Abstract
Un método ejemplar de procesamiento de video incluye realizar una conversión entre un bloque de un video y un flujo de bits del video. El flujo de bits se ajusta a una regla de formateo que especifica que un tamaño de una región de estimación de fusión (MER) se indica en el flujo de bits y el tamaño de la MER se basa en una dimensión de una unidad de video. La MER comprende una región utilizada para derivar un candidato de movimiento para la conversión.
