Average decoding speed for 1080p resolution content is 35 *Other names and brands may be claimed as property of others.
oughly 4 times that of 4K resolution content (Table 4B vs Table 4A), average decoding speed of 720p resolution content is almost a factor of 1.6 of 1080p content (Table 4C vs Table 4B), and that of SD/XD resolution content is close to a factor of 2 as compared to decoding speed of HD720p content (Table 4D vs Table 4C). Deliver High Quality, High Performance HEVC via Intel® Media Server Studio 36 Further, Fig. 10 shows a combined graph of variation of Media Server Studio HEVC Software Decoder performance (fps) across various resolutions test sets. On the Haswell platform, including the rendering overhead, one 60 fps UHD4K stream or two 30 fps UHD4K streams, or up to eight HD1080p streams can be easily decoded in realtime. Intel® Media Server Studio HEVC Software Encoding Computational Scalability Tests (on E5 Server) For measurement of computational scalability beyond 4 core i7-4770K system used in tests thus far, an E5 Server (Intel® Xeon® Processor E5-2697v2, 12 Core, 2.7 GHz, 2 processors per board, total of 24 physical cores) is employed. Currently such servers do not inherently support Intel® graphics acceleration. The purpose of this test is to demonstrate threading scalability of the Intel Media Server Studio HEVC software encoder when many more cores are available. This also addresses an application where very high resolution video (4K and above) is needed to be HEVC encoded in realtime in software on many available cores. Quality Evaluation Results for Computational Scalability Tests for 4:2:0 8-bit Using the test set of 4:2:0 8-bit content as discussed earlier via Tables 0A-0B and test procedure establish earlier, we first evaluate video quality of the Intel® Media Server Studio HEVC for the three main TU modes, ie, TU1, TU4, and TU7, for the encoding configuration used to provide high degree of scalability. The results of quality tests are shown in Tables 5A and 5B for UHD4K and HD1080p test sets respectively.
