Claim One:
1. A method of decoding video, the method comprising: receiving, by a decoding apparatus, a bitstream including information on an inter prediction type and information on a residual sample, wherein the information on the inter prediction type indicates whether list0 prediction, list1 prediction or bi-prediction is used as the inter prediction type for to a current prediction unit; deriving, by the decoding apparatus, a bin string of the information on the inter prediction type; deriving, by the decoding apparatus, a value of the information on the inter prediction type based on the bin string; determining, by the decoding apparatus, the inter prediction type for the current prediction unit based on the value of the information on the inter prediction type; deriving, by the decoding apparatus, a prediction sample of the current prediction unit based on the inter prediction type; deriving, by the decoding apparatus, the residual sample based on the information on the residual sample; and generating, by the decoding apparatus, a reconstructed sample based on the prediction sample and the residual sample, wherein whether the bi-prediction is not available for the current prediction unit is determined based on a size of the current prediction unit, wherein the current prediction unit is derived from a current coding unit based on a partition mode, and wherein when the current coding unit has an 8×8 size and the partition mode is 2N×N or N×2N, the bi-prediction is not available for the current prediction unit.
