CONTENT-ADAPTIVE B-PICTURE PATTERN VIDEO ENCODING

摘要

A method of video encoding is disclosed which is content adaptive. The encoding method is automatically adjusted to optimize the encoding, the adjusting depending on the content of the pictures being encoded. A system for implementing the method and a non-transitory computer-readable storage medium for storing instructions of the method are also disclosed.

主权项

1. A method for content adaptive video encoding, the method comprising:
selecting a set of successive pictures; decomposing the set of successive pictures into one or more groups of pictures (GOPs) to form a first GOP decomposition of the set of successive pictures; repeating the decomposing, thereby forming a plurality of distinct GOP decompositions of the set of successive pictures, the plurality including the first GOP decomposition; determining, for each GOP decomposition in the plurality of distinct GOP decompositions, a GOP decomposition rate-distortion (RD) cost by determining a GOP RD cost for each GOP in that GOP decomposition; and selecting a GOP decomposition from the plurality of distinct GOP decompositions having a minimum GOP decomposition RD cost for use in encoding the successive pictures in the set of successive pictures.
