Abstract

derivação de informação de instalação de id temporal sps para fluxos de bits de multicamadas. de acordo com certos aspectos, um aparelho para codificar informação de vídeo inclui uma memória e um processador configurados para determinar se um primeiro elemento de sintaxe está presente em um fluxo de bits, o primeiro elemento de sintaxe associado a um conjunto de parâmetros de sequência (sps) e um primeiro indicador indicativo de se um identificador temporal (id) de uma imagem de referência para imagens que se referem ao sps pode ser instalado; e em resposta à determinação de que o primeiro elemento de sintaxe não está presente no fluxo de bits: obter um segundo elemento de sintaxe indicativo de um número máximo de subcamadas temporais em uma camada específica da pluralidade de camadas; e determinar se deve definir o primeiro indicador igual a um segundo indicador indicativo de se um id temporal de uma imagem de referência para quaisquer imagens pode ser instalado com base pelo menos em parte em um valor do segundo elemento de sintaxe.
