SageTV

SageTV is a science 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 SageTV rather than just read about it. In short: SageTV is a free and formerly proprietary, open-source media center application and digital video recorder software for Windows, Linux, and formerly macOS. The SageTV software has an integrated Electronic Programming Guide (EPG) that is updated via the Internet.

Key takeaways

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

Reference excerpt

SageTV is a free and formerly proprietary, open-source media center application and digital video recorder software for Windows, Linux, and formerly macOS. The SageTV software has an integrated Electronic Programming Guide (EPG) that is updated via the Internet. The program provides a television interface for DVR, music, and photos on Windows and Linux. SageTV Media Center typically records in standard MPEG2, making it possible to transfer recordings to laptops or other devices. It also has a built-in conversion feature to transcode files into other formats compatible with iPod, PSP, cell phones and other portable devices. A "lite" version was commonly shipped as part of an OEM software bundle. Both the lite and regular versions offer a Java API. SageTV Placeshifter allows the user to watch TV from any high speed internet connection, similar to the Slingbox. As of Version 6, the SageTV Placeshifter is available for Windows, Linux and Macintosh platforms. The SageTV Media Extender set-top allows other TVs to connect to SageTV over a home network. There is also the ability to use the Hauppauge MediaMVP with SageTV by purchasing a MediaMVP Client License. On June 18, 2011, Jeffrey Kardatzke, CTO and founder of the company, announced in a SageTV forum post that his company had been acquired by Google. An official press release followed later the same day, and since then the SageTV products have no longer been available for purchase. On March 9, 2015, Jeffrey Kardatzke announced that SageTV would be open-sourced "in the near future (i.e. months, not years)". Then a few months later, SageTV became open source, hosted on GitHub.

Google Fiber After the acquisition of SageTV, LLC by Google, they began modifying and updating it to work with Google's upcoming Google Fiber TV service. SageTV v8 was the initial platform used for the Google Fiber Storage Box (DVR) and TV Box (Client). It has since been replaced with an in-house developed software.

SageTV Media Center for Linux SageTV Media Center for Linux is compatible with most major Linux distributions. Information on a Gentoo distribution tuned for Media Center usage is available from the SageTV website. It runs on low cost PC and consumer electronics hardware including embedded processors (embedded only available for OEMs).

SageTV Studio SageTV software also includes a SageTV Studio Development GUI that allows the customization of the user interface and development of add-ons. The company provides documentation so that these customizations can use a Java API. Built-in EPG support is available only for North America; however, the developer community has developed plug-ins that allow unsupported regions to access EPG info through sources such as XMLTV and ICETV in Australia. Additionally, there are IMDb and commercial skipping plugins.

Worked examples

Example 1 — a first encounter with SageTV

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

In research: SageTV appears in 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 SageTV 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: SageTV is common in secondary-school and first-year university syllabi. It links to neighbouring topics Digital video recorders, Discontinued Google acquisitions, Google acquisitions, so understanding it makes those chapters shorter.
In everyday life: Look for SageTV 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 SageTV in simple terms?

Why does SageTV matter?

Because it connects several science 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 SageTV?

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.
