Preliminary Data Sheet
signal the delay of the feed back path can be either a field delay (DTNRON=0) or a frame delay
(DTNRON=1) (block diagram of noise reduction).
Equation for temporal noise reduction (luminance signal)
Equation for temporal noise reduction (chrominance signal)
The next figure shows the motion detector in more detail. Temporal noise reduction can be switched
off by NRON (NRON=0). The parameter TNRFIY/C switches between a fixed noise reduction K-
factor TNRVAY/C (TNRFIY/C=0) or a motion adaptive noise reduction K-factor (TNRFIY/C=1).
Block diagram of motion detector
In case of adaptive noise reduction the K-factor depends on the detected “Motion” (see figure
above). The “Motion”-Ky/Kuv characteristic curve (LUT) is fixed inside the SDA 9400, but the
characteristic curve can be changed by two parameters: TNRHOY/C and TNRKOY/C. TNRHOY/C
shifts the curve horizontally and TNRKOY/C shifts the curve vertically. For a fixed characteristic
curve, the sensitivity of the motion detector is adjustable by TNRCLY/C.
