4K video can be transported by mapping it into four segments (quadrants) to be moved via 4x 3G SDI lines.
Typically only one of the SDI lines will carry up to 16ch embedded audio. In case of low latency audio control no further manipulation of the non-audio SDI streams is required (Fig.1).
In case of audio control with latency of more then 20 milliseconds, a video delay for A/V time shift compensation should be enabled.
In this case all other non-audio 3G SDI streams needs to be delayed the same way (Fig. 2).
Jünger Audio SDI solutions are proofed to perform well with mapped 4K video signals as shown below:
