Abstract
En un ejemplo, un método de decodificación de datos de video incluye seleccionar un modo de derivación de información de movimiento de entre una pluralidad de modos de derivación de información de movimiento para determinar información de movimiento para un bloque actual, donde cada modo de derivación de información de movimiento de la pluralidad comprende ejecutar una búsqueda de movimiento de un primer conjunto de datos de referencia que corresponde a un segundo conjunto de datos de referencia fuera del bloque actual, y donde la información de movimiento indica movimiento del bloque actual con relación a datos de video de referencia; el método también incluye determinar la información de movimiento para el bloque actual utilizando el modo de derivación de información de movimiento seleccionado; el método también incluye decodificar el bloque actual utilizando la información de movimiento determinada y sin decodificar elementos de sintaxis representativos de la información de movimiento.
