Passive multi-port entry adapter and method for preserving downstream CATV signal strength within in-home network

摘要

A cable television (CATV) entry adapter interfaces to a CATV network and serves as a hub in an in-home network for passively communicating multimedia content or information from the CATV network and between subscriber devices connected to the ports of the CATV entry adapter, using CATV signals in a CATV frequency band and network signals in a different in-home network band.

主权项

1. An entry adapter for delivering downstream and upstream signals between a network and one or more subscriber devices, the entry adapter comprising:
an entry port for connection to the network; one or more network ports for connection to the one or more subscriber devices; a signal splitter comprising an input terminal and at least two output terminals; and a frequency band rejection device coupled between the entry port and the input terminal of the signal splitter,
wherein the frequency band rejection device is configured to allow the upstream and downstream signals from the network, in a first frequency band, to pass through to at least one of the one or more subscriber devices andwherein the frequency band rejection device is configured to block, from entering the network, signals communicated between the one or more subscriber devices in a second frequency band.
