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.
APPLICATIONS
Automotive entertainment
HDTVs
LCD/DLP® projectors
HDTV STBs with PVR
DVD recorders with progressive scan input support
AVR receivers
