<p>In accordance with an embodiment of the present invention, a home controller receives signals from the cable television system and utilizes a cable demodulator tuned to the RF frequency of the channel which carries the data information. The cable demodulator demodulates the RF encoded signals into conventional baseband digital form which are transmitted to a packet receiver which decodes packets addressed to individual users. If a packet is addressed to the user, the packet receiver transmits the corresponding data such as by an ETHERNET transceiver to the user's personal computer. A communication controller may be utilized to provide an interface between the personal computer and the cable demodulator, thereby enabling the personal computer to select the channel to which the cable demodulator is tuned, in order to permit multiple data channels to be utilized.</p> |
