Nevion’s Virtuoso is a standards-based, virtualization-ready, software-defined media node that can perform a variety of real-time transport, processing and monitoring functions in the converged IP LAN/WAN network. With its functionality easily modified in the field through software, Nevion Virtuoso enables a faster time-to-production and greater cost-effectiveness.
As well as its comprehensive video capabilities, Virtuoso also provides advanced audio media functions. These include adaptation and routing between AES3, MADI and IP audio (SMPTE ST 2110, AES67), as well as audio processing functions such as embedding/de-embedding, shuffling, gain and delay control.
A new digital audio card for Virtuoso, designed specifically to optimize the support for AES3, offers breakout panels that have either 16x BNC or XLR ports, and supports input sample rate conversion, making it easy to use in SMPTE ST 2110 systems.
The audio processor capabilities of Virtuoso have also been enhanced with a new low-latency audio mixer functionality. The audio processors can now be configured in matrix mixer mode supporting summing of any input audio source. Matrix sizes are highly flexible and configurations range from 8x8 and 16x4 up to 24x20, 16x32 and 64x8. Audio processing is supported on the input stage of the mixer as well as on mixer cross-points.
While the mixer capabilities of Virtuoso do not replace a studio or production mixer, they provide useful functionality for simpler audio mixer and mix-minus capabilities in radio and television production applications.
The Virtuoso’s audio media functions have been selected and deployed by several television and radio broadcasters, for various applications. For example, they are being used as part of a SMPTE ST 2110-based nationwide network connecting regional broadcast studios and event sites, and a radio production and distribution network.
