Input SDI
Selects the input link configuration. Choose from the following:
Auto -
Automatically selects the link configuration based on the detected input
video parameters. To the right of the drop-down menu, the status display
reflects the current Input SDI behavior.
In order for "Auto" to select Quad Link (SDI 1-4), all four inputs must match in
terms of data rate, link mapping, raster, frame rate, scan type, sampling, bit
depth, and pixel mapping.
Single Link (SDI 1) -
Select this option if you have a Single Link UltraHD/4K signal
coming in through SDI In 1.
Single Link (SDI 2) -
Select this option if you have a Single Link UltraHD/4K signal
coming in through SDI In 2.
Single Link (SDI 3) -
Select this option if you have a Single Link UltraHD/4K signal
coming in through SDI In 3.
Single Link (SDI 4) -
Select this option if you have a Single Link UltraHD/4K signal
coming in through SDI In 4.
Quad Link (SDI 1-
4) - Select this option if you have a Quad Link UltraHD/4K signal
coming in through SDI In 1-4.
Input Mapping
NOTE: Input pixel mapping applies only to 4K/UltraHD signals being transported on
Quad Link 4 x 3G inputs, as 6G and 12G SDI are always Two Sample Interleave
(2SI), and Quad Link 1.5G SDI is always Square Division (Quadrant).
For 4K/UltraHD signals using Quad Link 3Gbps transport, the Video Payload
Identifier (VPID) embedded in each link indicates whether the pixel mapping is
2SI or not. If 2SI is not indicated, the OG-12GM assumes that the input signal is
mapped Square Division (Quadrant). Note that there are no specific VPID bits to
indicate Square Division (Quadrant).
