FIELD: physics; communications.
SUBSTANCE: invention relates to encoding/decoding information values and specifically to entropy encoding using compact code books to generate an efficient code. The present invention is based on that, an efficient code for decoding information values can be obtained when two or more information values are grouped into a tuple in accordance with a tuple order, and when a code rule is used, in accordance with which the same code word is assigned to tuples with the same information values lying in different orders, and order information indicating the tuple order is extracted, and when a code word is output in relation to order information.
EFFECT: increased accuracy of encoding/decoding.
