#StandardsGoals for 2024: What’s new for BISAC - Tech Forum 2024
Evaluation of bandwidth performance for interactive spherical video
1. Evaluation of Bandwidth Performance for Interactive Spherical Video Patrice Rondao Alface, Jean-François Macq, Nico Verzijp Bell Labs, Alcatel-Lucent ICME’s WoMAN’11, Barcelona, July 2011
14. Results (case 1: no delay) Tiling: client viewport quality vs. bandwidth
15.
16. Low delay: 40ms Quality is higher close to the estimated viewport High delay: 1280ms Low probability for any viewport position; quality tends to be constant on the whole panorama 15dB better than constant bitrate 7dB better than constant bitrate Results (case 2: user interaction delay) 75kB for 4Kx2K panorama
17. Results (case 2: user interaction delay) PSNR vs. Delay for a fixed bandwidth 75KBs
18. Results (case 2: user interaction delay) Discrepancy at the client side - delay of 1280ms
