Satellite Receiver
A satellite receiver is a unit which takes signals from
the LNB(s) and decodes the TV video and audio so they
can appear on TV. Because both C-band and Ku-band LNBs
normally have the same output frequency, which is from
950 - 2150 MHz, a receiver shall be capable of receiving
either C-band or Ku-band programmes.
An analogue receiver is needed for the reception of analogue
channels whereas a digital receiver to receive digital
channels. To watch television channels that are encrypted
or conditional access, you need a special Integrated Receiver
Decoder (IRD) which is normally supplied by the broadcasters
or cable operators.
Since a domestic satellite receiver is designed for 1:1
reception, i.e. one input and one output, you need more
receivers and use a n:1 AV selector to collect all signal
inputs if your system has more than one incoming signal
e.g. dual polarization or dual band.
