Abstract
A method for reduced-bandwidth wireless 3D video transmission includes receiving initial first-eye frame data, reprojecting the initial first-eye frame data to the second eye (which creates initial second-eye frame data), receiving sensor data; time-warping the initial first-eye and second-eye frame data, and receiving next second-eye frame data S140. The method can additionally or alternatively include perspective warping the initial first-eye frame data; reprojecting the next second-eye frame data to the first eye (which creates next first-eye frame data); performing infilling on the next first-eye frame data with the perspective-warped initial first-eye frame data; time-warping the next first-eye and second-eye frame data; and/or encoding transmitted frame data with sensor data.
