Original Abstract Submitted

a picture decoding method performed by a decoding device according to an embodiment of the present disclosure comprises the steps of: deriving a context index for a split flag syntax element on the basis of split availability information of a current block; determining a context model on the basis of the derived context index; decoding a value of the split flag syntax element on the basis of a cabac, using the determined context model; deriving a current coding unit from the current block on the basis of the value of the split flag syntax element; deriving a predicted block on the basis of inter prediction or intra prediction for the current coding unit; and generating a reconstructed block on the basis of the predicted block.
