Abstract
A system for transcoding a video signal into a transcoded video signal includes a drastic scene change detection module that detects a drastic scene change in a sequence of images, wherein the drastic scene change indicates a change in scene complexity. A transcoder section generates the transcoded video signal, wherein, when the drastic scene change is detected, a quality parameter is adjusted in at least one of the sequence of images.
