WMV HD

WMV HD 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 WMV HD rather than just read about it. In short: Windows Media High Definition Video (WMV HD) is the marketing name for high definition videos encoded using Microsoft Windows Media Video 9 codecs. These low-complexity codecs make it possible to watch high definition movies in 1280×720 (720p) or 1920×1080 (1080p) resolutions on many modern personal computers running Microsoft Windows XP or Windows Vista, although the hardware requirements are steep.

Key takeaways

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

Reference excerpt

Windows Media High Definition Video (WMV HD) is the marketing name for high definition videos encoded using Microsoft Windows Media Video 9 codecs. These low-complexity codecs make it possible to watch high definition movies in 1280×720 (720p) or 1920×1080 (1080p) resolutions on many modern personal computers running Microsoft Windows XP or Windows Vista, although the hardware requirements are steep. Microsoft's Xbox 360 and Sony's PlayStation 3 video game consoles can also play WMV HD. WMV HD isn't a standalone video codec nor a special modification of the WMV9 codec. As of April 2006, all existing WMV HD titles are encoded using the VC-1 compliant Windows Media Video 9 (FourCC: WMV3) codec conforming to VC-1 Main Profile @ High Level specification. It is possible that in the future Microsoft will take advantage of the new VC-1 Advanced Profile codec dubbed Windows Media Video Advanced Profile (FourCC: WVC1) to encode WMV HD videos. A number of WMV9-encoded high definition movie titles have been made commercially available on DVD-ROM discs, either as standalone discs or supplements to the regular DVD-Video titles. The technology was considered a stepping stone to true high definition optical disc formats (HD DVD and Blu-ray Disc) and Microsoft never intended the discs to be played on anything but personal computers. Most commercially sold WMV HD titles are copy protected using Microsoft Windows Media DRM technology. The licensing terms of DRM protected titles are determined by the content providers and not Microsoft Corporation. The soundtracks are commonly encoded using the Windows Media Audio Professional codec, often featuring 5.1 or 7.1 multichannel sound. The video and audio streams are encapsulated in Advanced Systems Format files.

Compatibility WMV HD has been touted for its ease of use, since functionality to convert to WMV HD has been built into Windows Movie Maker, it has allowed people to convert their home videos to WMV HD as well as any commercial releases they may have received. The file system will work on a PC with the settings listed above, as well as an Xbox 360, at 1080p/1080i.

Encoders Windows Media Video HD can be encoded with a variety of programs, such as Windows Media Encoder, Windows Movie Maker, and Microsoft Expression Encoder. When encoding, it has been recommended by these programs that you use the original file for best results; at times, re-encoding an already-coded movie can lead to subpar results.

Worked examples

Example 1 — a first encounter with WMV HD

Start with the simplest possible case. Write down what WMV HD 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 WMV HD 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 WMV HD 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 WMV HD

In research: WMV HD 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 WMV HD 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: WMV HD is common in secondary-school and first-year university syllabi. It links to neighbouring topics High-definition television, so understanding it makes those chapters shorter.
In everyday life: Look for WMV HD 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 WMV HD in simple terms?

Why does WMV HD 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 WMV HD?

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.
