    Abstract: PURPOSE: A method and an apparatus for encoding and decoding a video is provided to use prediction information of an upper level coding unit (CU) for prediction of a current CU, thereby increasing an encoding speed. CONSTITUTION: An encoder determines whether or not to use prediction information of an upper level CU for inter-prediction for current CU based on an inter-prediction result of the upper level CU (S510). The encoder performs inter-prediction for the current CU based on a result of the determination. The encoder determines an encoding mode for the current CU based on a result of the inter-prediction (S520). The encoder determines, using the determined encoding mode, determines a form and a size for splitting a largest coding unit (LCU) in which the current CU is included (S530). The encoder encodes an input video based on the determined form and size of the LCU. [Reference numerals] (S510) Determine whether or not to use prediction information of an upper level CU; (S520) Determine an optimal mode for the current CU; (S530) Determine whether or not to divide a present CU
