Abstract

Un dispositivo de cómputo lleva a cabo un método de decodificación de datos de video determinando una imagen co-ubicada de la unidad de codificación actual; ubicar un bloque adyacente espacial de la unidad de codificación actual que corresponde a la imagen co-ubicada; determinar un vector de desplazamiento de movimiento para la unidad de codificación actual de uno o más vectores de movimiento asociados con el bloque adyacente espacial de acuerdo con un orden predefinido fijo; y reconstruir un vector de movimiento temporal basado en sub-bloque para un sub-bloque respectivo de una pluralidad de sub-bloques en la unidad de codificación actual de un sub-bloque correspondiente en la imagen co-ubicada con base en el vector de desplazamiento de movimiento.
