Many thanks for your reply.

The Bt878 is a single solution for a PCI card. I really need 8 bit
data with embedded SAV and EAV codes etc. Sorry I should have been
more specific.

I think there is a conflict here. By requiring SAV & EAV codes you are
implying that you need CCIR656 coding. Unfortunately CCIR656 is an
extension of CCIR601 which specifies 720 pixels per active line and
13.5MHz sampling. Can't have both SAV/EAV and 768 pixels.


Strictly speaking you are correct. However in practice the SAV/EAV codes
are generally available in non CCIR656 formats from many IC vendors. It is
something bearing in mind that it's a not a "standard".
