Abstract[English]
Various embodiments provide example apparatus, method, and computer program product. An example apparatus includes: receiving or generating a first encoded bitstream comprising independently encoded subpictures; receiving or generating a second encoded bitstream comprising independently encoded subpictures; wherein resolution of subpictures in the second encoded bitstream is same or substantially same as resolution of corresponding subpictures in the first encoded bitstream; generating an encapsulated file with a first track and second track, the first track comprises the first encoded bitstream comprising the independently encoded subpicture, the second track comprises the second encoded bitstream comprising the independently encoded subpictures; and wherein generating the encapsulated file comprises including following information in the encapsulated file: a picture-in-picture relationship between the first track and second track; and data units independently encoded subpictures in the first encoded bitstream that are to be replaced by data units of the independently encoded subpictures of the second encoded bitstream.[French]
Divers modes de réalisation concernent un appareil, un procédé, et un produit-programme d'ordinateur donnés à titre d'exemple. Un appareil donné à titre d'exemple consiste à : recevoir ou générer un premier flux binaire codé comprenant des sous-images codées indépendamment; recevoir ou générer un second flux binaire codé comprenant des sous-images codées indépendamment; la résolution de sous-images dans le second flux binaire codé étant identique ou sensiblement identique à la résolution de sous-images correspondantes dans le premier flux binaire codé; générer un fichier encapsulé avec une première piste et une seconde piste, la première piste comprenant le premier flux binaire codé comprenant la sous-image codée indépendamment, la seconde piste comprenant le second flux binaire codé comprenant les sous-images codées indépendamment; et la génération du fichier encapsulé comprenant l'insertion des informations suivantes dans le fichier encapsulé : une relation d'incrustation d'image entre la première piste et la seconde piste; et des unités de données codées indépendamment des sous-images dans le premier flux binaire codé qui doivent être remplacées par des unités de données des sous-images codées indépendamment du second flux binaire codé.
