Abstract

Un receptor adaptivo incluye un descodificador adaptivo (12) para proporcionar informacion de salida descodificada desde una señal de video codificada para transmision por satélite, terrestre o cable. El aparato incluye un descodificador adaptivo (50, 60) para proporcionar un primera salida descodificada como una funcion de un régimen de codificador seleccionada a partir de una pluralidad de regímenes de codigo. El aparato también incluye un desintercalador adaptivo (80, 85, 90) para desintercalar la primera salida descodificada de acuerdo con una funcion desintercaladora seleccionada entre una pluralidad de funciones desintercaladoras. Además, el aparato incluye un procesador de señales de salida (125) para procesar la informacion de salida desintercalada para proporcionar la informacion de salida descodificada. El desmodulador también puede incorporar un descodificador de error adaptivo (110) para detectar y corregir errores en la salida desintercalada. Además, un detector de calidad de señales puede proporcionar una estimacion del error en la informacion de salida descodificada. El aparato se configura automáticamente para ser compatible con el formato de la señal de video codificado como respuesta a la estimacion del error.
