Abstract

De acuerdo con modalidades del presente documento, si información relacionada con límites virtuales (por ejemplo, información relacionada con la ubicación de límites virtuales) es señalizada o no en un conjunto de parámetros de secuencia puede determinarse sobre la base de si está presente o no información de subimágenes. Por ejemplo, cuando la información de subimágenes está presente para una secuencia correspondiente, la información relacionada con límites virtuales (por ejemplo, la información relacionada con la ubicación de límites virtuales) puede señalizarse en el conjunto de parámetros de secuencia.
