Abstract

UN DESCODIFICADOR PARA DESCODIFICAR SEÑALES DE VIDEO CODIFICADAS QUE CONSTA DE UNA CAPA BASE Y DE UNA CAPA DE REFUERZO QUE INCLUYE UN DETECTOR DE PERDIDA DE CELDAS (66) PARA DETECTAR SI FALTAN CELDAS EN LA CAPA DE REFUERZO. CUANDO OCURRE ESTO, EL DATO DE AUMENTO DE LA SEÑAL DE VIDEO INMEDIATAMENTE ANTERIOR, DESPLAZADO POR EL DESPLAZADOR (64) SEGUN LOS VECTORES DE MOVIMIENTO ACTUALES, PROPORCIONA UNOS DATOS DE INTERPOLACION CORRESPONDIENTES A LAS CELULAS QUE FALTAN. EL DATO DE INTERPOLACION SE AÑADE A LA CAPA BASE DESCODIFICADA SEGUN LO QUE INDIQUE EL SUMADOR (52). EL DATO DE AUMENTO SE OBTIENE RESTANDO LA SEÑAL DE VIDEO BASE INMEDIATAMENTE ANTERIOR, ALMACENADA EN LA MEMORIA DE IMAGENES (50), DE LA SEÑAL DE VIDEO DESCODIFICADA INMEDIATAMENTE ANTERIOR, ALMACENADA EN LA MEMORIA DE IMAGENES (60), SEGUN LO INDIQUE EL RESTADOR (62).
