QG-FBSR52K — 4K AV over IP Decoder for Video Walls & Multi-Screen Display

Q: Can multiple decoders form a single video wall?

Yes. Multiple QG-FBSR52K AV over IP decoders can be coordinated into one logical video wall over IP, with source windows positioned across the wall.

Q: Does the decoder support KVM for a control room position?

Yes. The QG-FBSR52K supports KVM over IP at the operator position for distributed KVM and command center KVM configurations.

The display-side endpoint of an AV over IP architecture. QG-FBSR52K receives network streams and drives any display, video wall or multi-screen group — with any-source-any-screen switching and KVM over IP at the operator position.

What the Decoder Does in the System

In an AV over IP architecture the decoder is the display-side endpoint. It joins the network, receives one or more streams from encoders, decodes them and drives the connected display. Because selection happens in software, operators can switch any source to any screen instantly — and a group of decoders can be coordinated to form a video wall.

QG-FBSR52K FAQ

Can multiple decoders form a single video wall?

Yes. Multiple QG-FBSR52K AV over IP decoders can be coordinated into one logical video wall over IP, with source windows positioned across the wall. This is the standard approach for video wall control room and operations center AV distribution deployments.

Is there a limit to how many sources one decoder can switch between?

Because routing is managed in software on the network rather than by a fixed-size switching chassis, a decoder can switch between any available AV over IP encoder on the network. The practical limit is set by network design and stream count, not by a hardware switch matrix size.

Does the decoder support KVM for a control room position?

Yes. The QG-FBSR52K supports KVM over IP at the operator position, enabling distributed KVM and command center KVM configurations where an operator views distributed video and controls remote machines from one desk.

Is the QG-FBSR52K available for OEM / private label?

Yes. It is available as AV over IP ODM hardware under your brand with custom firmware, custom enclosure and protocol integration. See the OEM / ODM programme.

SR52K: Dual-Channel AV-over-IP Decoder with 4K HDMI over IP and H.264/H.265

The SR52K is a dual-channel AV-over-IP decoder and 4K HDMI over IP decoder for display-side delivery. As an H.264 H.265 video decoder it converts network streams back to HDMI, supporting video wall layouts, picture-in-picture, quad-view and KVM-over-IP operator consoles.

Pair SR52K decoders with ST52K encoders on a standard 1GbE switch fabric to build video over IP distribution of any size — add decoders as your screen count grows.

What can the SR52K decoder output?

The decoder renders subscribed AV-over-IP streams to local displays with support for video wall cells, picture-in-picture and quad-view layouts, and provides KVM-over-IP control for operator workstations in control rooms and command centers.
