IP to 4x DVB-C Transmodulator: TERRA miq-440 (100/1000Mbps, USB port)

TERRA miq-440 R81631 transmodulator converts IP stream (TSoIP) provided in UDP/RTP protocols (unicast/multicast SPTS and MPTS transmissions) and RTSP stream (from IP cameras) to DVB-C QAM standard. One miq-440 R81631 panel receives IP stream with bit rate up to 200 Mbps and creates 4 freely configurable neighboring DVB-C multiplexes, each with maximum bit rate up to 53 Mbps (the limit is determined by the DVB-C standard). In practice, each of the four multiplexes can carry 8 SD channels or 4-5 HD channels. The administrator of the system selects the required channels from the IP stream and forms the four DVB-C MUXes. 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 48 Mbps). 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 miq-440 R81631 panel is performed via a web browser (no need for a programmer).

The transmodulator can be integrated with other components:

The R81631 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.
