The following updates were pushed to ZEN Master on January 13, 2020.


Improvements



### Dynamic Zixi Pull Targets


Most useful for occasional use and live events, ZEN Master now provides the ability to create a
single “Dynamic” Pull Target in ZEN Master that is automatically connected to multiple Receiver
devices without needing to define a Target for each Receiver device individually. This feature
provides a live video MeetMe room capability to simplify distributing live content to different
organizations on an event by event basis.
To create a dynamic Pull Target, simply select “Dynamic” on the Target.
On the Targets list you will now see that dynamic Target you just created.

Next supply the stream parameters to organizations with Zixi Receivers that will Pull the
stream.
Once Receiver devices connect to the Target’s Host/Port/StreamID, they will be listed in the
Targets list and in the Child Targets section on the Target detail page.
Child targets are named using the parent Target name and the ID of the Zixi Receiver. For a
standalone Zixi Receiver the ID is changed in Settings->General.

For Zixi Receiver integrations in IRDs and other devices, the ID would be defined in the device
UI or may be automatically defined. Note, all Receiver devices Pulling from a single dynamic
Target must have unique ID’s. If you want to Pull a Channel into a Receiver twice for
redundancy, you will set up two dynamic Targets connected to the same Channel and then Pull
from each dynamic Target.
Child Targets are not editable; they assume all of the settings of the parent Target and can only
be deleted. However, you can release a child Target from its parent, as shown below, and then
it can be edited as it no longer assumes the settings of the parent.
Deleting a parent Target will also release all child Targets to be regular Targets; deleting a
parent Target does not delete child Targets and thus causes no stream disruption.
If the Channel of a parent Target is changed, this will only affect newly connected child Targets
after that change and will not disrupt existing child Targets. To change the Channel on multiple
child Targets, change the Channel of the parent and then select the desired child Targets in the
Target list and delete them. They will then reconnect and assume the new Channel setting
from the parent Target.

### Boolean Search


Filter fields in ZEN Master now support Boolean operators AND, OR, and NOT to simplify
filtering the visible objects. The ( ) \[ ] characters are also supported for grouping the Boolean
expressions. Filter fields are available on object lists, such as Sources or Broadcasters,
and on Grids.
As before, filter fields are sticky such that filter expressions previously entered will remain
when returning to previously browsed pages.


### Automatic Clustering of Objects on Maps


Objects on maps will now be clustered based on zoom level of the map so that multiple objects
in one area will not overlap. The icon for the clustered objects shows the number of objects in
each state in the order OK, Warning, Error, and Offline. For example, “2/5/4” as shown in the
image on the left below shows that 2 objects are in OK state based on the green color, 5 objects
are in Error state based on the red color, and 4 objects are in offline state. The image on the
right shows the objects with clustering turned off.

Clustering is automatic based on zoom level but the user can also manually uncluster objects
using the button shown below.


### Show/Hide List Columns


The user can now select which columns to display on lists such as the Sources list or Channels
list. This can be useful on devices with smaller screens, such as phones or tablet, or just to
remove unnecessary information from the page. The column setting is sticky meaning that
when you browse away from the page or log out of ZEN Master and then come back to the
page, the same columns will be enabled and disabled. The settings are stored on a per browser
basis such that the browser on your tablet might have certain columns enabled and disabled
while the browser on your laptop would have different columns enabled and disabled. The
column selector is next to the Filter box as shown below.

Included below are additional improvements in this ZEN Master release:
• System wide performance upgrade
• Auto-pull latency on Sources is now configurable
• Added Search Window and Merge Mode on Hitless Failover Sources
• Broadcaster thread priority is now low by default on AWS/GCP/Azure clusters

• GCP targets now have Cache-Control headers automatically set to allow playback
directly from GCP Storage
