Table 1	MD5 checksum for video sequences
Figure 12	A chart showing variation in FS bit rate values for different viewports: 3 vertically and 8 horizontally adjacent positions. The FS bit rate is calculated using the advertised bit rate for the highest quality for viewport tiles and lowest quality for non-viewport tiles
Table 2	Test Sequences
Figure 14	An illustration of the head motion; each point represents the center of viewport at a given time, the colour lightens with the passage of time changing in the order red-orange-yellow-white. The first viewport is marked with a black diamond. Note that the grid on the sphere is shown for clarity
Figure 15	The 6x4 tile grid was able to not only achieve a higher quality viewport, but was able to maintain the quality during head motion better than the 4x3 grid for most cases. Results for human and no head motion (none) are shown
Figure 16	Stacked graph showing ratio of the viewport tiles at different quality levels (1-5)
Figure 17	Average throughput for the different sequences and network bandwidth shown here with error bars
Table 3	Total Stall Duration
Figure 18	A timeline showing the adaptation of quality levels
Figure 19	Symmetric (left) and HMS (right) margins
Figure 20	Average MTHQD results with tile configurations of 6x4 (left), 8x6 (center) and 12x8 (right)
Figure 21	Average MTHQD results for human tests
