Patent ID: 7613252

Claim:
A method of installation of a receiver to receive broadcast data transmitted from a broadcaster for use to generate audio and/or video at each receiver broadcast continuously to a plurality of locations including the location of the receiver, said method comprising; measuring the power level of a broadcast data signal at two predetermined spaced points on the signal band transmitted from a broadcaster by measuring the content of automatic gain control converters having one switch filter relating to said broadcast data signal within the receiver, a portion of the broadcast data signal which content is measured is the data used to generate the audio and/or video at the receiver locations for display at the receiver location for the purpose of viewing the display; selectively operating the switch filter on said broadcast data signal to allow the correction of amplitude variations with frequency, the selective operation of the filter dependent upon and responsive to the power level measurements obtained from the signal transmitted from the broadcaster without having knowledge of a training signal cable slope; and utilizing, if required, a relative signal strength for installation of said broadcast data receiver instead of an absolute signal strength.
