Adaptive grouping of parameters for enhanced coding efficiency

A method 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, the method comprising:

• supplying a first tuple and a second tuple, each tuple having at least two parameters, the first tuple having two parameters from the first set of parameters and the second tuple having one parameter from the first set of parameters and one parameter from the second set of parameters;
• estimating a number of bits necessary to encode the sets of parameters using a first sequence of tuples including the first tuple and to encode the frames using a second sequence of tuples including the second tuple, based on an encoding rule;
• providing encoded blocks using the sequence of tuples resulting in a lower number of bits;
• and
• providing a sequence indication indicating the sequence of tuples from which the encoded blocks are derived.

A method for decoding encoded blocks 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, and for processing a sequence indication, the method comprising:

• decompressing, using a decoding rule depending on an encoding rule used for encoding sequences of tuples, the encoded block of parameters to derive a sequence of tuples of parameters, each tuple having at least two parameters;
• receiving the sequence indication indicating a used sequence of tuples from a number of different sequences underlying the encoded block;
• and
• building the sets of parameters using the information of the used sequence of tuples.
