Abstract
sistema e método para evitar a manipulação de dados de vídeo transmitidos. o objetivo da invenção é fornecer uma solução para assegurar que o conteúdo enviado pelo ird é o conteúdo efetivamente exibido na tela. é então proposto um sistema para evitar manipulação de dados de vídeo transmitidos compreendendo um decodificador receptor integrado (ird) que recebe dados de áudio/vídeo, um dispositivo de display (tv), o ird compreendendo meio para transmitir um fluxo de áudio/vídeo em comformidade com hdmi em direção ao dispositivo de display, caracterizado pelo fato de que o sistema compreende ainda meio para adicionar uma camada de criptografia adicional ao fluxo de hdmi/hdcp antes de atingir o dispositivo de display e meio para remover essa camada de criptografia adicionada de modo a recuperar o fluxo hdmi/hdcp, antes de processar o fluxo hdmi/hdcp pelo dispositivo de display.
