The ADV7800 is a high quality, single-chip, multiformat 3D comb filter, video decoder, and graphics digitizer. This multiformat 3D comb filter decoder supports the conversion of PAL, NTSC, and SECAM standards in the form of a composite or an S-Video into a digital ITU-R BT.656 format. The ADV7800 also supports the decoding of a component RGB/YPbPr 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, 1080p, and many other HD and SMPTE standards. Graphics digitization is supported by the ADV7800; it is capable of digitizing RGB graphics signals from VGA to SXGA rates and converting them into a digital RGB or YCrCb pixel output stream. SCART and overlay functionality are enabled by the ability of the ADV7800 to simultaneously process CVBS and standard definition RGB signals.
The ADV7800 contains two main processing sections. The first section is the standard definition processor (SDP), which processes all PAL, NTSC, SECAM, and component (up to 525p/625p) signal types. The second section is the component processor (CP), which processes YPrPb and RGB component formats, including RGB graphics.
