Abstract

"MéTODO E APARELHO PARA SERVIçOS MELHORADOS DE áUDIO/VìDEO COM MARCAS D'áGUA E DADOS ASSOCIADOS". Método e aparelho para cópia controlada de um sinal de áudio ou vídeo transmitido por uma televisão a cabo ou sistema de transmissão direta via satélite ou pela Internet. O material de áudio ou vídeo está protegido por direitos autorais (ou outros direitos) contra cópia (gravação) não desejada pela combinação de uma marca d'água embutida no sinal de áudio ou de vídeo na extremidade junto com dados adicionais de proteção contra cópia inseridos no sinal de áudio ou vídeo, um passe ou uma segunda marca d'água. A linha de vídeo (21) no intervalo de apagamento vertical para (TV NTSC) é usado para reter o passe (contador criptográfico). Uma marca d'água é embutida na parte ativa do vídeo do sinal de áudio ou de vídeo. Somente se o consumidor estiver desejando pagar uma taxa serão o sinal de vídeo com ambos a marca d'água e o passe transmitidos para seu dispositivo de gravação, que então compara a marca d'água com a função matemática do passe e somente se eles coincidirem, a gravação será permitida. Opcionalmente, este controle de consumidor pode operar numa segunda marca d'água no áudio ou vídeo. O dispositivo de reprodução correspondente produz um sinal de áudio ou vídeo que não possui o passe e, portanto, nenhuma outra cópia é permitida. Isto possibilita que uma única cópia seja feita ao ser paga.
