(EN) SAMPLE GROUPING SIGNALING IN FILE FORMATS
(FR) SIGNALISATION DE REGROUPEMENT D'ÉCHANTILLONS DANS DES FORMATS DE FICHIERS
Abstract
(EN)
A device generates, in a container box of a file for storage of video contents, a SampleGroupDescription box that provides a sample group description for a sample grouping. The SampleGroupDescription box includes a grouping type syntax element having a particular value. Additionally, the SampleGroupDescription box includes one or more sample group entries. The device generates, in the same container box, a plurality of SampleToGroup boxes. Each respective SampleToGroup box of the plurality of SampleToGroup boxes includes a respective grouping type syntax element having the particular value, includes a respective sample count syntax element indicating a number of samples in a respective sample grouping, and includes a respective group description index syntax element indicating an index of an entry in the SampleGroupDescription box which describes samples of the respective sample grouping. Each sample of the respective sample grouping comprises a respective picture of the video contents.

L'invention fait intervenir un dispositif qui génère, dans une case conteneur d'un fichier servant au stockage de contenus vidéo, une case SampleGroupDescription qui donne une description de groupe d'échantillons pour un regroupement d'échantillons. La case SampleGroupDescription comprend un élément syntaxique de type de regroupement présentant une valeur particulière. De plus, la case SampleGroupDescription comprend une ou plusieurs entrées de groupe d'échantillons. Le dispositif génère, dans la même case conteneur, une pluralité de cases SampleToGroup. Chaque case SampleToGroup respective de la pluralité de cases SampleToGroup comprend un élément syntaxique respectif de type de regroupement présentant la valeur particulière, comprend un élément syntaxique respectif de comptage d'échantillons indiquant un nombre d'échantillons dans un regroupement d'échantillons respectif, et comprend un élément syntaxique respectif d'index de description de groupe indiquant un index d'une entrée dans la case SampleGroupDescription qui décrit des échantillons du regroupement d'échantillons considéré. Chaque échantillon du regroupement d'échantillons considéré comporte une image respective des contenus vidéo.
