Abstract
A method encoding data values of a data set, including: selecting one of plural complementary sub-ranges of a code values set according to a current input data value, the code values set defined by a range variable; assigning the current input data value to a code value within the selected sub-range; modifying the code values set depending on the assigned code value and size of the selected sub-range; detecting whether the range variable is less than a predetermined minimum size and if so, successively increasing the range variable to increase the code values set size to at least the predetermined minimum size; outputting an encoded data bit in response to each size-increasing operation; after encoding a group of input data values, setting the range variable to a value selected from a predetermined subset of available range variable values, each subset value having at least one least significant bit of zero.
