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.
