The method involves encoding an image region (MB) based on a set of probability models. A set of probability models used in encoding branches (1-3) for encoding is based on a common set of probability models, where the common set is valid for the encoding branches, which consider frequencies of symbols in the image regions of the encoding branches. The common set of probability models is updated at predetermined time intervals based on the frequencies that are adapted in a temporally preceding encoding cycle (CC). Independent claims are also included for the following: (1) a method for decoding coded symbols (2) a method for coding and decoding a sequence of digitized images (3) a device for encoding symbols from a sequence of digitized images (4) a device for decoding coded symbols (5) a codec for coding and decoding a sequence of digitized images. |
