UltraHD (4k/8k) distribution feasibility

post #1 of 5
Thread Starter 
What expectations can we have when the current infrastructures(broadcasting OTA/SAT/Internet) & storage capabilities are far away from handling such contents in a convenient way?
What time span should we take in account before a wide diffusion of this emerging standard will take place? A decade?

There's a test service in Europe run by Eutelsat. This is using current compression and modulation systems - and uses 4 x 1080/50p streams at 10Mbs each to broadcast 4 quarter-screen images that are merged into a single 3840x2160/50p signal.

So it takes up 4x the space of regular HD services, the best part of a full transponder. But it is on-air now.

H265 compression should improve this significantly.

A number of European and US broadcasters are trialling 4k production - and a number of 4k capable OB trucks are due to come on-stream soon. The UK's main Pay-TV provider has shot and screened 4k sport coverage.

BSkyB have done some trials and focus groups, and one of their main OB resource providers, Telegenic, are building a 4k truck. (Yep - Murdoch. Sky and the BBC were the major drivers for HD in the UK as well)

Not good, at least here in the US. We haven't fully gotten HD right yet, much less 4k.
