Abstract

A system is described that consists of a variable modulation unicast system that utilizes multiple modulation schemes in a cable network for unicast applications and is capable of assigning users to different channels of differing modulation schemes in the network based on a feedback signal received in response to a transmitted probe signal. The system may also, in response to the feedback signal from a remote device in the network, assign a channel from a plurality of channels having differing carrier frequencies and modulation schemes to the remote device and may also modify the carrier frequencies of the channels.

First claim

The invention claimed is:

1. A variable modulation unicast system (“VMUS”) for selecting a channel from a plurality channels the VMUS comprising:
a transmitter capable of transmitting a first signal to a plurality of remote devices, wherein the first signal utilizes a first modulation scheme;
a receiver capable of receiving a plurality of feedback signals from the plurality of remote devices in response to transmitting the first signal, wherein the feedback signals include ident…
