Tieline ViA Duo
Redefining Broadcast Workflows
ViA Duo is the new generation of trusted ViA technology that truly bridges the gap between field reporting and commentary. Built for reporters and commentators alike, it is an ultra-portable broadcast platform that can operate as an IP codec, AoIP commentary node, or facilitate off-tube broadcasting through support for audio and video feeds.
Simply take the codec to the remote site, power it up, and connect to your preferred network and start broadcasting. There’s no need for additional outboard gear like mixers, equalizers, compressors, noise gates, expanders, recorders and playback machines – with ViA Duo it is all-in-one and ready to go!
ViA Duo supports HDMI video out, multiple AoIP protocols, plus IP streaming over multiple interfaces. It delivers an all-in-one solution consolidating your remote broadcast, commentary and off-tube broadcasting requirements into a single compact and lightweight box. It is ideal for:
- Reporters to use with a guest
- Two commentators broadcasting sports events
- Announcers working from home
- Talk show and other radio show hosts on the road
- Off-tube commentary, or use as a sports commentary unit over AES67, ST2110-30, Livewire, RAVENNA, or Dante (AoIP and Dante card is optional)

Ways To Benefit From ViA Duo
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.
