For instance, Table 9A shows on UHD1600p 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 UHD1600p 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 5.38%, 23.29%, and 44.69%, higher respectively in TU1, TU4, and TU7 modes. This means that<br />
for UHD1600p test set, the <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> codec as compared to HM14, requires around 5% higher<br />
bitrate in TU1 mode, 23% higher bitrate in TU4 mode, and 45% higher bitrate in TU7 mode to achieve the<br />
same luma PSNR quality as HM14.<br />

Further, Table 9A shows on UHD1600p test set that <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec TU1 mode with<br />
respect to HM14 reference, results in the biggest luma BD rate percentage difference on Nebuta_Festival<br />
sequence and the smallest luma BD rate percentage difference on SteamLocomotive sequence; the<br />
