摘要：Binarization a data value comprises binarizing the minimum of the data valueand a predetermined cut-off value in accordance with a first binarization scheme, in order
to yield a primary prefix. If the data value is greater than the cut-off value, binarizing adifference of the data value minus the predetermined cut-off value in accordance with asecond binarization scheme to obtain a binary suffix, the first binarization scheme beingdifferent from the second binarization scheme, and appending the primary suffix to theprimary prefix is performed. A very effective compression of data values may be achievedby using the binarization scheme for preparing the syntax elements for the arithmeticcoding, the binarization scheme substantially being a combination of two differentbinarization schemes, and by using binary arithmetic coding instead of m-ary arithmeticcoding for coding the binarized syntax elements.
