Divx may refer to any of the following:
1. DivX is a compression scheme that makes a movie 8 to 12 times smaller with little quality loss. DivX is widely being used for compressing computer video files and even DVD files to fit onto a standard CD. Many individuals believe that DivX will be the MP3s of Video files.
2. Short for DIgital Video eXpress, Divx was a DVD-ROM developed and promoted by several large companies including Disney, Dreamworks SKG, Paramount, and Universal. The idea behind Divx is to help add copy protection security. With Divx, a movie or other media is loaded onto a disc and only playable for a duration of time, often two days. Each Divx player is connected over the telephone to allow communication between the Divx player and a central server, allowing it to exchange billing information.
The Divx player is more expensive than a traditional DVD drive and current DVD drives do not support Divx, therefore, a new player must be purchased to play a Divx disc. Divx discs were only available through local Circuit City Stores until June 16, 1999. Digital Video eXpress announced it would discontinue operations, but existing, registered customers would be able to view discs during a two-year phase-out period.
