DIVX (Digital Video Express) was a video rental system developed by Circuit City Stores and other entertainment industries in United States which required special discs and players to function. In order the system to work the DIVX Player should connect to a telephone line which is used to track the status of the DIVX disk and as a link to DIVX server for update account status and other security updates.
