Abstract:
1. An apparatus comprising: a housing to connect at a signal transmission line of a CATV system at a premise of a user downstream of a first signal transmission line configured to be used by a plurality of users; a modem to receive downstream information and to receive upstream information; a conditioning control circuit to modify a signal on said signal transmission line transmitted between the premise and the first signal transmission line wherein the conditioning control circuit is a downstream bandwidth output level and/or output level tilt compensation device comprising: a tuner configured to scan a downstream bandwidth to identify at least one low band channel and at least one high band channel; a channel analyzer configured to determine a format of each of the low band channel and the high band channel; a signal measurement device configured to measure a low band signal strength of the low band channel and a high band signal strength of the high band channel; an offset circuit configured to perform at least two of (i) add a first offset value to the low band signal strength when the low band channel is a digital format, (ii) subtract a second offset value from the low band signal strength when the low band channel is an analog format, (iii) add a the first offset value to the high band signal strength when the high band channel is the digital format, and (iv) subtract the second offset value from the high band signal strength when the high band channel is the analog format; a microprocessor configured to compare the low band signal strength and the high band signal strength, including any offset values, to a predetermined signal strength loss curve; a variable output level compensation device; and a variable slope adjusting circuit.
