Adding RTMP Targets
ZEN Master enables you to 'Push' a channel to an RTMP server. You can configure redundant RTMP hosts to ensure consistency. To learn more about redundancy in ZEN Master see Redundancy in ZEN Master.
The following procedure describes how to add an RTMP Target in ZEN Master. In addition, an explanation of each of the configuration parameters is given in the table below.
To add a new RTMP Target:
In the main navigation, click Targets.
Click + Add. The Create New Target window is displayed.

Click on RTMP. The Create New RTMP Target window is displayed.

In the Info section, in the Name field, enter a logical name for the RTMP target.
In the Tags field, select one or more of the predefined Tags from the drop-down list. Tags are used for access control. By selecting a Tag you are relating this target to that Tag. Tags are associated with certain roles (through the Users & Roles screen), and roles, in turn, are associated with users and user groups. If you would like to create a new Tag, see Creating a Tag .
In the Events Configuration Profile field, select from the dropdown list the profile that you would like to apply to this Target. By default, the Default profile is applied.
Events Profiles consist of a series of rules that determine precisely how various types of Events are logged and what results they trigger.
The Target's location is used to represent it in the proper position in the Map display (see Maps). By default, the location is determined automatically based on the Target's IP. If you would like to manually set the location of the Target (Optional), use the following procedure:
- Click on the Edit icon next to the Location field. A search box is shown below the Location field.
- Enter identifying info for the location (e.g. street address, zip code, coordinates). Search results are displayed below the search box as you type.
- Click on the desired location. The selected location populates the Location field.
In the Configuration section, under Channel Type select the type of Channel that the Target will receive. Options are: ZEN Master Channel or AWS MediaLive Channel.
In the Configuration section, in the Channel field, select from the drop-down list the channel that will be sent to the target. (Optional field)
The target will only become functional once a channel has been assigned to it. However, you can configure the target settings and then add a channel to the target after the initial configuration.
In the Source Preference field, select one of the following options:
- Any Source – the Target will establish a connection to any available source in the Channel. Upon any disconnects with the current source, the Target will reconnect to another available source in the Channel.
- Primary Sources Only – the Target will establish and maintain connection to a source designated as Primary in the Channel. Upon loss of connection to that source, the Target will establish a connection to another available Primary source in the Channel.
- Backup Sources Only – the Target will establish and maintain connection to a source designated as Backup in the Channel. Upon loss of connection to that source, the Target will establish connection to another available Backup source in the Channel.
- Specific Source – select one of the specific sources listed. The Target will only establish a connection to the selected source and will not try to connect to any other source in the Channel.
It is not possible to select "Prefer Primary Sources" or "Prefer Backup Sources". This means you cannot have a Target failover from a Primary to a Backup source in the Channel unless "Any Source" is selected.
In the Single Output checkbox, select this option if you want there to be a single output. This option provides less redundancy but is required for servers that do not properly support concurrent connections.
If you have selected the AWS MediaLive Channel as the channel type option, in the Transcoding Profile field, select the desired transcoding profile.
In the Target field, enter the URL of the primary RTMP server.
In the Alt. Target field, enter the URL of a backup RTMP server. (Optional field)
In the Stream Name field, enter the RTMP stream name as defined in the RTMP server (Target).
In the Username field, enter the RTMP stream access credentials – User name.
In the Password field, enter the RTMP stream access credentials – Password. Click Show to display the password.
If you would like to apply a PID Mapping profile to this Target, then in the PID Mapping Profile field, select the desired profile from the dropdown list. For more information, see PID Mapping Profiles .
In the Initial State section, select the Disabled checkbox if you would like to disable this Target upon initial configuration.
Select the Muted checkbox if you would like to disable error/recovery notifications for this Target upon initial configuration.
You can Enable/Unmute the Target at any time.
Under Protections, select the Channel reassignment protection chekbox if you want to prevent the reasssignment of this Target to another Channel. This is helpful in cases where you are switching the channel on multiple targets at once and can accidetaly select a Target that should not have been switched to the new Channel.
If you use POIS, expand the SCTE-35 Manipulation (POIS) section to see additional options.

Select Enable SCTE-35 Manipulation to enable insertion and management of SCTE-35 messages (used typically to create ad breaks).
If you have created SCTE-35 Modification Profiles and want to apply it to this target, select it from the dropdown list. Note that if you select a profile, the Remove Existing SCTE-35 option will automatically be checked and non-editable - the way the modification works is that the Broadcaster will remove all SCTE-35 messages, and then re-insert them in original or modified form acccording to the rules defined in the profile.
In the NULL Packet Search Window field, specify the time window in milliseconds of NULL packets to search for in order to insert SCTE-35 messages into the stream:
- If the stream is VBR, set the value to 0 - SCTE-35 messages can be inserted anywhere, and do not need a NULL packet
- If the stream is CBR, the downstream receiver may need a CBR stream. Inserting the SCTE-35 message into a NULL packet ensures the stream will remain CBR; however, it may delay the insertion of the message up to the length of the search window
In the SCTE-35 PID field, specify a specific PID number for SCTE-35 insertion.
If you are using an external POIS or ESNI system, enter the External ID that you use to reference the ZEN Master object in the other system. See the Parameters table below for more information.
In the POIS Latency Offset field, if you would like to offset the POIS modification path to allow for API latency, enter a value in miliseconds. This value can be zero, but it establishes that this output should receive POIS SCTE conditioning.
If you want the timeline adjusted (normalized) to account for insertion and/or removal of SCTE-35 messages, select Make Timeline Continuous (note that the processing will add approximately 100ms to latency).
If you would like to configure advanced settings, click on Advanced and enter values for the desired fields - see the Paramaters Table below for explanations of the fields.

Click Save.
