A method for generating a representation of a particular signal among
video signals representing a display, the signals including a first
component having a first bandwidth and a second component having a
smaller second bandwidth, includes the steps of: (a) measuring first
samples of the first component outside the second bandwidth for an
interval in each signal; (b)measuring second samples of the second
component inside the second bandwidth for the interval; (c) establishing
factors based upon first samples; (d) establishing filter modes based
upon second samples; (e) establishing a correlation between factors and
filter modes; (f) filtering the signals using a selected filter mode; (g)
identifying a selected factor according to the correlation for the
selected filter mode; (h) employing the selected factor for weighted
mixing of the samples to generate the representation for the time
interval; and (g) repeating steps (a) through (h) until the
representation is completed.
