    Abstract: A method of decoding an image includes performing entropy-decoding to obtain quantized transformation coefficients of at least one transformation unit in a coding unit of the image, determining a prediction mode of at least one prediction unit in the coding unit from information indicating a prediction mode for the at least one prediction unit, when the prediction mode is determined to be an inter prediction mode, not in an intra prediction mode, determining a size of the at least one transformation unit in the coding unit regardless of a size of the at least one prediction unit in the coding unit, performing inverse-quantization and inverse-transformation on the quantized transformation coefficients of the at least one transformation unit to obtain residuals, and performing inter prediction for at least one prediction unit in the coding unit to generate a predictor and restoring the image by using the residuals and the predictor.

    Abstract: An apparatus for decoding a video including a processor which determines coding units having a hierarchical structure being data units in which the encoded image is decoded, and sub-units for predicting the coding units, by using information that indicates division shapes of the coding units and information about prediction units of the coding units, parsed from a received bitstream of a encoded image, wherein the sub-units comprise partitions obtained by splitting at least one of a height and a width of the coding units according to at least one of a symmetric ratio and an asymmetric ratio, and a decoder which reconstructs the image by performing decoding including motion compensation using the partitions for the coding units, using the encoding information parsed from the received bitstream, wherein the coding units having the hierarchical structure comprise coding units of coded depths split hierarchically according to the coded depths and independently from neighboring coding units.
