Claim 0:
1. A method of performing motion vector prediction for video data, the method comprising:
performing bi-prediction according to a first mode of bi-prediction, wherein the first mode allows only bi-prediction;
for the first mode of bi-prediction, performing inter prediction by:
inferring an index value for a first reference picture list;
generating a first motion vector based on a first signaled index value indicating a first motion vector predictor and a signaled value indicating a first motion vector difference value;
inferring an index value for a second reference picture list; and
generating a second motion vector based on a second signaled index value indicating a second motion vector predictor and a second motion vector difference value, wherein the second motion vector difference value is a scaled version of the first motion vector difference value, and

wherein a resolution of the first motion vector difference value and the second motion vector difference value are adjusted according to a signaled motion vector difference resolution index value.
