Pointers on video/audio codec needed

[sureshs]

Hi,

I'm doing a research project on internet codecs. I need to find out on usage of famous video codecs such as divx and famous audio codecs such as aac. Can you give me pointers to where I can find such info?

I need to know about which ones are famous, background on each, tools to play at home with them, what do users want... At the end, I would need to do a powerpoint presentation in front of my class on internet codecs.

Any help would be greatly appreciated!

Thanks,
Suresh
