ABSTRACT:
Coding a signal is provided, wherein a first set of values is provided related to subsequent times in a first time interval of the signal, a second set of values is provided related to subsequent times in a second time interval of the signal, the first time interval having an overlap with the second time interval, the overlap including at least two subsequent times of the second interval, wherein at least one of the values of the second set related to the at least two subsequent times in the overlap is encoded with reference to a value of the first set which is closer in time to the at least one value of the second set than any other value in the second set.
