Abstract
é revelado um método para criptografar um bloco de dados de vídeo no modo de previsão de bloco de um esquema de criptografia de vídeo de taxa de bit constante para transmissão através de enlaces de exibição. em um aspecto, o método inclui determinar uma ou mais primeiras regiões-candidatas a serem usadas para prever uma região atual dentro do bloco de dados de vídeo com o uso de um primeiro esquema de particionamento, determinar uma ou mais segundas regiões-candidatas a serem usadas para prever a região atual com o uso de um segundo esquema de particionamento, determinar que um primeiro custo associado à criptografia da região atual com o uso do primeiro esquema de particionamento é maior do que um segundo custo associado à criptografia da região atual com o uso do segundo esquema de particionamento e criptografar a região atual com o uso do segundo esquema de particionamento.
