Abstract

informações de janela de conformidade na criptografia de múltiplas camadas trata-se de um sistema e método para criptografar uma figuração em um fluxo de bits de múltiplas camadas. em um aspecto, o método inclui codificar pelo menos uma camada do fluxo de bits de múltiplas camadas de acordo com um primeiro esquema de criptografia. o fluxo de bits de múltiplas camadas pode compreender uma camada-base. o método inclui adicionalmente codificar um sinalizador de janela de conformidade e pelo menos um deslocamento de posição para a figuração em um conjunto de parâmetros de vídeo (vps) da camada-base. o sinalizador de janela de conformidade pode indicar que o vps compreende o pelo menos um deslocamento de posição.
