    performing a first compression technique comprising;

    compressing said data block in received form with a first encoder to provide a first compressed data block, andcompressing said first compressed data block with a second encoder to provide a second compressed data block;

    comparing said second compressed data block against a threshold, wherein said threshold is indicative of data expansion; and

    providing said second compressed data block to a device, if no data expansion is determined to have occurred based on said comparing.
