Where can I get documentation regarding AHD support of ADV7181D?
There is not much on the datasheet.
Most of our video decoders can support analog HD signal -720p60 .
Please refer below product page for more video decoders and their respective manuals.,
In CVBS you cannot support HD format.Basically here video information are encoded on one channel ,its not capable for HD format support. In composite interface(CVBS) which carries the SD video (typically at 480i or 576i resolution) as a single channel..It is simply conveys as SD video for the standard definition television signal.
But even other higher quality analog interface like component video which has three channels (YPbPr).it can support ED/HD standard as well. Here it can use CP to process all component video standards include 525i, 625i, 525p, 625p, 720p, 1080i, 1080p, 1250i, VGA up to UXGA at 60 Hz.
So in component video interface you can support the AHD standard in our decoders.
