Abstract (en)
[origin: WO2023025980A1] The embodiments relate to a method and technical equipment for implementing the method. The method comprises obtaining bitstreams of at least two 3D volumetric representations, wherein a first 3D volumetric representation is encoded according to a first format and a second 3D volumetric representation is encoded according to a second format (500); analyzing content and semantics of syntax elements of said at least two 3D volumetric representations (502); determining one or more signaling elements, based on the analysis, to indicate differences in the semantics of the syntax elements between the first format and the second format (504); and encoding the bitstreams of said at least two 3D volumetric representations into a multi-format volumetric representation (506).
