An Overview

Content Service Innovations

Sky is HD market leader


From 6 to 65 HD channels in three years

Why Ultra HD?

• internal activities started at the end of 2011• IBC (Sept 2012): first public announcement• test shooting at Bundesliga match on 1 Dec 2012• further test productions in Feb 2013• Sky plans to be the first to introduce Ultra HD services

Brian Sullivan, CEO of Sky Deutschland:„Ultra HD is extremely exciting for us and even more exciting for our customers.”“Innovation is one of the cornerstones of Sky.”“The introduction of HD in Germany was too late …

… we will not repeat the same mistake again.””Sky will continue to invest in 3D."“Ultra HD still seems to be a long way off, but our first experience is captivating.”


Success of HD is motivation for Ultra HD

Preliminary findings from first test

• production was far from being a real live Ultra HD test• no Ultra HD broadcast cameras available• no OB van equipped for Ultra HD yet• entire production/distribution chain needs to be upgraded first

• test was targeted at potential “look” of Ultra HD sports production (panning, zooming, etc.)

• change from SD to HD required a whole new production grammar• will Ultra HD require a “best seat in the house” approach?

• the step to Ultra HD appears to be less radical (preliminary findings)• focusing challenging, blur a lot more noticeable in Ultra HD• panning/zooming seem manageable• entire production had a certain “film look”

From HDTV to Ultra HD


Where are we today?

Content Acquisition

Production Distribution Receiver Displays

4K

4K professional cameras available, but not

suitable for broadcast productions

limited availability of 4K content from studios

vast amount of data(4x up to 16x HD)will require major upgrade of entire production chain

(servers, editing suites, on-screen graphics,

network, OB vans, etc.)

possible with H.26425-50 Mb/s per feed(≈2 feed/transponder)

will benefit from HEVC(≈ 50% more efficient)

final draft Jan 2013

hardware update of HDMI interface required

to support 4K output

next gen receiver with HEVC support in 2015

4K displays/projectors available to consumer,

but still expensive(risk of security lack due

to HDCP hack)

8K very few 8K camera prototypes

possible with H.264180-300 Mb/s per feed(<0.5 feed/transponder)

probably not suitable for sat transmission even

with HEVC

most likely not before 2020 (IP receiver?)

8K displays/projectors prototypes only

necessary sizes of up to 200 inches not yet fabricable (up to 85

inches so far)

Ultra HD related industry efforts

• various standards bodies and consortia working on Ultra HD• defining an Ultra HD broadcast profile involves several parameters

• spatial resolution• temporal resolution (frame rate)• colorimetry• bit depth• dynamic range• aspect ratio

• new video codec:(HEVC)

• new chipsets will be required for encoders and receivers• industry is also working on new interfaces (e.g. HDMI 1.5)


A lot of standardization still required

source: SES Astra

Ultra HD related industry efforts

EBU WG “Beyond HD” / PTS 2013• first subjective tests HD vs. Ultra HD (uncompressed)• Ultra HD wins, but difference is marginal

SMPTE Study Group on UHDTV Ecosystem• drafting report for publication in Mar 2013• overlaps with activities of German TV Platform

Study Group UHDTV of the DVB Commercial Module• online survey regarding Ultra HD in Feb 2013• DVB UHD-1 Broadcast Profile Workshop in May 2013

HDMI 2.0• specification delayed until mid 2013

HEVC / H.265• publication by the ITU on 25 Jan 2013• currently three different profiles (max. 10 bit, 4:2:0)


What happened since CES 2013

Sky Ultra HD

• preparation of further subjective tests in collaboration with EBU• ad-hoc studies conducted by Sky show promising results

• good up-conversion of native HD material on Ultra HD displays• HD viewing benefits from (down-converted) native Ultra HD

• all preliminary results to be confirmed by more scientific tests• Sky will continue Ultra HD live production tests in 2013 (and beyond)• Sky chairs German TV Platform working group on Ultra HD

• next generation Sky receiver will be “Ultra HD ready”• migration of entire infrastructure to Ultra HD in early planning phase

• regular Ultra HD will launch as soon as possible (no concrete launch roadmap to date)
