GENERAL DESCRIPTION
The ADV7401 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 ADV7401 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,
1250i, and many other HD and SMPTE standards. Graphic
digitization is also supported by the ADV7401; 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
ADV7401’s ability to simultaneously process CVBS and
standard definition RGB signals. The mixing of these signals is
controlled by the fast blank pin.
The ADV7401 contains two main processing sections. The first
is the standard definition processor (SDP), which processes all
PAL, NTSC, and SECAM signal types. The second is the
component processor (CP), which processes YPrPb and RGB
component formats, including RGB graphics. For more specific
descriptions of the ADV7401 features, see the Detailed
Functionality and Detailed Description sections.
