Abstract

trata-se de técnicas e sistemas para criptar dados de vídeo. por exemplo, um método de criptação de 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 ou mais conjuntos de parâmetros de sequência e um conjunto de parâmetros de vídeo. o método inclui adicionalmente gerar, de acordo com uma restrição, um ou mais parâmetros de formato de representação para um conjunto de parâmetros de sequência atribuído a uma camada-base do fluxo de bits de vídeo criptado. a restrição limita os valores do um ou mais parâmetros de formato de representação no conjunto de parâmetros de sequência como sendo menores ou iguais aos valores de parâmetros de formato de representação correspondentes que são atribuídos à camada-base no conjunto de parâmetros de vídeo.
