Your data is now written with ANS if using e.g. Apple, Facebook, Google, Linux, soon JPEG XL: https://en.wikipedia.org/wiki/Asymmetric_numeral_systems

This patent covers rANS variant which is used for example in https://en.wikipedia.org/wiki/JPEG_XL - if granted, only Microsoft will be able to make its hardware encoders/decoders.

Lots of materials about ANS: https://encode.su/threads/2078-List-of-Asymmetric-Numeral-Sy...
