Реферат: The techniques described herein relate to methods, apparatus, and computer readable media configured to determine motion vectors. The techniques relate to both encoders and decoders. For example, a decoder receives compressed video data related to a set of frames. The decoder calculates, using a decoder-side predictor refinement technique, 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. The calculation includes retrieving a first motion vector associated with the current frame, executing a first portion of the decoding process using the first motion vector, retrieving a second motion vector associated with the current frame that is different than the first motion vector, and executing a second portion of the decoding process using the second motion vector.
