20-60x bandwidth requirements to be able to move your head around a little? Is it worth it?
- nullifidian 6y agoThey could probably cut it down significantly by only streaming a several-inch-sized sphere of free movement, predicting what segment to stream next. There is a limitation to how fast human beings can move/rotate their heads.
- faeyanpiraat 6y agoBandwidth is getting cheaper over time. Couple of years ago I got a 56K modem, and now 1gbps connections are getting mainstream.
- eptcyka 6y agoWhat you mean is, a couple of decades ago you got a 56k modem.
- PetitPrince 6y agoOn a flatscreen I would say it's just a gimmick. With a VR headset though, since you are constantly moving your head a little I would say it's a massive improvement over 180° 3D videos, and really helps with the feeling of "being there".
- dTal 6y ago20-60x the bandwidth requirements is one of the things that can reasonably be expected to improve with effort. Look at 2D video and how much better h264 is than, say, GIF. And the higher the dimensionality, the more data but also the more low-hanging fruit for compression. We had 100:1 lossy lightfield compression 20 years ago; we can likely put another zero on that, maybe more with machine learning. That's what the linked paper is about - effective representations for lightfield data. The field is just kicking off.
