Abstract:
A method, device, and computer program for motion vector prediction in scalable video encoder and decoder. The method concerns the process to determine motion information predictor in the enhancement layer of a scalable encoding scheme also known as motion derivation process. The method comprises a correction of the position in the reference layer used to pick-up the more relevant motion information available due to the compression scheme. Accordingly, motion information prediction is improved.
