Abstract:
The coding efficiency of scalable video coding is increased by substituting missing spatial intra prediction parameter candidates in a spatial neighborhood of a current block of the enhancement layer by use of intra prediction parameters of a co-located block of the base layer signal. By this measure, the coding efficiency for coding the spatial intra prediction parameters is increased due to the improved prediction quality of the set of intra prediction parameters of the enhancement layer, or, more precisely stated, the increased likelihood, that appropriate predictors for the intra prediction parameters for an intra predicted block of the enhancement layer are available thereby increasing the likelihood that the signaling of the intra prediction parameter of the respective enhancement layer block may be performed, on average, with less bits.

Claim (Index 19):
A scalable video encoder, comprising:\n a block-based encoding unit configured to: encode, using a processor, a base layer signal of a video into a data stream by block-wise prediction; and encode, using a processor, an enhancement layer signal of the video into the data stream by block-wise prediction that includes using a current intra prediction parameter to encode current block of the enhancement layer signal, comprising:\n checking whether a neighboring block of the enhancement layer signal is intra-encoded, wherein the neighboring block neighbors the current block of the enhancement layer signal, \n responsive to checking the neighboring block, inserting a neighboring intra prediction parameter of the neighboring block\u2014into a set of intra prediction parameters for the current block, \n checking whether a co-located block of the base layer signal is intra-encoded, wherein the co-located block is co-located relative to the current block of the enhancement layer signal, \n responsive to checking the co-located block, inserting a base-layer intra prediction parameter of the co-located block of the base layer signal into the set of intra prediction parameters for the current block, \n determining the current intra prediction parameter for the current block as at least one of the set of intra prediction parameters, and \n inserting into the data stream a syntax element, which indicates the at least one of the set of intra prediction parameters.
