ABSTRACT:
In an arithmetic encoder and/or a corresponding arithmetic decoder, an A parameter, related to the size of a value interval, is truncated prior to multiplying the A parameter times the probability of a symbol, and the carry-over of the multiplication is controlled in the re-normalizing step in the encoder or decoder.
