Table 2C also shows that <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec in TU4 mode results in the biggest BD rate<br />
percentage difference for luma on Crew 720p sequence and the smallest BD rate percentage difference<br />
for luma on Ducks_take_off 720p sequence with respect to HM14 reference; the corresponding RD<br />
comparison curves for TU4 mode for the two cases are shown in Fig. 6C2.<br />

Next, Table 2D shows BD rate percentage differences of <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> wrt HM14 on the<br />
SD/XD test set. The average luma BD rate percentage difference of <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec over<br />
HM14 reference is 0.07%, 19.44%, 39.33%, and 44.65% respectively for TU1, TU4, TU7, and TU7gacc modes.<br />
