The present document applies to InDoor Units (IDUs) for satellite broadcast reception. An indoor unit gets on an input interface the signal that has been received from satellite and processed by the OutDoor Unit (ODU). It performs carrier selection, demodulation, audio and video decoding.
IDUs in the scope of the present document demodulate broadcast carriers by means of a Zero IF tuner.
Part of the IDU functionality may be integrated with the ODU. In that case the present document applies to this part of functionality as well as the remaining part in the IDU.
The indoor unit may be integrated with a domestic television receiver.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
