Abstract
1/1 resumo conjuntos de parâmetros de codificação para várias dimensões em codificação de vídeo em um exemplo, um dispositivo para codificar 5 dados de vídeo inclui um codificador de vídeo configurado para codificar, para um fluxo de bits, informações representativas de quais de uma pluralidade de dimensões de codificação de vídeo são habilitadas para o fluxo de bits, e valores de código para cada das dimensões de codificação 10 de vídeo habilitadas, sem codificar valores para as dimensões de codificação de vídeo que não são habilitadas, em um cabeçalho de unidade de camada de abstração de rede (nal) de uma unidade nal compreendendo dados de vídeo codificados de acordo com os valores para cada das 15 dimensões de codificação de vídeo habilitadas. desse modo, cabeçalhos de unidade nal podem ter comprimentos variáveis, enquanto ainda fornecem informações para dimensões redimensionáveis às quais as unidades nal correspondem.
