摘要： A method of decoding includes decoding a coded stream obtained by coding first and second groups for each access unit including a picture of the first group and a corresponding picture of the second group, wherein the first and second groups are captured at different view points. The method includes determining whether the picture of the first group is synchronized with the picture of the second group, within the access unit, and decoding the picture of the first group using a generated predictive picture of the first group. The method also includes decoding the picture of the second group, using one of (i) a predictive picture generated from the second group and (ii) the predictive picture generated from the first group.
