Transmission and distribution of HDMI signals
HDMI is now the most commonly used connector in sources of different kinds of multimedia content. In situations where there is a need to send an HDMI signal at a distance greater than 30 meters (maximum length of HDMI cables), or in a place where such a cable cannot be installed, it is reasonable to use the appropriate media converter that allows the transmission of the signal from the HDMI source using other type of transmission cable, more suitable for that application.

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 ...

Coaxial cables recommended for SMATV and HFC/CATV systems
SMATV systems based on multiswitches are multi-cable installations, with different signals in each cable and long cable sections (up to hundred or so meters, depending on the size of the multifamily building). So, there is a risk of crosstalk effects (inducing interference in neighbor cables) that would deteriorate the performance of such systems. To avoid crosstalk between coaxial cables going in parallel, they should fulfill requirements for A, A+ or A++ class.

How to select an antenna for digital TV (DVB-T)
The implementation of digital terrestrial television (DVB-T) in Poland and some other European countries is at the turning point. Alongside with the new digital transmitters and successive multiplexes, there are still available analog channels. Although in most cases the reception of DVB-T does not require replacement of the antenna array used to date for analog TV, the practice shows that in many situations the modernization of the array is necessary. This is mainly linked with a lower power of some digital transmitters in the transitional period, due to the simultaneous operation of analog ...

Digital DVB-T modulators - assortment and applications
Conversion of baseband audio-video (A/V) signals into radio frequency (RF) channel is called modulation. This process allows for distribution of the signals coming from all kinds of sources, such as computers, DVD players, security cameras etc. through antenna systems. The device used for this purpose (modulator) is equipped with one pair or a set of A/V inputs (SCART, RCA, HDMI) and RF output. The output signal injected into the antenna system is available in the distribution network as additional TV channel (or multiplex - in the case of DVB-T modulator and two or more A/V signals) that can ...

Digital satellite broadcasts
Thanks to digital technology, satellite industry has increased the number of channels that are broadcast from one transponder - there may be transmitted 5, 8, or even more TV programs. It lowers operating costs and makes possible to multiply the offer from a single satellite. The important factor is compression level that can be changed according to the intended quality of the image.

Antenna signal measurements
Most of parameters can be measured using selective signal level meters. Performing such measurements is not a waste of time but essential stage for proper design, and, the next - even more important - of verification of the work done. The measurements allow to verify correctness of the design and its implementation, as well as quickly find the errors arising both at concept and realization stages.

Choosing a multiswitch...
The choice of a multiswitch depends on the number of users, received satellites and bands, and employed converters (LNBs). We have worked out table and diagrams, which are useful for those who want to crystallize their plans of building SMATV system. As example multiswitches we mainly present Terra devices, although the instances given can be considered as a general concept.

Switches, combiners and diplexers used in individual satellite installations
Nowadays individual satellite installations are rarely used for receiving channels from one satellite only, with one satellite receiver. Most of users prefer to have access to a variety of programs from two or more satellite positions, so that next converter/s (LNB) will have to be installed. The most common situation is reception from two satellites, which requires installation of two converters and a switch.

Satellite converters - LNBs
Satellite converter (often called LNB - Low Noise Block) is the device used for amplification and transition of signals from the ranges 10.7-11.7 and 11.7-12.75 GHz into the band of first intermediate satellite frequency (IF - 950-2150 MHz).

Theory and use of channel amplifiers
A common problem that is encountered in terrestrial TV antenna installations is unbalance of the level of received channels, often about 10-20 dB. In case of small installations (5-20 outlets) such a difference (not recommended) usually doesn't make any trouble yet. It is the real problem for bigger installations, where the difference of levels at the input is increased by inconstant (being a function of frequency) attenuation of cables and may easily exceed (in an outlet) the accepted limit (12 dB) all over the band.

Splitters and taps
To ensure proper S/N ratio, the isolation between any two receivers should be at least 50 dB.When the receivers are connected to the same tap, the isolation depends on the Ao, A, and As attenuation, and the lengths of the cable between tap outputs and subscriber outlets.
