Microsoft obviously has a more complicated relationship with "industry" standards, because anything it decides is its standard—even proprietary ones—becomes a kind of de facto standard for everybody else, simply because of Microsoft's overwhelming marketshare. This was more true in the past than today, with Microsoft playing ball with everybody else more often.

Microsoft's AV Club
Let's start with Windows Media Audio—most commonly, it's known as Microsoft's proprietary audio codec that at one point fought the good fight against MP3, but is now much more, having grown into a sprawling family of various codecs with multiple versions. To name a few of the current ones, there's WMA 9, WMA 9 Lossless and WMA 10 Pro. Microsoft says it offers superior quality/compression over MP3, with "CD quality at data rates from 64 to 192 kilobits per second." Needless to say, while it's baked into Windows Media Player for ripping CDs and is supported by a fairly wide range of PMPs and phones, it obviously never displaced MP3, nor is it ascendant as the "new" standard like AAC (the official successor of MP3), basically since it isn't supported by the iPod, which owns over 70 percent of the MP3 player market. WMA Pro, despite being an even better codec than WMA, has more limited support still, mostly with Microsoft's own hardware, like the Xbox 360 and Zune.

WMA's more ignoble legacy, undoubtedly, is PlaysForSure, Microsoft's grand attempt to standardize the entire digital music industry (except Apple, or rather, against Apple) by getting everybody on the same page. PlaysForSure was technically a certification for players and services with a variety of requirements, but support for WMA, WMV and Windows Media DRM is what it amounted to in practice. Microsoft succeeded, for a time: Pretty much every PMP maker and services from Walmart, Rhapsody, MSN Music, Yahoo, Napster and others were all aboard PlaysForSure. Then it imploded. As every real music service went to DRM-free MP3, Microsoft re-branded it to Certified for Windows Vista. Which, incidentally, was a badge they slapped on the Zune, Microsoft's own audio player that didn't actually support PlaysForSure. When Microsoft ditched its own standard for its premiere player, everybody knew PlaysForSure was dead.

Windows Media has been more successful on the video front, with WMV. Like WMA, it's gone through multiple versions: At one point (WMV 7) merely Microsoft's take on the MPEG-2 standard, Microsoft actually succeeded in making it a genuine industry standard, with WMV 9 becoming the basis for the VC-1 codec that's backed by the Society of Motion Picture and Television Engineers. VC-1 is part of the spec for both HD DVD and Blu-ray, though at this point it's really just an alternative to H.264, which is becoming the dominant modern video codec. WMV saw some success as the codec of choice for some services during the heyday or PlaysForSure (since WMV support was part of the certification), but now it sees a lot of action as the video codec for Silverlight, Microsoft's Adobe Flash competitor.

Internet Exploder
Silverlight itself actually isn't doing so bad, considering it's fighting Flash, which is installed on the vast majority of internet-connected computers, powering Netflix's streaming service and last summer, NBC's streaming Olympics coverage. But like Flash, it's proprietary, which is obviously a bit disconcerting for people who want an open web. Which brings us to Internet Explorer. The early history of IE and Netscape is grossly complicated, but suffice it to say, being included with Windows eventually gave IE over 90 percent of browser marketshare. In other words, Microsoft defined how an overwhelming majority of people looked at the internet for years—meaning it essentially defined what the internet look like. Microsoft essentially stopped moving forward with IE6, sitting on its ass for years, which is a problem since it's totally non-compliant with what most people would call modern web standards. (Short version: Web developers hate IE6.) With IE8, which entered a new world with Firefox having devoured a huge chunk of its marketshare, Microsoft supports actual real web standards (mostly—it still fails the Acid3 test miserably). And, they're actually serious about HTML5, even though they're not planning to implement the controversial video aspect at all.

Do You Trust Me?
Obviously, Microsoft's in an odd spot in part because the constant specter of antitrust allegations hang over its head—it's had to de-couple Internet Explorer from Windows in Europe, and it's moved to separate other stuff from the core OS, like even its mail, video and photo applications, making it harder to achieve the kind of de facto standards through sheer force of market like before.

