COMPONENT PROCESSOR (CP)
The component processor section is capable of decoding and
digitizing a wide range of component video formats in any color
space. Component video standards supported by the CP are
525i, 625i, 525p, 625p, 720p, 1080i, 1080p, 1250i, VGA up to
UXGA at 60 Hz, and many other standards.
The CP section of the ADV7441A contains an AGC block. This
block is followed by a digital clamp circuit that ensures that the
video signal is clamped to the correct blanking level. Automatic
adjustments within the CP include gain (contrast) and offset
(brightness); however, manual adjustment controls are also
supported. If no embedded synchronization is present, the
video gain can be set manually.
A fully programmable any-to-any 3 × 3 color-space converter is
placed before the CP section. This enables YPrPb-to-RGB and
RGB-to-YCrCb conversions. Many other standards of color
space can be implemented using the color-space converter.
A second fully programmable any-to-any 3 × 3 color space
converter is placed in the back end of the CP core. This color
space converter features advanced color controls such as
contrast, saturation, brightness, and hue controls.

The output section of the CP is highly flexible. It can be configured
in single data rate mode (SDR) with one data packet per clock
cycle. In SDR mode, a 16-/20-bit 4:2:2 or 24-/30-bit 4:4:4 output
is possible. In these modes, HS/CS, VS/FIELD, and DE/FIELD
(where applicable) timing reference signals are provided.
The CP section contains circuitry to enable the detection of
Macrovision-encoded YPrPb signals for 525i, 625i, 525p, and
625p. It is designed to be fully robust when decoding these
types of signals.
VBI DATA PROCESSOR
VBI extraction of CGMS data is performed by the VBI data
processor (VDP) section of the AD7441A for interlaced,
progressive, and high definition scanning rates. The data
extracted is read back over the I
