1. A method, comprising: associating, utilizing a processor, a multimedia scene comprising a plurality of multimedia objects organized in at least one scene description tree with a sub-tree of the objects to be rendered and a standby sub-tree, where the sub-tree comprises objects intended to be rendered at a given instance, and where the standby sub-tree comprises objects intended not to be rendered at the given instance; identifying a transferable object of the sub-tree able to be transferred between the sub-tree and the standby sub-tree according to at least one predetermined transfer condition; transferring the transferable object of the sub-tree to the standby sub-tree, the transferable object of the sub-tree having an original unique identifier; and defining an inactive object intended to replace in the sub-tree the transferred object displaced to the standby sub-tree, the inactive object including a unique identifier that enables a return of the transferred object from the standby sub-tree to the sub-tree, wherein the unique identifier of the inactive object is obtained by application of a bijective function to the original unique identifier of the transferred object, such that uniqueness is maintained between the original unique identifier of the object transferred to the standby sub-tree and the unique identifier of the inactive object that replaced the transferred object in the sub-tree; wherein each of the multimedia objects include a first identification label having a first value if an object is to be placed in the sub-tree of the objects to be rendered, and a second value if the object is to be placed in the standby sub-tree; wherein at least one of the multimedia objects includes a second locating label having a first value if at least one ascendant of the at least one object is placed in the standby sub-tree.
