Abstract

um dispositivo de processamento de vídeo é configurado para obter, a partir de uma sequência de bits, um ou mais elementos indicando um ou mais esquemas de partição para um conjunto de camadas de saída. para cada esquema de partição respectivo de um ou mais esquemas de partição, o esquema de partição respectivo especifica uma divisão do conjunto de camadas de saída em uma ou mais partições. cada camada no conjunto de camadas de saída pertence a exatamente uma partição no esquema de partição respectivo. adicionalmente, o dispositivo de processamento de vídeo obtém, a partir de uma mensagem de informação de aperfeiçoamento suplementar (sei) ou informação de capacidade de utilização de vídeo (vui) em um conjunto de parâmetros de vídeo (vps), parâmetros de decodificador de referência hipotéticos (hrd) para cada um dentre o um ou mais esquemas de partição. para cada partição respectiva do esquema de partição respectivo, o dispositivo de processamento de vídeo testa, com base nos parâmetros hrd para o esquema de partição respectivo, a partição respectiva por conformidade a um padrão de codificação de vídeo.
