Boosting Newsgathering

means the production workflows and
its overall efficiency needs to be sped
up and streamlined. For that to happen
in any kind of consequential manner,
these reporters need access to reliable
and secure broadband connectivity
while on location.
A number of solutions that
solve connectivity and bandwidth
challenges are now available to such
teams, helping field personnel to get
content back to base securely and
efficiently. The Dejero Gateway invehicle mobile connectivity solution
for example allows crews working
on location to send and receive large
files, access their newsroom or media
asset management systems as well
as tapping into cloud services for
collaboration.
Blended IP Networking
Reporters can now acquire fast,
secure and reliable access to the public
internet and private networks, using
high-bandwidth blended IP network
technology on location enabling them
to access system, search and download
archived footage, edit their stories

disconnected and placed in a
backpack, or mounted directly on
a camera, to give crews maximum
mobility when on the scene of breaking
news and live events.
Core Update
Lastly, updates to the Dejero Core
software, that streamlines clip and
asset management workflows, mean
that the management of clips and
media assets by crews on the ground
and in-house can be more efficient
than ever before. The updates include
additional clip workflow support and
simplification; upcapped file transfer
rates; and a new 'transfer while
recording' operating mode.
The new 'transfer while recording'
operating mode, combined with faster
transfer rates, means that a clip can
start auto transferring from the field
to the server at the broadcast facility
while still recording. After recording
a clip, the transfer can be completed
within seconds of the recording
finishing, even if the clips are long.
This again means more time saved
for the teams and their respective
broadcasters.
All of these recent technology
advancements are putting the power
back into the hands of the field teams,
allowing them to handle their assets
more efficiently and to work more
closely with their in-house teams than
ever before.
