METHODS AND APPARATUSES INCLUDING AN ENCODING SYSTEM WITH TEMPORALLY ADAPTIVE QUANTIZATION

摘要

Examples methods and apparatuses including an encoding system with temporally adaptive quantization are described herein. An example apparatus may include an encoding system configured to receive a coding unit of a video signal. The coding unit may include a plurality of sub-coding units. The encoding system may be further configured to determine spatial complexity statistics and motion estimation statistics associated with a sub-coding unit of the plurality of sub-coding units. The encoding system may be further configured to modify a quantization parameter associated with the coding unit based on the spatial complexity statistics and the motion estimation statistics, and to encode the sub-coding unit using the modified quantization parameter.
