Abstract

"SINAL DE VìDEO ANALóGICO, APARELHO PARA E PROCESSO DE EMBUTIR UM SINAL DE PASSE EM UMA OU MAIS LINHAS DE UM SINAL DE VìDEO ANALóGICO, E, SUPORTE DE GRAVAçãO". Recentes esquemas de proteção contra cópia para proteção de cópia de vídeo digital confiam sobre uma marca d'água pixel juntamente com a presença de um sinal passe para implementar o estado 'copiar uma vez' do conteúdo. Este sinal passe é projetado para habilitar o proprietário de um disco/fita a tirar uma cópia do conteúdo digital. Apresenta-se um processo de passar este sinal passe com o sinal de vídeo após o conteúdo ter sido convertido para o domínio analógico. Esta forma do sinal passe é designada de passe analógico. O sinal analógico pode ser gravado sobre um dispositivo legado que não satisfaz o esquema de proteção contra cópia (p.ex., VCRs usuais). O sinal de passe analógico é projetado de tal maneira que seja automaticamente removido nestes dispositivos legados. A tiragem de cópias da próxima geração por dispositivos complacentes é tornada impossível. Três maneiras possíveis de embutir o sinal passe no sinal de vídeo analógico são propostas.
