==Original Abstract Submitted==

The present disclosure describes techniques for efficient coding of motion vectors developed for multi-hypothesis coding applications. According to these techniques, when coding hypotheses are developed, each having a motion vector identifying a source of prediction for a current pixel block, a motion vector for a first one of the coding hypotheses may be predicted from the motion vector of a second coding hypothesis. The first motion vector may be represented by coding a motion vector residual, which represents a difference between the developed motion vector for the first coding hypothesis and the predicted motion vector for the first coding hypothesis, and outputting the coded residual to a channel. In another embodiment, a motion vector residual may be generated for a motion vector of a first coding hypothesis, and the first motion vector and the motion vector residual may be used to predict a second motion vector and a predicted motion vector residual. The second hypothesis's motion vector may be coded as a difference between the motion vector, the predicted second motion vector, and the predicted motion vector residual. In a further embodiment, a single motion vector residual may be output for the motion vectors of two coding hypotheses representing a difference between the motion vector of one of the hypotheses and a predicted motion vector for that hypothesis.
