are derived, wherein the original signal is an audio signal received by hardware; and wherein the tuples have a number of parameters, the number being at least two, and wherein an n-dimensional code is used for encoding the tuples, the number n of the dimension of the code being equal to the number of parameters of the tuples.
