“The program offers a brief history of digital media, a quick summary of the sampling theorem, and myriad details of low level audio and video characterization and formatting. It’s intended for budding geeks looking to get into video coding, as well as the technically curious who want to know more about the media they wrangle for work or play.”
The first video is about 30 minutes long, but quite entertaining and packed full of great information. It’s done by “Monty” Montgomery himself, and believe me, he knows what he’s talking about. If you were ever curious about how it all works, this is definitely worth your time.
If you’re not familiar with The Xiph.Org Foundation, they are passionate advocates of open source, and in their words are about “bringing open source and open source ideals to multimedia…and media on the Internet needs us.”
