Abstract
armazenamento em buffer de vídeo de baixo retardo em codificação de vídeo como um exemplo, um método de codificação de dados de vídeo inclui o armazenamento de uma ou mais unidades de decodificação de dados de vídeo em um buffer de imagem codificada (cpb). o método inclui adicionalmente a obtenção de um tempo de remoção de armazenamento respectivo para uma ou mais unidades de decodificação. o método inclui adicionalmente a remoção das unidades de decodificação do cpb de acordo com o tempo de remoção de armazenamento obtido para cada uma das unidades de decodificação. o método inclui adicionalmente a determinação de se o cpb opera no nível de unidade de acesso ou nível de sub-imagem. o método inclui adicionalmente a codificação de dados de vídeo correspondendo às unidades de decodificação removidas. se o cpb operar no nível de unidade de acesso, a codificação de dados de vídeo compreende a codificação de unidades de acesso compreendidas nas unidades de decodificação. se o cpb operar no nível de sub-imagem, a codificação de dados de vídeo compreende a codificação de subconjuntos de unidades de acesso compreendidas nas unidades de decodificação.
