Abstract
A method for motion vector prediction for a current block, the current block having a set of neighboring blocks that includes blocks that do not have an associated motion vector, is disclosed. The method including deriving a candidate motion vector for each block in the set of neighboring blocks that does not have an associated motion vector; and using the candidate motion vector for each block in the set of neighboring blocks that does not have the associated motion vector to predict a current motion vector for the current block. An apparatus for performing the method is also disclosed.
