US 10,257,528 B2 · Method and apparatus for adaptive encoding and decoding based on image quality

Abstract

Disclosed herein are a method and apparatus that adaptively perform encoding and decoding based on image quality. An encoding apparatus may determine optimal Frames Per Second (FPS) for a video and may encode the video based on the determined FPS. Further, the encoding apparatus may provide improved temporal scalability. A decoding apparatus may select a frame to be displayed from among frames of a video depending on a required minimum satisfied user ratio. Through the selection of the frame, the decoding apparatus may provide improved temporal scalability.

Dependent claims

A video decoding method, comprising:

determining whether to decode at least one frame based on selection information for the frame;
and
decoding the frame if it is determined to decode the frame based on a temporal identifier of the frame.

Dependencies are inferred from the claim text.
