1. A customer premises system in which:

  • the terms;

    a digital data packet is;

    a container of data defined by boundaries set according to a protocol;

    communicate is;

    to transmit digital data packets bi-directionally, with a hand-shaking mechanism for each digital data packet;

    broadcast is;

    to transmit digital data packets in one direction, with no hand-shaking mechanism for each digital data packet;

    including;

    a wireless multimedia center (WMC) for reception on said premises from one or more signal sources and for distribution of segments of signals from said signal sources through the wireless multimedia centerto a plurality of end units, in which;

    the signals include video and/or audio signals (hereinafter video) and/or broadband communication data;

    the wireless multimedia center receives all the signals and distributes segments of said signals via a transmitter;

    the video signals are broadcast by orthogonal frequency division multiplexing (OFDM) in which all signals are added together and summed as an orthogonal array having dimensions of time, frequency and amplitude, to transmit spread spectrum multiplexed signals, in which each pulse including said signals has sufficiently long individual pulse widths to defeat multi-path, reflection and absorption phase induced losses;

    and;

    the video signals are broadcast from the wireless multimedia center via one or more separate and dedicated RF channels to one or more end units;

    andoptionally, the end units communicate simultaneously with the wireless multimedia center, via a separate bi-directional wideband data pipe (WDP) which provides, as demanded, control for the video channels, data transfer, or plain old telephone service, wherein said wireless multimedia center controls which segments of which signals are distributed to each end unit;

    the video signals are broadcast independently without the presence of communication signals and/or are broadcast simultaneously with the communication signals.
