Abstract

An image in a digital video sequence comprising blocks of pixels is encoded and decoded. The encoding comprises a step of subtracting (1393) a prediction image (1391) from an original image (1310) to obtain a residual image (1394). The prediction image (1391) comprises a set of prediction units (1410 in fig. 14), each prediction unit being a best predictor according to a given criterion (13C) between predictors obtained by motion estimation (INTER) and predictors obtained using information from a corresponding base layer (1320) image (Intra BL, Base Mode). Corresponding decoding is also disclosed.
