A video coder performs motion-compensated prediction (1906, 1012, 1014, 1016) in both the base layer (1002) and an enhancement layer (1004) to then obtain motion data of the enhancement layer using the motion data from the base layer, and / or to predict sequences of residual error images after the motion compensated prediction in the enhancement layer using sequences of residual error images from the base layer using an interlayer predictor (1018). On the decoder side, an interlayer combiner is used to cancel this interlayer prediction. Thus, the data rate is improved compared to scalability schemes without interlayer prediction with the same image quality. |
