Method and apparatus for rate distortion optimisation

Abstract

There is provided a method of optimising Rate Distortion Optimisation candidate assessment in hardware apparatus, comprising determining which Rate Distortion Optimisation candidates out of aplurality of candidates are separately processable, determining a processing delay of critical portions of candidate assessment hardware, determining a rule set governing how the separately processable candidates may be ordered for processing, determining an optimised processing order for processing the separately processable candidate assessments, dependent on the processing delay of critical portions of the candidate assessment hardware and the determined rule set, and processing the candidates according to the determined processing order. There is also provided an apparatus for carrying out the improved Rate Distortion Optimisation method.
