But to be fair, there is a standard that could have been used for digital video, SDI/HD-SDI, but the transceivers were expensive and it doesn't support any form of bi-directional handshake. There was already prosumer kit, mostly in the US, which had SD-SDI connections as an alternative to component. It didn't get popular in Europe mostly because of SCART.
I was once talking with someone who was very much involved in the process of standardising TV connectivity, a senior engineer at Gennum, and he said it wouldn't have been practical and SDI couldn't have been competitive with HDMI.
Oh, for sure. That and ADAT are great examples of tech that worked and worked well - and maybe even instrumental in HDMI's later adoption of optical tech in their cables.

Personally, I would have loved the idea of some kind of SDI with return path signalling, like a test probe connector: https://w140.com/tekwiki/images/thumb/8/86/Tek_Interface_Evo...
