Abstract:
A subblock-based coding of transform coefficient blocks of the enhancement layer is rendered more efficient. To this end, the subblock subdivision of the respective transform coefficient block is controlled on the basis of the base layer residual signal or the base layer signal. In particular, by exploiting the respective base layer hint, the subblocks may be made longer along a spatial frequency axis transverse to edge extensions observable from the base layer residual signal or the base layer signal.

Claim (Index 8):
A scalable video encoder comprising:\n a first block-based encoding unit configured to encode, using a processor, a base layer residual signal of a base layer signal into a coded data stream; and a second block-based encoding unit configured to encode an enhancement layer signal by encoding, into the coded data stream using the processor, a transform coefficient block having transform coefficients that represent an enhancement layer signal, the encoding including:\n selecting, for the transform coefficient block, a subblock subdivision from a set of possible subblock subdivisions based on transform coefficients of a portion of the base layer residual signal or the base layer signal, wherein the transform coefficient block is subdivided into subblocks in accordance with the subblock subdivision, \n traversing positions of the transform coefficients in units of the subblocks such that all positions within one subblock are traversed before proceeding to a next subblock in a subblock order defined among the subblocks, and \n for a current-subblock being traversed, encoding into the data stream (a) a first syntax element indicating as to whether the current subblock comprises any significant transform coefficient, and (b) second syntax elements indicating levels of transform coefficients within the current subblock, if the first syntax element indicates that the current-subblock comprises a significant transform coefficient.
