Motion graphics keying in the compressed domain may be accomplished by receiving a compressed video stream comprising one or more source macrob locks, receiving a keyed graphics stream, determining which of the one or more source macrob locks overlaps with the keyed graphics stream, decoding only the one or more overlapping macroblocks to create one or more decoded macroblocks, combining the keyed graphics stream with the one or more decoded macroblocks to create a composited video stream, encoding the composited video stream to create an encoded composited video stream, and restoring the encoded composited video stream in the compressed video stream in place of the one or more overlapping macroblocks.

On peut effectuer le codage de graphiques animés dans le domaine compressé en recevant un flux vidéo compressé comprenant une ou plusieurs verrous de macrobloc source, en recevant un flux de graphiques codés, en déterminant lequel ou lesquels des verrous de macrobloc source chevauchent le flux de graphiques codés, en décodant uniquement le ou les macroblocs chevauchant de façon à créer un ou plusieurs macroblocs décodés, en combinant le flux de graphiques codés avec le ou les macroblocs décodés de façon à créer un flux vidéo composite, en codant ce flux vidéo composite de façon à créer un flux vidéo composite codé, et en restaurant ce flux vidéo composite codé dans le flux vidéo compressé à la place du ou des macroblocs chevauchant.
