Abstract

Se proporciona un método de codificación de video con el cual pueden ser optimizadas la eficiencia de predicción y la eficiencia de codificación, además de un dispositivo de decodificación de video. Un dispositivo de codificación de video (100) codifica los datos de video mediante la realización de una compensación de movimiento con una precisión de píxel de decima mediante la utilización de un filtro adaptivo de interpolación para el cálculo de un valor de píxel de un píxel de decima que realiza la interpolación entre píxeles de numero entero que configuran una imagen de entrada incluida en los datos de video. El dispositivo de codificación de video (100) comprende una unidad de predicción de compensación de movimiento (160) que regula la característica de filtro del filtro adaptivo de interpolación para cada unidad predeterminada de proceso, también determina la pluralidad de coeficientes de filtro del filtro adaptivo de interpolación que tenga las características reguladas de filtro para cada ubicación de los píxeles de decima que son relacionados con el píxel de numero entero y efectúa la compensación de movimiento con la precisión del píxel de decima mediante la aplicación del filtro adaptivo de interpolación que tenga la pluralidad de coeficientes de filtro decidida en la imagen de entrada, un sustractor (110) que genera un error de predicción mediante la realización de la sustracción entre la imagen de predicción generada por la compensación de movimiento y la imagen de entrada y una unidad de codificación de entropía (190) que codifica el error de predicción.
