Detaily

Terra TDQ-420C R81639 DVB-S/S2 to DVB-C transmodulator is used for reception of DVB-S/S2 (8PSK/QPSK) signals, selection of desired channels and retransmission of them in QAM 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 and encrypted satellite channels (CI/CAM compatibility). One TDQ-420C R81639 panel can receive channels from two satellite transponders and convert them into two neighboring DVB-C multiplexes with maximum throughput of 53 Mbps (no PID filtering). In practice, each multiplex can carry 8 SD channels or 4-5 HD channels. The administrator of the system selects the required channels from the satellite streams and forms two DVB-C multiplexes. Alternatively, one DVB-C multiplex can be programmed from channels coming from two different satellite transponders. 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 50 Mbps). When a higher throughput is required, the system should be equipped with additional TDQ-420C R81639 unit(s). The output DVB-C QAM 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 TDQ-420C R81639 panel is performed via a web browser.
The TDQ-420C R81639 panel has two CI slots that in the case of receiving encrypted programs must be equipped with suitable conditional access modules (CAM) with dedicated smart cards.
A great advantage of the Terra device is easy integration with other components:
Customers can also order DVB-S/S2--> DVB-T (COFDM) transmodulators:
  • DVB-S/S2 (8PSK, QPSK) to 2xDVB-T (COFDM) Terra TDX-420C R81619 (two CI slots)
  • DVB-S/S2 (8PSK, QPSK) to 2xDVB-T (COFDM) Terra TDX-420 R81618

Example of mounting TERRA headend to CD001 housing with DIN rail BD001 R90001. Additionally, there are the SRM-522 R80522 multiswitch and an Ethernet switch mounted on the ID001 R90003 mounting plate. The whole system has the FD001 R90002 ventilation unit with thermostat added.
Set of ttx410C R81615 and tdx410C R81617 transmodulators used in an SMATV system. For the reception of pay-TV channels it is necessary to install suitable conditional access module.
Notice: The transmodulator is compatible only with CI CAM modules (no support for CI+).

Hotel TV system based on conversion of encrypted DVB-S/S2 channels to DVB-T standard

  • 2018-02-12

Digital headends distributing satellite channels converted to DVB-T COFDM form have become popular solutions in hotels. The TERRA system has been designed for building TV distribution installations providing signals to standard televisions with built-in DVB-T tuners and allowing reception of terrestrial (DVB-T) and satellite (DVB-S/S2) channels without additional receivers/STBs. The output RF signals in the single DVB-T COFDM standard are distributed to outlets in rooms via typical coaxial cabling.
