What's new in Infinity version 23?

This post covers the new features and functionality in Pexip Infinity (self-hosted) version 23: 

  • One-Touch Join for Cisco endpoints 

  • Adaptive Composition feature preview 

  • Media enhancements 

  • Firewall and network enhancements 

One-Touch Join for Cisco video endpoints 

Joining video meetings can be tricky with dialling various numbersURIs or IP-addresses. A frequently requested feature from our customers has been integration with their primary calendar, such as Microsoft Exchange (on-premises or in Office 365) or Google Calendar (G Suite). Starting with version 23, this feature is now built in (requires license key)

One-Touch Join allows the Pexip platform to access your calendar meeting room resources and enables scheduled meetings to appear as a green join button. When the meeting is ready to start, the button appears on your video endpoints (list of supported models here)

Push One-Touch Join

 → For end-users, this feature makes joining meetings even easier. They simply need to invite their meeting rooms to the video meetingsIt will be simpler than ever to join meetings on time with just the push of a button no manual dialling needed 

For administrators, it’s a one-time set up (with a minor addition for new video systems) to activate Cisco devices.  

Since the One-Touch Join solution runs in the customer’s network, the highest standards of data privacy have been taken into account. The integration reads room calendar data and pushes it to the video endpoints. The calendar data is never processed by Pexip or other external 3rd parties. The sensitive company data that’s often contained in calendar invitations remains completely in the customer’s network.

The One-Touch Join capabilities are available for Pexip Infinity self-hosted and Service customers. Existing Pexip Infinity customers simply need to add a license key and configure the feature, while Pexip Service customers will need to install the solution and configure it. Pexip has a professional services team and partner network ready to assist with any installation or configuration.

Adaptive Composition 

Video conferencing has improved a lot over the last couple of years, but one area that has not changed is the traditional video layouts in our meeting rooms and personal clients.

Pexip’s Adaptive Composition is a sneak peek into our work with Artificial Intelligence (AI). Adaptive Composition leverages AI to identify the number and placement of participants in a room and then use this information to create optimized framing. It also gives additional screen real estate to larger groups of people. This allows participants to have more natural and engaging contact with everyone in the meeting.

The key concepts of the Adaptive Composition feature preview in v23 are: 

  • Participant detection: Finds out how many and where in the room people are. Pexip will never track who’s in the meeting room. In order to respect participant privacy, we do not use facial recognition technology. 

  • Participant auto-framing: We are actively zooming, panning and tilting where the camera might not be optimally adjusted. If people join or leave the room, the system adapts and recomposes the view of the participants.

  • Intelligent Composition ensures optimized use of screen real estate putting rooms with many participants in the larger, higher area, and single participants further down – instead of the more traditional experiences where a room full of people is demoted to a small image or removed from view while not talking.  

Adaptive Composition is achieved with a combination of transcoding and AI so all optimization happens on the server side.  This means that the feature is available for ANY client and system that can connect to a Pexip Meeting.

Media enhancements 

There are also several media enhancements done in Pexip v23 allowing customers to take advantage of the latest functionality in their meeting room systems, browsers and clients. 

Key areas to mention here are: 

  • Granular 1080p control: Allows administrators to set individual virtual meeting rooms (VMRs) or gateway calls to 1080p mode, where previously this was a global on/off setting in the platform. 
  • Granular presentation bandwidth usage allows administrators to adjust what % of the call bandwidth should be allocated to the presentation in a video meeting on their platform. With single screen video rooms, you may prefer to allocate the majority of the bandwidth to the presentation while it is being shared – but if you have dual screen systems, you may prefer a more equal split.
  •  Full VP9 support, allows administrators to fully enable VP9 on their Pexip platform, taking advantage of a stronger compression (lower bandwidth for the same quality or higher quality at same bandwidth) at the cost of higher CPU usage. This is available for customers with Conference Nodes supporting AVX2 instruction sets (most servers from 2015 and later). Today, VP9 is supported as a standard feature for users of Google Chrome browser, and the Pexip Infinity Connect clients.

Firewall and network enhancements 

  • Firewalls are present everywhere in corporate networks, and in some cases, additional features might be required to ensure video works in corporate networks. 
  • The ability to fall back to transport audio/video and content from web browsers supporting TCP-based media is added as a Tech Preview feature in this release, where administrators can enable the option of falling back to port 443/TCP if media could not connect over the normal UDP ports. 
  • For large enterprises, the Pexip platform deployed internally on their network might not be able to communicate with the internet unless passing via proxy servers. Response to issues such as, license activation, incident reports and access to anonymous statistics that previously required offline interactions. This release introduces proxy support to simplify the administrators job and enables a more proactive and agile support flow in case of incidents.

Microsoft Teams improvements

  • The Virtual Machine Scale Set disks are now encrypted by default, and access keys for the storage account are moved to Azure Key Vault and regenerated every 90 days. 

  • Improvements in media quality in particular for presentations. 

  • Improvements in the deployment scripts for the Pexip for Microsoft Teams Connector to help  with certificate-related issues.  

  • Teams users will now show up as name@domain format where previously they would just show an ID. This is a subtle but welcome improvement for administrators and support personnel using the Pexip Management interface. 

In addition, v23 includes multiple improvements for customers with a large number of conference nodes, concurrent calls or meetings and customers using the Pexip Infinity Connect web app and clients will benefit from performance improvements to ensure lower CPU usage for clients.
