Swedish streaming service Viaplay has modernised and expanded its Warsaw studios, installing Lawo mc²36 and diamond mixing consoles, and Ravenna/AES67-native IP infrastructure products.
Headquartered in Stockholm, Viaplay airs sports, comedy shows and movies. After inking a new contract with production companies Ekstraklasa Live Park and the ATM Group, and with the recent expansion of services beyond the Nordic region into the Baltics, the Netherlands and Poland, Viaplay undertook a major technical upgrade to ensure the reliability of service demanded by simultaneous transmission of many separate sporting events.
LP Systems, Lawo’s partner in Poland, was chosen to implement the audio portion of Viaplay’s studio update. ‘The project is designed as a fully IP-based infrastructure,’ says Sales & Support Engineer, Artur Jóźwik. The project’s scope included two new studios with separate control rooms for audio and video, as well as 12 sports commentator booths with six separate small audio control rooms. The massive technical upgrade was performed during June and July 2022, to be ready in advance of fall sporting event coverage.
For the main audio control rooms, two Lawo mc²36 all-in-one production consoles where chosen. Compact yet flexible and powered by Lawo A__UHD core technology, mc²36 consoles can be sized from 16 to 48 faders and feature intuitive guided workflows, and the A__UHD cores each provide 256 DSP channels, 48kHz and 96kHz operation, and 864 channels of I/O capacity. IP-native with support for all relevant standards, they also feature redundant power supplies and ST2022-7 ‘hitless merge’ network link redundancy demanded by live broadcast operations.
‘All microphone inputs, sums, aux lines and other signals are transmitted as Ravenna/AES67 streams; only the speaker connections remained analogue,’ says Jóźwik. ‘It’s a very flexible solution that enables Viaplay to combine any studio with any control room at any time. Everything works together seamlessly, without any additional routing.’
More flexibility is provided by Lawo VisTool software, which allows creation of customisable, context-sensitive mixing tools for multi-touch displays. All of Viaplay’s diamond consoles are equipped with dedicated all-in-one PCs running VisTool, which power their Virtual Extension touchscreens. This enables operators to visualise EQ curves, compression settings, DSP functions, routing setups, and even integrate control of third-party software and devices.
All IP-native Lawo devices are connected and managed within the network by the Home management platform for IP-based media infrastructures, using web interfaces with standard browsers. The Ravenna/AES67 audio network is underpinned by Artel Quarra switches, which are configured to provide a fully redundant networking environment. Integration with video systems is via DirectOut Prodigy.MP processors in mirror mode for full system redundancy. These devices convert Ravenna signals to Madi and vice versa, and help facilitate final processing.
‘Working closely with ATM Group’s engineers, we achieved all of Viaplay’s goals and desired system functionalities,’ says LP Systems Sales & Support Engineer, Bartosz Stawiarski-Lietzau. ‘Along with the VisTool controls in the audio control rooms, an additional VisTool computer is installed in the Master Control Room for quick access by the engineer. All of the Power Core units and diamond surfaces can be monitored, diagnosed and controlled there, with audio streams monitored using Lawo Rǝlay AoIP Stream Monitor software.’
The ability to tailor Lawo solutions to specific needs was extremely important to Viaplay, notes Stawiarski-Lietzau. ‘Like all complex broadcast operations, Viaplay has highly refined operational requirements. To meet these requirements, we needed to adjust the functions of mixing surface keys, customise control screens and match system functionality to workflow expectations. Lawo, with their intense focus on flexible, customizable solutions, made it easy for us to meet – and exceed – customer expectations.’
