Designing a failure-free RTV-SAT installation requires components with the highest specifications. Here you will find strategic solutions for building, optimizing, and servicing distribution infrastructure. From precise signal reception from satellites and terrestrial broadcasts, through active level management systems and fiber-optic transmission, to technologies that minimize cabling. We guarantee access to every element: from converting and modulating units to low-attenuation protective accessories. We focus on scalability and maintaining a crystal-clear MER parameter at the endpoint.
Fiber-optic systems are the only solution for installations over large areas (campuses, residential estates), guaranteeing zero signal attenuation loss over distances of several kilometers. The use of optics eliminates the risk of ground loops and electromagnetic interference, which is crucial for failure-free operation in critical systems (e.g. in medical technology).
A multiswitch is a tool for professional signal aggregation, allowing you to quickly create an integrated SAT+DVB-T offer that meets all the requirements of modern communal installations. Designing a network in Wide Band architecture enables a 50% reduction in cabling in building risers, shortening installation time and improving the aesthetics of the work.
The implementation of high-gain distribution amplifiers ensures precise compensation of cable losses, giving confidence in the required signal level at distant points. The use of professional LTE/5G filters enhances the installer's credibility by solving interference problems without the need for costly return visits to the customer.
Selecting an LNB converter allows you to significantly reduce costs and working time, enabling quick multiroom deployment on existing single-cable infrastructure. The use of models with high separation and high gain (LNB Quad/Octo) guarantees a stable CNR (Carrier-to-Noise Ratio) parameter, minimizing later service requests.
HDMI modulators give the installer the ability to create added value for the business customer (the hotel's own information channel), expanding the range of services offered. The use of headends allows centralized control over licenses and decoders, simplifying Pay TV service management for hundreds of hotel rooms.
Signal path optimization starts with antenna selection, which must ensure the required signal margin (MER/BER). In DVB-T2/HEVC scenarios, precise selection of the gain and directionality of the terrestrial antenna for the given electromagnetic field is crucial. For satellite reception, it is essential to use the appropriate dish size for the desired transponders. Regardless of the type of installation, proper grounding and mechanical stability of the structure must be ensured.
The selection of the demodulation unit is critical for network compatibility. Tuners must be stable and support the HEVC codec in the DVB-T2/S2X standards. The use of Combo tuners integrates terrestrial and satellite signals, minimizing the number of end devices. Linux Enigma 2 tuners are chosen for projects requiring an open API and customization. Android TV BOX allows integration with the IP network and VOD services.
LNB defines the scalability of the installation and the maximum number of independent subscribers. LNB Quatro or WideBand converters are mandatory as the basis for multiswitches in communal installations. The use of LNB Unicable allows support for up to 32 tuners on one cable, optimizing modernization. Octo converters are the maximum multiroom solution without the need to use active distribution.
A multiswitch is an active element of the distribution backbone, responsible for collision-free distribution of the full band to subscribers. The choice of 5x or 9x architectures depends on the number of required orbital positions. In modern projects, choose Wide Band multiswitches or Unicable multiswitches, which reduce cabling. Using NET Class units guarantees low noise and stability in cascade installations.
It is crucial to use components with high separation and low attenuation throughout the system. Passive components such as taps and splitters must be precisely selected to ensure an equal signal level at every outlet. Signal combiners and DiSEqC switches allow flexible signal management. Surge protection is essential for protecting expensive active electronics.
Integrating Pay TV requires the implementation of content decryption solutions. CI/CI+ modules are preferred because they eliminate the need for an external decoder, integrating decryption with the television. Prepaid TV is optimal for seasonal installations due to the prepaid model. The compatibility of the module and card with the operator's encoding system should be verified.
Implementing closed RTV networks (In-House Channels) requires modulation units and headends. Digital HDMI/DVB-T modulators convert signals from non-standard sources into a television transmission standard. Modular compact headends are used for selective transmodulation and processing of dozens of SAT transponders. IP, IPTV to DVB-T/C solutions integrate network content with traditional cable infrastructure.
Optical transmission is the only solution that eliminates the high attenuation of coaxial cables over long distances. These systems are crucial in extensive installations (e.g. campuses), where they guarantee zero-attenuation signal transmission over kilometers. Optical receivers convert the light pulse back into an electrical signal, ensuring complete immunity to electromagnetic interference.
Modularity is key for servicing and adapting subscriber equipment. A replaceable tuner head enables quick and economical repair of the reception path. USB-WiFi adapters allow wireless integration of the tuner with the LAN network, which is essential for VOD and IPTV functions. Accessories support diagnostics and expanding the functionality of existing end units.
Wide Band technology optimizes spectral efficiency and reduces cabling. The use of LNB Wide Band and dedicated multiswitches reduces the number of cables from the antenna to two, lowering installation costs. This forms the basis for highly scalable networks based on the Unicable II (dCSS) standard, which is the future of communal installations.
