This allows ROKS to offer complete
MITRIS-CS distribution systems that
are based as much as 70% on their own
hardware.
With customers all over the world
from Algeria to Kenya to Spain, ROKS-
TV has become a globally powerful
company with their one-of-a-kind TV
distribution solutions.
MITRIS-CS is a very interesting al-
ternative to standard TV distribution
technology; it makes it possible to sup-
ply TV services inexpensively to people
outside of larger city areas.
Because the MITRIS-CS infrastruc-
ture is based in large part on existing
technology and makes use of standard
satellite reception equipment, the costs
for end-users would also be quite low.
Thanks to this technology, ROKS has
become the reference company and is
the first contact when it comes to the
setup of a MITRIS based network.
development and manufacture of mi-
crowave products for various applica-
tions but primarily it‘s the implementa-
tion of the entire MITRIS infrastructure
from broadcasting via radio relay up to
the headend.
It must be emphasized that the sys-
tem includes the word “information”.
This means that the MITRIS system
was not just meant as a system to
transmit TV broadcasting but also as a
data transmission system.
In the beginning, it was used for
analog broadcasts with some data
transmissions in parallel. With the
introduction of digital tv the tv sig-
nals and data signals merged and the
amount of data signals increased.
Eventually we will see the TV broadcast
part of the signal disappear and move
over to IPTV, thus making the MITRIS
system to a data-only environment for
the transfer of high data rates.
ROKS’ product palette is quite exten-
sive: LNBs, antennas, multiplexers, en-
3. ROKS developed their own
antennas to handle frequencies of
11-12GHz. Here you see antennas
used for repeaters.
4. What if you need to cover bigger
regions? No problem, just use
repeaters!
5. Another example of an
implementation. The head station
receives different transponders
over satellite and uses a combiner/
multiplexer to create the provider’s
bouquet. Channels can be
encrypted. The resulting stream is
then up-modulated and transmitted
through an omni-directional
antenna to subscribers in the
11.7-12.2 GHz band, while a second
directional antenna transmits the
stream in the 10.7-11.5 GHz band
to a relay antenna. Here, the signal
is up-converted again to 11.7-12.5
GHz and transmitted through the
antenna to the subscribers.
Notice the relatively low power
used.
