摘要： A processor system and computer-implemented method are provided for generating a composite video stream which may include a non-volumetric video and a volumetric video, at least part of which is to be displayed in front of the non-volumetric video. The volumetric video may be included in the composite video stream in the form of a non-volumetric representation of the volumetric video, for example inserted into a spatial subregion of the non-volumetric video which may be occluded by the volumetric video during display. The encoding, transmission and decoding may thus not have to be modified to support volumetric video. Signaling data may be provided which may be indicative of the composite video stream containing the non-volumetric representation of the volumetric video. A processor system and computer-implemented method may be provided for rendering the composite video stream using the signaling data.
