DVB 2 DVB = Transmodulation

A transmodulator does nothing more than convert a DVB reception process from satellite to cable network.
A typical and compact application is a hotel with existing coax cabling as a tree structure. Since modern TV sets are usually equipped with multi-tuners, the existing cable network can be used. Considerable conversion costs are saved, as SAT networks have to run in a star configuration and each TV connection needs its own line.
With the cable network, the signal is usually looped through from box to box and can thus be forwarded in a row. With the HDC-7024A, satellite TV DVB-S(S2x) is converted to cable TV in digital quality in DVB-C without loss. Not only do the SAT high frequencies and bands have to be converted, but also the bandwidths and their limits. and the bandwidths and their limits (DVB-C maximum = approx. 50Mb/s) must be taken into account, but also the internal DVB-PSI/SI MPEG tables, which enable the fast tuning of the TV receivers.
The conversion of the 24 transponders into 16 DVB-C QAM channels is a cost-effective variant in a unit that can transmit international TV and radio content - e.g. from ASTRA and Eutelsat - to the rooms, lobby and bars/restaurants into the existing TV network.

The BLANKOM HDC-7024A is a 5th generation SAT, ASI & IP to DVB-C QAM CATV cable TV modulator with multiplexer and scrambler.
The IPTV input channel Streams serves multicast SPTS or MPTS. The internal multiplexer creates 16 RF + Streams with any combination of content.
The output consists of 16 DVB-C carriers within 192MHz bandwidth, each with up to 256QAM modulation. Each of the 16 output multiplexes are also provided as MPTS IPTV streams, UDP/RTP/RTSP, unicast or multicast at the corresponding data port.

The BLANKOM HDC-7016A is a 5th generation SAT & IP to QAM modulator with multiplexer and scrambler. The IPTV input channels can be SPTS or MPTS, unicast or multicast.
The internal multiplexer creates 16 RF + streams with any combination of content.
The output consists of 16 DVB-C carriers within 192 MHz bandwidth, each with up to 256QAM modulation.
Each of the 16 output multiplexes are also provided as MPTS IPTV streams, UDP/RTP/RTSP, unicast or multicast at the both data ports.

The BLANKOM HDC-6008CI is a cost effective SAT->QAM TransModulator with SAT & IP to DVB-C QAM including multiplexer and descrambling with 4x CICAM slots.
Equipped with 8 DVB-S/S2 tuner inputs, 4 CI slots for CAMs, 4 groups multiplexing with scrambling, it supports maximum 128 IPTV inputs via GE port and outputs 4 adjacent carriers (50MHz...960MHz) combined via RF output interface in parallel to 4 MPTS outputs. BLANKOM HDC-6008CI also features high integration level, high performance and effective cost. Dual power supplies for redundant power supply is optional. This device is perfect for flexible and/or additional cableTV headend concept.
