1. A receiving unit comprising:
- a tuner module tuning a satellite signal;
a demodulator demodulating the satellite signal to form a transport stream signal;
an IP encapsulation module generating an IP encapsulated signal from the transport stream signal;
a decoder module decoding the IP encapsulated signal to form an analog signal; and
a modulator modulating the analog signal and communicating the modulated signal to a television tuner.

Abstract
A receiving unit 28 includes a tuner that receives a first signal that may include a satellite signal. A demodulator demodulates the satellite signal to form a second signal. The second signal may be internet protocol (IP) encapsulated to form an IP encapsulated signal. The IP encapsulated signal may be communicated through an IP network to a decoder. The decoder 144 decodes the second signal or the IP encapsulated signal. A modulator 146 modulates the decoded signal which is communicated to user devices through a network 147. In addition, IP encapsulated signals may also be communicated to various user devices through the network.
