DIGITAL NOISE REDUCTION (DNR) AND LUMA
PEAKING FILTER
Digital noise reduction is based on the assumption that high
frequency signals with low amplitude are probably noise and
that, therefore, their removal improves picture quality. The
following are the two DNR blocks in the ADV7180: the DNR1
block before the luma peaking filter and the DNR2 block after
the luma peaking filter, as shown in Figure 32.

DNR_TH[7:0], DNR Noise Threshold, Address 0x50[7:0]
The DNR1 block is positioned before the luma peaking block.
The DNR_TH[7:0] value is an unsigned, 8-bit number used to
determine the maximum edge that is interpreted as noise and,
therefore, blanked from the luma data. Programming a large
value into DNR_TH[7:0] causes the DNR block to interpret
even large transients as noise and remove them. As a result, the
effect on the video data is more visible. Programming a small
value causes only small transients to be seen as noise and to be
removed.

PEAKING_GAIN[7:0], Luma Peaking Gain,
Address 0xFB[7:0]
This filter can be manually enabled. The user can select to boost
or to attenuate the mid region of the Y spectrum around 3 MHz.
The peaking filter can visually improve the picture by showing
more definition on the picture details that contain frequency
components around 3 MHz. The default value on this register
passes through the luma data unaltered. A lower value attenuates
the signal, and a higher value gains the luma signal. A plot of
the responses of the filter is shown in Figure 33.

DNR_TH2[7:0], DNR Noise Threshold 2,
Address 0xFC[7:0]
The DNR2 block is positioned after the luma peaking block
and, therefore, affects the gained luma signal. It operates in the
same way as the DNR1 block, but there is an independent
threshold control, DNR_TH2[7:0], for this block. This value is
an unsigned, 8-bit number used to determine the maximum
edge that is interpreted as noise and, therefore, blanked from
the luma data. Programming a large value into DNR_TH2[7:0]
causes the DNR block to interpret even large transients as noise
and remove them. As a result, the effect on the video data is more
visible. Programming a small value causes only small transients
to be seen as noise and to be removed.
