GENERAL DESCRIPTION
The ADV7403 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 ADV7403 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, 1250i, and many
other HD and SMPTE standards. Graphic digitization is also
supported by the ADV7403; it is capable of digitizing RGB
graphics signals from VGA to SXGA rates and converting them
into a digital RGB or YCrCb pixel output stream. SCART and
overlay functionality are enabled by the ability of the ADV7403
to simultaneously process CVBS and standard definition RGB
signals. The fast blank pin controls the mixing of these signals.
The ADV7403 contains two main processing sections. The first
is the standard definition processor (SDP), which processes all
PAL, NTSC, and SECAM signal types, and the second is the
component processor (CP), which processes YPrPb and RGB
component formats, including RGB graphics. For additional
descriptions of the features of the ADV7403, see the Functional
Overview and the Theory of Operation sections.