Which might be part of the reason it's moving to make tech legit industry standards—besides VC-1 above, for instance, its HD Photo has become the basis for the successor to JPEG, now dubbed JPEG XR. Also, it's simply that standards matter more now than ever as people do more and more of their computing on the web, on multiple platforms from Windows desktops to Android phones, so industry-wide standards are way preferable to proprietary formats, even if most people still are on Windows.

Increasingly, if Microsoft wants people to use their tech, they're going to have to open it up in the same quasi-way Apple has (it'll also go a long way with the whole trust/control issues people have with Microsoft). So don't surprised if you see Microsoft continue to "open up" and "standardize." Just don't be surprised if the standards they embrace have Microsoft tech at the core.

Once upon time, video codecs and formats were really only the concern of AV nerds, anime freaks and hardcore not-so-legal movie downloaders. Now, even the most part-time of geeks has to deal with them, whether they're trying to stream a flick across their house with an Apple TV, dump some video onto their phone or just trying to grab last night's episode of Dexter because they, uh, forgot to renew their Showtime subscription. It's messy and annoying, but we're here to clean it up. Take a deep breath.

You might recall our discussion about video bitrates earlier, or how much data is packed into a file. As a general rule, more bits per second translates into more betterer quality audio and video. The variable in that—the other part of the equation—is how the content is compressed and de-compressed. Better compression techniques—the zen of knowing what bits of data to pull out to make big data chunks smaller—make for better quality video while taking up less space on your hard drive. Basically, the part you need to know is that codecs are the software that make that magic happen.

Standard Standards
• H.261 is not a term you have to worry about, but it's the technology that most video standards and codecs were originally based on. Originating in 1990, it's the first major digital video compression standard, and like other "H" standards, it was developed by the International Telecommunication Union. This one was primarily for teleconferencing over ISDN lines, and as such, it looks like ass.

• MPEG-1 Part 2 is another oldie, developed by the Movie Picture Experts Group and approved in 1991. (BTW, the whole "part" thing is because video is just one "part" of each MPEG standard.) Based quite a bit on H.261, MPEG-1 was designed to take VHS quality video and squeeze it down to a bit rate of about 1.5Mbps, optimized for CD transfers. No surprise, it's the standard used for all VCDs (which can play in most DVD players), but not a standard you would see hanging around today.

• With MPEG-2 Part 2, approved in 1994, we're finally talking decent vid. Also known as H.262, since it was developed jointly by the ITU-T and ISO, MPEG-2 is an extension of MPEG-1 that delivers better resolution and higher bit rates (3-15Mbps for standard def and 15-30Mbps for HD, though the spec allows for up to 100Mbps). It's the video codec used by DVD and digital television, though now it's slowly being replaced by the more efficient MPEG-4, except on DVDs, where it'll ride out that disc format's lifetime.

• H.263 is designed for sending video over crappy connections. So it's used to encode most Flash video and to send video over mobile networks.

• MPEG-4 is where we really stand right now. It has a much broader scope than past MPEG standards, aiming to tackle both the low end (crappy cellphones on a crappy network) and the high end (Blu-ray). It's still developing, so it's not-so-coincidentally where this whole story gets messier. There are two relevant parts of the MPEG-4 standard for our myopic video purposes: There's Part 2. And there's Part 10—which is also known as H.264 or Advanced Video Coding (AVC). To be clear though, even though they're both part of the MPEG-4 standard, they're totally different formats. Nevertheless, both are more efficient at compression than past MPEG codecs, delivering better quality using less space.

• Okay, so if you've ever frequented a Torrent site, you've actually watched tons of videos that use MPEG-4 Part 2, though it's not like they would've had a flashing sign telling you so. MPEG-4 Part 2 actually has different "profiles"—the two that matter being Simple Profile, for low bitrate, low-res stuff, and Advanced Simple Profile. The latter profile is what's used by movies you would download in formats like DivX or XviD or 3ivx—which are all codecs that are essentially just differing implementations of the MPEG-4 Part 2 standard.

• MPEG-4 Part 10, the other part, was actually co-devopled by MPEG and the ITU-T, so it's also known—in fact, more commonly known—as H.264. It's more efficient than MPEG-2 and MPEG-4 Part 2, delivering the same quality video in as little as half the space, making it suitable for the low and high-end. Because of this, it's quickly becoming the standardest standard. It's part of the HD DVD and Blu-ray spec, replacing MPEG-2 in digital TV (like with satellite services and AT&T's U-Verse IPTV) and supported by pretty much every portable video player on the planet from the iPod to the PSP. Apple has a decent, if Kool-Aid flavored, FAQ about H.264.

