VIDEO CODING AND DECODING METHODS WITH HIERARCHICAL TEMPORAL FILTERING STRUCTURE, AND APPARATUS FOR THE SAME

摘要

A method and apparatus for video coding and decoding with hierarchical temporal filtering structure are disclosed. A video encoding method in a temporal level having a hierarchical temporal filtering structure, includes generating prediction frames from two or more reference frames that temporally precede the current frame; generating a residual frame by subtracting the prediction frames from the current frame; and encoding and transmitting the residual frame.
