The ADV7181C series high quality Video Decoder and Graphics Digitizer. This multi-format 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. 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.
