Claim Text:
1. An audio or video decoder for decoding an encoded multi-channel audio or video signal, the encoded multi-channel audio or video signal comprising an encoded first combination signal, an encoded prediction residual signal and prediction information, comprising: a signal decoder for decoding the encoded first combination signal to acquire a decoded first combination signal, and for decoding the encoded residual signal to acquire a decoded residual signal; and a decoder calculator for calculating a decoded multi-channel signal comprising a decoded first channel signal, and a decoded second channel signal using the decoded residual signal, the prediction information, the decoded first combination signal and a prediction direction indicator indicating a prediction direction associated with the decoded prediction residual signal, so that the decoded first channel signal and the decoded second channel signal are at least approximations of a first channel signal and a second channel signal of a multi-channel signal, wherein the decoder calculator is configured for using a first calculation rule for calculating the decoded multi-channel signal in case of a first state of the prediction direction indicator and for using a second different calculation rule for calculating the decoded multi-channel signal in case of a second different state of the prediction direction indicator.
