Abstract
The present invention is based on the finding that pictures or a picture stream can be encoded highly efficient when a representation of pictures is chosen that is having different picture blocks, wherein each picture block is carrying picture information for picture areas smaller than the full area of the picture and when the different picture blocks are carrying the picture information either in a first color-space representation or in a second color-space-representation. Since different color-space-representations have individual inherent properties with respect to their describing parameters, choosing an appropriate color-space-representation individually for the picture blocks results in an encoded representation of pictures that is having a better quality at a given size or bit rate.
