In a high-efficiency encoder which performs motion-compensation prediction, an intra-field is set every n fields. The presence of a scene change is detected. When a scene change occurs, a reference picture of motion-compensation prediction is switched, or the field immediately after the scene change...http://www.google.fr/patents/US7688892?utm_source=gb-gplus-shareBrevet US7688892 - High efficiency encoder and video information recording/reproducing apparatus
