Figure 17B1 RD results of 4:2:2 8-bit HD720p scenes with the biggest and the smallest quality difference
wrt HM14 for Media Server Studio TU1 mode
Table 13B also shows that on 4:2:2 8-bit 720p test set, Media Server Studio HEVC Codec in TU4 mode with
respect to HM14 reference, results in the biggest luma BD rate percentage difference on CrowdRun
sequence and the smallest BD rate percentage difference for luma on Ducks_take_off sequence; the
corresponding comparison curves for TU4 for the two cases are shown in Fig. 17B2.

Figure 17B2 RD results of 4:2:2 8-bit 720p scenes with the biggest and the smallest quality difference wrt
HM14 for Media Server Studio TU4 mode
To summarize, for 4:2:2 8-bit content the luma BD rate percentage bitrate difference of the Media Server
Studio HEVC in various modes with respect to an ideal (but slow) HM14 reference is as follows.
56
TU1 mode is only around 5% worse in BD rate as compared to HM14 on all test sets. This is highest
quality mode in Media Server Studio.
TU4 mode is 14.5 - 17% worse in BD rate as compared to HM14. As shown later, this mode provides an
excellent tradeoff of quality vs speed.
