Square-division versus two-sample interleave (2SI)

Or in AVP terminology, Quad vs Interleaving

Quad (Square Division)

Quad (Square Division) is the way we started our AVP H.264 contribution. The 4K signal is presented as 4xHD-SDI (up to p30) or 4x3G-SDI (up to p60). Each input is a quarter of the image (quadrant).
