Abstract:
1. A decoder for reconstructing a picture represented in an entropy encoded representation having a first and a second picture block, the picture blocks carrying picture information for picture areas smaller than the area of the picture and, by describing the picture information by transformation coefficients, generated by transforming a picture content within the picture areas into a spectral domain, wherein the first picture block is carrying the picture information in a first color-space representation and the second picture block is carrying the picture information in a second color-space representation, the decoder comprising: an entropy decoder arranged to derive the first and second picture blocks using an entropy decoding rule; and a color-space transformer arranged to perform a transformation of either the color-space representation of the first picture block to the second color-space representation onto the transformation coefficients of the first picture block or the color-space representation of the second picture block to the first color-space representation onto the transformation coefficients of the second picture block.
