Segmented Media Delivery Mode and AMD

Use this to set the delivery mode for your content to tune the configuration for that specific mode: On Demand (Default) vs. Live.

Among other things, this adjusts the Time-to-Live (TTL) of the manifests if no specific caching rules are defined. For example, "Live" assigns a very short TTL to the stream manifest file so that updates to the manifest are retrieved in a timely manner.

Important: The best practices and use case-based provisioning that Akamai automatically applies to optimize delivery are not supported if you've set the Mode to "Live." They are only added for "On Demand" Mode content.

Advanced Options for "Live" Mode

If you've selected "Live" as the Mode, the Show Advanced Option slider can be set to "Yes" to reveal additional options. These are used when configuring Media Services Live for use with AMD and are discussed in the MSL 4.x and AMD - Getting Started Guide.

Enable ULL Streaming for "Live" Mode

If you've selected "Live" as the Mode, you can also incorporate ultra low latency (ULL) streaming with your Media Services Live (MSL) 4.x streams. ULL streaming takes advantage of Akamai's chunked transfer encoding (CTE) feature as well as various Property Manager behaviors to reduce latency and decrease overall transfer time of live streams. ULL streaming requires specific configuration in both MSL 4.x and your AMD property. This is fully covered in the MSL 4.x - User Guide.

Important: The Advanced Options and Enable ULL Streaming settings only apply to the use of MSL 4.x with AMD. They can't be used with your own custom live media configuration.

Are you incorporating Use Case-based Edge Mapping or Mixed Mode Configuration?

If you're adding either of these services to your AMD property configuration, the following apply:

  • I'm only using Use Case-based Edge Mapping. During creation of your property hostname to edge hostname association, if you've set the "Use Case" setting to either Live or On Demand, you need to match that setting here. Complete setup is discussed in How to add Use Case-based Edge Mapping.
  • I'm using Mixed Mode Configuration for AMD. This lets you include use case-based behaviors like Segmented Media Delivery Mode in rules outside the Default Rule, in order to optimize delivery for unique requests using specific match criteria. If you're including this behavior in multiple rules, ensure that it's set to match the applicable delivery mode for each rule. See How to use Mixed Mode with AMD for more details.
