Claim Text:
1. A method of decoding video by using deblocking filtering, the method comprising: hierarchically splitting a maximum coding unit among one or more maximum coding units into one or more coding units based on split information; determining one or more prediction units in a coding unit among the one or more coding units using partition type information, wherein the partition type information indicates one of a symmetric type and an asymmetric type; determining one or more transform units in the coding unit using size information of a transform unit, wherein the transform unit among the one or more transform units is rectangular with a horizontal size and a vertical size indicated by the size information; performing prediction on a prediction unit among the one or more prediction units in the coding unit and inverse-transformation on the transform unit in the coding unit, in order to generate a reconstructed coding unit; when a boundary included in the reconstructed coding unit corresponds to at least one of a boundary of the prediction unit and a boundary of the transform unit, determining a boundary strength for the boundary included in the reconstructed coding unit based on at least one of non-zero transformation coefficients, prediction mode, a motion vector, and a reference index; and performing deblocking filtering on neighboring pixels according to the boundary strength, in order to generate a filtered coding unit including deblocking-filtered pixels, wherein:
