Amendment 7 to ITU-T H.222.0 (2014) | ISO/IEC 13818-1:2015 enables signaling and notation of a stream with virtual segmentation carried in MPEG-2 transport stream. The signaling of the stream that is comprised of virtual segmentation is indicated within the PMT using virtual segmentation descriptor. The virtual segment itself is made up of a boundary point af_descriptor to indicate virtual segment locations within a stream, a labeling af_descriptor which notes the different types of label associated with the virtual segment, and an associated TEMI timeline af_descriptor.
