Further, Table 17 shows that on 4:2:2 10-bit UHD4K test set, <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec TU1 mode<br />
with respect to HM14 reference, results in the biggest luma BD rate percentage difference on<br />
Venetian_Crossing sequence and the smallest luma BD rate percentage difference on Footbridge<br />
sequence; the corresponding RD comparison curves for TU1 mode for the two cases are shown in Fig. 21A.<br />

Table 17 also shows that on 4:2:2 10-bit UHD4K test set, <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec in TU4 mode<br />
with respect to HM14 reference, results in the biggest luma BD rate percentage difference on FastWalk<br />
sequence and the smallest luma BD rate percentage difference on Footbridge sequence; the<br />
corresponding RD comparison curves for TU4 mode for the two cases are shown in Fig. 21B.<br />

To summarize, the luma BD rate percentage bitrate difference of the <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> in various<br />
modes with respect to an ideal (but slow) HM14 reference is as follows.
