For instance, Table 13A shows on HD1080p test set, the BD rate percentage difference of <strong>Media</strong> <strong>Server</strong><br />

<strong>Studio</strong> <strong>HEVC</strong> in various TU modes wrt HM14 reference. As can be observed on HD1080p test set, the<br />

average luma BD rate percentage difference of <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec over HM14 (an ideal<br />

reference), is 5.1%, 16.9%, 33.7%, and 37.8%, higher respectively in TU1, TU4, TU7, and TU7gacc modes. This<br />

means that for HD1080p test set, the <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> codec as compared to HM14, requires around<br />

5% higher bitrate in TU1 mode, 17% higher bitrate in TU4 mode, 34% higher bitrate in TU7 mode, and 38%<br />

higher bitrate in TU7gacc mode to achieve the same luma PSNR quality as HM14.<br />

Further, Table 13A shows on 4:2:2 8-bit HD1080p test set that <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 />

TouchdownPass sequence and the smallest luma BD rate percentage difference on Red_Kayak sequence;<br />

Table 13A also shows that on 4:2:2 8-bit HD1080p 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<br />

Touchdown_Pass sequence and the smallest luma BD rate percentage difference on Red_Kayak sequence;<br />

the corresponding RD comparison curves for TU4 mode for the two cases are shown in Fig. 17A2.
