Telos VXs Virtual VoIP System for Television

Powerful and adaptable Voice over IP virtualized system for broadcast and live TV production

Telos Alliance first introduced broadcasters to the benefits of VoIP a decade ago, with our first VoIP phone system, Telos VX®. VX replaced racks of phone couplers, contribution hybrids, and engineering coordination lines with a single hardware VoIP Engine. Now, Telos VXs is here to help broadcasters reap the benefits of true virtualization as they adapt to changing broadcast workflows, all while making it easier for remote teams to tap into production and engineering partylines.

From remote IFBs to audience call-ins, VXs can run anywhere from one or two lines in a small studio to the on-air phones for your entire plant, giving you incredible operational power, adaptable workflows, and superior audio quality.

Production facility design is evolving, moving away from dedicated hardware connected to centralized router frames to flexible SMPTE 2110 media networks with software-based workflows. VXs software can be deployed on shared servers in the centralized data center or in cloud instances. These deployment options enable the benefits of true virtualization, such as easier facility-wide upgrades, automated deployment, and more, without site visits. Broadcasters can scale VXs in size from a single contribution audio line to a facility-wide IFB system to a multi-facility system, meeting the exact needs and budget of the facility now, with the ability to upgrade at any time with no penalty.

For decades, phone-based IFB and comms have been neglected in video production facilities. Instead of treating these critical communication paths as invisible background connections, VXs allows these assets to be brought to the forefront for detailed monitoring and control via customizable Pathfinder HTML-5 user panels for applications such as OB Truck to HQ Comms. 

Standards-Based for Easy Connectivity

Support for SMPTE-2110 and AES67 environments brings a new level of compatibility and flexibility to VXs, allowing for direct integration with intercom systems, audio consoles, and other production systems over existing multicast media networks. Support for SAP advertisement means VX smoothly integrates alongside AES67-enabled Dante® devices, as well. 

When combined with the Telos Infinity™ IP Intercom system, the drag-and-drop Infinity Dashboard interface allows remote IFBs and engineering coordination lines to be centrally configured, added to partylines and groups, and assigned to Infinity IP Intercom panels quickly. 

For those without an IP media infrastructure, Telos Alliance AoIP Audio Nodes provide high-density AES3, SDI, and analog I/O to integrate with any console or intercom system now while providing an upgrade path to direct AoIP connectivity as your facility evolves in the future.

New-to-AoIP Installation 

Don’t have IP-Audio networking yet? VX will work with all console and intercom brands, networked or not, using Telos Alliance Nodes with AES3, SDI, and analog I/O, as well as GPIO.

The diagram above shows an example system with a non-AoIP mixer and intercom system using a Telos Alliance AES xNode and SDI Node.

Support for Livewire+™ AES67, AES67, and SMPTE 2110-30 environments brings a new level of compatibility and flexibility to VX VoIP systems. Support for AES67 gives broadcasters the capability of integrating VX into any AES67 environment or compatible SMPTE 2110-30 environments. Support for SAP advertisement means VX smoothly integrates alongside AES67-enabled Dante® devices.

HTML-5 Control

When combined with Axia® Pathfinder™ Core PRO Broadcast Controller, you can create touchscreen-friendly custom HTML-5 panels to monitor and control every aspect of the VX system from any web browser. Comms managers and producers can use panels to manage all the IFB, contribution, and tech coordination lines in the facility. Gone are the days of reporters calling in to the wrong IFB and missing their live shot. With an HTML-5 control panel, producers can see the status and caller ID of each IFB line and even have the ability to call the reporter directly. 

High-Performance Audio

Every call gets 5th-generation audio processing, packed full of technology engineered to extract the cleanest, clearest caller audio from any phone line—even noisy cellular calls. VXs makes TV talents’ in-ear and comms feeds more intelligible as well. It includes Smart AGC coupled with Telos’ three-band adaptive Digital Dynamic EQ, a three-band adaptive spectral processor, noise gating, and Acoustic Echo Cancellation. 

HD voice calls will benefit from VX’s native support of the G.722 codec, instantly improving speech quality.
