Abstract
A video decoding method according to the present invention includes: decoding a bitstream, to obtain P quantization coefficients of a current region; determining, according to the P quantization coefficients, parity of a quantization coefficient whose parity is hidden of a first quantization coefficient; determining a target context model corresponding to the first quantization coefficient, and decoding the first quantization coefficient which is encoded based on context using the target context model, to obtain a decoded first quantization coefficient; and determining the second quantization coefficient according to the parity of the quantization coefficient whose parity is hidden and the decoded first quantization coefficient.
