Adding a Source - PID Mapping

You can apply PID mapping to Sources in ZEN Master (for v14+ Broadcasters). This enables you to ensure that the PIDs will have the desired values when they arrive downstream at the Target. This is done by first creating a PID Mapping profile which specifies which PIDs will be processed and defining how they will be handled.

Once you have created a PID Mapping profile you can apply it to a Source in ZEN Master.

This section explains how to create a new PID Mapping Source from an existing Source. This enables you to maintain the original Source with the original PID values. You can then set up multiple Sources with different PID mappings so that you can send differently mapped streams to different Targets.  

Alternatively, you can apply PID Mapping to a standard Source in ZEN Master (Zixi, UDP/RTP, SRT or RIST) by selecting the PID Mapping profile during the Source configuration. This causes the same mapped stream to be sent to all Targets that receive that Source.

The following procedure describes how to add a PID Mapping Source in ZEN Master. In addition, an explanation of each of the configuration parameters is given in the table below.

To add a PID Mapping Source:

1. In the main navigation, click Sources.
2. Click + Add. 
   The Create New Source window is displayed.
   
3. Click on PID Mapping. 
   The Create New PID Mapping window opens.
   
4. In the Info section, in the Name field, enter a unique name to identify this Source in the system.
5. 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 Source 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.

6. In the Events Configuration Profile field, select from the dropdown list the profile that you would like to apply to this Source. 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.

7. The Source'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 Source's IP. If you would like to manually set the location of the Source (Optional), use the following procedure:
   1. Click on the Edit icon next to the Location field.
      A search box is shown below the Location field.
   2. Enter identifying info for the location (e.g. street address, zip code, coordinates).
      Search results are displayed below the search box as you type.
   3. Click on the desired location.
      The selected location populates the Location field.
8. In the Input section, in the Source field, select from the drop-down list the existing Source from which you want to create the new PID Mapping Source.
9. In the Configuration section, in the Ingest Cluster field, select from the drop-down list one of the available Ingest Clusters as the destination for the Source.

10. In the Target Broadcaster/s field, select your Broadcaster preference. Either select a specific Broadcaster to be used OR specify your preference for using primary vs. backup Broadcasters, options are: Prefer Primary Broadcasters, Primary Broadcasters only, Backup Broadcasters only or Prefer Backup Broadcasters.

    For managed clusters, it is not recommended to select a specific Broadcaster, as the Broadcaster's availability may not remain stable.

11. In the PID Mapping Profile field, select from the drop-down list the PID Mapping profile you would like to use.
12. If you would like to generate email notifications whenever a PID change is detected In the Configuration section, select the Alert on PID changes.

13. Select the Log SCTE-35 checkbox if you would like to log SCTE-35 markers for this stream.

    To log SCTE-35 markers, SCTE-35 needs to be enabled both on the Ingest Cluster and on the Source configuration.

    SCTE-35 logging is only available for v13.1.40262+ Broadcasters.

14. If Log SCTE-35 was selected, you can choose to receive alerts for SCTE-35 markers by selecting the Enable SCTE-35 alerts checkbox.
15. In the Public Output field, if you would like to allow access to the stream directly through a supported player, select the Allow checkbox.
16. If you selected the Allow checkbox, then enter a password in the Password field to authenticate access to the stream.

17. If you would like to enable Content Analysis (CQA), verify that the Enable Content Analysis checkbox is selected (default).

    It is generally recommended to enable Content Analysis unless it is causing technical problems. If Content Analysis is disabled, the system won't detect errors in the video and audio content of the stream and won't generate warnings for such events. Even when Content Analysis is disabled the system will still detect TR101 errors in the stream.

18. If you would like to monitor CEA-608/CEA-708 closed captions, select the Monitor CEA-608/CEA-708

    Monitoring CEA-608/CEA-708 Closed Captions requires using a version 14.4 or newer Broadcaster

19. If you would like to disable auto-pull, select the Disable Auto-Pull checkbox.

    Disabling Auto-Pull will lock Channels using this Source to the Source's Ingest Cluster and the Targets to the Source's current active Broadcaster. This setting only applies to Pass-Through Channels.

20. If Auto-Pull is enabled, in the Auto-Pull Latency [ms] field, specify the desired latency for auto-pull actions. (Default: 1000 ms)

21. In the WebRTC Playback section, select the desired playback method.

    WebRTC enables you to monitor the stream via web browsers and mobile applications with real-time communication (RTC). WebRTC needs to be activated independently for each Source in ZEN Master (by default it is disabled).

    
    Select one of the following options:

    • Disabled - users will not be able to view this Source using WebRTC (default)
    • Pass-Through - passes the stream through to WebRTC without transcoding. This option can only be used if the input stream is already in a WebRTC compliant format (video - H.264 codec with Baseline or Main profile and no B frames, Audio - Opus codec).

    • Auto - ZEN Master automatically transcodes the stream using the optimal profile for each specific user. In this option Zixi Broadcaster will decode the video, transforming it into RAW frames, which will be passed to the WebRTC library, where it will be re-encoded for each individual user.

      Best quality. However, if monitored by multiple users this can consume extensive resources.

    • 1080p/720p/480p/360p - ZEN Master transcodes the stream to a WebRTC compliant  profile with the specified resolution. The transcoding is done by Zixi Broadcaster's transcoder.

      This method requires a Zixi Broadcaster with X264 or Nvidia for transcoding. This method allows many users to monitor the stream without encoding separately for each individual user, which saves CPU capacity. Since there is only one stream version, it is recommended to encode to a low resolution and low bitrate so that the stream will be viewable by all users monitoring the stream.

22. In the Initial State section, select the Disabled checkbox if you would like to disable this Source upon initial configuration.

23. Select the Muted checkbox if you would like to disable error/recovery notifications for this Source upon initial configuration.

    You can Enable/Unmute the Source at any time.

24. If you would like to adjust the advanced settings, click Advanced.
    The Advanced settings fields are displayed:
    
25. If you would like to track usage for this Source, enter your Billing Code details. See Billing Codes.
26. In the Auto Pull MTU field, specify the maximum transmission unit (largest data packet that a network-connected device will accept) in bytes for the Auto Pull.
27. To apply Input NIC selection to the network device, select the Apply Input NIC selection to network device checkbox.
28. To set the detection of frozen video, in the Frozen Video Minimal Duration field, specify the default minimal duration in seconds of frozen video after which the Broadcaster will trigger a Frozen video alert. Default: 10 seconds. This setting is supported for Broadcaster version 16.3 and higher. 
29. To set the detection of blank video, in the Blank Video Minimal Duration field, specify the default minimal duration in seconds of blank video after which the Broadcaster will trigger a Blank video alert. Default: 10 seconds. This setting is supported for Broadcaster version 16.3 and higher. 
30. Click Save.
