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 15):
A non-transitory computer-readable medium for storing data associated with a video, comprising a data stream stored in the non-transitory computer-readable medium, the data stream comprising information related to a base layer and an enhancement layer of the video including a base layer residual signal of a base layer signal and a transform coefficient block of transform coefficients representing an enhancement layer signal, wherein the data stream is decoded using a plurality of operations including:\n decoding, using a processor, the base layer residual signal; and reconstructing, using the processor, the enhancement layer signal by decoding the transform coefficient block of the transform coefficients representing the enhancement layer signal 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, decoding (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.
