Title: Inter-component prediction
Inventor: TUNG NGUYEN
IPC: H04N19/136
Filed: 2019-04-03
Abstract: To promise increased coding efficiency over a broader range of multi-component picture content.SOLUTION: A second component signal relating to a second component of a multi-component picture is reconstructed from a spatially corresponding portion of a reconstructed first component signal and a correction signal derived from a data stream for the second component. By including the spatially corresponding portion of the reconstructed first component signal in the reconstruction of the second component signal, any remaining inter-component redundancies/correlations present despite a possibly a priori performed component space transformation, or present because of having been introduced by such a priori performed component space transformation, for example, may readily be removed by way of the inter-component redundancy/correlation reduction of the second component signal.SELECTED DRAWING: Figure 2
