Terra TTQ-440 R81622 DVB-T to DVB-C transmodulator is used for reception of DVB-T signals and retransmission of them in QAM format in chosen RF channels. The TTQ-440 R81622 panel can receive four FTA DVB-T/T2 (COFDM) multiplexes and convert them into four neighboring DVB-C multiplexes that can be received by any common televisions equipped with DVB-C tuners. 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 channels, including HD broadcasts.

Thanks to RJ-45 Ethernet port, the programming of the TTQ-440 R81622 panel is performed via a web browser.

A great advantage of the Terra device is easy integration with other components:

IPTV streamers for management and distribution of satellite, terrestrial and cable DVB channels within Ethernet (LAN) networks based on twisted-pair cabling,
optical transmitters for transmission TV programming via optical links,
other receiving and signal processing devices (broadband and channel amplifiers, analog and digital modulators),
compact digital headend S2C16 - S2C16 R81620 converting DVB-S/S2 (8PSK/QPSK) broadcasts into DVB-C (QAM) multiplexes.

The R81613 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.

Key features

conversion of DVB-T/T2 signals to DVB-C QAM standard,
conversion of four DVB-T/T2 multiplexes to 4 neighboring DVB-C multiplexes,
automatic gain control (AGC),
easy control via RJ-45 port,
management via the Internet,
access to event history (logs),
RF loop.
