Using Io 4K Plus for UltraHD/4K
4K/UltraHD Transport Modes
The 4K and UltraHD SDI formats can use different transport modes, associated
with the number of links used to transport the signal, the data rates involved, and
the way the image data is organized.
Io 4K Plus supports both Quadrant and Two Sample Interleave (2SI) transport
standards. Many different combinations of modes and data organization exist.
In 4K mode, single link transport is available as either 12G or 6G (which are both
2SI). Whether the video is auto-sensed as 12G vs. 6G is dependent on the data rate
of the incoming or outgoing signal. For example, 4K p30 at 8bit 4:2:0 requires 6G
only.
