GENERAL DESCRIPTION
The ADV7181D 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 ADV7181D also supports the decoding of a component
RGB/YPrPb video signal into a digital YCrCb or RGB pixel
output stream. 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 ADV7181D; 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 ADV7181D to simultaneously process CVBS
and standard definition RGB signals. The mixing of these signals
is controlled by the fast blank (FB) pin.
The ADV7181D 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.
The ADV7181D has unique software and hardware configuration
requirements. For more information, see the Typical Connection
Diagram section.
