Modern video conference solutions allow individuals to join, rather than requiring people to gather in rooms, and as that does indeed change the number of feeds involved they generally offer the ability to hide some or all feeds.
Usually they'll be configured to share a document in a main window and show video of the speaker alongside it. If it's a presentation that may be all you get.
For Parliament a change to put the current speaking MP (can't call them the Speaker, as that's Sir Lindsay) in the main window would be sensible.
In either situation you could show thumbnail sized video for each other attendee but that tends to only work for meetings with 5-6 people in.
