ST 2110 for people who love SDI
8 min readHyperlax Engineering
There is a particular comfort in an SDI cable: one signal, one path, a satisfying click. ST 2110 replaces that certainty with a network — and networks feel like weather. This guide is how we teach SDI natives to trust the fabric.
Think flows, not cables
In 2110, video, audio and ancillary data travel as separate essence flows. The mental shift: a "cable" becomes a subscription. A destination asks the fabric for a flow, and NMOS handles the introduction.
Redundancy stops being a second cable and becomes ST 2022-7: two identical packet streams over independent paths, merged seamlessly at the receiver. When one path dies, nobody notices — which is the point.
The three rules we drill
One: PTP is the show. If timing is wrong, everything is wrong. Guard your grandmasters. Two: monitor the fabric, not just the pictures — packet loss precedes visible errors. Three: label flows like you labelled cables. Discipline survives the transition even when the copper does not.
