Abstract

APARELHO DE CODIFICAÇÃO DE IMAGEM E MÉTODO COM BASE EM SUBIMAGEM. De acordo com as modalidades do presente documento, se a informação relacionada ao limite virtual (por exemplo, informação relacionada à localização do limite virtual) é sinalizada ou não em um conjunto de parâmetros de sequência pode ser determinado com base na presença ou não da informação da subimagem. Por exemplo, quando a informação da subimagem está presente para uma sequência correspondente, a informação relacionada ao limite virtual (por exemplo, a informação relacionada à localização do limite virtual) pode ser sinalizada no conjunto de parâmetros de sequência.
