HD 101: What is ATSC, PSIP, QAM, and 8-VSB?
by Ben Drawbaugh posted May 8th 2009 at 11:54AM 
Once you buy an HDTV it doesn't take long before you get confused by all the acronyms. We love us some HD, but the days of simply bringing a new set home and plugging into a coax cable are long over -- at least for most. It is pretty obvious by the latest surveys that most people don't understand exactly what it takes to enjoy HD on their HDTV, but even if you do, you may not understand what most of it means. Now while this isn't the typical make sure you have your HDTV configured to watch HD post, it will help you understand the different ways HD is delivered.
DivX fills in the gaps and adds MKV support to Windows 7

Windows 7 comes with many new under the hood enhancements that address some sore spots for Media Center fans, but we don't think any hurt as much as the lack of native codec support. The most popular file format online today is without a doubt MKV, but many don't understand that it isn't a codec at all, but instead a container. In fact it's a container that can hold just about any combination of video and audio, but most notably H.264 video and AC3 audio. Now the kicker in Windows 7 is that although it natively supports H.264 and AC3, it still can't play MKV files. Up until now enthusiasts have been installing the Haali splitter on the Windows 7 Beta, which has kinda worked. We say kinda, because for whatever reason the Haali Media Splitter exposes the H.264 stream in an MKV file as AVC1 and not H.264. What this means is that Windows doesn't realize it can decode the content natively and when you try to play one of these files on an Extender -- for example -- the video is unnecessarily transcoded. So now that you understand the problem, it appears DivX has the solution. The latest DivX Tech Preview features a Media Foundation -- the replacement for DirectShow in 7 -- component that will demux MKV files and allow the video and audio streams to be decoded with native Windows 7 codecs. Well, that's the theory anyways, we'll be following the comments closely to see how this turns out in practice.
Hi-Def disc audio demystified

We gave this a go some time ago, but compared to the job Hi-Def Digest did, ours is pathetic. Not only do they go into detail about what every audio format available for both HD disc formats is all about, but they go on to give examples of discs that include them, and to top it all off, how to enjoy them. It's more complicated than you think because not every player or connection method supports every audio format. To be honest it's far more complicated than it should be and we wonder how anyone could make heads or tails of this mess without being very dedicated. Lucky for us, Joshua Zyber is up to the challenge and his article should help clear things up for just about everyone.
