Abstract
The coding efficiency of a multi-component picture or video coding concept is improved by reconstructing a third component signal relating to a third component of the multi-component video using inter-component prediction from both a reconstructed first component signal and a reconstructed second component signal.

A decoder, comprising:
- a processor configured to execute a program for decoding a multi-component video based on operations including:
- reconstructing a first component signal relating to a first component of the multi-component video from a data stream;
- reconstructing a second component signal relating to a second component of the multi-component picture from the data stream;
- determining weights based on inter-component prediction (ICP) parameter signalization in the data stream by decoding a sign and an absolute value related to the weights;
- and
- reconstructing a third component signal relating to a third component of the multi-component video based on the ICP associated with the reconstructed first component signal and the reconstructed second component signal, wherein the inter-component prediction is performed using linear prediction based on the weights, which indicate contributions of the reconstructed first component signal and the reconstructed second component signal to the inter-component prediction.
