Patent ID: 8867619

Claim:
An apparatus for generating a coded video sequence having a base scaling layer and enhancement scaling layer, comprising: a base motion compensator configured for calculating base motion data, which indicate how a block in a current picture has moved in relation to another picture in a group of pictures; a base motion predictor configured for calculating a base sequence of residual error pictures by using the base motion data; a base picture coder configured to generate a coded first scaling layer from the base sequence of residual error pictures; an enhancement motion compensator configured for determining enhancement motion data, wherein the enhancement motion compensator is formed to determine enhancement motion data adaptively and block by block by using the base motion data and to provide signalization information block by block, wherein the signalization information indicates, for each block, whether an enhancement motion data prediction has been performed at all by using the base motion data and of what type the enhancement motion data prediction is, wherein the signalization information is associated to each block, wherein the signalization information have a first state for a first block of the coded video sequence, the signalization information having a second state for a second block of the coded video sequence, the second block being different from the first block; an enhancement motion predictor for calculating an enhancement sequence of residual error pictures by using the enhancement motion data; and an enhancement picture coder for coding information about the enhancement sequence of residual error pictures and for coding the signalization information block by block to obtain a coded enhancement scaling layer, wherein the coded video sequence comprises the coded base scaling layer and the coded enhancement scaling layer, the coded enhancement scaling layer comprising coded signalization information associated with the first block, wherein any enhancement motion data for the first block is not contained in the coded enhancement scaling layer, the coded enhancement scaling layer further comprising, in addition to the coded signalization information associated with the second block, coded enhancement motion data for the second block.
