Abstract

Decoder for decoding a residual signal from a data stream, configured to decode, from the data stream, a quantized prediction residual and at least one quantization error compensation signal; scale the quantized prediction residual to determine a scaled prediction residual; determine a reconstructed prediction residual based on the scaled prediction residual and the at least one quantization error compensation signal.
