A video encoder (100) can transform an incoming sequence of uncompressed pictures into compressed pictures, which may be predictive inter-picture coded pictures (108), bidirectionally inter-picture coded pictures (110) or intra-picture coded pictures (106). These pictures are called, P-pictures, B-pictures, respectively I- pictures. Since B-pictures use I- pictures and P-pictures as predictions, they have to be coded later. This requires re-ordering the picture sequence. The video encoder (100) comprises a reorder picture pool (104) to reorder compressed pictures.
