The following updates will be included in the ZEN Master November 30, 2021 release.


Features



The following new features were implemented in this release:
• Added ability to define and view Incidents on Channels in ZEN Master. An Incident is
defined by a user selected time range and includes time/user-stamped notes. The
Incident view allows the user to select or “pin” multiple history graphs and event logs
for objects in the Channel and view them together on a single page synchronized to the
time range for the incident. The Channel diagram is displayed as well on the same page.
An example is shown below.
• Added diagrams to Sources, Feeders, and Receivers. Channels and Targets included
diagrams previously.
• Added ability to create MediaConnect Sources from Elemental Link encoder devices
• Added support for failover based on TR-101 and CQA errors. Previously, the user could
specify parameters for a rule for zero bitrate streams to trigger a switch to another
Source in a good state. Now the rules for that failover are expanded to include TR-101
P1 transport errors, Frozen Video, Blank Picture, and Silent Audio. This feature applies
to non-identical Sources merged hitless failover is not in being used. Broadcaster v15.0
is required.
Additional Improvements
The following additional improvements were implemented in this release:
• Added support for Broadcaster v15 transcoding updates to NVIDIA CUDA 11.4 and driver
version 470.

• Added support for HRD buffer fractions in the transcoding profile
• Improved DTLS redirection support
• Added sticky multi-selection after an operation such as enable/disable or mute/unmute
• Added UDP send errors to Target graphs for UDP, Zixi Pull, and Zixi Push
• Added Disk usage column to Broadcaster list in Broadcaster cluster
• Added a Broadcaster "restart required" confirmation when applying Broadcaster
configuration that will require a restart that results in a stream interruption
• Clarified status display of AWS Broadcasters terminated by AWS
• Updated list of supported AWS regions to include recently added regions
• Added disable checkbox for Source - Analysis - TR101 P2 in Event Profiles
• Added an alert when a Source is connected to the wrong Broadcaster in the same
cluster
