National Theatre to Present Live 4K Broadcast of 'War Horse'
Working in partnership with Sony, Creative Broadcast Solutions, NEP Visions and Links Broadcast
February 24, 2014
—National Theatre Live and Sony are teaming up to broadcast
the production of “War Horse” live in 4K.
On Feb. 27
2014, National Theatre Live will broadcast “War Horse” live from the New London Theatre to cinemas across the
world. The broadcast will be shown in Sony 4K at the Curzon Cinema in Chelsea,
the production will be projected using a Sony projector. The recording will
be available as a 4K DCP allowing many 4K enabled cinemas to also show encore
screenings at a later date.
Broadcast Solutions, technical producer for NT Live, with NEP Visions, NT
Live’s long-term OB partner will work with Sony, using Sony’s F55 Super
CineAlta cameras equipped with Fujinon
Cabrio lenses to capture the performance. NEP Visions will
provide the technical infrastructure and expertise to take the 4K content from
camera to satellite, as well as recording and broadcasting a simultaneous HD
The cameras will feed 4K content into Sony BPU4000 fiber adapters, which will generate 4K and HD signals simultaneously. The feeds will then be sent
to a 4K capable vision mixer to create a live mix from the six camera feeds,
adding graphics and subtitles for the HD version only. Pre-recorded supplementary program materials have been ingested
onto a Sony media server to play in. The live mix is
passed to the satellite service provider Links Broadcast. The mix feed is
recorded on a Sony MasterDeck, both for archive and the creation of a 4K DCP master
that will be sent to theaters around the world. NEP Visions also will record 4K
ISOs onto two additional Sony MasterDecks for later use. As well as the 4K presentation, NEP Visions will provide a simultaneous live HD
feed for distribution by Links Broadcast to more than 1,000 cinemas worldwide in line
with NT Live’s existing program of broadcasts.
Links Broadcast will
provide the satellite uplink and downlink facilities to enable the delivery of
the War Horse 4K signal from the New
London Theatre in to the Curzon Cinema in Chelsea. The Links Broadcast 4K
uplink will operate alongside Links’ HD uplink facility and will enable the
encoding of the incoming 4K content. Using four synchronous Adtec EN-100
encoders the incoming signal is combined in to a single transport stream via an
Adtec DTA3050 multiplexor for onward transmission via a 1.5m antenna on Links
Broadcast’s 4K uplink vehicle.
The 4K signal will be uplinked on to SES Astra’s
3B satellite using 36 Mhz of capacity in order to achieve the maximum possible
video data rate within the modulated 4K transport stream.
The incoming signal will
be downlinked at the Curzon cinema in Chelsea via a 1.8 M Links Broadcast
receive antenna, which will be fed in to Adtec RD70 receiver decoders and will
be delivered to Sony’s 4K cinema facility for the projection.
Decoded 4K pictures will be fed directly to Curzon Chelsea’s Sony projector.
