OTT Trends - Part II
In the second part of InBroadcast's look at OTT, Contributing Editor
Adrian Pennington explores the latest technologies in HEVC encoding
and the potential of blockchain in media...

development in the live streaming
ecosystem and advancements in
internet connection speeds, we're
at a point where live video quality is
acceptable for the average viewer.

mostly spotty and low quality 480p,
now it's common to see 720p Facebook

low latency video backhaul and
transmission applications, expands the
Makito X H.264 capabilities with dualchannel HEVC encoding and increases
the quality of IP video streaming.
The Makito X HEVC has all the core
features of the Makito X, including
dual 3G-SDI inputs, support for
up to 1080p60 HD video,
multi bit rate streaming,
KLV metadata support and
networking capabilities like
traffic shaping and optimised
bandwidth performance. The
new encoder also comes with
Haivision's Secure Reliable
Transport (SRT) technology
for video delivery over public internet
and firewall traversal. The unit is
compatible with HEVC broadcast
decoders, set-top boxes, soft players,
Haivision HEVC/H.264 transcoders,
and the Haivision Media Gateway.
Available as a firmware upgrade
for any Makito X encoder, Network
Adaptive Encoding dynamically adjusts
the video bitrate when available
bandwidth fluctuates. Leveraging
Haivision's SRT low latency streaming
protocol, changes in the network
capacity are detected and relayed to
the encoding engine. If the bandwidth
drops below levels that can support
the preset output bandwidth, the
bitrate is reduced to levels that will
assure the best video is transmitted.
If the SRT protocol detects that
bandwidth capacity is restored, the
encoding engine will increase the video
bitrate to maximise video quality.
Peter Maag, Chief Marketing Officer
of Haivision explains, "With Network
Adaptive Encoding, if your bandwidth

chokes, your stream keeps going. It
helps you plan for the best because we
have already prepared for the worst."
It's worth noting that over 70
companies have announced support
for SRT since Haivision made it open
source. Members who view SRT as an
alternative to RTMP, include Kaltura,
Harmonic, Limelight and Brightcove
along with Microsoft Studios.
"The adoption of SRT and the
excitement in the industry about the
technology and the alliance has been
overwhelming," says Sylvio Jelovcich,
VP of Global Alliances at Haivision. "As
they say, there is power in numbers.
The SRT Alliance has grown more than
80% since IBC2017 and we are well on
our way to making SRT a standard."
Beamr Imaging's Beamr 5 HEVC
software encoder is claimed to achieve
real-time 4K 10-bit HDR support
that is compatible with Dolby Vision,
HDR10 and HLG. The software has
been demonstrated running on the
high density 2U SYMKLOUD MS2910
platform.

Benefits: Beamr 5 HEVC software encoder

"Beamr's ground breaking HEVC
encoder running on SYMKLOUD is an
ideal enabler for video services looking
to move their channels over the top to
meet the consumer demand for video
anytime, anywhere," says Beamr VP,
Marketing, Mark Donnigan. "Industry
leaders looking for cost effective
HEVC solutions will find the Beamr
5 + Kontron MS2910 combination
extremely appealing and an enabler to
new distribution business models and
system architectures such as just in
time encoding."
VITEC's MGW Ace Encoder firmware
v2.0 is the next generation of the
company's hardware-based HEVC
encoder. Powered by the new HEVC
GEN2 codec, the MGW Ace Encoder
provides video quality of up to
4:2:2 10-bits HEVC encoding and is
claimed to surpass the second-best
competitor by 20% to meet the quality
requirements of demanding broadcast
applications.
