Figure 20. Block Diagram of the Video Processor
Figure 20 shows a block diagram of the ADV7180 video processor.
The ADV7180 can handle standard definition video in CVBS,
Y/C, and YPrPb formats. It can be divided into a luminance and
chrominance path. If the input video is of a composite type
(CVBS), both processing paths are fed with the CVBS input.
SD LUMA PATH
The input signal is processed by the following blocks:
Luma digital fine clamp. This block uses a high precision
algorithm to clamp the video signal.
Luma filter. This block contains a luma decimation filter
(YAA) with a fixed response and some shaping filters
(YSH) that have selectable responses.
Luma gain control. The automatic gain control (AGC) can
operate on a variety of different modes, including gain based
on the depth of the horizontal sync pulse, peak white mode,
and fixed manual gain.
Luma resample. To correct for line length errors as well as
dynamic line length changes, the data is digitally resampled.
Luma 2D comb. The 2D comb filter provides Y/C separation.
AV code insertion. At this point, the decoded luma (Y) signal
is merged with the retrieved chroma values. AV codes can
be inserted (as per ITU-R BT.656).
SD CHROMA PATH
The input signal is processed by the following blocks:
Chroma digital fine clamp. This block uses a high precision
algorithm to clamp the video signal.
Chroma demodulation. This block employs a color
subcarrier (fSC) recovery unit to regenerate the color
subcarrier for any modulated chroma scheme. The
demodulation block then performs an AM demodulation
for PAL and NTSC, and an FM demodulation for SECAM.
Chroma filter. This block contains a chroma decimation
filter (CAA) with a fixed response and some shaping filters
(CSH) that have selectable responses.
Chroma gain control. AGC can operate on several different
modes, including gain based on the color subcarrier
amplitude, gain based on the depth of the horizontal sync
pulse on the luma channel, or fixed manual gain.
Chroma resample. The chroma data is digitally resampled
to keep it perfectly aligned with the luma data. The
resampling is done to correct for static and dynamic line
length errors of the incoming video signal.
Chroma 2D comb. The 2D, five line, superadaptive comb
filter provides high quality Y/C separation in case the input
signal is CVBS.
AV code insertion. At this point, the demodulated chroma
(Cr and Cb) signal is merged with the retrieved luma values.
AV codes can be inserted (as per ITU-R BT.656).
