Figure 14B1 RD results of 4:2:0 10-bit HD1080p scenes with the biggest and the smallest quality difference<br />
wrt HM14 for <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> TU1 mode<br />
Table 9B also shows that <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec in TU4 mode with respect to HM14 reference,<br />
results in the biggest luma BD rate percentage difference on CrowdRun sequence and the smallest BD<br />
rate percentage difference for luma on Seeking sequence; the corresponding comparison curves for TU4<br />
for the two cases are shown in Fig. 14B2.<br />

To summarize, for 4:2:2 8-bit content the luma BD rate percentage bitrate difference of the <strong>Media</strong> <strong>Server</strong><br />
<strong>Studio</strong> <strong>HEVC</strong> in various modes with respect to an ideal (but slow) HM14 reference is as follows.<br />
<br />
TU1 mode on average is only 2 to 4% worse in BD rate as compared to HM14 on all test sets. This is<br />
highest quality mode in <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong>.
