CHROMA FILTER
Data from the digital fine clamp block is processed by three sets
of filters. The data format at this point is CVBS for CVBS inputs,
chroma only for Y/C, or U/V interleaved for YPrPb input
formats.
Chroma Antialias Filter (CAA). The ADV7183B over-
samples the CVBS by a factor of 2 and the Chroma/PrPb
by a factor of 4. A decimating filter (CAA) is used to
preserve the active video band and to remove any out-of-
band components. The CAA filter has a fixed response.
Chroma Shaping Filters (CSH). The shaping filter block
(CSH) can be programmed to perform a variety of low-
pass responses. It can be used to selectively reduce the
bandwidth of the chroma signal for scaling or
compression.
Digital Resampling Filter. This block is used to allow
dynamic resampling of the video signal to alter parameters
such as the time base of a line of video. Fundamentally, the
resampler is a set of low-pass filters. The actual response is
chosen by the system without user intervention.
The plots in
183H
Figure 16 show the overall response of all filters
together.
