Claim 8:
9. A method for generating a video, the method comprising:
obtaining Laplace pyramid levels of 360° video frames;
upscaling each of the obtained Laplace pyramid levels so as to recover a set of corresponding Gaussian pyramid levels for each 360° video frame;
determining a recovered Gaussian pyramid level among the set of corresponding Gaussian pyramid levels for each pixel in each 360° video frame based on a bitrate budget for live streaming and a viewport region, by performing a pyramid level assignment procedure; and
composing a 360° video with heterogeneous spatial quality based on summing up the recovered Gaussian pyramid levels for each pixel in each 360° video frame.
