I am looking for the commonly used algorithms to compress images/
videos for transmission over the internet. could you please name me
these algorithms and/or papers. Cheers

For video H.264, which is a subset of MPEG-4, is the most standard but
there are no "free" versions of it.

Xvid is probably the best combination of being sort-of standard,
good performance, and "free".

For still images you problem is much simpler, just use JPEG.
