Go live in AMD with MSL origin

You need to associate the MSL origin hostname with an Adaptive Media Delivery (AMD) property configuration in order to deliver the content.

Follow these steps to set up a new AMD property to associate with your MSL configuration.

Go to ☰ > CDN > Properties, and then click New Property.
Use the top-right menu in the header to select the appropriate Control Center account (one with access to the applicable product).
In the Property Name field, enter a desired name for the AMD property. This serves two purposes:
- The filename for the property, and
- How it is displayed for access throughout the Property Manager UIs in Control Center.
Set the Origin Server behavior options:

Option Description
Origin Type Select Media Service Live.
MSL Origin Input the Primary Hostname value.

Option	Description
Origin Type	Select `Media Service Live`.
MSL Origin	Input the `Primary Hostname` value.

Set the Segmented Media Delivery Mode behavior options.

Option	Description

Enable ULL Streaming	You can enable low latency Streaming with your Media Services Live (MSL) 4.x streams. Low latency streaming helps to reduce latency and decrease overall transfer time of DASH streams delivered via AMD. For low latency with HLS, you need to use a third-party origin. This is not supported with HDS or Smooth.

Live Type	Select either `Linear` or `Event`, based on your need.
Segment Access Time Mode	If you know the segment access time, and wish to set a specific value, leave this at `Configurable` and use the Segment Access Time options to specify a numerical duration, along with the applicable time increment of days, hours, minutes, and seconds in the drop-down menu. Otherwise, set this value to `Unknown`. Event start and end times are in GMT.
