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.
