1. A video decoder comprising:
a first decoder configured for reconstructing, using a processor, a base layer signal from a coded data stream to obtain a reconstructed base layer signal; and
a second decoder configured for reconstructing, using a processor, an enhancement layer signal, the reconstructing comprising:
predicting, based on a reconstructed portion of the enhancement layer signal, a current portion of the enhancement layer signal to obtain an enhancement layer internal signal,
obtaining an inter-layer prediction signal associated with the current portion of the enhancement layer signal based on the reconstructed base layer signal,
extracting, from the coded data stream, weighting parameters for the inter-layer prediction signal and the enhancement layer internal prediction signal, wherein the weighting parameters are encoded into the data stream by an encoder,
determining a weighted average of the inter-layer prediction signal and the enhancement layer internal signal to obtain an enhancement layer prediction signal based on the weighting parameters, each of the weighting parameters indicating a respective contribution of the inter-layer prediction signal and the enhancement layer internal signal to obtain the enhancement layer prediction signal, and
predictively reconstructing the enhancement layer signal based on the enhancement layer prediction signal.
