Abstract

desabilitação de camadas desnecessárias em sequências de bits de vídeo de múltiplas camadas. um método de decodificação é fornecido. o método inclui receber, pelo decodificador de vídeo, uma sequência de bits de vídeo incluindo um conjunto de parâmetros de vídeo (vps) e uma pluralidade de camadas, onde nenhuma camada é uma camada de saída de pelo menos um ols, nem uma camada de referência direta de qualquer outra camada, e decodificar, por meio do decodificador de vídeo, uma imagem de uma dentre a pluralidade de camadas. um método de codificação também é fornecido. o método inclui gerar, pelo codificador de vídeo, uma pluralidade de camadas e um vps especificando um ou mais conjuntos de camadas de saída (olss), onde nenhuma camada é uma camada de saída do pelo menos um ols, nem uma camada de referência direta de qualquer outra camada, codificar, por meio do codificador de vídeo, a pluralidade de camadas e o vps em uma sequência de bits de vídeo, e armazenar, por meio do codificador de vídeo, a sequência de bits de vídeo para comunicação na direção de um decodificador de vídeo.
