Figure 15B Average encoding speed of all 4:2:0 10-bit test sets on <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Software Encoder<br />
<strong>Quality</strong> vs <strong>Performance</strong> Tradeoff for TU Modes for 4:2:0 10-bit Content<br />
We now discuss results of Codec <strong>Quality</strong> vs Encoding <strong>Performance</strong> tradeoffs for all modes for <strong>Media</strong><br />
<strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Encoder for all 4 resolutions tested.<br />
Figure 16 shows a comparison of <strong>Quality</strong> (negative BD rate percentage difference wrt <strong>HEVC</strong> HM14) vs<br />
Encoding <strong>Performance</strong> (fps) for each of the two resolution test sets at each of the three TU1, TU4, and<br />
TU7 encoding modes. The y-axis basically shows the quality difference in terms of loss of BD rate<br />
percentage difference in the process of increasing speed up of the encoder in going from TU1 to TU4 to<br />
TU7 operating points.<br />
To summarize, for 4:2:0 10-bit content, encoding performance-wise <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> codec in<br />
different modes achieves the following speedup of <strong>HEVC</strong> encoding on 4 core Reference PC platform<br />
specified earlier.<br />
<strong>Deliver</strong> <strong>High</strong> <strong>Quality</strong>, <strong>High</strong> <strong>Performance</strong> <strong>HEVC</strong> <strong>via</strong> <strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong><br />
