CATV: abbreviation for Community Antenna Television.75 GHz satellite. DVB (Digital Video Broadcasting): transmission video and sound signals digital form. When receiving from or more satellites the DiSEqC switch required, which controls multi-switches and also receivers. 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.5 ms. Systems with older LNBs cannot receiver the whole range the band (typically only 10. Amplifier: for increasing the aerial signal level Video bit rate: quantity data transmitted per second digital video signal. DiSEqCTM (Digital Satellite Equipment Control): Switching signal generated the satellite receiver, for controlling and switching LNB and multi-switches. For SAT position the kHz signal sent continuously, for SAT position pulsed. Data transmitted this way are however often incorrect incomplete. 27 dB/100m 2,000 MHz and shielding class (class A). digital systems (QPSK) the transmission capacity 6-10 programmes with sound channels. Azimuth: azimuth means the alignment the south-facing satellite aerial (horizontal angle) Band: band denotes frequency range between two specified values. Dolby Digital Sound Processing: this enables digital surround sound reproduced a home cinema system. Data Reduction: compression image and sound signals.g. Field strength meter: instrument used technical staff measure the signal strength a radio channel. Tone-Burst signal lasts for about 12. Each subscriber must able switch between different reception levels, frequency ranges and even different satellites. DAB (Digital Audio Broadcasting): designation for digital radio. Elevation: elevation meant the vertical angle (inclination) the aerial EPG (Electronic Programme Guide): electronic program guide Decoupling attenuation (directional attenuation) attenuation the output sockets relative each other FEC (Forward Error Correction): technique for reducing the error rate data transmission. Twin-Receiver: satellite receiver with two separate independent reception components one box (e.g. The voltage the supply also determines which polarisation plane returned the LNB. Data compression carried out using MPEG-2. Tone-Burst: type Mini-DiSEqC has been defined economical way extending old systems wider circuit configuration (in addition 14/18 Volt and kHz). "normal" (terrestrial) domestic aerial can receive and radio programmes. CATV bands BK bands Band (VHF), channel 4 Band (UKW), frequency 87. Carrier: wave very high frequency, which means modulation able convey radio or TV signal over very great distance. Free-to-Air: free-to-air receivers receive exclusively free (non-encrypted) programmes. d) Instructions for coaxial cables d r d 18 8 Stripping length for aerial socket Directional attenuation Attenuation between trunk output out and the output sockets Decoupling Attenuation between two aerial sockets.g. expressed degrees and depends the design and size the SAT aerial. Redundant information left out.

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. For satellite transmission two different planes are used: the horizontal and the vertical (linear polarisation), the better exploit the frequency spectrum. DVB-S stands for satellite cable transmission, DVB-T for terrestrial cable transmission and DVB-C for cable transmission. Ku-Band: satellite transmission frequency band SAT-bands: (SAT-IF, Input-IF) intermediate frequency bands used satellite receivers: 950 1,750 MHz (standard band) 950 2,050 MHz (extended band) 700 2,050 MHz (further extended band) High band frequency range 11. DiSEqC trade mark the European Satellite Organization (EUTELSAT) and arose out cooperation between EUTELSAT and Phillips. The interference that could result prevented polarising the two channels in different planes. the band the relationship is: transmission frequency the satellite LOF receiver reception frequency MPEG-2: data compression process for images and sound. QPSK (Quadrature Phase Shift Keying): digital modulation process used for satellite transmission. For this, an electronic changeover switch required, which called multi-switch (up 100 subscribers). Power Supply: the satellite receiver supplies the LNB with power via the coaxial cable. This can for example provided modem incorporated within the digital receiver. distributors, aerial sockets etc. The outer conductor (shield) serves protect the inner conductor against external interference, and thus minimises the signal loss the inner conductor. Pass-through attenuation: reduction the signal level each output, e. Concentrates the electromagnetic waves the feed system (LNB). contrast conventional analog technology (where full images with all information are transmitted per second) the MPEG process deals with only the actual changes the image.
