Abstract

PARA UN SISTEMA DE TELEVISION DE COLOR COMPATIBLE CONVENIENTE PARA ALTA Y BAJA DEFINICION DE VISUALIZACION, SE TOMA UN SISTEMA MAC COMO EJEMPLO. AQUI SE UTILIZA UN DATV DIGITALMENTE ASISTIDO. PARA EFECTUAR UNA CODIFICACION REDUCIDA DEL ANCHO DE BANDA Y UNA DECODIFICACION REDUCIDA DEL ANCHO DE BANDA, SE UTILIZA, ADEMAS DEL CODIFICADOR Y DECODIFICADOR MAC, POR LO MENOS TRES CANALES DE SEÑAL DE PELICULA (PC) TENIENDO CADA UNO DE ELLOS UN PERIODO DE REGENERACION DE SEÑAL DE PELICULA DIFERENTE QUE ES IGUAL A, POR EJEMPLO, 80, 40 Y 20 MS QUE SE ACOPLA A TRAVES DE UN CIRCUITO MULTIPLEXADO DE DIVISION DE TIEMPO (MUX). CON LA DIVERSIDAD DE FUENTES DE SEÑALES DE PELICULAS, SE HA ENCONTRADO QUE DURANTE EL PROCESAMIENTO DE LA SEÑAL DE PELICULA LA DISTINCION ENTRE UNA MODALIDAD FILMICA (SW1, T40) Y UNA MODALIDAD NO FILMICA (SW1, T40) PROPORCIONA UNA RESOLUCION DE PELICULA DE ALTA DEFINICION SIGNIFICATIVAMENTE MEJORADA. EN EL DATV SE EXPRESA ESTA DISTINCION MEDIANTE UN BIT DE INFORMACION (FM). DURANTE LA MODALIDAD NO FILMICA (SW1, T20) SE MANTIENEN OPERATIVOS TRES CANALES DE LUMINISCENCIA EN Y (PC11, PC13 Y PC12) DE 80, 40 Y 20 MS Y DOS CANALES DE CROMINANCIA EN V Y EN U (PC21 Y PC22) DE 80 Y 20 MS. DURANTE LA MODALIDAD FILMICA (SW11, T40) SOLAMENTE SE MANTIENEN OPERATIVOS LOS CANALES EN Y (PC11 Y PC13) Y LOS CANALES EN V Y U (PC21 Y PC23) DE 80 Y 40 MS.
