Abstract
There is described a method of processing data, comprising: determining if the one or more residual data blocks are to be removed from a set of encoded data or data to be encoded, the determination comprising at least one of: determining a property of the one or more residual data blocks; and determining if all the elements in the one or more residual data blocks have a threshold value of non zero values.
