Abstract

A higher compression rate or better rate/distortion ratio is achieved by adopting or predicting second coding parameters used for encoding a second view of the multi-view signal from first coding parameters used in encoding a first view of the multi-view signal. The redundancies between views of a multi-view signal were found to be not restricted to the views themselves, such as the video information thereof. Rather, the coding parameters in parallely encoding these views show similarities which may be exploited in order to further improve the coding rate.
