Patent ID: 7636480

Claim:
A method for encoding high resolution data associated with a relatively large number of bits to an encoded form having a relatively reduced number of bits, the method comprising: predefining a plurality of high-output-resolution output patterns; associating respective high-output-resolution output patterns of the plurality with a respective encoded resolution bit pattern having the reduced number of bits; receiving a block of high-input-resolution input data; determining a respective difference between a pattern of the received block of high-input-resolution input data and each of the respective high-output-resolution output patterns; selecting a respective high-output-resolution output pattern associated with a lowest respective difference to be a representative high-output-resolution output pattern for the received block of high-input-resolution input data; and encoding the received block of high-input-resolution input data as the respective encoded resolution bit pattern having the reduced number of bits associated with the selected respective representative high-output-resolution output pattern.
