Details

Terra TDX-420C R81619 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 and encrypted satellite channels (CI/CAM compatibility). One TDX-420C R81619 panel can receive channels from two satellite transponders and convert them into two neighboring DVB-T multiplexes with maximum throughput of 31.66 Mbps. In practice, each multiplex 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 two DVB-T multiplexes. Alternatively, one DVB-T 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 29 Mbps). When a higher throughput is required, the system should be equipped with additional TDX-420C R81619 unit(s). 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-420C R81619 panel is performed via a web browser.
The TDX-420C R81619 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:

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.
