XT3

XT3 is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand XT3 rather than just read about it. In short: XT3 is a model of the XT video server. It was created in 2011 by Belgian company EVS Broadcast Equipment.

Key takeaways

XT3 belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect XT3 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of XT3 from memory before moving on to harder problems.

Reference excerpt

XT3 is a model of the XT video server. It was created in 2011 by Belgian company EVS Broadcast Equipment. XT is end-of-support since December, 31 2023

Features This video server was built and designed to allow broadcasters to record, control and play media. It is capable of handling up to 12 channels of SD/HD, 6 channels of 3D/1080p (3G or dual link), as well as 3 channels in 4K resolution.

The tapeless server allows loop recording and functions such as replays, slow-motion, non-linear editing or streaming while recording. The server is controlled by Multicam(LSM) or IPDirector software. With the Multicam(LSM), instant replay of any live camera angle at variable speed is possible. The server inspired the XS model, dedicated to specific studio environments and controllers.

Applications XT servers have been used in global sporting events productions such as the FIFA World Cup, the IFAF World Cup, MotoGP, Formula 1, BBC Football Programmes, the Olympic Games and in studio environments such as NBC, Sky, France 2 and CCTV or others. This configuration is used in most OB vans around the world. and has received Emmy Award for this.

Worked examples

Example 1 — a first encounter with XT3

Start with the simplest possible case. Write down what XT3 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, 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 XT3 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 XT3 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 XT3

In research: XT3 appears in engineering 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 XT3 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: XT3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Broadcast engineering, Video, so understanding it makes those chapters shorter.
In everyday life: Look for XT3 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.

Frequently asked questions

What is XT3 in simple terms?

XT3 is a model of the XT video server. It was created in 2011 by Belgian company EVS Broadcast Equipment.

Why does XT3 matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study XT3?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
