Manifest conditioned examples

This section provides manifest samples for the different protocols, generated by a packager, under the control of Prisma.

DASH Manifest sample

Upon SCTE-35 detection, a packager generally starts a new period. In the below example, we just show the beginning of the manifest for sake of clarity.

Conditioning information sent by Prisma is highlighted below.

    <Period id="146723272290" start="PT1513260090.182S">
        <EventStream schemeIdUri="urn:mime:text" timescale="90000">
            <Event presentationTime="146723272290" duration="2700000" id="35e946ae-684f-4045-b009-b681550e8521">

        </EventStream>
        <AdaptationSet mimeType="video/mp4" segmentAlignment="true" startWithSAP="1" maxWidth="640" maxHeight=
        "480" maxFrameRate="30000/1001" par="4:3">
            <InbandEventStream schemeIdUri="urn:mpeg:dash:event:2012" value="1"/>
            <SegmentTemplate timescale="90000" initialization="$RepresentationID$-Header-1513259339742.m4s" 
            media="$RepresentationID$-0-T-$Time$.m4s" presentationTimeOffset="146723273934">
                <SegmentTimeline>
		… manifest continues…

In this example, the content of the placement opportunity (SCTE-35) is encoded in XML/base64 URL. When decoding the orange part highlighted above, the following XML structure is given:

<?xml version="1.0" encoding="utf-8" ?>
<Signal>
    <SpliceInfoSection scte35Point="146723272290">
        <SpliceInsert spliceEventId="1234"  outOfNetworkIndicator="1"
          uniqueProgramId="0" availNum="0"><BreakDuration duration= "PT30S"/>
        </SpliceInsert>
    </SpliceInfoSection>
</Signal>

This information can then be used by downstream manifest manipulator, or directly by the player to understand a break of 30 seconds signaled via splice insert command is on-going at designated splice point time (scte35Point).

An example of conditioned HSS manifest is given below, with the conditioning info sent by Prisma highlighted in orange.

Similar to DASH, conditioning info is formatted in XML, and encoded in base64URL.
