Abstract
A method and apparatus for video frame interpolation using a current video frame, at least one previous video frame, and a set of transmitted motion vectors is described. A first set of motion vectors is created as a function of the set of transmitted motion vectors. An intermediated video frame is identified, where the intermediate video frame having a plurality of non-overlapping blocks. Each non-overlapping block is assigned with at least one motion vector chosen from the first set of motion vectors to create a set of assigned motion vectors. Then, a second set of motion vectors is created as a function of the assigned set of motion vectors. A video frame is generated using the second set of motion vectors.
