EVERY SIGNAL.
RIGHT ON TIME.

Broadcast IP engineering for the moments that cannot be repeated. From the camera head to the control room, we build the paths that keep live production moving.

01 / WHAT WE DO

THE SIGNAL IS
THE MISSION.

Purpose-built infrastructure for broadcast facilities, live events and mobile production. Designed around the formats, distances and failure scenarios that matter to your operation.

01 / ROUTE

IP VIDEO FABRICS

Non-blocking ST 2110 leaf-spine networks, NMOS control and resilient signal paths for production at scale.

PRECISION CLOCKING

PTPv2 grandmasters, boundary clocks and timing design that keeps distributed sources in step.

03 / CONTRIBUTE

REMOTE & MOBILE

SRT and NDI contribution, event connectivity and integrated systems for mobile OB trucks.

KNOW YOUR
HEADROOM.

Estimate video payload and redundant trunk capacity before you select a fabric. Use the output as a starting point for a detailed network design.

SIGNAL INPUTCALC / 01

2022-7 duplicates ST 2110 flows over independent networks. It is not applied to NDI or SRT in this estimate.

ESTIMATED OUTPUT● CALCULATED
LOAD PER PATH—Gbps / INCLUDES 20% PLANNING MARGIN
COMBINED A + B—Gbps
25 GbE UTILIZATION—per path
100 GbE UTILIZATION—per path
SRT LATENCY—ms starting target

Planning model: 10-bit 4:2:2 active video for uncompressed, 10:1 JPEG-XS, illustrative Full NDI and HEVC rates, plus 20% transport and capacity margin. SRT latency begins at 4 × RTT, configured at both ends; test and increase for loss and jitter. Audio, ancillary data, multicast replication, packetization, link speed and non-video traffic need separate engineering. Actual codecs and devices vary.

03 / SYSTEM ARCHITECTURE

TWO PATHS.
ONE PICTURE.

A resilient fabric is a system, not just a switch specification. Timing, control and media paths need to be designed and tested together.

CHOOSE THE
RIGHT PATH.

Latency is a system property. These are directional planning ranges, not guarantees; codec settings, buffering and network conditions determine the measured result.

BEYOND THE
CONTROL ROOM.

Practical observations from the wider world of live production, from open-water contribution to the virtual green room.

01 / FIELD NOTE

Semiconductor allocation & live graphics

When silicon is scarce, the broadcast chain feels it long before a camera reaches the floor.

READ THE NOTE ↗02 / FIELD NOTE

Field lighting & ENG contribution

Build an outdoor camera position that can survive a change in weather and still produce a dependable signal.

Esports observer feeds & replay

A competitive player display and a broadcast program feed have different jobs. Engineer the split before match day.

READ THE NOTE ↗04 / FIELD NOTE

Marine cameras & telemetry

A moving vessel is a difficult camera platform and an even more difficult place to guarantee an uplink.

READ THE NOTE ↗05 / FIELD NOTE

Venue atmosphere & particulate telemetry

Haze can make a show look spectacular. It also changes the environment around cameras and projection systems.

READ THE NOTE ↗06 / FIELD NOTE

Virtual green rooms & remote guests

The best remote contribution path makes it easy for a guest to listen, respond and stay in sync with the room.
