Abstract:
A more efficient way of addressing different bit-depths, or different bit-depths and chroma sampling format requirements is achieved by using a low bit-depth and/or low-chroma resolution representation for providing a respective base layer data stream representing this low bit-depth and/or low-chroma resolution representation as well as for providing a higher bit-depth and/or higher chroma resolution representation so that a respective prediction residual may be encoded in order to obtain a higher bit-depth and/or higher chroma resolution representation. By this measure, an encoder is enabled to store a base-quality representation of a picture or a video sequence, which can be decoded by any legacy decoder or video decoder, together with an enhancement signal for higher bit-depth and/or reduced chroma sub-sampling, which may be ignored by legacy decoders or video decoders.

Claim (Index 3):
The decoder according to  claim 1 , wherein the prediction module is adapted to piecewise linearly map the samples of the first sample bit depth to the second sample bit depth by use of interpolation point information retrieved from the scalable data stream.
