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.

Increasing availability of multimedia content presses demand for high quality transmission between the sources (transmitters) and players (receivers) of the content. Extensive multimedia systems in hotels, restaurants, clubs etc. require appropriate equipment to create suitable networks providing the content to multiple flat screens.

Signal HD converters of HDMI (or VGA) to IP interface allow users to transmit and distribute high-resolution (HD) signals via computer IP networks to HD-enabled televisions/monitors (with HDMI or VGA inputs). They also enable users to control the source devices from the remote locations of the televisions/monitors through the original remote controls or, where applicable, through USB devices (mouse and/or keyboard – e.g. in the case of STBs and NVRs).

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.

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.

Signals from cameras in TV/SAT systems. The conversion of A/V signals into high-frequency RF signals, meaning the introduction of signals from all kinds of signal sources, such as computers, players or surveillance cameras, into a terrestrial TV system, is an operation that requires the use of a so-called modulator. Such device has one or multiple A/V inputs (HDMI) and an RF output (commonly known as the "antenna output), and it allows you to watch the video and listen to the sound on the selected channel , on all TVs connected to the system. For the receiver, the program added to the system is just another terrestrial television channel.

Two Quatro LNBs (A98257) are connected with R70808 multiswitch (via eight coaxial cables TRISET-113 E1015). In the diagram below, the inputs of the multiswitch connected with the second LNB (for a second satellite) are not visible (they are physically placed in the second row, behind the first). The use of a twin-tuner PVR receivers requires installing two TRISET-113 E1015 cables from the multiswitch to the R694140 outlets. This will enable simultaneous viewing of one program and recording of another. The diagram shows two "single" receivers and one twin-tuner receiver.

The elegant and functional RACK cabinets are designed for mounting devices having housings compatible with 19" rack standard (482.6 mm). The height of the devices and auxiliary equipment is standardized as the multiplies of one rack unit ("U" = 1.75" = 44.45 mm). The capacity of a RACK cabinet is determined by its height also given in "U" units. Another important parameter of a RACK cabinet is its depth (external dimension), given in millimeters, e.g. 450 mm, 600 mm, 800 mm. This parameter is especially important for larger devices, such as computers, DVRs. It is important to know the depth of the devices and the necessary space for cabling, in order to choose a suitable cabinet.

Digital terrestrial television (DVB-T/T2) covers the whole Europe. These several examples of DVB-T antenna systems will help anyone who wants to build a new antenna system or upgrade the existing one. The antenna installations presented below are a set of options that can be selected depending on the power of the transmitter and its distance to the reception point, as well as specific requirements of the user(s).

PROTECT line consists of portable DVR cameras dedicated for indoor use (including applications in vehicles). High quality video captured by the cameras and audio from the built-in microphones are directly recorded on the inserted memory cards.
