Digital DVB-T modulators – assortment and applications

The conversion of baseband audio-video (A/V) signals to radio frequency (RF) channel is called modulation. The process allows for the distribution of signals coming from all kinds of sources, such as computers, DVD and Blu-ray players, security cameras etc. through antenna systems.

Modern multiswitch installations – Signal MRP

Signal MRP multiswitches with passive DVB-T/DAB/FM path have been designed for small/medium size SAT installations built in star topology. One device or a group of such multiswitches feeds the subscriber outlets from individual outputs of the multiswitch(es). This topology is typical for applications in single-family homes and in buildings inhabited by several or so families.

Designing FM/TV and SAT TV distribution systems in multi-dwelling units

The article introduces concepts of implementing distribution systems of terrestrial and satellite radio and TV signals in multifamily buildings. Any subscriber is able to receive terrestrial FM/DAB/TV signals broadcast in the area, and satellite radio/TV signals from two satellite positions. All the signals come from one master antenna set...

Single-cable multiswitches -TERRA dSCR (Unicable system)

Legacy multiswitches operate in the 950 to 2150 MHz range and together with a Quatro LNB allow for distribution of DVB-S/S2 satellite programming, DVB-T terrestrial broadcasts, analog FM/ radio broadcasts from one master antenna set to many DVB-S/S2 receivers, TVs, stereos. The job of a multiswitch is to enable any satellite receiver in the system to tune to any satellite channel (polarization/band pair) across the whole range of satellite reception. For this purpose, such a receiver sends via its input and coaxial cable suitable commands (14/18 V supply voltage, 0/22 kHz switching tone, and, in the case of 9-input multiswitches, DiSEqC control signal). The result of the commands is the selection of the adequate input of the multiswitch connected to its output (connected with the input of the receiver).

Hotel TV systems - headends and amplifiers

One of the criteria for classification of TV systems in hotels is the programming to be distributed. The simplest systems may provide only free-to-air terrestrial TV broadcasts, whereas more advanced solutions will include satellite channels, also some premium ones (pay-TV). The content required by the owner/investor will depend on the categories of prospective hotel guests (foreign and thematic channels etc).

Fiber-optic TV systems

Under EU rules, by 2020 each citizen of the European Union is to have the technical ability to access the Internet with download speed at least 20 Mbps. In this respect, some EU countries introduced regulations aimed at accelerating this process. In some of them, each newly built residential building should be equipped with fiber-optic infrastructure. This type of cabling can be used not only in the implementation of access to high-speed Internet, but also proves to be an excellent medium for other services, including distribution of TV/SAT programming. Multiswitch systems providing access to digital terrestrial television (DVB-T) and satellite TV platforms are the perfect complement or an alternative to cable TV networks in multifamily buildings. The use of fiber optic solutions for such SMATV systems can have both technical and economical advantages.
