Abstract<\/span><\/h2><\/div><\/div><\/div>\n\n\n

This paper investigates the tile quality selection problem in multi-quality tiled 360\u00b0 video streaming. We consider 360\u00b0 video quality assessment (VQA) metrics, with the objective of maximizing the quality of the user\u2019s viewport in bandwidth-constrained communication. We formulate the problem as a multiple-choice knapsack problem (MCKP) and apply a greedy algorithm to solve it. The simulation results validate the advantages of our proposed method, demonstrated as an improvement in the viewport\u2019s weighted-to-spherical peak signal-to-noise ratio (WS-PSNR).<\/p>\n\n\n
