<strong>Deliver</strong> <strong>High</strong> <strong>Quality</strong>, <strong>High</strong><br />

<strong>Performance</strong> <strong>HEVC</strong> <strong>via</strong> <strong>Intel®</strong><br />

<strong>Media</strong> <strong>Server</strong> <strong>Studio</strong><br />

A white paper unlocking new video technology opportunities!<br />

Introduction<br />

<strong>HEVC</strong> (aka, H.265) [1-4] is a new, highly efficient, video compression standard from ISO MPEG that promises<br />

substantially higher compression over H.264 (aka, AVC) [4,6], its previous generation standard completed around<br />

10 years ago. In particular <strong>HEVC</strong> promises roughly a factor of 2 in compression over H.264, that had delivered a<br />

factor of 2 in compression over MPEG-2, its earlier generation standard. H.264 is currently dominant having<br />

supplemented or displaced MPEG-2 in nearly all digital video applications, services, products, and eco-systems.<br />

Over next few years the time seems ripe for <strong>HEVC</strong> due to its advantages, to supplement or displace H.264 in the<br />

same manner. Overall MPEG has an excellent history [4] of delivering on video standards that have a wide<br />

industry following.<br />

<strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> SDK (formerly, <strong>Media</strong> SDK) is a well-known developer product that implements state<br />

of art standards based highly optimized decoders, corresponding efficient and highly optimized encoders,<br />

file/stream formatting, and pre- and postprocessing tools supporting efficient coding. <strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong><br />

SDK implements many Codec and tools components initially in software, and later as hybrid (of software and<br />

hardware) or entirely in hardware. The reason for this multi-tier approach is faster time to market for software<br />

solutions, followed by hybrid solutions that contains partial hardware acceleration, and lastly blazingly fast<br />

hardware solutions that scale. <strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> SDK 2015 is available both for Windows and Linux. It<br />

supports <strong>Intel®</strong> 4 th and 5 th generation Core and Xeon ® Processor based platforms with Intel Iris Pro and Intel<br />

HD Graphics.<br />

<strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> 2015 is just being released and includes a number of significant tools, technologies,<br />

and enhancements including improved software implementation of <strong>HEVC</strong> Encoders and Decoders. Since not all<br />

<strong>HEVC</strong> implementations are created equal, this white paper attempts to quantify the quality and performance a<br />

developer should expect from <strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> Codec software implementation. Rest of the<br />

white paper is organized as per following sections.<br />

<strong>HEVC</strong> Compression Basics<br />

<strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> Overview<br />

<strong>Intel®</strong> <strong>Media</strong> <strong>Server</strong> <strong>Studio</strong> <strong>HEVC</strong> R7 release (Codec <strong>Quality</strong>, Encoder <strong>Quality</strong> vs <strong>Performance</strong> Tradeoffs,<br />

and Decoder <strong>Performance</strong>) results presented in 4 parts as follows.<br />

o Part 1: 4:2:0 8-bit Coding <strong>Quality</strong>, <strong>Performance</strong>, and Computational Scalability Tests<br />

o Part 2: 4:2:0 10-bit Coding <strong>Quality</strong>, and <strong>Performance</strong> Tests<br />

o Part 3: 4:2:2 8-bit, and <strong>Performance</strong> Tests<br />

o Part 4: 4:2:2 10-bit, and <strong>Performance</strong> Tests<br />
