   480p is the same resolution as your standard TV, but when your TV goes to refresh the screen, it will redraw all 480 lines. This is known as progressive scan, hence the "p" in 480p. It's also called non-interlaced or "enhanced definition TV" (EDTV) There aren't many EDTV sets on the market anymore.

   Standard definition TV (SDTV), is 480i. This means the screen only redraws every other line – evens on one pass, odds on the next. This is known as interlaced – that's what the "i" stands for.

   Progressive scan gives you a more solid picture, without the flickering you sometimes get with normal TV. All computer displays use progressive scan.

   High definition TVs (HDTVs) support even higher resolutions – 720 or 1080 horizontal lines, compared to 480. The 3 common resolutions for HDTV are 720p, 1080i and 1080p. Most HD TV channels are in 720p. Only a few use 1080i. The only real sources of 1080p material is from HD-DVD and Blu-Ray discs – more on those later.

   HDTVs also contain an upscaler. This is a special computer chip that takes an incoming video signal, and intelligently stretches it to fit the resolution of the TV. This includes everything you'd plug into your TV – non-HD channels, HD channels, DVDs, games – everything. The upscaler isn't perfect. The better the incoming signal, the better the job the upscaler will do.

   Some DVD players also include an upscaler. In general, the upscaler chip in a DVD player is better than the ones in TVs.

   You'll probably encounter HD-DVD and Blu-Ray players. These are two competing formats for the next generation of DVD. These can hold a lot more data than a standard DVD, making them perfect for movies in HD. Right now, the market for these formats is too small and volatile. Give it at least another year before even worrying whether you should buy into these.

   Finally, when looking at a stereo receiver, the number of watts refers to how much power is being sent to each speaker. This isn't quite the same thing as sound volume, but it's sort of similar. Of course, this doesn't mean you can take a teeny-tiny speaker and pump 100Watts into it and have it sound good (in fact, it might just break the speaker…)
