Abstract

A decoding method, an encoding method, a decoder and an encoder are provided. The decoding method includes the following step: decoding the syntax element for specifying a maximum geometry tree size. The step of decoding the syntax element including the following steps: reading an encoded value of the syntax element for specifying the maximum geometry tree size from the bitstream; adding the encoded value of the syntax element for specifying the maximum geometry tree size to a preset integer to obtain a first code; and left-shifting the number 1 by a result of the encoded value of the syntax element for specifying the maximum geometry tree size plus the preset integer to obtain a decoded value of the maximum geometry tree size.
