Abstract

This disclosure describes techniques for binary arithmetic coding in video coding and video encoders and decoders for performing such techniques. In some examples the techniques may support binary arithmetic coding that supports slower adaptation rates and accounts more extreme probabilities (i.e. probabilities closer to 0 and 1) while maintaining relatively small tables.
