MPEG Royalties:

Depending on your use of MPEG, there may be a licensing fee due to the companies which control the patents behind MPEG. For MPEG-2 use, the licensing agreement and fees are normally handled by MPEG LA, a company that has secured the necessary rights from the various MPEG-2 patent holders to license MPEG-2 to developers. For more information on MPEG-2 licensing, please visit MPEG LA's site at: http://www.MPEGLA.com

MPEG-1 licensing is not as well organized and defined as MPEG-2 licensing, and it is somewhat unclear what your licensing responsibilities are when using it. You may find helpful information at: http://www.mpeg.org and http://drogo.cselt.stet.it/mpeg

Please contact these organizations for the latest info, because these royalties fees change regulary.
