ZEN Master 17 Feb 2026 Release
The following updates were included in the ZEN Master release for Feb 17th, 2026.
Features
The following new features were implemented in this release:
SCTE-35 modification
Related docs:
- Note: This feature is a module addition, please speak to your account rep for more information.
- ZEN Master introduces the SCTE modification suite allowing users to insert, remove, or manipulate existing SCTE35 markers.
- When enabled, SCTE-35 Modification Profiles appear under the ‘Transformations’ menu.
Begin by naming and tagging the profile, and defining the default action for SCTE-35 messages that do not match your rules.
Once a new Rules is named and a default action set, specific matching triggers can be set up along with associated action:
Each Rule is configured to Keep, Remove, or Modify a SCTE-35 message based on a matching trigger and in the case of a modification the subsequent replacement message:
All SCTE-35 messages on a target with the profile are evaluated against rules within the profile. If a SCTE-35 payload parameter matches the User defined triggering parameter value, then that SCTE-35 message will be kept, removed, or modified as per any outlined modification parameters. If there are multiple triggers, the SCTE-35 message should match ALL criteria in order to action the rule.
SCTE-35 Modification Rule Simulator.
Once created, SCTE-35 modification rules can be tested directly within the ZEN Master interface.
- After choosing the Simulator tab, an example message can be entered in the input field and Users can ‘Run’ the input against the Rule.
- The rules and associated priorities of actions will be matched in turn and applied against the example input.
- The decoded message and modification result is made available in JSON or XML format.
Rule Application.
- Once Created, SCTE-35 Modification Profiles can be applied to Targets in the advanced SCTE-35 Manipulation section of the New/Edit Target Dialog:
AWS SSM integration
Related docs:
- ZEN Master now provides the facility to run AWS SSM commands directly within the ZEN Master User Interface.
- Whilst multifunctional, this feature is primarily provided in support of Infosec teams with system update and patching requirements.
- The AWS SSM Tool can be launched from the selected Broadcaster details page:
When opened, the “Run SSM Command” dialog opens to display:
- Current Broadcaster details (un-editable).
- A dropdown list of SSM Commands (e.g. ‘yum update’) available to ZEN Master.
- The Broadcaster Active Objects table.
- The Close / Run SSM Command action buttons.
When running a command, ZEN Master:
- Updates the active object status with the initial and current status of all objects.
- Monitors the SSM status and displays the tail end of the command output in SSM.
- Upon successful completion, notifies the User.
- Should the script fail, the User can use the error status and output notes to facilitate further investigation.
Instance Refresh
Related Docs:
AWS Instance Refresh
- ZEN Master provides the facility to refresh an AWS Instance.
- This feature allows Users to ‘swap’ out the existing instance for a fresh instance, useful for OS patching, instance re-sizing, OS Updates etc.
- The new instance will re-connect to ZEN Master “in-place” of the existing instance.
- The Instance Refresh Tool can be launched from the selected Broadcaster details page:
- When opened, the “Refresh Instance” dialog opens to display:
- Current Broadcaster details (un-editable).
- The Broadcaster Active Objects table.
- The Close / Refresh Instance action buttons.
When Refreshing an Instance, ZEN Master will:
- Update the active object status with the initial and current status of all objects.
- Monitor the Broadcaster status.
- Notify the User on completion success.
Note: to make changes to the instance details, customer AMI Used, instance type etc., edit the Cluster settings before running the Refresh Instance Tool.
TAMS Support
Related Docs:
TAMS Support
ZEN Master adds coverage of the Zixi Broadcaster integration to Time Addressable Media Store (TAMS) format.
- Requires Zixi Broadcaster v19.
Channel Configuration:
- the ‘TAMS Enabled’ in the Transcoded or Adaptive Channel in the New/Edit Channel dialog.
- This will allow for the configuration of the addition video and audio UUID’s required by the TAMS format.
- For Transcoded Channels, this will include the optional source pass through.
- All other renditions will also provide a UUID entry field.
- The presence of a value in the UUID field will result in the generation of an associated TAMS variant.
Target Configuration:
- A TAMS Target Type can now be created via the New “HTTP” Target menu.
- Here the User is presented with:
- The option to set a TAMS target sub-type.
- The URL of the intended TAMS Server endpoint.
- Credentials, Auth Token URL, and deletion Scope options.

- Backwards compatibility for NULL Packet Search Window field in SCTE-35 manipulation.
- Splice Inserts SCTE-35 messages are now tracked separately in the graph based on into/out of network flag. o Updated decoded SCTE-35 display to use ‘threefive’ compatible format and added standard XML option.
- Date/Time selectors now use User-selected Date/Time format.
