IEC 62379

IEC 62379 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 IEC 62379 rather than just read about it. In short: IEC 62379 is a control engineering standard for the common control interface for networked digital audio and video products. IEC 62379 uses Simple Network Management Protocol to communicate control and monitoring information.

Key takeaways

IEC 62379 belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IEC 62379 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IEC 62379 from memory before moving on to harder problems.

Reference excerpt

IEC 62379 is a control engineering standard for the common control interface for networked digital audio and video products. IEC 62379 uses Simple Network Management Protocol to communicate control and monitoring information. It is a family of standards that specifies a control framework for networked audio and video equipment and is published by the International Electrotechnical Commission. It has been designed to provide a means for entering a common set of management commands to control the transmission across the network as well as other functions within the interfaced equipment.

Organization The parts within this standard include:

Part 1: General, Part 2: Audio, Part 3: Video, Part 4: Data, Part 5: Transmission over networks, Part 6: Packet transfer service, Part 7: Measurement (for EBU ECN-IPM Group) Part one is common to all equipment that conforms to IEC 62379 and a preview of the published document can be downloaded from the IEC web store here, a section of the International Electrotechnical Commission web site. More information is available at the project group web site.

History

2 October 2008 Part 2, Audio has now been published and a preview can be downloaded from the IEC web store, a section the International Electrotechnical Commission web site.

31 August 2011 A first edition of Part 3, Video has been submitted to the IEC International Electrotechnical Commission technical committee for the commencement of the standardization process for this part. It contains the video MIB required by Part 7. Part 7, Measurement, has been submitted to the IEC International Electrotechnical Commission technical committee for the commencement of the standardization process for this part. This part specifies those aspects that are specific to the measurement requirements of the EBU ECN-IPM Group, a member of the Expert Communities Networks. An associated document EBU TECH 3345 has recently been published by the EBU European Broadcasting Union.

16 December 2011 Part 3 (Document 100/1896/NP) and Part 7 (Document 100/1897/NP) have been approved by IEC TC 100.

3 April 2014 Part 5.2, Transmission over Networks - Signalling, has now been published and can be downloaded from the IEC web store,

5 June 2015 IEC 62379-3:2015 Common control interface for networked digital audio and video products - Part 3: Video has now been published and can be downloaded from the IEC web store.

16 June 2015 IEC 62379-7:2015 Common control interface for networked digital audio and video products - Part 7: Measurements has now been published and can be downloaded from the IEC web store. IEC 62379-7:2015 is the standardised (and extended) version of EBU TECH 3345 - End-to-End IP Network Measurement - MIB & Parameters, which can be obtained from here: published by the EBU European Broadcasting Union.

Worked examples

Example 1 — a first encounter with IEC 62379

Start with the simplest possible case. Write down what IEC 62379 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 IEC 62379 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 IEC 62379 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 IEC 62379

In research: IEC 62379 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 IEC 62379 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: IEC 62379 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Audio engineering, Broadcast engineering, Control engineering, so understanding it makes those chapters shorter.
In everyday life: Look for IEC 62379 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 IEC 62379 in simple terms?

Why does IEC 62379 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 IEC 62379?

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.
