DOWNSTREAM BANDWIDTH CONDITIONING DEVICE
First Claim
1. A downstream bandwidth conditioning device that can be inserted into a transmission line of a CATV system on or proximate to a premise of a user, the device comprising:
- a forward path extending at least a portion of a distance between a supplier side connector and user side connector;
a coupler connected within the forward path, the coupler providing a secondary path;
a tuner being connected to the coupler and being tunable based on an input from a microprocessor, the tuner providing a tuner output of a selected channel, the selected channel being at least one of a high frequency channel and a low frequency channel;
a channel analyzer being connected to an output of the tuner, the channel analyzer providing the microprocessor with a modulation output, the modulation output differing when the selected channel is an analog modulation versus when the selected channel is a digital modulation;
a slope adjustment circuit being connected within the forward path between the coupler and the supplier side connector, the slope adjustment device being adjustable based on an slope control output provided by the microprocessor; and
an output compensation circuit electrically connected within the forward signal path between the coupler and the supplier side connector, the output compensation device being adjustable based on a level control output from the microprocessor.

Abstract
A downstream bandwidth conditioning device includes a forward path. A coupler is connected within the forward path providing a secondary path. A tuner connected to the coupler is tunable based on an input from a microprocessor. The tuner provides a tuner output of a selected channel, the selected channel being at least one high frequency channel and one low frequency channel. A channel analyzer connected to an output of the tuner provides the microprocessor with a modulation output that differs when the selected channel is an analog modulation versus a digital modulation. A slope adjustment circuit connected within the forward path between the coupler and the supplier side connector is adjustable based on an slope control output provided by the microprocessor. An output compensation circuit connected within the forward signal path between the coupler and the supplier side connector is adjustable based on a level control output from the microprocessor.

16. A method for conditioning a downstream bandwidth on or proximate to a premise of a user of CATV services, the method comprising:
Initiating a first mode, the first mode comprising; tuning to an initial high frequency channel from a downstream bandwidth; obtaining a high channel modulation and a high channel level from the initial high frequency channel; tuning to an initial low frequency channel from the downstream bandwidth; obtaining a low channel modulation and a low channel level from the initial low frequency channel; providing an amount of level adjustment of the downstream bandwidth; and providing an amount of slope adjustment of the downstream bandwidth. - View Dependent Claims (17, 18, 19, 20, 21, 22)
