Abstract

SE CONOCEN SISTEMAS QUE SE BASAN EN LA CODIFICACION DE VIDEO EN CAPAS, Y CODIGO DE DECODIFICACION DE VIDEO, CON INADECUADA EFICACIA, DEBIDO A QUE LA NUEVA IMAGEN DE ALTA RESOLUCION SE PREDICE CON UN MEDIO DE CONMUTACION PESENTE EN EL SISTEMA, BIEN SOBRE LA BASE DE LA IMAGEN DE ALTA RESOLUCION ANTERIOR, BIEN SOBRE LA BASE DE LA IMAGEN DE BAJA RESOLUCION INSTANTANEA. DE CONFORMIDAD CON LA INVENCION, DESIGNANDO EL MEDIO DE CONMUTACION PARA EL AJUSTE DE LA PROPORCION DE LA SEÑAL QUE REPRESENTA LA IMAGEN DE ALTA RESOLUCION PRECEDENTE Y LA SEÑAL QUE REPRESENTA LA IMAGEN DE BAJA RESOLUCION INSTANTANEA, Y ENTONCES AÑADIENDO AMBAS SEÑALES AJUSTADAS, SE OBTIENE UNA GANANCIA DE 3 DB EN LA PREDICCION CON LA PROPORCION CORRECTA, Y ESTO RESULTA EN UN PERFECCIONAMIENTO EN LA EFICACIA DE LA CODIFICACION.
