Abstract
A cable television (CATV) entry adapter connects to a CATV network and serves as a hub in an In-Home Entertainment (IHE) network. IHE signals may be communicated between passive and active ports of an embodiment of the entry adapter through a pair of directional couplers which allow an IHE-enabled embedded multimedia terminal device (eMTA) at the passive port to communicate with multimedia devices of the IHE network connected to the active ports. An IHE frequency rejection filter is used in some embodiments to confine IHE signal to a single subscriber premise. In some embodiments a bidirectional IHE bandpass filter is used to enable IHE signals to pass between the passive and active ports of the CATV entry adapter.
