Abstract

"ESQUEMA DE MARCAçãO D'áGUA PARA VìDEO DIGITAL". Dados a serem impressos sobre o valor médio de uma parcela de crominância de um bloco, são replicados pelo menos uma vez. O original e cada réplica são impressos em blocos na mesma posição de bloco de quadros separados. Os quadros que têm blocos posicionados iguais que estão portando os mesmos dados são considerados como sendo um grupo. Blocos específicos do quadro poderão ser embutidos com uma seq³ência de dados conhecida particular em vez de dados do usuário. Cada grupo poderá empregar uma seq³ência conhecida diferente. Em vez de simplesmente repetir os dados para cada bloco posicionado igual de um grupo, a quantidade somada ao valor médio para cada um desses blocos poderá ser ligeiramente modificada de um quadro para outro no grupo, mesmo quando a complexidade dos blocos é a mesma. No receptor, as múltiplas instâncias do mesmo bit são extraídas e combinadas para formar um único bit recebido.
