A small one-paragraph blurb in the InfoComm 2018 Show Daily is the biggest story of the show – Audinate announces Dante AV. A perfectly timed article, “Making the Case for AV-0ver-IP,” in the June 2019 Sound & Communication magazine, written by Audinate’s Brad Price, reveals a bigger picture.
The short story is this – Dante AV accepts up to 4K60 4:4:4 10-bit video and 8 audio tracks, routing AV streams over 1G IP as easily as Dante audio, all in sync with a master clock. Audinate makes the new Dante AV interface that’s inside, and other vendors add Motion JPEG 2000 encoding/decoding as well as pass-through RS-232 and IR. Network routing, discovery, master clock, and control is handled by Dante, with assured interoperability between suppliers’ transceivers.
The bigger vision for the new innovation is presented with clarity in the article, written before Dante AV was revealed at the show. AV-over-IP has great potential, but as in the early days of network audio, manufacturers have created a mish-mosh of choice, an irregular, branded mix of codecs, networking schemes, control commands and proprietary features. Pixel Perfect vs PURE3? What does that even mean?
For the AV-over-IP to grow, a consistent standard is required. To meet the needs of both the AV and IP communities, a standard must be set that answers requirements for security, scalability, interoperability, performance, and market adoption. An ecosystem made of many partners offers more options than domination by one brand, or niches owned by a few.
For many reasons, AV-via-Dante can be a strong foundation for that ecosystem. After all, they did emerge as the defacto standard for IP audio – why not AV?
Crestron is the market leader for many good reasons, but Dante-friendly Q-Sys programming is quickly gaining ground. Other major players will arise shortly – Yamaha is already an Audinate AV partner, with products in development. As Crestron plays well with other standards, they could incorporate Dante AV as well.
However all this plays out, Dante AV should open the door to new innovation in AV-over-IP!
