Stadium TV Commentary

The ViA Duo can be used in a variety of broadcast commentary roles for radio and TV broadcasts. Optional support for AoIP protocols like RAVENNA, Dante, AES67, ST2110-30, Livewire and NMOS facilitates using ViA Duo as an AoIP node in stadium commentary booths or on the sideline. Flexible options include connecting over a LAN to a remote truck at a venue, or over a WAN with a REMI (Remote Integration) use case back to a mixing console at a studio hub.

Off-Tube Commentary

ViA Duo supports off-tube commentary so your commentary team can get a live game day feed and call live from wherever they are in the world – even from the comfort of their own home. You can even use the codec at a stadium and receive a video return feed from the studio including stats and other live or recorded elements of the broadcast. Paired with a real-time mix-minus comms feed, your commentary team will get the full picture.

Radio Commentary using Dante

ViA Duo seamlessly integrates with existing analog and AES3 digital infrastructure with optional support for Dante to deliver unprecedented flexibility for radio remotes. Featuring functionality for one or two commentators, you can also integrate Dante audio in/out to expand production possibilities. For example, use ViA Duo to integrate with other equipment like mixers, sound effects mics and more, and send full duplex stereo program audio back to the studio.
