Data Reduction: compression image and sound signals. Distributor: for distributing the energy incoming main trunk cable into two more trunk cables. For satellite transmission two different planes are used: the horizontal and the vertical (linear polarisation), the better exploit the frequency spectrum. DiSEqC trade mark the European Satellite Organization (EUTELSAT) and arose out cooperation between EUTELSAT and Phillips. Used internationally cable networks cable television or broadband cable networks. DVB (Digital Video Broadcasting): transmission video and sound signals digital form. Here mostly only digital programmes are broadcast. "normal" (terrestrial) domestic aerial can receive and radio programmes. Data Rate: data bits transmitted per second. Transponder frequency containing multiple channels.Attenuation between trunk input and the output sockets. Dolby Digital Sound Processing: this enables digital surround sound reproduced a home cinema system.5 ms. BER (Bit error rate): denotes the quality data signal after has been receives and demodulated. Field strength meter: instrument used technical staff measure the signal strength a radio channel.

The lower the rate, the better the signal. QAM (Quadrature Amplitude Modulation): digital modulation process with phase shift keying, used for transmission cable networks. Switch: for combining splitting frequency ranges and individual channels. Free-to-Air: free-to-air receivers receive exclusively free (non-encrypted) programmes. Single-cable system: matrix for distributing 1. List the most used designs for parabolic mirror satellite (reception) aerials. Gain the opposite attenuation. Amplifier: for increasing the aerial signal level Video bit rate: quantity data transmitted per second digital video signal. Network Search: some transponders receive within the digital data stream list with the data for other transponders, for example facilitate search for all programmes provider, which may occupy several transponder frequencies. expressed degrees and depends the design and size the SAT aerial. Systems with older LNBs cannot receiver the whole range the band (typically only 10. 14 Volt vertical, Volt horizontal polarisation planes.g. The Tone-Burst signal was developed permit simple changing over between two LNBs and suitable for controlling relays (two inputs one output) and for the new Monoblock LNB.T61 Antenna technology terms Tap: for connecting one more branch cables continuous trunk cable. This can for example provided modem incorporated within the digital receiver. The gain aerial depends the diameter of the parabolic mirror and its efficiency. CATV bands BK bands Band (VHF), channel 4 Band (UKW), frequency 87.g. The outer conductor (shield) serves protect the inner conductor against external interference, and thus minimises the signal loss the inner conductor. ADR (Astra Digital Radio): digital audio radio programmes subcarrier analog transponder. The larger the better! Coaxial cable: shielded cable with inner and outer conductor, insulated from each other a material (solid cellular PE), which ensures very small signal loss. Carrier: wave very high frequency, which means modulation able convey radio or TV signal over very great distance. Reception unit the focus the parabolic mirror, which converts the high-frequency satellite downlink into 1. Multi-switch: conventional distributors are insufficient distribute satellite signals. The system based the bands for two adjacent channels being positioned they partially overlap each other. The same instrument can used for precise alignment the aerial that the maximum signal strength achieved and for the checking the signal level connections to community systems. The system offers additionally capacity for data transmission.75 GHz satellite. CATV: abbreviation for Community Antenna Television.
