Visbit streams 12k 360 video wirelessly with VVOS technology


360 video cloud streaming service Visbit was able to stream 360 video in 12k resolution - wirelessly -  for exceptional detail.
When viewing 360 videos, we only see a small crop of the entire frame of the video at any given time.  This means that the resolution will appear much lower than a non-360 video of the same nominal resolution.  To see a video with the same detail that we see with 20/20 vision, the video would have to be in 16k, which would have 60 pixels per degree of rotation.



There are currently very few 360 cameras that are capable of such resolution (Voke VR is an example).   Visbit is a cloud streaming service for 360 video that has been able to demonstrate 12k 360 video, which begins to approach the 16k ideal resolution.  Moreover, they were able to stream the video.

Ordinarily, streaming 12k video would require very high bandwidth that is not readily available.  Visbit was able to stream the 12k video with their Visbit View-Optimized Streaming (VVOS) which uses foveated streaming, i.e., only the visible portion is streamed at high resolution.  With VVOS, Visbit was able to stream 12k wirelessly, at currently available bandwidths.  Here is a video that talks about VVOS:



Here is the demo video showing VVOS in use with a Samsung S7 and a Samsung Gear VR headset:

  1. Thanks Mic. The chart alone was worth reading this article. The additional information in the article was interesting as well. Double good. Having not yet watched the video on how VVOS works, I wonder how quickly the resolution can be updated based on the viewers POV, considering they may look in any direction at any time.

    1. Thanks Rich. That's a good question. They do say "little or no lag" which seems to imply that it can cope with even rapid head movement. I'll ask them to try to find out.

      Best regards,
      Mic
