9 Technical Terms

Antenna cable:

Connecting cable from the modulator of the satellite receiver to the antenna input socket of the television set; used as an alternative where no SCART socket is available

Coaxial cable:

Connecting cable between LNB and satellite receiver, used to transmit the signal received, as well as to supply the LNB with power

Data compression/MPEG1/MPEG2:

To transmit the current television standard (625 lines repeated 50 times per second) results in a digital data volume of 216 MBit/s. This would require bandwidths that cannot be provided by either terrestrial or satellite sources. The volume of data is thus compressed by electronic means to reduce the volume. In Europe, the MPEG-2 standard has been laid down as the international standard for data compression. MPEG2 is a further development of MPEG1

Deemphasis:

Adaptation of the audio frequency profile to the broadcast signa, this is defined by the broadcast parameters of the satellite

DiSEqC:

Digital Satellite Equipment Control: a digital switching system used to control DiSEqC-compatible components of the extenbal installation via the antenna cable.

DVB:

Digital Video Broadcasting: a universal digital broadcast standard used for all possible types of data, such as pictures, graphics, sound and text, in an appropriate form providing appropriate quality

External unit:

Description used for the complete system mounted outdoors, consisting of parabolic dish antenna, as well as one or more LNBs, used to receive signals from one or more satellites

Frequency:

Physical measurement, indicated the number of wave-cycles per second, expressed as Hertz (Hz)

Frequency range:

a) Satellite resp. LNB:

11 GHz range from 10,70 GHz to 11,70 GHz, 12 GHz range from 11,70 GHz to 12,75 GHz
