DASH Manifest Segment Numbering

MediaTailor supports media segments in <SegmentTemplate> that are defined using <SegmentTimeline> and the media attribute. You can specify the media segment list in the media attribute using either the $Number$ identifier or the $Time$ identifier.

The following example shows a SegmentTemplate with a media attribute setting that uses the $Number$ identifier:

<SegmentTemplate initialization="index_subtitles_4_0_init.mp4?m=1532451703" media="index_subtitles_4_0_$Number$.mp4?m=1532451703" presentationTimeOffset="1062336677920" startNumber="2349899" timescale="90000"> <SegmentTimeline> <S d="540540" r="2" t="1062338840080"/> <S d="69069" t="1062340461700"/> </SegmentTimeline> </SegmentTemplate>

The following example shows a SegmentTemplate with a media attribute setting that uses the $Time$ identifier:

<SegmentTemplate initialization="asset_720p_8000K_9_init.mp4" media="asset_720p_8000K_9_$Time$.mp4" startNumber="1" timescale="90000"> <SegmentTimeline> <S d="180000" r="2" t="0"/> <S d="147000" t="540000"/> </SegmentTimeline> </SegmentTemplate>
