Abstract
"PROCESSO E ARRANJO PARA EMBUTIR DADOS SUPLEMENTARES EM UM SINAL DE INFORMAçãO, SINAL DE INFORMAçãO CODIFICADO POR UM CODIFICADOR, E, MEIO DE ARMAZENAMENTO" Um arranjo para embutir dados suplementares (por exemplo, uma filigrana W) em um sinal de informação (x). Em um modo de realização da invenção, o arranjo compreende um modulador sigma-delta convencional (20) para codificar um sinal de áudio (x) e meios de modificar (2) para substituir periodicamente um bit do sinal codificado (y) por um bit (w~ i~) da filigrana. Do mesmo modo, um padrão de sincronização (S) é embutido no sinal. Os bits de sincronização (s~ i~) são embutidos a uma distância menor do que bits de filigrana. De preferência, o padrão de sincronização é um padrão de bits contíguos que é tipicamente não gerado pelo codificador. Para o modulador sigma-delta, um tal padrão é uma fileira de uns seguida por uma fileira substancialmente igualmente longa de zeros, ou vice versa.
