Abstract

LA PRESENTE INVENCION SE REFIERE A UN SISTEMA PARA LA RECEPCION DE SEÑALES DE TELEVISION CODIFICADAS, EN EL QUE LA SEÑAL DE TELEVISION SE CODIFICA DE MANERA QUE NO PUEDE SER RECIBIDA Y REPRODUCIDA DE MANERA NORMAL POR RECEPTORES DE TELEVISION NORMALES, SINO SOLAMENTE POR RECEPTORES EQUIPADOS CON UN DECODIFICADOR APROPIADO; LA PRINCIPAL CARACTERISTICA DE LA INVENCION CONSISTE EN EL HECHO DE QUE EL SISTEMA TIENE UN DECODIFICADOR A CONECTAR A UN RECEPTOR NORMAL DE SEÑALES DE TELEVISION, QUE DICHO DECODIFICADOR ESTA EQUIPADO CON UN DISPOSITIVO PARA DETECTAR LA PRESENCIA DE UN USUARIO Y/O DE DICHO RECEPTOR, Y QUE DICHO DECODIFICADOR NO SE ACTIVA EN CASO DE QUE TAL PRESENCIA NO SE DETECTE.
