Abstract:
An improved concept for coding sample values of a spectral envelope is obtained by combining spectrotemporal prediction on the one hand and context-based entropy coding the residuals, on the other hand, while particularly determining the context for a current sample value dependent on a measure of a deviation between a pair of already coded/decoded sample values of the spectral envelope in a spectrotemporal neighborhood of the current sample value. The combination of the spectrotemporal prediction on the one hand and the context-based entropy coding of the prediction residuals with selecting the context depending on the deviation measure on the other hand harmonizes with the nature of spectral envelopes.

Claim (Index 4):
The context-based entropy decoder according to  claim 1 , further configured to determine the context for the current sample value dependent on a first measure for a deviation between a first pair of already decoded sample values of the spectral envelope in the spectrotemporal neighborhood of the current sample value and a second measure for a deviation between a second pair of already decoded sample values of the spectral envelope in the spectrotemporal neighborhood of the current sample value, with the first pair neighboring each other spectrally, and the second pair neighboring each other temporally.
