Abstract
"MéTODO E PROCESSADOR DE CONTROLE DA REPRODUçãO DE UM SINAL DE áUDIO". Os aparelhos e os métodos que se conformam à presente invenção compreendem um método de controle da reprodução de um sinal de áudio através da análise de um sinal de 'closed caption' correspondente conjuntamente com a análise do sinal de áudio correspondente. O texto de objeção ou um outro texto especificado no sinal de 'closed caption' é identificado através de comparação com o texto censurável identificado pelo usuário. Com a identificação do texto censurável, o sinal de áudio é analisado para identificar a porção de áudio que corresponde ao texto censurável. Com a identificação da porção de áudio, o sinal de áudio pode ser controlado para emudecer o texto censurável audível.
