Abstract
This encoding arrangement has an input (12) for receiving a sequence of samples to be encoded, an output for supplying encoded samples, processing circuits, more specifically: a differential circuit (20) for producing differential samples between the samples to be encoded and prediction samples, a prediction circuit (22) to produce prediction samples from the encoded samples. It is characterized in that the processing circuits are separated into encoding units (E1, E2, E3 and E4) for each effecting a processing operation on each sample to be encoded and that an interleaving member (60) is provided to convert the sequence of samples to be encoded into a sequence of interleaved samples so as to ensure that all the processing operations to be effected on a sample are indeed effected.
