Abstract
The embodiments of the present application provide a coefficient decoding method, an electronic device and a storage medium. The method includes: parsing a code stream to obtain coefficient group information of a unit to be decoded, where coefficients of the unit to be decoded are divided into one or more coefficient groups, each of the coefficient groups includes one or more coefficient codes, the coefficient codes in a same coefficient group are fixed-length codes with a same coding length, the coefficient groups include a first coefficient group, and the coefficient group information includes one or more boundary symbols of the first coefficient group; parsing one or more coefficient codes in the first coefficient group into one or more coefficient values; and determining whether the coefficient values in the first coefficient group are positive or negative according to the boundary symbols
