Reference excerpt

High Efficiency Streaming Protocol (HESP) High Efficiency Streaming Protocol (also known as HESP) is an HTTP-based adaptive bitrate streaming protocol that enables high-quality streaming of media content over the Internet delivered from conventional HTTP web servers, such as HLS and DASH. The technology was developed by THEO Technologies and made available via the HESP Alliance, which has Synamedia and THEO Technologies as founding members. HESP brings sub-second latency and a fast channel change and is seen as a challenger of Low Latency HLS (LL-HLS, added to HLS standard in 2020) and Low Latency DASH (LL-DASH, added to DASH standard in 2019).

Architecture HTTP-based streaming protocols such as HLS and DASH typically use a segment-based approach. This means a video is cut up into TCP segments of a few seconds each, which requires video players to wait until the start of a new segment to start playback. This approach increases channel change times and introduces additional latency. HESP leverages a frame-based streaming approach, which does not require a trade-off between live latency and channel switching time. When all components of the video workflow are optimized for low latency, HESP can provide for sub-second latency. HESP requires implementation in the packager and player, and support for range requests and Chunked transfer encoding (CTE) in the CDN.

Standardization Work on HESP started in 2018; it became an IETF information draft in May 2021 The HESP Alliance, launched in 2020, promotes and catalyzes the adoption of HESP. It consists of streaming vendors and media companies, including Synamedia, THEO Technologies, G-Core, EZDRM, Mainstreaming, NativeWaves, and Hoki. The HESP Alliance technical working group is focused on further advancing the HESP standard.

Worked examples

Example 1 — a first encounter with High Efficiency Streaming Protocol

Start with the simplest possible case. Write down what High Efficiency Streaming Protocol 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 Streaming Protocol 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 Streaming Protocol 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 Streaming Protocol

In research: High Efficiency Streaming Protocol 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 Streaming Protocol 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 Streaming Protocol is common in secondary-school and first-year university syllabi. It links to neighbouring topics Hypertext Transfer Protocol, Network protocols, Streaming media systems, so understanding it makes those chapters shorter.
In everyday life: Look for High Efficiency Streaming Protocol 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.
