Abstract:
Method for coding/decoding a target range from a value range, in which a recurrence step is repeated in a coding/decoding step for the target range until code bits are found for the target range to be coded, or the target range to be decoded is found using the code bits; in the recurrence step, an interval of the value range in which the target range to be coded/decoded is located is divided into two new intervals, a single bit indicates in which of the new intervals the target range to be coded/decoded is located, and the new interval indicated by the single bit is used as the interval for the next recurrence step, whereby the code bits for the target range to be coded or the target range to be decoded is found when the interval falls below a minimum quantity, wherein, in at least one recurrence step, a probability distribution for the target range in the interval is used to select the new intervals.
