Abstract

um aparelho, um método e um programa de computador para codificação e decodificação de vídeo. é revelado um método, um aparelho e um produto de programa de computador para codificação e decodificação de vídeo. de acordo com uma modalidade, o método para codificação compreende concluir que uma sequência de vídeo codificada começa em posição particular em um fluxo de bits, em que a sequência de vídeo codificada é uma sequência de imagens codificadas em ordem de decodificação que é decodificável independentemente e é seguida por outra sequência de vídeo codificada ou o final do fluxo de bits, e em que o fluxo de bits compreende unidades de acesso, e uma unidade de acesso compreende dados de vídeo codificado para uma única ocorrência no tempo e outros dados associados, e uma unidade de acesso compreende uma ou mais unidades de camada de abstração de rede (nal); e indicar, em um delimitador de unidade de acesso para tratar, a(s) unidade(s) de nal associada(s) ao delimitador de unidade de acesso como um início de uma sequência de vídeo codificada.
