Further, Table 2B shows on HD1080p test set that <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec in TU1 mode with<br />
respect to HM14 reference, results in the biggest luma BD rate percentage difference on BQTerrace 1080p<br />
sequence and the smallest luma BD rate percentage difference on Ducks_take_off 1080p sequence; the<br />
corresponding RD comparison curves for TU1 mode for the two cases are shown in Fig. 6B1.<br />

Table 2B 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 BQTerrace 1080p sequence and the smallest<br />
