When Plazamedia decided to move to new 800m2 premises, it was clear that IP technology was the only option to deliver the scalable and future-proof media network the company needed in its facilities. Plazamedia was particularly keen to leverage the potential of IP to transform workflows though infrastructure virtualization, i.e. being able to share studios, control rooms and productions resources (e.g. equipment) more easily, as stated by Nevion.
To achieve this, Plazamedia opted for a spine-leaf, fully redundant, software-defined network (SDN), with Nevion eMerge as leaf switches, Nevion Virtuoso software-defined media nodes as SDI/IP gateways for video, audio and data, and Nevion VideoIPath as the orchestration and SDN control software. The spine switches are provided by Nevion partner Mellanox.
Nevion VideoIPath is the engine of the media network, allowing connections between sources and destinations to be established both in an ad-hoc and scheduled manner, to support infrastructure virtualization in particular. For example, Nevion VideoIPath’s data routing control lets existing commentator-consoles share the back-end equipment via RS-232 over IP, in a way that was not possible until now with the point-to-point physical connectivity.
The NATing (network address translation) capability of Nevion eMerge switches allows Nevion VideoIPath to control media flows to and from any equipment, whether IP or SDI, without the need for specific drivers.
Nevion VideoIPath’s support for the Ember+ protocol also means that operators can manage connections in a production environment through existing and familiar Lawo VSM control panels, used until now for Plazamedia's SDI network.
In addition, the Nevion Virtuosos are being used for to provide essence-based adaptation (TR-04 then SMPTE ST 2110), processing, protections (SMPTE 2022-7) and monitoring of uncompressed video, audio and data in the facilities. In particular, Plazamedia has picked Nevion Virtuoso to provide the audio embedding/de-embedding, shuffling, switching, delay and gain functionality it needed for the new facilities.
Nevion can be found on stand 1.B71 at IBC2018 at RAI, Amsterdam 14-18 September.
