Abstract

um dispositivo para codificação de dados de vídeo de multicamada é configurado para determinar um valor de contagem de ordem de imagem (poc) para uma imagem atual; determinar um valor de poc para uma imagem de referência; determinar um valor identificação de camada (id) para a imagem atual; determinar um valor de id de camada para a imagem de referência; receber condicionalmente um sinalizador indicando se a predição ponderada está habilitada ou desabilitada através do recebimento do sinalizador em resposta a pelo menos uma das duas condições sendo verdadeiras e não recebendo o sinalizador em resposta às duas condições sendo falsas, sendo que nas duas condições (1) o valor de poc da imagem atual não é igual ao valor de poc da imagem de referência, e (2) o valor de id de camada para a imagem atual não é igual ao valor de id de camada para a imagem de referência.
