History

2012 On February 29, 2012, at the 2012 Mobile World Congress, Qualcomm demonstrated a HEVC decoder running on an Android tablet, with a Qualcomm Snapdragon S4 dual-core processor running at 1.5 GHz, showing H.264/MPEG-4 AVC and HEVC versions of the same video content playing side by side. In this demonstration HEVC reportedly showed almost a 50% bit rate reduction compared with H.264/MPEG-4 AVC. On August 22, 2012, Ericsson announced that the world's first HEVC encoder, the Ericsson SVP 5500, would be shown at the upcoming International Broadcasting Convention (IBC) 2012 trade show. The Ericsson SVP 5500 HEVC encoder is designed for real-time encoding of video for delivery to mobile devices. On the same day, it was announced that researchers are planning to extend MPEG-DASH to support HEVC by April 2013. On September 2, 2012, Vanguard Video, formerly Vanguard Software Solutions (VSS), announced a real-time HEVC software encoder running at 1080p30 (1920x1080, 30fps) on a single Intel Xeon processor. This encoder was demonstrated at IBC 2012. On September 6, 2012, Rovi Corporation announced that a MainConcept SDK for HEVC would be released in early 2013 shortly after HEVC is officially ratified. The HEVC MainConcept SDK includes a decoder, encoder, and transport multiplexer for Microsoft Windows, macOS, Linux, iOS, and Android. The HEVC MainConcept SDK encoder was demonstrated at the IBC 2012 trade show. On September 9, 2012, ATEME demonstrated at the IBC 2012 trade show a HEVC encoder that encoded video with a resolution of 3840x2160p at 60 fps with an average bit rate of 15 Mbit/s. ATEME is planning to release their HEVC encoder in October 2013.

Worked examples

Example 1 — a first encounter with High Efficiency Video Coding implementations and products

Start with the simplest possible case. Write down what High Efficiency Video Coding implementations and products claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to High Efficiency Video Coding implementations and products before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about High Efficiency Video Coding implementations and products ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of High Efficiency Video Coding implementations and products

In research: High Efficiency Video Coding implementations and products appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses High Efficiency Video Coding implementations and products in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: High Efficiency Video Coding implementations and products is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer file formats, Graphics file formats, H.26x, so understanding it makes those chapters shorter.
In everyday life: Look for High Efficiency Video Coding implementations and products outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
