Abstract
Un codificador de video puede incluir una imagen actual y una imagen de referencia en una lista de imágenes de referencia; el codificador de video puede determinar un bloque co-ubicado de la imagen de referencia; el bloque co-ubicado está co-ubicado con un bloque actual de la imagen actual; además, el codificador de video deriva un predictor de vector de movimiento temporal a partir del bloque co-ubicado y puede determinar que el predictor de vector de movimiento temporal tiene una precisión de sub-píxel; el codificador de video puede desplazar a la derecha el predictor de vector de movimiento temporal que se determina que tiene la precisión de sub-píxel; además, el codificador dé video puede determinar, con base en el predictor de vector de movimiento temporal desplazado a la derecha, un bloque predictivo dentro de la imagen actual.
