Abstract

trata-se de conjuntos de procedimentos e sistemas para criptar e decodificar dados de vídeo. por exemplo, um método para criptar dados de vídeo inclui gerar um fluxo de bits de vídeo criptado que compreende múltiplas camadas. o fluxo de bits de vídeo criptado inclui um conjunto de parâmetros de vídeo que define parâmetros do fluxo de bits de vídeo criptado. o conjunto de parâmetros de vídeo inclui informações de usabilidade de vídeo. o método inclui adicionalmente determinar se as informações de temporização são sinalizadas nas informações de usabilidade de vídeo do conjunto de parâmetros de vídeo. o método inclui adicionalmente determinar se deve-se sinalizar parâmetros de decodificador de referência hipotética nas informações de usabilidade de vídeo do conjunto de parâmetros de vídeo com base em se as informações de temporização são sinalizadas nas informações de usabilidade de vídeo.
