Multiple-room signal distribution system

In a transmission system in which digital television signals are transmitted to a plurality of user locations, wherein each of said user locations includes a plurality of service areas therein, a television signal distribution system at one or more of said user locations and comprising:

• a central unit having a primary television signal input port that received primary digital television signals, said primary digital television signals comprising a plurality of primary digital television signal components;
• said central unit further having at least one output port that outputs to a distribution network selected ones of said plurality of primary digital television signal components for distribution to each of the plurality of service areas;
• and
• said central unit having signal processing circuitry that receives said primary digital television signal, along with a plurality of coded user selection signals, each including a coded portion;
• said signal processing circuitry further comprises a remote interface circuit that receives said coded portion of said coded user selection signals;
• said remote interface circuit comprising a plurality of demodulators;
• said remote interface circuit further comprising a plurality of remote code select switches coupled to said demodulators wherein said remote code select switches restrict the operation of said demodulators;
• and
• wherein said demodulators selectively distribute a decoded signal to said decoder modules and
• said signal processing circuitry processing said primary digital television signal based on said user selection signals, along a plurality of parallel and independent signal paths to independently and in parallel provide any one of said primary digital television signal components to said at least one output port, said signal processing circuitry comprises decoder modules for each of said plurality of parallel and independent signal paths, said decoder modules independently and in parallel decoding said primary digital television signal to provide any one of said primary digital television signal components to said at least one output port;
• and
• wherein said user selection signals comprise a user selection component that identifies one of the plurality of primary digital television signal components and wherein the coded portions of said user selection signals identify one of said plurality of parallel and independent signal paths, and
• wherein said remote interface circuit is coupled to a power signal distribution network and is adapted to retrieve said user selection signals from said power signal distribution network.
