An apparatus for encoding to produce video data for a picture having a plurality of image blocks is disclosed. The video data include coded data for an image block of the plurality of image blocks and include at least one reference picture index. The apparatus comprises:
means for accessing (712) the image block and a single reference picture index for predicting the image block, the single reference picture index corresponding to a particular reference picture;
means for encoding (724) the image block using the particular reference picture corresponding to the single reference picture index and using a weighting factor, determined from a set of weighting factors, and corresponding to the single reference picture index,
wherein (714) the single reference picture index determines both the particular reference picture and the weighting factor, and each weighting factor in the set of weighting factors corresponds to a different particular reference picture. |
