Abstract

La presente invención se refiere a un método para identificar por lo menos un Contenido dentro de una Corriente de Datos, el Contenido es necesitado por una Aplicación determinada que se ejecuta en un Dispositivo de Prueba. De acuerdo con la invención, se propone un método para identificar por lo menos un Contenido dentro de una Corriente de Datos, el contenido es necesitado por una Aplicación determinada que se ejecuta en un dispositivo de prueba, este método comprende los pasos que consisten en: a) capturar por lo menos una Corriente de Datos, b) analizar y filtrar la Corriente de Datos al: c) aislar por lo menos una Corriente de Prueba de la Corriente de Datos y deshabilitar las otras sub-corrientes, empleando la Corriente de Prueba en la Aplicación con el fin de producir una salida (R), d) aplicar la salida a un Comparador (comp), el comparador recibe una referencia (R´) y determinar por medio del comparador una distancia (D) entre la salida de la Aplicación (R) y la referencia (R´), en caso de que la distancia (D) sea inferior a un nivel predeterminado (L) , repetir el paso c) con una nueva Corriente de Prueba seleccionada entre la Corriente de Prueba previa, la nueva Corriente de Prueba es un subconjunto de la Corriente de Prueba previa, en caso de que la distancia (D) sea superior o igual a un segundo nivel predefinido (L2), repetir el paso c) al seleccionar una Corriente de Prueba diferente de la Corriente de Datos no empleada previamente en la Aplicación.
