1. An entry adapter for controlling upstream and downstream communications between a cable television (CATV) network and a client multimedia over coaxial alliance (MoCA) network, without diminishing downstream CATV signal strength within the client MoCA network to an extent that disrupts CATV signal communications within the client MoCA network, comprising:

  • a plurality of ports configured to allow downstream and upstream CATV signals to be distributed between a CATV network and a client MoCA network, wherein the plurality of network ports comprises an entry port configured to communicate with the CATV network, a primary network port, and secondary network ports;

    two-way, high/low frequency band isolation and limited distribution means for allowing downstream and upstream CATV network signals to communicate with the primary port, blocking client network signals from being communicated upstream to the CATV network, and splitting a MoCA network signal into a plurality of reduced signal-strength network signal copies to be communicated to the secondary ports;

    wherein the two-way, high/low frequency band isolation and limited distribution means is configured to isolate network signals into a high frequency band range and a low frequency band range so as to allow downstream and upstream low frequency band CATV network signals to communicate with the primary port while blocking high frequency band client network signals from being communicated upstream to the CATV network, and while communicating the high frequency band client network signals between the primary port and the secondary ports;

    wherein the two-way, high/low frequency band isolation and limited distribution means is configured to transmit the downstream CATV signal to the primary port without splitting the downstream CATV signal more than once between the entry port and the primary port, so as to prevent disruption of signal communication between the CATV network and the client MoCA network;

    wherein the client MoCA network signals are in the high frequency band range, and not in the low frequency band range;

    wherein the downstream and upstream CATV network signals are in the low frequency band range, and not in the high frequency band range; and

    wherein the entry adapter is configured to permit a plurality of client MoCA devices to communicate with each other to deliver multimedia content using a MoCA communication protocol over the client MoCA network.
