Telos to show VX Talkshow System at BIRTV

The world’s first multi-studio VoIP phone system for broadcast

20 August 2010, Cleveland Ohio, USA

Telos Systems, the industry leader in radio broadcast telephony, will present the world’s first multi-studio VoIP Talkshow System for broadcasters in Asia at BIRTV in Beijing.

Telos VX system is based on VoIP (Voice over Internet Protocol) technology. Phone lines are shared throughout the broadcast plant, and system components are easily connected, via Ethernet cable. VX uses standard SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) protocols, so it works with VoIP-based PBX or SIP-trunking Telco service to direct up to 80 lines of phone traffic.

VX is scalable to provide advanced phone interface capabilities to a few studios, or dozens. A variety of control options allow talent, producers and board ops to choose multiple phone, console and software interfaces: The new VSet12 phone controller offers a familiar phone-set design and big, bright, color-LCD display to talent and producers, while VX Producer call-screening software, with a built-in soft-phone, turns any PC into a phone station. And direct integration with Axia IP-Audio consoles lets talent make and take calls directly from the board. Each Vx Engine supports up to 100 control devices, in any combination.

"Integrating VoIP into the mixing console allows both to work together seamlessly, which means better interaction with callers and expanded program-production capabilities," explains Steve Church, CEO of Telos Systems. "Now a single VoIP console module can replace several digital phone hybrids and simplify call screening. VX is designed to bring broadcast content closer to the style of social media and ‘Web 2.0’ applications that provide rich interaction between talent and audience."

The VX system includes:

Vx Engine - Call control and audio processing engine

  • Telos Hx1 and Hx2, are designed to tame and sweeten today’s most chaotic calls - from even mobile phones. Telos’ most advanced hybrid algorithms, added DSP power and several other new features essentially make the Hx1 and Hx2 a new breed of hybrid.

Telos has been innovating telephone systems for broadcasters since 1984, on the cutting edge of technology in VoIP phone systems, hybrids, IP/POTS/ISDN Codecs, broadcast software and streaming.
