TM1 is a
transmodulator that allows existing DVB-S receiver to migrate to
DVB-S2
The TM1 Solution
The current
investment in VSAT networks is based on the DVB-S
transmission standard that is now facing obsolescence. The
new-generation DVB-S2 technology delivers significantly
enhanced network efficiency, with about a 30% savings
from improved satellite space segment utilization. Rather than
replacing the VSAT itself, a simple and cost-effective
upgrade can solve the DVB-S2 compliance requirement.
The new TM1 trans-modulation solution from Ayecka
enables a smooth, quick, economical migration path to improve
existing VSAT assets.
Minimal
logistic efforts are required to implement the TM1
upgrade, and the quick ROI payback is estimated at 5-7 months.
The Ayecka
TM1 is a unique trans-modulation device designed as a
practical and trouble-free way to migrate existing VSAT networks
to DVB-S2. The TM1 is an indoor unit simply installed by
the end user between the LNB and the VSAT.
The TM1 operates as a transparent and integral
upgrade to the network. The TM1 makes it simple and
cost effective to migrate to the more efficient DVB-S2 standard,
thus leveraging the current investment in the VSAT network.
Why DVB-S2 ?
DVB-S2 is the
second-generation standard for satellite broadcasting, which is
now widely adopted. The new specification benefits from recent
developments in channel coding (LDPC codes) combined with a
variety of modulation formats (QPSK, 8PSK, 16APSK and 32APSK).
This more efficient technology yields increased transmission
capacity along with an approximately 30% improvement in space
segment utilization.
