Overview

Create a new Harmonic-backed live stream with optional secondary cluster redundancy.

:::tip At a Glance
Who is this for?

Operators and content teams creating Harmonic live channels.

When do I use this?

When you need Harmonic ingest and, if needed, secondary-cluster failover.

What will happen?

A Harmonic live stream is created and opened in its live details view after successful submission.
:::

Prerequisites

  • You can open Live Create in the Content module.
  • You know your target Harmonic region and ingest protocol.
  • If you plan to use existing inputs or sources, those records are available to select.

Steps

Step 1: Open Live Create and choose Harmonic

Open Live Create, stay on the Viewlift live stream service tab, and choose Harmonic as provider.

Step 2: Set Partner, Region, and Protocol

In Partner, Region & Protocol:

  1. Confirm Provider is Harmonic.
  2. Select Region.
  3. Select Protocol:
    • RTMP PUSH
    • SRT LISTENER
    • SRT CALLER

Step 3: Configure Ingest Setup branch

In Ingest Setup:

  1. If needed, enable Use for Linear Channel.
  2. Set Ingestion Identifier when your branch requires it.
  3. Optionally enable Backup Endpoint.
  4. Choose one primary strategy:
    • Use Existing Input (Primary)
    • Use Existing Source (Primary)
    • Manual SRT Caller fields

Primary strategies are mutually exclusive in the UI. Pick one and complete it fully.

Branch Typical inputs shown
Existing input path Primary Main Live Input, optional Primary Backup Live Input
Existing source path Primary Main Source, optional Primary Backup Source
Manual SRT Caller path Primary IP, Primary Port, optional stream and decryption values

Step 4: Configure Redundancy & Failover (optional)

If you need secondary-cluster resiliency:

  1. Enable Backup / Secondary Configuration.
  2. Select Backup Cluster Region.
  3. Choose one secondary strategy:
    • Use Existing Input (Secondary Cluster)
    • Use Existing Source (Secondary Cluster)
  4. If protocol and branch require it, fill manual backup SRT fields.

When secondary is enabled, complete all required secondary selections before creating.

Step 5: Configure Playback, Ads, and Security

In Playback, Ads & Security:

  1. Enable SSAI if needed.
  2. Choose Ad Provider.
  3. If Ad Provider is Media Tailor, select Primary MediaTailor Input.
  4. If secondary service is enabled, select Secondary MediaTailor Input.
  5. Enable DRM if needed.
  6. If DRM is enabled and service type supports it, enable key rotation if required.

Step 6: Configure Recording, Macros, and Schedule

Complete operational settings:

  1. Recording & Catch-Up: enable Live to VOD and/or DVR (as available for your service mode).
  2. If DVR is enabled, enter Start-Over Time.
  3. Configure Macros if needed.
  4. If service type is LIVE_EVENT, complete Schedule (start time required).

Step 7: Create the live stream

Click Create Live Stream.

If required values are missing in any selected branch, submission is blocked and field-level messages are shown.

Expected Behavior

  • Harmonic branch options appear after provider, region, and protocol are selected.
  • Existing input and existing source toggles are mutually exclusive for both primary and secondary paths.
  • Secondary fields appear only after enabling secondary configuration and selecting backup region.
  • LIVE_EVENT shows schedule fields; LIVE mode does not show schedule.
  • Some toggles may be disabled depending on your account permissions.
  • On success, the app opens the newly created live stream details page.

  • Read top to bottom.
  • Diamond nodes are decisions that branch the UI.
  • Rectangles are screens or input groups you complete.
  • Follow one branch at a time based on your selections.

Edge Cases / Notes

  • Secondary setup is strict: incomplete backup selections block create.
  • For SRT Caller paths, endpoint details are required before submission.
  • If Media Tailor is chosen, required MediaTailor selection must be complete for active clusters.
  • Schedule end time is optional for LIVE_EVENT, but start time is required.

If Something Goes Wrong

  • Secondary branch validation fails: one or more secondary selections are incomplete.
    Resolution: complete backup region and all required secondary fields for your chosen path.
  • SRT Caller validation fails: endpoint or decryption inputs are incomplete.
    Resolution: provide required primary values and valid decryption input if used.
  • Schedule validation fails: LIVE_EVENT start date/time is missing or invalid.
    Resolution: provide a valid start time (and adjust end time if used).
