Abstract: A method of forming a video signal by a decoder device is described wherein the method comprises receiving a bitstream and decoder information, the decoder information signaling the decoder device the presence of one or more resolution components in the bitstream for forming a video signal, a resolution component representing a spatially subsampled version, preferably a polyphase subsampled version, of a first video signal having a first resolution, the one or more resolution components being part of a resolution component group, the group comprising a plurality of resolution components on the basis of which the first video signal is reconstructable; and, the decoder device parsing the bitstream and decoding the one or more resolution components into video frames on the basis of the decoder information.
