ZEN MASTER January 2022 RELEASE NOTES

The following updates will be included in the ZEN Master January 26, 2022 release.

The following new features were implemented in this release: • Insights view in the Intelligent Data Platform (IDP) o Infrastructure Insights identify outliers among various operating parameters on Zixi Broadcasters, such as memory and CPU, that impact video delivery. o Channels Insights identify network anomalies on Sources and Targets that impact video delivery. • Management of Zixi Edge Compute (ZEC) endpoint devices. More details on ZEC devices are coming soon. • Dark mode across whole ZEN Master site • Multi-edit for Tags and Event Profiles. The user can now multi-select objects and edit the selected objects to overwrite, add, or remove Access Tags. The user can also multi- select objects and update the Event configuration profile used for those objects. • CDI & JPEG-XS Sources and Targets in AWS MediaConnect Flows • Maintenance mode for Broadcasters that prevents new streams from being assigned to that Broadcaster. This feature might be used in the following scenarios: o Scheduling a Broadcaster to be taken out of service for maintenance or upgrade o Adding a new version of a Broadcaster to a cluster for testing and validation prior to enabling production usage o Adding a Broadcaster to a cluster where necessary configurations on the Broadcaster, such as firewall setup, are still pending • Primary/Backup Sources on Pass-through Channels with Source preference selection on Targets

The following additional improvements were implemented in this release: • Updated Transcoding Channel output paths on HLS origin servers to remain constant even when moving the Channel between Broadcasters or Clusters • Updated sorting by status to be consistent across all object types • Improved time to first connection when using Pull targets on clusters with multiple Broadcasters • Added alert on missing CEA-608/708 closed captions on Sources • Added API key name to API logging for better visibility • Added the display of active Source to Targets on diagrams and Source type to Sources on diagrams • Added field for Maximal DTS-PCR delta on transcoded CBR Sources • Added FFA authentication support for RTMP push Sources • Added support for selectable NIC on RTMP Pull sources

The following additional improvements were implemented in this release: • Added indication on Source detail page when RTP headers are included on Zixi sources • Added display of declared bitrate and HRD buffer size in TR-101 data • Added radio selector to enable CBR by padding mode for UDP/RTP and RIST Targets • Added estimated VMAF history graph for Sources • Updated audio transcoding profiles to apply to all audio PIDs

The following issues were resolved: • Fixed multiple issues with diagram rendering • Fixed SCTE reporting errors • Fixed issue not being able to choose port auto-select for RIST Pull Source • Fixed multiple issues when using Monitor Only Sources as inputs for other Sources • Fixed issue with packet delivery % graph showing bitrate in % instead of kbps • Fixed API timeout issues between ZEN Master and Broadcasters causing inconsistent states when configuring Channels • Fixed issue with SCTE35 graphs on Sources not showing any data • Fixed SRT graphs showing bitrate in hours instead of kbps • Fixed issues with diagrams not loading for users that have partial permissions on objects • Fixed issue with pass-through Channels with no Targets reporting missing Source errors • Fixed issue with Events configuration profile is not being displayed on the Cluster detail page or the Broadcaster detail page • Fixed issue with Push Targets to MediaConnect • Fixed issue with MediaConnect Pull Targets only working for first connected device • Added appropriate error messages for WebRTC playback issues • Fixed error when adding AWS Account • Fixed issue with "target not found in cluster" errors • Fixed “unexpected error” issue HTTP Target history graphs • Fixed issue with missing alert notification emails
