Abstract

See full text

Arithmetic encoder for encoding a plurality of symbols is configured to derive an interval size information for an arithmetic encoding of one or more symbol values to be encoded on the basis of one or more state variable value, in a first mode of operation, and to update the one or more state variable values and/or the interval size information for an encoding of one or more subsequent symbol values to be encoded in the first mode; in a second mode, the arithmetic encoder is configured to disable an update of the one or more state variable values and/or of the interval size information. Additionally, further embodiments of arithmetic encoders and decoders and video encoders and decoders are described.
