Abstract

"SISTEMA DE VERIFICAçãO DE TRáFEGO" Trata-se de um método e aparelho para inserir um sinal de dados dentro de um sinal de áudio para produzir um sinal marcado. O método inclui remover uma faixa de freq³ências centralizada em uma freq³ência de entalhe pré determinada do sinal de áudio, formar de forma espectral o sinal de dados tal que ele absorve a forma e magnitude precisas do envelope do sinal de áudio na faixa removida, e inserir o sinal de dados formado na faixa removida do sinal de áudio. O método pode ser usado para identificar um segmento de áudio ou ele pode ser usado para codificar o sinal de áudio com outros dados desejados. O método da invenção torna o sinal de dados virtualmente inaudível para o ouvinte do segmento de áudio, porém forte o suficiente para superar o processamento severo do sinal de áudio.
