Abstract

La senal de television (TS) comprendiendo datos de cuadro (P1), cuya senal de television además comprende una simiente predeterminada (S1), utilizable para iniciar un generador seudo-aleatorio que produce una secuencia determinada de valores aleatorios a ser usados para agregar ruido a los datos de cuadro, resuelve el problema de busqueda arbitraria para distintos aparatos receptores, cada uno con su propio ruido seudo-aleatorio generado.
