Claim 4:
5. The decoder of claim 4, wherein the memory further stores instructions that, when executed by the processor, cause the processor to, if ante intra prediction mode is an angular mode,
if the split mode flag indicates a first split mode,
in deriving a predictor for the current partition depending on one or more already reconstructed samples neighboring the current partition in a manner depending on the intra-coding mode for the current block, subject the already reconstructed samples to a first interpolation filtering that depends on the angular mode; and

if the split mode flag indicates a second split mode,
in reconstructing the current block by spatial intra prediction, deriving a predictor for the current block depending on the one or more already reconstructed samples neighboring the current block in a manner depending on the intra-coding mode for the current block by subjecting the already reconstructed samples to a second interpolation filtering that depends on the angular mode,

wherein the first interpolation filtering differs from the second interpolation filtering in a mean number of already reconstructed samples on which each sample of the predictor within the current block depends.
