Abstract

An encoder for encoding a video stream or an image is described herein. The encoder receives an input video stream and outputs an encoded video stream that can be decoded at a decoder to recover, at least approximately, an instance of the input video stream. The encoder encodes a video stream by first identifying scene boundaries and encoding frames between scene boundaries using a set of parameters. For at least two different scene sequences, different sets of parameters are used, providing adaptive, scene-based encoding.
