In the end it proved to o costly for the budget and JAXA included HDTV cameras instead. NHK (who paid to have the HD cameras onboard the spacecraft) had to build a prototype system from scratch as very little in the field had been tried.
The spec of the prototype system had a resolution of 7680×4320 pixels at 60 frames per second. The UHDV format is four times as wide and four times as high as current HDTV, used a camera built from four 2.5 inch CCDs and used 16 HD recorders.
The 18 minutes of UHDV test footage took up 3.5 terabytes of data. When they got a test audience to view the footage, most of them got motion sickness because the image was too good and so close to reality.
Blu-Ray is out of date...
This is why this technology has no use outside of maybe outdoor advertising, sporting events, concerts, etc. It's not financially reasonable, it's unweildy large, and storage space is going to be a consideration for a while (and since Blu Ray is a storage medium and this is a resolution medium it's also not really applicable to say BD is out of date since you have to store UHDV somewhere and BD has the largest storage capacity of any current optical media).
