Method for encoding n-ary value for coding of e.g. video stream, in e.g. video coder, involves associating ordered set of possible n-ary values with code word of set of code words according to predetermined rule

摘要

The method involves selecting (111) a dictionary of code words, taking into account a selection of an n-ary value of previously encoded information providing a set of code words arranged according to a predetermined criterion. A set of possible n-ary values is scheduled (112) by taking the previously encoded information into account, and an ordered set of possible n-ary values is delivered. The ordered set of possible n-ary values is associated (113) with a code word of the set of code words according to a predetermined rule, and the n-ary value is encoded (114) by the associated code word. Independent claims are also included for the following: (1) a device for encoding an n-ary value, comprising a selecting unit (2) a method for decoding an ary-value (3) a device for decoding an ary-value, comprising a selecting unit (4) a computer program for encoding an n-ary value.
