I dread to think of the Native data rate for 4320 at 120fps uncompressed is.
The baseband video connector looks like a BNC but has 24 fibre cores (or is it 32?)... It's based on HD streams forming 4K streams that in turn form 8K streams.
Back of envelope calculation :
7680 x 4320 x 120 at 4:2:2 12 bit (=24 bits per pixel) suggests 95Gb/s ...
That's around 10 times that of "4K" 3840x2160 at 60fps with 4:2:2 10-bit - which is around 10Gbs, or around 100 times that of our current HD standard of 1920x1080 25fps interlaced 4:2:2 10 bit which is around 1Gbs.
That's only considering active video and ignoring any blanking or audio.
Of course IP interconnects will also be a reality - but they will probably include some mezzanine compression or handle the 8K stream as 4K streams (or both) to get the bitrate down to something that will fit in 100GbE or lower...
(Europe is lucky that 4K at 50fps just squeaks into 10GbE without compression, 60fps doesn't - but the reality is that most people are using some mezzanine compression to reduce the data rates of 4K significantly. TICO is one such system)
