it cellular, Wi-Fi or satellite, then
you can’t deliver your live content.
“The other thing is getting
access to a large enough ‘pipe’ to
be able to do bidirectional data
transfers so that video and data
can be worked on and packaged
quickly and more efficiently.”
Dejero is also a strong advocate
of the HEVC/H.265 video com-
pression standard, which Santillan
describes as “a major step forward”
as the demand for higher resolu-
tion and better picture quality
increases.
HEVC/H.265 is now a standard
feature in the EnGo mobile trans-
mitter, which combines Dejero’s
proprietary auto-transport and
adaptive bitrate encoding technol-
ogy to optimise picture quality
when there is limited bandwidth.
A new offering from Dejero
is PathWay, an HEVC/H.265
rack-mount encoder/transmit-
ter, which supports 1080p at
25/30/60fps. The increased frame
rates, according to Santillan, deliv-
ers “smooth, high-motion video”
preferred by broadcasters for
sports and eSports coverage. “On
the receiving side, we introduced
our four-output WayPoint re-
ceiver, which provides the flex-
ibility of receiving HEVC/H.265
and AVC/H.264 streams. This is
helpful as broadcasters transition
to HEVC/H.265,” he adds.
In line with Dejero’s vision to
provide reliable connectivity any-
Dejero is working to enhance how it helps customers send live feeds via IP
throughout the entire production chain. For instance, the company’s IP network
blending technology was deployed at the Winter Games Winter Games in
Pyeonchang, South Korea earlier this year.
where to help broadcasters deliver
their content from any location,
at anytime, the company has also
introduced CellSat, a blending cel-
lular and Intelsat Ku-band IP satel-
lite solution. Santillan illustrates:
“If a news crew is in a remote
location where cellular coverage
may be limited, or in a heavily
congested area where the available
bandwidth may be sporadic, the
Dejero CellSat solution that we
developed with Intelsat enables
mid-stream activation to blend
in with satellite with the available
connectivity. This provides enough
bandwidth to deliver high-quality
video, without losing the shot.”
Because the satellite connec-
tivity that is blended with cellular
is available on-demand, users do
not need to worry about making
prior bookings for satellite time.
Better cost management is offered,
as they are billed for their CellSat
connectivity by Dejero, instead of
having to manage bills from multi-
ple cellular and satellite providers.
In essence, Dejero believes that
IP workflows simply provide great-
er flexibility for content creators
involved in remote productions.
For instance, the Dejero GateWay
solution provides a big virtual pipe
between the production vehicle
and the Internet. This enables field
crews to transfer large data files
and digital assets back and forth
from the remote location to the
central broadcast facility. It also
gives reporters and producers ac-
cess to newsroom systems from a
breaking news scene — an option
that was just not possible before,
says Santillan, who also adds a
word of caution: “With 10G and
40G, and presumably 100G soon
to be generally available, the idea
of going full IP makes more sense,
given its inherent advantages of
flexibility and scalability.
“However, it is the type of
content that will really define the
workflow. SDI is still the most cost-
effective way if it’s just your ‘typical
HD production’ — it also comes
down to what your budget
