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 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, 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 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 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.

Note that the ADV7181C has unique software and hardware

configuration requirements. See Page 19 of this data sheet for

more information.
