Abstract

RESUMEN En un ejemplo, un método para decodificar datos de video incluye seleccionar un modo de derivación de información de movimiento de una pluralidad de modos de derivación de información de movimiento para determinar la información de movimiento para un bloque actual, en donde cada modo de derivación de información de movimiento de la pluralidad comprende realizar una búsqueda de movimiento para un primer conjunto de datos de referencia que corresponde a un segundo conjunto de datos de referencia fuera del bloque actual, y en donde la información de movimiento indica el movimiento del bloque actual con respecto a los datos de video de referencia. El método también incluye determinar la información de movimiento para el bloque actual usando el modo de derivación de información de movimiento seleccionado. El método también incluye decodificar el bloque actual usando la información de movimiento determinada y sin decodificar los elementos sintácticos representativos de la información de movimiento.
