Asset identifier event for sub parts of the period

RufaelDev commented 3 years ago

Current asset identifier is on the period level, for some burned in ads or changes within the period this is not sufficient, an event scheme with equivalent signaling is proposed to mark the asset identification of those parts:

<!-- example burned in ad with ad-id --> 
<EventStream
  schemeIdUri="urn:smpte:ul:060E2B34.01040101.01200900.00000000"
  timescale="1">
  <Event
    presentationTime="1615563936"
    duration="30"
    id="26">
    "USTR0000003H"
  </Event>
 </EventStream>

In the absence of other identification schemes, a DASH-IF defined scheme may be signalled by setting: @schemeIdUri to "http://dashif.org/guidelines/v5/asset-id" @value to a MovieLabs ContentID URN ([58], 2.2.1)

Sounds like a way of solving this issue especially for Barker channels , and clients that do not handle Multi period that well

Makes sense - should be implemented somewhere. A proposal would be nice @RufaelDev

We should also permit to change Assets whenever there is a virtual Period event - this should be added to the Amd.2 of MPEG-DASH @haudiobe.
