HEVC: Changing The Economics Of OTT

Thomson Video Networks discusses the OTT
revolution and the HEVC TV solution...

he exploding demand for overthe-top (OTT) video services
is both a blessing and a curse
for media enterprises that have
built their businesses around
conventional broadcast television.
While the traditional TV audience
is still huge and well-established,
viewership has been on the decline
for several years as more consumers
expect access to high-quality video
on the Internet-connected device
of their choice - ranging from
computers and laptops to smart TVs,
smartphones and tablets, and even
gaming consoles.
The OTT revolution is creating
compelling new opportunities for
broadcasters to maximise brand
awareness across multiple delivery
platforms, grow new audiences,
reduce churn in pay TV services, and
increase revenue streams through
more targeted advertising. However,
effectively monetising OTT services
is still highly uncertain in today's
complex media environment. For
traditional broadcasters, integrating
OTT into the mix is not a question of
"if," but "when," and how to do so
as profitably and in the most costeffective and bandwidth-efficient

manner possible.

Bandwidth Challenge

By nature, OTT services are
distributed in unicast, point-to-point
mode, meaning that bandwidth
requirements increase with the
number of users. OTT can be
especially expensive for large-scale
broadcasters that rely on content
distribution networks (CDNs) to
deliver their services since most
CDNs providers base their fees on
user volume. Therefore, the more
popular the service, the more
expensive and less profitable it
is to operate unless bandwidth is
somehow maximised.
As the number of OTT devices
grows, so does the complexity
of delivering a consistent and
high-quality experience across
heterogeneous devices bearing
different operating systems, screen
sizes, and encoding formats. To
satisfy the full range of consumer
demand, OTT services must be
compatible with each vendor's
specific technology environment
including adaptive bit rate (ABR)
technologies such as HTTP Live
Streaming (HLS) or Smooth

Thomson Video Networks' Multi-Screen and HEVC TV Solution

Thomson Video
Networks' ViBE
VS7000 Multi-Screen
Video System

Streaming for mobile phones
and tablets (including Apple
iOS, Android, and Windows
devices), as well as PC,
Mac, and Linux browsers.
A bright spot on the horizon
is the Dynamic Adaptive
Streaming over HTTP
standard (MPEG-DASH),
which provides a
common standard
for high-quality
Internet streaming.
As more device
manufacturers come
on board with MPEG-DASH, OTT
delivery will be greatly simplified.
But in the meantime, operators
must allocate sufficient bandwidth
for each ABR variation.

HEVC - OTT Future

The good news for OTT providers is
the emerging High Efficiency Video
Compression (HEVC) standard, now
considered the worthy successor
to the current state-of-the-art
encoding format, H.264/MPEG-4
AVC. In early testing, HEVC has
demonstrated a bit-rate reduction
of up to 50% over H.264 - implying
that OTT operators can send the
same number of streams with half
the bandwidth. In this scenario, OTT
not only becomes a more profitable
venture but the picture quality is able
to keep pace with consumers' everevolving expectations as ultra highdefinition (UHD) television delivery
begins to emerge.

Emerging Standards

Advanced encoding technologies
will be a critical success factor as
media enterprises begin to realise
the promise of HEVC for nextgeneration OTT delivery. Already,
advanced encoding technologies
will be a key enabler - and the
emergence of 4K HEVC decoder
chipsets is driving some encoding
manufacturers to add HEVC
functionality to their solutions. One of
the first worldwide implementations
of HEVC is Thomson Video Networks'
ViBE VS7000 multi-screen video
encoding/transcoding system,
and the company's A/V Codec
analyser is one of the first test and
measurement tools to offer in-depth
analysis of HEVC-encoded video.
In addition to supporting
today's H.264 delivery via all
major ABR streaming formats, the
ideal encoding platform can be
extended via a simple software
upgrade to accommodate HEVC,
MPEG-DASH, and other emerging
standards into the future. With the
right encoding solution, operators
have two approaches for maximising
bandwidth: a service that uses less
bandwidth to maintain current
video quality levels, or delivering
significantly higher quality without
an increase in bit rates. And, since
viewers hold the quality of their OTT
content to the same standard as
home TV output, the best encoding
solutions should deliver high-quality
output as well as bandwidth savings.
With HEVC, the future looks bright
for HD and UHD content delivery
on any type of device and network
- especially in combination with
other emerging standards such as
MPEG-DASH, eMBMS, and LTE. In
the near term, these exciting new
technologies can deliver bandwidth
savings that translate directly into
reduced operating expenses, while
smoothing the way for video delivery
in today's most advanced multiplatform services.
