Title:
SYSTEM AND METHOD FOR IMPROVING COMBINED INTER AND INTRA PREDICTION
Document Type and Number:
Japanese Patent JP2022172057
Kind Code:
A
Abstract:
To provide a method for improving the efficiency of syntax signaling of merge related modes and a storage medium.SOLUTION: A method for video coding, a method for generating combined inter and intra prediction (CIIP), includes obtaining a first reference picture and a second reference picture associated with a current prediction block, generating a first prediction L0 based on a first motion vector MV0 from the current prediction block to a reference block in the first reference picture, generating a second prediction L1 based on a second motion vector MV1 from the current prediction block to a reference block in the second reference picture, determining whether a bidirectional optical flow (BDOF) operation is applied, and calculating a bi-prediction of the current prediction block based on the first prediction L0 and the second prediction L1 and first gradient values and second gradient values.SELECTED DRAWING: Figure 3
