AoIP Capacity Increased On Nevion Virtuoso And VideoIPath Ranges

Nevion has added increased audio over IP (AoIP) and audio processing capability to the software for its Virtuoso media node and VideoIPath products. The announcement was made during the recent 2018 NAB Show, where the two systems were presented as a single routing application for IP-based sound and video used in facilities and on location.

Virtuoso was designed by Nevion as a software-configured media node handling multiple input and output formats. These include SDI and SMPTE ST2022-6 and ST2110 on the video side and AES67 for audio, with the unit having the capability to convert, route and process individual audio channels. VideoIPath is an orchestration and SDN controller, which brings together routing and processing of both composite - SDI and ST2022 - and essence - AES67 and ST2110 - streams.

The new software release increases the range of features on Virtuoso to include synchronisation, embedding, de-embedding, mono shuffling, audio delay and gain control, on a channel-by-channel basis. The total of ST2110-30 (AES67) RTP (Real-Time Protocol) audio paths has been increased so that all audio is now routed in its native form over IP. For example, mono is carried as one channel while stereo is on two-channel streams. Further additions to the software will be made in the future, including conversion of MADI to ST2110-30, support of Dolby E transport streams and audio embedding as laid out in the draft SMPTE ST2110-31 standard.

VideoIPath can be used for audio essence flows as well as video flows, both over IP networks. It can work as an interface for any broadcast control system running the Lawo/L-S-B Ember+ protocol or RESTful API (application program interface). This allows control units already on the system to manage signals together with management of Virtuoso endpoints.
