Ten questions on transmodulators, the professional devices that transform satellite channels into DTT and IP to be able to see them on any TV, PC or smartphone without the need for additional decoders and CAMs.Do you have any further doubts?Write to us and our experts will get back to you.It is a device that transforms one type of modulation into another.In satellite systems, it converts the original DVB-S / S2 (QPSK or 8PSK) modulation into DVB-T / T2 (QPSK or QAM), without modifying either the content of the satellite transponders (TV, radio and service channels) or their quality (with the same available bandwidth).In practice it allows you to receive satellite channels with a TV or decoder with DVB-T / T2 MPEG-4 terrestrial tuner.They are used in community structures such as hotels, hospitals and even large condominiums because they avoid spending thousands of euros in the purchase of televisions and decoders with DVB-S / S2 tuners, without counting the costs related to the installation and maintenance of each individual. device.The DVB-T HD modulator transforms a video signal into a single DTT and multiplex channel while the transmodulator performs the conversion of the modulation and transmission technology (from Sat to DTT, from Sat to IP, etc.) of one or more multiplexes, transponders and satellites.The transmodulator essentially allows you to distribute many more channels with related services (teletext, audio, subtitles, etc.).Yes. OFDM-OFDM transmodulators are equipped with two DVB-T / T2 tuners and as many T / T2 outputs.Their main function is to reorganize the DTT muxes by changing frequency, other parameters and decoding them (eg: ex Mediaset Premium now Sky DTT) to distribute them in clear text to all the sockets of the system.Another important function is to convert terrestrial signals to make them visible even on incompatible TVs and decoders (eg: from DVB-T2 to DVB-T).Yes. Their function is to allow the reception of DTT and SAT channels in hotels, villages and other community facilities using PC, smartphone, Smart TV and Android TV box.There are IPTV transmodulators with one or more SAT or Mux DTT transponders in input but also HDMI-IPTV converters for video surveillance cameras, decoders, PCs, DVD players, etc.For information, we recommend visiting the Auriga, Offel and Mediasat websites.No. Some models can manage a maximum of 1-2 satellite transponders and therefore distribute all the channels present on these frequencies.Others arrive at 4, 5, 6 and even 9 transponders but the cost grows exponentially (even 8 thousand euros).Indicatively, the number of satellite channels that can be distributed ranges from 10-15 to over 100.Yes. Most transmodulators are equipped with slots for Common Interface modules that decode the encrypted signals "upstream" and distribute the free-to-air signals for free viewing on TVs and DVB-T / T2 decoders, ie without the need for of CAM or smart card.A typical example is the centralized distribution of the tivùsat bouquet made possible by special CAM modules called “Pro”.For more information, visit the dedicated section of the tivùsat website.Yes. When purchasing, it is important to choose only those transmodulators that support as many input transponders as are used by the tivùsat channels, in addition to the support of professional CAM modules for multiple and simultaneous decoding of encrypted channels.There are also “all-inclusive” kits such as those from Televes.However, it is good to consider that in a 4-6 room apartment it is cheaper to buy 4-6 tivùsat decoders or CAMs and bring the SAT cable to all the rooms rather than a transmodulator with tivùsat CAM Pro.No. Unfortunately there are no CAMs that decode Sky channels via satellite on TV and Common Interface decoders, neither consumer nor professional.In your case the only solution is to install up to 4 Sky Q Mini decoders in the various rooms, all managed by the main Sky Q Platinum decoder via Wi-Fi or Ethernet cable (if available).With 4 Sky Q Mini and one Sky Q Platinum you will be able to see Sky channels, online content and recordings in up to 3 rooms at the same time (2 Mini and Platinum).A transmodulator is much more expensive than a DVB-T HD modulator: prices start at around 600-700 euros for the most basic models (2 inputs / 2 Sat transponders and 2 DTT muxes out) and can exceed 4000 euros for a system complex suitable for the distribution of tivùsat channels in the hotel.The cost can increase further if you add optional modules and accessories such as input multipliers, CAM slots for decoding encrypted channels, etc.Yes. The configuration procedure, i.e. the choice of transponders / muxes to be distributed, the composition of the channels, the output parameters and the analysis of the signals, must be done by professional antennas who have gained some experience in Sat distribution systems. -DTT.An inexperienced enthusiast or a technician without the necessary training could make configuration errors that make the system unreliable or malfunctioning.Save my name, email and website in this browser for my next comment.If you liked this article and want to stay informed about technological news
