Abstract
The present application provides a video encoding/decoding method and apparatus. The method includes: obtaining, by a decoding end, a code stream of a unit to be decoded; determining a scanning manner and a grouping manner of the unit to be decoded, and an coding manner corresponding to each group; decoding according to the coding manner of each group to obtain one or more coefficient blocks corresponding to the unit to be decoded; and recovering one or more coefficients in each of the coefficient blocks in each group one by one according to the scanning manner of the unit to be decoded to obtain one or more reconstructed data blocks corresponding to the unit to be decoded.
