EDGE significantly reduces the need for on-site
production equipment and teams. "
For example, a broadcast
solution
provider
deployed Monarch EDGE S1 encoders to deliver live
streams in an international football championship
qualifier. The setup required minimal infrastructure
and removed the need for satellite trucks and large
teams. The integration into the video workflow
involved remote monitoring, stream analysis, and
recording for post-production, ensuring a smooth,
end-to-end solution that fit into both live streaming
and

needs. Andrews
adds,
" Monarch EDGE's affordability and adaptability
open new opportunities for broadcasters to cover
events without the high overhead traditionally
associated with live sports production. "
As anyone who has ever tried implementing a
practical solution for remote production will tell
you, sending precision time protocol (PTP) over the
internet to sync sources is extremely difficult.
The view at SipRadius is that PTP is too accurate,
even " unnecessarily accurate for our needs, " says
Sergio Ammirata, founder and Chief Scientist.
" Millisecond precision is good enough when we
are synchronising a new picture every sixtieth of
a second: we do not need to count microseconds.
Especially with compressed codecs that transmit
and process one video frame at a time.
" We propose a simple device, the MRTC
(Master Router/Real Time Clock). This acts as
the connect point
for transmission of signals
over non-deterministic IP circuits (like the public
internet), but also includes a receiver for a freelyavailable
time source, like a cellular signal or
GNSS with 0.1ms/0.001ms precision respectively.
Every node in a complex remote production has
synchronisation to millisecond accuracy, which is
good enough for broadcast purposes.
" This is a major
rethink for
the
traditional
broadcast engineer, expecting a single master time
source. The MRTC at each site is its own PTP grand
master, with GNSS or cellular providing local time.
MRTCs connect each site using a proven, highstability
protocol like MPEG-TS over RIST, ensuring
secure, very high quality transmission of audio,
video and metadata. "

which can be used to create rich remote networks,
