Key features
  • conversion of DVB-S/S2 signals from eight SAT transponders to DVB-T COFDM standard,
  • creation of four neighboring DVB-T multiplexes, each with max throughput of 31.66 Mbps,
  • selectable channels and services,
  • cooperation with dSCR/Unicable multiswitches,
  • easy configuration and control via RJ-45 port,
  • management via the Internet,
  • access to event history (logs),
  • automatic gain control (AGC).
Terra TDX-440 R81614 DVB-S/S2 to DVB-T transmodulator is used for reception of DVB-S/S2 (8PSK/QPSK) signals, selection of desired channels and retransmission of them in COFDM format in chosen RF channels in VHF/UHF frequency range. The device allows the user to receive and manage a range of free to air satellite channels. One TDX-440 R81614 panel can receive channels from eight satellite transponders and convert selected channels into four neighboring DVB-T multiplexes, each with maximum throughput of 31.66 Mbps. In practice, each of the four multiplexes can carry 6 SD channels or 2-3 HD channels. The administrator of the system selects the required channels from the satellite streams and forms four DVB-T multiplexes. In each case, it is neceeesary to remember about 10% safety margin when determining the maximum bit rate for the whole multiplex (typically the ultimate bit rate of a multiplex should not exceed 29 Mbps). The output DVB-T COFDM multiplexes are usually distributed to users by a passive network composed of RF splitters/taps. Such a solution is especially convenient in modern hotel TV systems distributing a variety of satellite channels, including HD broadcasts.
Thanks to RJ-45 Ethernet port, the programming of the TDX-440 R81614 panel is performed via a web browser.
The TDX-440 R81614 unit is dedicated for receiving FTA satellite channels. In the case of encrypted channels, the suitable model is TDX-420C R81619.
A great advantage of the Terra device is easy integration with other components:
The R81614 units can be mounted on the R82538 or R82539 DIN rail (also in a RACK cabinet) and powered from DR-60-12 R82532 or UP413 R82533 power supply.

The TDX-440 R81614 transmodulator creates four neighboring DVB-T multiplexes with channels selected from eight satellite transponders. With these parameters, the maximum bandwidth of each of the four DVB-T multiplexes is 31.66 Mbps, in compliance with the DVB-T standard.
