Live Contribution In UHD/4K
Is A Reality
Recent contribution encoding innovations make
live UHD/4K video a reality for broadcasters,
says Ronan Poullaouec, CTO...

C

onsumers all around the world
have
been
enthusiastically
purchasing 4K TV sets, demonstrating
they are ready for more Ultra HD
(UHD)/4K video content.
From a broadcaster's perspective,
however, remote production of
live UHD/4K content is not easy.
Broadcasters
require
advanced
encoding technologies in order to
transport live UHD/4K content from
remote locations to the studio without
incurring exploding costs. To ease
the problem, lately, there have been
a number of key innovations on the
encoding front that facilitate this
process.
The HEVC video compression
standard has emerged as a superior
standard to H.264/MPEG-4 AVC from
an efficiency standpoint, allowing
broadcasters to produce the same
level of video quality at half the bit

rate, or improved video quality at
the same bit rate. While HEVC offers
a boost in compression efficiency,
broadcasters still need to ensure
that video quality is maintained once
content hits contribution networks.
Utilising an encoder integrated
with powerful contribution network
protocols, such as the H-ARQ
(Hybrid - Automatic Repeat Request)
mechanism,
broadcasters
can
seamlessly deliver live UHD/4K video
content over managed or unmanaged
contribution links (public networks
/ cloud), despite poor network
conditions. The H-ARQ method relies
on a mix of Forward Error Correction
(FEC) and packet retransmission
coding.
Another feature that broadcasters
interested in delivering live UHD/4K
video content definitely want to look
for, is network bonding technology.

AVIWEST facilitate UHD/4K newsgathering

By choosing an encoder capable
of detecting and bonding together
multiple IP-based networks - for
example 3G, 4G, Wi-Fi, Ethernet, and
satellite - broadcasters can ensure
QoS requirements. Video content is
compressed based on the real-time
characteristics of bonded networks,
their bit rates, and delays, bringing the
ultimate live UHD/4K experience to
end viewers.
HEVC, H-ARQ, and network bonding
technologies are decisive for live
UHD/4K video contribution. Ultimately,
these advanced technologies will pave
the way toward enabling UHD/4K
newsgathering, affordably, from any

remote corner of the world.
At IBC 2015 on stand 2.A29, AVIWEST
is demonstrating how broadcasters
can utilise these technologies via
our new DMNG HE4000 HEVC 4K
contribution video encoder, designed
to allow flawless live UHD/4K delivery
with low operating costs.
Compared with other solutions on
the market, the HE4000 features a
unique IP network bonding technology
called
AVIWEST
SafeStreams®
that assures the delivery of live
transmissions even in the midst
of unpredictable cellular network
conditions, transforming live UHD/4K
delivery.
