A method for encoding high resolution data to a form having a reduced number of bits can include predefining a plurality of high-output-resolution output patterns, associating respective output-resolution output patterns of the plurality with respective encoded resolution bit patterns, receiving a block of input-resolution input data, determining a respective difference between a pattern of the received block of input data and the respective output-resolution output patterns, selecting a respective output-resolution output pattern associated with a lowest respective difference to be a representative output pattern for the received block of input data and encoding the received block of input-resolution input data as the respective encoded resolution bit pattern associated with the selected respective representative high-output-resolution output pattern. A system includes a library of output patterns in association with encoded resolution bit patterns, a block analyzer, a block selector and an encoder.
