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.
