<p>The present invention provides a method for encoding, a method for decoding, an apparatus for encoding and an apparatus for decoding a video signal. At the encoder side, filter data are determined separately for at least two of the prediction signal, prediction error signal and reconstructed video signal. The filter data are encoded based on statistical relation between the at least two signals. In this way, the quality of the filtered signal may be improved and the overhear caused by the filter data signalling is reduced. At the decoder, the filter data is decoded based on statistical dependencies between the at least two signals. The filter is then set up based on the filter data and the at least two signals are filtered correspondingly.</p> |
