Abstract:
A method and apparatus are provided for motion estimation using combined reference bi-prediction. The apparatus includes an encoder (200) for encoding a multi-prediction picture from a combination of two or more reference pictures by respectively predicting a motion vector for a particular one of the two or more reference pictures in a motion estimation process while initializing motion vectors for remaining ones of the two or more reference pictures to a predefined value for use by the motion estimation process.
