The ADV7181C is a high quality, single-chip, multiformat
video decoder and graphics digitizer. This multiformat decoder
supports the conversion of PAL, NTSC, and SECAM standards
in the form of composite or S-Video into a digital ITU-R BT.656
format. The ADV7181C also supports the decoding of a com-
ponent RGB/YPrPb video signal into a digital YCrCb or RGB
DDR pixel output stream. The support for component video
includes standards such as 525i, 625i, 525p, 625p, 720p, 1080i,
and many other HD and SMPTE standards. Graphics digitization
is also supported by the ADV7181C; it is capable of digitizing
RGB graphics signals from VGA to SXGA rates and converting
them into a digital DDR RGB or YCrCb pixel output stream.
SCART and overlay functionality are enabled by the ability of
the ADV7181C to process simultaneously CVBS and standard
definition RGB signals. The mixing of these signals is controlled
by the fast blank pin.
The ADV7181C contains two main processing sections. The
first section is the standard definition processor (SDP), which
processes all PAL, NTSC, and SECAM signal types. The second
section is the component processor (CP), which processes YPrPb
and RGB component formats, including RGB graphics.
