Abstract
resumo patente de invenção: "correção aperfeiçoada de perda de quadro na decodificação de um sinal". a invenção refere-se a um processamento de sinal, o sinal comportando uma sucessão de amostras repartidas em quadros sucessivos. o processamento é utilizado durante uma decodificação desse sinal para substituir pelo menos um quadro de sinal perdido na decodificação, e comporta, em particular, as etapas: a) pesquisa (s3) , em um sinal válido disponível na decodificação, de um segmento de sinal, de duração correspondente a um período determinado em função desse sinal válido, b) análise espectral do segmento (s4), para uma determinação de componentes espectrais do segmento, c) síntese (s6) de pelo menos um quadro de substituição do quadro perdido, por construção de um sinal de síntese, a partir de uma parte pelo menos dos componentes espectrais.
