Abstract
MÉTODO DE PROCESSAMENTO DE VÍDEO, APARELHO PARA PROCESSAR DADOS DE VÍDEO, E, MEIOS DE ARMAZENAMENTO E DE GRAVAÇÃO LEGÍVEIS POR COMPUTADOR NÃO TRANSITÓRIOS. Um método de processamento de vídeo inclui realizar uma conversão entre um vídeo e um fluxo contínuo de bits do vídeo, em que o fluxo contínuo de bits compreende um ou mais conjuntos de camada de saída (OLSs), cada qual compreendendo uma ou mais camadas de vídeo, em que o fluxo contínuo de bits se conforma com uma regra de formato. A regra de formato especifica se ou como um primeiro elemento de sintaxe que indica se uma primeira estrutura de sintaxe descritiva de parâmetros de um decodificador de referência hipotético (HRD) usado para a conversão é incluída em um conjunto de parâmetro de vídeo (VPS) do fluxo contínuo de bits.
