Title:

AN ENCODER, A DECODER AND CORRESPONDING METHODS FOR INTRA PREDICTION

Document Type and Number:

WIPO Patent Application WO/2020/192629

Kind Code:

A1

Abstract:

Devices and methods for Intra prediction are provided. The method includes: obtaining a value of an indication information of a current block. When the value of the indication information indicates the intra prediction mode of the current block is not comprised in the set of most probable modes, deriving the intra prediction mode IntraPredModeY [xCb] [yCb] of the current block by the following ordered steps: i. IntraPredModeY [xCb] [yCb] is set equal to intra_luma_mpm_remainder [xCb] [yCb], ii. The value of IntraPredModeY [xCb] [yCb] is incremented by one. The method can improve the efficiency to determine the intra prediction mode of the current block.
