No it isn't proprietary.  It was developed jointly between VRex, 
StereoGraphics, NuVision, Canopus and possibly some others.

This all depends on what application you are using to generate your
images and the quality/resolution of the stereo pair images you are 
using.

I've used Adobe Photoshop very successfully to generate JPS images
from left and right image pairs.  Check out:
