Title: METHOD AND APPARATUS FOR ENCODING/DECODING MULTI-LAYER VIDEO USING WEIGHTED PREDICTION
Abstract:
A method and apparatus effectively encode multiple layers using interlayer information in a multi-layered video codec. The method includes reading information concerning the low layer picture, calculating weighting factors using the information concerning the low layer picture, calculating a weighted sum of reference pictures for the current picture using the weighting factors and generating a predicted picture for the current picture, and encoding a difference between the current picture and the predicted picture.
