Why would they stretch a 1920x540 image to 1280x 720??? Wouldn't they just double the vertical to 1920 x 1080? It would be easier, and what would be the point of generating a 1920 hrz rez frame knowing it's going to be reduced to 1280? This format would never be used, there is already a 720 3d format!
To me what they are doing is sort of interlacing, one frame holds 2 1080x540 frames, they are stretched to 1920x1080, In effect your getting 1920x1080 left and right frames updated every 1/60 sec. The frames are subsampled to 540 vertical, and then stretched to 1080, but at 60hz rate per stereo frame, it's an averaging interlacing, or at least that's what i'd call it.
