BT 4K TV
At last week’s very excellent UKNOF35 meeting in Glasgow BT Chief Network Architect Neil Mcrae gave a talk about the BT 4K TV project. 4k has been creeping up on us for a while now and TVs that notionally support it have been in the shops for at least a couple of years (mortgage application pending).
For me the interesting thing about Neil’s talk was the fact that a 4k stream needs 30Mbps bandwidth. Not all households will therefore be able to receive the service and this I understand. It’s a competitive world and in a marketplace here BT is trying to up its content game then an early launch of 4k services makes a lot of sense. They have stolen a march.
This issue from the Davies perspective though is the fact that we have four kids. Ok they don’t all live at home now but when they did the one noticeable thing about our house was that we had six people all watching streaming media from different rooms in the house.
Extrapolate this to 6 x 4k streams and all of a sudden we would need 180Mbps downstream. Actually we have 200Mbps but I doubt a high proportion of the populace has the same connectivity.
BT 4k TV is clearly a driver for more bandwidth to the home (actually any 4K TV). I’m also shooting a lot of 4k video with my Samsung Galaxy S7 Edge and uploading this to Google Drive. On occasion I’m also subsequently downloading it to my Macbook for turning into a produced video/vlog and then uploading it again to YouTube. The file size in this case can be huge – several gigs and so my upload speed is also very important to me.
So where is this taking me? We (a majority of us – not all) have come a long way since the first ADSL rollout. We clearly still have a way to go. My prediction is that by 2020 we should be looking for 1Gbps to the home. Why not? By then 8k will be out (whether we will be able to tell the difference or not – the marketing hype will persuade us that we can). If I still had four kids in the house then I imagine the six streams will use up most of that Gigabit.
The question is who is going to deliver?

PS Excellent UKNOF 35 btw – well done Keith, Denesh, Chris and Mike and the growing number of peeps needed to make it happen.
PPS I’ve looked at various Pay TV services and there ain’t much on I want to watch so I’m not a customer!
