Abstract
UN METODO Y APARATO (10) PARA DETERMINAR EL CANAL DE UNA VARIEDAD DE CANALES PREDETERMINADOS A LOS CUALES SE SINTONIZA UN RECEPTOR (12) CONTROLADO A DISTANCIA. UN DISPOSITIVO TRANSMISOR DE ESPECTADOR (24) INCLUYE UN TECLADO (26) PARA RECIBIR LAS SELECCIONES QUE INTRODUCE EL ESPECTADOR Y UN TRANSMISOR REMOTO QUE TRANSMITE FRECUENCIA INFRARROJA, ULTRASONICA, RADIO U OTRAS SEÑALES DE CONTROL RADIADAS PARA CADA UNA DE LAS SELECCIONES DEL ESPECTADOR. UN DISPOSITIVO RECEPTOR (28) EN UN SISTEMA DE DETECCION DE CANAL (10) RECIBE UNA SEÑAL EN EL MEDIO DE TRANSMISION SELECCIONADO, E INMEDIATAMENTE SEÑALA UN DISPOSITIVO DE INTERFERENCIA (44) PARA INTERFERENCIA DE RADIODIFUSION QUE IMPIDE AL RECEPTOR CONTROLADO A DISTANCIA (12) QUE IDENTIFIQUE Y ACTUE SOBRE LA SEÑAL DE CONTROL TRANSMITIDA. EL DISPOSITIVO RECEPTOR (28) APLICA LA SEÑAL RECIBIDA A UN DISPOSITIVO PROCESADOR (30) QUE EJECUTA UN PROGRAMA ALMACENADO PARA DETERMINAR SI LA SEÑAL RECIBIDA CORRESPONDE A UNA SEÑAL DE CONTROL TRANSMITIDA DESDE EL DISPOSITIVO TRANSMISOR DEL ESPECTADOR (24) Y, SI ES ASI, PARA IDENTIFICAR EL CANAL AL CUAL SE VA A SINTONIZAR EL RECEPTOR SUPERVISADO (12) CONTROLADO A DISTANCIA. UN DISPOSITIVO DE MEMORIA ASOCIADO (52) SE USA PARA ALMACENAR LOS DATOS DE RECEPCION DEL CANAL IDENTIFICADO. EL DISPOSITIVO PROCESADOR (30) IDENTIFICA LA SELECCION DEL USUARIO Y O BIEN APLICA UNA SEÑAL DE CONTROL CORRESPONDIENTE A UN SEGUNDO DISPOSITIVO TRANSMISOR (48), EL CUAL TRANSMITE UNA SEÑAL DE CONTROL DE POTENCIA SUFICIENTE PARA SUPERAR LA INTERFERENCIA, O INDICA AL DISPOSITIVO DE INTERFERENCIA (44) QUE CESE LA RADIODIFUSION DE SEÑALES DE INTERFERENCIA. EN CUALQUIER CASO, EL RECEPTOR (12) CONTROLADO A DISTANCIA RECIBIRA Y EJECUTARA AHORA LA SELECCION DEL ESPECTADOR. EL DISPOSITIVO PROCESADOR (30) DIFUNDIRA PERIODICAMENTE UNA ORDEN AL RECEPTOR CONTROLADO A DISTANCIA (12) QUE CONTIENE LOS ULTIMOS DATOS DEL CANAL IDENTIFICADO PARA ASEGURAR QUE EL ESPECTADOR NO AJUSTE MANUALMENTE EL CANAL QUE SE ESTA VIENDO.
