Abstract

An interframe prediction method, applied to a decoder. The method comprises: parsing a code stream and obtaining a weight deriving mode of the current block; on the basis of the weight deriving mode of the current block, constructing a new motion information candidate list; and on the basis of the new motion information candidate list, determining an interframe predicted value of the current block. Provided are a decoder, an encoder, and a computer storage medium.
