Presents a design for a VOD server. The important thing in designing a service like VOD is the availability to a wide customer base and the real on demand response to their requests. Availability to marry simultaneous users and random access are the key issues here, since this feature will make the design suitable for other multimedia services, such as full interactive video systems and library searching. The control mechanism processes in parallel the incoming customer requests and keeps providing the users with the correct piece of information, in this case the correct location in the movie.
