Request for a quote


TM1-Pro converts DVB-S2 signals to DVB-S and solves the dilemma between the benefits of the DVB-S2 and the cost of migration. As an optimized and reliable device, the integration of TM1-Pro with existing receivers (DVB-S VSAT or IRDs) is quick and simple both for data and video networks.


  • Conver DVB-S2 signal to D VB-S
  • Advanced DVB-S2 front end – 16/32 APSK
  • 30% saving with CCM and up to 70% with ACM
  • Ideal for VCM (C-Band ) and ACM ( Ku-Band)
  • Rx symbol rate from 400 ksps to 45Msps
  • Ayecka patent for SNMP MIB for Uni-Directional device

The TM1-Pro converts DVB-S2 signals to DVB-S allowing use of DVB-S receivers with DVB-S2 links. Integration of the TM1-Pro with existing receivers (VSAT or one way) is quick and simple. An operator need only configure the IRD to receive an L-Band input of 1Ghz at 27Msps. The TM1Pro is configured according to the satellite signals parameters.

TM1 Pro is the optimal solution for upgrading existing 8PSK DVB-S2 networks to 16APSK, or existing CCM DVB-S2 to ACM or VCM.

The TM1 Pro was designed to simplify the upgrade process - both in cost and time.

Why DVB-S2?

DVB-S2 is the second-generation standard for satellite broadcasting, which has been widely adopted by the broadcasting industry. The new standard benefits from recent developments in channel coding (LDPC codes) combined with a variety of modulation formats (QPSK, 8PSK and 16APSK). This more efficient technology yields increased transmission capacity along with ~30% improvement in space segment utilization.

DVB-S2 provides VCM and ACM mode to optimize channel utilization by variable coding per packet.

The DVB-S2 Migration challenge

Companies which have invested in DVB-S based VSATs are facing a situation where this technology may become obsolete due to the onslaught of the new DVB-S2 technology. The new-generation DVB-S2 technology offers several advantages over DVB-S, the main ones are 30% savings in bandwidth and support for multi stream.

From a technical perspective, existing DVB-S VSATs can continue to provide most of the services like Return channel and Routing, It is the receiver that has to be upgraded.
