BBC Democracy Live unfortunately died a death, a great shame because it would be more valuable than ever now. It was fairly groundbreaking in its day!
Considering that BBC Parliament on Freeview is at a dire 544x576 resolution, it hasn't stopped the channel gaining a new audience to watch the Brexit debates.
As I've said before, 'content is king'.
I've not investigated, is there a live iplayer stream available?
BBC Parliament is available on iPlayer. There isn't a dedicated HoC stream though.
Parliament itself offers live HoC
A media company called Digital Tree also legitimately streams both on Twitch under license, they recently moved their 'ukparliament' channel to (unironically I think!) https://www.twitch.tv/democracylive
They're fairly basic in presentation with the usual lower thirds, debate info, speaker info etc - however the live chat can occasionally make for a very interesting shared experience. 'democracylive' is the 'curated' channel, https://www.twitch.tv/ukcommons
are the dedicated ones.
