Patent ID: 7324167

Claim:
A transmission line filter system, comprising: (a) a first filter having an input and an output adapted to compensate for the characteristics of a first length of twisted-pair wire; (b) a first bypass path having an input and an output for bypassing said first filter; (c) a second filter having an input and an output adapted to compensate for the characteristics of a second length of twisted-pair wire; (d) a second bypass path having an input and an output for bypassing said first filter; (e) a third filter having an input and an output adapted to compensate for the characteristics of a third length of twisted-pair wire; (f) a third bypass path having an input and an output for bypassing said first filter; (g) a coupling device for coupling an input high resolution video signal; (h) a first input switch for connecting said coupling device to the input of said first filter or said first bypass path; (i) a first output switch coupling the output of said first filter, when said first input switch is connecting said coupling device to the input of said first filter, or coupling said first bypass path when said first input switch is connecting said coupling device to said first bypass path; (j) a second input switch for connecting said first output switch to the input of said second filter or said second bypass path; (k) a second output switch coupling the output of said second filter, when said second input switch is connecting said first output switch to the input of said second filter, or coupling said second bypass path when said second input switch is connecting said first output switch to said second bypass path; (l) a third input switch for connecting said second output switch to the input of said third filter or said third bypass path; (m) a third output switch coupling the output of said third filter, when said third input switch is connecting said second output switch to the input of said third filter, or coupling said third bypass path when said third input switch is connecting said second output switch to said third bypass path; and (n) an output coupling line coupled to receive the output from said third output switch.
