Abstract
"MéTODO E APARELHO DE DECODIFICAçãO PARA DETECçãO DE MARCAS D<39>áGUA EM UM FLUXO DE BITS DE VìDEO COMPACTADO". Um codificador de vídeo (600), decodificador (700), e métodos (200, 300, 400, 500) para inserir marca d<39>água em conteúdo de vídeo, são revelados; o codificador incluindo uma unidade de quantização (630) para quantizar coeficientes do fluxo de bits de vídeo, e uma unidade de integração (635) em comunicação de sinal com a unidade de quantização para integrar bits da impressão digital em blocos do fluxo de bits de vídeo como uma função da paridade do número de coeficientes codificados no bloco; e o decodificador incluindo uma unidade de detecção (715) para detectar bits da impressão digital nos blocos do fluxo de bits de vídeo como uma função da paridade do número de coeficientes codificados no bloco, e uma unidade de quantização inversa (720) em comunicação de sinal com a unidade de detecção para quantização inversa dos coeficientes do fluxo de bits de vídeo.
