METHOD FOR GENERATING PREDICTION BLOCK BY USING WEIGHTED-SUM OF INTRA PREDICTION SIGNAL AND INTER PREDICTION SIGNAL, AND DEVICE USING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18233228 titled 'METHOD FOR GENERATING PREDICTION BLOCK BY USING WEIGHTED-SUM OF INTRA PREDICTION SIGNAL AND INTER PREDICTION SIGNAL, AND DEVICE USING SAME

Simplified Explanation

The patent application describes a method and device for generating a prediction block in video encoding.

• The method involves using a weighted-sum of an intra-prediction signal and an inter-prediction signal.
• The current block of video data is split into two or more subblocks.
• Each subblock is assigned a weight set, which includes a first weight for the intra-prediction signal and a second weight for the inter-prediction signal.
• The weight sets for the subblocks can be different.
• The prediction block of the current block is determined based on a weighted-sum of the intra-prediction signal and the inter-prediction signal.
• The specific weighted-sum used depends on the weight set assigned to each subblock.

Original Abstract Submitted

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.
