Quando o HDCP era uma tecnologia sem falhas

HDCP é um proteção de conteúdo digital em banda larga. Ou seja, ele é um sistema de proteção anti cópia desenvolvido pela Intel para proibir que todo conteúdo protegido por direitos autorais possa ser distribuido e armazenado gratuitamente.

Pelo que dizem, o HDCP é uma tecnologia complexa e que faz mais que apenas impedir cópias de discos. Ele é uma solução completa para impedir que cópias de video digital de alta resolução sem copiadas. Tudo que usa cabos HDMI, também usa essa proteção HDCP.

Ele funciona assim: todo e qualquer aparelho de blue-ray sai de fábrica com m código, toda e qualquer tv HD também tem esse código. Quando esses aparelhos são conectados, um terceiro código é criado e esse código é usado para criptografar o sinal de vídeo final, tornando impossível que, esse sinal, seja tocado por qualquer outro aparelho. É por isso que existe um delay na tv digital brasileira. É assim que se impede a presença de um gravador entre a tv e um player de blue-ray.


Até hoje, esse sistema não tinha falhas mas um post no Pirate Bay vazou o código fonte para a criação desses códigos. E logo abaixo, você pode ter acesso a esse código.
