GENERAL DESCRIPTION
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 component
RGB/YPrPb video signal into a digital YCrCb or RGB 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 XGA 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.
Note that the ADV7181C has unique software and hardware
configuration requirements. See Pag
e 19 of this data sheet for
more information.
