Abstract

"MéTODO E ARRANJO PARA AJUSTAR UM SINAL DE DADOS SUPLEMENTARES PARA SER EMBUTIDO EM UM SINAL DE INFORMAçãO, DISPOSITIVO PARA EMBUTIR UM SINAL DE DADOS SUPLEMENTARES EM UM SINAL DE INFORMAçãO, SINAL DE INFORMAçãO, E, MEIO DE ARMAZENAGEM". é mostrado um método para ajustar um sinal de dados suplementares (wm(n)) para ser embutido em um sinal de informação (x(n)), por exemplo um sinal de áudio. O método compreende as etapas de determinar (107) uma magnitude relativa (g(n)) de uma primeira função de propriedade (M~ x~(n)) do sinal de informação rateado ao longo de uma região de um tamanho predeterminado e uma segunda função de propriedade (M~ wm~(n)) do sinal de dados suplementares, rateado sobre a citada região; e ajustar (407) o sinal de dados suplementares de acordo com a magnitude relativa determinada.
