ABSTRACT:
A typical satellite reception system comprises a satellite dish, a low noise block (LNB) and a satellite receiver. The low noise block converts the received signals into lower frequency signals which are fed to the satellite receiver. It is now becoming increasingly desirable for STBs to be fitted with two or more tuners, each having an associated receiver/decoder. This is to allow, for example, a user to watch a satellite television program whilst recording, on a video recorder, a different satellite television channel. However, since a single LNB can only supply signals from either a vertically or horizontally polarised signal, it is not possible to use a single LNB to provide all the desired portions of the incoming satellite signal.
