Deliver High Quality High Performance HEVC via Intel® Media Server Studio

From Fig. 22A it can be seen that the encoding speed of the TU1 mode is over 120 times (multithreaded on 4
cores) the speed of HM14 (single threaded/1 core) for the 4:2:2 10-bit UHD4K test set.
Next in Table 18 we show measurement of encoding speed of Media Server Studio HEVC Software
Encoder on each sequence on each of the three TU1, TU4, and TU7 modes.

Table 18 Encoding Speed of 4:2:2 10-bit UHD4K test set on Media Server Studio HEVC Software Codec in TU1, TU4, and TU7
modes. For reference the average Speed of HM14 Encoder for this test set is .004 fps.

2 Footbridge 0.68 3.94 12.11
3 Venetian_crossing 0.72 3.90 9.92
Average 0.55 3.52 9.72
As can be seen from Table 18 for the 4:2:2 10-bit UHD4K test set, the encoding speed of TU4 mode is 6.4
times that of TU1 mode, and that the encoding speed of TU7 mode is 2.8 times that of TU4 mode. In
other words TU7 mode reflects an overall speed of 17.7 times that of TU1 mode. Also, since TU1 for 4 core
multithreaded coding is 137 times the speed of HM, TU7 reflects a typical speedup factor of 2430 over
HM14!
A side-by-side comparison of encoding speed of different TU modes and for the 4:2:2 10-bit UHD4K
resolution test sets is shown next by the bar graphs of Fig. 22B.
