I think the better question is why SDI video connections aren't available on any consumer devices.
While HDMI is nice for consumers because it carries audio/data, SDI cables are cheap (just a single coax cable!) and easy to route (T-splitters are a thing!).
SDI does not support HDCP, however.
- babypuncher 5y agoI think cost might be the main factor there. SDI is serial instead of parallel like all other consumer digital video cables. Hardware to serialize and deserialize bits this fast on a single conductor is expensive. HDMI 1.0 had a max transmission rate of 4.95 Gbit/s in 2002. Today, HDMI 2.1 goes up to 48 Gbit/s.
