1. A method of decoding video data, the method comprising: determining a first co-located reference picture for generating a first temporal motion vector predictor candidate for predicting a motion vector of a current block; determining a second co-located reference picture for generating a second temporal motion vector predictor candidate for predicting the motion vector of the current block; determining a motion vector predictor candidate list that includes at least one of the first temporal motion vector predictor candidate and the second temporal motion vector predictor candidate; selecting a motion vector predictor from the motion vector predictor candidate list; and decoding the motion vector of the current block relative to the selected motion vector predictor.
