Abstract

UN RECEPTOR/DECODIFICADOR DE TELEVISION INCLUYE ELEMENTOS (8) PARA DETECTAR QUE CANALES SE PUEDEN RECIBIR POR ESE RECEPTOR/DECODIFICADOR. UNA PRIMERA MEMORIA (12) ALMACENA LOS DATOS CON RELACION A TODOS LOS CANALES POSIBLES. UNA SEGUNDA MEMORIA (14) SE UTILIZA PARA ALMACENAR DATOS CON RELACION A LOS CANALES QUE PUEDE RECIBIR EL RECEPTOR/DECODIFICADOR. LA SEGUNDA MEMORIA SE CARGA SELECTIVAMENTE CON LOS DATOS DE LA PRIMERA MEMORIA DEPENDIENDO DE LOS CANALES QUE EL ELEMENTO DE DETECCION DETERMINE QUE EL RECEPTOR/DECODIFICADOR PUEDE RECIBIR. DE UNA PLURALIDAD DE BLOQUES DE BAJO RUIDO (LNB) EN UNA ANTENA PUEDE SELECCIONARSE UNO MEDIANTE UNA SEÑAL DE CONTROL QUE HACE QUE LA CORRIENTE SE APLIQUE SELECTIVAMENTE A UN LNB. SE PUEDE SELECCIONAR UNA PLURALIDAD DE OSCILADORES (60) EN UN LNB O EN UNA ANTENA QUE PROPORCIONAN UN GENERADOR DE FRECUENCIA (54) ACOPLADO A UN CONDUCTOR PARA LA SEÑAL DE LA ANTENA Y OPERABLE PARA PRODUCIR EN AL MENOS UNA SEÑAL DE FRECUENCIA EN RESPUESTA A UNA SEÑAL DE CONTROL. LAANTENA INCLUYE UN INTERRUPTOR (58) QUE CONECTA LOS OSCILADORES ENTRE SI DEPENDIENDO DE LA SEÑAL DE FRECUENCIA RECIBIDA.
