QG-FBSR52K — 4K AV-over-IP Decoder Node

Why QG-FBSR52K

4K60 Decode

H.264 / H.265 hardware decode at up to 4K60. HDR10 / HLG pass-through for cinema-grade image quality.

Native Video Wall

Up to 16×16 video walls from any combination of decoders. Bezel compensation, picture-in-picture, multi-view built in.

PoE+ Powered

One Cat6 cable carries decoded video, audio, control and power. Clean ceiling and rack installs.

Dante / AES67 Audio

32-channel Dante endpoint — pair with QG-FBST52K encoders for a full Dante + video network on one switch.

Far More Accessible Cost

Same functional scope as Extron / Crestron AV-over-IP decoders — at approximately a fraction of the procurement cost.

3-Year Warranty

Every QG-FBSR52K ships with a 3-year manufacturer warranty and lifetime firmware updates.

Deployment Scenarios

ADHOOPU distributed AV over IP command center — QG-FBST52K encoders, QG-FBSR52K decoders and IMC control on one 1GbE network — **Command Center** — any source on any screen · KVM over IP · video wall tiling

ADHOOPU distributed AV meeting floor — one encoder per source, any source on any display — **Meeting Floor** — one encoder per source · any source on any display · no re-cabling

ADHOOPU distributed AV multi-building campus — campus-wide AV over IP on the existing 1GbE backbone — **Multi-Building Campus** — campus-wide AV on the existing 1GbE backbone · no new fibre pulls

ADHOOPU distributed AV system architecture — encoder, 1GbE switch, decoder, decentralised no-server fabric — **System Architecture** — encoder → 1GbE switch → decoder · decentralised, no KVM server

Where QG-FBSR52K Is Used

Command Center Video Walls

Each decoder drives one panel of a 4K video wall — any source, any layout, with sub-second switching.

Corporate Wayfinding Displays

Each lobby / floor display gets a decoder pulling live signage, dashboards or TV channels.

Hospital Operating Theatres

Multi-modality imaging on every OR display; KVM returns from radiology PACS.

Broadcast Studios

Multi-view monitor walls, talent monitors, confidence monitors — all decoded from a central switch.

Frequently Asked Questions

Does QG-FBSR52K require a controller?

For basic point-to-point (one encoder to one decoder) no. For matrix switching (any-to-any) and video wall layout, the QG-FBST52K / QG-FBSR52K controller is required. The controller is free with a project license.

Can I mix QG-FBST52K and QG-FBSR5K on the same network?

Yes — the QG-FBST5K / FBSR5K pair uses the same control protocol. Backwards-compatible with all existing QG distributed deployments.

What about latency?

End-to-end glass-to-glass latency at 1080p60 is typically 70–90 ms — visually indistinguishable from direct cable for video wall, signage, classroom and meeting room use. For broadcast-grade production switching, our direct-fibre QG-4U1616 is recommended.
