 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).

-In Square Division QUAD mode
+In Square Division QUAD mode, the picture is split in to four quadrants, each quadrant containg a quarter of the image.

+Each quadrant comprises exactly 1/4 of the UHD Image (so a 1920x1080 HD image)

+\\
+For 2SI mode, each quadrant contains a quarter of the picture information, but as a fully decodable HD image.
