摘要：An offset-difference coding process for data encoding and decoding whereinfor each of the paired input data, the encoding process first determines the greater ofthe two input data, then calculates the difference between the two input data, replaces

the larger input data with the calculated difference, and encodes the calculateddifference and the smaller input data. The offset-difference coding process alsogenerates an indicator if the larger input data that is replaced by the calculateddifference is not statistically larger than the smaller input data. A composite offset-difference coding process for data encoding and decoding further compares thecalculated difference with either a predetermined first threshold or a predeterminedsecond threshold in response to whether the larger input data is statistically larger thanthe smaller input data, and determines whether to replace the larger input data with thecalculated difference in response to whether the calculated difference exceeds thepredetermined threshold. The composite offset-difference coding process also

generates an identifier if the calculated difference does not exceed the threshold as wellas an indicator if the larger input data that is replaced by the calculated difference is notstatistically larger than the smaller input data.
