For single contributions it is as you say just PCs running TV the software, either one with an SDI output or one with a convertor that makes it SDI* You can't really go about sending special software to contributors, you just use what they have, whether that's Skype or Facetime or WhatsApp. Reporters will have special software like Luci Live
I'm pretty sure that in a lot of cases where there's real time interaction, for example Have I Got News For You the recording is taking place via a Zoom chat or similar, but what you're seeing is recorded locally. The quality isn't studio quality but it's much better than streaming Internet quality.
*TV companies never use HDMI except for either feeding a domestic monitor or where they are using a domestic device like a STB or DVD, they are converted to SDI
I’ve seen some setups (often one man band kits that are now deployed as home studios) where talent US and abroad connect the HDMI out directly to the laptop or CNG.
Yes - HDMI can be used for connecting very cheap field cameras that don't have HD-SDI output to LiveU/WMT/PC capture devices etc. - but it's not a broadcast interconnect standard used in control rooms or MCRs. Sky did this a while back for their low cost Election count coverage kits I think. Most broadcasters wouldn't be using field cameras without SDI outputs (as very few cameras that meet EBU Tier approval are HDMI-only - an exception being the Panasonic GH5s) - but in emergencies or for very low cost live kits they may.
Or just racks of PCs being plugged HDMI into the desk (with maybe cropping to hide controls etc) running zoom, teams, skype etc?
For Skype most broadcasters will use a SkypeTX box which has SDI outputs, though FaceTime requires an Apple device and most people doing FaceTime in studios will use a MacMini with an AJA Region of Interest HDMI->HD-SDI scan converter. Zoom used live will need a PC with an HDMI output fed through a scan converter too - unless you have a relatively rare PC with an SDI GPU output.
No mainstream studio vision mixer (switcher) in use by most broadcasters has HDMI connectivity.
Also is Luci Live just for radio or tv?
I've only come across Luci Live as an audio solution - but there are MVP and LiveU iOS solutions for video - which are in use.

With lots of shows featuring many Internet fed video contributions. Anything special being done for this? Or just racks of PCs being plugged HDMI into the desk (with maybe cropping to hide controls etc) running zoom, teams, skype etc? Or any special broadcaster software or devices being deployed? I.e do they give people special software before their appearances?
Just interested.
