Abstract

Un aparato de decodificación de video incluye: un divisor configurado para dividir una imagen en al menos un bloque; un pronosticador configurado para predecir una muestra actual al utilizar al menos uno de un valor obtenido al aplicar un primer peso a una primera muestra prevista antes que la muestra actual en un bloque actual y que es adyacente a la muestra actual en una dirección horizontal y un valor obtenido al aplicar un primer peso a una segunda muestra prevista antes que la muestra actual en el bloque actual y que es adyacente a la muestra actual en una dirección vertical; y un decodificador configurado para decodificar la imagen al utilizar un valor residual de la muestra actual obtenida de una corriente de bits y un valor de predicción de la muestra actual.
