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 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.
