Passive Multi-Port Entry Adapter and Method for Preserving Downstream CATV Signal Strength within In-Home Network
First Claim
1. A cable television (CATV) entry adapter for conducting downstream and upstream CATV signals between a CATV network and at a least one subscriber device at subscriber premises and for conducting in-home network signals between multiple subscriber devices at the subscriber premises connected in an in-home network, the CATV signals occupying a CATV frequency band which is different from an in-home network frequency band occupied by the in-home network signals, the in-home network including a network interface connected to each subscriber device by which to generate and communicate the network signals between the subscriber devices in the in-home network, the CATV entry adapter comprising:
- a CATV entry port for connection to the CATV network;
a plurality of network ports each for connection to the network interface to which each subscriber device is connected;
a signal splitter having an input terminal and two output terminals, the signal splitter operatively splitting a signal received at its input terminal into reduced-power copies of the input signal supplied at each of its output terminals, the signal splitter also communicating signals received at each output terminal to the input terminal and to each other output terminal, each output terminal connecting to one of the network ports; and
an in-home network frequency band rejection device connected between the CATV entry port and the input port of the signal splitter, the in-home network frequency band rejection device substantially blocking transmission of the in-home network signals therethrough to the CATV entry port and the CATV network.

Abstract
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.

16. An in-home network for distributing multimedia content to subscriber devices, the multimedia content obtained from CATV signals communicated over a CATV network and obtained from a subscriber device connected to the in-home network, the in-home network comprising:
-
a CATV entry adapter having a CATV entry port and a plurality of network ports, the CATV entry port connected to a CATV network for receiving multimedia content from CATV signals communicated over the CATV network; a plurality of in-home network interfaces, each of the network interfaces connected to a different one of the plurality of network ports; each of the network interfaces communicate multimedia content to the subscriber devices to which each network interface is connected; all of the network interfaces communicate multimedia content between one another in network signals communicated between the network interfaces; at least one of the network interfaces sends and receives CATV signals and communicates the multimedia content contained in the CATV signals to the subscriber device to which the one network interface is connected and communicates the multimedia content obtained from the CATV signals in network signals communicated through the CATV entry adapter to another network interface; each of the network interfaces communicates multimedia content obtained from a subscriber device connected to that network interface in network signals communicated through the CATV entry adapter to another network interface; and
wherein;the network signals are located within a network frequency band which is different from a CATV frequency band within which the CATV signals are located. - View Dependent Claims (17, 18, 19, 20)

21. A method of communicating information contained in downstream and upstream CATV signals between a CATV network and at a least one subscriber device at a subscriber premises and contained in network signals conducted between multiple subscriber devices at the subscriber premises connected in an in-home network, comprising:
-
connecting a CATV entry adapter to receive and transmit CATV signals from and to the CATV network, respectively; connecting in-home network interfaces to each subscriber device to form the in-home network among the subscriber devices to which network interfaces are attached; connecting the CATV entry adapter as a hub in the in-home network to pass network signals between network interfaces; confining the network signals to an in-home network frequency band; confining the CATV signals to a CATV network frequency band which is different from the in-home network frequency band; connecting the CATV adapter to at least one network interface to receive and transmit CATV signals supplied from and to the CATV entry adapter; and preventing transmission of the network signals within the CATV entry adapter onto the CATV network. - View Dependent Claims (22, 23, 24, 25)
