And while a bit outdated, you can use LZW compression and the GIF
format since the US and European patents for LZW are expired.

Abbes, it is better to include the attribution lines in your posts.

You need to tell us whether your interest is researching algorithms,
or having a good implementation you can obtain quickly.
You're unlikely to be able to out-research the Xvid developers
all on your own.

I can't afford it. i was thinking of a (progressive transmission)
algorithm like embedded zero tree wavelet (EZW) or SPIHT...any
thought?

In addition to what others have posted.
video: AVCHD (licensed from Sony and Canon)

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.

Don't forget about the licensing fees.

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