• VC-1 is essentially a Microsoft developed alternative video codec to H.264 released as a standard by the Society of Motion Picture and Television Engineers, though it descends from the same H.26X/MPEG family. (It essentially started life as WMV9, but then Microsoft shopped it to the SMPTE to make it an industry standard, and now it is.) It too, is part of the mandatory Blu-ray and HD DVD spec, and is the official video codec of the Xbox 360. It's pitch is the same as H.264's—trying to deliver better quality using less space, like HD video in 6-8Mbps.

Free-Floating Codecs
Okay, so all that stuff up there are industry-wide standard video codecs. On top of all of those, various entities love putting out their own spin on those standards. As we mentioned before, DivX (proprietary) and XviD (open source), for instance, use MPEG-4 Part 2 (more specifically, MPEG-4 ASP) compression, meaning stuff that'll natively play back MPEG-4 ASP will also play back DivX. Like the Xbox 360, for instance. There are a ton of MPEG-4 ASP-based codecs, actually, like FFmpeg, 3ivx and others, but DivX and XviD are the most common. Same deal with H.264: Some well known codecs that use it are Apple's Quicktime H.264, x264 and Nero Digital. You've also got Windows Media Video (WMV) codecs, which are Microsoft's proprietary twists on industry standards.

Containers aka Wrappers
Alright, well you've probably noticed that none of your video files have the extension .h264 or .vc1 or the like. That's because videos are packaged in containers or wrappers that stuff things like the audio, navigational info, etc. along with the video in a single pretty file. Naturally, there are about as many of them as there are codecs. To be clear, you would take a video encoded with, say, H.264, and wrap it up as a .mp4 or .avi file.

The majors ones are:
• AVI (Audio Video Interleave) is Windows' standard multimedia container
• MPEG-4 Part 14 (known to you as .mp4) is the standardized container for MPEG-4
• FLV (Flash Video) is the format used to deliver MPEG video through Flash Player
• MOV is Apple's QuickTime container format
• OGG, OGM and OGV are open-standard containers
• MKV (Mastroska) is another open-specification container that you've seen if you've ever downloaded anime
• VOB means DVD Video Object. Guess what? It's DVD's standard container, and what you get when you rip a DVD.
• ASF is a Microsoft format designed for WMV and WMA—files can end in .wmv or .asf

So, in order to play a video file, your setup has to be able to handle both the actual video codec and the container. It's why you can try to play an AVI file and Windows Media Player laughs at you, even though it totally played one a minute ago— the container was no problem, but it didn't have the right codec. Or conversely, even though an iPod could play back an H.264 encoded video, if it was wrapped up in MKV, it won't be able to read it.

Okay, my brain hurts. Hopefully this will make yours hurt less when it comes to dealing with pesky videos. If you'd like to do even more homework, Wikipedia, as always, has a more in-depth discussion. And Doom9 is always an amazing resource for all things digital video.

Their Silverlight plug-in, which works not only with IE, but with Safari and Firefox (ha ha, Opera users) and essentially provides a browser plug-in that lets everyone stream WMV files like they do with flash files.

The improvement upon flash—and this is why people would want to use this instead of Adobe's—is that it's high-def. We don't have to explain to you how much better it would be to stream high-def TV shows from NBC or ABC if you missed them when they first aired. And with MLB, Netflix and others already supporting the format, Microsoft may already have some hope of dethroning flash. – Jason Chen

Big names back Microsoft's Silverlight browser plug-in [Seattlepi]

This "multimedia super dictionary" stores 20GB of useless words, MP3s, MPEG4s and WMVs. Plus, it packs full QWERTY, an SD slot and voice recording. The 4.3" TFT 260K-color display is just enough power to support the black and white nature of print, especially if you are using the built-in ebook functionality.

Our photo is of a predecessor that should be similar to the new $500, 1.2" thick model when it's released this month in Korea. A tiny picture on Sharp's site shows the RD-CX300 could come in red. Oooohhh. – Mark Wilson
