Abstract (en)

[origin: WO2006056529A1] The invention relates to a method for producing a video data stream for an expansion signal, wherein a base signal represents a first video quality degree and the expansion and base signals jointly represent a second video quality, only second syntax elements of the expansion signal which are not describable by the first syntax element of the base signal are taken into account during encoding, the coding mode of a video encoding method which is encodable by all syntax elements is selected by means of a statistical method, said second syntax elements are not representable by one or several first syntax elements and the method brings about to the production of the shortest video data stream for said second syntax elements. A decoding method for restoring the expansion signal from the video data stream, encoding and coding devices are also disclosed.
