Abstract
LA PRESENTE INVENCION, SE REFIERE A UN SISTEMA PARA LA RECEPCION Y TRANSMISION DE SEÑALES DE TELEVISION CODIFICADAS, DONDE LA SEÑAL DE TELEVISION ES REGISTRADA A FIN DE NO PODER SER RECIBIDA NI REPRODUCIDA POR LOS MEDIOS NORMALES DE LOS RECEPTORES DE TELEVISION, SI NO UNICAMENTE POR RECEPTORES EQUIPADOS CON UN DECODIFICADOR DETERMINADO, DISPONIENDO DICHO DECODIFICADOR DE UN CIRCUITO DE CONTROL QUE RECIBE PERIODICAMENTE UN CODIGO SECRETO TELEFONICAMENTE MEDIANTE UNA COMPUTADORA CENTRAL. EL CODIGO SECRETO, ES INDISPENSABLE PARA LA OPERACION DE DECODIFICADO. LAS PRINCIPALES CARACTERISTICAS DE LA INVENCION, CONSISTEN EN EL HECHO DE QUE EL MENCIONADO CODIGO SECRETO ES TRANSMITIDO MEDIANTE UN SISTEMA DE CIFRADO A INTERVALOS VARIABLES Y, TAMBIEN EN LA CIRCUNSTANCIA DE QUE TAL SISTEMA DISPONE QUE, EL CIRCUITO DE CONTROL, EL CIRCUITO DE MEMORIA ASOCIADA AL MISMO, UN MODEM TELEFONICO (DISPOSITIVO QUE TRANSFORMA LAS SEÑALES DE SALIDA PARA SU TRANSMISION, VIA TELEFONICA O TELEGRAFICA), Y UNA BATERIA ELECTRONICA ESTEN IMPRESOS EN UNA TARJETA EXTRAIBLE DEL DECODIFICADOR Y ENLAZABLE CON LA LINEA TELEFONICA, Y QUE DICHO DECODIFICADOR SE PERSONALICE CON UN NUMERO DE IDENTIFICACION.
