Abstract
An encoder includes data processing hardware which is operable: to divide input data into a plurality of blocks or packets; to apply a plurality of transformations to content of the blocks or packets to generate corresponding transformed data; to check a quality of representation of the transformed data prior to application of the transformations to determine whether or not the quality of representation of the transformed data satisfies one or more quality criteria; if the quality of representation of the transformed data does not satisfy the one or more quality criteria, to sub-divide and/or to combine the one or more blocks or packets further and repeating the transformation step; and if the quality of representation of the transformed data satisfies the one or more quality criteria, to output the transformed data to provide encoded output data representative of the input data to be encoded.
