摘要
According to an embodiment of the present invention, the home controller receives signals from a cable television system and utilizes a cable demodulator that is tuned to the RF frequency of the channel carrying the data information. The cable demodulator demodulates the RF encrypted signals into conventional baseband digitized signals, which are sent to a packet receiver that demodulates packets addressed to each user. If a packet has been addressed to an associated user, the packet receiver forwards the corresponding data to the user's personal computer, for example via an Ethernet transceiver. The communication controller provides a connection of the cable demodulation period to the personal computer, so that the personal computer can select the channel to which the cable demodulator is tuned such that multiple data channels can be used.
