Universal Remote Console

Universal Remote Console is a astronomy 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 Universal Remote Console rather than just read about it. In short: Universal Remote Console (URC) is a standard for defining alternative user interfaces for devices that can be used remotely. In the vocabulary of URC, the remote devices are called "controllers", while the devices they control are called "targets".

Key takeaways

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

Reference excerpt

Universal Remote Console (URC) is a standard for defining alternative user interfaces for devices that can be used remotely. In the vocabulary of URC, the remote devices are called "controllers", while the devices they control are called "targets". The controller presents a user interface for the target that can be an alternative in various respects: the user interface language, its ease of use, its accessibility to persons with disabilities, etc. Since user interfaces in different devices or products ("targets") can vary a lot, Universal Remote Console would enable a user to control these products through a single device; this single device would present interfaces that are adapted to the user's needs. The communication between a target and a controller typically uses a wireless protocol; the URC standard does not restrict which protocols can be used. For example, the "Universal Remote Console on HTTP" (URC-HTTP) protocol is a protocol that can be implemented by servers that are compliant with UPnP RemoteUI (CEA-2014). URC is defined by standard ISO/IEC 24752. This standard builds on earlier work that started in the late 1990s and that was first standardised at the American National Standards Institute (ANSI INCITS 389–2005 to 393–2005). Most parts of the URC standard were updated in 2014, and a new part (web service integration) was added:

ISO/IEC 24752-1:2014: Information technology—User interfaces—Universal remote console—Part 1: General framework (revision of ISO/IEC 24752-1:2008) ISO/IEC 24752-2:2014: Information technology—User interfaces—Universal remote console—Part 2: User interface socket description (revision of ISO/IEC 24752-2:2008) ISO/IEC 24752-4:2014: Information technology—User interfaces—Universal remote console—Part 4: Target description (revision of ISO/IEC 24752-4:2008) ISO/IEC 24752-5:2014: Information technology—User interfaces—Universal remote console—Part 5: Resource description (revision of ISO/IEC 24752-5:2008) ISO/IEC 24752-6:2014: Information technology—User interfaces—Universal remote console—Part 6: Web service integration

Worked examples

Example 1 — a first encounter with Universal Remote Console

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

In research: Universal Remote Console appears in astronomy 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 Universal Remote Console 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: Universal Remote Console is common in secondary-school and first-year university syllabi. It links to neighbouring topics ISO/IEC standards, User interface markup languages, User interface techniques, so understanding it makes those chapters shorter.
In everyday life: Look for Universal Remote Console 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.
