Afrequency range (3.70-4.20 GHz) used for satellite broadcasts.
An European committee of the international Telecommunications Union and makes recommendations for the distribution of telephone and data distribution.
The Clarke Belt is a dedicated satellite orbit in which satellites remain in a fixed position relative to the Earth’s surface.
Both names are used for these modules. These modules are PCMCIA cards with a slot in which you can insert a smart card.
A DVB standard which defines the software and hardware requirements for condition access systems.
A system which is used by service providers to control the subscriber’s access to certain services, programs and events like Pay TV.
A signal frequency range
A unit that is connected to a satellite receiver in order to unscramble a picture that is protected by encryption. Standard which describes the method of transmitting digital audio.
A standard through which it is possible to let a DiSEqC compatible receiver send a signal over the RF cable to a switching device to switch between different LNBs or dishes. The DiSEqC uses the 22 kHz signal to control the switching device.
A broadcast standard for digital radio and television, using
A electronic program guide that comes with the broadcast of a particular satellite, Note that every station fills the EPG differently or not, so differences in the EPG are not necessarily receiver errors.
Is an invisible part of a broadcast.which makes sure that possible errors in the reception of the satellite signal are corrected.
A part of the dish which collects the signals from the dish. The signal is then fed to the LNB(F).
A remote controlled device that determines the polarity of the signal which is fed to the LNB. The ferrite is more or less an
A dish antenna that is pointed at one particular satellite. An unscrambled broadcast which you can view without additional payments to a service provider.
A frequency band is a range of frequencies which are dedicate to a certain usage. In the satellite area, commonly known bands are the
A digital television format, which combines
In the satellite industry, horizontal is used to indicate the direction in which the received signal is polarized. Normally you will find that it is abbreviated as H.
A frequency range
A device behind the feedhorn which processes the signal into a format which is understood by the receiver for further processing
A LNB with an integrated Feedhorn. So the LNBF comes as one single unit.
