    • onDemand profile: each media presentation is a single segment (GPAC: -single-segment)
    • ISO/IEC 23009-1:2012(E)
      • p.10: "For example, in the very simplest cases each Segment or Subsegment begins with a random access point and the boundaries of Segments or Subsegments are aligned across the Representations of an Adaptation Set. In this case, switching Representation involves playing to the end of a (Sub)Segment of one Representation and then
        playing from the beginning of the next (Sub)Segment of the new Representation."
      • p.11: "For live services, however, Segments become available with time as the content is produced. The Media Presentation Description may be updated regularly to reflect changes in the presentation over time, for example Segment URLs for new segments may be added to the MPD and those
        for old, no longer available Segments may be removed. However, if Segment URLs are described using a template, this updating may not be necessary except for some redundancy/failover cases."
      • 8.4 ISO Base media file format live profile: "Note that despite the profile is optimized for live services, the MPD@Type attribute may be set to 'static' to distribute non-live content, for example in case a live Media Presentation is terminated, but kept available as On-Demand service."
