The MPEG-4 video standard includes a predictive coding scheme. When a scene-cut occurs in the sequence processed by said coding scheme, the first video object plane (VOP) which follows it is coded as an I-VOP, instead of predicting it from the previous VOP, completely different. In case of temporal scalability, when the scene-cut occurs between two VOPs of the enhancement layer, specific rules for selecting the temporal reference(s) during the prediction operations in said enhancement layer are defined.
