Default Blue Planet II Comes To iPlayer In 4K HDR

http://www.bbc.co.uk/news/technology-42225220

"The BBC's Blue Planet II programme is to become its first TV series to
be made available in 4K resolution and high dynamic range (HDR) colour
via its iPlayer catch-up service.

All seven episodes of the marine-themed show are being made available to
UK-based owners of select TVs.

Until now, the BBC had only released programmes in this format via
ultra-high definition (UHD) Blu-ray discs."

But what they don't say is whether the dynamic compression management
system employed on iPlayer's servers will allow end-users to download
the programmes without them being ruined by over compression at download
time.

It doesn't say it'll be made available for web browsers
or g e t i p l a y e r, only for TVs, though I expect it's just a magic
"uhd" quality keyword that needs to be discovered, the SES and Astra UHD
H.265 test streams on 28.2E aren't bad.

I do hope it does come as it will be the first proper 4K programme that
I will watch.

What sort of download speed is this going to need?

Judging from the Astra/SES UHD streams (which are 4K but AFAIK not HDR)
they seem to peak about 11Mbps according to VLC, so a bit higher than
that I presume.

The web site says that it will be available on iPlayer immediately after
the final episode on Sunday.

What basically is the difference between iPlayer and Netflix, whereby
Netflix needs an internet connection speed of 25 megabits per second or
higher for UHD?

Pardon my ignorance, but would the 10k stream be for Flash or HTML5.....the
Beeb seems to be hanging on to Flash.

Which is seven weeks too late, since most people will have already
watched it in HD, too late for UHD.

Sky Q makes UHD downloads available as soon as the HD episode starts
airing. Although a pitiful selection at present, two or three
programmes a week.

The first series of Babylon Berlin was UHD (converted) but not the
second series which continued straight on.

No BBC UHD material on Sky Q.

IIUC They now prefer and provide HTML5 and other alternatives, but continue
Flash for people using old software that doesn't request the newer methods.
Flash has been 'deprecated' (if that's the right term) for some time now, I
think.

So the answer may be in your own hands.
