Abstract
A method of generating a prediction block and a device using same use a weighted-sum of an intra-prediction signal and an inter-prediction signal. The method includes: determining that a current block of the video data is to be encoded in a weighted-sum prediction mode; splitting the current block into two or more subblocks; determining, for each of the subblocks, a weight set including a first weight for an intra-prediction signal of the current block and a second weight for an inter-prediction signal of the current block, the subblocks having different weight sets; and determining a prediction block of the current block based on a weighted-sum of the intra-prediction signal and the inter-prediction signal, the weighted-sum being dependent on the weight set that is determined for each of the subblocks.
