Abstract

Un método de predicción de vector de movimiento temporal basada en subbloques se realiza en un dispositivo informático. El dispositivo informático adquiere un flujo de bits de video que incluye datos asociados con múltiples imágenes codificadas. Mientras decodifica una imagen actual en el flujo de bits de video, el dispositivo informático selecciona, de acuerdo con elementos de sintaxis señalados en el flujo de bits de video, una imagen de referencia como una imagen intercalada de la imagen actual, y determina un cambio de movimiento entre la imagen intercalada y la imagen actual a partir de la información de movimiento de los bloques espacialmente cercanos de una unidad de codificación actual (CU) de acuerdo con un orden fijo. Después, el dispositivo informático separa la CU actual en múltiples sub-CU, obtiene un predictor de vector de movimiento temporal para cada sub-CU a partir del cambio de movimiento y la información de movimiento de un bloque en la imagen intercalada que corresponde a un subbloque respectivo de la imagen actual y decodifica la CU actual de acuerdo con los predictores de vector de movimiento temporal.
