Abstract
Provided are a method for determining a prediction direction, a decoder and a computer storage medium. The method is implemented by a decoder. The method includes that: a Direct Mode (DM) in a chroma intra prediction mode of a block to be decoded is acquired (S); and an index number of a prediction direction in a DM derived mode is determined based on an offset N and an index number M of a prediction direction in the DM to determine the DM derived mode (S).
