Coding method, decoding method, and equipments for transform coefficients

摘要: Disclosed in the present invention are a coding method, decoding method and equipments for transform coefficients. The example, comprises following steps: coefficients of block according to preset scanning sequence, setting number each group, until last group block; storing acquired non-zero distribution, absolute values positive or negative signs coefficients; when is coded, stored distribution into code stream after acquired, together with acquired. It can improve efficiency decoding.
