The video you are about to watch is actually a one hour class at MIT. Normally such a video will be many levels above the type of video which I think will be understandable by our general membership. If you watch it however, in a few minutes professor Freeman all of a sudden comes down to everyone's level and actually talks about high-resolution audio! That goes on for many minutes until he gets technical again around 30 minutes. Put up with that and a few minutes later there is more useful knowledge presented at high level. The video ends on how JPEG compression works starting with DCT transforms which you can skip.
I hope to find more videos explaining the concept easier but for now, I think this is a very good advanced video to have here as the placeholder:
BTW, the production qualities are poor here with overblown contrast in slides and low resolution video. It is however HTML 5 and can be sped up although I don't recommend it unless you are an engineer and watching this as a refresher of your college days .
