Abstract
The techniques described herein relate to methods, apparatus, and computer readable media configured to receive compressed video data, wherein the compressed video data is related to a set of frames. A decoder-side predictor refinement technique is used to calculate a new motion vector for a current frame from the set of frames, wherein the new motion vector estimates motion for the current frame based on one or more reference frames. An existing motion vector associated with a different frame from a motion vector buffer is retrieved. The new motion vector is calculated based on the existing motion vector using a decoder-side motion vector prediction technique, such that the existing motion vector is in the motion vector buffer after calculating the new motion vector.
