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 12):
An encoder for encoding a picture into a scalable data stream, comprising:\n a base encoder for encoding the picture to obtain base layer data corresponding to a representation of the picture with a first sample bit depth; a predictor for providing a prediction of the picture based on the representation of the picture with the first sample bit depth, the prediction associated with the second sample bit depth that is higher than the first sample bit depth, the predictor including a mapper for performing, on the representation of the picture with the first sample bit depth, a mapping of samples of the picture from the first sample bit depth to the second sample bit depth based on a bit-shift operation to obtain the prediction of the picture; a residual encoder for encoding a prediction residual of the prediction to obtain enhancement layer data; and a combiner for forming the scalable data stream based at least on the base layer data, and the enhancement layer data.
