Singapore terrestrial broadcaster Mediacorp has installed 50 copies of Lawo’s RƎLAY VRX4 virtual radio mixer software to power an open workspace concept that allows reporters, producers and talents to create content at dozens of production workstations.

IP transformation starts with audio

In terms of the IP transformation sweeping the broadcast and media industry today, audio has arguably surpassed video in terms of audio-over-IP (AoIP) networking technologies, media transportation and, of course, interoperability.

As the primary distribution approach of digital audio signals across an IP network, audio-over-IP (AoIP) has been increasingly embraced by the installed sound, live, radio and broadcast industries. One standard that has emerged to enable AoIP streaming is AES67, which was published by the Audio Engineering Society (AES) in September 2013.

AES67 empowers interoperability between the various IP-based audio networking products, based on existing standards such as Dante, Livewire, Q-LAN and Ravenna. Although AES67 is not a new technology, it is a bridging compliance mode common to all IP networks that operate over standard Layer 3 Ethernet networks, and is routable like other common modern IT networks.

The new media centre in Mediacorp hosts facilities for 12 radio and eight TV stations, as well as where a number of online streaming channels originate. The centrepiece of the new facility is a central newsroom, which is designed around an open workspace concept that allows reporters, producers and talents to create content at dozens of production workstations.

To power these workstations, the Singapore terrestrial broadcaster installed 50 copies of Lawo’s R3LAY VRX4 virtual radio mixer software. Each computer is connected to the facility’s AoIP network, giving each workstation’s R3LAY mixer access to audio from network-attached devices such as playout computers, codecs and voice-over-IP (VoIP) servers, as well as audio from local sources.
