Abstract

SE PRESENTA UN RECEPTOR DE TELEVISION QUE INCLUYE UN CIRCUITO DE BUSQUEDA DE SINTONIZACION PARA EXPLORAR AUTOMATICAMENTE LOS DATOS DE SINTONIZACION DE LOS PROGRAMAS DE TELEVISION EN UNA BANDA DE FRECUENCIA DE RECEPCION DE RF TV DESPUES DE UNA SEÑAL DE ACTIVACION DE LA BUSQUEDA, UN DISPOSITIVO DE SINTONIZACION PARA SINTONIZAR EL RECEPTOR DE TV A UN PROGRAMA DE TV HALLADO POR EL CIRCUITO DE BUSQUEDA DE SINTONIZACION, Y UN DISPOSITIVO DE PROGRAMACION PRESELECCIONADA PARA ALMACENAR MANUALMENTE DICHOS DATOS DE SINTONIZACION EN UNA MEMORIA DE SINTONIZACION EN UN LUGAR A PARTIR DEL QUE LOS DATOS DE SINTONIZACION SON DIRECCIONABLES HACIENDO FUNCIONAR UNA TECLA DE PRESELECCION DE PROGRAMA. PARA LA PROGRAMACION SIMPLE DE LAS TECLAS DE PRESELECCION LOS DATOS DE SINTONIZACION HALLADOS POR EL CIRCUITO DE BUSQUEDA DE SINTONIZACION SE ALMACENAN AUTOMATICAMENTE EN UNA MEMORIA INTERMEDIA, LA CUAL, DESPUES DE LA INICIALIZACION DEL DISPOSITIVO PROGRAMADOR DE PRESELECCION, SUMINISTRA LOS DATOS DE SINTONIZACIONAL DISPOSITIVO DE SINTONIZACION PARA SINTONIZAR EL RECEPTOR DE TV E IDENTIFICAR EL PROGRAMA DE TV QUE SE CORRESPONDE CON LOS DATOS DE SINTONIZACION, TODO ELLOS SEGUIDO DE DICHO ALMACENAMIENTO MANUAL.
