ZEN MASTER November 2021 RELEASE NOTES

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

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

The following issues were resolved: • Fixed RIST targets not configured correctly on Broadcasters • Fixed issue creating Broadcaster Sources with manual bonding • Fixed issue with Broadcaster losing virtual GPU after GCP maintenance event • Fixed an issue causing ZEN Master to try to create redundant Target configs on the same Broadcaster • Fixed intercluster Sources requiring a restart after an edit to apply the new configuration • Fixed ‘Sources Create’ API endpoint requiring that an Event Profile to be specified • Fixed AWS Broadcasters launching with no name • Fixed DNS redirect issue with SRT Targets • Fixed issue with being unable to disable MediaConnect Channels using Automation • Fixed issue with Broadcaster restarting unnecessarily when applying Broadcaster configuration • Fixed an issue preventing Broadcaster GPU usage from showing up in the Broadcasters table • Fixed issue with not reporting SCTE-35 messages with UPID 0 "Not Used" • Fixed issue with not cleaning up no longer required auto-pulls • Fixed issue incorrectly configuring PID Mapping in some edge cases • Fixed UI issues with PID Mapping Match PCR to Video PID
