1. An in-home entertainment network conditioning device for use with a coaxial device, the conditioning device comprising:

  • an input node, wherein;

    the input node conducts community access television (CATV) signals and in-home entertainment signals, the community access television signals comprising;

    downstream signals in a first frequency range; and

    upstream signals in a second frequency range that is different from the first frequency range;

    andthe in-home entertainment signals comprise signals in a third frequency range that is different from the first frequency range and the second frequency range;

    a first signal path branched from the input node, wherein the first signal path comprises a low-pass filter, wherein the low-pass filter conducts the upstream and downstream community access television signals and wherein the low-pass filter rejects the in-home entertainment signals;

    a second signal path branched from the input node and in parallel electrical communication with the first signal path;

    andan output node joining the first signal path and the second signal path;

    wherein the second signal path comprises;

    a first high-pass filter in series electrical connection with a signal conditioning circuit, wherein the first high-pass filter conducts the in-home entertainment signals and rejects the upstream and downstream community access television signals, and wherein the first high-pass filter is connected electrically between the input node and the signal conditioning circuit, and wherein the signal conditioning circuit attenuates the in-home entertainment signals and passes the upstream and downstream CATV signals without attenuation in response to being coupled to the coaxial device;

    anda second high-pass filter in series electrical connection with the signal conditioning circuit, wherein the second high-pass filter conducts the in-home entertainment signals and rejects the upstream and downstream community access television signals, and wherein the second high-pass filter is connected electrically between the signal conditioning circuit and the output node.
