Local area network above cable television methods and devices
First Claim
1. A communication apparatus for implementing a broadband communication network using a cable-based television network installed in a building, wherein the cable-based television network includes a video distribution device coupled to one or more coaxial cables, and wherein each coaxial cable can carry one or more downstream television broadcast signals and one or more upstream television control signals, the device comprising:
- a communications modem configured to transmit first communication signals over the one or more coaxial cables using a first allocated spectrum designed to avoid contention with ongoing upstream television control signals.

Abstract
A method and apparatus for modifying a cable network to create a local area network is disclosed. By employing a communications modem configured to transmit first communication signals over one or more coaxial cables using a first allocated spectrum designed to avoid contention with ongoing upstream television control signals, an infrastructure capable of carrying demand cable television and LAN signals can be created.

18. A method for communicating over a demand cable television network, comprising:
-
transmitting a broadband communication signal having embedded information onto the cable television network, the embedded information being derived from a signal provided by an Internet Service Provider (ISP);
wherein the broadband communication signal is compliant with a local area network protocol, and where transmitting the broadband communication signal is designed to have no appreciable affect on cable television control signals residing on the cable network. - View Dependent Claims (19, 20)

22. A system for adapting a cable television network that carries both video and video control signals to provide a local area network, wherein the cable television network includes a video access device for providing video services to a plurality of client access points, and wherein the video access device is coupled to the client access points by plurality of coaxial cables and one or more video splitters, the system comprising:
-
a local area network gateway configured to receive upstream signals transmitted from a first client access point, wherein the local area network gateway is coupled to the first client access point via at least one cable and one video splitter; and
wherein the local area network gateway is further configured to retransmit information received in the upstream signals downstream to a second client access point, wherein the local area network gateway is coupled to the second client access point via at least one cable and one video splitter. - View Dependent Claims (23, 24, 25, 26, 27)

28. A method for communicating over a cable television network that carries both video and video control signals, wherein the cable television network includes a video access device for providing video services to a plurality of client access points in the cable television network, and wherein the video access device is coupled to the client access points by plurality of coaxial cables and one or more video splitters, the method comprising:
-
receiving an upstream signal transmitted from a first client access point via at least a first cable and a first video splitter; and
transmitting information receive in the upstream signal downstream to a second client access point via at least a second cable and a second video splitter;
wherein either the first cable or the first video splitter is not in the path to the second client access point - View Dependent Claims (29, 30, 31, 32, 33, 34)
