Further, Table 2C shows that <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec in TU1 mode results in the biggest BD rate<br />
percentage difference for luma on Crew 720p sequence and the smallest BD rate percentage difference in<br />
luma on Ducks_take_off 720p sequence with respect to HM14 reference; the corresponding RD<br />
comparison curves for TU1 mode for the two cases are shown in Fig. 6C1.<br />
