Thanks for the comprehensive reply - I didn't realise that the latest video and gaming ran so fast and had such large files that need to be updated regularly!
For reference, when I was working on it, BT Sport contribution, (ie from Outside Broadcast site to Stratford studios), for 4K ran at around 100 and 140Mbps - that is the high quality feed before it was processed for distribution to customers at a lower bit rate.
