Abstract:
Scalable video coding is rendered more efficient by deriving/selecting a subblock subdivision to be used for enhancement layer prediction, among a set of possible subblock subdivisions of an enhancement layer block by evaluating the spatial variation of the base layer coding parameters over the base layer signal. By this measure, less of the signalization overhead has to be spent on signaling this subblock subdivision within the enhancement layer data stream, if any. The subblock subdivision thus selected may be used in predictively coding/decoding the enhancement layer signal.

Claim (Index 1):
A video decoder for decoding a video represented by a base layer signal and an enhancement layer signal, the video decoder comprising:\n a first decoding unit configured to reconstruct, using a processor, a base layer signal based on transform decoding of a base layer residual signal from a coded data stream; and a second decoding unit configured to reconstruct, using the processor, an enhancement layer signal from the coded data stream at least by: determining an inter-layer prediction signal based on a scalability refinement of the reconstructed base layer signal, and predictively reconstructing the enhancement layer signal using the inter-layer prediction signal, wherein the first and second decoding units are configured to reconstruct the base layer and enhancement layer signals, respectively, based on one of the following:\n bypassing both deblocking filtering and in-loop filtering, \n bypassing one, and using the other, of the deblocking filtering and the in-loop filtering, and \n using both of the deblocking and the in-loop filtering.
