Abstract
An encoder generating encoded data. The encoder comprising an analysis unit for analysing portions of data to be encoded, and for directing the portions to one or more encoding units, the encoding units are operable to encode the data portions to generate encoded data. The one or more encoding units are operable to employ mutually different encoding algorithms when encoding the one or more portions. At least one encoding unit of the one or more encoding units is operable to compute data values present in each portion received thereat, to sub-divide the data values into at least two sets, to compute at least one aggregate value for a given set derived from the data values present in the given set. A corresponding decoder for decoding data generated by the encoder executes an inverse of encoding steps employed in the encoder.
