Marathon by German production
company Tividoo for regional
public broadcaster SWR's online
coverage. The race was covered
by a combination of emerging
technologies. Tividoo filmed the
event from a car alongside the
runners, and then held post-race
interviews with the runners in the
main square. The car was fitted
with a Viprinet Multichannel 510
Router that can bond up to four
4G networks as well as a Ka-Band
satellite connection. This created a
WLAN around the car. While moving
and filming the runners 4G uplink
connectivity was used, augmented
with Ka-Band when stationary at the
end of the race. An iPhone 5 with
the LiveU LU-Smart app and an
LTE SIM was attached to a steady
rig and a stabilised car mount and
used for the actual video capture.
Financial pressure is a key reason
for the switch to mobile phone
technology. As Ronen Artman, VP of
Marketing, LiveU observes: "Using
satellite for uplinking has been - and
still is - considered expensive and
has tended to be the preserve of
Tier 1 broadcasters."
Even then, while viewed as ideal,
satellite uplink still has its limitations,
as Artman says: "This is fine for
major, planned events but not so
great for breaking news."
The expectation that mobile
networks may sometimes be ill
suited in their naked form is also
borne out in real life scenarios.
Martin Weber, Channel Sales
Director of miniCASTER, explains:
"I can get 1.5Mbits upstream in my
office but in the centre of Munich

if you will get any bandwidth
suitable for streaming. If you only
get 80K per SIM you still get

even when bonding 12x SIMs." He
concludes with a warning about
the unreliability of even seemingly
strong signals: "I have seen
bonding-systems do 2Mbit and then
drop to 700kbits and stay there for
two minutes."
For this reason, miniCASTER
is wedded to ka-band 10Mb
transmission. For others, however,

(LTE) is an alternative to SNG but

secondary bandwidth.
Jon Landman Teradek's VP of
Sales outlines their approach: "The
typical bonded uplink is as stable
as the cellular towers in the area. To
provide redundancy in challenging
environments such as professional
s p o r t s s t a d i u m s , Te r a d e k
bonding units can aggregate
up to six network connections
simultaneously. In addition to 3G/4G
LTE modems, broadcasters can
also bond Ethernet, BGAN, and
WiFi connections for additional
bandwidth, especially when cellular
towers are out of service."
As well as employing Teradek's
clever workaround approach (which
is also utilised by Dejero's LIVE+),
LiveU focuses on maximising the
quality of experience by leveraging
available network resources.
According to Artman: "The uplink
